Self-cleaning filter literally believe that many people can guess that it is a kind of automatic cleaning, high degree of automation of filtration equipment, at the same time it also has automatic blowdown and other functions, has been widely used in many fields, but in the use of the process will also appear fault, thus affecting the normal use of the filter. So, how to deal with the failure of the self-cleaning filter?
Fault 1: Water leakage occurs in the self-cleaning filter
The water leakage problem of the self-cleaning filter will generally appear in the transmission shaft part of the filter (the water leakage of the cylinder and the welding part of the flange is not in this scope). There are basically two reasons for this problem.
1. The material or specification of the transmission shaft sealing ring does not meet the requirements, so replace the sealing ring that meets the requirements.
2. the sealing ring after a long time of operation wear, cause the transmission shaft and filter body between the seal is not strict and water leakage, like this case to replace the corresponding specifications of the sealing ring can solve the problem.
Fault 2: The automatic blowdown valve of the self-cleaning filter is faulty
The fault of automatic blowdown valve is manifested in that the blowdown valve does not move or the blowdown valve cannot be opened and closed during automatic cleaning.
1. this problem is generally the selection of domestic electromagnetic blowdown valve, the solenoid valve for pilot type, first by the solenoid to open the pilot hole, and then rely on the pressure of the water in the system to open the diaphragm to open the valve.
2. because there are many impurities in the sewage water, it is easy to block the pilot hole, resulting in the solenoid valve does not act or closed loosely after opening.
3. the selection of electric ball valve or hydraulic solenoid valve as blowdown valve, it completely solves the ordinary solenoid valve as a self-cleaning filter automatic blowdown valve easy to fail.
Fault 3: The automatic cleaning control system fails
Frequent fault startup of self-cleaning control system leads to increased cleaning water and shortened filter life.
1. This problem is generally caused by the parameter setting of the filter not in line with the working condition.
2. This is mainly the problem of cleaning differential pressure and cleaning time interval set by the differential pressure controller. The problem of control system can be solved by setting a larger differential pressure and time interval when the filter cleaning system starts frequently.
Self-cleaning filter does not need to be maintained without problems. In fact, self-cleaning filter needs regular maintenance and overhaul. The purpose of doing so is to ensure that the failure of equipment can be detected and handled in a timely manner, so that the self-cleaning filter can run stably for a long time.
The above is a simple description of how to deal with the failure of the self-cleaning filter.
