roots type vacuum pump

What is a roots type vacuum pump?

• Roots vacuum pump is a high-performance vacuum equipment that uses the mutual meshing of Roots impellers (or double Roots impellers) to achieve the purpose of air suction and exhaust.
• The principle is as follows: when the Roots impeller rotates, the gas forms a vacuum between the impellers due to the small gap between the impellers.
• At the same time, the gas at the air inlet of the vacuum pump is compressed. After the rotation of the impeller, the gas is sequentially transported and gradually expanded to achieve the purpose of exhausting.
• Roots vacuum pumps are widely used in the semiconductor industry, chemical industry and other fields due to their advantages of being oil-free and pollution-free, with large suction capacity, simple structure and easy maintenance.

Roots type vacuum pump working principle

• The working principle of the Roots vacuum pump is to use a pair of blade-shaped rotors to synchronously and counter-rotate in the pump chamber, sucking the gas from the air inlet, compressing it and expelling it through the exhaust port to achieve the air extraction function. ‌
• The characteristic of this kind of pump is that there is a certain gap between the rotors and between the rotors and the inner wall of the pump casing, allowing high-speed operation.
• Roots vacuum pump is a kind of vacuum pump without internal compression. Usually the compression ratio is very low, so it needs to be used in conjunction with a backing pump to achieve efficient pumping.
• This kind of pump is widely used in the fields of petroleum, chemical industry, plastics, pesticides, steam turbine rotor dynamic balancing, aerospace space simulation and other fields. It is favored because of its fast start-up, low power consumption, low operation and maintenance costs and other characteristics. favor. ‌

What is the difference between Roots blower and vacuum pump?

• 1.Working principle
• Roots blower is a device that achieves gas flow through two intermeshing rotors. It mainly sucks gas from one air inlet through the rotating rotor, and then discharges it through the other air outlet. The vacuum pump removes gas by using some method to reduce the air pressure inside the closed container. There is a big difference in how the two work.
• 2.Use
• Roots blowers are generally used to pressurize and transport gas, increase gas density, increase gas flow rate, etc. Mainly used in various industrial fields, such as food processing, electronic equipment, chemical industry, etc. The vacuum pump is mainly used to remove the gas inside the container to create a vacuum environment. Common uses include manufacturing semiconductors, vacuum heat treatment, vacuum cooling, vacuum packaging, etc.
• 3.Performance
• Roots blowers excel in pumping speed, volumetric efficiency and differential pressure range, and are capable of continuous operation for long periods of time, delivering clean, oil-free gas, making them ideal for many industrial industries. The performance of vacuum pumps may vary depending on their design use and operating conditions.

Roots type vacuum pump manual

• Precautions for use
• 1.Usage environment: Please ensure that the Roots vacuum pump is installed in a dry, ventilated and dust-free environment, avoiding direct sunlight and high temperature.
• 2.Power supply requirements: Please check whether the power supply meets the requirements of the pump before use, and make sure it is well grounded to prevent electric shock.
• 3.Operating specifications: During operation, please follow the steps in the operation manual to avoid damage or safety accidents caused by improper operation.
• Routine maintenance:
• 1.Clean the pump body and exhaust pipe regularly to keep the interior clean and free of debris.
• 2.Regularly check the power cord and grounding conditions to ensure safety and reliability.
• 3.If any abnormality or failure is found, please stop the machine in time and contact professionals for repair.
• troubleshooting
• 1.Pump body heats up: It may be that the motor is overloaded or the heat dissipation is poor. It is recommended to check the power supply voltage and ventilation conditions.
• 2.The air pumping rate decreases: It may be due to rotor wear or air leakage in the air pumping pipe. It is recommended to check the rotor wear and repair the air leakage point.
• 3.Increased noise: It may be that the rotor is unbalanced or the bearings are worn. It is recommended to check the status of the bearings and make necessary replacements.
• Safety warning
• 1.Disassembly and repair by non-professionals is prohibited: Disassembly by non-professionals may cause damage to the pump body or safety accidents.
• 2.It is prohibited to use in flammable and explosive environments: Roots vacuum pumps should be kept away from flammable and explosive items to prevent danger.
• 3.It is prohibited to touch rotating parts when the pump is running: When the pump is running, rotating parts may cause injury, so please keep a safe distance.
• Maintenance suggestions
• 1.It is recommended to conduct an excellent inspection of the Roots vacuum pump every three months to ensure that all components are in good condition.
• 2.It is recommended to perform professional maintenance on the pump body at least once a year to extend the service life and improve performance.
