The unique design ensures that the medium does not come into contact with oil during its flow inside the pump, completely eliminating the pollution of oil to the process and the environment at the source. It is especially suitable for industries with extremely high requirements for cleanliness, such as electronic chip manufacturing and pharmaceuticals.
It can achieve an extremely high vacuum degree, far exceeding that of water - ring pumps and reciprocating pumps. It can completely replace them and meet the demanding process requirements for vacuum environments, such as vacuum coating and vacuum drying.
A variety of models and specifications are provided, allowing for flexible selection according to different production scales and process requirements. The equipment operates with high efficiency and stability, has a low failure rate, and the maintenance operation is simple, reducing the equipment maintenance costs and downtime of enterprises.
Through the remote control system, operators can monitor the operating status of the equipment remotely and perform operations, reducing the number of on - site staff. This not only improves work efficiency but also reduces labor costs and further cuts down operating costs.
A well - known semiconductor manufacturing enterprise had extremely high requirements for the cleanliness and vacuum degree of the vacuum environment during the chip manufacturing process. The traditional vacuum pumps previously used could not meet its growing production needs. There were not only risks of oil pollution to the chips, but also the unstable vacuum degree affected the chip quality. After adopting the conventional dry screw vacuum pump, these problems were perfectly solved. Its oil - free flow - through characteristic ensured the cleanliness of the chip production environment, the high vacuum degree met the chip manufacturing process requirements, the high - efficiency and stable operation of the equipment improved production efficiency, and the remote control function also achieved unmanned operation in the workshop, greatly reducing labor costs and helping the enterprise enhance its product competitiveness.
It is used in links such as lithography, etching, and film coating during chip manufacturing to provide a high - vacuum and pollution - free environment.
In processes such as drug drying, concentration, crystallization, and sterile preparation production, it ensures the cleanliness and stability of the vacuum environment.
It is suitable for processes such as silicon wafer production and battery module packaging, ensuring the vacuum requirements during the production process.
In chemical reactions, distillation, drying, and other processes, it maintains stable vacuum conditions to promote the progress of reactions.
In addition to the main equipment of the conventional dry screw vacuum pump, it also includes supporting motors, cooling systems, nitrogen supply systems, control systems, etc. According to different application scenarios and process requirements, auxiliary equipment such as filters and buffer tanks may also be equipped.
Check whether the connections of all components of the equipment are firm, whether the supplies of lubricating oil, cooling water, nitrogen, etc. are normal, and whether the electrical system is safe and reliable.
First, turn on the cooling system to ensure the normal circulation of cooling water, and then start the motor to make the vacuum pump start running.
During the operation of the equipment, the pumping rate, vacuum degree, motor current, temperature, and other parameters are monitored in real - time through the remote control system or on - site instruments to ensure the normal operation of the equipment.
First, stop the motor, then turn off the cooling system and other auxiliary equipment, and finally carry out necessary equipment maintenance and upkeep.
According to the weight and size of the vacuum pump, a suitable concrete foundation is made to ensure that the foundation is flat and firm and can withstand the vibration and weight during the operation of the equipment.
Use lifting equipment to hoist the vacuum pump onto the foundation and adjust the position of the equipment to make its levelness meet the requirements.
Connect the intake pipeline, exhaust pipeline, cooling water pipeline, nitrogen pipeline, etc. according to the design requirements to ensure that the pipeline connections are tight and leak - free.
Connect the motor power cables, control lines, etc. of the vacuum pump to ensure that the electrical connections are correct and safe, and carry out necessary grounding protection.
After completing the equipment installation and connection, conduct commissioning and operation to check whether the equipment operates normally and whether all parameters meet the requirements.
When selecting a model, factors such as pumping rate, ultimate full pressure, special requirements of the application scenario, and budget need to be comprehensively considered. For example, semiconductor manufacturing has high requirements for vacuum degree and cleanliness, so models with low ultimate full pressure and oil - free flow - through can be selected; if large - scale chemical production requires rapid gas extraction, specifications with high pumping rates should be emphasized.
First, check whether there is leakage in the intake pipeline, which can be detected by methods such as applying soapy water; secondly, check whether the seals inside the vacuum pump are worn, and if so, replace them in a timely manner; in addition, check whether the motor speed is normal, as a decrease in motor speed caused by motor failure will also affect the vacuum degree.
Regularly check the quantity and quality of lubricating oil and replace the grease according to the specified time; check whether the cooling water pipeline is unobstructed and whether there is any water leakage; regularly clean the filter to prevent impurities from entering the pump body; check whether the connection parts of the equipment are loose to ensure the stable operation of the equipment.
By installing an intelligent control system, connect the vacuum pump to the remote control terminal and use network technology to achieve data transmission. Operators can monitor the operating parameters of the equipment in real - time through terminals such as computers or mobile phones and perform operations such as starting, stopping, and adjusting the speed.
Its oil - free and pollution - free characteristics themselves meet the cleanliness requirements of pharmaceutical production. In addition, the materials and surface treatment of the equipment should meet the standards of the pharmaceutical industry, and the equipment should be regularly cleaned and disinfected to ensure that it does not affect the quality of drugs.
The foundation should have sufficient strength and stability to withstand the vibration and weight generated during the operation of the equipment. The flatness error of the foundation should be controlled within the specified range to ensure the levelness of the equipment installation and avoid operating failures caused by equipment tilting.
Motor speed, gas temperature, gas composition, and pipeline resistance will all affect the pumping rate. When the motor speed decreases, the pumping rate will follow suit; if the gas temperature is too high, the gas volume will expand, reducing the pumping efficiency; if the gas contains impurities or viscous substances, it may block the internal channels of the pump body; excessive pipeline resistance will hinder gas flow and also reduce the pumping rate.
Compared with water - ring pumps and reciprocating pumps, the dry screw vacuum pump has a higher vacuum degree, is oil - free and pollution - free, and can meet higher - requirement processes; compared with other dry vacuum pumps, it has complete specifications, a wider application range, high - efficiency and stability, easy maintenance, and lower operating costs.
It is mainly applied in the silicon wafer crystal pulling process to maintain the vacuum state in a high - temperature environment and ensure the growth quality of silicon wafers; in the battery module packaging link, rapid gas extraction realizes vacuum packaging, improving the stability and service life of battery modules.
Although the initial purchase price may be relatively high, considering factors such as the improvement in production efficiency, reduction in maintenance costs, and long service life brought about by its high performance, in the long run, it has a higher cost - performance ratio and can save the overall operating costs for enterprises.
