Description

The vane pump of sealed type
Technical field
The present invention relates to vane pump field, particularly the vane pump of sealed type.
Background technique
Vane pump is that the blade in rotor contacts with pump case, by the liquid of suction by the pump of oil-feed side pressure to oil extraction side.Pump is made up of parts such as rotor, stator, blade, oil distribution casing and end caps.The internal surface of stator is cylindrical hole, there is bias between rotor and stator.Blade can easy slide in the groove of rotor, centrifugal force when rotor turns and pass into root of blade pressure oil effect under, vane tip is adjacent on stator inner surface, so just define the active chamber sealed one by one between two adjacent blades, oil distribution casing, stators and rotators.When rotor is by when counterclockwise rotating, the blade at filler opening place is protruding, and pressurization working lumen volume increases gradually, produces vacuum, so sucked by oil by window on inlet port and oil distribution casing.The blade indentation inward at oil outlet place, the volume of Seal cage reduces gradually, and the fluid in Seal cage is forced out through another window of oil distribution casing and force feed mouth and outputs in system and goes.This pump is gone around in process at rotor, and oil suction force feed is each once, therefore claims single-acting pump.Rotor is subject to hydraulic radial influence of unbalance power, therefore also known as unbalanced pump, its bearing load is larger.
Special in Motor Vehicle, such vane pump is used for engine oil or gear box oil with the form of oil pressure pump.Pump or its rotor by motor, especially by internal combustion engine drive, especially by its camshaft actuated.Vane pump has half moon-shaped pressure chamber usually, and it is divided into pressure chamber by least one blade.The rotation of the rotor arranged by the inwall being eccentric in adjustment housings, can provide Pressure Drop between absorption entrance and pressure export.Aforesaid vane pump is adjustable or variable; By regulating adjustment housings, the size of half moon-shaped pressure chamber can be regulated; Have also been changed pump characteristics thus.Therefore the power of vane pump can be set according to demand.For such vane pump, must guarantee that vane pump has the structure sealed as far as possible, but present vane pump and oil inlet pipe, oil outlet tube are all bolted, there will be gas leak phenomenon, and vane pump just must can carry out oil suction and oil extraction under vacuum condition, for this reason, vane pump can be caused so normally to work or oil sucting force inadequate.General cover has sealing gasket for sealing now, but sealing gasket Long-Time Service, and sealing effect can reduce.
Summary of the invention
The object of this invention is to provide the vane pump of sealed type, make the sealing effect of vane pump better, there will not be gas leak phenomenon, ensure the normal work of vane pump.
The invention provides a kind of base case: the vane pump of sealed type, it is used as fluid pressure supply source, and this vane pump comprises: rotor, and it is rotated by driving; Multiple blade, it is accommodated in above-mentioned rotor in the mode slid freely; Stator, it has the inner circumferential camming surface of the tip portion sliding contact for above-mentioned blade, and can be eccentric relative to the center of above-mentioned rotor; Pump chamber, its division is formed between above-mentioned rotor, said stator and adjacent above-mentioned blade; Suction port, it is for guiding the working fluid be inhaled in above-mentioned pump chamber; And exhaust port, it is for guiding the working fluid of discharging from above-mentioned pump chamber; Oil inlet pipe is provided with above suction port, suction port is fixedly connected with oil inlet pipe, oil outlet tube is provided with above exhaust port, exhaust port is fixedly connected with oil outlet tube, seal ring is arranged with outside suction port and exhaust port, offer expansion chamber in seal ring, above seal ring, be provided with the inlet hole that to be connected with expansion chamber.
Working principle and beneficial effect are: the present invention adopts the air in vane pump to be full of expansion chamber, and make it be propped up by seal ring, thus suction port and oil inlet pipe can seal completely, meanwhile, exhaust port and oil outlet tube can seal completely.So mainly because vane pump generally just can carry out oil suction and oil extraction under vacuum condition, and present most mode is for pouring water discharge air, also has one to be carry out air-breathing with suction means.And expansion chamber is mainly by for collecting the air in vane pump, makes seal ring automatic expansion, thus suction port and exhaust port are fitted completely with the internal surface of oil inlet pipe and oil outlet tube respectively, ensure that the sealing of vane pump.Utilize own resource like this, make air in vane pump become the medium of sealing from harm, structure is simple, saving resource.
Further optimized project one for base case: seal ring is circular.The seal ring of toroidal in use can not roll, and so just can ensure that the inlet hole on seal ring is connected with oil inlet pipe and oil outlet tube all the time.
Further optimized project two for base case: blade lower end surface is provided with wearing layer.Because blade and rotor are slidably connected, can produce friction between the lower end surface of blade and rotor, wearing and tearing blade, for this reason, arranges blade lower end surface and is provided with wearing layer, can improve the working life of blade.
Further optimized project three for base case: the top of blade is arranged with elastic sleeve, so that the surface of rotor is touched at the top of blade, can not produce wearing and tearing.
Further optimized project four for base case: suction port and oil inlet pipe are bolted to connection.Like this can so that fixing and dismounting.
Further optimized project five for base case: exhaust port and oil outlet tube are bolted to connection.Like this can so that fixing and dismounting.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is structural representation of the present invention.
Embodiment
Mark in accompanying drawing of the present invention is: rotor 1, blade 2, stator 3, suction port 4, exhaust port 5, oil inlet pipe 6, oil outlet tube 7, seal ring 8, expansion chamber 9.
