Embodiment Construction
[0016] Such as figure 2 , image 3 As shown, this embodiment includes a plunger cylinder 13, a high-pressure oil pump 14, an oil tank 15, a balance accumulator tank 16, and a hydraulic lift control valve. The hydraulic lift control valve includes a one-way valve A, a one-way valve B, and unloading The device, the electromagnet 11, the overflow valve 12 and the valve body 7, the one-way valve A, the one-way valve B, the unloading device, the electromagnet 11 and the overflow valve 12 are assembled on the valve body 7.
[0017] The non-return side of the one-way valve A and the one-way valve B are connected to become the oil outlet C of the hydraulic lift control valve. The oil outlet C is connected to the oil inlet of the plunger cylinder 13 and the balance storage tank 16 The inlet of the one-way valve A is the oil inlet E of the hydraulic lift control valve, the oil inlet E is connected to the output of the high-pressure oil pump 14, and the inlet of the one-way valve B is the ...

The invention relates to plunger case control technology, in particular to a plunger case lifting hydraulic control system, which comprises a plunger case, a high pressure oil pump, an oil tank, a balanced energy storage tank and a hydraulic lifting control valve, wherein the hydraulic lifting control valve comprises a check valve A, a check valve B and an electromagnet; the check sides of the check valve A and the check valve B are connected and are connected with the oil inlet of a plunger case and the balanced energy storage tank; the inlet of the check valve A is connected with the outputend of the high pressure oil pump; a valve plug of the check valve B supports on a mandril of the electromagnet; and the inlet of the check valve B is communicated with the oil tank through a pipeline. The invention aims to design a plunger case lifting hydraulic control system capable of reducing manufacturing cost, reducing installation volume and improving the sensitivity of control action. Compared with the prior art, the plunger case lifting hydraulic control system has the advantages of flexible installation, safe and convenient operation in the power-off state, particular suitability for occasions with limited installation spaces, convenience in manufacturing and maintaining the control system and the like.
Description
Technical field [0001] The invention relates to a plunger cylinder control technology, in particular to a plunger cylinder lifting hydraulic control system. Background technique [0002] With the improvement of industrialization, plunger cylinders are widely used in various fields, such as hydraulic presses, hydraulic lifts, engineering machinery manipulators, lifting devices, etc., and the hydraulic systems that control their rise and fall are also rich and diverse, but regardless of How often the control system requires several mature hydraulic valves. [0003] Existing typical control systems that control the lift of the plunger cylinder are such as figure 1 As shown, it is mainly composed of reversing valve, pressure maintaining valve, overflow valve, hydraulic control one-way valve and valve body integrated block. The system uses common hydraulic control check valve and independent check valve to realize the lifting and pressure maintaining of the plunger cylinder. Therefore...
