sanitation truck hydraulic cylinder are widely used in Dominica，because of high work efficiency，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed sanitation truck hydraulic cylinder for customers from Dominica.

Introduction to sanitation truck hydraulic cylinder:

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

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

Protection of the sanitation truck hydraulic cylinder surface: During the dismantling process, safety protection should be carried out on the sanitation truck hydraulic cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the sanitation truck hydraulic cylinder surface. In the process of propulsion, the damaged pipe segments should be prevented from falling and smashing, and the slurry remaining on the surface of the sanitation truck hydraulic cylinder should be cleaned up in time.

In recent years, the processing process of the sanitation truck hydraulic cylinder generally adopts the rolling method, which is a pressure finishing processing, which uses the cold plastic characteristics of the metal at room temperature, and uses the rolling tool to exert a certain pressure on the surface of the workpiece, so that the surface metal of the workpiece produces plastic flow, and fills in the low concave trough of the original residue, and the roughness value of the workpiece surface is reduced. Due to the plastic deformation of the rolled surface metal, the surface tissue is cold hardened and the grain is fine, forming a dense fiber, and forming a residual stress layer, and the hardness and strength are increased, thus improving the wear resistance, corrosion resistance and compatibility of the workpiece surface. Rolling is a plastic machining method without cutting.

Answers to some questions about sanitation truck hydraulic cylinder:

What are the main technical parameters of the hydraulic cylinder?
Parameters are as follows: 1, cylinder diameter, inner diameter size; 2, import and export diameter and thread parameters; 3, piston rod diameter; 4, cylinder pressure, cylinder working pressure, calculation is often used test pressure, less than 16MPa multiplied by 1.5, higher than 16MPa multiplied by 1.25. 5, cylinder stroke; 6. Is there a buffer? According to the working conditions, the piston rod extension contraction is generally buffered if the impact is large. 7, the installation of the cylinder.

When the hydraulic cylinder changes from fast to slow, how can the slow speed become more even and the speed can be adjusted?
Reversing valve set 2 reversing valves. The back of one valve goes directly to the cylinder, running at full speed for fast action. Add a speed control valve behind the other valve, and then connect to the cylinder to achieve slow action, you can adjust the opening of the speed control valve, to achieve the speed of the cylinder can be adjusted. An import speed control valve to more than 1,000 yuan, if you think it is too expensive, you can also use the throttle valve instead. However, the throttle valve is greatly affected by the load change.
