\n\tFailure of circulating pump\n<\/p>\n

\n\tThe failure of the circulating pump is generally the heat overload of the circulating pump. There are 4 main reasons for this failure:\n<\/p>\n

\n\t1. The external circulation pipeline is too long. It is suggested to shorten the external circulation pipeline, reduce the bending of the external circulation pipeline, and then click the Reset button of the electric cabinet surface heat relay;\n<\/p>\n

\n\t2. The circulating pipe is blocked. It is suggested to check the degree of cleanliness of the circulating pipe, install a filter, and then click the Reset button of the electric cabinet heat relay;\n<\/p>\n

\n\t3. The circulation pump voltage is too low. It is suggested to measure whether the circulation pump voltage is in line with the prescribed range, improve the voltage environment, and then click the Reset button of the electric cabinet heat relay;\n<\/p>\n

\n\t4. The regulating current of the heat relay is too small. It is suggested to measure the pump current, compare the heat relay range, turn up the heat relay current properly with the cross screwdriver, and then click the Reset button of the electric cabinet heat relay.\n<\/p>\n

\n\tFailure of sensor\n<\/p>\n

\n\tThe great possibility of sensor failure is the wiring error. At this time, check the wiring in time, and we should pay attention to two kinds of situations, one is the sensor is short-circuited or the temperature is < -160 \u2103, the other is the sensor is open circuited or the temperature is > 349\u2103.\n<\/p>\n

\n\tIf the sensor is short-circuited or the temperature is <-160 \u2103, it may be the fault of the sensor itself. At this time, change the sensor (there is a standby sensor in the equipment line slot), if the sensor connection is wrong, it is suggested to check the connection condition (the control circuit diagram) to correct.\n<\/p>\n

\n\tIf the sensor is open circuited or the temperature is > 349 \u2103, it should be the fault of the sensor itself. At this time, replace the sensor in time (there is a standby sensor in the equipment line slot). It is necessary to pay attention to whether the temperature is too high and beyond the range. If the equipment is out of electricity, check the power supply of the equipment.\n<\/p>\n

\n\tThe above two failures of the heating cooling circulator are relatively simple. I believe that you can quickly solve these failures with these tips.<\/p>","protected":false},"excerpt":{"rendered":"
