Abstract

The invention discloses a multifunctional vane pump with high efficiency and long service life, which comprises a pump shell, an impeller, an impeller chamber, a fluid spin chamber, a water inlet, a water outlet and a motor, wherein, the impeller consists of at least one group of arc-shaped channel vanes closed at one side and amplified axially; the pump shell is internally provided with a round dual chamber or multi-chamber provided with the water inlet and the water outlet. The efficiency of the vane pump is over 80 percent, the energy is saved by more than 10 percent while the noise is lower than 80dB; the impeller is not easy to wear basically and the service life can be prolonged by more than 2 times; also the vane pump has various functions and can be used for pumping fluid, solid matters, and mixed fluid and solid matters, etc. The comprehensive economic, technical and performance indexes of the vane pump achieve the leading level both at home and abroad and also a new energy transmission theory is established.

Description

technical field [0001] The invention is a high-efficiency and long-life multifunctional vane pump, which belongs to the field of energy-saving equipment manufacturing and automation. Background technique [0002] The pump is a general-purpose machine that is widely used, and it is also one of the machines that consume a lot of energy. From a discipline point of view, the pump is the application and development of fluid mechanics. In a thermal power plant, the pump is an important part of the power cycle and one of the important auxiliary machines. The safe and economical operation of the pump plays an important role in the safe and economical power generation of the power plant. From an energy point of view, a pump is a type of fluid machinery that can convert the mechanical energy of the prime mover into the pressure potential energy and kinetic energy of the fluid being conveyed. Pumps are widely used in various sectors of the national economy, such as drainage and irri...
