Portugal track steering cylinder

(Portugal track steering cylinder,produced by Hengyu Hydraulic Co., Ltd)

track steering cylinder are widely used in Portugal,because of long service life,smooth movement,high work efficiency.So our company has designed track steering cylinder for customers from Portugal.

Introduction to track steering cylinder:

When the control pressure of the hydraulic system is too low, the track steering cylinder will appear wrong or no action, because the throttle resistance in the control pipeline may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is interfered with. At this time, check the control pressure source to ensure that the pressure is adjusted to the specified value of the system.

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

If the seal of the track steering cylinder is abnormal wear, you can check whether the speed control valve is improperly adjusted, resulting in too high back pressure and improper installation of the seal or hydraulic oil contamination. The second is whether there is a foreign body entering the assembly and the quality of the sealing material is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and track steering cylinder, and the phenomenon of "pulling the track steering cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operation and improvement should be done according to the installation instructions.

If the track steering cylinder is sliding or crawling (stop and go), check whether there is any astringency inside the track steering cylinder. The internal parts of the track steering cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, and the action resistance is too large, so that the piston speed of the track steering cylinder changes with the different stroke position, and there is slip or crawl. 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 track steering 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. At the same time, check whether the lubrication is good or whether the track steering cylinder bore processing is out of whack. Because the piston and track steering cylinder, guide rail and piston rod are relative If the track steering cylinder is crawling seriously, check whether air has entered the hydraulic system. Air compression or expansion can cause the piston to slip or crawl. The exclusion measures are to check the hydraulic pump, set up a special exhaust device, and quickly operate the exhaust several times in the full stroke. Check the seals at the same time, because the quality of the seals is directly related to slippage or crawling. When the O-ring is used under low pressure, compared with the U-ring, it is easy to slip or crawl because of the higher surface pressure and the larger difference between static and static friction resistance. The surface pressure of the U-shaped sealing ring increases with the increase of pressure, although the sealing effect is correspondingly improved, but the difference between static and static friction resistance is also larger, the internal pressure increases, affecting the rubber elasticity, due to the increase in the contact resistance of the lip, the sealing ring will tip over and the lip elongation, and it is also easy to cause slip or crawling track steering cylinder weight composition and calculation. The weight of the track steering cylinder is composed of the track steering cylinder diameter, the outer diameter and weight of the track steering cylinder, the rod diameter, and the weight of the accessories, so in calculation, it is to add all these together to get the specific value. However, if there are special circumstances, it may be calculated separately. This work can be carried out by yourself, but it can also be carried out by professionals, so that mistakes can be avoided.

Answers to some questions about track steering cylinder:

What is the cylinder with rod cavity, what is the rodless cavity.
The rod cavity is the end of the piston rod, the rodless cavity is the end without the piston rod.

What is the cause of the sound of the excavator arm cylinder?
Hydraulic excavator cylinder includes boom cylinder, bucket rod cylinder and bucket cylinder, four cylinders. The sound of boom cylinder may be the wear of hydraulic cylinder block bushing, piston rod bushing and shaft pin. The main reason: poor lubrication, followed by improper clearance in the assembly process. Countermeasures: (1) Strictly lubricate each shaft pin at least once every 8 hours when the excavator is initially used for 100 hours and under harsh conditions; In other working conditions, lubricate each pin at least once every 50 hours. (2) If the lubricating oil passage is found to be blocked, it must be stopped for rectification. (3) Require assembly, replacement of all parts of the shaft pin, bushing strictly comply with the assembly testing standards and operating procedures.
