ABOUT PRODUCT
Features of Screw Rack:
The screw one belongs to rotated compressor whose remained volume is smaller than the reciprocated one,it has simple structure,high energy efficiency ratio,large discharge capacity,low vibration;In contrast to the reciprocated compressor,it has no expansion procedure for remained volume,no air inlet resistance resulted from air inlet valve plate,which brings high energy efficiency ratio on account of its high volume efficiency;It is also fitted with sliding valve energy regulation structure,multiple energy regulation and stepless energy regulation can be achieved easily;Â
Low Temperature Screw Rack Adopting Water-cooled Condenser And Oil Cooler
Water cooling owns high heat-exchanging coefficient,small heat-transfer space,which reduced the whole space and cost;
It is equipped with air exhausting pressure regulation valve for ensuring low condensing pressure and regular running of unit in winter;
It is also fitted with oil temperature mixing valve, which guaranteed stability of oil return temperature and lubrication,cooling,sealing of compressor; makes the volumetric efficiency more stable and the system runs more steady.

Bearing rings: Dimension tolerance, geometric tolerances, and surface quality of bearing` s working surface will influent the operating noise. Naimei Bearing adopts precision CNC machining to dimension precision, geometric tolerances, design drawing, mold making, grinding, cleaning, assembly, testing, every link of strict checks, so as to ensure all our products are tested by our strict criteria.
Balls: The balls evenly with by the cage, often make rolling movement between 2 rings. The shape, size and number will directly influent bearing`s load tolerance and operating capability. We use high precision, small vibration steel ball. It`s surface must be strengthened, no bumps scratches, lacerations, pitting and notch.
Cage: Enclose and move with all or part of the balls. It also be used to insulate the balls, guide the balls` movement and to improve lubrication performance inside the bearing., etc. Naimei Bearing`s cage is commonly made of cold rolling carbon steel. But in the corrosiveness environment, nonparallel or high-speed situation, stainless steel, engineering plastics cagecan be decided on request.
Seal: Naimei Bearing adopts different kind of seal material to meet the requirement of their operating in high temperature and being compatible with grease. Acrylonitrile-butadiene rubber is our standard material. but in high temperature environment ,often adopt fluorocarbons, silicone , PTFE shield.
