Problems solved by technology

[0003] Rotor lobe pumps are widely used in the field of modern pipeline transportation. However, the existing rotor lobe pumps often have the following shortcomings during use. It is often difficult to ensure that the rotor and the pump There is effective sealing between the bodies for a long time, and often there is a slight air leakage in the rotor pump, which will greatly reduce the overall energy efficiency of the device and require maintenance and replacement

Abstract

The invention discloses a cam rotor pump. The cam rotor pump comprises a fixed base, a driving mechanism and a pump shell, wherein the driving mechanism and the pump shell are fixedly installed on thefixed base. The cam rotor pump further comprises two transmission shafts fixedly connected with the output end of the driving mechanism; at least one partition disc is fixedly arranged in an inner cavity of the pump shell; at least one rotor mechanism is rotationally connected to the inner cavity of the pump shell; an outer cover is detachably installed at an opening of the pump shell; and the two transmission shafts penetrate the pump shell, and the extending end of the outer cover is sleeved with an adjusting screw. In the cam rotor pump, a plurality of rotor mechanisms are adopted for isolating independent running mechanisms, the plurality of rotor mechanisms work independently, and the defect that the whole device fails due to failure of the single rotor mechanism is avoided; and theadjustable inserting rotor mechanisms are adopted, and under the condition that the output rotating speeds of the two transmission shafts are controlled to be unchanged, the overall output efficiencyof the rotor pump is effectively adjusted and used.

Description

technical field [0001] The invention belongs to the technical field of rotor pumps, in particular to a cam rotor pump. Background technique [0002] The rotor lobe pump is one of the most advanced fluid equipment in the world. Its rotor is fully rubber-coated and has strong wear resistance. The high-precision clearance fit between the rotor and the housing has strong self-priming force and high lift force. Conveying various viscous or particulate-containing media, it is suitable for various complex fluid media. The working principle of the lobe rotor pump mainly relies on two synchronous counter-rotating rotors to generate suction at the inlet during the rotation process, so as to suck in the fluid to be transported. of materials. [0003] Rotor lobe pumps are widely used in the field of modern pipeline transportation. However, the existing rotor lobe pumps often have the following shortcomings during use. It is often difficult to ensure that the rotor and the pump There i...
