How to solve the problem of reactor cooling and heating system?

The reactor refrigeration and heating system is very important in the use of temperature control, so once the reactor refrigeration and heating system fails, remember not to rush, and work with relevant personnel to solve it slowly If the compressor of the reaction kettle refrigeration and heating system fails to start, Wuxi Guanya suggests to check whether the power supply is normal first If the power supply voltage should not exceed or be lower than the rated voltage of the unit, the commonly used voltage is 3-phase 380V, single-phase 220V When the voltage is too low or too high, the reactor refrigeration and heating system cannot be started For the compressor unit with water system, carefully check whether there is water in the cooling water system and chilled water system, whether the water pressure is normal, and whether the pipeline system of cooling water and chilled water is smooth Check whether all kinds of pressure gauges, thermometers, flow meters, solenoid valves, relays and energy regulating valves of the refrigeration and heating system of the reaction kettle are in good condition without failure, check whether the transmission device, if belt transmission is used, all kinds of protective devices are completely reliable, and whether all kinds of wrong tools and protective devices are complete and effective Check whether the valves of the high-pressure system and the low-pressure system of the refrigeration and heating system of the reaction kettle are opened and closed correctly during the start-up or operation Check the crankcase oil The oil level shall not be lower than or higher than the indicated oil level If the lubricating oil is not enough, add enough lubricating oil of the same specification and model Check whether the refrigerant system of the refrigeration and heating system of the industrial reaction kettle leaks and whether the lubricating oil system leaks Next, follow the steps to troubleshoot and check the main circuit first For example, whether the power supply is powered, whether the voltage is normal, whether the fuse has been burnt out due to starting overload, whether the air switch trips, whether the switch contacts are in good condition, and whether the power supply is lack of phase Observe the voltmeter and ammeter when the reactor refrigeration and heating system is started When the reactor refrigeration and heating system is not equipped with ammeter and voltmeter, use a multimeter or a measuring pen to check the power supply The compressor will not start when the power supply voltage is too low For the piston refrigeration compressor, whether the big end bearing bush and the bent sleeve of the connecting rod are locked These may be caused by the high exhaust temperature during the previous operation, or by the coking of lubricating oil, which causes the cylinder and piston to bond and makes the compressor unable to start Check differential pressure relay and high and low voltage relay When the oil pressure of the compressor is abnormal, the compressor can be stopped At the same time, when the discharge pressure and suction pressure of the compressor in the refrigeration and heating system of the reaction kettle are abnormal, the compressor cannot be started or the compressor will stop running soon after it has been started Check whether the cooling water volume, cooling water volume and water temperature of the reaction kettle cooling and heating system are normal If the water volume is small and the water temperature is high, the condensation pressure will rise sharply and the evaporation temperature will drop rapidly Because of the action of the unit protection facilities, the unit will be shut down quickly Check whether the electromagnetic valve and regulating valve related to the refrigeration and heating system of the reaction kettle fail, and whether they are opened or closed as required Check whether there is working medium leakage in the temperature sensing package of the temperature relay, or whether the adjustment is wrong Users use the refrigeration and heating system of Guanya reactor in Wuxi If there is a failure, don't worry We have a special after-sales team to solve the problem of equipment failure in time and effectively.
