The piston compressor is working against the cylinder, the piston valve and the working volume constituted by the cylinder reciprocating the changing to complete. If you do not consider the actual work piston compressor volume loss and energy loss (ie, the ideal work process), then the piston compressor crankshaft per revolution of the work accomplished, can be divided into the intake, compression and exhaust. When the hydraulic oil HD32 Caltex crankshaft rotates through a transmission link, then the piston reciprocates, the working volume of the cylinder wall, cylinder head and the piston top surface is composed of a periodic variation of the piston occurs at the beginning of the cylinder head movement, the working volume within the cylinder increases Caltex hydraulic oil, then, that the gas along the intake manifold, intake valves and pushed into the cylinder until the change to the maximum working volume up, the intake valve closed; reverse movement of the piston within the cylinder working volume reduced, the gas pressure increases, the pressure within the cylinder when the exhaust pressure up to and slightly above, the exhaust valve opens, exhaust gas cylinder until the piston is moved to the limit position is reached, the exhaust valve closed. When the reverse movement of the piston again, the above procedure is repeated. In short, the crankshaft rotation, reciprocating piston, have been achieved within the cylinder intake, compression and exhaust process Caltex hydraulic oil dealers, to complete a cycle of work. When the crankshaft is rotated by a drive rod, the piston will reciprocate, the working volume of the cylinder wall, cylinder head and piston top surface composed of a periodic change occurs. When the piston starts moving from the cylinder head of the working volume of the cylinder increases, time, i.e., along the gas inlet pipe into the cylinder and the intake valve open until the displacement is changed to the maximum until the intake valve close ; reverse movement of the piston within the cylinder working volume of the hydraulic fluid out the latest original Caltex gas pressure increases, the cylinder pressure when the exhaust pressure up to and slightly above, the exhaust valve opens, exhaust gas cylinder until the piston movement to the limit position is reached, the exhaust valve is closed. When the reverse movement of the piston again, the above procedure is repeated. In short, the rotation of the crankshaft, a reciprocating piston, have been achieved within the cylinder intake, compression, exhaust process, a complete working cycle. Caltex Polyurea Grease Caltex Polystar Synthetic light color, a special class of non-EP grease. Using ISO 460 synthetic base oils, polyurea thickener, special anti-corrosion additives and antioxidants carefully modulated, apply to ordinary grease oxidation occurs due to severe hardening temperature is very high industrial lubrication of ball and roller bearings. Continuous operation temperature range is -30 ° C ~ 180 ° C; short-term maximum temperature of 230 ° C. Caltex Caltex Polystar Polyurea Grease smooth RB, purple grease, using a variety of depths refined mineral base oil mixture, polyurea thickener, special anti-corrosion additives and antioxidants carefully modulated. Suitable for speeds up to 500,000 DN of ball and roller bearing lubrication under high temperature or there will be serious (salty) water pollution conditions of work. Recommended major manufacturers of this product are: integrity Electric (Reliance Electric), Bardo Electric (Baldor Electric), the American Automobile (US Motors), GE (General Electric), Westinghouse (Westinghouse) and Siemens (Siemens ). Continuous operation temperature range is -35 ° C ~ 175 ° C; short-term maximum temperature of 200 ° C. Heavy extreme pressure grease Caltex Caltex Ultra-Duty Grease quality, heavy extreme pressure (EP) greases, high viscosity mineral oil, a lithium thickener, special extreme pressure (EP) additives, antirust agents, antioxidants, and thickeners carefully modulated. High adhesion properties make it particularly suitable for operating in wet, muddy conditions or dust flying vehicles and industrial equipment. Red.
