1. Vacuum box shell must be effectively grounded to ensure the use of safety.
2. The vacuum box should be in the relative humidity ≤ 85% RH, non-corrosive gas around, no strong vibration source and the presence of strong electromagnetic field environment.
3. Vacuum box studio without explosion, anti-corrosion and other treatment, shall not be flammable, explosive, easy to produce corrosive gas items dry.
4. Vacuum pump can not work for a long time, so when the vacuum to dry goods requirements, should first turn off the vacuum valve, and then turn off the vacuum pump power, when the vacuum is less than dry items, then open the vacuum valve and vacuum pump power, This extends the life of the vacuum pump.
5. Dry items such as moisture, then the vacuum box and the vacuum pump is best to join between the filter, to prevent moisture into the vacuum pump, causing vacuum pump failure.
6. Dry items such as dry and changed to light weight, small size (for small particles), should be working in the vacuum suction port plus blocking network to prevent damage to the dry matter inhalation vacuum pump (or solenoid valve).
7. After repeated use of the vacuum box, can not produce vacuum phenomenon, this time should replace the door seal or adjust the box door buckle out distance to solve.When the vacuum box drying temperature is higher than 200 ℃, will Resulting in slow leak phenomenon, then open the box behind the cover with an Allen wrench to loosen the heater base, replace the seal or tighten the heater base to solve.
8. Release valve rubber stopper if the rotation is difficult, can be coated with the right amount of grease lubrication (such as Vaseline)
9. In addition to maintenance, can not open the left side of the box cover, so as not to damage the electrical control system.
10. Vacuum boxes should always be kept clean. Do not use the door glass glass with a chemical reaction solution, wipe with a soft cotton cloth.
11. If the vacuum box is not used for a long time, the exposed parts of the plating will be wiped with neutral oil to prevent corrosion, and put on the plastic film dust cover, placed in a dry room, so as not to damage the electrical components, use.
12. Vacuum box without continuous use of the suction, you should first close the vacuum valve, and then turn off the vacuum pump power, or vacuum pump oil to pour into the box.
Vacuum drying oven composition and working principle:
Electrostatic vacuum oven shell by the sheet metal stamping folding, welding molding, shell surface using high-intensity electrostatic spray coating process, the film is smooth and firm.The studio is made of carbon steel or stainless steel plate folding welding, the studio and the shell Between the filling insulation cotton.There is a sample inside the studio shelf, used to place a variety of test items, the studio wall surrounded by mica heater.Gate seal with silicone rubber seal, the door is equipped with a door The vacuum chamber of the electric vacuum oven is controlled by the electromagnetic valve, and the electrical box is on the left side or the lower part of the cabinet. The front panel of the electrical box is equipped with vacuum gauge, temperature control instrument and control switch, Electrical box with electrical components.
Vacuum oven can be used as an ordinary electric box?
Can not be used as an ordinary thermostat, because not safe.Electrical drying oven at the bottom of the hole with fresh air to open the hole, the top of the studio has a ventilation adjustment port, the gas can be heated from the natural gas discharge adjustment chamber work, work The chamber is an unsealed vessel and therefore subject to a very small amount of gas pressure differential.The chamber of an electro-thermal vacuum oven has a very good airtightness due to its negative atmospheric pressure, and if it is heated in a vacuum- , The expansion of the working chamber gas may be due to break through the observation window toughened glass or containers and explosion.
Vacuum drying oven first vacuum heating and then heating reasons:
1, if the first heating and then vacuum the program operation, the heated air pumped out by the vacuum when the heat will inevitably be brought to the vacuum pump up, resulting in vacuum pump temperature rise is too high, it may reduce the efficiency of the vacuum pump.
2, the heated gas is guided vacuum gauge, vacuum gauge will have a temperature rise.If the temperature rise exceeds the vacuum gauge specified temperature range, it may cause the vacuum gauge to show the value of the error. Correct use It should be vacuum and then heating temperature to be reached after the rated temperature, if found to reduce the vacuum and then add the appropriate pumping about this to extend the service life of the device is beneficial.
3, the workpiece into the vacuum box vacuum is to remove the workpiece material can be removed in the gas composition.If the first heating of the workpiece, the gas will heat when the expansion of the vacuum box sealing is very good, inflated gas generated by This is a potential hazard, which can be avoided by operating the vacuum heating and heating program.
