Abstract
The utility model relates to a multi-cylinder piston type diaphragm pump which belongs to the pump class of equipment for plant protection and is characterized in that each cylinder is arranged in the radial direction in a star shape, and a diaphragm is forced to make reciprocating motion by a piston; high pressure and high flow rate can be obtained, the stability is favorable, and the liquid discharging pressure and the flow rate of the diaphragm pump can be corrected optionally. The utility model can be used for physic liquor spray and sprinkling irrigation for farmlands and garden plants, environment sterilization, hygiene and disease control, highway water spray, spray and brushing for machines, vehicles, and buildings, liquor conveying in the industry, etc.
Description
The utility model belongs to equipment for plant protection: the pump class.
The diaphragm pump that prior art provided, piston is not connected with barrier film, the barrier film servo-actuated, the output hydraulic coupling, instability of flow, efficient is low, and vibration and noise are big.
Technical characterstic of the present utility model: each cylinder is for radially star is evenly distributed, and piston is connected with barrier film, forces the barrier film interlock, makes the pressure of output liquid, stability of flow, and the efficient height vibrates for a short time, and noise is low.
Accompanying drawings the utility model.
Fig. 1 is a multi-cylinder piston diaphragm pump structure schematic representation.
Fig. 2 is a multi-cylinder piston diaphragm pump left view.
Fig. 3 is that multi-cylinder piston diaphragm pump B is to view.
As shown in Figure 1, 2, 3: Multi-cylinder piston type diaphragm pump is made up of eccentric shaft 1, the pump housing 5, pump cover 10, bearing 21, clip 20, connecting rod 18, piston 15, barrier film 14, air chamber 23, cameral mantle 25, air chamber cover 27, check valve and pressure regulator valve.
Barrier film 14 middle parts are disc parts of sphere, with pump cover 10 limit, garden are pressed on the cylinder sleeve 19, and its center is pressed together with connector stud 12 locking caps 13 nuts 11 that are fastened on the piston 15. Pump cover 10 is provided with the check valve that valve seat 6 spools 7 valve springs 8 vavle shelves 9 form with the pump housing 5, air chamber 23 junctions, 27 of air chamber 23 and air chamber covers accompany cameral mantle 25, valve 26 is housed on the air chamber cover, total liquid outlet of air chamber 23 is equipped with pressure regulator valve handle 32, valve module of voltage regulation and Pressure gauge 36 that pressure regulation pin 33, release liquid back pipe 34, drain pipe 35 form. Eccentric shaft 1 usefulness drive end bearing bracket 2,3 two bearings 4 of nut, back-up ring 22 rear end caps 24 are installed the location with the pump housing 5. Piston and connecting rod connect with piston pin 16, back-up ring 17. Angle 28, connect bases 30 with nut 29 locking, with the pump housing 5 inner chamber pump covers 10 and barrier film 14, air chamber 23 and cameral mantle 25, liquid outlet 35 forms fluid passage.
This multi-cylinder piston diaphragm pump, eccentric shaft 1 connects motor or internal-combustion engine input torque, when being in position shown in Figure 1, piston is in extreme lower position, the volume maximum between barrier film and the pump cover, and this moment, the one-way valve of inlet began to close, the outlet one-way valve opens, because eccentric shaft rotation, piston promote barrier film the volume between barrier film and the pump cover is constantly diminished, intracavity liquid is pressed into air chamber through the outlet one-way valve and discharges through liquid outlet 35.When eccentric shaft forwards the extreme higher position to, volume reaches minimum between barrier film and the pump cover, discharge opeing finishes, after eccentric shaft turns over the extreme higher position, the fluid closed check valve, the feed liquor one-way valve opens, eccentric shaft is rotated further piston drive barrier film and moves down, volume constantly becomes big between barrier film and the pump cover, and liquid is in inlet one-way valve is inhaled into the chamber.When eccentric shaft forwards initial position to, the volume maximum between barrier film and the pump cover, feed liquor closed check valve, fluid one-way valve opens.Because the continuous rotation of eccentric shaft drives barrier film 14 through bearing 21, clip 20, connecting rod 18, piston 15 and does to force to-and-fro motion; Intracavity liquid is by cycle pressurization output.Because the utility model is that multi-cylinder radial star is evenly distributed, when eccentric shaft rotated, each cylinder piston was being made cyclic movement in turn, and the liquid outlet of each cylinder on pump cover compiles air inlet chamber and constantly export highly pressurised liquid by total liquid outlet 35.Cameral mantle 25 is airtight with air chamber cover 27, squeezes into Continuous pressure-controlled air inflation by valve 26, plays energy storage pressure regulation effect, makes the pressure of output liquid, and flow becomes into stable.The fluid pressure of exporting in the air chamber is discharged by total liquid outlet 35 through pressure regulator valve.Rotate the pressure regulator valve handle, the inclined-plane on it promotes pressure regulation pin 33 opens pressure regulator valve, and the liquid in the air chamber is discharged fast through release liquid return pipe 34.Lubricating cup 31 is located on the pump housing 5, and lubricating grease is lubricated for the relative movement position, and the fluid pressure of discharge, the available pressure regulator valve of flow size are regulated, and excess liquid can flow back to liquid tank from the release liquid return pipe.
Embodiment:
