Austria lifting column cylinder

(Austria lifting column cylinder,produced by Hengyu Hydraulic Co., Ltd)

lifting column cylinder are widely used in Austria,because of no need for deceleration device,long service life,smooth movement.So our company has designed lifting column cylinder for customers from Austria.

Introduction to lifting column cylinder:

If the lifting column cylinder slips or crawls, please check whether there is astringency inside the lifting column cylinder, because the internal parts of the lifting column cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, the action resistance is too large, so that the piston speed of the lifting column cylinder changes with the different stroke position, and the slip or crawl occurs. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the lifting column cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings.

When the initial action of the lifting column cylinder is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the lifting column cylinder. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.

The internal leakage of the lifting column cylinder is an important indicator to measure the quality of the lifting column cylinder: the internal leakage of the lifting column cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the lifting column cylinder, so that the lifting column cylinder can not accurately and stably stop in a certain position of the lifting column cylinder, so it is one of the main indicators of the lifting column cylinder.

When the lifting column cylinder is installed on the main engine, the oil port piping part and the guide sleeve should be checked for oil leakage in the running test, and the earring and the middle hinge shaft bearing should be refueled.

Answers to some questions about lifting column cylinder:

How to control the speed of the cylinder?
High demand control, it is necessary to use servo closed-loop control, you can adjust the speed at will. Reference: Hydrodynamic Motion Control Practical Design Guide.

How to calculate the tonnage of the hydraulic press without konowing the diameter of the cylinder?
To know the tonnage of the hydraulic cylinder, you first need to know the working pressure of the hydraulic system, the inner diameter of the hydraulic cylinder and the outer diameter of the cylinder rod (the outer diameter of the cylinder rod is needed when calculating the hydraulic cylinder tension). The thrust of the hydraulic cylinder (that is, the force that the hydraulic cylinder can produce by extending out) = the cross-sectional area of the hydraulic cylinder (or the cross-sectional area of the piston) × the working pressure of the cylinder (the cross-sectional area of the piston) =pi*D^2/4= PI (take 3.14) × the square of the cross-sectional area of the piston ÷4 working pressure to see the pressure displayed on the pressure gauge when the maximum load is working.
