(Cote d 'Ivoire synchronous hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）

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

Introduction to synchronous hydraulic cylinder:

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

synchronous hydraulic cylinder hydraulic oil selection: The recommended working oil viscosity of the synchronous hydraulic cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.

synchronous hydraulic cylinders in series, parallel and series parallel. Series: In the synchronous hydraulic cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Series: In the synchronous hydraulic cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Parallel: the pressure oil in the synchronous hydraulic cylinder is connected with the inlet oil of each reversing valve, and the return oil is collected by the return oil circuit. Series parallel: For this one, compared with the simple series and parallel, it is slightly more complicated, but it is not impossible to understand. The series refers to the oil in the synchronous hydraulic cylinder, which is in series form, but can not form a series circuit, and the parallel refers to the oil return circuit of each valve, which is in parallel.

The material of the sliding part of the synchronous hydraulic cylinder piston sintered casting piston will cause sintering phenomenon when subjected to large transverse load. In this case, the sliding part of the piston should be made of copper alloy or welded to such material.

Answers to some questions about synchronous hydraulic cylinder:

What are the reasons why the hydraulic cylinder action is slower than normal?
There are many factors that cause this problem. First, measure the pressure of the main system to see whether the pressure of the main system under the pressure state is consistent with the initial setting. Before measuring the pressure, it is best to check the hydraulic oil and suction oil filter and replace or clean it. Second, check the main relief valve of the reversing control multiway valve to see if there is damage or foreign matter blocking, and clean it. If your pump is a gear pump, the problem should generally be small. Second, look at traffic. There is no leakage in the cylinder, leakage in the reversing valve spool and so on.

What are the cylinder manufacturing processes?
Hydraulic cylinder processing process: 1, cylinder: a, material preparation (seamless steel pipe) → inspection (material certificate, etc.) → tempering (outsourcing: Some parts) → car (car round, shelf mouth, boring, flange stop, etc.) → tempered hardness test → welding (welded pipe joint base, flange and other accessories) → boring or honing (rough boring, fine boring, rolling) → car (hole slot or internal and external thread) → fitter (drilling) → inspection → rust prevention storage b, material preparation (forgings) → inspection (material certificate, inspection, etc.) → welding (blank butt welding) → welding inspection → car (rough car) → quality control (outsourcing: some parts) → car (car round, shelf mouth, boring stop, flange stop, etc.)
