ROOT PUMP

A rotary positive displacement pump is the Roots vacuum pump (referred to as the Roots pump). It is derived from the blower of the Roots. A Roots vacuum pump (also called mechanical booster) and high vacuum multi-stage Roots pump vacuum equipment are divided into vertical atmospheric low Roots vacuum pump; depending on the scope of work Roots vacuum pump.

This pump has two types of belt drive and gear reducer drive: low rpm, high performance, small size, flow rate, small power consumption, ability to self-absorb, non-cited oil, simple to use and other features can be widely used.

All kinds of oils and liquids such as crude oil, paint, oil, glass, plastic, oil acid, toothpaste and light alkaline (soap manufacturing) liquids can be transported by the transport of oil and petroleum products (gasoline pump interchangeable copper leaf) and plants; food processing can transport a range of liquids such as milk, yeast, starch syrup, etc.

Often check the oil level location shall be changed to conform to requirements of non-compliance when the pump is running to the Roots, the oil level to mark the centre of the oil prevail.
Drain cycles, considered at the user's discretion, according to the actual conditions of usage and the ability to meet performance criteria, etc. Most of the current Roots vacuum pump, pumping gas when it is recommended once in around 100 hours of work in addition to a clean dry, oil shift. Until the oil does not reveal a black metal powder, drain intervals can be expanded later.
Always check the oil, replace the discovery of oil oxidation with new oil, ensure that the Roots pump works correctly.
In general, maintenance should be carried out on the Roots pump after 2000 hours of operation, checking the degree of ageing of the Jue rubber seals, checking the cracking of the exhaust valve portion, cleaning deposits on the valve and dirt of the exhaust valve seat. It is possible to clean the rubber parts with a dry cloth. Cleaning assembly may brush wounds gently accidentally.
To bear the body to join the lubricating oil bearing, to observe the oil level should be the focus of the oil centerline, to substitute or complement the lubricating oil.
Without loosening, inspect the Roots pump tubing and junction. Rotate the roots pump, take a look at the flexible vacuum roots blower.
After the test run, should be reassembled, two hours of running and the second oil change are usually expected to be empty, so cleaning the Roots pump will have a certain amount of volatile matter, to be working normally, and then put to work.
Start the engine when operating the metallizing roots pump, open export and import Roots pump pressure gauge, depending on their display after sufficient pressure, and open the valve gradually, and check the conditions of engine load.
Try to monitor the flow of the rotary vane pump within the roots and the head on the range label to ensure that the root pumps work at the highest efficiency point in order to achieve maximum energy savings.
Turn off the valve, the pressure gauge, and then stop the motor to stop using the high vacuum root pump.
During operation, the vacuum booster pump must not exceed the ambient temperature of 35C, the maximum temperature should not exceed 80C, the bearing temperature must not exceed 35C.
Roots pump 100 hours after every 500 hours in the first month of work to replace oil, change the oil once.
Change the packing gland regularly, packing indoor drip ensures natural dripping (with a drip out appropriate).
Check the wear sleeve periodically, wear after larger should be replaced. A fifteen. Long-term disabled roots pump, the need to pump everything apart, dry water, and the junction of the built grease coated rotating sections, for safekeeping.
The net will be mounted by the Roots vacuum pump during the winter season, parking, the need to unscrew the lower pump drain plug media. Preventing cracking.
