“High and low temperature test chambers have not been used for a few years, but the losses are particularly large.†In fact, the misconduct that we often overlook in daily use is to accelerate the “aging†of high and low temperature test chambers. The following is by Beijing Yashilin Testing Equipment Co., Ltd. The technical director will explain the most feared injuries of the high and low temperature test chambers.
High and low temperature test chamber door switch. Every day, the number of times the test box is opened should be minimized. Frequent opening of the door will increase the loss of cooling in the test chamber, affect the cooling effect, and increase energy consumption.
High and low temperature test chambers are deactivated for a long time. For some reason, there is no need to test, the user will choose to let the test box "rest", but the manufacturer reminds that it is generally not necessary to deactivate the test box for a long time, otherwise it will affect the life, and should be turned on for one hour at a time. This can greatly improve the life and performance of the test chamber.
High and low temperature test box power outlets are free to pull. When the test box is in normal use, the temperature in the test box reaches the set value, and the temperature controller automatically cuts off the power supply. At this time, the high and low pressures in the refrigeration system are balanced. For the compressor, the load is small and the motor is easy to be normal. start up. If the power supply is forcibly cut off, the power supply is immediately turned on when there is a relatively high pressure difference in the refrigeration system. The high voltage difference causes the motor load to be too large, and the starting current is 8 to 10 times the normal value, so that the current is too large. And the motor burned out. The manufacturer stressed that after the test box is powered off, it should wait for 3 minutes. After the high and low voltage of the refrigeration system reaches equilibrium, reconnect the power supply.
High and low temperature test chamber cleaning agent is not properly selected. When cleaning the test box, in order to prevent damage to the outer coating of the box and the stainless steel parts inside the box, do not use washing powder, decontamination powder, talcum powder, alkaline detergent, boiling water, brush, etc. to clean the inspection box to prevent damage to the tank or Pipeline. It is best to turn off the power, use a soft cloth dipped in water or dishwashing detergent, gently scrub, then wipe off the detergent with water. When cleaning, be careful not to touch the electronic components cleared by the inspection box to ensure safe use of electricity. After cleaning, plug in the power plug and check that the temperature controller is set to the correct position. The refrigerator is best once a month.
About 10 years ago, we were talking with our engineer about the future of caulking and the subject of the stone-age nature of the current caulking gun selection came up.
It seemed to us that the sealant,adhesive industry had moved ahead in so many ways, but tool design had been left behind. An idea was born to modernize the caulking gun.
