What are the common types of pump truck accessories in daily life introduced by the foundry
Generally, there are: impeller, bearing, sealing equipment, sealing information, spindle, key, inducer, and other information. A water pump is a mechanical device that transports or pressurizes liquids. It transmits the mechanical energy or other external energy of the prime mover to the liquid to add liquid energy. It is mainly used to transport liquids including water, oil, acid-base liquid, emulsion, suspended lotion, liquid metal, etc. It can also transport liquids, gas mixtures and liquids containing suspended solids.
The technical parameters of the water pump function include flow rate, suction head, head, shaft power, water power, power, etc; According to different operating principles, it can be divided into types such as volumetric water pumps and vane pumps. Positive displacement pumps use changes in the volume of their operating rooms to transmit energy; Vane pumps use the interaction between reverse blades and water to transfer energy, and there are types of pumps, such as centrifugal pumps, axial flow pumps, and mixed flow pumps.
The cutting ring, also known as the wear-resistant ring, is also an important component of the concrete pump. It is shaped like a circular ring and is called the cutting ring due to the shear motion during operation. Its effect is to provide support and avoid premature damage to the main seal. The commonly used manufacturing materials now include: high chromium alloy cast iron, tungsten carbide, hard alloy, and alloy ceramics.
