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 .

Double acting hydraulic cylinders China

HC- China hydraulic cylinder suppliers as one of the best China hydraulic cylinder sellers provide double acting hydraulic cylinders China. And hydraulic cylinder making is devoted ourselves to double acting cylinder China.

Double acting hydraulic cylinder is a very common hydraulic cylinder type which means both oil ports with oil entering and both direction controlled by oil pressure. When piston rod works, the force of pushing is bigger than pulling, and the piston rubs with the inside barrel thousands of times so if the seals is not good enough, leaking will happen after a time. And HC-China hydraulic cylinder supplier’s double acting hydraulic cylinder picks the best match for rod and bore, at the meantime as per customers’ requests.

HC hydraulic cylinder theory parameters:

Installment and revolution
*Box openning
In the reason of cylinder inside seal with chemical property rust-preventing agent,do not dismantle the entrance before assemble the plug. If dismantles the plug, must install immediately on organism, moreover puts the full oil in the cylinder.
* Rust prevention
The cylinder installs after organism, if piston in stretches out when in the situation lays aside, must reveal the part painting fat in the connecting rod.
* Speed
Generally specification cylinder, when the movement speed surpasses 2m/s, its service life will be influenced. Takes the stroke terminal by 0.3m/s the situation, in order to protect agency and the security, suggests the internal installment buffer gear. Moreover, when the cylinder stops, in order to protect the cylinder organization and the security, on the line must consider prevents the big impact of wallop. In order to increase cylinder's oil discharge quantity, the line designs should be pay special attention. When 0.5m/min idling, will affect the movement specially vibration, therefore, time idling, should carry on the discussion.
* Revolution
The revolution initial period, must clear out the air in the cylinder completely. The residual air's situation, adopts the low speed to revolve fully. If in cylinder residual air sudden crimp, as a result of the hydraulic fluid function, possible to cause the seal packing collar loss by burning. Moreover, in movement, if the cylinder interior has the negative pressure, that will have the possibility to occur as a result of the cavitation function exceptionally.
