Abstract

The invention discloses a hydraulic cylinder structure for a drill pump, which comprises a plurality of suction hydraulic cylinders and a plurality of discharge hydraulic cylinders. Each suction hydraulic cylinder is communicated with the corresponding discharge hydraulic cylinder, the suction hydraulic cylinders and the discharge hydraulic cylinders are of an integral structure which is integrally formed, and the suction hydraulic cylinders and the discharge hydraulic cylinders form an integral hydraulic cylinder. The hydraulic cylinder structure for the drill pump reduces use of raw materials, lowers production cost, reduces processing faces, improves processing efficiency, and saves processing time.

Description

technical field [0001] The invention relates to the field of oil or natural gas drilling equipment, in particular to a hydraulic cylinder structure for a drilling pump. Background technique [0002] With the development of oil and natural gas exploitation, the drilling depth continues to deepen, and higher and higher requirements are placed on the drilling pump, the "heart" equipment of the drilling rig. The power of the drilling pump is required to be larger and the weight of the drilling pump is getting lighter and lighter The volume is getting smaller and smaller. This requirement is also an inevitable trend of the requirements of energy-saving products advocated all over the world. In order to meet this requirement, various manufacturers began to pay attention to the amount of steel consumed by the drilling pump per unit power, that is, the two indicators of "finished product consumables per unit power" and "rough consumables per unit power" to evaluate whether the dril...
