A centrifugal pump is a device that is used in sewage and water supply systems. Basically, such devices are used in public utilities. Due to the peculiarities of their design, they can pump a large amount of liquid of different viscosities.
The presented apparatus can be of several types, and the design of the device of each specific type is slightly different. However, the principle of operation of the pump is the only one for everyone. The injection and suction of the liquid occurs with the help of centrifugal force, which appears due to the rotation of the wheel with blades located in the body of the device. Water comes out of the machine much faster than it enters.
The centrifugal pump can be either single-stage or cantilever. As for its location in space, it can be installed both vertically and horizontally. The devices can be used at low, medium or high pressure. The liquid from the pump is discharged from one side or from both sides. With regard to the method of draining water fromapparatus, it can be scapular or spiral. Depending on where the device will be used, it is normal, high-speed and low-speed.
The centrifugal pump can be used in sewers, fire systems, and pump alkali, oil or chemicals. You can install the device on the surface or immerse it to a certain depth.
Mandatory for the presented unit is the flow part, which consists of a branch, a motive and an impeller. The last element is usually fixed at the end of the rotating shaft. The wheel transfers fluid energy from the engine. At the same time, it consists of a slave and a master disk. Between them are the shoulder blades, which have a certain one-sided bend.
The centrifugal pump ensures the movement of water from the impeller to the discharge pipe. If the device has a multi-stage structure, then the liquid is transferred from one pair of discs to the next. The operation and arrangement of the single-stage instrument is very simple.
When choosing centrifugal pumps for water, you need to pay attention to the speed of rotation of the wheel, as well as the size of the gap between the discs and the body of the device. The pressure under which water will flow from the pump depends on these parameters.
It should be noted that single-stage devices have a low level of maximum pressure. The largest number of impellers in a multi-stage device is 5 pieces. Naturally,The centrifugal water pump must be properly operated so that it has maximum performance. You should also take into account the pressure of the network in which the device will operate.
If you need a powerful pump that will work in a fairly large network, then you need to pay attention to those devices that have a high impeller speed.
The most common are cantilever centrifugal pumps. They have the most simple device and do an excellent job.
