DESCRIPTION
Roots Rotary Piston Pump System is made up with the Roots Vacuum Pump and Rotary Piston Vacuum Pump in series connection. Rotary Piston Vacuum Pump is used as the pre-vacuum pump and the backing vacuum pump of the Roots Vacuum Pump, while the Roots Vacuum Pump is the main vacuum pump. The selection of displacement ratio, between the Roots Vacuum Pump and the Rotary Piston Vacuum Pump, is mainly referred to the vacuum value of the vacuum system under long term running; when working in low vacuum, it is advised to select small displacement ratio(2:1 to 4:1); If working in medium or high vacuum, the bigger displacement ratio(4:1to10:1)should be preferred.
Â
Â
Â
Â
Â
ADVANTAGE
1.High vacuum, high exhausting efficiency in medium or high vacuum, wide working range, obvious energy-saving results.
2. Integrated rack, compact structure, small required space.
3. High automation, simple operation, easy maintenance, safe, reliable and durable running.
4. To customize a special pump system as per the specific needs of the end user.
Â
Â
APPLICATION
Widely used in vacuum coating, vacuum metallurgy, vacuum heat treatment, vacuum drying, vacuum impregnation, vacuum strainer, poly-silicon production, aerospace simulation and so on.

ZJ-300Mixed Powder
Tungsten carbide is a very hard and wear-resistant material, making it ideal for applications where high abrasion resistance is required. It is often mixed with other metals, such as nickel, cobalt, or chromium, to form a metal alloy powder. These metal alloys enhance the properties of the tungsten carbide and improve its compatibility with the base metal.
The tungsten carbide mix metal alloy powder is typically fed into the PTA welding torch, where it is melted and propelled onto the surface of the base metal using a high-energy plasma arc. The molten powder forms a hard, dense coating that bonds with the base metal, providing excellent wear resistance and protection.
The specific composition of the tungsten carbide mix metal alloy powder can vary depending on the application requirements. Different ratios of tungsten carbide and other metals can be used to achieve desired properties, such as hardness, toughness, and corrosion resistance.
Overall, tungsten carbide mix metal alloy powder is a versatile and effective material for PTA welding, offering superior wear resistance and protection for various industrial applications.
