Pakistan hydraulic cylinder,series synchronous cylinder manufacturer,series synchronous cylinder

(Pakistan series synchronous cylinder,produced by Hengyu Hydraulic Cylinder Factory）

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

Introduction to series synchronous cylinder:

Disassembly series synchronous cylinder: When disassembly series synchronous cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the series synchronous cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the series synchronous cylinder.

When the series synchronous cylinder is in use, ensure that the series synchronous cylinder and the surrounding environment should be clean. The tank should be sealed to prevent contamination. Pipelines and fuel tanks should be cleaned to prevent falling off the oxide sheet and other debris. Clean with lint-free cloth or special paper. Twine and binder should not be used as sealing materials. Hydraulic oil according to the design requirements, pay attention to the change of oil temperature and oil pressure. When there is no load, unscrew the exhaust bolt for exhaust.

The viscosity of the working oil used in the series synchronous 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.

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

Why does excavator cylinder oil leak?
Under normal circumstances, the leakage of hydraulic cylinders is divided into internal leakage and external leakage. The external leakage is generally due to damage to the oil seal at the extended end of the piston rod and needs to be replaced. Internal leakage is generally because the oil seal on the piston is damaged, you can try to replace the oil seal here, if the replacement will also leak, then check whether there is damage to the inner wall of the cylinder.

In a hydraulic system, a hydraulic pump has many hydraulic cylinders and hydraulic motors, and these executive components do not coordinate their actions with each other.
A load-sensitive variable pump can be used if these components sometimes need to work simultaneously and the power required is large. The required flow is distributed by the multi-way reversing valve, and the required flow and pressure changes are automatically adjusted by the hydraulic pump. Pressure reducing valves can be used for particularly low pressure circuits. Because you execute more components, the use of quantitative pump will cause a waste of energy, the system heat is large, not suitable.
