How to maintenance roots vacuum pump

Roots vacuum pump (referred to as the Roots pump) is a rotary positive displacement pumps. It is evolved from the Roots blower. Depending on the scope of work Roots vacuum pump, is divided into vertical atmospheric low Roots vacuum pump; a Roots vacuum pump (also called mechanical booster) and high vacuum multi-stage Roots pump vacuum equipment. Now I will introduce how to correct for the Roots pump maintenance?

Belt drive and gear reducer drive this pump has two forms: low rpm, high efficiency, small size, flow rate, power consumption is small, self-absorption ability, not cited oil, easy to use and other characteristics can be widely used. transportation of oil and petroleum products (gasoline pump interchangeable copper leaf) and plant transport all kinds of oils and liquids such as crude oil, paint, oil, glass, plastic, oil acid, toothpaste and light alkaline (soap processing) liquids; food processing can transport a variety of liquids such as milk, yeast, starch syrup, etc. handling all kinds of trucks and oil tankers and other high speed, high efficiency, easy to use, the work can be reversing.

1. Always check the oil level position shall be adjusted to conform to requirements of non-compliance when the pump is running to the Roots, the oil level to mark the center of the oil prevail.

2, drain intervals according to the actual conditions of use and the ability to meet performance requirements, etc. considered at the discretion of the user. Most of the new Roots vacuum pump, pumping gas when in addition to a clean, dry, oil change is recommended once in about 100 hours of work. Until the oil after you do not see a black metal powder can later be extended drain intervals.

3, always check the oil, the discovery of oil deterioration should be replaced with new oil, ensuring the Roots pump is working properly.

4. In general, the Roots pump after 2000 hours of work should be carried out maintenance, inspection Jue rubber seals degree of aging, check the exhaust valve piece is cracking, cleaning deposits on the valve and the exhaust valve seat dirt. Cleaning the entire Roots pump chamber parts, such as the rotor, rotary vane, springs and other general cleaning with gasoline, and drying. after rubber parts can be cleaned with a dry cloth. cleaning assembly should be gently accidentally touch injuries.

5, bearing the body to join the bearing lubrication oil, observe the oil level should be the subject of the centerline of the oil, lubricating oil should be replaced or supplemented.

6. Check the Roots pump tubing and junction without loosening. Rotate the Roots pump, take a look at the vacuum roots blower is flexible.

7, should be re-assembled after the test run, are generally required to empty running two hours and the second oil change, because cleaning the Roots pump would have a certain amount of volatile matter, to be operating normally, and then put to work.

8, start the motor, when the metallizing roots pump functioning, open export and import Roots pump pressure gauge, depending on their shows after appropriate pressure, and gradually open the valve, and check the motor load conditions.

9, try to control within the roots rotary vane pump flow and head on the label of the range to ensure Roots pumps operate at maximum efficiency point, in order to obtain maximum energy savings.

10. To stop using the high vacuum roots pump, turn off the valve, pressure gauge, and then stop the motor.

11. vacuum booster pump during operation, the bearing temperature must not exceed the ambient temperature is 35C, the maximum temperature should not exceed 80C.

12. Roots pump in the first month of work by 100 hours to replace oil after every 500 hours, change the oil once ..

13, regularly adjust the packing gland, packing indoor drip ensure normal (with a drip out appropriate).

14 regularly check the wear sleeve, wear should be replaced after larger.

15. Roots pump long-term disabled, the need to pump all apart, dry water, and the junction of the rotating parts coated with grease installed, for safekeeping.

16. Roots vacuum pump during the winter season, parking, the need to unscrew the lower pump drain plug media will put the net. To prevent cracking.
