As illustrated, including cleaning vehicle body, the cleaning vehicle body includes vehicle frame 1, the driver's cabin being arranged on vehicle frame 1
2 and for the water tank 3 for the stainless steel type for filling water, the water tank 3 includes top, bottom and both sides sidepiece, at the bottom of the water tank 3
The fluid power system that sprays water with high pressure is connected with the outer wall in portion,
The fluid power system that sprays water with high pressure includes the water pipe 1, water filter 5, water pump water level monitor interconnected
6th, water cooling exchanger 7, water pipe 28, water pump 9, water pump hydraulic drive motor 10, control valve 11, hydraulic pump 12；
The water filter 5 is arranged on the outer wall of the bottom of water tank 3, and the water cooling exchanger 7 sets and is connected to the car
On frame 1, the water pump 9, water pump hydraulic drive motor 10 are arranged at the rear of the water cooling exchanger 7；
The hydraulic pump 12 is used to drive water pump hydraulic drive motor 10 by control valve 11, by water pump hydraulic drive motor
10 drive water pumps 9 are operated, and then the water in water tank 3 enters water filter 5 from the entrance point of water pipe 1, then enters water by water filter 5
Pump water level monitor 6, enters water cooling exchanger 7 after water is completely filled with water pump water level monitor 6 by pipeline, then by water pipe
28 finally enter water pump 9；The effective suction using water pump during this water route, has used cleaning water source to greatest extent
Service efficiency, while water pump 9 can be supplied, also cooling system oil temperature while water pump 9 are supplied.
Water route working line 13 is additionally provided with one end of the water pump 9；Described water route working line 13 is used for water outlet.
Exhaust gate valve is provided with one end of the water pump water level monitor 6；When being initial started up in the course of work of water pump 9,
And when thering is bubble to be mixed into pipeline, water can be reached by the exhaust gate valve vent gas on water pump water level monitor 6
Pump 9 is not emptied.
Hydraulic oil container 14 is also associated with the hydraulic pump 12.
Water cooling exchanger 7, the volume of the water cooling exchanger 7 are in series with the fluid power system that sprays water with high pressure
It is small, effectively using water source, solve hydraulic system cooling problem.
The working method of control valve 11 in the utility model mesohigh water spray fluid pressure drive device includes load-sensitive
Feedback hydraulic system, described load-sensitive feedback hydraulic system is made up of following several big parts：(1) axial variable displacement plunger pump；
(2) load-sensitive feedback valve group；(3) piston motor；(4) fuel tank and its annex；
Its operation principle is:Swash plate is failure to actuate when axial variable displacement plunger pump dallies, and now axial variable displacement plunger pump is only exported
A small amount of hydraulic fluid flow rate in pump by letting out, and Direct Segueuce Valve initial setting protection pressure is used as change in load-sensitive feedback valve group
Measure the driving pressure that swash plate drives in axial plunger pump；Two-bit triplet magnetic valve commutates in load-sensitive feedback valve group, at this moment oily
A small amount of flow in road is under Direct Segueuce Valve set pressure by LS mouthfuls of entering variable pump swash plate driving hydraulic oil cylinder drivings of valve group
Swash plate is acted, and now the variable function of axial variable displacement plunger pump starts to start, and drives piston motor work；Axial variable displacement plunger pump
After work, two-bit triplet magnetic valve is worked in right position, and now a small amount of flow is controlled by the damping hole in valve group through LS mouthfuls
The variable of swash plate；When external loading changes, full adjusting type big flow throttling valve outlet pressure in valve group can be made to change,
Changed by the flow of damping hole, so that being changed through the LS mouthfuls of flows for entering swash plate, make the output stream of variable pump
Amount changes, and reaches that pump changes the function of discharge capacity respective change according to load, so as to reach the effect of energy-saving and emission-reduction.
Direct Segueuce Valve in valve group can produce a back pressure, and this back pressure can just ensure that piston motor can be smooth
Start, be short of power due to being opened when motor is initial started up so as to avoid and cause motor walking and interior let out.
In order to realize the realization for meeting the drive motor variable speed that water pump to be needed is swept in different washing：Pilot stage in valve group
Proportional pressure control valve can realize that valve element is in optional position, and valve port optional position is realized by changing the electric current in ratio coil
Aperture, is shunted to the flow for flowing through damping hole, is flowed through the flow consecutive variations of LS mouthfuls of entering variable pump swash plates, is made variable
Pump output flow can be with consecutive variations, so as to realize the variable speed of piston motor.
The characteristics of utility model technology：
(1) collective effect for feeding back valve group by variable pump and load-sensitive can realize the energy-conserving action of system；
(2) motor variable speed can be realized；
(3) motor initial start is shielded.
(4) axial variable displacement plunger pump can produce very big heat in the maximum pump discharge course of work, also be gone here and there in this water route
Water cooling exchanger is associated with, small volume, effectively using water source, effectively solves hydraulic system cooling problem.
The utility model changes the output of water pump 9 by control valve 11, can control degree height, and degree of power conservation is high；It is maximum
Change make use of water source, the advanced maximized utilization rate for improving water source of water cooling exchanger 7 before intake pump 9；Exhaust gate valve
Setting be effectively protected water pump 9, extend service life, also make the certain buoyancy of holding of water pump 9, make water pump 9 more
Smoothly running.
