The company's products have reliable quality and stable operation. Correct installation and use are very important. After the connection of gear pump,  motor, drive connector, pipeline connector, heating pipeline and circuit is completed, ensure that the connection is tight, the stress of components is  uniform, and the circuit meets the requirements of grounding, shielding and explosion-proof. After startup, set the speed at 30R / min and operate for  30 minutes. Observe whether the equipment has abnormal vibration and noise, whether there is material leakage, whether the pressure measurement  and temperature measurement instruments display normally, and whether the motor power output is stable without obvious fluctuation. If there is any abnormality, check the cause until the test is normal.

If there is no abnormality in the initial operation of the equipment, switch to  conventional production, adjust the motor speed until it is output according to the rated output, and it is not allowed to increase the output at a large  high speed, which is prone to pump shaft fracture, seal failure and other faults. After XX hours, stop the machine to replace the packing seal, remove  the accumulated material in the spiral groove of the sealing sleeve, and replace the bolts of the transmission parts. Pay close attention to the changes  of inlet and outlet pressure, temperature, current and voltage during use and deal with them in time.
