ZJ ZJP Series Roots Vacuum Pump
OverviewThe series ZJP roots vacuum pump is with overflow valve.
Roots vacuum pump (referred to as roots pump for short) is a non-internal compression type rotary positive displacement pump, which achieves suction and exhaust by 2 8-shape rotors rotating in the pump shell. Its principle is similar with roots blower. As it works within the low pressure range, the free paths of the gas molecules are long, and the resistance is strong for gas to pass through small gaps, thus, it is able to obtain a higher compression ratio, and can be used as a booster vacuum pump; But it can not directly exhaust the gas into the atmosphere alone, and it shall be connected with a fore vacuum pump in series, and exhaust the pumped gas into the atmosphere through the fore vacuum pump.
Features
1. There is a certain gas between the rotor and pump chamber, and between rotors. They do not contact with each other, and do not need oil lubrication.
2. Rotor has a good geometric symmetry, and can improve the rotary speed so as to produce a compact large pumping rate pump.
3.Pump works with small vibration and large capacity, and the capacity utilization factor is around 0.5.
4. In the pump chamber, there is no compression as the mechanical vacuum pump does, so it does not require an exhaust valve. For this reason, it can be used to pump the condensable vapors.
5. It starts fast, and can achieve the ultimate vacuum in a short period. It has low power and low maintenance cost for operation.
6. Roots pump owns a high pumping rate in a wide range of pressures (1000PA ~ 1PA). It is able to quickly exhaust the gases which are suddenly released of gas, and cover the shortage of low pumping rate of the diffusion pump and oil sealed mechanical pump under the pressure of (1000PA ~ 1PA). As a result, it is most suitable used as a booster pump.
Applications
ZJ series roots vacuum pump is a kind of rotary positive displacement pump, which must be used with a fore pump. It has a higher pumping rate in a wider pressure range, and not sensitive to the pumped gases which contain dust or water vapor. Therefore, it is widely used in the metallurgy, chemical industry, food, electronic coating and other industries.

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.
