2BV electric industrial vacuum pump

The vacuum pump of vacuum conveyor has two kinds of electric and pneumatic, among which there are two kinds of electric roots vacuum pump and liquid ring vacuum pump.

First, describe the electric liquid ring vacuum pump:

What we commonly use is liquid ring pump, among them 2BV series is most commonly used.

Using vacuum pumps advantages and disadvantages

1. The electric pump can be conveniently placed in the place without compressed air

2. Easy maintenance.

3. Capacity is guaranteed.

Disadvantages:

1. Arrange vacuum pipes

2. There is a certain amount of noise pollution

Liquid ring vacuum pump piping systems general requirements for equipment

Before the equipment pipeline, the first to check whether there is metal debris and other sundries in the pipeline. When the equipment pipeline, do not let the liquid ring vacuum pump to bear the pipeline component, or it will affect the precision of the pump equipment. After the end of the pipeline system equipment, the pump should not be affected by any part of the azimuth, should be able to make the whole operation parts can still rotate briskly.

In order to reduce resistance, the piping system should be as short as possible and avoid bending, as far as possible to reduce the gate, valve and switch to increase resistance lost accessories. The piping system of the liquid ring vacuum pump does not interfere with other equipment.

For the suction pipe, in order to avoid forming an air sac, the connection with the pump shall have a skew of 1:100, that is, the suction pipe shall be slightly higher than the Central Line of the inlet and outlet of the pump. Assuming that the suction pipe system is not able to attack the degree of skew, perhaps with the suction pipe connection attached equipment is lower than the pump, then can be connected in the pipe to meet this requirement. Assuming that there is liquid in the inhaled gas, the equipment tee seems more necessary. The diameter of the suction line should not be smaller than the diameter of the pump inlet.

When inhaled gas contains a large amount of liquid or possibly corrosive substances, a buffer tank should be equipped so that the liquid or harmful substances will flow into the tank, not into the pump, to avoid increased power consumption and corrosion of the pump body.

The suction pipe of liquid ring vacuum pump should be installed with reverse check valve to prevent water or other liquid from being thrown towards the suction pipe when parking. The suction pipe of liquid ring vacuum pump should be installed with reverse check valve to prevent water or other liquid from being thrown towards the suction pipe when parking. The suction line should not be spread over steam lines or other hot areas, as this will raise the temperature of the inhaled gas and then decrease the volume and vacuum.

In order to use vacuum pumps usefully, the gas is discharged directly into the atmosphere, which can reduce the exhaust resistance. The inner diameter of the exhaust pipe shall be equal to that of part of the pipe at the pump outlet. The same should try to avoid the exhaust pipe bending.

Air water separator should be close to the liquid ring vacuum pump, so that the connection channel will be shorter, reducing the resistance lost. When the equipment pump and the separator joint access channel, do not make the pipe to the direction of the separator has an upward slope, or when the operation, the tube is prone to retain liquid, increase resistance and power consumption, attack vibration.

About the liquid ring constrictor, the valve regulating gas pressure should be installed in the exhaust pipe of the gas-water separator, and should not be placed in the exhaust pipe of the pump (that is, the connection between the pump and the separator), otherwise it will greatly increase the consumption of power, so that the supporting motor overload. The pressure gauge for measuring the gas pressure should be installed on the top cover of the gas and water separator, and should not be installed near the exhaust port of the pump, or the pressure measured is not the gas pressure after the separation to the tightening system, but the mixed pressure of gas and water on the exhaust pipe of the pump.
