Abstract
The utility model discloses a slurry agitator hydraulic system, oil circuit the control unit including oil tank, motor, hydraulic pump and connection hydraulic pump, oil circuit the control unit is connected with the slurry agitator through slurry agitator control module, the hydraulic pump is constant voltage variable piston pump, just constant voltage variable piston pump is provided with two, slurry agitator control module puddles the agitator and is provided with a plurality ofly respectively, two constant voltage variable piston pump connect one respectively combined action is in a plurality of behind the oil circuit the control unit slurry agitator control module. Adopted constant voltage variable piston pump in slurry agitator hydraulic system, when agitating unit met great load at work, its discharge capacity reduced, when this load did not exist, pressure resumeed initial condition again, and consequently, when the load increaseed, the motor can not overload to the power consumption under this kind of operating mode has obviously been reduced.
Description
Technical field
The utility model relates to hydraulic control field, particularly relates to a kind of slurry agitator hydraulic system.
Background technology
The stirring action of slurry agitator realizes by hydraulic system. Existing mud stirring hydraulic system is adoptedWith constant displacement pump, in the time that agitating device runs into compared with heavy load at work, can cause motor overload; When more negativeCarry when reducing or not existing, pump delivery is constant, causes power attenuation serious.
Summary of the invention
The purpose of this utility model is to provide a kind of mud stirring that can regulate according to load pump deliveryHydraulic system.
For this reason, the technical solution of the utility model is as follows:
A kind of slurry agitator hydraulic system, comprises the oil of fuel tank, motor, hydraulic pump and connecting fluid press pumpRoad control module, described oil path control unit is connected with slurry agitator through slurry agitator control module, instituteStating hydraulic pump is constant pressure variable plunger pump, and described constant pressure variable plunger pump is provided with two, and described mud stirsMix device control module and slurry agitator and be respectively arranged with multiplely, described two constant pressure variable plunger pumps connect respectivelyAfter connecing a described oil path control unit, acting in conjunction is in multiple described slurry agitator control modules.
Described oil path control unit comprise the Pressure gauge that is connected on described constant pressure variable plunger pump output pipe,Pressure sensor and electromagnetic relief valve.
Described slurry agitator control module comprises solenoid directional control valve, flow sensor, one-way throttle valve and fixedAmount hydraulic motor; One end of described flow sensor and one-way throttle valve is connected respectively described solenoid directional control valve,The other end connects respectively described constant displacement hydraulic motor.
The beneficial effects of the utility model are as follows:
In slurry agitator hydraulic system, change the constant displacement pump of original system into constant pressure variable plunger pump, whenWhen agitating device runs into compared with heavy load at work, its discharge capacity reduces (being that rotating speed slows down); When this load is not depositedTime, pressure returns to again original state. Like this, in the time that load strengthens, motor can not overload, and brightThe aobvious power attenuation having reduced under this operating mode.
