Longgu Roots blower manufacturer specializes in LGSR-V Roots vacuum pumps, LGSR-VHB high-pressure Roots vacuum pumps, Roots vacuum pump units, Roots two-stage vacuum pumps, which are insensitive to small amounts of water vapor and dust contained in the extracted gas. They have a high extraction rate in the pressure range of 100-1 Pa and can quickly discharge suddenly released gas, with high cost-effectiveness.

Product Introduction

The Longgu LGSR-VHB high-pressure Roots vacuum pump is a variable volume vacuum pump equipped with two blade shaped rotors that rotate synchronously in opposite directions. There are small gaps between the rotors and between the rotors and the inner wall of the pump casing, but they do not touch each other. The Longgu LGSR-VHB Roots vacuum pump has a wide range of applications, including petroleum, chemical, plastic, pesticide, metallurgy, textile, sewage treatment and many other industries.

working principle

The LGSR-VHB series high-pressure Roots vacuum pump is a vacuum pump without internal compression. Its working principle is similar to that of a Roots blower, mainly relying on the synchronous and reverse rotation of a pair of blade shaped rotors in the pump chamber to move gas and achieve vacuum pumping. During operation, due to the continuous rotation of the rotor, the pumped gas is sucked into the space between the rotor and the pump casing through the inlet, and then discharged through the exhaust port. Due to the fully enclosed state of the v0 space after inhalation, there is no compression or expansion of gas in the pump chamber. When the top of the rotor rotates past the edge of the exhaust port and the v0 space is connected to the exhaust side, due to the high gas pressure on the exhaust side, some gas rushes back into the v0 space, causing a sudden increase in gas pressure. The rotor continues to rotate, and the gas is expelled from the pump. The Roots pump has two 8-shaped rotors installed perpendicular to each other on a pair of parallel shafts inside the pump chamber, and is synchronously rotated in opposite directions by a pair of gear belts with a transmission ratio of 1. There is a certain gap between the rotors and the inner wall of the pump casing, which can achieve high-speed operation.
