Roots vacuum pump manufacturer

The core technology of Roots vacuum pump lies in the excellent machining and clearance control of the rotor.The rotor adopts a symmetrical geometric design,and the Roots vacuum pump manufacturer achieves gas compression through high-speed rotation.During manufacturing,it is necessary to ensure that the gap between the rotor and the pump chamber,as well as between the rotors,is controlled within the range of 0.10-0.25mm to avoid direct contact friction.This process relies on high-precision CNC machine tools to complete,while ensuring the high strength and corrosion resistance of the material.
1、Processing and assembly of key components

As the core component of Roots vacuum pump manufacturer,its surface is a complex curved cylindrical surface,which is difficult to process and needs to be completed through multi axis linkage processing equipment.The matching accuracy of gears and bearings directly affects the stability of the pump.During assembly,it is necessary to ensure that the tooth clearance of the transmission gear is smaller than the smaller clearance between the rotors to prevent collisions during operation.In addition,the pump body adopts a split structure design,which facilitates maintenance and replacement of vulnerable parts such as sealing rings.

2、Sealing and cooling system integration
The Roots vacuum pump adopts oil-free sealing technology and reduces gas leakage through a labyrinth sealing structure.The cooling system of Roots vacuum pump manufacturer is equipped with dense heat dissipation fins or external cooling water pipes at the exhaust port,effectively reducing the heat generated by the compressed gas of the rotor and ensuring the long-term stable operation of the pump under high pressure difference.Some models are also equipped with a bypass overflow valve,which automatically opens the protection device when the exhaust pressure exceeds the standard.
3、Quality inspection and performance testing
Multi stage testing is required before leaving the factory,including pressure range verification,vibration detection,pumping speed calibration,etc.Adopting a dual pressure gauge monitoring system to ensure the discharge of pipeline residues during the cleaning phase.At the same time,monitoring the motor load through current can prevent the risk of overload.
4、Process adaptation on the application side
In the material conveying scenario,the Roots vacuum pump needs to be linked with the feeding device,dust removal device,etc.The workflow is divided into four stages:the feeding valve opens to fill the material→the gas valve starts to achieve fluidization→the discharge valve opens for conveying→the pressure returns to zero and the pipeline is cleaned.The system achieves automated control through level gauges and pressure sensors to meet the requirements of continuous powder transportation.
The Roots vacuum pump manufacturer stipulates that the lubricating oil needs to be replaced every 100 hours of operation,and the pump should be regularly cleaned of scale and checked for bearing wear.After use in cold winter,it is necessary to empty the medium to prevent freezing and cracking,and observe the lubrication status through an oil gauge on a daily basis.The overhaul cycle is one year,with replacement of gears,seals,and detection of rotor corrosion.
