(Singapore stroke adjustable cylinder,produced by Hengyu Group）

stroke adjustable cylinder are widely used in Singapore，because of smooth movement，no need for deceleration device，long service life.So our company has designed stroke adjustable cylinder for customers from Singapore.

Introduction to stroke adjustable cylinder:

stroke adjustable 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 stroke adjustable cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the stroke adjustable cylinder. c. The stroke adjustable cylinder seal is extruded, if the O-ring is obviously extruded at the stroke adjustable cylinder seal, replace the stroke adjustable cylinder seal.

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 stroke adjustable cylinder action. Troubleshooting method: Replace the rubber hose.

In order to ensure the service life of the stroke adjustable cylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the stroke adjustable cylinder, causing damage to the seal and causing leakage in the stroke adjustable cylinder. It is required that the filtration accuracy of the system is not less than 80μm, the oil pollution is strictly controlled, the hydraulic oil is kept clean, the performance of the hydraulic oil is regularly checked, and the necessary fine filtration or replacement of the new working hydraulic oil is carried out.

stroke adjustable cylinder is the most important part of construction machinery, the traditional processing method is: broaching stroke adjustable cylinder block - fine boring stroke adjustable cylinder block - grinding stroke adjustable cylinder block. The rolling method is: broaching stroke adjustable cylinder block - fine boring stroke adjustable cylinder block - rolling stroke adjustable cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the stroke adjustable cylinder block is about 1-2 days, rolling 1 meter of the stroke adjustable 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 stroke adjustable cylinder increases by 25%. If the stroke adjustable 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 stroke adjustable cylinders, you must take the rolling production process. After the stroke adjustable 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 stroke adjustable cylinder:

What does cylinder hob125*100 mean?
HOB is a series of hydraulic cylinder products, the use of pressure 14MPA, tie rod structure. 125 refers to the diameter of the cylinder and 100 refers to the stroke. The unit is millimeters.

What's the use of three oil pipes on the cylinder?
The cylinder usually has an upper and lower oil chamber, one is connected to the upper oil chamber, one is connected to the lower oil chamber, sometimes a hydraulic lock will be added, that is, a hydraulic control check valve to prevent accidents when the oil pipe breaks, so the third pipe should be the control oil pipe of the hydraulic control check valve.
