Analysis of Common Failures of Adhesive Tape Holding Tester The product is produced and sold by Dongguan Tesite Detection Instrument Co., Ltd. More product details please call 0769-89293129 to inquire about ~~ Four common failures of tape holding viscosity tester : 1 , in the high temperature test, if the temperature change does not reach the test temperature value, you can check the electrical system, remove the fault one by one. If the temperature of the constant temperature and humidity test chamber rises very slowly, it is necessary to check the wind circulation system to see if the adjustment baffle of the wind circulation is normally open, and conversely, check whether the motor operation of the wind circulation is normal. If the temperature overshoots badly, then you need to set the PID setting parameters. If the temperature rises directly, over-temperature protection, then the controller fails and the control instrument must be replaced. 2. When the temperature of a constant temperature and humidity test box does not reach the target of the test, you must observe the change in temperature. It is a very slow temperature drop. After the temperature reaches a certain value, the temperature rises. The former must be checked. Whether the studio is to be dried before the low-temperature test, so that the studio is kept dry, and then the test sample is put into the work chamber and then tested. Whether the test sample in the work chamber is placed too much and the wind in the work chamber cannot be fully cycled. After eliminating the above reasons, it is necessary to consider whether it is a fault in the refrigeration system. In this case, the manufacturer's professional personnel must be inspected and repaired. The latter phenomenon is caused by the poor use environment of the constant temperature and humidity chamber equipment. The ambient temperature of the equipment and the location of the equipment ( the distance between the cabinet and the wall ) must meet the requirements ( in the equipment operation and use instructions) ) . 3 , tape holding viscosity testing machine in the heat test, the actual humidity will reach 100% or the actual humidity and the target humidity is very different, the value is much lower, the former phenomenon: may be caused by dry gauze on the wet ball sensor, It is necessary to check whether the water tank in the wet ball sensor is short of water. The water level in the water tank is automatically controlled by a water level controller. Check whether the water supply system of the water level controller is normal and whether the water level controller is working properly. Another possibility is that the wet ball gauze may cause the gauze to become hard due to the long use time or the purity of the water supply, so that the gauze cannot absorb the moisture and dry, and the above phenomenon can be eliminated only by replacing or cleaning the gauze. The latter phenomenon is mainly due to the fact that the humidifying system of the constant temperature and humidity test box is not working, the water supply system of the humidifying system is checked, whether there is a certain amount of water in the water supply system, whether the water level control of the humidifying boiler water level is normal, and whether the water level in the humidifying boiler is normal . If all of the above is normal, then check the electrical control system, which requires professional maintenance personnel to perform the repair. 4. When the equipment suddenly fails during the test operation, a corresponding fault display prompt appears on the control instrument and there is an audible alarm. The operator can quickly check which type of fault belongs to in the troubleshooting section of the operation of the equipment, and the professional can quickly eliminate the fault to ensure the normal operation of the test. Other environmental test equipment will have other phenomena in use, it must be specific phenomena, specific analysis and exclusion.
