Classification and selection of high temperature preloaded disc springs
Measure and load the load of the combined disc spring on a testing machine with an accuracy of not less than 1%. (I≤10 pieces, butt combination) Use lubricant in the test, and the hardness of the pressure plates at both ends needs to be above 52HRC.
How to avoid freezing in the refrigerator
1. Preventive measures can be taken. For example, if the food is still steaming, it can't be put in directly. It can be put in only when it is cold. If you want to preserve fresh vegetables, wash them thoroughly, drain the water, wrap them in plastic bags or wrap them with plastic wrap, and then put them in. This can not only lock the water, but also help the use of the refrigerator, so as to avoid the problem of icing. 2. The refrigerator should be cleaned regularly, and after cleaning, a layer of cooking oil can be coated around to avoid freezing. Even if it freezes, it can be cleaned quickly.

What is a semiconductor refrigeration refrigerator
The conductor refrigeration refrigerator is a refrigerator that uses the semiconductor as the core cooling mode. Semiconductor refrigeration refrigerators are also called thermoelectric refrigeration refrigerators. The main part of such refrigerators is generally equipped with a water outlet, a water receiving tray beside the water outlet, and a heating element is generally arranged on the water receiving tray. When there is water on the water receiving tray, the circuit will heat the heating element, and the water on the water receiving tray can be evaporated in time. In the process of evaporating condensed water, electrical energy can realize the conversion of high-level energy to low-level energy, In turn, it will absorb a large amount of heat to achieve refrigeration.
What is the difference between a disc spring and a spring washer?
Disc spring is a conical disc spring that can withstand load, suitable for equipment with high temperature and high pressure or working pressure and temperature instability. It acts as a buffer, maintains the sealing performance, and protects the stud from fatigue damage caused by overload. The surface of the disc spring is serrated, which can play a locking role. Elastic compensation increases frictional resistance, prevents loosening, and keeps the bolt in a good locking state for a long time.
