Common failure and life loss of automatic double-opening cargo shower
Common failure and life loss of automatic double-opening cargo showerIn the use of an automatic double-opening shower, some common faults will have different degrees of impact on its life.Fan failure is one of the more common problems. As a key component to provide shower power, once there is a failure, such as a fan does not work, reverse or the wind speed being too small, it will directly affect the blowing effect of the cargo shower room. The fan may not work due to motor damage, line failure, overheating protection device triggered, and other reasons. When the fan is not working, it can not produce high-speed air to blow the goods, and the pollution risk of the clean room is increased, it may also cause other components such as filters to accelerate damage due to a long time not being effectively cleaned, thereby shortening the overall life of the cargo shower. Fan inversion or wind speed is too small, will make the blowing force insufficient, can not completely remove the pollutants on the surface of the goods, reduce the purification capacity of the cargo shower, long-term in this state, will also accelerate the wear of related components, affecting the life of the equipment. Door failure is also an important factor affecting the life of the cargo shower. The door of the automatic double-open cargo shower room is frequently opened and closed, which is prone to problems such as the door cannot be opened, the closing is not strict, and the automatic induction failure. The door cannot be opened or closed loosely, which will destroy the air tightness of the clean room, resulting in unpurified air entering the clean area, and increasing the risk of pollution. The automatic induction failure of the door may make the operator misoperate, such as opening the door by force, which will not only damage the mechanical structure of the door, but also may lead to the failure of the electronic interlock system, affecting the normal use of the door and the overall performance of the cargo shower room, and shorten the service life of the equipment. Control system failures cannot be ignored either. The control system is responsible for coordinating the operation of various components of the cargo shower room. Once there is a failure, such as the failure of the control panel key, the program error, etc., it will cause the cargo shower room to not work normally. The failure of the control panel keys may be caused by aging keys, poor contact, and other reasons, which will cause inconvenience to the operator and affect the operation efficiency. Program errors may lead to abnormal shower time Settings, door switching logic confusion, and other problems, so that the operation of the shower room out of control, unable to meet the requirements of clean room use, in the long run, will cause additional losses to the various components of the equipment, reduce the service life of the equipment. When these common faults occur, they should be repaired in time. For fan failure, if the fan does not work, first check whether the emergency switch of the outer box is off, if it is off, it can be restored according to the operation requirements; If it is not this problem, it is necessary to further investigate the motor, line and other aspects of the fault, you can ask a professional electrician for maintenance, such as checking whether the motor winding is short circuit, open circuit, whether the line is damaged, virtual connection, etc., according to the specific problem to repair or replace the damaged parts. If the fan is reversed or the wind speed is too small, check whether the 380V three-phase four-wire line is reversed. If it is reversed, the connection should be corrected in time; At the same time, check whether the filter is blocked or has too much dust. If there is a problem, replace the filter in time. If the door cannot be opened during door fault maintenance, check whether the door lock is damaged and whether the door transmission device is normal. If the door lock is damaged, a new door lock needs to be replaced; If the transmission of the door is faulty, it can be repaired or the relevant parts can be replaced. If the door is not strictly closed, check whether the door seal is aging or deformation, and if there is a problem, replace the door seal; At the same time, check whether the installation of the door is loose. If it is loose, re-fix the door body. Automatic sensing failure, check whether the light sensing system is installed correctly and whether there is dust blocking, if there is a problem, adjust the position of the light sensing system, or clean the sensor. When the control system is in fault maintenance, the key on the control panel fails and can be replaced with a new key; For Program errors, contact the shower manufacturers, by professional and technical personnel to debug and repair the control system, and reset the correct program parameters. |
