2BV6 Series Liquid Ring Vacuum Pump Product Features and Maintenance Points

The 2BV6 series liquid ring vacuum pumps are popular in many industrial scenarios thanks to their outstanding and practical features.

From a design perspective, it adopts a tightly coupled design, which greatly simplifies the installation process and saves users a lot of installation space. This feature is undoubtedly very attractive to factories and workshops with limited space but require efficient vacuum pumps, allowing them to rationally arrange and operate efficiently in limited space.

In terms of sealing, the standard seals are all John Crane mechanical seals. As a well-known brand in the field of sealing, John Crane's products are known for their excellent sealing performance and reliability. The use of this high-quality seal can effectively prevent the leakage of working fluid in the pump, avoid equipment failure and production accidents caused by leakage, and also reduce the waste of working fluid and reduce operating costs.

Cavitation protection is a highlight of the 2BV6 Series liquid ring vacuum pumps. This series is equipped with cavitation protection ports, which can easily damage the pump's seal when the pump is operating for a long time under conditions close to liquefied vacuum. At this time, the cavitation protection port will automatically open (or connect with the separator) to discharge the gas in time and get rid of the impact of cavitation, thereby protecting the seal of the pump, extending the service life of the pump, and reducing the frequency and cost of maintenance.

The choice of impeller and pump body materials also fully reflects the excellent performance of this series of pumps. The aluminum bronze impeller has high strength and good wear resistance, and its use can significantly improve the pump's anti-corrosion ability, ensuring stable performance during long-term operation. If the liquid flow part is made of stainless steel, the pump can be used under more stringent conditions, such as in conditions containing corrosive media, which can effectively resist corrosion and ensure the normal operation of the pump.

The unique outlet design is another subtlety of this range of pumps. It protects the pump from overpressure, and when the system pressure rises abnormally, the outlet design can be automatically adjusted, ensuring optimal performance at all times within the operating range, avoiding equipment damage and safety accidents caused by overpressure.

The selection of motors and bearings also provides a strong guarantee for the stable operation of the pump. The motors are all Y2 series products, with a protection level of lP54 or lP55 (normal lP44) and an insulation level of F, which can operate reliably in harsh industrial environments, effectively prevent dust and moisture from entering the motor, and have good insulation performance to ensure the safe use of the motor. The bearings are imported from NTN or NSK brands, which have the advantages of high precision, low noise, and long life, reducing vibration and wear during pump operation and improving the overall performance and reliability of the pump.

When it comes to maintenance, regular inspection of mechanical seals for wear is key. Mechanical seals are prone to wear and tear due to the high pressure and friction they are subjected to during pump operation. Once the wear is found to be serious, it should be replaced in time to ensure the sealing effect. At the same time, it is necessary to pay attention to the wear degree of the impeller, although the aluminum bronze impeller has good wear resistance, but it may still affect the performance of the pump after long-term use, and it needs to be repaired or replaced if necessary.

For stainless steel components, it is necessary to regularly check their anti-corrosion status and clean the surface of dirt and impurities to prevent corrosion. In addition, regularly check the operating parameters of the motor, such as temperature, current, etc., to ensure that the motor is in good working condition; Lubricate the bearings regularly to reduce wear and extend their service life. Through scientific and reasonable maintenance, the performance advantages of 2BV6 series liquid ring vacuum pumps can be fully utilized and greater value can be created for enterprises.
