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...

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...

Small environmental test chamber compressor should pay attention after maintenance
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...

High temperature test equipment related troubleshooting
The high temperature test equipment is mostly caused by water shortage in the water circulation. This way, the purified water is replenished to the water tank until the water level meter on the lower right side of the water tank reaches about 80% of the entire scale. Every equipment will be fully commissioned before shipment. During the commissioning process, we have done ample tutorials for each internal system. If the equipment is in transit, due to up and down vibration, the float and the ...

Glycol chiller installation requirements
In the summer, the use of glycol chillers is relatively frequent. Efficient glycol chillers are also needed. Therefore, when installing glycol chillers, they need to be installed on a smooth and tidy floor. Why choose a smooth ground when installing? Users who have known the glycol chiller should know that if the glycol chiller is tilted during installation, it may cause the refrigerant or cooling water or chilled water to operate abnormally, and the refrigerant may flow backward or the resis...

The reason why the semiconductor small thermostat is blocked by refrigeration
The small semiconductor small-scale thermostat ice jam is mainly caused by the excessive moisture contained in the refrigeration system. With the continuous circulation of the refrigerant, the moisture in the refrigeration system gradually collects at the capillary outlet, in view of the relatively low temperature at the capillary outlet, the water It forms ice and gradually increases. When it reaches the necessary level, the capillary is completely blocked, the refrigerant does not recur, an...
