Fire pump is to fire fighting truck what heart to is to body, playing an very important role. Huaqiu fire pump builds domestic leading brand via its professional technology. Its efficient and low-energy flow components benefit from the perfect hydraulic model. The compact and convenient structure is derived from the advanced design concept.The reliable and smooth operation is the crystallization of the advanced process equipment.

There are 100 FAQs for you to study water pump.

Questions 1 - 10:

1. What is pump?

The pump is a machine that converts the mechanical energy of the original motive into the pumping of liquid energy. 

1. What is power?

The work done in unit time is called power.

2. What is effective power?

In addition to the energy loss and consumption of the machine, the actual power of the liquid in the unit time is called effective power.

3. What is axial power?

The power of the motor to the pump shaft is called the shaft power.

 

5. Why is it that the power of the motor to the pump is always greater than the effective power of the pump?

1）In operation, the centrifugal pump has a part of the high-pressure liquid to flow back to the pump entrance, even leaking out of the pump, so that it must lose some of its energy.

 2） When the liquid flows through the impeller and the pump shell, the flow direction and velocity change, and the interaction between the fluid also consume some energy.

6. What is the total efficiency of the pump?

The ratio of effective power to shaft power is the total efficiency of pump.

7. What is the flow of the pump? What is the symbol?

Flow refers to the amount of liquid (volume or mass) that flows through a section of the pipe in a unit time. The flow of the pump is represented by "Q".

8.What is the pump lift? What is the symbol?

The lift refers to the increment of energy obtained by the fluid of the unit weight. The lift of the pump is represented by "H".

9.What are the main types of mechanical pumps?

1）Vane pump. Through the rotation of the pump shaft, the blades of various impellers are driven by centrifugal force or axial force, conveying the liquid to the pipe or container, such as centrifugal pump, vortex pump, mixed flow pump, axial flow pump.

2）Positive displacement pump. Pump cylinder volume is used to transport liquid pump, such as reciprocating pump, piston pump, gear pump, screw pump;

3）Other type pumps. Electromagnetic pump is used to transport liquid electrical conductors; A pump that uses fluid energy to transport liquid, such as Jet pump, air lift.

10.What is the general mechanical disassembly principle?

In general, it should be removed from the outside to inside, first up and then down, and the whole parts should be removed as integral as possible.
