Abstract
The present invention provides the flow monitor of a kind of hydraulic unit driver, it is characterised in that: include hydraulic unit driver, gear pump, detector unit and output unit；Detector unit includes liquid filter, pressure detector and load feedback device；Hydraulic unit driver and gear pump are connected with feedforward controller pipeline by the first flow-stop valve and the second flow-stop valve respectively；The outfan of feedforward controller connects comparator and detector unit, detector unit is in parallel with comparator, the outfan of comparator and the first switch valve connect, detector unit draws a signal piping, being sequentially provided with liquid filter, pressure detector and load feedback device on signal piping, the outfan of signal piping is connected with the outfan of described first switch valve and is connected with second switch valve.The present invention is possible not only to realize the flow monitoring to hydraulic pressure, moreover it is possible to serves the energy loss reduced in liquid flow process to a certain extent, and then ensure that the accuracy in detection of hydraulic flow rates.
Description
Technical field
The invention belongs to hydraulic-driven energy field, especially relate to the flow monitor of a kind of hydraulic unit driver.
Background technology
Energy source and power is provided to be the most universal thing with hydraulic pressure in the prior art, but the energy used due to hydraulic-driven
Source is liquid, occurs so many times having uncontrollable thing, then the hydraulic pressure how to control just keeps the flow velocity of movement
The energy determining offer is maintained on certain level, is unlikely to there will be energy deficiency or unexpected feelings that are superfluous and that occur
Condition.
