Description
Technical field
The utility model relates to Hydraulic Field, in particular to a kind of sliding vane pump.
Background technique
A kind of positive displacement pump commonly used of sliding vane pump is widely used in the industrial field that collects defeated and lifting, and it has very strong suction capacity; Be specially adapted to the oil dock emptying, Cargo Oil on the ship, sweeping; Train unloads occasions such as groove, and fuel tank, and refuelling truck and oil depot, gas station's oil plant are carried.Sliding vane pump can be used for carrying the lightweight oil plant, and sticking oily effect is better.Common single action vane pump working principle is as shown in Figure 1.General single action vane pump mainly consists of the following components: live axle 1, connecting key 2, rotor 3, slide plate 4 claim that also blade, stator also claim pump case 5.Live axle is arranged in the said pump case, and rotor is enclosed within on the said live axle and with said live axle and is fixedly connected, slide plate, from said rotor extend laterally and between said rotor and said pump case.When motor or other prime mover rotating driveshaft 1; Live axle 1 drives rotor 3 rotations through key 2; Rotor 3 drives slide plate 4 and in the eccentric chamber of pump case 5, rotates; Blade 4 under action of centrifugal force with bore of stator contact seal because blade 4 and stator 5 constitute the volume-variation of chambers, make sliding vane pump produce suction and squeezing action by convection cell.
Corresponding with common single action vane pump; The profile line of stator or pump case 5 inner chambers is revised as the elliptical shape or the sub-elliptical shape of symmetry; Profile line can be multiple curvilinear equation, simultaneously at stator or pump case 5 each 2 of suction port and exhaust ports is set, and the circumferential interval angle of suction port and exhaust port is 90 ° usually; The double action vane pump that Here it is uses always is at present seen shown in Figure 2.Live axle revolves and turns around, and double action vane pump sucks discharges each twice.Compare with single action vane pump, because structure and stress load symmetry, double action vane pump often can obtain bigger discharge capacity, reduces the noise of sliding vane pump simultaneously, improves the reliability of parts such as live axle.
