Abstract
The utility model discloses an overpressure control system of a supper-pressure pump for a cubic press, which comprises the supper-pressure pump. Two super-pressure pilot-operated check valves are parallelly connected to an oil outlet pipeline of the super-pressure pump, are respectively connected with two cubic presses and respectively connected with two electromagnetic reversing valves. The two cubic presses share the same super-pressure pump and one super-pressure pump is omitted so that input cost for equipment is reduced greatly, and meanwhile, the super-pressure pump can be used sufficiently so that utilization rate of equipment is increased greatly.
Description
Technical field
The utility model relates to a kind of cubic hinge press super-pressure pump superpressure control system.
Background technology
Cubic hinge press is the special equipment that diamond is produced, and existing cubic pressure machine hydraulic system superpressure mode is: super-pressure pump of a press configuration; And super-pressure pump a synthetic piece from the superpressure to the backhaul in the whole process the used time be no more than 3 minutes, the super-pressure pump price is high, a press is joined a super-pressure pump has not only increased equipment investment, and the utilization rate of super-pressure pump is not high.
The utility model content
The purpose of this utility model provides the cubic hinge press super-pressure pump superpressure control system that a kind of equipment investment is little, utilization rate is high.
For achieving the above object, the technical solution adopted in the utility model is:
Cubic hinge press comprises super-pressure pump with super-pressure pump superpressure control system, is connected in parallel to two super-pressure hydraulic control one-way valves on the fuel-displaced pipeline of super-pressure pump, and two super-pressure hydraulic control one-way valves are connected with two cubic hinge press respectively; Be connected with solenoid directional control valve respectively on two super-pressure hydraulic control one-way valves.
All be serially connected with check valve between described super-pressure hydraulic control one-way valve and the cubic hinge press.
The utility model adopts two shared super-pressure pumps of cubic hinge press, has saved a super-pressure pump, greatly reduces the input cost of equipment; Simultaneously, a super-pressure pump is fully used, improved utilization rate of equipment and installations greatly.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, cubic hinge press super-pressure pump superpressure control system, comprise super-pressure pump 1, be connected in parallel to super-pressure hydraulic control one-way valve 3-1,3-2 on the super-pressure pump 1 fuel-displaced pipeline, super-pressure hydraulic control one-way valve 3-1,3-2 are connected with cubic hinge press 5-1,5-2 respectively; Be connected with solenoid directional control valve 2-1,2-2 respectively on super-pressure hydraulic control one-way valve 3-1, the 3-2.Be serially connected with check valve 4-1 between described super-pressure hydraulic control one-way valve 3-1 and the cubic hinge press 5-1, be serially connected with check valve 4-2 between super-pressure hydraulic control one-way valve 3-2 and the cubic hinge press 5-2.
When the utility model uses, when cubic hinge press 5-1 needs superpressure, solenoid directional control valve 2-1 is charged, control oil is opened super-pressure hydraulic control one-way valve 3-1 through solenoid directional control valve 2-1, super-pressure pump 1 starts, fluid flows to cubic hinge press 5-1 by check valve 4-1, and this moment, super-pressure hydraulic control one-way valve 3-2 was in closure state, and fluid can not flow to cubic hinge press 5-2; When cubic hinge press 5-2 needs superpressure, solenoid directional control valve 2-2 is charged, control oil is opened super-pressure hydraulic control one-way valve 3-2 through solenoid directional control valve 2-2, super-pressure pump 1 starts, fluid flows to cubic hinge press 5-2 by check valve 4-2, this moment, super-pressure hydraulic control one-way valve 3-1 was in closure state, and fluid can not flow to cubic hinge press 5-1.
Claims (2)
