Die Bedeutung der Wartung des Kühlwasserkreislaufs von Kraftfahrzeugen
Selbst wenn die allgemeine Betriebsqualität der Autokühlwasserzirkulationsmaschine hoch ist, kann die Autokühlwasserzirkulationsmaschine in unterschiedlichem Maße ausfallen, wenn keine Wartung und Instandhaltung in der vorgegebenen Zeit erfolgt. Vor allem bei vielen Kühlwasserkreislaufmaschinen für Kraftfahrzeuge kommt es nach langem Betrieb zu einem großen Ablagerungsproblem. Wenn der Kesselstein nicht effektiv gereinigt werden kann, wird der Kesselstein nach einer langen Zeit der Akkumulation kontinuierlich erweitert, ...

Ursachen für die verringerte Wärmeübertragungswirkung von vertikalen Ultratiefkühlschränken
Wenn die äußere Frostschicht des vertikalen Ultratiefkühlschranks zu dick oder übermäßig staubig ist, kann dies daran liegen, dass die Außentemperatur des Verdampfers meist unter 0 °C liegt, was zu einer geringen Wärmeübertragungseffizienz des Verdampfers führt. Da der vertikale Ultra-Niedrigtemperatur-Kühlschrank eine relativ hohe Luftfeuchtigkeit aufweist, kann die Feuchtigkeit in der Luft leicht auf der Oberfläche des Verdampfers gefrieren, was den Wärmeübertragungseffekt des Verdampfers beeinträchtigt...

How to judge the quality of the pipeline for electroplating waste gas treatment?
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...

Hochdruckversagen eines Tiefkühlschranks aus rostfreiem Stahl
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 ...

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...

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...

Details der Schutzvorrichtung einer Vorrichtung zur Regelung der Temperatur einer zirkulierenden Flüssigkeit
The circulating pump overload protection function is to cut off the main power of the circulating pump when the circulating liquid temperature adjustment device is too large. Press the green button when resetting; the red button is the stop button, which is used during the test. When frequent protection, please check whether the voltage is under voltage (undervoltage is less than 15%, the power protector is not working), undervoltage is increased into current, forming protection. At this time...
