Noise reduction rotor mechanism for pump

Abstract

A noise reduction rotor mechanism for a pump relates to the technical field of oil delivery and comprises a base, a motor is fixed on the base, a connecting sleeve is fixed on the left side of the motor, a pump body is fixed on the left side of the connecting sleeve, an end cover is fixed on the left side of the pump body, a liquid outlet is formed in the front side of the pump body, and a liquid inlet is formed in the rear side of the pump body. The upper and lower parts of the bearing seats are rotatably connected with transmission shafts through bearings, the transmission shafts are coaxially connected with rotors located in the two bearing seats, the right side of the upper transmission shaft is coaxially and fixedly connected with a driving wheel, the right side of the lower transmission shaft is coaxially and fixedly connected with a driven wheel meshed with the driving wheel, and the two rotors synchronously and reversely rotate; according to the noise reduction rotor mechanism for the pump, the multiple grooves for filtering the bubbles are formed in the outer circle of the rotor in the axial direction, the bubbles can be filtered through the grooves, and therefore the problem that the rotor pump idles during oil-gas mixed transportation is solved.

Description

technical field [0001] The invention belongs to the technical field of petroleum transportation, and more specifically relates to a noise reduction rotor mechanism for a pump. Background technique [0002] Oil and gas mixed transportation pumps are needed in the process of oil transportation. Oil and gas mixed transportation pumps are used in the process of gathering and transportation. They mainly transport crude oil containing gas, water, sand, etc. to realize centralized purification, separation and storage of crude oil. It can reduce the wellhead pressure and increase the output of a single well or area. Among them, the structure of the oil and gas mixed transport pump specifically includes a rotor pump. The rotor pump refers to changing the working volume through the relative movement between the rotor and the pump body, thereby increasing the energy of the liquid. Pump, the existing rotor pump has high noise and unstable operation. It is easy to idle when the gas conte...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims to solve the problem that the existing rotor pump is easy to idle when the crude oil has a large gas content, the oil output is interrupted, and the noise caused by the extrusion of crude oil by the two rotors in the rotor pump affects the use environment, and the pump body does not have the ability to reduce pressure. question
