Abstract

The invention discloses an energy-saving type external-meshing gear pump, and relates to a pump. The energy-saving type external-meshing gear pump comprises an oil inlet (1), an oil outlet (2), a pump body (3), a driving gear (4) and a driven gear (5), wherein the driving gear (4) and the driven gear (5) are arranged in the pump body (3) and are meshed with each other, two ends of the center of the pump body (3) are respectively provided with the oil inlet (1) and the oil outlet (2), the pump body (3) is arranged in a sealing manner through sealing faces at the two ends of the pump body (3), and the oil inlet (1) and the oil outlet (2) are each provided with a flow counter. The energy-saving type external-meshing gear pump has the advantages of simple structure, light weight, low manufacturing cost, reliability in work, and higher volumetric efficiency and mechanical efficiency.

Description

technical field [0001] The invention relates to a pump, in particular to an energy-saving external meshing gear pump. Background technique [0002] The energy-saving external gear pump has simple and compact structure, small size, light weight, good self-priming, no sense of pollution, reliable operation, low cost and wide application. The disadvantage is that the flow uniformity is poor and the noise is large, which does not conform to the modern design concept. The application in occasions with higher requirements on flow uniformity is limited. [0003] The main defects of traditional energy-saving external gear pumps are: low volumetric efficiency and mechanical efficiency, and high noise. Under low pressure, light load and low power conditions, the allowable speed is low and the volumetric efficiency is also low. Bring very big inconvenience to its use. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the purpose of the present invent...
