(Portugal pusher hydraulic cylinder,produced by Hengyu Group）

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

Introduction to pusher hydraulic cylinder:

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

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

The body of the pusher hydraulic cylinder on the processing process requirements: the body of the pusher hydraulic cylinder is an important and essential part of the pusher hydraulic cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the pusher hydraulic cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.

When the pusher hydraulic cylinder is installed, the piston and the pusher hydraulic cylinder head and other parts have large mass, large size and large inertia, even if there is a lifting equipment auxiliary installation, because the specified clearance is small, no matter how hard it will be put into, therefore, the end of the piston or the pusher hydraulic cylinder head boss is easy to cause scars when it hits the inner surface of the pusher hydraulic cylinder wall. The solution to this problem: for a large number of small products, the use of autocratic assembly oriented tools during installation; For heavy, thick and large large and medium-sized pusher hydraulic cylinders, only careful and careful operation can be avoided.

Answers to some questions about pusher hydraulic cylinder:

What is the material of the lift cylinder?
The cylinder is composed of many parts. The cylinder also contains the seal and the installation port at both ends, the material of these two parts is not easy to determine if there is no physical object. The cylinder body is generally 20 steel, 45 steel, 27SiMn and other materials, and the piston rod is generally 40Cr, 45 steel and other materials.

How big is the motor and oil pump for the 80 cylinder?
Pump motor selection is not only related to cylinder diameter but also speed system, it is recommended to provide system diagram and speed requirements, generally speaking, most of the 80 cylinder on the market is equipped with 3-4KW motor, 10-20 oil pump.
