Dongguan Kewen Test Equipment Co., Ltd. is a high-quality manufacturer specializing in the production of high-low temperature impact test chambers. High-low temperature impact test chambers are mainly used to test the material structure or conform to materials, and are subjected to extreme high and low continuous harsh environments in an instant. The extent to which it can tolerate is to test the chemical changes or physical damage caused by the thermal expansion and contraction in the shortest possible time. Applicable objects include metals, plastics, electronics, optoelectronics, communications and other materials; they can be used as references and references for product improvement.
With regard to the simple breakdown of the high-low temperature impact test chamber, today Kevin discusses the following equipment maintenance methods:
First, in the high temperature test, if the temperature change does not reach the test temperature value, you can check the electrical system and eliminate the fault one by one. If the temperature rise is very slow, you must check the wind circulation system to see if the wind adjustment baffle is open On the other hand, it is necessary to check the settings of the PID for a long time by checking whether the motor operation of the air circulation is normal, such as excessive temperature overshoot. If the temperature rises directly, over-temperature protection, then the controller fails and the control instrument must be replaced.
Second, the low temperature can not reach the test standard, then you must observe the temperature changes, is the temperature drop is very slow or after the temperature has risen to a certain value, the temperature has a tendency to pick up, the former must check, do low temperature test will work Room drying, so that the work room's wind can not be fully cycled, after eliminating the above reasons, we must consider whether it is a failure in the refrigeration system, so we must ask a long-term professionals to repair, the latter phenomenon is the use of equipment The environment is not good, the ambient temperature of the equipment is placed, and the location (the distance between the cabinet and the wall) must meet the requirements (in the operating instructions of the equipment).
Third, the high-low temperature impact test box suddenly appeared failure rate during the test operation, the control instrument appeared on the corresponding fault prompts and voice alerts. The operator can quickly check which type of fault belongs to in the troubleshooting chapter of the operation of the equipment, and then the manufacturer's professional can quickly eliminate the fault to ensure the normal operation of the test. Other environmental testing equipment will be maintained during use. The condenser of the refrigeration system shall be regularly cleaned. The oil shall be lubricated according to the instructions for the moving parts, and the maintenance and inspection of the electrical control system shall be conducted. These tasks are indispensable.
Fourth, in the heat test, the actual humidity will reach 100% or the actual humidity and the target humidity are very different, the value is much lower, the former phenomenon; may be caused by dry gauze on the wet ball sensor, then check the wet ball sensor Whether the water in the sink is short of water, the water level in the water tank is automatically controlled by a water level controller, check whether the water level controller water supply system is normal, whether there is a certain amount of water in the water supply system, control whether the water level of the humidification boiler is normal, and the humidification boiler Whether the water level in the water is normal or not, if all of the above are normal, check the electrical control system. This should be done by professionals.
Since the establishment of Dongguan Kewen Test Equipment Co., Ltd., a group of professional and technical elites have been trained. All equipment of the company can be shipped to the customer's location after commissioning. The whole machine warranty is for one year. If there is any failure and replacement in the following year, All spare parts are replaced free of charge. Even if the failure rate after replacement of the equipment is reported after the following year, parts must be replaced. Our company will charge a reasonable amount according to the market price of spare parts. Look forward to working with friends and friends.
