What are the basic working principles of centrifugal pumps?

What are the basic working principles of centrifugal pumps?

There are many types of centrifugal pumps, but the working principle is the same, and the structure is similar. The main working parts are the rotating impeller and the fixed pump casing (Figure 2-1). Impeller is a centrifugal pump to do work directly on the liquid components, which has a number of backward curved blades, generally 4 to 8 pieces. When the centrifugal pump works, the impeller is driven by the motor for high-speed rotation (1000 ~ 3000r/min), forcing the liquid between the blades to rotate. At the same time, due to the centrifugal force, the liquid from the center of the impeller to the outer edge of the radial movement. The liquid obtains energy during the movement of the impeller and leaves the outer edge of the impeller at high speed into the volute pump housing. In the volute, due to the gradual expansion of the flow channel and deceleration, but also part of the kinetic energy into static pressure energy, to reach a higher pressure, then along the tangential flow into the pressure pipe.

Basic knowledge of water pump 1

Basic knowledge of water pump 1

Water pump is to transport liquid or liquid pressurized machinery. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the liquid energy. It is mainly used to transport liquids including water, oil, acid and alkali, emulsion, suspension emulsion and liquid metal.

Five Common Valve Types

Five Common Valve Types

The gate valve is used as a cut-off medium. When it is fully opened, the whole flow is straight through. At this time, the pressure of the medium is small and the loss is small. Gate valves are usually suitable for conditions that do not require frequent opening and closing, and that keep the gate fully open or fully closed. Not suitable for use as a regulator, throttling. For high-speed flow of the medium, the gate in the local open condition, can cause the vibration of the valve, and vibration, and may damage the sealing surface of the gate and valve seat, and throttling, will make the gate subjected to media erosion. From the structural form, the main difference is the form of the sealing element. According to the form of sealing components, often the gate valve is divided into several different types, such as: wedge gate valve, parallel gate valve, parallel double gate valve, wedge double gate gate, etc. Commonly used in the form of wedge gate valve and parallel gate valve.

What is the function and principle of the trap

What is the function and principle of the trap

The basic function of the steam trap is to discharge the condensed water, air and carbon dioxide gas in the steam system, and to prevent the leakage of steam automatically. The variety of traps is very much, there are different performance. Here to share the trap working principle is as follows:
