Is the suction medium corrosive? 2SK-6 (non-corrosive) or F2SK-6 (corrosive) water ring pump with 300 roots pump should be fine, only one water ring pump can not be guaranteed to be achieved in the system, I hope it will help you.

Your conditions are not enough, your 5t kettle, how much material do you have in it? How much water is there after the reaction? How long does it take to draw it? Is there any corrosion? With these to choose the type, a water ring pump must be enough, but the model is not easy to choose.

2SK-12 water ring pump. It should be fine.

Summary. The water ring pump relies on the change of the volume of the pump chamber to achieve suction, compression and exhaust, so it belongs to the variable volume vacuum pump.

The water ring pump relies on the change of the volume of the pump chamber to achieve suction, compression and exhaust, so it belongs to the variable volume vacuum pump.

When the pressure in the small cavity space is lower than the pressure in the pumped container, according to the principle of gas pressure balance, the pumped gas is continuously pumped into the small cavity, and it is in the suction process at this time.

Water Ring Vacuum

Pump) is a mechanical device used to produce vacuum or compressed gas. It works by using a liquid, usually water, to form a rotating liquid ring to compress gas. Here is a detailed explanation of the air compression process of a water ring vacuum pump:

The main components of a water ring vacuum pump include a cylindrical pump body, an impeller mounted eccentrically in the pump body, and a liquid ring. When the pump is running, the impeller rotates with the drive shaft.

Due to the eccentric installation of the impeller and the centrifugal force, the liquid (usually water) in the pump body is pushed against the pump body wall, forming a liquid ring. This liquid ring rotates with the impeller to form a continuous annular cavity.

As the impeller rotates, the volume of the cavity between the ring and the impeller changes periodically. In the process of impeller rotation, when the volume of the cavity increases, the gas in the pump body is sucked into the cavity from the air inlet; When the cavity volume decreases, the gas is compressed and discharged from the exhaust port.

Throughout the process, the liquid ring acts as a piston, periodically drawing air in and compressing it from the intake and then expelling it from the exhaust port. At the same time, the circulation of the liquid ring also takes away the heat generated during the compression process, so that the water ring vacuum pump has a better cooling effect.

After the gas compression is completed, it is discharged from the pump through the exhaust port. In some water ring vacuum pumps, there may also be a separator to separate the discharged gas from the liquid so that the liquid can be recycled**.

In summary, the air compression of a water ring vacuum pump is achieved by the change in the volume of the cavity between the liquid ring and the impeller. The liquid ring acts as a piston that periodically draws and compresses the gas and discharges it from the exhaust port.

The centrifugal force of the centrifugal liquid ring is used to suction the air and the reverse pressure is discharged.

Water ring vacuum pump (referred to as water ring pump) is a rough vacuum pump, which can obtain an ultimate vacuum of 2000 4000pa, and a series atmospheric ejector can reach 270 670pa. The water ring pump can also be used as a compressor, called the water ring compressor, which is a low-pressure compressor, and its pressure range is 1 2 105pa gauge pressure.

The non-condensable gas is pumped out, and a negative pressure is formed at the pumping equipment, which is conducive to the circulation of working fluids.

The function of the water ring vacuum pump is to use the negative pressure conditions formed by itself to extract non-condensable, insoluble in water and non-particulate gases under the condition that the previous level of equipment is forming and operating normally.

Water ring vacuum pumps are used in various fields such as: chemical, pharmaceutical, papermaking, mining, food, etc., mostly used for purification, drying, etc.

Can be pumped, with a chemical composition of the gas!

The <> is connected to the pumping system by the air inlet on the right, the air outlet on the left drains and exhausts, and the thin water pipe in the middle is the water inlet pipe to provide water source for the water ring vacuum pump.

The circulating water is discharged from the exhaust port.

Yes, the water is exhausted from the exhaust port.

The structure is simple, the manufacturing accuracy is not high, and it is easy to process.

The structure is compact, the number of revolutions of the pump is high, and it can generally be directly connected with the motor without a deceleration device. Therefore, with a small structural size, a large exhaust volume can be obtained, and the floor space is also small.

Compressed gases are basically isothermal, i.e., the temperature of the compressed gas process changes very little.

Since there are no metal friction surfaces in the pump chamber, there is no need to lubricate the pump and there is very little wear. The sealing between the rotating and fastening parts can be done directly by the water seal.

The suction is uniform, the work is stable and reliable, the operation is simple, and the maintenance is convenient.

Water ring vacuum pump disadvantages:

The efficiency is low, generally around 30%, and the better one can reach 50%.

The vacuum level is low, not only because of the structural limitations, but more importantly by the saturation vapor pressure of the working liquid. With water as the working fluid, the ultimate pressure can only reach 2000 4000pa. Oil is used as the working fluid, up to 130pa.

In short, because the gas compression in the water ring pump is isothermal, flammable and explosive gases can be pumped out. Since there is no exhaust valve and friction surface, dusty gases, condensable gases, and gas-water mixtures can be extracted. With these outstanding features, it is still widely used despite its low efficiency.

Water ring vacuum pump features:

Compact structure, reliable working balance and uniform flow, so it is mostly used to transport or pump flammable, explosive and corrosive gases in chemical production. The efficiency of the water ring vacuum pump is very low due to the large energy loss due to the impeller agitating the liquid.

In order to make the pump run safely and have a long life, it is necessary to pay attention to daily maintenance, and the following aspects should be paid attention to in maintenance

Shaft seals. Maintenance: --

Water ring vacuum pump.

To regularly check the water pressure and volume of the seal, always keep a small amount of clean water flowing along the shaft, regularly adjust the packing gland, check the packing and change the packing regularly. The water pressure of the shaft seal and the amount of water in the shaft seal should meet the above requirements (shaft seal inspection). Equipped with.

Mechanical seals. When the pump is not used for a long time, the mechanical seal part should be filled with N46 oil to prevent the mechanical seal parts from rusting and the failure of the internal rubber parts.

Adjustment of the impeller:

In order to ensure the efficient operation of the pump, it is necessary to adjust the gap between the impeller and the front guard plate in time, stop the pump first when adjusting the impeller clearance, loosen the bolt of the compression bearing assembly, adjust the nut on the bolt, make the bearing assembly move forward, and rotate the shaft by hand at the same time according to the rotation direction of the pump until the impeller rubs against the front guard plate, relax the nut just tightened in front of it for half a turn, and then tighten the nut in front of the adjustment bolt to move the bearing assembly back, and the gap between the impeller and the front guard plate is between at this time. After adjustment, it is necessary to re-check whether the impeller rotates normally and whether the bearing assembly hold-down bolts are tightened before starting again, and then start the pump.
