This system utilizes a standpipe pressure sensor as the pressure source and high-pressure rubber hoses for pressure transmission, enabling close-range observation of pressure values to prevent losses and accidents caused by distant misreadings. It can also be equipped with data acquisition and recording capabilities in conjunction with a drilling multi-parameter instrument according to user requirements. The system can quickly and accurately detect the operating condition of the mud pump, which aids in identifying faults with drilling tools or drill bit nozzles. It is suitable for use with oil drilling rigs, cementing trucks, fracturing trucks, and other related equipment.
