Holland stroke adjustable cylinder

(Holland stroke adjustable cylinder,produced by Hengyu Group)

stroke adjustable cylinder are widely used in Holland,because of simple structure and reliable operation,excellent temperature resistance,no transmission clearance.So our company has designed stroke adjustable cylinder for customers from Holland.

Introduction to stroke adjustable cylinder:

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

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

The difference between the integral stroke adjustable cylinder and the split stroke adjustable cylinder: The integral stroke adjustable cylinder and the split stroke adjustable cylinder in the stroke adjustable cylinder are two different stroke adjustable cylinders, and they are very different. The whole stroke adjustable cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split stroke adjustable cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and stroke adjustable cylinder damage. Therefore, it is obvious that the answer to this question is for difference.

In order to ensure the service life of the stroke adjustable cylinder, the hydraulic system must be set up effective filtration to prevent pollution, the cleanliness of the oil should meet the ISO4406 standard, and the quality of the filtration should also meet the corresponding standards in ISO. The grade requirements of the filter are performed according to the actual working conditions of the system, but the minimum requirements are not less than 19/15 in ISO4406, that is, 24μ (β10≥75) in ISO4572.

Answers to some questions about stroke adjustable cylinder:

Servo cylinder control principle
The electro-hydraulic pulse servo cylinder is composed of a stepper motor, a three-position four-way servo valve, a mechanical feedback device (a wire carrier) and an oil lever. When the stepper motor gets a pulse signal, its output shaft rotates 1.5 or 3 degrees, the servo valve spool drives the wire to rotate at the same time, the valve spool moves and opens the reversing cylinder to output pressure oil, the piston moves and drives the lead screw to reverse rotate the valve spool back to the original position, and the servo valve stops output pressure oil in the center. At this time, the cylinder moves 0.1 or 0.2mm stroke, and the displacement and speed of the cylinder travel are determined according to the given value of the electrical pulse.

Hydraulic cylinder load algorithm?
If it is thrust, load = working pressure x piston area. If it is pulling force, load = working pressure x(piston area - piston rod area).
