Slovenia hydraulic cylinder,adjustable stroke cylinder manufacturer,adjustable stroke cylinder

(Slovenia adjustable stroke cylinder,produced by Hebei Hengyu company）

adjustable stroke cylinder are widely used in Slovenia，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed adjustable stroke cylinder for customers from Slovenia.

Introduction to adjustable stroke cylinder:

The main role of the adjustable stroke cylinder: the adjustable stroke cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the adjustable stroke cylinder realizes reciprocating motion. The structure of the adjustable stroke cylinder has three categories: piston adjustable stroke cylinder, plunger adjustable stroke cylinder, swing adjustable stroke cylinder, piston adjustable stroke cylinder and plunger adjustable stroke cylinder to achieve reciprocating linear motion, output speed and thrust, swing adjustable stroke cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the adjustable stroke cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The adjustable stroke cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.

adjustable stroke 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 adjustable stroke 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.

How the cavitation of the adjustable stroke cylinder is formed: With the gradual rise of pressure, the gas in the oil will become bubbles, when the pressure rises to a certain limit value, these bubbles will break under the action of high pressure, so that the high temperature and high pressure gas will quickly act on the surface of the parts, resulting in cavitation of the adjustable stroke cylinder, resulting in corrosive damage to the parts.

If it is found that the adjustable stroke cylinder lubrication is poor or the adjustable stroke cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the adjustable stroke cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the adjustable stroke cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the adjustable stroke cylinder center line. In this way, when the piston works in the adjustable stroke cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the adjustable stroke cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

Answers to some questions about adjustable stroke cylinder:

How many kilograms can the 63 cylinder hold?
The force of the cylinder is related to the cylinder diameter and pressure. 63 cylinder diameter (cylinder inner circle diameter), 21MPA pressure, thrust 6 tons.

When there is only one hole in the oil inlet and outlet of the hydraulic cylinder, will there be oil leakage?
It is a single acting oil cylinder. This oil cylinder is always driven by hydraulic oil in advance, and is generally pulled back by the spring at the bottom of the piston or the weight of the cylinder piston or the load. But either way, it has nothing to do with any internal leakage. Whether the oil is internally drained is related to the sealing and accuracy of the cylinder itself.
