Anti-crack liquid end assembly

Abstract

The invention discloses an anti-cracking fluid end assembly, which includes a base plate, the top of the base plate is fixedly connected with a main body of the fluid end assembly, both sides of the base plate are fixedly connected with first baffle plates, two first baffle plates The opposite sides of the plates are fixedly connected with first hydraulic telescopic rods. The present invention is provided with a base plate, a first baffle plate, a horizontal plate, a fixed plate, a hot air blower, a vertical plate, a belt, a pulley, a casing, a motor, a top plate, a frame, a through-hole plate, a second baffle plate, and a first hydraulic expansion rod. , the main body of the fluid end assembly, the mounting plate, the controller, the first threaded cylinder, the vertical rod, the limit plate, the second hydraulic telescopic rod, the through-hole pressure plate and the second threaded cylinder are used together to solve the problem of the existing hydraulic The force end assembly usually cannot be clamped and limited during use, and usually does not have the function of continuous heating by a hot air blower, so that it may crack in harsh environments, resulting in a certain impact on its service life question.

Description

technical field [0001] The invention relates to the technical field of liquid end assemblies, in particular to an anti-crack liquid end assembly. Background technique [0002] The fluid end assembly is an essential and important vulnerable part on the fracturing vehicle. Since the fluid end assembly has been working in the harsh environment of high-pressure fluid medium for a long time; especially in recent years, oil, natural gas, shale gas, etc. A large number of mining, the difficulty of mining continues to increase, and the performance requirements for fracturing equipment used in oil extraction are getting higher and higher. Innovative research and development of high power, large displacement, corrosion resistance, wear resistance, high pressure, and service life of the valve box It is an inevitable trend to have a new type of liquid end assembly that is long, wearable parts have a long life, and is easy to disassemble. [0003] In the process of oil and gas exploitat...
