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...
