Background technique
In the design of electrical system process of lathe, usually run into the control requirement of hydraulic system pressurize, the function of pressure dwelling loop is to make system load motionless or produce because of workpiece deformation under the operating mode of micro-displacement and can keep stablizing constant pressure at oil hydraulic cylinder, and make oil hydraulic pump in unloading condition. two leading indicators of pressure maintaining performance are dwell time and pressure stability, initial control mode is that motor drives oil pump oil supply oil supply cylinder, reach rated pressure value, use nut check pressurize, then disable motor, operate more loaded down with trivial details, and in the time unclamping, tending to occur forgetting that tightening nut just operates release button, the phenomenon such as cause that piston comes off, affect working efficiency, use inconvenient.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of automatic pressure-maintaining control system simple in structure, easy to use.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: automatic pressure-maintaining control system, comprise motor, be connected to the some A.C. contactors on motor, be connected to the battery main switch on A.C. contactor, be connected to the A.C. contactor on battery main switch, be connected to the some auxiliary reclays that are arranged in parallel on A.C. contactor, be connected to the battery valve on A.C. contactor, the first loop apparatus being arranged in parallel with battery valve, the second servo loop device being arranged in parallel with the first loop apparatus, the button groups being arranged in parallel with second servo loop device, on described A.C. contactor, be connected with fus.
As preferably, described the first loop apparatus is made up of some signaling lamps and auxiliary reclay, observes the working condition on circuit by signaling lamp.
As preferably, described second servo loop device is made up of pressure gauge and auxiliary reclay, by the pressure index in pressure gauge testing circuit.
As preferably, described button groups comprises stop button, compresses button and loosen button, wherein compresses button and forms loop apparatus with auxiliary reclay respectively with loosening button, by button groups, the energising situation of circuit is controlled.
As preferably, on described battery main switch, connect toggle switch, be provided with toggle switch volume little, easy to operate.
As preferably, on described battery valve, be connected with auxiliary reclay, by auxiliary reclay, battery valve is protected.
As preferably, described pressure gauge is pressure gauge with electric contact, pressure gauge with electric contact reliable in action, and long service life, contact switch power is large.
Beneficial effect:
The utility model has adopted technique scheme that automatic pressure-maintaining control system is provided, and has made up the deficiencies in the prior art, reasonable in design, sound construction, and reliable operation, working efficiency is high, easy to operate, reduces potential safety hazard, uses safety.
