Bearing and cylinder piston compressor

2018 - bearing and cylinder piston compressor 11 - 10 / leather xiaoqing: bearing roller bearing has two columns symmetric spherical roller type, mainly bear radial load, but also can carry axial load in either direction, but can't afford to pure axial load. This kind of bearing outer ring raceway is spherical shape, so the self-aligning performance is good, can compensate the alignment error, when axial stress bending or install different heart bearings can still be used normally, so vary with different bearing size series, generally allowed by the self-aligning Angle for 1 ~ 2. 5 degrees, this type of bearing load capacity is larger, besides can bear radial load bearing can withstand the axial load, two-way role has good shock resistance, typically spherical roller bearing is allowed to work speed is low. Suitable for overloading or work under vibration load. Bearing, bearing bush was part of the sliding bearing and shaft neck contact, shape in tegular, cylinder is very smooth, usually made from bronze, anti-friction alloy wear-resistant materials such as, used to connect the crankshaft and connecting rod. In the cylinder, cylinder piston compressor is the main part of the volume of compression, the piston is playing within the cylinder for reciprocating motion. According to the stress, displacement compressors and compressor structure design for conditions. To install the valve on cylinder and sealing packing and the cylinder cooling. Cylinders with special material wear-resistant cylinder liner, cylinder wall outside channel, channel wall to separate airway of suction valve and exhaust valve, cylinder respectively according to different classes with gray cast iron, nodular cast iron and forging steel parts, cylinder liner abrasion resistance material selection and then coating materials, internal grinding process on the surface, forming the piston movement of the mirror.
