Digital adjustment method of drilling pump concentricity

Abstract

The invention discloses a concentricity digital adjusting system for a drilling pump based on a ZigBee network. The concentricity digital adjusting system comprises a site control terminal, a data coordination terminal and a data processing computer. The site control terminal is connected with the data coordination terminal through the ZigBee wireless network, and the data coordination terminal is connected with the data processing computer through serial port communication. The invention further discloses a concentricity digital adjusting method for the drilling pump based on the ZigBee network, and the method depends on the concentricity digital adjusting system for the drilling pump based on the ZigBee network. According to the system, automatic networking is conducted through the ZigBee technology, complexity is low, the size is small, power consumption is low, carrying is convenient, input, processing and feedback of site concentricity assembly parameters can be practically completed in real time. According to the method, the adjusting period of concentricity is effectively shortened, and the adjusting precision of concentricity is improved.

Description

technical field [0001] The invention belongs to the technical field of oil and natural gas drilling control, and relates to a digital adjustment system for concentricity of a drilling pump based on a ZigBee network, and also relates to a digital adjustment method for concentricity of a drilling pump based on a ZigBee network. Background technique [0002] During the assembly process of the drilling pump, the concentricity between the crosshead and the center hole of the front wall plate of the frame is adjusted by changing the thickness of the lower guide plate gasket. The concentricity adjustment result of the drilling pump directly affects the contact force and motion trajectory between the crosshead and the guide plate. When the concentricity beat is too large, the drilling pump will not run smoothly, the guide plate, the crosshead will be worn, and the cylinder liner will be eccentrically worn, which will directly affect the product quality and service life.
