Abstract
The invention discloses a reversing oil pump station device. An oil pump body and a reversing valve body are manufactured or combined as a whole to be connected with a motor; a reversing lever and the reversing valve body are assembled together; a control handle is provided with handle contacts which correspond to an upper contact and a lower contact; during operation, the control handle is pressed, hydraulic oil enters an oil cylinder through a pipe B, and the oil cylinder is extended; when hydraulic transmission reversing is required, the control handle is lifted, the hydraulic oil enters the oil cylinder through a pipe A, and the oil cylinder is contracted; when the control handle is in the middle position, the handle contacts are not in contact with the upper contact and the lower contact, and the reversing oil pump station device is in a service-unavailable state.
Description
Technical field
The present invention relates to a kind of hydraulic control system technical field, especially a kind of Reversing oil pump station arrangement.
Background technique
At present in machinery hydraulic control system field, especially the hydraulic station of hydraulic pressure transfer commutation control aspect is not one, all need the connections such as the voltage-controlled product of many kinds of liquid, electronics electrical control member to complete afterwards hydraulic pressure transfer commutation, caused hydraulic work unstable, be not suitable for the defect such as low temp operation, bad maintenance.
Summary of the invention
In order to overcome at present in machinery hydraulic control system field, especially the hydraulic station of hydraulic pressure transfer commutation control aspect is not one, all need the voltage-controlled product of many kinds of liquid, the connections such as electronics electrical control member completed hydraulic pressure transfer commutation afterwards, cause hydraulic work unstable, be not suitable for low temp operation, the deficiency of the defects such as bad maintenance, the invention provides a kind of Reversing oil pump station arrangement, this Reversing oil pump station arrangement adopts commutation valve body and oil pump body at design aspect, low voltage motor is integrated, power acquisition manipulates motor start-up or stops with low voltage zero line, having realized control handle once-through operation is that actuating motor completes again hydraulic pressure transfer commutation, be more suitable for low temp operation.
The technical solution adopted for the present invention to solve the technical problems is: first oil pump body is manufactured or is combined into one with commutation valve body and is connected with motor, reversing bar and commutation valve body are assembled together, on control handle, be provided with handle contact and and upper contact, lower contact is corresponding, control handle is connected with reversing bar, oil cylinder is by A oil pipe, A oil out port on B oil pipe and commutation valve body, B oil out port connects, on reversing bar, be provided with reversing bar A oil duct, reversing bar B oil duct and reversing bar back oil road, on commutation valve body, be provided with back oil road and valve body oil input channel, on oil pump body, be provided with oil pump oil outlet and oil pump filler opening, valve body oil input channel and oil pump oil outlet connect, fuel tank is by oil pump filler opening, back oil road and commutation valve body, oil pump body connects.In the time of operation, operate control handle to pressing down, at this moment handle contact and lower contact contact start motor, reversing bar upward sliding is connected valve body oil input channel, reversing bar B oil duct, B oil out port simultaneously, reversing bar back oil road also leads to A oil out port, back oil road simultaneously, hydraulic oil just enters oil cylinder by B oil pipe, oil cylinder is extended, and at this moment the hydraulic oil of the oil cylinder the other end just enters fuel tank by A oil pipe, reversing bar back oil road, back oil road.In the time that needs hydraulic pressure transfer commutates, operation control handle upwards lifts, at this moment handle contact and upper contact contact start motor, reversing bar down sliding is connected valve body oil input channel, reversing bar A oil duct, A oil out port simultaneously, reversing bar back oil road is also connected with B oil out port, back oil road simultaneously, hydraulic oil just enters oil cylinder by A oil pipe, and oil cylinder is shunk, and at this moment the hydraulic oil of the oil cylinder the other end just enters fuel tank by B oil pipe, reversing bar back oil road, back oil road.Control handle handle contact in the time of neutral position does not contact with upper contact, lower contact, and Reversing oil pump station arrangement is in the state of stopping operation.
The invention has the beneficial effects as follows, this Reversing oil pump station arrangement adopts commutation valve body and oil pump body, low voltage motor to be integrated at design aspect, power acquisition manipulates motor start-up or stops with low voltage zero line, having realized control handle once-through operation is that actuating motor completes again hydraulic pressure transfer commutation, be more suitable for low temp operation, simple in structure.
