Relazione tra scarse prestazioni di refrigerazione e refrigerante in ambienti industriali a basse temperature
The effect of the refrigeration system of the low-temperature industrial refrigerator is directly related to the refrigerant. Once the refrigerant leaks, the cooling capacity will be insufficient, so that the suction and exhaust pressures are relatively low, and the expansion valve and the evaporator are in operation. The balance pressure cannot be maintained. Therefore, if the refrigerant leaks from the low-temperature industrial refrigerator (group) is found, it is not rushed to fill the sy...

Analisi della resistenza statica della scatola della batteria nel sistema di test e analisi delle batterie di potenza
The battery box of new energy vehicles is one of the core components of electric vehicles. Designing high-strength, high-rigidity, high-security, high-lightweight battery boxes is of great significance to the development of electric vehicles. Overly simplified battery box models will lead to The severe distortion of the response, which in turn affects subsequent structural optimization. In order to accurately analyze the structural response of the battery box, the internal components of the b...

Explosion-proof ultra-low temperature refrigerator internal leakage instructions
1. Sound leak detection method: First, the refrigeration pipeline of the explosion-proof ultra-low temperature refrigerator is filled with nitrogen. Then use a stethoscope to check the interior. When you hear a leak in a certain area, mark it. Carefully pry open the metal plate at that place, check the leak point of the pipe with thick soapy water, repair by repair welding or gluing, fill the foaming agent, fill the mouth with a larger metal plate, and glue the four sides. . This method is in...

New energy power car power battery detection system vacuum description
The new energy power vehicle power battery test checks the vacuum pump switch in the closed state before operation; when the vacuum pump is placed horizontally, ensure that the lubricating oil and the oil level line are kept horizontal; whether the sealing rubber pad is damaged; whether the pressure gauge needle is returned to zero. Place the vacuum pump on the indoor floor (safe, stable, and easy to operate). It is forbidden to be placed outdoors, and it is not allowed to be placed on the po...

Low temperature circulating chiller startup and shutdown operation
When the low temperature circulating chiller is turned on, it can be automatically turned on when the manual start is selected. The automatic start-up needs to open the compressor exhaust shut-off valve, start the cooling water pump and the coolant pump, press the compressor start button, then the oil pump is automatically put into operation. The spool automatically returns to the “0” position. After the oil pressure difference is established, the main motor is automatically started after a d...

The effective operation of low temperature freezer is relevant to the needed refrigerating effect. It is crucial to correct expansion valve if better cooling effect is wanted. So, how to debug the expansion valve of low temperature freezer?During the operation of low temperature freezer, the smaller the opening is, the less the volume of fluid transmission and pressure are,and vice versa. Based on the thermodynamic property of refrigerating fluid, the corresponding temperature varies as the p...
