(Malaysia stroke adjustable cylinder,produced by Hengyu Hydraulic Cylinder Factory）

stroke adjustable cylinder are widely used in Malaysia，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed stroke adjustable cylinder for customers from Malaysia.

Introduction to stroke adjustable cylinder:

Repair method of small range wear of oil stroke adjustable cylinder: 1. Use oxygen-acetylene flame to bake the scratched part (master the temperature, avoid surface annealing), bake the oil on the metal surface all the year round until no sparks splash; 2. The scratched part is treated with an Angle grinder, the grinding depth is more than 1 mm, and the groove is polished along the guide rail, preferably a dovetail groove. Scratch both ends of the drilling deeper, change the force situation; 3. Clean the surface with absorbent cotton dipped in acetone or anhydrous ethanol.

In the process of using the stroke adjustable cylinder, sometimes such a problem will occur, the stroke adjustable cylinder can not act immediately after the instruction of the stroke adjustable cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil stroke adjustable cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

When the stroke adjustable cylinder is installed, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the stroke adjustable cylinder head, earring (or middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent rigid interference and cause unnecessary damage.

stroke adjustable cylinder piston rod material selection and technical requirements: (I), because there is no special requirements, so use 45 steel as the piston rod material, the design of the piston rod only withstand pressure stress, so no modulation processing; (ii) The coaxial tolerance of the shaft journal and the outer circle of the mounting piston is not greater than 0.01mm, so as to ensure the coaxial degree of the outer circle of the piston rod and the outer circle of the piston, and avoid the stuck phenomenon of the piston and the stroke adjustable cylinder, the piston rod and the guide. The vertical tolerance between the end face of the mounting piston and the axis of the piston rod is not more than 0.04mm/100mm to ensure that the piston installation does not produce skew; (iii) The outer circle of the piston rod should pay attention to the roughness; (iv) Because it is operated under low load conditions, surface treatment is omitted.

Answers to some questions about stroke adjustable cylinder:

Cylinder pressure calculation formula
The pressure of the cylinder at work is determined by the load, and the pressure of the physical force is equal to the force divided by the area of action (that is, P=F/S). If you want to calculate the output force of the cylinder, you can calculate it according to the formula: Set the radius of the piston (that is, the cylinder) is R (unit mm) the radius of the piston rod is r (unit mm) the working pressure P (unit MPa) the thrust of the cylinder F push =3.14*R*R*P (unit N) The pulling force of the cylinder F pull =3.14* (R*R-r* R) *P (unit N).

How to calculate the tonnage of the hydraulic press? Example: The input cylinder pressure is 5Mpa, the end area of the cylinder piston is 100mm, and how much is the thrust tonnage?
F=P*S=5*10^6*3.14*(1/20)^2=39250N.
