The utility model solves the problems of the technologies described above the technical scheme that is adopted: the water pump structure that adopts straight-through discharging type, it consists predominantly of low pressure water inlet check valve assembly, high pressure goes out the water one-way valve assembly, they are positioned on the pump cover, and be respectively level with vertical layout, dispose parts such as the thrust ball bearing assembly that is used for water and three oil sealings of lubricating oil and the assembly for plunger of forming by plunger, piston spring, piston spring supporting seat in the separate pump, forms by raceway plate, raceway assembly and face cam, water pump casing, motor, pump cover.Straight-through discharging type high-pressure cleaner working process is such: connect the water source, open hydraulic giant, promptly shutoff valve is opened, and low pressure water source (tap water) goes in the pump from inflow point; Meanwhile turn on the power switch, high-pressure cleaner is promptly started working: at this moment, motor rotates, the drive face cam rotates, the thrust ball bearing assembly that cam and raceway plate, raceway assembly, face cam are formed with three groups of assembly for plunger of forming by plunger, piston spring, piston spring supporting seat to the previous crops axial motion; Under three piston spring effects, make backward axially reseting movement respectively successively again; During to the previous crops axial motion, low pressure water inlet check valve is closed at plunger, and the high pressure check valve is opened, just with low pressure water source P in the pump
2Be press-fit into high pressure exhalant region P
1, when plunger under the piston spring effect, when making backward respectively axially reseting movement successively, the high pressure check valve is closed under pressure, and the check valve of low pressure water inlet is simultaneously opened, in the low-pressure water injection pump, make axially reciprocating so each time, just with low pressure water source P in the pump
2Be press-fit into high pressure exhalant region P
1, so move in circles; The inclination cam whenever revolves and turns around, three groups of assembly for plunger numbers of being made up of plunger, piston spring, piston spring support plug, piston spring, piston spring supporting seat are selected three groups of odd number for use, in order that obtain High-Pressure Water evenly output incessantly, and reduce the vibration and the heating of plunger pump.
Close hydraulic giant when suddenly, promptly shutoff valve is closed, and hydraulic pressure increases rapidly in the pump, and when its pump internal pressure surpassed the predetermincd tension of by pass valve medi-spring, by pass valve was opened, high pressure water P
1Let out to low pressure inhalant region P by overflow weir
2, the hydraulic pressure that increases rapidly in the pump is able to drop-down; Meanwhile, motor is still rotating, and goes into the higher-pressure region from the low pressure inhalant region is pressurized again, and so circulation is to keep high-pressure cleaner normal operation under constant compression force.
The utility model can also dispose relevant rifle immobiliser (herein expression), pump motor is closed after then closing rifle, thereby has finished the pass rifle and power cutoff carries out synchronously.Open hydraulic giant once more, high-pressure cleaner is in running order again.
Compared with prior art, when advantage of the present utility model is that the high-pressure hydraulic pump to cleaning machine quits work suddenly, can carry out the off-load safety guard-safeguard automatically; after guaranteeing that hydraulic giant cuts out; high-pressure hydraulic in the pump leaks rapidly and reduces pressure, and the motor that also can switch off the pump simultaneously quits work.
