Abstract

The invention discloses a device for surface treatment of a fracturing pump valve box. The device comprises a hanger rail and a base, the hanger rail is mounted above the base, and a nitriding furnace, a phosphating pool, a passivation cylinder and a drying oven are sequentially mounted on the base from left to right. The nitriding furnace is provided with a vacuum layer, so that the device has abetter heat preservation effect; a gas check valve added is more suitable for the treatment method of the device and simplifies the operation; and the passivation time is short in the passivation cylinder, and the surface of a workpiece is sprayed, so that the passivation is more thorough and specific, and the tension of a groove of the workpiece on liquid is eliminated.

Description

technical field [0001] The invention relates to the technical field of oil exploitation equipment processing, in particular to a device for surface treatment of a valve box of a fracturing pump Background technique [0002] In essence, fracturing is to use the fracturing pump to generate high-pressure liquid, so as to transmit the pressure. After cracks are generated in the oil well and the proppant cannot be filled, an area with extremely high permeability is formed. The application of fracturing With decades of history, Ning has effectively increased the amount of oil extracted. During construction, the high-pressure pump injects liquid into the formation at a very high speed. Because the absorption rate inside the formation is much lower than the injection speed, the formation ruptures , and the cracks will gradually increase, the more liquid is injected, the greater the pressure of the pump, the larger the cracks will be, until the absorption rate inside the formation is...
