What Are The Preparations For The Photoelectric Guiding Device Before Starting?

Preparation and precautions before starting the photoelectric guiding device a. Thoroughly check the mechanical seal, and whether the auxiliary device and pipeline installation are complete, and meet the technical requirements. b. Perform static pressure test before starting the mechanical seal to check whether the mechanical seal has leakage. If there are more leaks, you should find out the reasons and try to eliminate them. If it is still invalid, it should be disassembled and reinstalled. Generally, the static pressure test pressure is 2~3 kg/cm2.

c. Press the pump to turn the disc to check if it is light and even. If the car is struggling or not moving, check whether the assembly size is wrong and the installation is reasonable. The problem of photoelectric guide operation: the operating pressure of the pump should be stable, and the pressure fluctuation should be no more than 1 kg/cm 2 .

When the pump is in operation, evacuation should be avoided to avoid dry friction and seal damage on the sealing surface. If there is a slight leak after the pump is started, it should be observed for a while. If the leakage is still not reduced after 4 hours of continuous operation, the pump should be stopped.

Sealing should be checked frequently. During operation, when the leakage exceeds the standard, the heavy oil is not more than 5 drops/min, and the light oil is not more than 10 drops/min. If there is no improvement trend within 2-3 days, the pump plug should be stopped to check the sealing device.

Installation and shutdown of the photoelectric guide device: The sealed chamber should be filled with liquid before starting. For transporting the solidified medium, steam is applied to heat the sealed chamber to melt the medium. The car must be driven before starting to prevent the soft ring from breaking due to sudden start.
