Electric drive fracturing pry lubricating system, fracturing pry and lubricating control method

Abstract

The invention provides an electric drive fracturing pry lubricating system, a fracturing pry and a lubricating control method, and relates to the technical field of shale gas exploitation equipment. The electric drive fracturing pry lubricating system is used for injecting lubricating oil into a to-be-lubricated device. The electric drive fracturing pry lubricating system comprises a lubricating pump, a power end oil tank, a temperature control flow divider valve and a heat dissipation module. A pump inlet end of the lubricating pump communicates with a power end oil tank, and a pump outlet end of the lubricating pump communicates with a valve inlet of the temperature control flow divider valve. The temperature control flow divider valve comprises a first valve outlet and a second valve outlet, wherein the first valve outlet and the second valve outlet both communicate with a device to be lubricated. The heat dissipation module is arranged on a communicating pipeline of the second valve outlet and the device to be lubricated. According to the electric drive fracturing pry lubricating system, the fracturing pry and the lubricating control method, the temperature control flow divider valve controls the lubricating oil to directly enter the device to be lubricated for lubrication or to firstly dissipate heat according to the temperature of the lubricating oil, so that waste of heat dissipating capacity is prevented; and the lubricating oil enters the device to be lubricated to lubricate at a better temperature and state, so that the lubricating effect is improved.

Description

technical field [0001] The invention relates to the technical field of shale gas exploitation equipment, in particular to an electric-driven fracturing skid lubrication system and a lubrication control method. Background technique [0002] In the field of petroleum, fracturing refers to a method that uses hydraulic action to form cracks in oil and gas layers during the process of oil or gas recovery, also known as hydraulic fracturing. Fracturing is to artificially create fractures in the formation, improve the flow environment of oil underground, increase the production of oil wells, and play an important role in improving the flow conditions at the bottom of oil wells, slowing down interlayers and improving the production status of oil layers. [0003] As a commonly used fracturing device, the fracturing skid includes multiple power components such as motors and fracturing pumps. During operation, lubrication is required due to relative motion such as rotation. Most of th...

Problems solved by technology

[0004] The problem solved by the present invention is that the existing cooling device and the overall lubrication process are relatively simple, and do not effectively dissipate heat for different situations of lubricating oil, which easily causes waste of heat dissipation and overload of the lubricating oil motor, which affects the motor and fracturing Insufficient lubrication of several components such as the pump
