低温循環装置の霜付きを解決するには？
The failure of the low temperature circulation device frosting is mainly because the compressor return air temperature is too low, which may be that the throttle valve liquid refrigerant supply is in a normal state in the low temperature circulation device, but the low temperature circulation device evaporator cannot normally absorb the heat supply refrigerant expansion; It may also be because the evaporator is in a normal working state but the refrigerant supply throttle valve is too large, ...

Motor test chiller compressor causes wear
Motor testing chiller oil quality may be one of the main reasons affecting crankshaft wear. If the engine oil is used in the chiller refrigeration system, the engine oil that does not meet the requirements and is of poor quality may cause crankshaft wear. High-speed multi-cylinder compressors have high requirements for the quality and lubrication performance of the motor test chiller oil due to high speed, high load and high exhaust gas temperature. Motor test chiller refrigeration compressor...

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...

リニア急速温度変化テスターの空充填手順
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...

完全クローズドサイクル高粘度流体冷凍加熱流量制御システム
Application:1. The tested object is connected to a test platform adapter.2. The internal parts of the parts are cooled, heated, flow controlled, and pressure controlled by various lubricating oils, hydraulic oils, aviation fuel, fuel oil, and coolant.3. The test component needs to go through a specific temperature profile and record the change in temperature.4. When conducting the tolerance test, perform the thermal shock test, and the rapid temperature drop control usually takes place in...

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...

高温試験装置関連のトラブルシューティング
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 ...
