Water-ring pumps are produced for pumping notonly water, but also oils. Some models are widely used in the perfume area. There are also modifications that are in demand at dairies processing enterprises. The main parameters of the devices include engine power, fluid density, and also the threshold pressure.

Water-ring vacuum pump: operating principle

Principle of operation of a water-ring type pumpis built on the rotation of the plates. Due to this, a large pressure is created inside the device chamber. A stator is used to rotate the shaft. At the pumps, the union is fitted with a head. In order for the nozzle to be firmly fixed, there is a protective ring. The liquid enters the pump chamber through the inlet. After the run, it enters the channel. Finally, all liquid is pumped through the pipe.

Pump type NSU-3 / 0,35

For pumping oil is indicatedwater ring vacuum pump. The principle of the device is based on a gradual increase in pressure inside the camera. In total, the model has five plates. The drive shaft is installed with a diameter of 2.3 cm. In this case, the pushers are provided with a head. For pumping water model is ideal. The engine at this pump is set at 3.4 kW.

The bushing is located at the base of the shaft. The permissible liquid density is 4 lm. The maximum pressure of the device is 10 MPa. In order to monitor the operation of the pump, a pressure gauge is installed. The weight of this model is 55 kg. To buy the presented water-ring vacuum pump it is possible for 22 thousand rbl.

The device BBH 2-50M

For pumping a liquid of low densitysaid water ring pump. The principle of the model is based on increasing the pressure due to the rotation of the plates inside the chamber. A device with two pushers is produced. There are four plates in the body. The drive shaft is set to 3.2 cm. The nozzle outlet is 4.3 cm. The total length of the drive shaft is 22 cm.

The device can withstand the threshold pressure in 12MPa. The protective ring of the model is used with a seal. The inlet is small in diameter. The body in the presented pump is made entirely of cast iron. The permissible liquid density is 3 lm. Buy a water-pump BBH 2-50M can be for 24 thousand rubles.

Models for dairy products

For dairy products, water ring vacuumThe pump is sold for two cameras. For water pumping, the device is ideal. In this case, the plates are placed at an angle of 12 degrees. The drive shaft for models is provided with a barbell. The permissible level of liquid density is 5.5 lm.

The threshold pressure of the device is 15 MPa. In all, the models have one bar. Plates in this case are at an angle of 12 degrees. In total, the pumps have two pairs of pins. The retainers are made of steel. Buy for dairy products water pump can be for 18 thousand rubles.

Devices for fat-and-oil products

Pumps of this type are manufactured with motorshigh power. If we consider modifications to the three plates, then they use the drive shaft to 2.2 cm. In this case, the allowable density of the liquid is 5 lm. The threshold pressure of the devices is 10.2 MPa. Cameras in many models are designed for 4.5 liters.

The pumps of this typeare quite different. If we consider modifications to five plates, then they have a density of 14 lm. In this case, the threshold pressure parameter fluctuates around 22 MPa. Buy a quality water pump of this type can be for 35 thousand rubles.

Features of models for the production of confectionery

Pumps for the production of confectionerydiffer in the volume chambers. The pushers in the devices are behind the head. In this case, the plates are located at an angle of 15 degrees. The permissible level of substance density is 10 lm. Threshold pressure pumps are maintained at an average of 13 MPa. If we consider modifications to three plates, they are produced with short drive shafts. In this case, the supports are located at a small angle.

It is also important to note that the market is represented bymodifications with rods. Two protective rings are installed at the outlet nozzle. The principle of the device is based on the rotation of the shaft. The motors for this are used with a power of 3 kW. Still on the market are selling pumps for five plates. Their angle of inclination is not more than 13 degrees. The threshold pressure of devices of this type is kept at the level of 15 MPa. It is also important to note that the permissible density of matter fluctuates around 8 lm. It is worth this type of water-ring vacuum pump (market price) about 30 thousand rubles.

Pumps for fruits and vegetables

A water pump of this type is produced withreinforced shaft. In this case, the rod is mounted with a steel support. Many modifications of this type are made on two outlet nozzles. If we consider a pump on three plates, then it has a filter for drying. Many models of this type are equipped with plugs. The motor is mounted behind the rotor. Its power is no more than 5 kW. Performance in this case depends on the volume of the camera.

If we consider a water pump for fourplate, then it has a cranked drive. On average, the drive shaft is used at 2.2 cm. Thus, the pump capacity fluctuates around 300 cubic meters. meters per hour. It is also important to note that devices with three outlet nozzles are available. It is worth a pump of this type about 32 thousand rubles.

Pumps in the cosmetic sphere

A pump of this type can be produced in twoplate. In this case, the rotor is used with a diffuser. The average motor power is 4 kW. Due to this, the performance parameter is kept at the level of 200 cu. meters per hour. Many pumps have filters for drying. The camera has an average capacity of 4.5 liters. It is also important to note that models are equipped with pressure gauges.

Threshold pressure devices do not exceed 10.3MPa. The permissible density of matter is 8 lm. If we consider a pump with four plates, then it uses a motor for 6 kW. The threshold of pressure of devices is about 12 MPa. Buy a pump of this type can be priced from 35 thousand rubles.

Models for perfume production

A pump of this type is produced with one rod. The motors on the devices are installed, as a rule, of the collector type. If we consider a pump on three plates, then it has a diffuser. On average, the threshold pressure parameter does not exceed 20 MPa. It is also important to note that the performance depends on the size of the main camera. For models with three plates, it is set to 4 liters.

water-ring vacuum pump

If we consider a pump on five plates, thenIt uses a drive rotor. As a rule, the rod is installed in the back of the case. The motor for the models is used at 12 kW. On average, the threshold pressure does not exceed 5 MPa. It is also important to note that the allowable density level is about 25 lm. Still on the markets there are modifications to six plates.

The cameras they use are 3 liters. The outlet nozzles in the devices are located at the rear of the structure. Motors are most often used collector type. The power rating of the devices is 7 kW. The permissible pressure parameter fluctuates around 13.5 MPa. You can buy this type of pump for 24 thousand rubles.
