General high and low temperature integrated machine valve repair detailed description
The conventional high and low temperature integrated machine valve replaces the packing, and the main function of the packing is to prevent the working medium from leaking along the axial direction of the valve stem. In case of minor leakage, the packing gland can be tightened. If the leak cannot be eliminated, the packing should be replaced. When replacing, the valve stem must be screwed out to the end. Use the filler needle to pull out the old packing, then screw the prepared new packing in...

Description of refrigeration principle in semiconductor wafer temperature control
In the operation of the semiconductor wafer temperature control refrigeration system, a state transition of a certain working fluid is used, and the necessary heat Q0 is extracted from the heat source of a lower temperature, and the heat Qk is sent to the heat source of the tropical heat through a storage process of the consumption power W. In this process, Qk = Q0 + W is taken from the conservation of energy. In order to achieve temperature control of semiconductor wafer temperature migratio...
Посмотреть деталиCold and hot shock constant temperature and humidity test chamber operation steps
When selecting the appropriate model of the LNEYA hot and cold shock constant temperature and humidity test chamber, you need to pay attention to the operation and installation steps. The user needs to be well prepared for the installation work. The hot and cold shock constant temperature and humidity test chamber should be noted before use. The power supply voltage should be turned on. After the fan is started, open the door and select the required impact height. Then close the door and pres...

Hybrid car battery test equipment cooling capacity description
Due to insufficient insulation thickness of the hybrid vehicle battery test equipment and pipeline or damage to the insulation layer, the loss of cooling capacity is increased, which affects the cooling effect. In the operation of the hybrid vehicle battery test equipment, once the outer surface of the insulation layer is found to have wet or frosted parts, it means that the thickness of the insulation material is insufficient or has been damp, and the insulation material should be added or r...

Fully closed cycle high viscosity fluid refrigeration heating flow control system
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...

Малый компрессор испытательной камеры для окружающей среды должен быть внимательным после обслуживания
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...

Поиск и устранение неисправностей высокотемпературного испытательного оборудования
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 ...

Ультра-высокая температура материала холодной и горячей ударной коробки холодильного масла
The ultra-high temperature material impact test chamber test device has too much frozen oil in the evaporator, which can also cause insufficient cooling and cause slow cooling. The oil stored in the evaporator of the ultra-high temperature material impact test chamber test device can be directly judged by the hot and cold boundary line of the oil surface. If the oil level is too high, it should be released in time. Some Freon and refrigerating machine oil dissolve each other. Therefore, when ...
