Technical Field
The utility model relates to a vane pump especially relates to an integral type vane pump.
Background
A vane pump, which is a pump that the vanes in the rotor groove contact with the pump shell (stator ring) and presses the sucked liquid from the oil inlet side to the oil outlet side; when the vane pump rotor rotates, the tip of the vane clings to the inner surface of the stator under the action of centrifugal force and pressure oil. The working volume formed by the two blades, the rotor and the inner surface of the stator firstly absorbs oil from small to large and then discharges oil from large to small, and when the blades rotate for one circle, oil absorption and oil discharge are completed once.
The traditional vane pump body is formed by assembling a pump shell and a pump ring, and the two parts have high matching precision and are difficult to process inner and outer matching surfaces in the production process; and the pump shell and the pump ring are in a separated mode, and in a certain working period, the pump shell and the pump ring can be gradually rusted, so that the pump ring is inconvenient to replace.
Therefore, there is a need to provide a new technical solution to overcome the above-mentioned drawbacks.

Preferably, the inner surface of the pump casing consists of two arc surfaces with different radiuses.
Preferably, the rotor is disposed coaxially with the working surface of the pump housing.
Preferably, the rotor is composed of two connecting shafts, and the blades are mounted on the connecting shafts.
Preferably, the connecting shaft is provided with a positioning clamping groove, the blades are arranged in the positioning clamping groove, and a movable gap is formed between the blades.
Compared with the prior art, the utility model discloses following beneficial effect has:
the pump body of the utility model has no pump ring in the traditional sense, thereby effectively solving the problem that the pump shell and the pump ring of the traditional pump body are separately arranged, and the pump shell and the pump ring are rusted to be dead in a certain working period to cause the pump body to be incapable of working, so that the pump body can continuously and efficiently work; meanwhile, the processing difficulty of the pump body is reduced, and the processing cost is reduced; in addition, the pump body is after using a period, only need to change the blade can, need not to change the pump body, and then improved maintenance efficiency, reduced the replacement cost.
