2BE3 series large-size water ring vacuum pumps – the "all-rounder" and performance innovat

In modern industrial production, vacuum technology is the core link to ensure process stability and improve product quality. From pulp dewatering in the paper industry to material distillation in the chemical industry, from underground drainage in mining to condenser vacuum in power station operation, the performance of the vacuum pump directly determines the operating efficiency and reliability of the system. The 2BE3 series large-size water ring vacuum pump launched by us has become a benchmark product in the field of industrial vacuum with its innovative design of duplex progressive cavity pump structure and full working condition adaptability, solving the problems of high-load, long-cycle, and complex gas treatment for customers.

Core role: one pump and two effects, to meet the needs of multiple vacuums

Traditional water ring vacuum pumps often require multiple equipment to operate in parallel when coping with the needs of multiple working conditions, which not only occupies a large space, but also has high energy consumption and complex maintenance. The 2BE3 series uses intermediate wall separation technology to set up an isolation layer with a pressure resistance of less than 80kPa in the pump casing, dividing the pump chamber into two independent working areas, each of which can be connected to different vacuum systems to achieve "one pump for two purposes". For example, in chemical production, one side can handle process vacuum containing corrosive gas, and the other side can simultaneously vacuum equipment without corrosive gas, eliminating the need for additional backup pumps, significantly reducing equipment investment and operating costs.

The duplex progressive cavity pump construction of this series of pumps further enhances its adaptability. The screw rotor adopts variable pitch design, with a large pitch at the suction end to quickly capture gas and a reduced pitch at the exhaust end to compress gas, which reduces gas backflow and energy loss, so that the pump can maintain efficient operation in both rough vacuum (101-10kPa) and medium vacuum (10-1kPa). For example, in the underground drainage system of mines, the pump needs to continuously pump a mixture of water vapor and dust, and the 2BE3 series ensures stable operation under harsh working conditions for more than 8,000 hours without failure through a high-flow design (a single flow rate can reach 5000m³/h) and wear-resistant coated rotors, far exceeding the industry average.

Technical features: Triple breakthrough of energy saving, flexibility and durability

Diversified drive mode, saving space and energy consumption
The 2BE3 series supports multiple drive modes such as V-belt drive, direct synchronous motor connection, and gearbox speed increase, and customers can flexibly choose according to the space and power requirements of the site. For example, in the vacuum scenario of the power station condenser, the direct connection of the synchronous motor can eliminate the belt transmission loss and improve the motor efficiency to more than 95%; In the papermaking workshop with limited space, the speed increase of the gearbox can integrate four pumps into one motor drive, reducing the footprint by 60%, and at the same time using the waste heat of the motor to keep the pump body warm, reducing the energy consumption of starting in winter.

Upgraded materials and processes to extend service life

For the gas characteristics of different industries, the pump body material is available in various options such as carbon steel, stainless steel 304/316L, and duplex steel. For example, when treating hydrogen chloride gas in the chemical field, Hastelloy C-276 coated rotor is used, which can resist the erosion of highly corrosive media. In the mining scenario, the inside of the pump body is sprayed with a wear-resistant layer of tungsten carbide, and the wear rate of key components is still less than 0.05mm/year even if the sand-containing gas is pumped for a long time. In addition, dynamic sealing technology (such as mechanical seal lip seal combination) and air ballast valve design effectively prevent gas leakage and liquid backflow, ensuring long-term stable operation of equipment.

Intelligent control integration to achieve unattended operation and maintenance

It can be equipped with an optional frequency conversion speed control module and an Internet of Things monitoring system, which automatically adjusts the operating frequency of the pump to match the process requirements by monitoring the vacuum degree, temperature, vibration and other parameters in real time. For example, during the vacuum pumping process of a chemical reactor, when the vacuum level reaches the set value, the system automatically reduces the rotation speed to 30%, which not only maintains process stability, but also reduces energy consumption by more than 30%. At the same time, the fault warning function can predict bearing wear, seal leakage and other problems 72 hours in advance, and guide customers to spare parts in advance to avoid unplanned downtime.
