How To Vacuum The Ultra-Low Temperature Freezer Refrigeration System?
LNEYA ultra-low temperature freezer indoor and outdoor connection has been completed, observe the oil pump oil mark indication to see if there is enough oil, and then start the vacuum pump to see if it is normal. Then unscrew the large valve back cover nut and the fluorine injection nozzle nut, connect the pressure gauge low pressure, connect one end of the thimble to the refrigerant nozzle side, open the low pressure meter switch, vacuum, and quickly show that the vacuum is completed. It may...

Temperature Controller The temperature controller is used for control or protection of the unit. When the temperature reaches the set value, the switch automatically cuts off (or turns on) the circuit. In our products, temperature control is often used, water tank temperature to control the unit's start and stop. Some still require a temperature controller like antifreeze. The electromagnetic valve Shut off the system circuit when the compressor is stopped, to avoid liquid shock when the LNEY...

Analyse de la résistance statique du boîtier de batterie dans le système de test et d'analyse des batteries de puissance
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...

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...

Instructions relatives aux fuites internes des réfrigérateurs antidéflagrants à ultra-basse température
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...

Detailed explanation of closed circulation cooling system debugging attention
The preparation of the closed circulation cooling system before commissioning is an important part of the debugging process, which may affect the progress of the whole debugging process. Generally, attention should be paid to the leakage detection of the closed circulation cooling system air piping system, and the leakage of the closed circulation cooling system. There are detailed regulations for the quantity, which are roughly divided into high, medium and low pressure systems. Under differ...

Refrigeration control system compressor failure caused by oil pressure
If there is no oil pressure in the refrigeration control system, check the oil pump piping system connection for oil leakage or blockage. If the connection is loose, the joint should be tightened. If it is blocked, the oil pipeline should be cleared. Then check whether the compressor of the refrigeration control system is too large due to the opening of the oil pressure regulating valve or the valve core is detached. If the hydraulic pressure regulating valve of the refrigeration control syst...
