Description
Technical field
The utility model relates to a kind of air pump, especially a kind of fuel cell separators air pump.
Background technique
Be used for providing gas raw material to fuel cell, as hydrogen, methane etc., requiring supply gas not contain lubricated wet goods impurity is unlubricated structure in the air-breathing and injection section of gas promptly, the gas supplied flow can be a small flow, but requires the stability of air pressure better; It as the patent No. a kind of air pump of 200580011023.1, for the lubricant oil that makes ball bearing does not take in the gas supplied as far as possible, the live axle of the running shaft of pump mechanism and motor is designed to one, running shaft is supported by the plural at least ball bearing that is provided on the pump mechanism, in the space of ball bearing sealing, enclose oiling agent, make lubricant oil try not to spill to the outside, still leaf structure because of this structure employing, for axle rotation and ball bearing inner ring are rotated, oiling agent can not positive confinement, after improving, the temperature rise of bearing still have less amount of lubrication oil to spill, and this structure assembling more complicated.
The model utility content
The technical problems to be solved in the utility model provides a kind of unlubricated oil leakage, better, the simple fuel cell separators air pump of assembling of tightness.
For achieving the above object, the solution that the utility model adopted is: a kind of fuel cell separators air pump, comprise pump case, motor, valve seat, top cover, motor is contained on the end face of pump case, valve seat, top cover is contained on the other end of pump case successively, the reciprocating link assembly that is connected with motor is housed in the pump case, the diaphragm unit that is connected with link assembly, air inlet is housed and the non-return valve block of giving vent to anger on the valve seat, the breather check valve sheet is stuck in the groove of an end face of valve seat by spring ring, the non-return valve block of giving vent to anger is stuck in by another spring ring in the groove of another end face of valve seat, and valve seat is provided with gas-entered passageway and outlet passageway.
Above-mentioned fuel cell separators air pump, described link assembly is made up of eccentric wheel, bearing, connecting rod, and the inner ring of bearing is enclosed within on the eccentric wheel, and the outer ring is enclosed within on the connecting rod, and eccentric wheel is located on the motor driving shaft, and an end of connecting rod is connected with described diaphragm unit.
Above-mentioned fuel cell separators air pump, described diaphragm unit is made up of flexible sheet, screw and two pads, and described flexible sheet is located between two pads, and screw passes described flexible sheet and two pads and is fixedly arranged on the link assembly.
Above-mentioned fuel cell separators air pump, the described air inlet and the non-return valve block of giving vent to anger adopt the structure of dumbbell-like shape, and a sealing gasket also is set between valve seat and the top cover.
Above-mentioned fuel cell separators air pump, described pump case side and bottom surface are provided with L shaped end cap.
Above-mentioned fuel cell separators air pump, an end face of described L type end cap is equipped with an axle sleeve.
By adopting aforementioned structure, the beneficial effects of the utility model are: because the volume that adopts the vibration of diaphragm to change seal air cavity carries out air-breathing and barrier film air pump exhaust, make drive part and gas compression member separate fully, therefore the lubricant oil of drive part use can't enter air path part, guarantees the purity of air feed.The air inlet and the non-return valve block of giving vent to anger are pressed on the valve seat by spring ring in addition, and the tightness of gas circuit improves, and the dumbbell-like shape air inlet is given vent to anger the non-return valve block because two ends are stressed, be not easy distortion, set up sealing gasket between top cover and the valve seat, the tightness of whole gas circuit is better, and the air pump pressure stability also greatly improves.Because valve seat has air inlet and outlet passageway concurrently, link assembly and cap structure are simple, and the side of pump case and bottom surface need only a L shaped end cap and can seal, so overall structure is simply easy to assembly.
