Description
The invention belongs to the hydraudynamic drive technical field.More precisely, be a kind of power plant that promote piston linear reciprocating motion with fluid power.Can replace bent axle or eccentric wheel transmission.Can be used for air compressor, refrigerating machine, air separation plant, vacuum pump, slurry pump, diaphragm pump, pumping unit, superpressure oil pump, gas pump, gas pump, natural air pump etc. needs the power equipment of linear reciprocating motion.
The present invention is improving of patent application 86101588 and 86206322 and development.In above-mentioned two applications, because the structure of oil cylinder is comparatively complicated, volume is big.Therefore processing is relatively more difficult, is prone to fault during work, and also be affected working life.The objective of the invention is to overcome the defective that is occurred in twice application, and solved lubricated, the cooling problem.Have simple in structure, easy processing, the efficient height, cost is low, characteristics such as long service life.
This pump mainly is made up of the pump housing, liquid controlled reversing system, lubrication system, cooling system four parts.
Pump housing part mainly is made of power cylinder and clutch release slave cylinder.Each can drive one or more clutch release slave cylinders to it is characterized in that the power cylinder two ends, and clutch release slave cylinder can adopt single action or double action structure.During work, oil cylinder piston drives the slave cylinder piston of coaxial connection, carries out linear reciprocating motion, makes clutch release slave cylinder produce the function of suction, exhaust (liquid), thereby carries out work.Pump housing part also can adopt the structure of a cylinder and two chambers.
The liquid controlled reversing system is mainly by the two-position four way change valve that surges, two Twoway valvess, and two fluid-control one-ways constitute.It is characterized in that the Twoway valves valve body is positioned among the end cap of oil cylinder both sides, and be formed by connecting with oil cylinder and be one.Guiding valve is that spool and piston rod are formed by connecting and are one.During work, when cylinder piston motion arrived extreme right position, the Twoway valves of right-hand member was connected, pressure oil enters the left chamber of selector valve and the liquid controling cavity of Pilot operated check valve I, and the oil in the right chamber of selector valve is through Pilot operated check valve I refluence oil sump tank, and spool moves right, the selector valve commutation, piston is to left movement.When the left end limit position is arrived in piston motion, the Twoway valves of left end is connected, pressure oil enters the liquid controling cavity of right chamber of selector valve and Pilot operated check valve II, the oil in chamber, a selector valve left side is refunded fuel tank through the Pilot operated check valve II, spool is to left movement, the selector valve commutation, piston moves right, and has begun new stroke again.The structural principle of reversing mechanism of the present invention also is applicable to the pump housing of twin-tub dual-piston structure.Cylinder structure of the present invention also can be used for the program control oil cylinder.
Lubrication system is by oil cylinder piston, slave cylinder piston, and piston rod and one-way valve constitute.It is characterized in that, oil cylinder piston, slave cylinder piston, piston rod is cavity, three's intercommunication.Be drilled with oilhole between oil cylinder piston and the clutch release slave cylinder two-piston ring, one-way valve is contained in the oil cylinder piston both sides.During work, pressure oil is by one-way valve, and oilhole enters between the two-piston ring, and the cylinder face is lubricated, this kind lubricating structure, and not only high lubricating effect has also played the effect of hydrodynamic journal liquid polymers and sealing simultaneously.
The cooling system of this pump can adopt the water-cooled and the air cooling way of common air compressor, also can adopt the interior type of cooling.It is characterized in that clutch release slave cylinder partly adopts the single action structure.And be provided with water pipe adapter at two slave cylinder piston non-working side cylinder body end faces, make it to communicate with cooling water tank and clutch release slave cylinder cylinder interior.When the slave cylinder piston exhaust, cooling water promptly is inhaled in the clutch release slave cylinder by water pipe, and when clutch release slave cylinder was air-breathing, cooling water was flow back to water tank by water pipe again.
About fed sheet of a media, can select for use oil, emulsified liquid, water and other liquid as carrying driving medium, also can select for use steam and pressurized gas as carrying driving medium.About kinetic pump, can select various oil pumps and emulsion pump for use, also can select clean waterpump for use.If select emulsion pump and clean waterpump for use, then can integrate transmission, lubricate, cool off, make its structure simpler.In order to reduce volume, all hydraulic element in this pump liquid controlled reversing system can be designed to manifold type, also can be overlapping.
The concrete structure of invention is provided by following embodiment and accompanying drawing thereof.
Accompanying drawing is according to principle of the present invention, the structure principle chart of designed a kind of interior cooling type hydraudynamic drive gas compressor.This machine also can use as vacuum pump simultaneously.(1) is outlet valve among the figure, (2) be clutch release slave cylinder, (3) are Aspirating valves, and (4) are oilhole, (5) be the cooling water interface, (6) be slave cylinder piston, (7) are the Twoway valves valve body, and (8) are Twoway valves spool and piston rod, (9) be piston ring, (10) be oil cylinder piston, (11) are one-way valve, and (12) are piston ring, (13) be the two-position four way change valve that surges, (14) be spill valve, (15) are oil pump, and (16) are motor, (17) be oil cleaner screen, (18) be fuel tank, (19) are Pilot operated check valve, and (20) are seal ring.
Describe the CONSTRUCTED SPECIFICATION and the working condition of this compressor in detail below in conjunction with accompanying drawing.
As shown in drawings.Work as motor start-up, when oil pump was started working, piston moved right.At this moment the left chamber of left slave cylinder piston is air-breathing, right chamber row's cooling liquid.The right chamber exhaust of right slave cylinder piston, cooling liquid is inhaled in left chamber.When extreme right position was arrived in piston motion, the Twoway valves of right-hand member was connected.Pressure oil enters the left chamber of selector valve and the liquid controling cavity of Pilot operated check valve I, and the oil in the right chamber of selector valve is through Pilot operated check valve I refluence oil sump tank.Change-over valve core moves right, the selector valve commutation, and piston is moved to the left.At this moment, the right chamber of right slave cylinder piston is air-breathing, left chamber row's cooling liquid.The left chamber exhaust of left side slave cylinder piston, cooling liquid is inhaled in right chamber.When the left end limit position was arrived in piston motion, the Twoway valves of left end was connected.Pressure oil enters the liquid controling cavity of right chamber of selector valve and Pilot operated check valve II, and the oil in chamber, a selector valve left side is through Pilot operated check valve II refluence oil sump tank, and change-over valve core is moved to the left, the selector valve commutation.Piston moves right, and has begun new stroke again.When compressor operating, no matter to which direction motion, pressure oil is through oil cylinder piston both sides one-way valve and oilhole, enters between the two-piston ring and to the cylinder face to be lubricated.This kind lubricating structure has also played the effect of hydrodynamic journal liquid polymers and sealing, and the pressurized gas in two chambeies can not be flowed mutually.Be noted that in addition: in the time of the clutch release slave cylinder exhaust, cooling liquid promptly is inhaled in the cylinder, and the cylinder face is cooled off.When clutch release slave cylinder was air-breathing, cooling liquid was flow back to tank for coolant again.
