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.
