Description
(1) technical field
The utility model relates to a kind of hydraulic test equipment, is used for the simulation actual effect test of Hydraulic Drive in Vessel valve member, oil cylinder, motor.Belong to the shiprepair equipment technical field.
(2) background technology
In the turbine repair procedures of boats and ships, hydraulically operated equipment (HOE) has accounted for very big proportion, the quality of the repairing of Hydraulic Elements determined system in debug process smoothly whether.And often the workshop repair finish after, static test can not meet the demand of operating mode fully, the existence of hidden danger has caused much does over again, and has both increased cost, again the theory of making good service is sowed seeds of future trouble.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and carries out the simulation that dynamic actual effect is tested to repairing element, can find hidden danger, the hydraulic test bench of dealing with problems more accurately sooner.
The purpose of this utility model is achieved in that a kind of hydraulic test bench, comprise first hydraulic oil pump, second hydraulic oil pump, reversal valve and oil cylinder, first hydraulic oil pump links to each other with the suction inlet filtrator with the second hydraulic oil pump oil-in, oil-out links to each other with two retaining valve oil-ins respectively, two retaining valve oil-outs converge the back and link to each other with the oil-in of reversal valve, the oil-in of reversal valve also connects a surplus valve, the oil-in of reversal valve also connects air hose by another retaining valve and the 3rd stop valve, two actuator ports of reversal valve insert more than two with wrapping by first stop valve and second stop valve respectively, with contracting out mouth inserts oil cylinder respectively by the 4th stop valve and the 5th stop valve rod chamber and rodless cavity, the oil return opening of reversal valve inserts return filter more than two.
Ultimate principle:
Basic principle is the constant-voltage system of fixed displacement pump+surplus valve; The speed governing of throttling valve oil inlet and oil return is adopted in speed governing; What the meta technical ability of operating valve adopted is the M type, and the time off-load of the big department of pump can be energy-conservation; What pressurize was adopted is that stop valve is closed, and the simulation of load produces back pressure with the opening of stop valve.
The valve member major part is fixed on above the integrated package, compact conformation, and easy accessibility, simple to operate.Electric be provided with several protection switches, can be when surplus valve go wrong, outage automatically, protection motor and pump.
The beneficial effects of the utility model are:
