Daily maintenance method of high and low temperature thermal shock chamber

High and low temperature thermal shock chamber is also called high and low temperature impact test chamber, it is a machine and equipment with alternating hot and cold cycles to test. The cycle speed of this test chamber can be fast or slow, and it has many functions and is also very powerful. Therefore, as a operator and user, in addition to mastering the characteristics of the test chamber, it is also necessary to know its daily maintenance methods. Next, let’s take a look at the relevant introduction.

First, the radiator (condenser) of the high and low temperature thermal shock chamber refrigeration unit should be maintained regularly and kept clean. Dust slimy condenser will make the compressor high-pressure switch jump off and produce false alarm, the condenser should be regular monthly maintenance, the use of vacuum cleaner will be the condenser on the heat dissipation mesh attached to its dust suction or after booting use a hard brush or blow dust with a high-pressure nozzle.

Second, when the high and low temperature thermal shock chamber opens and closes the door or takes the test material from the furnace, the item must not be in contact with the rubber edge on the door to prevent the rubber edge from being destroyed and shorten the life, and the ground around and at the bottom of the fuselage should be kept clean at any time to avoid a large amount of dust inhaled into the unit to produce accidents and reduce performance.

Third, high and low temperature thermal shock chamber refrigeration system is the core of this machine, please check once a year all copper pipes have leaked snow conditions, each cough joint, welding port, if there is oil leakage, please notify the company or directly deal with it. The large current contact of the switchboard, the distribution room is cleaned and repaired at least once a year, and the loosening of the contact will make the entire equipment in a dangerous working state, and the light will burn out the components, and the heavy fire, alarm, and personal injury are very dangerous. When cleaning, use a vacuum cleaner to remove indoor dust.

Fourth, the two over-temperature protector setting values of the high and low temperature thermal shock chamber. Please do not debug casually, the factory has been adjusted, this protection switch is to protect the heating tube from empty burning and alarm. Set point = temperature set point 20 °C ~ 30 °C.

Fifth, high and low temperature thermal shock chamber when the test product time arrives to take the product, it must be in the shutdown state and the staff must wear dry, anti-electricity, temperature-resistant gloves to pick up and place the product. High and low temperature impact on the cleaning and maintenance of the inside and outside of the box. In addition, the high and low temperature impact box should first remove the internal impurities (substances) before operation.

The above five points are the daily maintenance methods of the high and low temperature thermal shock chamber, and the cleaning of the inside and outside of the test chamber must also be paid attention to, at least to maintain more than once a year with clean water wipes.

LISUN lauched High and Low Temperature Thermal Shock Chamber can be used in the temperature shock test and fast-changing temperature test in a wide range such as aviation, air space, electronic components and material research.
