Description
Technical field
The invention belongs to hydraulic-driven energy fields, more particularly, to a kind of flow monitor of hydraulic unit driver.
Background technique
It is in the prior art very universal thing with hydraulic offer energy source and power, but the energy used due to hydraulic-driven
Source is liquid, is occurred so many times having uncontrollable thing, then the flow velocity for the hydraulic holding movement how to control is just
Determine that the energy of offer is maintained on certain level, be unlikely to will appear energy deficiency or surplus and the unexpected feelings that occur
Condition.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of devices that can effectively detect hydraulic flow rates
In order to solve the above technical problems, the technical solution adopted by the present invention is that：
The flow monitor of the hydraulic unit driver comprising hydraulic unit driver, gear pump, detection unit and output are single
Member；
The detection unit includes liquid filter, pressure detector and load feedback device；
The hydraulic unit driver and gear pump pass through the first flow-stop valve and the second flow-stop valve and feedforward controller pipe respectively
Road connection；
The output end of the feedforward controller is connected with comparator and detection unit, and the detection unit and comparator are simultaneously
Connection, the output end of the comparator are connect with first switch valve, and the detection unit draws a signal piping, the detection pipe
Road is successively arranged liquid filter, pressure detector and load feedback device, the output end of the signal piping and described first
The output end of switch valve is connected and is connect again with second switch valve；
The output end of the second switch valve is fluid outlet port.
Further, the liquid filter, pressure detector and load feedback device connect with PID controller signal respectively
It connects.
The invention has the advantages and positive effects that：Hydraulic unit driver, gear pump, detection unit and output unit are matched
Conjunction, which is set up, not only may be implemented to hydraulic flow monitoring, moreover it is possible to be played during reducing liquid flowing to a certain extent
Energy loss, and then ensure that the accuracy in detection of hydraulic flow rates, moreover it is possible to it is further reduced liquid cost.
