Function of centrifugal pump press out chamber

37. What is the function of centrifugal pump? How many forms of DP?

Answer: the function of screw pump press out chamber is to correctly guide the liquid with minimum loss

The next stage impeller may be led to the outlet pipe, and part of the kinetic energy is converted into pressure energy at the same time.

There are three common types of diaphragm pump press out chamber:

(1) Spiral volute is used to collect liquid gear pump. Kinetic energy becomes pressure energy

It is carried out in the diffuser.

(2) Radial guide vane, which is fixed outside the impeller outlet

The role of.

(3) Ring type press out chamber, used on segmented multi-stage pump*

38. What is the texture color given by centrifugal spring leaves 7

Answer: the impeller of centrifugal pump is generally made of metal, which enters according to the liquid flow

It can be divided into single suction PR force and double suction impeller, which are mainly composed of blade and wheel

The two-part 6-wheel is used to fix the blade and fix the calling wheel on the pump shaft-l.

39. What is the function of centrifugal spring coupling 7

Answer: the function of centrifugal pump coupling is to connect the pump shaft with the prime mover shaft

Play a role in transmitting the energy of the prime mover, buffering axial and radial vibrations, and

Automatically adjust the operation of the prime mover and the slave machine.

40. How many LP couplers are used?

Answer: there are three commonly used couplings:

(1) Rigid coupling, suitable for small, low-speed words with little vibration

On each;

(2) Elastic coupling is suitable for high-speed equipment with variable load,

(3) Gear couplings are mostly used on low-speed heavy equipment.
