The importance of car cooling water cycle maintenance
Even if the overall running quality of the car cooling water circulation machine is high, if there is no maintenance and maintenance in the specified time, the car cooling water circulation machine may have different degrees of failure. Especially for many automotive cooling water circulation machines, after a long-term operation, a large scale problem will occur. If the scale cannot be effectively cleaned, after a long period of accumulation, the scale of the scale is continuously expanded, ...

Causas de la reducción del efecto de transferencia de calor de los refrigeradores verticales de temperatura ultrabaja
If the outer frost layer of the vertical ultra-low temperature refrigerator is too thick or excessively dusty, it may cause the external temperature of the equipment to be mostly lower than 0, resulting in low heat transfer efficiency of the evaporator. Because the vertical ultra-low temperature refrigerator has relatively high humidity, the moisture in the air is easy to frost on the surface of the evaporator, and even freezes, which affects the heat transfer effect of the evaporator. In ord...

¿Cómo juzgar la calidad de la tubería de tratamiento de gases residuales de galvanoplastia?
Generally, when purchasing the electroplating waste gas treatment equipment, it is necessary to observe the appearance of the copper tube to judge. The first is to look at the color of the copper tube. According to the type of copper tube purchased, different colors are judged, such as a copper tube, and the red color of the general color is reddish. It is good copper. Brass tubes, generally lighter in color, are better. There is also a layer of zinc on the copper, some galvanized, and the co...

Fallo por alta presión de un refrigerador criogénico de acero inoxidable
At the high speed of the stainless steel cryogenic refrigerator compressor, the temperature rises and the compressor generates high air pressure, which causes the high voltage protection relay to operate. The discharge pressure of the compressor reflects the condensing pressure. The normal value should be 1.3~1. 7MPa, and the protection value of the Wuxi Guanya stainless steel cryogenic refrigerator is set to 2.1MPa. Then, if it is a long-term work, the compressor pressure is too high, which ...

How to choose the lubricant for the injection molding machine?
The injection molding machine cooling system lubricating oil needs to pay attention to the type of compressor when selecting. The compressor has three types: piston type, screw type and centrifugal type. The first two kinds of lubricating oil are in direct contact with the compressed refrigerant, and the lubricating oil should be considered. The problem of interaction between the refrigerant and the refrigerant. The lubricating oil used in the centrifugal injection molding machine cooling sys...

Linear rapid temperature change tester emptying and filling instructions
Before starting the linear rapid temperature change tester, check whether the relevant protective measures are in place, such as fire protection, protection, leak prevention and other tools. Check whether the power supply is in place according to the power supply installation and equipment grounding, whether the phase sequence is correct, and whether the grounding is good. Then power on the equipment, and then check whether the relevant valve is open. Otherwise, the circulating pump will be b...

Start-up work for new energy thermal management
In the pipeline selection of new energy thermal management, if the use of improper/damaged hoses and/or hose joints will result in injury, the new energy thermal management is limited by the temperature, caliber, installation method, etc. Tube, metal insulation hose temperature range -60 ~ 250 ° C; pressure ≤ 2.5 bar. When the new energy thermal management configures the metal insulation hose and other pipelines carefully, when referring to its pressure and overpressure capability, caliber an...

El pequeño compresor de la cámara de pruebas ambientales debe prestar atención después del mantenimiento
In the centrifugal small-scale environmental test chamber, the suction recovery device is generally an independent system, and if necessary, the pipeline connected to the condenser and the evaporator can be closed for separate maintenance. After replacing the compressor in the small environmental test chamber, the pumping recovery device generally uses the automatic mode to open, stop and work during the operation of the unit. Therefore, the oil level of the oil separator of the piston compre...
