Abstract
The invention provides a multifunctional cover plate and an impeller pump chamber, wherein the circumference of an opening at one end of the pump chamber facing a motor is provided with an annular groove; a corresponding annular channel is arranged on one surface of the cover plate opposite to the annular groove and locked into the annular groove; an embedded gasket is arranged between the cover plate and the pump chamber for sealing; the other surface of the cover plate is sleeved with a cover plate center; the contact surface on one side of the cover plate facing the motor is provided with a sealing cushion; an annular channel is also arranged on the edge of the cover plate center and locked into an annular groove of a connecting piece; an embedded metal ring is adhered to the outside of the annular groove of the pump chamber; and the embedded gasket is adhered to the embedded ring. The invention seals and blocks all the leakage caused by strong axial pressure generated by impellers in the pump chamber, eliminates pressure water and reduces abrasion by the arrangement of a mutual locking structure of the annular groove and the annular channel between the immovable pump chamber and the cover plate, between the cover plate and the cover plate center, and between the cover plate center and the connecting piece, and the special design of the sealing cushion. Moreover, the replacement cycle of the cover plate is prolonged from 7 to 10 days to more than one year, and the clear water lift is also improved by 15 percent under the condition of unchanged power.
Description
Technical field
The invention belongs to a kind of assembly of pump, multifunctional cover plate and impeller pump chamber.
Background technique
Existing sand pump, night, the body pump all will seal with a large amount of press waters, could guarantee the rated head and the flow of pump, and parts also could proper functioning, keeps certain working life.Because press water is consumptive, the sand pump that uses in industries such as some chemical industry, mines need consume a large amount of press waters.The sealing quality of pump, to the height of pump performance, working efficiency, influence greatly.The sealing life of existing sand pump, liquid pump is short, the replacing Sealing is frequent.To this, countermeasure is that the way of taking to improve sealing load water seals.With 3 cun sand pumps is example, will open press water and carry out dynamic water seal to it when its work, and the pressure of water is up to 3.5-4Kg/cm
2, it could be sealed.For another example, the pump of-platform lift 40M, almost the pressure of wiper seal water also is up to 3.5Kg/cm
2, the clear water consumption of every day reaches 72 tons more than, and-year gets off to want 23760 tons of water consumptions.Recycle even can reclaim 50%, also will finally exhaust 11880 tons.Waste to water resources is very surprising.In addition, Sealing is changed fast, will change once the maintenance expenses height in every 7-10 days.The reason that causes this situation is the structure of the impeller cover of sand pump and pump chamber and cooperates unreasonablely that the end thrust of pump is too big, poor sealing performance.
Summary of the invention
The objective of the invention is to propose on a kind of structure to cooperate rationally, good seal performance, can reduce or cancel press water, wear-resisting durable multifunctional cover plate and impeller pump chamber significantly, to overcome the shortcoming of prior art.
This multifunctional cover plate and impeller pump chamber that the present invention proposes, it is characterized in that pump chamber has annular groove around motor one end opening, one side on the other side has the corresponding ring ridge on the cover plate, the ring ridge is fastened in the annular groove, the edge packer seal is arranged between cover plate and pump chamber, the another side of cover plate is with in the cover plate, on the surface of contact of motor one side seal rubber pad is arranged in the cover plate.
The annular groove on cover plate and the pump chamber surface of contact and the ring ridge can be two-fold or the above fastening of two-fold.
The one ring ridge is also arranged on the edge in the cover plate, and clamp-buckle is in the annular groove of coupling.
The pump chamber annular groove is bonded with metal edge circle outward, and the edge gasket is bonded on the edge circle.
The present invention is by between between motionless pump chamber and cover plate, in cover plate and the cover plate, and the structure that annular groove and Huan Geng are interlocked is set in the cover plate and between the coupling, add the peculiar design of seal rubber pad, the seepage that the powerful axial pressure that impeller produced during with work in the pump chamber is brought all sealing blocks.Changing seepage between the cover plate of existing pump chamber presses and will lean on the way of offsetting greater than the high pressure clear water of the working pressure of pump.Cancel press water, only needed the cooling water of low pressure.Thereby saved clear water consumption greatly, and prolonged the working life of Sealings such as cover plate significantly, the replacement cycle was changed once from existing 7-10 days, extended to 1 year and just changed once.Save maintenance and maintenance cost, improved manufacturing efficiency.
The present invention is combined with the seal action except that cover plate and impeller, also with pump chamber good seal action is arranged.
Because the sealability of pump is greatly improved, under the constant situation of power, the clear water lift has also improved 15%.

Embodiment
With power is that 7.5KW, 3 inches sand sand pumps are example, is connected to plane contact in the pump chamber of existing design, cover plate, the cover plate and between the coupling, and the clear water pressure that needs during work is 3.5-4Kg/cm greater than working pressure
2(being roughly equal to 343-392KPa) could proper functioning.Component wear is fast, has only 7-10 days working life.
This example is transformed with the sand pump of same specification.Shown in Fig. 1-8, the groove ridge on cover plate 6 and pump chamber 3 surface of contact fastens to two-fold fastens, and promptly the ring ridge 8 is first weight on annular groove on the cover plate 7 and the pump chamber, and a circle ring ridge of cover plate outermost and an annular groove on the pump chamber are that second hard smash is closed.Surface of contact between cover plate and pump chamber has just carried out five right angle bendings like this, and axial pressure is just fallen sharply rapidly, disappears at last.For the purpose of trustworthy, on outmost turns, seal fully and block with the mode of glued metal edge circle 1 and edge gasket 2.The axial seepage of pump chamber is just thoroughly eliminated.
Outside the cover plate, because the seal approach of the axle of impeller is arranged, axial seepage may be just quite little, but in order to stop the seepage in the cover plate and between the coupling, and this example is provided with one deck seal rubber pad 9 again in cover plate with on the surface of contact of coupling.All the other structures of pump are with existing identical.NM component label as mentioned above.
Improved pump only needs 0.4Kg/cm
2Cooling water (39.2KPa) can be sealed the seepage that axial pressure is brought fully, and a day water usage only has 500Kg.On probation through certain enterprise practical, Sealings such as cover plate did not change once in 1 year, so far still in normal use.By calculation of price per ton 4 yuan, a pump can be saved 4.6 ten thousand yuan clear water expense and corresponding supercharging facility for enterprise is annual.Also have a large amount of replacing Component and the expense of maintenance, economic benefit is fairly obvious.Because the sealability of pump is greatly improved, under the constant situation of power, the clear water lift has also improved 15%.
