hydraulic cylinder piston

The piston make the function of seal and guidance in the hydraulic cylinder,different material also has the same piston function.HC the professional hydraulic cylinder manufacturer,also the manufacturer of piston and piston rod.
 The hydraulic cylinder is an airtight vessel, can be bearing pressure, the piston be possible to depend on the oil pour into, skids through the seal in the cylinder,thus transforms the fluid strength into the straight line or the curvilinear motion. Piston rod make form of  the movement which produces the piston transmits on the functional element, the fluid strength through enters the airtight container which from the piston and the cylinder , this kind of movement is produces depending on the liquid change in volume. The cylinder piston makes the main function of seal and guidance. Through piston rod power transmission. Its diameter different may have the different transmission ratio. Piston's function withstands the gas pressure, and passes to the connecting rod obligation crankshaft rotation through the piston pin, the piston top or combustion chamber's constituent. The working condition piston in the high temperature, the high pressure, high speed, the insufficient lubrication under the condition works. The piston with the high temperature gas contact, the instantaneous temperature may reach above directly 2500K, therefore, the heating is serious, but radiates the condition to be very also bad, therefore the piston works time the temperature is very high, the crown reaches as high as 600~700K, and the temperature distribution is very non-uniform; The piston top withstanding gas pressure is very big, specially makes the merit traveling schedule pressure to be biggest, the gasoline engine reaches as high as 3~5MPa, the diesel engine reaches as high as 6~9MPa, this causes the piston to have the impact, and withstands the lateral pressure the function; Piston in cylinder make reciprocal motion by very high speed (8~12m/s), and the speed is changing unceasingly, this makes big force of inertia, causes the piston to receive the big additional load. The piston works under this kind of bad condition, will produce distorts and accelerates to wear, will also have the additional load and the thermal load, simultaneously will receive chemical attack of the fuel gas .
