Vacuum pump unitManufacturer introductionVacuum pump unitApplication

Vacuum pump unitApplication One: Pharmaceutical and Chemical

Vacuum pump applications include medicine, cosmetics and cleaning products, soap and synthetic detergents, printing ink and its additives, adhesives, photosensitive materials, water treatment agents and polymer flocculants, paper additives, leather additives, mineral flotation agents, foundry chemicals, metal surface treatment agents.

Applicable products: vacuum unit, water ring vacuum pump series, slide valve vacuum pump series, reciprocating vacuum pump series.

Vacuum pump unitApplication two: vacuum coating, vacuum drying, surface treatment

The film layer prepared in vacuum includes plating crystalline metal, semiconductor, insulator and other simple substance or compound film. Although chemical vapor deposition also uses vacuum means such as reduced pressure, low pressure or plasma, in general, vacuum coating refers to the deposition of thin films by physical methods. Vacuum pump applications play a vital role in the coating industry, surface treatment and drying.

Applicable products: vacuum unit, Roots vacuum pump series, slide valve vacuum pump series, rotary vane vacuum pump series, etc.

Vacuum pump unitApplication three: vacuum smelting, brick, ceramic manufacturing

The use of vacuum pumps is reflected in vacuum technology. This is a very critical part of the metallurgy and brick ceramic industry. It can be used to prevent the metal from being oxidized due to high temperature during processing. The moisture and air inside the bricks and ceramics are removed by vacuum to ensure high quality.

Applicable products: slide valve vacuum pump series, rotary vane vacuum pump series, vacuum unit, water ring vacuum pump series.

Vacuum pump unitApplication four: food packaging, milking, beverage industry

Vacuum packaging technology originated in the 1940 s. In 1950, polyester and polyethylene plastic films were successfully used for vacuum packaging, and vacuum packaging has developed rapidly since then. Vacuum packaging is to extract all the air in the packaging container and seal it, maintain the bag in a highly reduced pressure state, and the air is less than the low oxygen effect, so that microorganisms have no living conditions to achieve the purpose of fresh fruit and no disease and rot.

Applicable products: water ring vacuum pump series, rotary vane vacuum pump series, oil-free vacuum pump series, vacuum unit.

Vacuum pump unitMaintenance:

1、Vacuum pump unitDo not use in cold environments.

2、Vacuum pump unitCan be properly preheated before use.

3. Add bearing lubricating oil into the bearing body, observe the oil level should be at the middle line of the oil mark, and replace or supplement the lubricating oil in time.

4. Close the gate valve, outlet pressure gauge and inlet vacuum gauge of the outlet pipeline.

5. Move the motor to see if the rotation direction of the motor is correct.

6, if foundVacuum pump unitIf there is abnormal noise, stop the machine immediately to check the cause.

7, as far as possible.Vacuum pump unitThe flow and head are controlled within the scope of the label to ensure that the vacuum pump runs at a higher efficiency point to obtain a greater energy saving effect.

8. Regularly adjust the packing gland to ensure that the leakage in the packing cavity is normal, and dripping is appropriate.

9. When the vacuum pump is not in use for a long time, the pump should be disassembled, dried, the rotating parts and joints should be coated with grease and installed, and properly kept.

10. Regularly check the wear of the shaft sleeve, and replace it in time when the wear is large.

11. When the vacuum pump is used in cold winter, after parking, unscrew the drain plug at the bottom of the pump body to release the medium to prevent freezing and cracking.

12. Stop using the vacuum pump, first close the gate valve and pressure gauge, and then stop the motor.

13. Change the lubricating oil after 100 hours of operation in the first month of the vacuum pump, and change the oil every 500 hours thereafter.

14. Turn on the motor. When the vacuum pump is running normally, open the outlet pressure gauge and the inlet vacuum pump, and gradually open the gate valve after displaying the appropriate pressure. Also check the motor load.
