1、Parameter range of 2BW5 series vacuum complete set
2BW5 series vacuum complete sets are equipped with high-quality Kenflo water ring vacuum pumps. According to different vacuum requirements, 2BE1 series and CBF series water ring vacuum pumps can be configured.
When 2BE1 series water ring vacuum pump is configured, the effective working area is inlet pressure: 33mbar ~ 1013mbar (absolute pressure), and Kenflo patented p-type atmospheric ejector can be configured to extend the working area to 8mbar ~ 1013mbar (absolute pressure).

When CBF series water ring vacuum pump is configured, the effective working area is 200 mbar ~ 1013 mbar absolute pressure. Compared with 2BE1 series, it has higher efficiency in 200 mbar ~ 1013 mbar area and remarkable energy saving effect.

2、Working principle of water ring vacuum pump
The pump body is filled with an appropriate amount of water as the working fluid. When the impeller rotates clockwise in the direction indicated in the figure, the water is thrown around by the impeller. Due to the centrifugal force, the water forms a closed ring of approximately equal thickness that depends on the shape of the pump chamber. The inner surface of the upper part of the water ring is just tangent to the impeller hub, and the inner surface of the lower part of the water ring is just in contact with the tip of the blade (in fact, the blade has a certain insertion depth in the water ring). At this time, a crescent shaped space is formed between the impeller hub and the water ring, and this space is divided into several small cavities with the same number of blades by the impeller. If the upper 0 ° of the impeller is taken as the starting point, then the volume of the small chamber changes from small to large when the impeller rotates 180 °, and it is connected with the suction port on the end face. At this time, the gas is sucked in. When the suction ends, the small chamber is isolated from the suction port; When the impeller continues to rotate, the small cavity changes from large to small, so that the gas is compressed; When the small cavity communicates with the exhaust port, the gas is discharged from the pump.
To sum up, the water ring pump realizes suction, compression and exhaust by changing the volume of the pump chamber, so it belongs to the variable volume vacuum pump.
Compared with other types of mechanical vacuum pumps, water ring pumps have the following advantages:
The utility model has the advantages of simple structure, low manufacturing accuracy and easy processing.
The pump has a compact structure and a high number of revolutions. Generally, it can be directly connected with the motor without a reducer. Therefore, with a small structural size, a large exhaust volume can be obtained, and the floor area is also small.
The compressed gas is basically isothermal, that is, the temperature change during the process of compressed gas is very small.
Since there is no metal friction surface in the pump cavity, there is no need to lubricate the pump, and the wear is very small.
The seal between the rotating part and the fixed part can be directly completed by the water seal.
Uniform suction, stable and reliable operation, simple operation and convenient maintenance.
3、Composition and working process of Kenflo 2BW5 series vacuum complete set
The composition of 2BW5 series vacuum complete set mainly includes the following components:
(1) Water ring vacuum pump body;
(2) The prime mover, usually an electric motor, can also be a diesel engine, hydraulic motor, etc;
(3) The reducer shall be configured according to the different rotational speeds, sometimes it is required and sometimes it is not required. The reducer shall not be configured as far as possible to avoid adding a fault point;
(4) The steam water separation device is often equipped with our company's unique W-type gas water separation tank. The gas and water are completely separated. Special components are installed inside to absolutely prevent the gas from flowing out from the drain with the water flow. It is particularly important when pumping explosive and toxic gases;
(5) Heat exchanger, which can be configured with tube or plate heat exchanger;
(6) Water level indicator: Kenflo is usually equipped with a magnetic flap type liquid level indicator, which is accurate and obvious, and will not be blurred and unclear after long use;
(7) Various instruments;
(8) Internal connecting pipeline of the unit;
(9) Internal control valve of the unit; When solenoid valve, electric valve and pneumatic valve are used, full automatic control can be realized.
(10) Various connecting accessories in the unit

4、External interface of 2BW5 series vacuum complete set
External interfaces of 2BW5 series complete chemical plant mainly include:
(1) Water interface: including the working fluid replenishment pipe interface, the general liquid discharge interface, the cooling water inlet and outlet of the heat exchanger, and the filler water supply interface if the filler seal is used. Kenflo is responsible for providing water interface dimension drawings and technical requirements to users and design institutes after the contract.
(2) Air interface: including air inlet and air outlet. If pneumatic valves are used, there are also pneumatic pipeline interfaces. Kenflo is responsible for providing the dimension drawing of gas interface to the user and the design institute after the contract.
(3) Electrical interface: the strong current part is mainly the wiring interface of the motor; If the electric automatic fluid replenishing device is used to realize automatic control, there is also a weak current interface. Kenflo is responsible for providing electrical interfaces to users and design institutes.
