Protection device details of circulating fluid temperature control device
The circulating pump overload protection function is to cut off the main power of the circulating pump when the circulating liquid temperature adjustment device is too large. Press the green button when resetting; the red button is the stop button, which is used during the test. When frequent protection, please check whether the voltage is under voltage (undervoltage is less than 15%, the power protector is not working), undervoltage is increased into current, forming protection. At this time...

LNEYA high and low temperature heating refrigerator maintenance instructions
High and low temperature heating refrigerators use circulating water to replace circulating water regularly every month. If heat transfer oil is used, heat transfer oil should be replaced periodically every six months to one year. When the high and low temperature heating refrigerator is used for more than 150 degrees for a long time, check the heat transfer oil every three to six months, and decide whether to replace it according to the actual situation. When replacing the circulating oil, d...

Why is there air in the reactor temperature control system?
The impurity gas in the reactor temperature control system is to increase the condensing pressure of the refrigeration system, thereby increasing the condensing temperature, increasing the exhaust temperature of the compressor, increasing the power consumption, reducing the cooling efficiency, and possibly the exhaust gas temperature is too high. The carbonization of the lubricating oil affects the lubrication effect, and in severe cases, the refrigeration compressor motor is burnt. The gas g...

When the explosion-proof type hot and cold integrated machine is used at the end of the day or when it is not used by the standby, be sure to disconnect the cooling water connection pipe, clean the remaining cooling water in the pipe, and store it in a dry place to prevent freezing and expansion. Damage to machine parts (such as coolers, pumps, connecting copper pipes). The method of removing residual water is as follows: 1. The water sequence series needs to disconnect the cooling water and ...

High temperature test equipment related troubleshooting
The high temperature test equipment is mostly caused by water shortage in the water circulation. This way, the purified water is replenished to the water tank until the water level meter on the lower right side of the water tank reaches about 80% of the entire scale. Every equipment will be fully commissioned before shipment. During the commissioning process, we have done ample tutorials for each internal system. If the equipment is in transit, due to up and down vibration, the float and the ...

Ultra-high temperature material cold and hot impact box refrigeration oil
The ultra-high temperature material impact test chamber test device has too much frozen oil in the evaporator, which can also cause insufficient cooling and cause slow cooling. The oil stored in the evaporator of the ultra-high temperature material impact test chamber test device can be directly judged by the hot and cold boundary line of the oil surface. If the oil level is too high, it should be released in time. Some Freon and refrigerating machine oil dissolve each other. Therefore, when ...

Characteristics of the evaporator of LNEYA screw chiller
The amount of cooling capacity of the screw chiller is directly related to the energy consumption and operational economics of the entire unit, which is worthy of attention. Especially when designing a cold station, there is no single chiller in the general situation. This is mainly because when the screw chiller fails or is shut down for maintenance, it will not stop production. Instead, the reasonable unit should be selected according to the production situation. The number of units. When t...
