Self-suction pump meaning
Now there are a variety of micro-pumps, micro-circulation pumps, micro-pumps, high-pressure miniature pumps, liquid sampling pumps, small pumps, self-priming pumps, DC pumps, diaphragm pumps, whether self-priming function, mainly see the following two points Self-absorption means: the pump suction pipe is the case of air, the use of negative pressure formed by the pump at atmospheric pressure will be lower than the water pressure on the pump up, and then discharged from the pump drain. This process does not require additional diversion guide. Pumps with this capability are called self-priming pumps. Some centrifugal or rotary vane pumps must be added to the pump chamber to form a closed environment before the pumps can operate in order to create negative pressure for water absorption purposes. For example, manual pumps used in rural areas. Pumps that do not have self-priming capabilities require a lot of hassle before each suction.
Suction level, with the pump power, flow, structure, etc. are related, but generally miniature pump self-priming suction is not easy to do higher, for example, a kind of micro-pump self-priming suction stroke can be achieved even higher The

Metals, alloys and composite powders commonly used in thermal spray hardfacing technology and coating service. These unique powders are instantly heated by thermal spraying (welding) methods such as high temperature flame or explosive flame, and are sprayed and deposited on the cold or hot workpiece surface with high-speed heat flow in a molten or semi-melted state to form a surface Reinforcing layer, in order to improve the wear resistance, corrosion resistance, heat resistance, oxidation resistance or repair of external dimensions of the workpiece surface. XTC produces WC, CrC, Oxide Ceramic, Boride Powder, Metal Alloy Powder, Pure Metal and Spray Wire, etc. product. For HVOF/HVAF/plasma/Flame spray coating and applications. Meet the wear and corrosion resistance requirements of different surfaces.
WC, CrC oxide ceramic powder and boride products are excellent in wear resistance and high temperature corrosion resistance. Taking WC products as an example, the hardness can reach HV1300-1500, and the temperature of CrC products can reach 800 degrees Celsius.
Metal alloy powder, Pure Metal and Spray Wire products have more applications in glass mold, steel and machinery industries. And XTC products are now become more and more popular in Metal spray coating and thermal spray coating industry.
