The working principle and characteristics of vane pump

vane pump, the working principle of the vane pump vane pump characteristic

a, the working principle of vane pump

common sliding vane pump is usually used to transport medium pressure oil material, high viscosity liquid, the increase of sliding vane leakage, therefore limited to general viscous liquid. Common vane pump working principle of the same heavy sliding vane pump can be used to transport corrosive, high viscosity fluid half parts even solid blue. In this situation can only use single vane pump and sliding in the rotor slot. Conveying liquid, abradability, need to use wear-resisting material within the pump protection.

the structure of the vane pump as shown in figure 19 & ndash; 24, with radial slots of the stator in with eccentric rotor water pump, vane in the rotor's radial slot. Sliding vane can be two or more pieces, the rotor rotates under the action of centrifugal force, the sliding vane rotor body thrown, sliding along the stator inner surface. Vane pump working principle of the stator and sliding vane constitute a sealed cavity increases gradually with the increase of eccentric cavity, continue to rotating cavity decreases to zero, and is in turn, began to liquid in the cavity between the vane self-priming people breathe in, and then pressure to discharge area, complete liquid conveying process.

2, the characteristics of vane pump is as follows: 1) - Rapid self-priming ability: can be up to 5 m height difference, can be used in underground storage tanks, self-priming time less than 20 s, 2) Reliable sealing structure: the use of special structure of the mechanical seal. Wear-resisting, reliable. 3) Since the irrigation, and dry running ability: without irrigation pumps, and can make the pump dry running 10 min. 4) But not degrade the performance of the pump, greatly increases the service life of the pump 5) Simple structure, easy to maintenance, inspection, cleaning, replacing vane, only a few minutes.
