JZB Roots vacuum pump
1. Construction features and working principle of the pump:
Model ZJ Mechanical Booster Pump, also known as a Roots pump, is a volumetric pump.
It employs a pair of rotors, identical and in 8-figure with certain clearance between them
in the pump housing, rotating at the same speed in opposite directions to perform
function of suction and discharge of gas. The 2 rotors are supported by rolling bearings
in the end covers of the pump, rotating at high speed and are kept at a
fixed relative position by a pair of timing gears. The end clearance between rotors and
end covers are fixed by adjustable metal shims between the bearing housings and the
end cover at the fixed end, which ensures one-direction expansion of the rotor when
temperature rises during its operation.
Four sets of inner seals (also known as piston ring) in the 2 end covers prevent lube oil
entering into the pump housing. The shaft seal at the front-end cover, also called as
framework oil seal or shaft seal, prevents leakage of air into the pump housing.
In order to reduce temperature of the pump, all models of pumps (expect the two
smallest models) are equipped with a gearbox cooler and front-end cover cooler.
Power is transmitted through a coupling or V-belt from the motor to the driving shaft of
the pump and then through synchronizing gears to the driven shaft

Can Roots Vacuum Pumps Be Used for Vacuum Impregnation in Manufacturing?
Yes, Roots vacuum pumps can be used for vacuum impregnation in manufacturing. Here’s a detailed explanation:
1. Vacuum Impregnation in Manufacturing: Vacuum impregnation is a process used in manufacturing to fill porous materials or components with a liquid or resin. It is commonly employed to enhance the properties of materials by improving their strength, sealing capability, or resistance to chemicals or corrosion. The process involves placing the porous material in a vacuum chamber and removing the air or gas trapped within its pores. Once a vacuum is established, a liquid or resin is introduced, and the vacuum is released, allowing the material to absorb the impregnating substance.
2. Role of Roots Vacuum Pumps: Roots vacuum pumps play a crucial role in the vacuum impregnation process by creating and maintaining the required vacuum conditions. Here’s how they contribute:
– Evacuation: Roots pumps are used to evacuate the impregnation chamber, removing the air and gas from within the pores of the porous material. By creating a vacuum, the trapped gases are extracted, creating a void space for the impregnating substance to penetrate.
– Pressure Control: Roots pumps help control the pressure within the impregnation chamber during different stages of the process. They can rapidly achieve and maintain the desired vacuum level, ensuring proper impregnation of the material and preventing the formation of air bubbles or voids.
– Gas Removal: Roots pumps effectively remove gases released from the impregnating substance during the impregnation process. As the liquid or resin fills the pores of the porous material, gases may be released due to the reaction or outgassing. The vacuum pump evacuates these gases, preventing their accumulation and ensuring complete impregnation.
3. Advantages of Roots Vacuum Pumps for Vacuum Impregnation:
– High Pumping Speed: Roots vacuum pumps have a high pumping speed, enabling rapid evacuation of the impregnation chamber. This reduces the overall impregnation cycle time, increasing manufacturing throughput and efficiency.
– Large Volume Handling: Roots pumps are capable of handling large volumes of gas, allowing them to evacuate chambers of different sizes effectively. This is advantageous when impregnating large or complex-shaped components that require a significant amount of impregnating substance.
– Continuous Operation: Roots pumps can operate continuously, maintaining the vacuum conditions required for impregnation throughout the process. This ensures consistent impregnation results and reduces the risk of incomplete impregnation or material defects.
– Compatibility with Impregnating Substances: Roots vacuum pumps are compatible with a wide range of impregnating substances, including resins, oils, solvents, and other liquids. They can handle different chemical compositions and provide a clean and efficient environment for the impregnation process.
4. Considerations for Vacuum Impregnation:
– Material Compatibility: It is essential to consider the compatibility of the porous material with the impregnating substance and the impregnation process itself. Some materials may require pre-treatment or surface preparation before impregnation. The choice of impregnating substance should also align with the material’s properties and intended application.
– Process Parameters: Vacuum impregnation involves controlling various process parameters, such as vacuum level, impregnation time, pressure release, and curing conditions. These parameters may vary depending on the material, impregnating substance, and desired impregnation results. Proper process optimization and control are crucial for achieving consistent and reliable impregnation outcomes.
– System Design: The design of the vacuum impregnation system should consider factors such as chamber size, gas flow rates, vacuum pump capacity, and pressure control mechanisms. Proper system design ensures efficient operation, reliable vacuum conditions, and effective impregnation of the porous material.
In summary, Roots vacuum pumps are well-suited for vacuum impregnation in manufacturing. Their high pumping speed, large volume handling capability, continuous operation, and compatibility with impregnating substances make them effective in creating and maintaining the required vacuum conditions for successful impregnation. By considering material compatibility, process parameters, and system design, Roots vacuum pumps contribute to the efficient and reliable impregnation of porous materials in various manufacturing applications.
