(Singapore track steering cylinder,produced by Hebei Hengyu company）

track steering cylinder are widely used in Singapore，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed track steering cylinder for customers from Singapore.

Introduction to track steering cylinder:

track steering 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 track steering 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.

The definition of the minimum stable speed refers to the minimum movement speed of the track steering cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the track steering cylinder that undertakes different work has different requirements for the minimum stable speed.

If the piston rod and track steering cylinder are stuck or the track steering cylinder is blocked, at this time, no matter how to operate, the track steering cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the track steering cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

When installing the track steering cylinder pipe, the pipe should be cleaned after installation, and should not pass through the track steering cylinder block, and the by-pass pipe must be installed in front of the oil port of the track steering cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the track steering cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the track steering cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.

Answers to some questions about track steering cylinder:

How to calculate the speed of cylinder weight decline?
To reduce the weight of the cylinder, the necessary condition is that the weight of the piston rod + external load is greater than the friction between the seal ring and the cylinder. There are many reasons for this, first of all, consider the reasons of the cylinder itself, the piston in the cylinder and the sealing ring on the piston rod will play a reaction force on the weight of the cylinder (because of friction), which depends on the tightness of the sealing ring and the cylinder. Secondly, what is connected under the piston rod of the cylinder and how much weight there is. And the way the cylinders are arranged, is it completely vertical. Anyway, in fact, the most important thing is to see how much the bore of the oil hole of the piston rod cavity of your cylinder is. For example, if the hole in the lower chamber of the cylinder is small, as thin as a needle, then its descent rate will be slow.

What is the reason why the hydraulic cylinder is not good at lifting?
There may be several situations 1, whether the slow one is worn 2, whether there is air in the slow cylinder 3, if the two cylinders are supplied by the same oil port, whether the slow joint is blocked (some processing residue will reach a certain oil port under a certain coincidence condition, This situation will not happen if it is not necessarily good before) 4, the oil seal in the slow cylinder leaks, causing the feed oil to leak from the return oil end. Point 4 is most likely because it is invisible and a technical failure. If it is a dual oil feed (separate oil feed), it is also necessary to check the oil supply system and the oil return system (valve type).
