Product description

Commodity name: 2BE1S series new two-stage water ring vacuum pump
Commodity ID: 1172831801458708480

2BE1S two-stage water ring vacuum pump product introduction:
2BE1S series water ring vacuum pump is a two-stage single-acting water ring vacuum pump based on the 2BE1 series, which has obtained the national invention patent.
As the latest invention patented product, 2BE1S series products have the following unique advantages:
High vacuum: Two-stage compression design, the ultimate vacuum can reach 2kPaA (-0.099MPaG), while the single-stage water ring vacuum pump can only reach 3.3kPaA (-0.098MPaG).
High efficiency and energy saving: The working efficiency of the high vacuum section (5～20kPaA or -0.096～-0.081MPaG) is 35% to 40% higher than that of a single-stage water ring vacuum pump, and energy consumption is correspondingly reduced.
High standard configuration: stainless steel, duplex steel, titanium, Hastelloy and other materials; mechanical seals at both ends; standard anti-cavitation devices; precision castings; imported bearings, etc.

Two-stage and single-stage water ring vacuum pumps are designed and developed for different operating conditions. It can be seen from the above curve that the pumping speed of the single-stage water ring vacuum pump at a higher vacuum degree (less than 20kPa) is seriously attenuated, and it is even less than 30% of the maximum pumping speed at 5 to 10kPa. The efficiency is extremely low under this working condition. High power consumption. However, it shows the advantage of large pumping capacity in the rough vacuum state. The two-stage water ring vacuum pump can obtain a higher pumping speed in a higher vacuum range, or maintain a higher vacuum in a large pumping rate range. When working in a higher vacuum, the efficiency is 35% to 40% higher than that of a single-stage water ring pump, and energy consumption is correspondingly reduced. Therefore, the appropriate vacuum pump should be selected according to the conditions of use to reduce energy consumption and economic operation.
Typical application of 2BE1S two-stage water ring vacuum pump:
■ The vacuum evaporation and rectification process of the matching evaporator: when working between 6-10kPaA, the efficiency is increased by more than 30% compared with the single-stage pump.
■ Atmospheric and vacuum vacuum device at the top of the fine chemical tower: When working between 5 and 6kPaA, it runs efficiently without the need to configure an atmospheric ejector, reducing equipment investment.
■ Power plant steam turbine condenser vacuum device: when working between 5 and 12kPaA, it can maintain high pumping speed and stable operation, without the need to configure an atmospheric ejector, high efficiency and energy saving.
■ Used as the front pump of the Roots vacuum pump: it can reduce the exhaust pressure of the Roots vacuum pump and avoid the phenomenon of overload, heating and even jamming of the Roots vacuum pump.
