Summary of the invention
At the deficiency that prior art exists, the utility model provides a kind of stable, vane pump of increasing the service life, reducing production costs.
For achieving the above object, the utility model provides following technological scheme: a kind of vane pump, include the pump housing, be located at transmission shaft on the pump housing, be sheathed on port plate, the side plate on the rotatingshaft and be located at port plate and side plate between rotor, be evenly equipped with some rotor on the side face of rotor, be provided with in the rotor with it and be the blade that slippage cooperates, the described pump housing is provided with inlet port and presses hydraulic fluid port, it is characterized in that: symmetrical respectively being provided with makes the pressure balance part of the interior blade of rotor upper rotor part groove along the rotor axial location between described side plate and port plate and the rotor.
Adopt technique scheme, by between side plate, port plate and rotor respectively symmetry the pressure balance part is set, make that the both sides of rotor axial (promptly along) has been subjected to the location of pressure balance part towards the both sides of side plate and port plate for blade in the rotor upper rotor part groove, prevent rotor in operation process, blade in its rotor, move axially and contact with side plate or port plate cause blade, side plate or port plate scratch or the pump housing is ground extremely; Thereby reached purpose stable, that increase the service life, traditional relatively vane pump, it is in operation and occurs scratching or grinding after death needing frequent keeping in repair, the utility model has then been avoided contacting between blade and side plate and the port plate, produces and the cost of maintenance thereby reduced.
The utility model further is set to: the pressure balance part between port plate and side plate and the rotor includes respectively is located at side plate towards the balancing slit on the rotor one end end face and be located at the balancing slit of port plate on rotor one end end face, balancing slit includes all presses a store oil part and an end partly to be connected with all pressing store oil, the other end and the outside oil-feed part that is connected.
Adopt technique scheme, the pressure balance part is set to be located at the balancing slit on side plate and the port plate, and balancing slit includes and all presses store oil part and oil-feed part, after being provided with like this, adopt oil pressure that the epitrochanterian axial both sides of being positioned at of blade are positioned, make between side plate and port plate and the rotor produce little from, help the formation of oil film, the axially locating of blade is guaranteed.
The utility model further is set to: the store oil of all pressing on port plate and the side plate partly is respectively around all indentations chamber of port plate and the setting of side plate half cycle, and oil-feed partly is an end and all presses chamber conducting, the damping hole of the other end and outside conducting.
Wherein, all press the chamber and form, connect conducting by damping hole between two sections arcuation short slots by two sections arcuation short slots.
Adopt technique scheme, it is even along the both sides pressurized of rotor axial that blade is set like this, and all press the chamber and is made up of two sections arcuation short slots, by damping hole connection conducting, easy to process like this between two sections arcuation short slots, can reduce manufacturing procedure.
Below in conjunction with accompanying drawing the utility model is further described.
