What Are The Common Problems In The Operation Of Photoelectric Guiding Devices?

Preparations and precautions before starting the photoelectric guiding device include a. Comprehensive inspection of 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 a, the operating pressure of the pump should be stable, and the pressure fluctuation is not more than 1 kg/cm 2 . b. During the operation of the pump, evacuation should be avoided to avoid dry friction and seal damage on the sealing surface. c. If there is a slight leakage after the pump starts, 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.

d. 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 photoelectric we guide: a. Keep the sealed chamber 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.

b. The photoelectric web guide device manufacturer believes that for the mechanical seal using the pump external sealing oil system, the oil sealing system should be started first. Stop the oil sealing system after stopping. c. After the hot oil pump is stopped, the cooling water of the sealing oil chamber and the end face seal cannot be stopped immediately. When the oil temperature of the end seal is lowered to below 80 degrees, the cooling water can be stopped to avoid damage to the sealing parts.
