Description

本発明はポンプに関し、特にモータによって流体がポンピングされるポンプ室と連通され、該ポンプ室の空気を外部へ排出する空気排出手段を備えて、該ポンプ室の吐出口に流体の逆流を防げるチェックバルブを備える真空強自吸式ポンプに関する。 The present invention relates to a pump, and more particularly to a pump that is communicated with a pump chamber in which fluid is pumped by a motor, and that includes an air discharge means for discharging the air in the pump chamber to the outside, and a check that prevents backflow of fluid at the discharge port of the pump chamber The present invention relates to a vacuum strong self-priming pump including a valve.

さらに詳しくは、ポンプ室内部の空気を強制的に外部へ排出させて、圧力差を生じさせ、モータによりポンピングされる流体をもっと簡単に 移動させる。また、作業時間も短
縮できて電力消費を最小化することによって、作業の効率性を向上させることができる真空強自吸式ポンプに関するものである。 More specifically, the air inside the pump chamber is forcibly discharged to the outside, causing a pressure difference, Before moving more easily fluid pumped by the motor. Further, by minimizing the power consumption can also be short <br/> reduced work time, to a vacuum strong self-priming pump capable of improving the efficiency of the work.

一般に、ポンプはある流体が該ポンプの吐出口より下側にある場合、該流体を上側まで強制的にポンピングさせる装置で、流体の移動または循環に使われている。
上記ポンプは稼動初期において、ポンプ室の内部に水を完全に満たさなければポンピングできないので、従来は受動または一定量の水を連続して供給しながら稼動するために、他のポンプを利用してポンプ室の内部の空気を排出して真空状態を作りながら水が満たされるようにしてポンピングを行っていた。 In general, a pump is a device that forcibly pumps a fluid to the upper side when the fluid is below the discharge port of the pump, and is used for movement or circulation of the fluid.
In the initial stage of operation, the pump chamber cannot be pumped unless the pump chamber is completely filled with water. Conventionally, other pumps are used to operate while continuously supplying a passive or constant amount of water. Pumping was performed by filling the water while discharging the air inside the pump chamber to create a vacuum.

しかし、上記のような従来のポンプ及び真空強自吸式真空ポンプはスラッジが多量に含まれた水等をポンピングする場合、上記水に含まれているスラッジによってポンピングが簡単に行われない問題点がある。 However, if the conventional pump and vacuum strong self-priming vacuum pump as described above for pumping the sludge is contained in a large amount of water or the like, pumped by sludge contained in the water it is not performed easily problems There is.

そして、上記ポンプは水を循環させる場合、水の温度は上昇し気泡が発生し、また上記気泡によってポンピングが円滑に行われなくなって水温を低めるために別途の水槽を設置しなければならないし、ポンプ室の充水状態を維持するための別途の真空ポンプを設置している。   When the pump circulates water, the temperature of the water rises and bubbles are generated, and pumping is not performed smoothly due to the bubbles, and a separate water tank must be installed to lower the water temperature, A separate vacuum pump is installed to keep the pump room full.

また、大容量移動式ポンプは受動又は真空ポンプの使用が不可能であるため、他のポンプで主ポンプを充満させなければならないので費用が増加される問題点がある。   In addition, since a large-capacity mobile pump cannot use a passive or vacuum pump, the main pump must be filled with another pump, which increases the cost.

本発明は上記の問題点を解決するために案出されたものとして、モータによって流体がポンピングされるポンプ室と連通されて上記ポンプ室の空気を外部へ排出させる空気排出手段を設置し、上記ポンプ室の吐出口での流体が逆流することを防ぐことができるチェックバルブを設置する。   The present invention has been devised in order to solve the above-described problems, and is provided with an air discharge means that communicates with a pump chamber in which fluid is pumped by a motor and discharges the air in the pump chamber to the outside. Install a check valve that can prevent backflow of fluid at the outlet of the pump chamber.

これによってポンプ室の内部の空気を外部へ強制的に排出させ圧力差を発生させること
で、モータによってポンピングされる流体をもっと簡単に移動させることができ、また作業時間も短縮し、電力消費を最小化させることが可能で作業の効率性を高めることができる真空強自吸式ポンプ を提供することを目的とする。 This forcibly exhausts the air inside the pump chamber to the outside and generates a pressure difference, so that the fluid pumped by the motor can be moved more easily, and the working time is shortened and power consumption is reduced.

