High and low temperature impact test maintenance and maintenance methods The high and low temperature impact test is also called high and low temperature impact test box or high and low temperature impact test. It is a high-precision, high-performance environmental test equipment. High and low temperature impact test In order to make the high and low temperature impact test you use have better working efficiency and longer service life, Guangdong Sili Test Instrument Co., Ltd. reminds you to refer to the following daily maintenance requirements and principles of high and low temperature impact test! 1. Maintenance must implement the principle of "emphasis on maintenance and prevention, and prevention as the first priority". Regular maintenance and compulsory maintenance must be carried out to properly handle the relationship between use, maintenance, and repair.
2. In order to ensure that the mechanical equipment is always in a good technical state, it can be put into operation at any time, reduce the number of downtimes, improve the mechanical integrity rate and utilization rate, reduce mechanical wear, extend the service life of the machinery, reduce the cost of machinery operation and maintenance, and ensure safe production. The maintenance of high and low temperature impact test equipment must be strengthened;
3. Each team must do a good job of maintaining all types of machinery according to the mechanical maintenance regulations and maintenance categories. There can be no unreasonable delay. In special cases, the maintenance can only be postponed after being approved by the special manager, but generally it should not exceed half of the specified maintenance interval;
Fourth, high and low temperature impact test maintenance machinery must ensure the quality, carried out item by item according to the prescribed items and requirements, no warranty is omitted or not guaranteed. Maintenance items, maintenance quality and problems found in maintenance should be recorded and reported to the special staff of this department;
1. The high and low temperature impact test freezing system is the core of the test box. Every year, all copper pipes must be inspected for leaks and snow conditions. The joints and welding ports of the horns, if there is oil leakage, please directly handle or know Our company 2. When opening or closing the door or taking the test object from the furnace, do not allow the object to contact the rubber edge of the door to prevent the rubber edge from being damaged and shortening the life.
3. The ground around and at the bottom of the fuselage should be kept clean at all times to avoid accidents and performance degradation caused by a large amount of dust being sucked into the unit.
4. The radiator (condenser) of the refrigeration unit should be regularly maintained and kept clean. The dusty and sticky condenser will cause the compressor high-pressure switch to trip and generate a false alarm. The high and low temperature impact test condenser should be regularly maintained monthly, using vacuum The vacuum cleaner absorbs the dust attached to the condenser cooling mesh or uses a hard brush to clean the dust after turning it on.
5. The high-current contacts of the switchboard should be cleaned and repaired at least once a year in the distribution room. The loosening of the contacts will put the entire device in a dangerous working state, and the components will be burned out in light, and the fire, alarm and personal injury will be very dangerous. Use a vacuum cleaner to remove indoor dust.
6. Please do not debug the setting values ​​of the two over-temperature protectors in the distribution box. They have been adjusted at the factory. This protection switch is used to protect the heating tube and humidification tube from empty burning and water shortage alarm. High and low temperature impact test Set point = temperature set point + 20 ℃ ~ 30 ℃
7. Waterway inspection and maintenance, waterway water pipe is a device that is easy to block and leak, please be sure to regularly check for water leakage and water blocking phenomenon, if any, please eliminate or notify our company in time.

Maintenance items, maintenance quality and problems found in maintenance should be recorded and reported to the special staff of this department;
Fifth, the maintenance personnel and the maintenance department should achieve "three inspections and one handover (self-inspection, mutual inspection, full-time inspection and one-time inspection)", constantly sum up maintenance experience, and improve maintenance quality.
