How to judge the cooling effect of the cryogenic refrigerator?
It is important to understand the performance of a cryogenic refrigerator, both good and bad, to understand its cooling effect. How to judge its cooling effect together and Xiaobian down to see it! Cooling effect To understand the cooling effect of a cryogenic refrigerator, it is important to see if it can achieve the temperature effect required by customers in a short time. Generally speaking, the temperature range required by each customer is different. If the required temperature is requir...
View detailsHow to deal with the frosting of the chiller?
There are many types of chillers, and customers familiar with this piece are definitely familiar with the chiller. For the frosting of the chiller, many people are ignorant, and then let's learn more about it with LNEYA! 1. If it is a chiller, please check if the opening degree of the expansion valve is too large. The small point can be fine-tuned (if it is an electronic expansion valve adjustable circuit control panel). 2. If the opening degree of the expansion valve is too small or blocked,...

Installation points of cryopumps in cryogenic refrigerators
In the construction of the cryogenic refrigerator, the cryopump is a must. The low temperature freezer manufacturer LNEYA tells everyone that the cryopump should be operated according to the requirements when it is installed. Installation facilities and requirements: The foreline pump—the cryopump requires a pre-stage pump pre-vacuum chamber to draw the start-up pressure of the cryopump and to remove the gas generated during regeneration when the cryopump is regenerated. Adsorption well—Insta...

Misunderstanding about the operation of the factory boiler
The boiler is a very common equipment in the factory. LNEYA Xiaobian tells everyone that many people have misunderstandings about it. Misunderstanding 1 The higher the steam pressure, the better. The choice of boiler steam pressure depends mainly on the needs of the user. The steam pressure is low, the safety of the pressure-bearing parts is favorable, the energy consumption is also low, and the steam pressure is too high, the energy consumption is high, the corresponding steam equipment, the...
