The air-cooled chiller can provide users with process chilled water from 3 to 35°C, or low-temperature freezing fluid at 0 to minus 45°C, ensuring that the user's equipment or product achieves the purpose of cooling. In view of the fact that some users' air-cooled chillers do not need to operate for 24 hours and may stop after work, Dongyuejin specially shares the following precautions when shutting down the air-cooled chiller.
1. If it is necessary to stop the air-cooled chiller (non-long-term shutdown) normally, the 220V power supply cannot be cut off, and the oil heater in the crankcase must be kept in an electrically heated state during the shutdown of the air-cooled chiller.
2. After the circuit breaker trips, it cannot be switched on easily. It is also not possible to start the motor directly across the circuit breaker. The motor and wiring of the air-cooled chiller must be carefully checked, and the cause of the tripping must be checked and the correct handling must be completed. The brake can be closed.
3, if the air-cooled chiller exhaust high pressure and low water temperature troubleshooting, you need to press the manual reset button on the protection switch, and then press the stop switch before you can restart the operation.
4, suction ultra-low pressure, exhaust high temperature and small flow will automatically reset after troubleshooting, when the air-cooled chiller automatically reset, press the stop switch in order to reply to restart.
Air-cooled chiller series can be customized according to user requirements, such as air-cooled box chiller, air-cooled screw chiller, air-cooled low-temperature chiller and so on. When the unit is in operation, the chiller operator must record the unit's operating conditions and listen to the unit for noise at any time. When using six months or one year, cleaning the heat exchanger of the unit can ensure the normal and safe operation of the unit, and can prolong the service life of the unit.
[What should be paid attention to when shutting down the air-cooled chiller? 】East Yuejin series air-cooled chiller is a sealed box structure, the compressor, evaporator, condenser, automatic replenishment water tanks, pumps, frozen accessories, etc. are assembled together, the external powder paint chassis to protect them. The electrical control part of the unit and the control panel are on the chassis, and the operating status of the air-cooled chiller is clear at a glance.
