Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Fig. 1 to Fig. 4 shows a mode of execution of the utility model jetting machine separated type cylinder body plunger pump.The utility model is made up of pump case 1, the pump housing 2, plunger frame 4.It comprises the pump housing 2 and is installed in the swash plate (not shown) in described plunger frame 4 outsides, a plurality of plungers 41 that described swash plate promotes, one low pressure intake pipe 11 and high-pressure outlet 12 respectively is set in the described pump case, and described low pressure intake pipe and high-pressure outlet are set up in parallel in the same way on described pump case.Water-in and water-out tube side-by-side then of the present utility model is placed on the pump case towards unanimity, is more conducive to installing and using of client.
One end of the described pump housing is provided with a displaceable pump case 1, and the other end of the described pump housing 2 connects a plunger frame 4; Described a plurality of plunger 41 is arranged in a plurality of plunger holes of described plunger frame 4.
One siphoning installation 13 is set in the described high-pressure outlet 12; Be used to draw washing agent.Its mounting type installs a siphon joint and an one-way valve for being threaded in corresponding positions.When pump work during at low-pressure state, can draw washing agent by this siphoning installation, be that one-way valve can prevent that high pressure water from leaking outside from the siphon joint and be operated in high pressure conditions.
One safety valve 14 is set between described low pressure intake pipe 11 and the high-pressure outlet 12, and described safety valve 14 connects a sensitive switch that is used for cutting off the electricity supply and closes rifle arresting gear (not shown).
Be set with protruding taper pin 91 on the mounting plane 6 of described pump case, the junction plane that the described pump housing matches with described pump case mounting plane is provided with recessed taper pin-hole 92, described protruding taper pin 91 and described recessed taper pin-hole 92 mutual precision-fit.So, pump case adopts cooperating of two pairs of taper concaveconvex structures with the pump housing, has the mistake proofing effect when assembling.
Plane sealing is adopted in sealing between the described pump housing and the pump case, and promptly the interior edge face of pump case is provided with a mounting plane 6, and a seal ring 8 is set between the junction plane of the described mounting plane 6 and the described pump housing.The described pump housing with plane that pump case combines on a low pressure water inlet flow channel 111 and high pressure outlet passage 121 respectively is set, described low pressure water inlet flow channel and high pressure outlet passage are isolated by the major trough and the secondary groove of described seal ring.
Described seal ring 8 is installed on the darker major trough 18 on the described pump case mounting plane 6, is arranged on the junction plane of the described pump housing with the corresponding more shallow secondary groove 19 of the darker major trough on the described pump case mounting plane.Described major trough 18 is irregularly shaped with more shallow secondary groove 19 profiles according to flow channel shape.
Described plunger frame 4 is fixedlyed connected by screw 5 with the described pump housing 2.The pump housing is to be fixed on the plunger frame by pump case, thereby structurally need not dispose connection with elements such as screw or bolts hole.Its discharge orifice 17 need not adopt follow-up machining mode and directly make on pump case.
When complete machine was worked, the described swash plate of motor driving also promoted three plungers 41 and pumps.When plunger was mobile from left to right, low pressure check valve 33 was opened, and the low-pressure water low pressure check valve of flowing through enters booster cavity, and this moment, high pressure one-way valve 32, total one-way valve 36 and described safety valve 14 were in closed condition.When plunger moved from right to left, low pressure check valve 33 was closed, and the current in the booster cavity are opened high pressure one-way valve 32 under the promotion of plunger, enter the unidirectional valve chamber 35 of high pressure, and flowed out through the stop valve of total one-way valve, high-pressure outlet 12 and high pressure water gun.Reciprocal will the pumping after the low-pressure water supercharging of taking turns under motor driving of three plungers forms pressure stable, flow is exported from high pressure water gun.When the high pressure water gun stop valve is closed or other unexpected factors cause under the situation that water outlet stops up, when the pump internal pressure raises rapidly, the action of the safety valve of pump is unloaded the water intake that is depressed into pump cover with the return port and the current by pass on the pump cover of excess pressure in the pump by outlet pipe, safety valve 14 touches sensitive switch simultaneously, cuts off working power.When opening the high pressure water gun stop valve again, pump is started working again.
The utility model compact structure is simplified processing, is convenient to assembling, and entire pump only need be processed several internal threads, the assembling of can putting into production.
