Abstract

The invention relates to the technical field of fracturing devices, and provides fracturing equipment and a control method thereof. The fracturing equipment comprises an oil supply device, a plurality of branch oil inlet pipes, a plurality of branch oil return pipes, a plurality of plunger mechanisms, a difference value detection device and a plurality of adjusting valve devices, wherein the oil supply device is suitable for communicating with the oil inlet end of each plunger mechanism through one branch oil inlet pipe, the oil outlet end of each plunger mechanism is suitable for communicating with the oil supply device through one branch oil return pipe, the difference value detection device is connected with the branch oil inlet pipes and the branch oil return pipes correspondingly, and each adjusting valve device is arranged on one branch oil inlet pipe. According to the fracturing equipment, the lubricating oil flow of each branch oil inlet pipe communicating with each plunger mechanism can be effectively balanced, so that the influence on the pressure of the lubricating oil of other branch oil inlet pipes due to faults of part of the branch oil inlet pipes is prevented, and the uniformity of the lubricating operation of each plunger mechanism is ensured.

Description

technical field [0001] The invention relates to the technical field of fracturing settings, in particular to a fracturing equipment and a control method thereof. Background technique [0002] At present, the existing fracturing equipment on the market, such as fracturing trucks, are special vehicles that press open the formation and squeeze the fracturing fluid into the cracks. They can also be used for hydraulic sand blasting, high-pressure hydraulic coal mining in coal mines, and high-pressure hydraulic rust removal on ships. , and the fracturing pump in the fracturing vehicle, such as the multi-plunger fracturing pump, mainly includes multiple plunger mechanisms. During normal operation, the multiple plunger mechanisms need to be lubricated to ensure their continuous normal operation. run. However, in the prior art, the oil supply device is usually connected with the main oil inlet pipe, and the main oil inlet pipe is divided into a plurality of branch oil inlet pipes to...
