The difference between submersible pumps and general centrifugal pumps
Thread Content
What is the difference between a submersible pump and a general centrifugal pump? When should I use a submersible pump?
A submersible pump is actually a centrifugal pump. There is not much difference. The submersible pump must be completely placed in the water and use water as a lubricant.
The electrode is special and seems to have an IP68 rating. Other structures are not much different from ordinary vertical pumps.
The submersible pump is a branch type of centrifugal water pump. Its characteristic is that the pump and motor are directly connected and coaxial. The motor is immersed in the liquid, and the protection level is relatively high.
Is there a submersible pump that is not a centrifugal pump? For example, a positive displacement submersible pump...
Submersible pumps are centrifugal pumps, which generally require the pump to be buried under the water, and submersible pumps also distinguish between water pumps and sewage pumps, etc.
When ordinary centrifugal pumps cannot suction, use a submersible pump or a self-priming pump.
this. . . . . . . . . . .
A submersible pump is a type of centrifugal pump. It is a pump used underwater. The inlet is at the bottom and the motor is on top. Generally, it does not run continuously.
The principles are different: the principle of a submersible pump is similar to that of an electric fan, while a centrifugal pump uses centrifugal force to throw water out. Of course, the shape is also different: the submersible pump is generally approximately cylindrical, and the centrifugal pump is approximately spiral. In terms of usage, the submersible pump submerses the pump body underwater, so the submersible pump has no suction. The centrifugal pump has a certain suction. From the working principle, the submersible pump also belongs to the centrifugal pump. The submersible pump is divided from the purpose. Because its structure does not have a centralized suction port and needs to be cooled in the water, the suction lift cannot be used.
Submersible pumps cannot evacuate, but centrifugal pumps do.
1. Centrifugal pumps include submersible pumps. Submersible pumps are only in the form of centrifugal pumps.； Second, because the impeller of a submersible pump is buried in the water, there is no need to add water to the pump body or evacuate it. Finished answering.
To add to the point, a submersible pump can transport liquid when it is immersed in liquid. A centrifugal pump sucks in and pushes out liquid through the centrifugal force generated by the rotation of the impeller. Therefore, this centrifugal force depends on the suction lift of the pump. The suction lift requires the height of the pump and the liquid level, the diameter of the inlet pipe, and the connection of the inlet pipe must be tight to prevent cavitation. :)
Submersible pumps cannot be used underwater centrifugal pumps:lol
The submersible pump is also a centrifugal pump type. Its characteristic is that the pump and the motor are directly connected and coaxial. The motor is immersed in the liquid, and the protection level is relatively high. General pumps use air cooling, while submersible pumps use water cooling.
The biggest difference is that the submersible pump is underwater and the ordinary centrifugal pump is on the water.
A submersible pump is a type of centrifugal pump that can work underwater.
Submersible pumps are also centrifugal pump types, and submersible pumps are easy to use temporarily! The weight is also lighter:victory:
Because the submersible pump is directly immersed under the liquid surface, the lift is not high. The impeller usually uses an open impeller. The other main difference is that the motor protection method is different. Generally speaking, the submersible pump is a type of centrifugal pump.
There is really no way to compare the difference between the two. Submersible pumps are distinguished by the working environment of the pump, while centrifugal pumps are classified by the delivery type of the pump. To make a distinction, we must first clearly define the concept. The definition of submersible pumps can include centrifugal pumps. As long as they meet the definition, they can be called submersible pumps. If the centrifugal pump is made waterproof and water-cooled, it is the most common submersible pump on the market. Nowadays, submersible pumps are basically referred to as common defaults.
