Pump knowledge training materials â‘ 

What is a pump? A: It is usually referred to as a pump that lifts liquid, transports liquid or increases pressure on the liquid, ie, changes the mechanical energy of the prime mover into liquid energy. Pump classification? A: The purpose of the pump varies, according to the principle of action can be divided into three categories: 1, the volume pump 2, vane pump 3, the other types of pump displacement pump works? Example? A: The use of cyclical changes in the volume of work to transport liquid. For example: piston pump, piston pump, diaphragm pump, gear pump, skateboard pump, screw pump and so on. Vane pump works? Example? A: Liquids are transported using the liquid interactions of the blades. For example: centrifugal pump, mixed flow pump, axial flow pump, whirlpool pump and so on. Centrifugal pump works? A: Centrifugal pump relies on the role of the impeller on the liquid to the prime mover mechanical energy transfer to the liquid, due to the role of centrifugal pump liquid from the impeller inlet to the outlet of the process, its speed and pressure can be increased by the impeller discharge of liquid through Out of the room most of the speed can be converted into pressure and then sent along the discharge pipe. At this time, the impeller inlet side due to the discharge of liquid to form a vacuum or low pressure, the liquid sucked in the pool liquid level pressure (atmospheric pressure), that is pressed into the impeller inlet. As a result, the rotating impeller continuously inhales and discharges the liquid.

Flexible Flap Disc

Flexible Flap Disc is suitable for polishing of stainless steel, metal, metallurgy, automobile, wood, marble and other industries. It is especially suitable for the processing of stainless steel and can replace the resin-shaped grinding wheel. It has strong elasticity, high tensile and bending strength, good self-sharpening, high grinding rate, and low noise. It is suitable for welding seams in the box. Polishing of the edges.

According to the type of abrasive particles: ceramic alumina VS zirconium corundum VS alumina

According to the type of abrasive selected, the flap disc can be divided into three types: ceramic alumina, zirconium corundum and alumina.

Because ceramic alumina itself has many crystals, it has good self-sharpening, relatively neat edges, good heat dissipation, and long service life. Therefore, ceramic alumina louvers are mainly used for the grinding of stainless steel, aluminum and other hard metals.

Zirconium corundum itself is a polycrystalline crystal, with fast cutting speed, good self-sharpening, and strong resistance to high pressure and high temperature. Therefore, zirconium corundum louver blades have strong cutting ability and long service life.

Alumina: single crystal, the cutting ability begins to decline at the beginning of grinding, and the abrasive grains are not easy to break, so the alumina flap disc is suitable for the processing of common metals.
