Mexico aluminum alloy cylinder

(Mexico aluminum alloy cylinder,produced by Hengyu Group)

aluminum alloy cylinder are widely used in Mexico,because of no transmission clearance,powerful torque,clever hydraulic energy conversion.So our company has designed aluminum alloy cylinder for customers from Mexico.

Introduction to aluminum alloy cylinder:

aluminum alloy cylinders in series, parallel and series parallel. Series: In the aluminum alloy 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 aluminum alloy 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 aluminum alloy 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 aluminum alloy 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 internal leakage of the aluminum alloy cylinder is an important indicator to measure the quality of the aluminum alloy cylinder: the internal leakage of the aluminum alloy cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the aluminum alloy cylinder, so that the aluminum alloy cylinder can not accurately and stably stop in a certain position of the aluminum alloy cylinder, so it is one of the main indicators of the aluminum alloy cylinder.

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

When the aluminum alloy cylinder is customized, if there are high requirements for the quality of the aluminum alloy 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 aluminum alloy 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 aluminum alloy cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.

Answers to some questions about aluminum alloy cylinder:

What is a constant velocity cylinder? What is the difference between hydraulic cylinder and constant velocity cylinder?
The constant speed cylinder should be the same as the speed of the piston rod extension and withdrawal cylinder is called the constant speed cylinder. The difference between it and the ordinary hydraulic cylinder is that the ordinary hydraulic cylinder only has a piston rod extended out, and the general extension speed is slow and the recovery speed is fast, because of the relationship between the effective area. Effective area of piston chamber > Effective area of piston rod chamber. The effective area on both sides of the constant speed cylinder is the same, because there are piston rods sticking out at both ends. The application of constant speed cylinder is most common in grinding machines.

Why is there noise in the hydraulic cylinder of the excavator lift arm?
There is no noise of a normal cylinder, check whether the throttle is ringing, or the mechanical part connected with it is ringing, and the mechanical part can be greased. If it can't be ruled out, disconnect the cylinder from the mechanical part and act alone to see what the situation is.
