The main water ring vacuum pump should be applied to coal mines (gas extraction), chemicals, pharmaceuticals, mining, paper, food, beer, building materials, plastics, metallurgy, electrical appliances and other industries. The structure is simple, the manufacturing precision is not high, and it is easy to process. Compact structure, high pump speed, generally can be directly connected with the motor, no need to reduce the device. Therefore, with a small structure size, a large displacement can be obtained, and the footprint is also small. The compressed gas is essentially isothermal, ie the process temperature of the compressed gas changes very little. Because there is no metal friction surface in the pump chamber, it is not necessary to lubricate the pump and the wear is small. The seal between the rotating part and the fixing part can be done directly by the water seal. Inhale evenly, stable and reliable work, simple operation, easy maintenance. There are many types of water-producing ring vacuum pumps, which can be divided into 2BA type water ring vacuum pumps, 2BV type water ring vacuum pumps, SK type water ring type vacuum pumps, and 2SK type water ring type according to the ultimate vacuum degree reached and the size of the pumping volume. Vacuum pumps, SZ-type water ring vacuum pump these major categories. Jiangyin Suyi Vacuum Equipment Co., Ltd. is a professional production of vacuum pumps and vacuum units of the backbone enterprises. Has many years of production experience, product quality and stability. The main products include rotary vane type 2BE1 series, 2BV series, 2X series, 2XZ series, XD single-stage rotary vane series, water ring vacuum pump and compressor, SZ series, SZB series, SK series, SK series, 2SK series and each A vacuum unit.
PTA Powder
Main application:Repair and strengthen workpiece surface, significantly
Welding method:PTA welding
Main equipment:PTA welding machine
Flame core temperature: about 10000℃
Technological characteristics:PTA has high temperature, concentrated energy, stable combustion, small heat affected zone, fast welding speed, high production efficiency, easy to obtain low dilution rate of surfacing layer, surfacing layer and workpiece matrix are metallurgical bonding,, bonding strength is high.
PTA welding technology is one of surface strengthening methods, which has high deposition rate, low dilution rate, and could be applied with many kinds of powder. The manufacturing craft of PTA powder is normally gas atomization, which reduces satellite of powder. We supply 4 main categories of PTA powder: Nickel-based alloy powder, Iron-based alloy powder, Cobalt-based alloy powder and Mixed Powder.
Nickel Based Alloy Powder possesses high temperature resistance and wear resistance, it is the most popular alloy powder applied by PTA welding both domestically and internationally. Coating hardness is within the range of HRC 30-60. It could be applied to various industries like agriculture, plastic, paper, marine and steel making where wear and corrosion protection needed. Some examples are plunger, moulds, pump leaf and screw.
Iron Based Alloy Powder is more widely used and a more economic choice. With high abrasive resistance, it is more commonly applied to mining tools, drilling tools and mixers of iron and steel making industry, coal industry, shaft, oil and energy industry.
Cobalt Based Alloy Powder is recommended for corrosion and oxidation resistance, with better hot hardness values than equivalent Nickel based alloy powder. It is widely applied to steel making industry, coal industry and mining industry.
Mixed powder mainly refers to NiCrBSi mixing with other hard-phase powder such as cast tungsten carbide and other cemented alloy powder, which allows the powder better hardness around HRC60 and excellent abrasion resistance.
Mixed powder is more often used for mining equipment for oil sands, lignite, oil drilling tools, excavator buckets, extrusion screws for plastic processing, grain and oil processing, etc.
