Embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Fig. 1, Fig. 2 show a mode of execution of a kind of plunger-type pump of high pressure cleaner of the present invention.It comprises influent-effluent base 8, pump cover 5,3 three parts of the pump housing.Influent-effluent base 8 is made up of with water outlet 82 water intake 81 that is arranged in juxtaposition in the same way, and influent-effluent base 8 is fixed on the pump cover by screw 7.Pump cover 5 is fixed on the motor 1 by screw 16 with the pump housing 3.
Its middle pump body 3 is as the to-and-fro motion support of plunger 10, and a side is connected with motor 1, and opposite side links to each other with pump cover 5; Pump cover 5 is again the active chamber as plunger-type pump of high pressure cleaner of the present invention, and low-pressure water enters active chamber by low pressure check valve 4, flows out through the water outlet 82 of total one-way valve 11 from influent-effluent base 8 by high pressure one-way valve 6 after the supercharging again.Influent-effluent base water outlet 82 also has one to inhale joint 12 by cylinder and inhale the siphoning installation that nozzle 13 is formed with cylinder, and cleaning solution passes through in the siphoning installation inflow pump.Safety valve 14 is housed between water intake and water outlet; safety valve action when the pump internal pressure is too high; the water of the unidirectional valve chamber 17 of hyperbaric chamber 18 and high pressure is back to low pressure water-inlet cavity 41 releases of water intake by safety valve, and safety valve 14 is shut down assembly 15 and driven sensitive switches and cut off the electricity supply by closing rifle simultaneously.
The low-pressure intake 81 of a kind of plunger-type pump of high pressure cleaner of the present invention and high-pressure outlet 82 all are arranged on the influent-effluent base 8, can change by influent-effluent base, can finish the variation of intake-outlet direction, be easy to realize the seriation and the diversification of product, and can adapt to the jetting machine needs of various ways.
Low pressure check valve 4 is mounted and fixed on the outside end face 31 of the pump housing 3.Low pressure check valve 4 is pushed down the location by the pump housing 3, saves the fixing part of using, and saves cost, and is easy for installation.
3 high pressure one-way valves 6 that are installed on the pump cover communicate by the internal process hole.High pressure one-way valve 6 and stationary positioned are on the downside end face 83 of influent-effluent base 8.High pressure one-way valve 6 is pushed down the location by influent-effluent base 8, saves the fixing part of using, and saves cost, and is easy for installation.
Safety valve 14 is provided with a through hole 141 that communicates with low-pressure cavity 41, directly communicates with low-pressure cavity, has saved auxiliary hole.
Total one-way valve 11 communicates high pressure one-way valve 17 with water outlet 82, after the pass rifle is shut down, play the pressurize effect.
Water outlet 82 returning apparatus one siphoning installation of influent-effluent base, promptly at the water outlet 82 built-in siphon nozzles 13 of influent-effluent base, siphon joint 12 of outer side joint, between siphon joint and siphon nozzle, be provided with an one-way valve 19, prevent that at non-imbibition state be rifle when going out high pressure water, high pressure water leaks outside through the siphon joint.When rifle is in the imbibition state, produce negative pressure in the nozzle, one-way valve 19 is opened, and cleaning solution is by in the siphon joint inflow pump.
The working procedure of this pump is such: when motor 1 work, being installed in swash plate 2 on the axle of motor 1, to promote plungers 10 reciprocating.When plunger 10 was mobile from left to right, low pressure check valve 4 was opened, and low-pressure water is passed through intake tunnel 41 to water-inlet cavity 42 from water intake 81, enters active chamber 43 through low pressure check valve 4, and high pressure one-way valve 6, total one-way valve 11 and safety valve 14 are in closed condition at this moment.When plunger 10 moves from right to left, low pressure check valve 4 is closed, and the water in the active chamber 43 is opened high pressure one-way valve 6 under the promotion of plunger, enter the unidirectional valve chamber 17 of high pressure, and through always one-way valve 11, hyperbaric chamber 18 arrive water outlet 82, and flow out from high pressure water gun by high-voltage tube.
Three plungers 10 are under motor 1 drives, and reciprocal will the flowing out after the low-pressure water supercharging of taking turns forms pressure stable, flow, exports from high pressure water gun.When high pressure water gun cuts out or other accidental causes cause out under the situation of water slug; the pump internal pressure raises rapidly; safety valve 14 actions of pump; high pressure water in the unidirectional valve chamber 17 of hyperbaric chamber 18 and high pressure is back to the release of low pressure water-inlet cavity by safety valve 14, and safety valve 14 is cut off the electricity supply by closing rifle shutdown assembly 15 drive sensitive switches simultaneously.
The low-pressure intake of a kind of plunger-type pump of high pressure cleaner of the present invention and high-pressure outlet are arranged on same direction, make that the jetting machine that has disposed a kind of plunger-type pump of high pressure cleaner of the present invention is easy to use, beautiful shape.