図示したように、真空強自吸式ポンプ１は流体が移動される枠体８と上記枠体８に内設されるインペラ７、上記インペラ７を回転させるモータ２及び上記枠体８内部の空気を排出させて真空状態を維持する空気排出手段１００で構成される。 As shown in the figure, the vacuum strong self-priming pump 1 includes a frame body 8 in which fluid is moved, an impeller 7 provided in the frame body 8, a motor 2 for rotating the impeller 7, and air inside the frame body 8. It is comprised with the air discharge means 100 which discharges and maintains a vacuum state.

上記枠体８は内部に所定の大きさをもつ空間部となるポンプ室３と上記ポンプ室３に流体が吸入される吸入口５及び上記流体が吐出される吐出口６が形成され、また上記吐出口６にはポンピングされる水によって上記吐出口６を開放させて、常に吐出口６を閉鎖するように設置されるチェックパルブイ９が設置されている。   The frame 8 is formed with a pump chamber 3 serving as a space having a predetermined size, a suction port 5 through which fluid is sucked into the pump chamber 3, and a discharge port 6 through which the fluid is discharged. A check valve buoy 9 is installed at the discharge port 6 such that the discharge port 6 is opened by water to be pumped and the discharge port 6 is always closed.

上記ポンプ室３にインペラ７が回転可能に設置されることで、上記インペラ７の中央部には上記モータ２と繋がれた回転軸４が繋がれて構成される。
上記空気排出手段１００は、上記枠体８のポンプ室３の空気を排出させるように上記ポンプ室３と連通される空気排出管１１０と上記空気排出管１１０の流入口を開閉させる空気遮断部１２０及び上記ポンプ室３の空気をポンピングして移動させる空気ポンピング部１３０で構成される。 Since the impeller 7 is rotatably installed in the pump chamber 3, the central portion of the impeller 7 is connected to the rotating shaft 4 connected to the motor 2.
The air discharge means 100 includes an air discharge pipe 110 that communicates with the pump chamber 3 so as to discharge air from the pump chamber 3 of the frame body 8 and an air blocking portion 120 that opens and closes the inlet of the air discharge pipe 110. And an air pumping unit 130 that pumps and moves the air in the pump chamber 3.

上記空気遮断部１２０は、上記空気排出管１１０の流入口を開閉させることで、 内部
に浮力によって上下方向に移動されるようにブイ１２２が設置され、また上記ブイ１２２の上端部には上記空気排出管１１０の流入口に対応する開閉バルブが形成されて上記枠体８のポンプ室３に引入された流体によって上記空気排出管１１０を開閉させるようになる。 The air shut-off unit 120 opens and closes the inlet of the air discharge pipe 110 so that a buoy 122 is installed inside the buoy 122 so as to move up and down by buoyancy. An open / close valve corresponding to the inlet of the discharge pipe 110 is formed, and the air discharge pipe 110 is opened and closed by the fluid drawn into the pump chamber 3 of the frame 8.

すなわち、上記ポンプ室３に流体が引入されて水位が高くなると、上記ブイ１２２が上側に移動するようになって上記ブイ１２２の上端部に設置された開閉バルブが上記空気排出管１１０の流入口を閉鎖させるようになる。   That is, when fluid is drawn into the pump chamber 3 and the water level rises, the buoy 122 moves upward, and the open / close valve installed at the upper end of the buoy 122 is connected to the inlet of the air discharge pipe 110. Will come to close.

そして、上記ポンプ室３の水位が低くなると、上記ブイ１２２が下側に移動して上記空気排出管１１０の流入口が開放される。
上記空気排出管１１０は、上記空気ポンピング部１３０によってポンピングされるポンプ室３の空気が移動されることで、上記空気ポンピング部１３０は内部に設置されるダイアフラム円板１３２が直線往復運動して上記ポンプ室３の空気をポンピングするようになる。 When the water level in the pump chamber 3 becomes low, the buoy 122 moves downward and the inlet of the air discharge pipe 110 is opened.
In the air discharge pipe 110, the air in the pump chamber 3 pumped by the air pumping unit 130 is moved. The air in the pump chamber 3 is pumped.

上記空気ポンピング部１３０は内部に設置されるダイアフラム円板１３２と動力を伝達させる動力伝達部１３４及び上記動力伝達部１３４とダイアフラム円板１３２を連結させるロッド１３８で構成されて、上記空気排出管１１０の他端を開閉させる第１ポンピングバルブ１３１と上記第１ポンピングバルブ１３１に流入された空気が外部へ排出される第２ポンピングバルブ１３３が形成される。   The air pumping unit 130 includes a diaphragm disk 132 installed therein, a power transmission unit 134 that transmits power, and a rod 138 that connects the power transmission unit 134 and the diaphragm disk 132, and the air discharge pipe 110. A first pumping valve 131 that opens and closes the other end of the first pumping valve 131 and a second pumping valve 133 that discharges air that has flowed into the first pumping valve 131 to the outside are formed.

