Sudan hydraulic cylinder,retractable cylinder manufacturer,retractable cylinder(Sudan retractable cylinder,produced by Hebei Hengyu company)
retractable cylinder are widely used in Sudan,because of clever hydraulic energy conversion,simple structure and reliable operation,excellent temperature resistance.So our company has designed retractable cylinder for customers from Sudan.
1, the hydraulic machinery should be kept clean, in order to prevent dust and debris from falling into the oil, the tank should be sealed. 2, the oil in the tank should be replaced regularly according to the working condition. When changing the oil, the dirt and impurities accumulated at the bottom of the tank should be removed and the tank should be cleaned. 3, hydraulic oil, oil drums should be set in a clean and safe place to strengthen management. The oil drum, oil filter, oil funnel, oil pipe, etc. used should be kept clean. The oil drums for loading hydraulic oil must be cleaned in advance, and the oil drums should be dedicated and not mixed with other oil drums.
The piston rod of the retractable cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.
Piston retractable cylinder is widely used in hydraulic transmission. When the retractable cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the retractable cylinder, and uses the pressure difference of hydraulic oil on both sides of the piston to realize the reciprocating movement of the piston. If you want to speed up the forward speed of the piston, the return oil in the retractable cylinder can be controlled by the valve and directly input into the inlet pipe to participate in the work of the piston to achieve rapid movement of the piston, but the thrust of the piston is reduced much.
When the control pressure of the hydraulic system is too low, the retractable cylinder will appear wrong or no action, because the throttle resistance in the control pipeline may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is interfered with. At this time, check the control pressure source to ensure that the pressure is adjusted to the specified value of the system.
How to judge the failure of forklift hydraulic cylinder?
The common faults of the hydraulic cylinder of forklift truck are mainly crawling, insufficient thrust, working speed decline or even stop. Generally, crawling occurs at low speed. The main reason is that the air stored in the cylinder is not cleared. In addition, excessive or uneven mechanical friction can also cause crawling. Such as the piston and the piston rod different heart, the piston rod full length or local bending, the cylinder hole straightness is poor, the cylinder is drum shaped or has a large taper, the cylinder thin finish decline or produce hair, the cylinder installation accuracy is out of whack, the piston rod nuts at both ends of the screw too tight to make its concentricity is poor, the oil seal screw too tight friction is too large, will cause crawling.
For a cylinder with a piston diameter of 100mm and a system pressure of 10MPa, what is the thrust?
Thrust is 7850 kg. Piston area A= πR^2=7850 square mm =78.5 square cm 10MPa = 100kg/cm^2 "^2" is square F = A x P =78.5 x 100=7850 kg.
