Faults and Treatment of Brazed Radiator Frost Cracking
Brazed Radiator manufacturers generally run in cold weather, due to lower temperatures, Brazed Radiator is easy to crack, affecting the entire air conditioning system, to the enterprise caused unnecessary economic losses. Here, a few common Brazed Radiator manufacturers Brazed Radiator cracking failure and treatment to do a brief introduction.
1. The temporary pipeline is not rinse the Brazed Radiator manufacturers water supply
Some enterprises in order to rush often with Brazed Radiator manufacturers for temporary heating, but because of the urgency of the entire heating system is not formal water rinse, for the return pipe all the use of the next branch pipe connection, the results of pipeline dirt in the distance Heat exchanger station near the Brazed Radiator manufacturers continue to silt deposition, hot water flow continues to decrease, resulting in heater cracking. In essence, the temporary water supply pipeline construction is not washed according to the construction procedures and blindly into the use of the heater caused by cracking.
2. The valve position indicated by the self-control valve is incorrect
Sometimes brazed radiator manufacturers automatic control system before the Brazed Radiator manufacturers to normal operation, but after the opening of a freezing accident occurred. This is because the installation of misuse of the Brazed Radiator manufacturers water valve opening and closing instructions and automatic control system, computer instructions just the opposite, Brazed Radiator manufacturers water supply is automatically controlled by the system to stop the state, causing accidents. Therefore, when the outdoor temperature dropped below 0 ℃, should try to keep the air conditioning system stable operation, water system, automatic installation and commissioning should be arranged in other seasons to avoid accidents caused by debugging errors.
3. Brazed Radiator manufacturers in winter when the water cooler in the water
Sometimes in the basement of the Brazed Radiator manufacturers have been disabled after the occurrence of the surface cooler freezing accident, mainly due to Brazed Radiator manufacturers inside the surface cooler caused by water, in the Brazed Radiator manufacturers for the water supply riser The highest point of the additional DN15 vent pipe, Brazed Radiator manufacturers can be used when deflating and discharging, in particular, can ensure the thoroughness of the discharge; in the Brazed Radiator manufacturers for the supply of water pipes on the addition of a set of valves, Completely cut off the slow down after the discharge of the problem.
4. Brazed Radiator factory-controlled anti-freeze protection device in the manual adjustment of the heater flow out of control
Fresh air conditioning unit winter operation must ensure that the rated water flow, heater water flow is too small will lead to freezing accident. Winter cold weather, the basement of the air conditioning load is small, when the operator found that the room temperature is too high, due to eager to reduce the temperature, the Brazed Radiator manufacturers water flow immediately transferred very low, then Brazed Radiator manufacturers Frost protection device failure, if the outdoor temperature below 0 ℃, it is prone to heater cracking accident.
The above four Brazed Radiator manufacturers Brazed Radiator cracking failure are the operator in the construction, commissioning, operation process caused by negligence, green special air to remind you, in the Brazed Radiator manufacturers related operations, must Pay attention to the details of inspection and use, if necessary, can use fans, electric heaters, duty fans and other facilities to prevent Brazed Radiator manufacturers heater crack, to ensure the safe operation of Brazed Radiator manufacturers.
