Vacuum dryers How

1, be placed in a vacuum drying oven of items within the box door, and close the release valve, open the vacuum valve, vacuum pump connected to the power started pumping, so that the vacuum box to-0.1MPa, close the vacuum valve, then turn off the power vacuum.

2, the vacuum oven  power switch to "on" Office, select the desired temperature setting inside the temperature began to rise, when the box temperature is close to the set temperature, heat indicator light suddenly suddenly put out, repeated many times generally accessible temperature state within 120min.

3, when the required temperature is low, the second set the method can be used, such as the required temperature 60 ℃, for the first time can be set to 50 ℃, the temperature overshoot and so began to fall, then the second set the 60 ℃. This can reduce or even eliminate the temperature overshoot phenomenon, as soon as possible into the constant temperature condition.

4, depending on the degree items damp, select a different drying time, such as the drying time is longer, the vacuum drop is required to restore the vacuum exhaust again, should open the power vacuum, and then open a vacuum valve.

5,  should be closed after the end of the power, open the release valve to relieve vacuum box, resort to remove the items out of the box door.

Note the vacuum drying oven

1, vacuum tank shell must be effectively grounded, in order to ensure safe use.

2, vacuum chamber without continuous pumping use, should first close the vacuum valve, then turn off the power vacuum, or vacuum pump oil to flow backward to the box.

3, tear out articles to be processed, such as dealing with flammable materials, must be cooled to below the ignition temperature before they can into the air to avoid oxidation caused by combustion.

4, non-essential, do not arbitrarily open the side door to avoid damage to electrical systems.

5, no explosion-proof vacuum box device, explosive materials shall not be placed in drying.

Six, the should be installed special air switch.

7, good electrical insulation, equipment enclosure must have reliable access protection or the protection of ground zero.

8, vacuum tank and vacuum pumps across the filter between the best to prevent the wet gas enters the vacuum pump.

9, electric vacuum oven can be used only under special guard to ensure that the equipment running.

10 out of items to be processed, such as when dealing with flammable materials, must be cooled to below the ignition temperature, the air can be placed, in order to avoid oxidation caused by combustion.

11, vacuum pump oil should be changed frequently.

12, no proof of this equipment,  devices, explosive materials shall not be placed in drying.

13, electric vacuum oven abnormal phenomenon should be timely inspection, maintenance, can not accurately determine if the failure to contact with the purchasing company’s technology.

14, such as long-term without the vacuum box should be painted in the plating neutral oil or petroleum jelly to prevent corrosion, and wear a plastic film Dust, anti in the dry room, avoid electrical parts damp affect use.
