Technical Field

[0002] A Roots vacuum pump, also known as a Roots pump, is a type of variable displacement vacuum pump containing two lobe-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, preventing them from contacting each other. By combining and modifying Roots vacuum pumps with different functions, a vacuum unit can be formed. These units are widely used in industries such as petroleum, chemical, metallurgy, and textiles. During operation, the high-speed rotation of a Roots vacuum pump generates a large amount of heat. If this heat is not cooled, it can damage internal parts, reducing the pump's lifespan. Therefore, Roots pump units are typically cooled by external cooling units.

The fluid in the cooling pipes may contain some impurities, which can adhere to the fluid as it passes through the Roots pump's inner cavity. This reduces the actual space inside the Roots pump and decreases the efficiency of heat exchange. Therefore, a Roots pump cooling pipe filtration structure is needed to filter the fluid entering the Roots pump's cooling pipes, thereby improving the cleanliness of the fluid entering the Roots pump's inner cavity and thus improving the cleanliness of the Roots pump's inner cavity and the efficiency of its cooling.
