A centrifugal pump is a device that is used in sewage and water supply systems. Such devices are mainly used in public utilities. Due to the features of their design, they can pump a large amount of fluid of different viscosity.
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 pumping and suction of the liquid occurs by
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 apparatus much faster than it enters.
A 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. Liquid from the pump is discharged on one side or both. As for the method of draining water from the apparatus, it can be scapular or spiral. Depending on where the device will be used, it can be normal, high-speed and slow-moving.
A centrifugal pump can be used in sewers, fire systems, as well as to pump alkali, oil or chemicals. The device can be installed on the surface or immersed to a certain depth.
Mandatory for the presented unit is the flow part, which consists of a branch, a drive and an impeller. The last element is usually mounted on the end of the rotating shaft. The wheel transfers fluid to the fluid from the engine. Moreover, it consists of a slave and a leading disk. Between them are the blades, which have a certain one-sided bending.
A centrifugal pump provides 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 disks to the next. The operation and design of a single-stage device are very simple.
When choosing centrifugal pumps for water, you need to pay attention to the speed of rotation of the wheel, as well as to the amount of clearance between the disks and the casing of the device. The pressure at which water will flow out of 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,
a centrifugal
water pump must be properly operated so that it has maximum performance. You should also consider 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 speed of rotation of the impeller.
The most common are cantilever centrifugal pumps. They have the simplest device possible and do an excellent job.
