Double-body multi-cylinder high-pressure injection pump

Abstract

The invention relates to a dual-element multi-cylinder high-temperature mud injection pump, which comprises two multi-pulp cylinder pumps, an electromotor, a clutch, and a speed reducer. It is characterized in that: said two multi-pulp cylinder pumps have same structure, which are symmetrically arranged at two sides of electromotor; the output axle of electromotor is mounted with clutch, which via universal coupler is connected to the input axle of speed reducer; two sides of speed reducer individually have one output axle; two output axles via universal coupler are connected to the speed-variable slide key axles of relative multi-pulp cylinder pump. The invention has simple operation, easy maintenance, high drilling speed, and reduced cost. The invention uses 8 pulp cylinder pistons to work repeatedly, with lower motion speed (0.15-0.42m / s) and strong self-adsorption ability. The invention has 8 types of electromotor as (75-315kw).

Description

(1) Technical field [0001] The invention relates to an electromechanical liquid pump, which is suitable for conveying large-flow high-pressure mud in oil drilling and high-pressure water injection in oil production, clearing and smoothing the sediment at the bottom of ports, wharves and river channels, long-distance discharge of fly ash in large power plants, and mineral processing plants. Discharge of tailings sand, grouting and water blocking and reinforcement of large-scale underground projects, rescue and disaster relief of flooded wells and lanes, etc. (2) Background technology [0002] At present, the major domestic oil fields use 3NB130C mud pumps. Although the slurry discharge volume and pressure of the pump can meet the technical requirements of drilling, its deficiency has a great influence on oil drilling. The main inadaptability is: 1, the volume of the pump is too large, and its own weight is 24.35 tons, plus a huge transmission system and a large diesel engine...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing oil field drilling mud system, such as complex equipment, too large and heavy, expensive, inconvenient operation and maintenance, and provide a kind of power transmission and pump as one, multi-cylinder reciprocating action The powerful piston pump is 10 times lighter in weight and 5 times cheaper than the existing oilfield mud pump system, and has the functions of clutch, variable speed and self-priming; the amount of slurry discharge and pressure can be adjusted at will; it is convenient for operation, maintenance and repair Large multifunctional high pressure sister pump
