Roots vacuum pump
Hongguang series Roots vacuum pump Is a positive displacement pump, also known as mechanical booster pump, is one of the main equipment to obtain medium and high vacuum. It is another working mode of Roots blower. It uses two rotors to rotate synchronously in the pump shell to complete the process of suction and exhaust.
Roots vacuum pump The main advantages of this method are higher pumping speed and higher limit vacuum at lower inlet pressure. Since the operating parts of the pump (such as rotor and end cover) are not in contact, the pump has stable performance and long service life. Low maintenance cost
2. Scope of application:
It is widely used in vacuum smelting, vacuum welding, vacuum casting, vacuum coating, vacuum drying, vacuum dynamics experiment, chemical pharmacy, electric vacuum equipment manufacturing and other industries.
In view of the chemical, pharmaceutical and other industries, great steam degassing capacity is required. The seal structure of Roots vacuum pump cavity and bearing cavity has been improved, which greatly reduces the emulsification of bearing cavity and gear cavity oil. Therefore, roots vacuum pump is more suitable to use water ring vacuum pump to pump a large amount of water vapor and solvent.
3、 Main advantages
The working pressure is transferred to the high vacuum range. According to experience, it can be said that the root vacuum pump can be increased by 10 times to reach the limit pressure pump system. In some cases, this will not require the use of ultra-high vacuum pumps. Due to the non-contact rotation of the impeller, Roots vacuum pump The pump speed is doubled. Therefore, a relatively small pump can achieve a higher pump speed. Only with roots vacuum pump can the pumping speed exceed 1000 m3 / h (589 CFM). When choosing the right auxiliary pump (diameter), a small auxiliary pump can be used to deliver a large amount of gas. Compared with the single circuit pump at the same pumping speed, the energy consumption of the pump system is much less.
The use of Roots vacuum pump vacuum technology has brought about further specialization and improvement: through the integrated bypass (pressure balance pipeline), it is also possible to utilize the high pressure and initial large gas stage of Roots vacuum pump. This reduces the lowering time of the pump, especially during cyclic operation. The seal in contact with the atmosphere is not easy to wear. This can prevent leakage and failure caused by oil leakage. It usually exceeds 20000 hours of service life.
Tolerance and mass balance are combined with lubricated bearings and gears for high speed operation and the use of frequency converters. Therefore, a higher pumping speed can be achieved in the process, and the pumping speed can be reduced when the process stops or the batch is changed. This can reduce energy consumption, extend service life and reduce reliability. The conversion from vertical flow to horizontal flow is easy to achieve and can be installed in the installation position of the pump.
Therefore, the pump can be more closely adapted to the operating conditions of the system. Complex accessories (exhaust filters, separators, etc.) are not required; the lubricant effect in the side housing is very small, so the service life will not be reduced. The pump is prevented from being supported in the vacuum chamber by counter flow oil. An effective air cooler can minimize operating costs. No cooling water is required.
Roots vacuum pump provides directional airflow through the maximum static pressure, making it the best choice for local cooling and airflow through the pipeline. Alternatively, their high suction can be used to hold objects, or their directional airflow can be used to move objects.
Conclusion: the selection of Roots vacuum pump depends on volume flow, pressure, material type, space limitation and efficiency. Fan efficiency varies by design and type. Fans are divided into centrifugal flow and axial flow. In the centrifugal flow, the direction of the air flow into and out of the fan remains unchanged.