上記動力伝達部１３４は、上記回転軸４の外周面に沿って回転可能となるように 偏心
設置される偏心ホイール１３５と上記偏心ホイール１３５の外周面に沿って 回転可能と
なるように 回転リング１３６が設置され、また上記回転リング１３６と上記偏心ホイー
ル１３５の間には軸受け１３９及び上記偏心ホイール１３５を選択的に連結して上記回転軸４と 等しく回転させる電子式クラッチ１３７で構成される。 The power transmission unit 134 includes a rotatable along the outer peripheral surface of the eccentric wheel 135 and the eccentric wheel 135 eccentrically installed so as to be rotatable along the outer circumferential surface of the rotary shaft 4
Such so that the rotating ring 136 is installed in, and an electronic clutch for rotating equal to the rotating ring 136 and the rotary shaft 4 selectively connects the bearing 139 and the eccentric wheel 135 between the eccentric wheel 135 137.

上記ロッド１３８は、直線方向に移動されることにより両端部が上記ダイアフラム円板１３２と回転リング１３６に繋がれて上記偏心ホイール１３５の回転による回転リング１３６の位置変化に従って上記ダイアフラム円板１３２を直線方向で往復運動させて上記ポンプ室３の空気を外部は簡単に排出させることができるようになっている。   The rod 138 is moved in a linear direction so that both ends thereof are connected to the diaphragm disk 132 and the rotating ring 136, and the diaphragm disk 132 is linearly moved according to the position change of the rotating ring 136 due to the rotation of the eccentric wheel 135. By reciprocating in the direction, the air in the pump chamber 3 can be easily discharged to the outside.

この時、上記ロッド１３８は上記ダイアフラム円板１３２と回転リング１３６に固定されることにより場合によって相互ヒンジで繋がれて上記回転リング１３６の回転及び位置変化に従って直線方向に簡単に移動させることが望ましくて、上記軸受け１３９によって回転リング１３６が偏心ホイール１３５の外周面に沿って簡単に回転ができるようになる。   At this time, it is preferable that the rod 138 is fixed to the diaphragm disk 132 and the rotating ring 136 so that the rod 138 is connected by a mutual hinge in some cases and easily moved in a linear direction according to the rotation and position change of the rotating ring 136. Thus, the bearing 139 allows the rotating ring 136 to easily rotate along the outer peripheral surface of the eccentric wheel 135.

また、空気排出管１１０の吐出口を開閉させる第1ポンプバルブ１３１が上記空気ポン
ピング部１３０が設置されて上記空気排出管１１０で上記空気ポンピング部１３０方向で一方向で空気を移動させるようになる。 In addition, the first pump valve 131 that opens and closes the discharge port of the air discharge pipe 110 is provided with the air pumping unit 130 and moves air in one direction in the direction of the air pumping unit 130 through the air discharge pipe 110. .

そして、上記空気ポンピング部１３０の一側には第２ポンピングバルブ１３３が形成されて上記空気ポンピング部１３０内の空気を外部へ排出させるようになる。
即ち、上記モータ２によって回転軸４が回転すれば、電子式クラッチ１３７が上記回転軸４と等しく回転されて上記電子式クラッチ１３７に電源を入力させて上記偏心ホイール１３５を回転させるようになる。 A second pumping valve 133 is formed on one side of the air pumping unit 130 to discharge the air in the air pumping unit 130 to the outside.
That is, when the rotating shaft 4 is rotated by the motor 2, the electronic clutch 137 is rotated equally with the rotating shaft 4 and power is input to the electronic clutch 137 to rotate the eccentric wheel 135.

上記偏心ホイール１３５が回転すれば、上記偏心ホイール１３５の外周面に空回転となるように設置された回転リング１３６の位置変化に従って上記ロッド１３８が直線方向で位置が変化され、上記ロッド１３８の位置変化によって上記ダイアフラム円板１３２が直線往復運動をするようになる。   When the eccentric wheel 135 rotates, the position of the rod 138 is changed in a linear direction according to the position change of the rotating ring 136 installed so as to be idly rotated on the outer circumferential surface of the eccentric wheel 135, and the position of the rod 138 is changed. Due to the change, the diaphragm disk 132 reciprocates linearly.

