What is the choice of oil-free permanent magnet variable frequency vacuum pump? Advantages over traditional water ring vacuum pumps

Shengquan energy-saving vacuum pumps are more effective than traditional water ring vacuum pumps, mainly reflected in the following aspects:
Higher efficiency Advanced design and working principle: For example, dry screw vacuum pump, through the fine dynamic balance correction of the two screws running in the pump shell, there is a gap between the screws without friction, smooth operation, can efficiently extract air. Magnetic suspension centrifugal vacuum pump using magnetic bearing system to make the motor rotor stable suspension, drive the impeller to do work on the gas, eliminate friction loss, can achieve high efficiency and stable operation.
Strong ability to adapt to working conditions: Shengquan energy-saving vacuum pump can automatically adjust the operating state according to different working needs and working conditions to maintain high efficiency. For example, the claw-type dry oil-free vacuum pump adopts frequency conversion control, and the energy consumption is relatively constant at low vacuum. When the inlet vacuum is high, the energy consumption is significantly reduced, and it can maintain good performance in different vacuum interval. 3.
Higher vacuum degree: Shengquan energy-saving vacuum pumps can achieve higher vacuum degree. For example, a single pump of a dry screw vacuum pump can be directly pumped from atmospheric pressure to a vacuum degree of 1Pa (absolute pressure), while the ultimate vacuum degree of a water ring pump can usually only reach 2000Pa. To obtain a higher vacuum degree, it is necessary to connect with a multi-stage Roots vacuum pump or a multi-stage steam jet pump in series, which is not only complex in structure, but also prone to failure. 2.
Optimized power system with lower energy consumption: Shengquan energy-saving vacuum pump adopts high-efficiency and energy-saving motors and drive systems, which can effectively reduce power consumption. And its intelligent control system can precisely adjust the speed and power of the motor according to the actual pumping demand, avoiding unnecessary energy waste. Take Xinlei maglev centrifugal vacuum pump as an example, compared with water ring vacuum pump, it can achieve 100% water-free, oil-free, no loss, and still maintain high-efficiency and stable operation in high-temperature corrosive and harsh environments, helping enterprises to save electricity bills significantly.
Reduce the energy consumption of auxiliary equipment: Some Shengquan energy-saving vacuum pumps do not need to rely on a large amount of circulating water to maintain their operation like water ring vacuum pumps, thus reducing the energy consumption of the circulating water system, including the energy consumption of the pump operation and the energy consumption of cooling equipment that may be required to maintain the water temperature stability. For example, the oil-free screw energy-saving vacuum pump of Mikitsu does not require water, which not only reduces the consumption of water resources and wastewater discharge, but also saves the energy consumption related to the complex water circulation system.
Better stability and reliability High durability of components: Shengquan energy-saving vacuum pumps usually use high-quality materials and advanced manufacturing processes, and the durability of key components is strong, not easy to wear and damage, and can operate stably for a long time. For example, the screw oil-free compression vacuum pump launched by German and Japanese companies uses internal hollow cooling screw, which can reduce rotor temperature and thermal deformation, prolong screw life, and reduce downtime caused by component damage.
Less affected by working conditions: When the traditional water ring vacuum pump runs for a long time, it is easily affected by factors such as rising water temperature and extracting solvents, resulting in a decrease in vacuum degree. However, Shengquan energy-saving vacuum pumps such as dry screw vacuum pumps are not affected by water temperature and extracting solvents, and operate stably for a long time2.
Better environmental performance No water or low water consumption: Many energy-saving vacuum pumps do not require a lot of water, avoiding water waste and wastewater discharge problems, and meeting environmental protection requirements, such as oil-free screw vacuum pumps and magnetic suspension centrifugal vacuum pumps, which are characterized by no water operation.
No oil pollution: Some energy-saving vacuum pumps operate in a dry mode, without the need for lubricating oil in the working chamber. They do not generate oil vapor to pollute the vacuum system and the pumped gas, and also avoid environmental problems caused by the handling and discharge of oil substances, such as dry screw vacuum pumps and claw dry oil-free vacuum pumps.
