Abstract

A stand-alone driving device to drive high and low pressure hydraulic pumps is disclosed by the utility model, which comprises a hydraulic oil pump (1). The utility model is characterized in that the hydraulic oil pump (1) is connected with a high-pressure hydraulic pump motor (3) and a low-pressure hydraulic pump motor (4) through a valve block (2), and the high-pressure hydraulic pump motor (3) and the low-pressure hydraulic pump motor (4) are connected with a high-pressure hydraulic pump and a low-pressure hydraulic pump, respectively. The utility model is a stand-alone driving device to drive high and low pressure hydraulic pumps in simple structure, needing few funds, safe and reliable.

Description

A kind of unit drives the drive unit of high and low pressure water pump
Technical field:
The utility model relates to the actuation techniques field, is the drive unit that a kind of unit drives the high and low pressure water pump specifically.
Background technique:
At present, a lot of special cars are furnished with two cover drive systems, are furnished with two cover water circuit systems as existing high-pressure sewer flushing vehicle, high pressure water route and low pressure water route, and two overlap independently drive system, and low-pressure pump is to be driven by the chassis power take-off; The drive form of high-pressure water pump generally has following several: have plenty of by an assistant engine driving; Have plenty of in engine in situ and install sandwich power take-off or transfer case additional, what also have utilizes two power takings on the engine in situ gearbox, drives high-pressure water pump by transmission shaft; Utilize the secondary moving high-pressure water pump that drives to cause equipment investment big, the cost height; Carry out power taking by changing the device of chassis on starting, can't control the rotating speed of high-pressure water pump effectively, the change of engine speed will have influence on the fluctuation of the pressure and the flow of high pressure water, and misoperation also can cause the high-pressure water pump hypervelocity, causes the damage of high-pressure water pump.
Summary of the invention:
The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and the drive unit that provides a kind of unit to drive the high and low pressure water pump has solved mainly that existing two cover independent driving system complex structures, equipment investment are many, the problem of safety reliability difference.
In order to achieve the above object, the utility model is achieved in that a kind of unit drives the drive unit of high and low pressure water pump, it comprises hydraulic-pressure pump 1, and its special way is that hydraulic-pressure pump 1 is connected with low-pressure pump motor 4 with high-pressure water pump motor 3 respectively by valve group 2; High-pressure water pump motor 3 is connected with low-pressure pump with high-pressure water pump respectively with low-pressure pump motor 4.
A kind of unit of the present utility model drives the drive unit of high and low pressure water pump, establishes flow control valve 5 and 6 respectively between its described valve group 2 and high-pressure water pump motor 3 and the low-pressure pump motor 4.
A kind of unit of the present utility model drives the drive unit of high and low pressure water pump, hydraulic-pressure pump is by two pump motors of valve group control, two pump motors are controlled high-pressure water pump and low-pressure pump respectively, in pump drive system, install hydraulic flow control valve additional, the rotating speed of control of pump, to guarantee that water pump does not exceed the speed limit, prolong the working life of water pump, thereby realize that unit drives the high and low pressure water pump.
Compared with the prior art the drive unit that a kind of unit described in the utility model drives the high and low pressure water pump has following good effect: 1, simple in structure, equipment investment is few, also can on former car, change, do not need actuating units such as former vehicle chassis motor are done any change, oil pump or the motor of changing different displacements by the rotating speed requirement of different water pumps can satisfy use; 2, easy for installation, performance is safe and reliable.
Description of drawings:
Fig. 1---the utility model work structuring schematic representation.
Among the figure: 1-hydraulic-pressure pump 2-hydraulic valve bank 3-motor 4-motor 5-flow control valve 6-flow control valve
Embodiment:
In order to understand better and to implement, provide specific embodiment below in conjunction with accompanying drawing and describe the drive unit that a kind of unit of the utility model drives the high and low pressure water pump in detail.
Embodiment 1, referring to Fig. 1, hydraulic-pressure pump 1 is installed on the power take-off of vehicle chassis, hydraulic-pressure pump 1 is connected with hydraulic oil container by pipeline, hydraulic-pressure pump 1 is connected with low-pressure pump motor 4 with high-pressure water pump motor 3 respectively by valve group 2, high-pressure water pump motor 3 is connected with low-pressure pump with high-pressure water pump respectively with low-pressure pump motor 4, between valve group 2 and high-pressure water pump motor 3 and the low-pressure pump motor 4 flow control valve 5 and 6 is installed respectively.
A kind of unit described in the utility model drives the drive unit of high and low pressure water pump, during work, the chassis power take-off drives hydraulic-pressure pump work, when the needs low-pressure pump is worked, hydraulic valve bank control hydraulic oil drives the low-pressure pump motor, low-pressure pump motor driven low-pressure pump rotates, and carries out low pressure watering work; When the needs high-pressure wash, hydraulic valve bank control hydraulic oil drives the high-pressure water pump motor, and high-pressure water pump motor driven high-pressure water pump rotates, and carries out high-pressure wash work; By regulating flow control valve to guarantee the oil hydraulic motor constant speed, water pump hypervelocity phenomenon can not appear, prolong the working life of water pump.
