UAE hydraulic cylinder,single rack cylinder manufacturer,single rack cylinder

(UAE single rack cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to single rack cylinder:

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

single rack cylinder buffer valve inspection and maintenance: For the valve buffer single rack cylinder, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.

When the control pressure of the hydraulic system is too low, the single rack 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.

single rack cylinder body inspection: The inner surface of the single rack cylinder and the piston seal are the main factors causing the leakage in the single rack cylinder, if the single rack cylinder has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the single rack cylinder mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.

Answers to some questions about single rack cylinder:

How to disassemble the big nut that excavate the oil cylinder piston of the excavator?
If you want to be safe, look for a special unloading place for this thing, which is an oil cylinder on top of a turntable with a large nut attached to the center of the turntable. If you're in the field just pin the head of the cylinder to one end, use a big homemade wrench to hold the nut in place, and then get a digging machine and push it down, and it opens.

How to calculate the cross-sectional area of hydraulic cylinder?
Hydraulic cylinder cross section integral rod cavity and rodless cavity: rod cavity is cylinder inner wall cross-sectional area - piston rod cross-sectional area; The rodless cavity is the cross-sectional area of the inner wall of the cylinder. If the working pressure p and the output force F are known, the effective cross-sectional area A=F/p can be calculated.