上記ダイアフラム円板１３２が下側に移動すると、上記第１ポンピングバルブ１３１が開放されて上記枠体８ポンプ室３の空気が上記空気ポンピング部１３０内側空間に流入されて、上記ダイアフラム円板１３２が上側に移動するようになれば、上記第１ポンピングバルブ１３１が閉鎖されると同時に上記第２ポンピングバルブ１３３が開放されて空気ポンピング部１３０の空気が外部へ排出されるようになる。   When the diaphragm disk 132 moves downward, the first pumping valve 131 is opened, and the air in the frame 8 pump chamber 3 flows into the space inside the air pumping unit 130, so that the diaphragm disk 132 is If it moves upward, the first pumping valve 131 is closed, and at the same time, the second pumping valve 133 is opened, and the air in the air pumping unit 130 is discharged to the outside.

上記のような空気ポンピング部１３０の作動によって上記ポンプ室３の空気は外部へ排出されて流体を上記ポンプ室３に移動させて、上記移動された流体によって上記空気遮断部１２０のブイ１２２を上側に移動させて上記空気排出管１１０を閉鎖させて真空状態を形成するようになる。   By the operation of the air pumping unit 130 as described above, the air in the pump chamber 3 is discharged to the outside to move the fluid to the pump chamber 3, and the buoy 122 of the air blocking unit 120 is moved upward by the moved fluid. And the air discharge pipe 110 is closed to form a vacuum state.

これは従来ポンプの使用においてポンプ室に水を注いで空気層をとり除く效果として、別途の作業なしに簡単に水のポンピングができるだろう。
この時、図５で示したように、上記ダイアフラム円板１３２と上記ロッド１３８は少なくとも一つ以上設置されて上記動力伝達部１３４によって上記ポンプ室３の空気をもっと容易に排出させることができることで、上記それぞれのダイアフラム円板１３２とロッド１３８はお互いに連動されるように作動して上記ポンプ室３の空気排出を円滑にするのが望ましい。 This is the effect of pouring water into the pump chamber and removing the air layer when using a conventional pump, so that water can be easily pumped without any additional work.
At this time, as shown in FIG. 5, at least one of the diaphragm disk 132 and the rod 138 is installed, and the power transmission unit 134 can discharge the air in the pump chamber 3 more easily. The diaphragm discs 132 and the rods 138 are preferably operated so as to be interlocked with each other so as to smoothly discharge the air from the pump chamber 3.

また、上記ダイアフラム円板１３２とロッド１３８は少なくとも一つ以上で成り立つが
、直列または並列で繋げることにより上記空気排出管１１０の空気を排出させても良い。
即ち、上記各ダイアフラム円板１３２とロッド１３８が並列で繋がれる場合には上記空気排出管１１０の他端が分岐され、分岐された各他端は上記各ダイアフラム円板１３２によって空気が持続的に排出させることができるように上記動力伝達部１３４を基準で所定間隔で傾斜を成しながら設置される。 Moreover, although the said diaphragm disc 132 and the rod 138 consist of at least 1 or more, you may discharge the air of the said air exhaust pipe 110 by connecting in series or parallel.
That is, when the diaphragm discs 132 and the rods 138 are connected in parallel, the other end of the air discharge pipe 110 is branched, and air is continuously supplied to the branched other ends by the diaphragm discs 132. The power transmission unit 134 is installed while being inclined at a predetermined interval on the basis so as to be discharged.

そして、上記ダイアフラム円板１３２とロッド１３８が直列で繋がれた場合にも、上記各ロッド１３８は動力伝達部１３４に設置されてお互いに連動されて各ダイアフラム円板１３２とロッド１３８は上昇と下降が相互反対に作動するようになる。   Even when the diaphragm disk 132 and the rod 138 are connected in series, the rods 138 are installed in the power transmission unit 134 and interlocked with each other so that the diaphragm disks 132 and the rod 138 are raised and lowered. Will work in the opposite direction.

上記のように、空気ポンピング部１３０は別途の作動スィッチ(図示しない)を設置して作業者が直接作動させることで、上記作動スィッチを操作して上記電子式クラッチ１３７にオン-オフさせることで上記空気ポンピング部１３０を制御して空気排出手段１００を 制御するようになる。   As described above, the air pumping unit 130 is provided with a separate operation switch (not shown) and is directly operated by an operator, so that the electronic clutch 137 is turned on and off by operating the operation switch. The air discharge unit 100 is controlled by controlling the air pumping unit 130.

一方、図６で示したように上記空気遮断部１２０には位置センサー１４０を内設して上記ブイ１２２の位置を測定して、上記位置センサー１４０の測定値によって上記電子式クラッチ１３７を制御する制御部１５０がさらに具備されて長時間の使用において発生しやすい空気を選択的に排出させることにより自動化ができる。   On the other hand, as shown in FIG. 6, a position sensor 140 is installed in the air blocking unit 120 to measure the position of the buoy 122, and the electronic clutch 137 is controlled based on the measured value of the position sensor 140. The control unit 150 is further provided, and automation can be performed by selectively discharging air that is likely to be generated during long-time use.

