The power supply of the vacuum drying equipment with voltage transformation method shall be inserted and arranged for the special purpose of the equipment, and it is prohibited to connect any electrical equipment irrelevant to the equipment.

Do not connect other equipment or lines to the control cabinet or components of the equipment.

It is forbidden to place any objects in the control cabinet to avoid fire, short circuit, electric shock and other risks.

Prevent non professionals from opening the door of the control cabinet during the operation of the equipment to avoid electric shock.

Do not change the setting value of each time relay in the control cabinet.

If it is found that the heating ammeter still shows the value when the program does not command the system to heat, check whether the touch device is damaged immediately. If the touch device is damaged, replace it immediately; If one or two ammeters are found to have no value during heating, check whether the fuse is damaged immediately. If the fuse is damaged, replace it in time.

Vacuum dryer is a kind of conduction heat transfer dryer. The materials do not touch directly with the heating medium, but are used to dry a small amount of mud and paste materials that are not resistant to high temperature and easy to oxidize, with a moisture content of 15% ~ 90%. The blades of the capacity rake agitator in the dryer are made of cast iron or steel and installed on a square shaft. 50% of the blades are oriented to the left and the other 50% to the right. The speed of the motor is 8R / min, and the speed of the motor is 8R ~ min. Moreover, the automatic steering assembly is selected to change the rotation policy of the shaft and the rotation policy of the agitator every 5 ~ 8min. The vacuum dryer has the advantages of simple layout, convenient operation, long service cycle, stable function, small steam consumption, strong useful function and good product quality. It is especially used for paste materials that are not resistant to high temperature, flammable and easy to oxidize under temperature regulation.

Filter the high viscosity oil that cannot be filtered by the general oil filter. It is a new generation of plate and frame pressure filter. For the occasion where only mechanical impurities need to be filtered, the machine is more flexible, convenient, low cost and high precision than the vacuum oil filter. It is more useful and has a long service life than the general pressure filter. It can reduce the consistency under constant temperature heating without replacing the filter paper. The filtering precision is high and stable.

Therefore, JL series light filter is widely used in electric power, manufacturing, automobile, railway, exercise, steel rolling, aviation, industry and mining. It can deeply filter hydraulic oil, turbine oil, mechanical oil, tightening oil, spindle oil, insulating oil and all liquid oil with smooth function, but it is not allowed to filter alcohol, gasoline and other liquids without smooth effect and flammable.

Small leakage and micro leakage of vacuum oiling equipment are difficult to check. The commonly used method is to use the ionization tube to detect leakage with sensitive response to some gases under high vacuum, such as acetone or ethanol. Use a medical syringe to spray acetone or ethanol into suspicious places. When it is sprayed to the leakage point, the pointer of the ionization meter will swing significantly. In this way, we must be patient and be more stable than the indication of the ionization meter, that is, the extraction capacity and leakage rate of the vacuum unit are balanced before eruption. Repeat several times to confirm the leakage point. Zhc-1 appearance can also use the above methods to detect leakage. The difference is that zhc.1 appearance can detect leakage within the working range of rotary vane pump, and is not afraid of exposure to the atmosphere.
