Vane pump working principle and product performance characteristics
Vane pump works: vane installed in the slotted rotor, the rotor eccentric installed in the pump body, the rotor rotates, the vane slides out of the rotor, close to the surface of the pump slide, the rotor , Vanes, the pump chamber formed by the rotation of the rotor chamber, the size of its space was cyclical changes, the cavity increases, the inhalation of the medium, the smaller the cavity, the discharge medium, cycle again and again to complete the media transport process. Vane pump working principle Vane pump performance characteristics: (1), the structure is compact, the flow is more uniform, small size, pulsation and noise, smooth operation. (2), strong self-priming capacity, for the suction underground tank, the lifting height of up to 7.5m. (3), high efficiency, centrifugal force by the pump vane, mechanical thrust, hydraulic pressure of the combined effect, close to the stator curve movement, so that the pump has a unique high efficiency. (4), to maintain the performance of self-adjusting vane, vane slide out from the rotor slot, continue to add wear, without reducing pump performance. This gear pump is essentially different. (5) The ability to deliver shear-sensitive liquids. The high-efficiency design of the hydrodynamic vane reduces the shear and agitation of the vane against fluid by the pump while driving and avoids any changes in the fluid properties resulting therefrom. (6), reliable sealing, for viscosity, high temperature medium characteristics, the use of special mechanical seal structure, with a safe, durable and reliable features. (7), safe and sensitive pressure assurance, set the safety relief valve in the pump, the sudden closure of the export system, the outlet pressure rise does not exceed 0.15Mpa, on the one hand to ensure the safety of pumps and systems, on the other hand, to ensure that the motor However, contained. (8), maintenance is simple and convenient, open the pump cover, put forward the old slide, insert a new slide. In just a few minutes, your pump can get back into work. Daily inspection is equally easy.
