1)The Feature of industrial 100ton air cooled screw type water chiller
a..Excellent performance
The main body is equipped with globally advanced semi-hermetic screw compressor,intergrating the motor,without worrying about shaft seal leakage.
The single or number of compressors are provided with startup-shutdown cycle control program so as to uniformly load parts and extend their service life.
Multiple refrigrating cicuits are provided for the sigle or number of comprssors ,and when on cicuits is under maintenance,other cirucits are albe to run nomally as mutual standby.
Unload deprssurized start is provided for the compressors to prevent the impact on the power grid

b.Complete safety protections
Pressure protection:High and low-pressure protecting devices
Motor protection:Voltage-loss protection, phase-loss protection,inverse phase protection and over-heat protection.
Anti-freezing protiction:The unit will stop running in case of excessively low cooling water temperature
Safety valve protection:when the refrigerant pressure exceeds a certain value, the safety valve will be turned on automatically
Above device  protections ensure the safe and reliable running of the unit
c.Easy assembly 
The unit enjoys compact structure,covers small area,saves machine room space;it almost not vibrates due to the provision of foundation anti-vibrating measure.
Upon delivery of the units R22 refrigerant and lubricationg oil have been filed into it, then it's only necessary to connect the evaporator water pipe during assembliy,saving time and cost.

Laser Cladding Powder

Nickel Based Laser Cladding Powder

Ni base alloy powder is mainly made of NiCrBSi or NiBSi. Ni-based self-fluxing powder has good wettability, corrosion resistance and high temperature self-lubricating effect, and is used in components with heat resistance, corrosion resistance and thermal fatigue resistance. In general Ni35,Ni45,Ni60 etc can be used for laser cladding, the No means hardness of powder. Inconel 625 and 718 has good corrosion property under higher temperature, also widely used for laser cladding process.


Cobalt based Laser Cladding Powder

Cobalt-based alloy powder is the cemented carbide resistant to various types of wear and corrosion as well as high temperature oxidation. That is, the so-called cobalt-chromium-tungsten (molybdenum) alloy or Stellite alloy cobalt-based alloy is mainly composed of cobalt, containing a considerable amount of nickel, chromium, tungsten and a small amount of molybdenum, niobium, tantalum, titanium, Alloying elements such as lanthanum, and occasionally a class of alloys containing iron.

Co-based self-fluxing alloys have good high temperature performance and wear resistance and corrosion resistance, and are used in petrochemical power, metallurgy and other industrial fields where they are wear-resistant, corrosion-resistant and high-temperature resistant.

Laser Cladding


Iron based Laser Cladding Powder

The work pieces required for laser cladding and manufacturing in the actual industry are mainly carbon steel and cast steel. The Fe-based alloy is close to the base material in composition and has good wettability. The advantage of Fe base powder is lower cost and good wear resistant of cladding layer. As a result, it`s the most widely used for laser cladding process. It is suitable for parts that require local wear resistance and are easily deformed.

Laser Cladding Work Part



WC blended Laser Cladding Powder

Tungsten carbide blended with Ni alloy powder is the best choice for wear resistant work piece. This unique process can bring excellent wear, corrosion and high temperature resistant. Our blend powder can achieve different portion of WC from 35% to 60% without crack under suitable cladding parameter.
