Abstract
The utility model discloses a high-performance remote automatic control axial plunger pump which comprises an oil cylinder, a variable plunger pump, an oil pipe, a proportional pressure shut-off valve, a safety pressure shut-off valve, a branch pipe, an oil supply pipe and an oil drain pipe; the oil inlet end of a solenoid-operated valve for receiving electrical control signals is connected with the right end of the proportional pressure shut-off valve; the solenoid-operated valve is communicated with an oil drain port of the variable plunger pump through the oil drain pipe; the connecting branch pipe is arranged between the oil supply pipe and the oil inlet end of the solenoid-operated valve; a damping screw is arranged on the connecting branch pipe; and the oil inlet end of the solenoid-operated valve is connected with a feedback signal interface for receiving system pressure control signals. Compared with the safety overflow valve on the hydraulic system, the high-performance remote automatic control axial plunger pump with reasonable structure is free from spill loss and is more energy-saving.
Description
Technical field:
The utility model relates to a kind of axial piston pump.
Background technique:
Existing plunger pump does not have safety pressure cut-out, the automatically controlled functions such as the pressure cut off of plunger pump, the control of awaiting orders that realize, service behaviour is undesirable.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the high-performance remote auto control axial piston pump of favorable working performance.
Technical solution of the present utility model is:
A kind of high-performance remote auto control axial piston pump, it is characterized in that: comprise the Variable plunger pump that communicates with oil cylinder, the oil supply port of Variable plunger pump is by rail and ratio pressure cut-off valve, the left end of safety pressure cut-off valve connects, the ratio pressure cut-off valve, the right side oil pocket of safety pressure cut-off valve is connected with rail by arm, the ratio pressure cut-off valve, the safety pressure cut-off valve communicates with the drain tap of Variable plunger pump by drain mast, rail is provided with oil outlet, the left chamber of the piston cylinder of Variable plunger pump is connected with rail and safety pressure cut-off valve respectively, the ratio pressure cut-off valve communicates with the oil pocket of safety pressure cut-off valve, an oil inlet end that receives the solenoid electric valve of automatically controlled signal is connected with the right-hand member of ratio pressure cut-off valve, solenoid electric valve communicates with the drain tap of Variable plunger pump by drain mast, between the oil inlet end of rail and solenoid electric valve, connecting branch is set, and on this connecting branch the damping screw is set; The oil inlet end of solenoid electric valve is connected with the feedback signal interface of receiving system pressure controling signal.
The utility model is rational in infrastructure, and plunger pump can need by system when a certain operating mode, is operated in arbitrary control mode of electric-hydraulic proportion pressure cut off, safety pressure cut-out, the control of awaiting orders; The priority of control is for the control of awaiting orders, electro-hydraulic pressure cut off, safety pressure cuts off; The control that realizes awaiting orders of the pressure controling signal of feedback signal interface (X mouth) receiving system by pressure shut-off valve, when awaiting orders control, system is near zero pressure, zero delivery running, energy saving when making system unloaded; The control of the ratio pressure cut-off valve on the pump is realized the electric-hydraulic proportion pressure cut off function of plunger pump by automatically controlled signal, make system in the work cycle process, change the pressure cut off point arbitrarily, thereby make hydraulic system realize long-range and automation control from the hydraulic power end according to operating mode; By the pressure cut off function, can make system load reach setting pressure after, the output flow that reduces pump is required to keeping system, least energy consumption when realizing working state.By the safety pressure cut-off valve, can set the highest system pressure, prevent system overload, compare the safety overflow valve on the hydraulic system, no spill losses, more energy-conservation.
