Screw-type chillers will inevitably encounter some large and small problems during operation. For water-cooled screw chillers, it is very dangerous if water breaks occur, and it must be handled in a timely and effective manner. If the delay is better, it will cause serious troubles in the screw chiller and even cause the unit to fail to operate normally. Therefore, in the event of a water failure, it needs to be disposed of immediately.
In the case of normal operation, the screw chiller relies on the cooling tower to remove the hot gas from the water source. If there is no flow of any water source at high speed, then a large amount of heat cannot be volatilized in time. The rate of temperature rise is very fast. When the temperature reaches the critical point of high temperature, the screw-type cold water machine protects itself by stopping the machine. Therefore, as long as the water failure occurs, the screw chiller usually stops running for about 15 minutes to protect the core components of the screw chiller.
If the screw chiller has a water breakage fault, the specific cause of the water cut will be analyzed by the front step. If there is a problem with the water source, the operation of the screw chiller can be resumed as long as the supply of the water source is restored in time. If it is a fault of the pump type (such as the wrong connection of the wire, or the loose joint, etc.), it is necessary to carry out a comprehensive inspection of the equipment at this time, promptly eliminate the failure of the pump, and conduct a comprehensive test at the same time. Ensure that the pump returns to normal operation before the screw chiller can be turned on normally.
Here to remind everyone, when repairing the screw chiller, be sure to remember to perform maintenance after the shutdown. Because the running screw-type cold water machine generates more heat, it will also stop after about ten minutes of operation. Therefore, the maintenance inspection in the state of shutdown can avoid the generation of extra high temperature, and can mainly ensure that the screw chiller is in the normal operating temperature range, so that the screw chiller can be in normal operation state.
It is not necessary to panic when encountering various screw chiller failures. Careful analysis of the screw chiller with specialized equipment can identify the root cause of the failure. Then, according to your specific ability, develop a suitable maintenance plan, and ensure that the screw chiller is re-run in a short period of time.
