The process of acquiring the pressure of the inlet and the outlet of the pump in the current pump hydraulic characteristic test is as follows: the working process of the engineering machine is that two persons are needed to take records of the other engineering machine, and the working process is carried out by detaching a field YP plug or a local pressure gauge bellows, connecting a temporary high-precision pressure gauge through a pressure guiding hose, reading the pressure gauge by the aid of a semi-squatting posture of one engineering machine and a sight line of the high-precision pressure gauge lifted by hands, and recording the pressure gauge by the other engineering machine.
Aiming at the process that the sight line of a high-precision pressure gauge lifted by hands is flush with the semi-squatting posture of an engineer to read, the following problems exist:
firstly, data acquisition lasts for 5 minutes, and operators are tired when keeping the posture for 5 minutes;
secondly, a special person is needed to lift the pressure gauge by hand, so that the investment of operating personnel is increased, and the working efficiency is lower;
lifting the pressure gauge by hand can shake to cause data fluctuation, and the sight line is difficult to keep level with the pressure gauge, so that the error of the pressure reading of an inlet and an outlet is large; similar problems exist in the installation work of many temporary pressure gauges in nuclear power plants.
