Description

Inclined disc type axial work-plunger displacement pump that fluid energy reclaims can be realized
Technical field
The present invention relates to technical field of energy recovery, particularly relate to a kind of inclined disc type axle realizing fluid energy recovery To work-plunger displacement pump.
Background technology
Along with the development of society, people are more and more higher to the pursuit of capacity usage ratio.Lead in the commercial production relating to fluid Territory, it is common that utilize fluid pump produce high-pressure fluid to drive actuator work, and the most often generation contain Having the disposal fluids of certain pressure, these can cause energy dissipation containing the discarded of baric flow body, causes the Energy harvesting of system Rate is low.Such as in reverse osmosis seawater desalting engineering, the former water of high pressure can produce fresh water and high pressure after reverse osmosis unit Concentrated seawater, wherein there are about the feed pressure energy of 60% in high-pressure thick sea water, directly discharge will result in huge energy dissipation, and Concentrated seawater can not directly mix with former water again, and the most how reclaiming this portion of energy is to improve whole system capacity usage ratio Key.
For the energy of Appropriate application disposal fluids, various forms of energy recycle devices occur in succession.But existing energy returns Receiving apparatus still has the disadvantage that 1) there is intermediate link in energy regenerating, causes the secondary of energy to be wasted;2) energy recovery process The middle mixing that there is high-pressure exhaust fluid and low pressure material flow, causes the pollution of material flow;3) device is complicated, and parts are numerous Many and higher to control system requirement, add cost of investment.
Summary of the invention
For the defect overcoming prior art to exist, the present invention provides one can reduce energy transmission link, segmentation is discarded Fluid can realize, with material flow and simple in construction, inclined disc type axial work-plunger displacement pump that fluid energy reclaims.
For achieving the above object, have employed techniques below scheme:
A kind of inclined disc type axial work-plunger displacement pump realizing fluid energy recovery, its main parts size includes the pump housing, end Lid, swash plate, return plate, central spring assembly, cylinder body, work-plunger, valve plate and pump shaft.The described pump housing include the front pump housing and after The pump housing;Described end cap includes drive end bearing bracket and rear end cap;Described swash plate is placed in the groove of rear end cap and is entered by the first alignment pin Row is fixing, and swash surfaces forms an angle with cylinder body axis, and this corner dimension affects the discharge capacity of each chamber of cylinder body;Described valve plate Being two Split type structures, including the first valve plate, the second valve plate, first, second valve plate is positioned by second, third respectively Pin is fixed on the front pump housing;Described cylinder body is tightly placed on pump shaft by spline, is placed between swash plate and valve plate, and cylinder body is outside logical Cross clutch shaft bearing to be supported in the rear pump housing;Described cylinder body is step-like distribution with the contact surface of valve plate, the ring shaped contact of cylinder body Face is in close contact with the first valve plate, forms the first Port Plate Pair, and the circular contact face of cylinder body and the second valve plate are in close contact, shape Become the second Port Plate Pair;Circumferentially being uniformly arranged some cylinder holes in cylinder body, each cylinder holes is respectively provided with corresponding fluid passage, in cylinder holes Work-the plunger of respective numbers is set, forms different chamber and connect with corresponding fluid passage;Described work-plunger external part is hinged There are piston shoes, and piston shoes are close on swash plate by return plate effect;It is provided with in the middle part of described return plate and matches with central spring assembly The concave spherical surface closed;Described central spring assembly includes that steel ball, inner sleeve, central spring and overcoat, central spring assembly pass through overcoat It is arranged in pump shaft, is connected with return plate by steel ball;Described pump shaft by the second bearings in front pump body, in front pump body Being provided with fluid intake corresponding with described fluid passage and outlet, front pump external body is connected with drive end bearing bracket.
