Abstract
The present invention relates to a multipurpose hydraulic transmission piston pump which is composed of a pump body and an oil passage control system, and has the characteristics of simple structure, high efficiency, low cost, low noise, steady and safe transmission, high delivery lift (suction lift), low oil consumption, very obvious electricity saving effect, etc. The present invention can be used for air compressors, air hammers, water pumps, vacuum pumps, blowers, super high pressure oil pumps, dust suction, granular object transmission, etc.
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.
Existing hydraulic transmission piston pump, complex structure is made the processing and debugging difficulty, and it is unreliable to commutate.As U. S. Patent 4390322, a kind of detail structure and working principle of hydraudynamic drive gas compressor once disclosed.This machine is a kind of multiple cylinder multiple level double action gas compressor that promotes with fluid power.Its main machine structure is that pump housing partial design is comparatively reasonable, but the used element of reversing mechanism is more, and structure is too complicated.Thereby make, assembling, debug difficulties.Even qualified, after the compressor proper functioning, also very easily break down at assembling and setting.Therefore complete machine will be seriously influenced working life.
The objective of the invention is to overcome the existing defective of above-mentioned hydraudynamic drive gas compressor, and a kind of multipurpose fluid drive piston pump of design.Have simple in structurely, easy to manufacture, processing cost is low, and it is safe and reliable to commutate, characteristics such as long service life.This machine can replace bent axle or eccentric wheel transmission.Be used for air compressor, refrigerating machine, air separation equipment, vacuum pump, slurry pump, diaphragm pump, pumping unit, deep-well oil pump, superpressure oil pump, gas pump, gas pump, natural air pump etc. need the power equipment of linear reciprocating motion.
The present invention mainly is made of the pump housing and oil path control system two-part.Pump housing part is mainly by oil cylinder, clutch release slave cylinder, oil cylinder piston, slave cylinder piston, and piston rod and suction, exhaust (liquid) valve constitute.Oil cylinder piston, slave cylinder piston and piston rod is coaxial links to each other.During work, when oil cylinder piston and coaxial continuous slave cylinder piston to-and-fro motion, make clutch release slave cylinder produce the function of suction, exhaust (liquid), thereby reach the purpose of acting.Pump housing part can adopt multi-cylinder double action structure and twin-tub dual-piston structure, also can adopt the two diaphragm pump structure.In the two diaphragm pump structure, barrier film is the piston of this pump, and by piston rod two diaphragms is linked to each other, and makes its interlock.
Oil path control system mainly is made of motor, oil pump, the non-adjustable two-position four way change valve that surges, two normally closed Twoway valvess, spill valve, oil cleaner screen and fuel tanks.Wherein, two position two-way valve is positioned among the end cap of oil cylinder both sides, and is formed by connecting with oil cylinder and is one; Guiding valve is that spool and piston rod are formed by connecting and are one.In the twin-tub double-piston pump housing and the two diaphragm pump pump housing, all be positioned at centre one side of two cylinders owing to two Twoway valves valve bodies.So two Twoway valves valve bodies can be formed a two-position three way valve body.The structure of spool is identical during still with the multi-cylinder pump housing.About driving medium, can use hydraulic oil, also can select emulsified liquid and water for use.So kinetic pump can be selected emulsion pump and water pump for use.
The concrete structure of invention is provided by following embodiment and accompanying drawing thereof.
Accompanying drawing is according to the structure principle chart of the present invention's designed " multipurpose fluid drive piston pump ".
(1) to be slave cylinder piston, (2) be fuel tank for motor, (13) for oil cleaner screen, (14) for oil pump, (12) for spill valve, (11) for the non-adjustable two-position four way change valve that surges, (10) for air-breathing (liquid) valve, (9) for exhaust (liquid) valve, (8) for Twoway valves valve body and end cap, (7) for oil cylinder piston, (6) for piston rod and Twoway valves spool, (5) for oil cylinder, (4) for clutch release slave cylinder, (3) among the figure.
CONSTRUCTED SPECIFICATION and working condition below in conjunction with description of drawings " multipurpose fluid drive piston pump ".
Work as electric motor starting, during oil pump work, pressure oil self-commutation valve PB enters the right chamber of oil cylinder, and the oily self-commutation valve AO in left chamber flows back to fuel tank.Oil cylinder piston and coaxial continuous slave cylinder piston are to left movement.At this moment, the right chamber of two clutch release slave cylinders air-breathing (liquid), left chamber exhaust (liquid), when the left end limit position was arrived in piston motion, the Twoway valves of left end was connected, and pressure oil enters in the liquid controling cavity of selector valve.Under the effect of pressure oil, change-over valve core is transported to the right.The selector valve commutation.Oil cylinder piston and coaxial continuous slave cylinder piston move right.At this moment, the left chamber of two clutch release slave cylinders air-breathing (liquid), right chamber exhaust (liquid).When extreme right position was arrived in piston motion, the Twoway valves of right-hand member was connected, and the oil of selector valve liquid controling cavity flows back to fuel tank.Under the effect of spring, change-over valve core is got back to left position, the selector valve commutation, and piston is again to left movement.Like this, go round and begin again, constantly move back and forth, thereby reach the purpose of acting.
Claims (1)
1, a kind of multipurpose fluid drive piston pump, belong to the hydraudynamic drive technical field, mainly form by the pump housing and oil path control system two-part, it is characterized in that two position two-way valve or two position three-way valve in the oil path control system are positioned among the end cap of oil cylinder both sides, and be formed by connecting with oil cylinder and be that one, spool are that guiding valve and piston rod are formed by connecting and are one.
