El Salvador tailboard balance cylinder

(El Salvador tailboard balance cylinder,produced by Hengyu Group)

tailboard balance cylinder are widely used in El Salvador,because of clever hydraulic energy conversion,simple structure and reliable operation,excellent temperature resistance.So our company has designed tailboard balance cylinder for customers from El Salvador.

Introduction to tailboard balance cylinder:

The viscosity of the working oil used in the tailboard balance cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.

The piston seal of the tailboard balance cylinder is the main element to prevent leakage in the tailboard balance cylinder. For the lip seal, it should focus on checking whether the lip edge is bruised and worn, and for the combination seal, it should focus on checking the wear of the sealing surface, and then determine whether the seal can be used. In addition, it is necessary to check whether the static seal between the piston and the piston rod is crushed. The piston rod seal should focus on checking the wear of the seals and supporting rings.

tailboard balance cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the tailboard balance cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the tailboard balance cylinder. c. The tailboard balance cylinder seal is extruded, if the O-ring is obviously extruded at the tailboard balance cylinder seal, replace the tailboard balance cylinder seal.

If the tailboard balance cylinder slips or crawls, please check whether there is astringency inside the tailboard balance cylinder, because the internal parts of the tailboard balance 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 tailboard balance 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 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.

Answers to some questions about tailboard balance cylinder:

Why does the hydraulic cylinder ring?
1 Air intrusion into the hydraulic system is the main reason for noise 2 The relief valve is unstable, such as due to the improper combination of the slide valve and the valve hole or the contact of the cone valve and the seat is stuck by dirt, the damping hole is blocked, the spring is crooked or fails to make the spool stuck or move in the valve hole, causing system pressure fluctuation and noise. 3 Improper adjustment of the reversing valve causes the spool of the reversing valve to move too fast, resulting in reversing impact, resulting in noise and vibration. 4 Mechanical vibration, such as long tubing, elbow more and not fixed, when the oil flow through, especially when the flow rate is high, easy to cause pipe shaking; The rotating part of the motor and hydraulic pump is unbalanced, or the alignment is not good during installation, or the coupling is loose, etc., which can produce vibration and noise.

What is hydraulic cylinder internal leakage and external leakage?
The internal leakage of the hydraulic cylinder refers to the leakage of the piston head seal of the double-acting cylinder, and the leakage occurs inside the cylinder; The external leakage refers to the leakage phenomenon between the cylinder head (or cylinder guide sleeve) and the plunger rod (or piston rod) and the seal between the guide sleeve and the cylinder block, and the oil in the hydraulic cylinder leaks to the outside.
