Sudan tailboard balance cylinder

(Sudan tailboard balance cylinder,produced by Hebei Hengyu company)

tailboard balance cylinder are widely used in Sudan,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed tailboard balance cylinder for customers from Sudan.

Introduction to tailboard balance cylinder:

Improve the service life of the tailboard balance cylinder: it is necessary to maintain the normal clearance of the combined surface of the hydraulic components. When manufacturing or repairing the main parts of the tailboard balance cylinder (such as the tailboard balance cylinder block, piston rod, etc.), the assembly should be carried out in accordance with the tolerance lower limit of the assembly size, which can well reduce the occurrence of cavitation. If cavitation has occurred in the hydraulic components, only metallographic sandpaper polishing technology can be used to remove cavitation pitting and surface carbon deposits, and general fine sandpaper must not be used for polishing After the tailboard balance cylinder is repaired, the hydraulic system should run smoothly for a certain period of time so that the hydraulic oil in the hydraulic system can be fully circulated; If necessary, the tailboard balance cylinder inlet pipe (or return pipe) can be disassembled. Make the hydraulic oil overflow to achieve the effect of single tailboard balance cylinder exhaust.

In the hydraulic system, sometimes the inner layer of the rubber hose is peeled off, so that the oil circuit is on and off, resulting in irregular tailboard balance cylinder action. Troubleshooting method: Replace the rubber hose.

If the tailboard balance cylinder is sliding or crawling (stop and go), check whether there is any astringency inside the tailboard balance cylinder. The internal parts of the tailboard balance 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 tailboard balance 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 tailboard balance 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 tailboard balance cylinder bore processing is out of whack. Because the piston and tailboard balance cylinder, guide rail and piston rod are relative If the tailboard balance 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 tailboard balance cylinder weight composition and calculation. The weight of the tailboard balance cylinder is composed of the tailboard balance cylinder diameter, the outer diameter and weight of the tailboard balance 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.

In the process of using the tailboard balance cylinder, sometimes such a problem will occur, the tailboard balance cylinder can not act immediately after the instruction of the tailboard balance cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil tailboard balance cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

Answers to some questions about tailboard balance cylinder:

When the hydraulic cylinder changes from fast to slow, how can the slow speed become more even and the speed can be adjusted?
Reversing valve set 2 reversing valves. The back of one valve goes directly to the cylinder, running at full speed for fast action. Add a speed control valve behind the other valve, and then connect to the cylinder to achieve slow action, you can adjust the opening of the speed control valve, to achieve the speed of the cylinder can be adjusted. An import speed control valve to more than 1,000 yuan, if you think it is too expensive, you can also use the throttle valve instead. However, the throttle valve is greatly affected by the load change.

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.
