(Belarus tailboard balance cylinder,produced by Hengyu Hydraulic Co., Ltd）

tailboard balance cylinder are widely used in Belarus，because of long service life，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed tailboard balance cylinder for customers from Belarus.

Introduction to tailboard balance cylinder:

If the seal of the tailboard balance 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 tailboard balance cylinder, and the phenomenon of "pulling the tailboard balance 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.

When the tailboard balance cylinder is customized, if there are high requirements for the quality of the tailboard balance cylinder, it is best to use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface of the small crack, preventing the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the tailboard balance cylinder can be improved. By rolling forming, a cold working hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the inner wall of the tailboard balance cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.

tailboard balance cylinder can not drive the load troubleshooting: oil pressure is too low. tailboard balance cylinder selection specifications are too small. Leakage in tailboard balance cylinder or associated hydraulic system element.

tailboard balance cylinder is the most important part of construction machinery, the traditional processing method is: broaching tailboard balance cylinder block - fine boring tailboard balance cylinder block - grinding tailboard balance cylinder block. The rolling method is: broaching tailboard balance cylinder block - fine boring tailboard balance cylinder block - rolling tailboard balance cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the tailboard balance cylinder block is about 1-2 days, rolling 1 meter of the tailboard balance cylinder block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3 μm before rolling to Ra0.4 ~ 0.8μm, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the tailboard balance cylinder increases by 25%. If the tailboard balance cylinder life is only considered, it is increased by 2 to 3 times, and the boring and rolling process is 3 times more efficient than the grinding process In particular, if you want to make high-quality tailboard balance cylinders, you must take the rolling production process. After the tailboard balance cylinder is rolled, there is no sharp tiny edge on the surface, and long-term motion friction will not damage the seal ring or seal, which is particularly important in the hydraulic industry.

Answers to some questions about tailboard balance cylinder:

When does the cylinder rotate?
The piston rod inside the multistage plunger cylinder can be rotated, and it will rotate when it is subjected to tangential force.

What are the causes of hydraulic cylinder oil leakage?
First, between the piston rod and the guide sleeve: 1, the cylinder force is not good, there is a radial force between the piston rod and the guide sleeve there is a partial load, so that the oil seal is worn early, causing oil leakage. 2. The ambient temperature of the piston rod is high, especially radiant heat, and the oil seal aging is fast. 3. Whether the oil seal is selected correctly; Check whether the oil seal is damaged during installation. 4, guide sleeve and piston rod matching tolerance is correct. Second, between guide sleeve and cylinder: 1. Whether the O-ring on the guide sleeve is installed correctly, pay special attention to the O-ring can not "roll", especially some O-rings are die-pressed with a die-closing line. Third, common problems: 1, guide sleeve, cylinder, piston rod concentricity is poor. Fit tolerance is correct.