すなわち、上記空気遮断部１２０のブイ１２２が上側に移動して開閉バルブが上記空気排出管１１０を閉鎖させれば、上記ブイ１２２の位置を上記位置センサー１４０が測定するようになって、上記測定値によって制御部１５０が上記電子式クラッチ１３７の動作を止められて上記偏心ホイール１３５の動作を中断させる。   That is, if the buoy 122 of the air blocking unit 120 moves upward and the open / close valve closes the air discharge pipe 110, the position sensor 140 measures the position of the buoy 122, and the measurement is performed. The controller 150 stops the operation of the electronic clutch 137 according to the value and interrupts the operation of the eccentric wheel 135.

上記偏心ホイール１３５の動作が止まると、上記ダイアフラム円板１３２の動作が止まって、上記空気ポンピング部１３０の作動が止まるようになって真空状態を維持することで水が上記吐出口６を通じて排出される。   When the operation of the eccentric wheel 135 stops, the operation of the diaphragm disk 132 stops, the operation of the air pumping unit 130 stops, and the vacuum state is maintained, so that water is discharged through the discharge port 6. The

そして、上記流体に含まれた気泡によってポンプ室３に空気層が発生すれば、上記空気遮断部１２０のブイ１２２が下側に移動して位置センサー１４０によって測定されて、上記測定値によって制御部１５０が上記電子式クラッチ１３７を動作させて上記偏心ホイール１３５を回転させることで、上記上記空気ポンピング部１３０を作動させて空気を外部へ排出させることにより真空状態を維持するようになる。   If an air layer is generated in the pump chamber 3 due to bubbles contained in the fluid, the buoy 122 of the air blocking unit 120 moves downward and is measured by the position sensor 140, and the control unit is controlled by the measured value. 150 operates the electronic clutch 137 to rotate the eccentric wheel 135, thereby operating the air pumping unit 130 to discharge air to the outside, thereby maintaining a vacuum state.

この時、図７で示したように、上記ポンプ室３の吸入口５の外側を包む水圧調節部１７０が設置され、上記水圧調節部１７０に空気排出手段１００によって排出された空気が供給されるように空気循環管１７２が設置される。   At this time, as shown in FIG. 7, the water pressure adjusting unit 170 that wraps the outside of the suction port 5 of the pump chamber 3 is installed, and the air discharged by the air discharging means 100 is supplied to the water pressure adjusting unit 170. Thus, an air circulation pipe 172 is installed.

上記水圧調節部１７０は内部が通空され上記吸入口５が位置されて、下端部に水圧チェックバルブ１７４が形成されて内部圧によって水の流入量を制御するようになって、上記空気循環管１７２は上記水圧調節部１７０の内部に空気を供給して上記吸入口５周辺の水を圧迫して上記吸入口５に水をもっと容易に引入させること真空強自吸式ポンプ１の性能をもっと向上させることができる。 The water pressure adjusting unit 170 is evacuated inside, the suction port 5 is positioned, and a water pressure check valve 174 is formed at a lower end portion to control the inflow amount of water according to the internal pressure. 172 more internal vacuum strong self-priming performance of the pump 1 that supplies the air pressure on the water around the suction port 5 is more easily pulling-water to the inlet 5 of the pressure adjusting unit 170 Can be improved.

また、図８に示したように、上記空気ポンピング部１３０を真空ポンプ１６０構成して上記ポンプ室３空気を排出させて、真空状態を維持することができることで、上記真空ポンプ１６０は上記モータ２によって作動するように回転軸４とベルトによって駆動されることが望ましく、場合によって別途の動力装置を利用して駆動させることもできる。   Further, as shown in FIG. 8, the vacuum pump 160 is configured by the vacuum pump 160 so that the air in the pump chamber 3 can be discharged to maintain the vacuum state. It is desirable to be driven by the rotating shaft 4 and the belt so as to be operated by, and in some cases, it can be driven by using a separate power unit.

そして、上記空気遮断部１２０には位置センサー１４０を内設して上記ブイ１２２の位置を測定し、上記位置センサー１４０の測定値によって上記真空ポンプ１６０を制御する制御部がさらに具備されて空気を選択的に排出させるによって自動化ができる。   The air shut-off unit 120 is provided with a position sensor 140 to measure the position of the buoy 122, and a control unit for controlling the vacuum pump 160 according to the measured value of the position sensor 140 is further provided. It can be automated by selectively discharging.
