Abstract
The present invention relates to an energy-saving superhigh-pressure gas (liquid) output device, more specifically to a superhigh-pressure gas (liquid) output device for hydraulic transmission, which is mainly composed of a low-pressure system, a high-pressure system, an automatic switching control system and a pumping station. The superhigh-pressure gas (liquid) output device outputs gas (liquid) at a high flow rate under low pressure and outputs gas (liquid) at a low flow rate under high pressure. The present invention can be used for power equipment needing to output gas (liquid) with high pressure or superhigh pressure, for example emulsion pumps, pressurized water-injection pumps, superhigh-pressure pumps, superhigh-pressure gas compressors, etc.
Description
The invention belongs to pump series products and gas compressor product technical field.More particularly, be a kind of with hydraulic pressure or the pump of air pressure driving and the automatic reverse system of gas compressor.
The present invention is improving of patent of invention 86101588.6, CN86106341A and 881041.5 and development.Above-mentioned three applications for a patent for invention all are to adopt Twoway valves valve body and cylinder cover to be combined as a whole the agent structure that spool and piston rod are combined as a whole.Different is to control in the reversing oil circuit selected hydraulic element difference automatically.In 86101588.6 applications for a patent for invention, its working principle is, when piston rod movement during to an end limit position, Twoway valves is worked hard in glove with, two-position four-way Y type hydraulicchange-over valve feed liquor, selector valve commutation.When piston reverses direction moved to the other end limit position, the other end Twoway valves was worked hard in glove with, the pressurised fluid stream oil sump tank in the selector valve liquid controling cavity, and under the effect of spring, the selector valve commutation that resets.The major defect of patent of invention 86101588.6 is, because the spring of two-position four-way Y type hydraulicchange-over valve is difficult to remain centering, in the process of commutation, through regular meeting spring takes place and blocks and can not reset, thereby make the malfunctioning phenomenon of commutation.In the CN86106341A application for a patent for invention, its working principle is, when piston rod movement during to an end limit position, oil circuit is worked hard in glove with.Adjusting throttle valve commutates; When piston reverses direction moves to the other end limit position, also adjust with same method; Adjustment through repeated multiple times just can make its work.The major defect of patent of invention CN86106341A is, complex structure, selects that hydraulic element are many, manufacture cost is high, control oil channel does not constitute the loop for use, big, the debug difficulties of power consumption during commutation, not easy to operate and grasp.Because two liquid controling cavities of guide's hydraulicchange-over valve communicate with fuel tank by throttle valve, thus two problems inevitably appear, one be turn around time long, consume energy big, insensitive, unreliable; Another problem is after piston leaves limit position, because two liquid controling cavities of guide's hydraulicchange-over valve communicate with fuel tank by throttle valve, so there is not pressure, then spool is in free state.At this moment, place injustice or through after the strong vibration, guide's hydraulicchange-over valve spool is moved as valve body, therefore chaotic malfunctioning phenomenon also can take place in whole reversing mechanism.In 88104181.5 applications for a patent for invention, its working principle is, when piston rod movement during to an end limit position, oil circuit is worked hard in glove with.Pressure liquid enters an end of hydraulicchange-over valve and the liquid controling cavity of Pilot operated check valve.And the pressure liquid of the hydraulicchange-over valve the other end is by the one-way valve oil sump tank that flows backwards, and the hydraulicchange-over valve commutation when piston reverses direction moves to the other end limit position, also commutates with same principle.The major defect of patent of invention 881041815 is, complex structure, manufacture cost height, generation sometimes in commutation process, Pilot operated check valve is after finishing commutation process, can not close, when carrying out next program commutation, pressured fluid moves so can not promote the hydraulicchange-over valve spool, thereby makes whole reversing mechanism malfunctioning through the Pilot operated check valve oil sump tank that flows backwards.
Purpose of the present invention is exactly in order to overcome the above-mentioned defective of patent of invention 86101588.6, CN86106341A and 88104181.5.Provide a kind of simple in structure, cost is low, power consumption is little, sensitive reversing, pump safe and reliable, that drive with hydraulic pressure or air pressure and the automatic reverse system of gas compressor.Can be used for various with pressured fluid or the pump series products, gas compressor product and the pressurized machine product that drive with pressed gas.
The present invention mainly by motor, kinetic pump, ram, surge or air operated reversing valve is constituted: it is characterized in that; (1) respectively is drilled with a, b, c, d and e, f, g, four radial holes of h or a, b, c and e, three radial holes of f, g on two four-way valve bodies that are combined as a whole with the ram two end cap or the two threeway valve bodies.(2) four-way valve spool in the system or three-way valve spool and piston rod are combined as a whole.
The concrete structure of invention is provided by following embodiment Fig. 1 and Fig. 2.
Fig. 1 is that two end cap is four-way valve body, the fundamental diagram when using hydraulic driving, (1) end cap and four-way valve body, (2) piston, (3) piston rod and four-way valve spool, (4) ram, (5) hydraulicchange-over valve, (6) liquid case, (7) kinetic pump (8) motor, (9) filtrate net, (10) relief valve among the figure; A, b, c, d, e, f, gh are joint.
Two end cap is three-way valve valve body, the fundamental diagram when using hydraulic driving among Fig. 2, (1) end cap and three-way valve valve body, (2) piston, (3) piston rod and three-way valve spool, (4) ram, (5) hydraulicchange-over valve, (6) liquid case, (7) kinetic pump, (8) motor, (9) filtrate net, (10) relief valve among the figure; A, b, c, e, f, g are joint.
Describe the CONSTRUCTED SPECIFICATION and the working condition of the automatic reverse system of the hydraulically powered pump of a kind of usefulness and gas compressor and pressurized machine in detail below in conjunction with Fig. 1 and Fig. 2.
As shown in Figure 1, when motor (8) startup, during kinetic pump (7) work, piston (2) moves right, when piston (2) when moving to extreme right position, e, f connect, and g, h connect, selector valve (5) left end feed liquor, right-hand member discharge opeing, selector valve (5) valve core movement arrives right end position, and begins commutation.At this moment, piston (2) is to left movement, when piston (2) moves to the left end limit position, and a, b, connection, c, d connect, selector valve (5) right-hand member feed liquor, left end discharge opeing, selector valve (5) valve core movement is to left position, and commutates.Begin new stroke again.
As shown in Figure 2, when motor (8) starts, during kinetic pump (7) work, piston (2) moves right, and when piston (2) when moving to extreme right position, a, b connect, and e, f connect; Selector valve (5) left end feed liquor, right-hand member discharge opeing, selector valve (5) valve core movement arrives right end position, and begins commutation.At this moment, piston (2) is to left movement, and when piston (2) moved to the left end limit position, b, c connected, and g, f connect, selector valve (5) right-hand member feed liquor, left end discharge opeing, and selector valve (5) valve core movement is to left position, and commutates.Begin new stroke again.
Working principle when the present invention drives with air pressure, the working principle during with hydraulic driving is identical, so outline.
