(Austria 200 ton hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

200 ton hydraulic cylinder are widely used in Austria，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed 200 ton hydraulic cylinder for customers from Austria.

Introduction to 200 ton hydraulic cylinder:

200 ton hydraulic cylinder spool stuck or valve hole blocked How to solve: When the flow valve or direction valve spool stuck or valve hole blocked, the 200 ton hydraulic cylinder prone to misoperation or action failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium.

When the 200 ton hydraulic cylinder needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the 200 ton hydraulic cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.

200 ton hydraulic cylinder body inspection: The inner surface of the 200 ton hydraulic cylinder and the piston seal are the main factors causing the leakage in the 200 ton hydraulic cylinder, if the 200 ton hydraulic cylinder has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the 200 ton hydraulic cylinder mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.

200 ton hydraulic cylinder is the most important part of construction machinery, the traditional processing method is: broaching 200 ton hydraulic cylinder block - fine boring 200 ton hydraulic cylinder block - grinding 200 ton hydraulic cylinder block. The rolling method is: broaching 200 ton hydraulic cylinder block - fine boring 200 ton hydraulic cylinder block - rolling 200 ton hydraulic cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the 200 ton hydraulic cylinder block is about 1-2 days, rolling 1 meter of the 200 ton 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 200 ton hydraulic cylinder increases by 25%. If the 200 ton 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 200 ton hydraulic cylinders, you must take the rolling production process. After the 200 ton 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.

Answers to some questions about 200 ton hydraulic cylinder:

The inner diameter of the injection cylinder is 203.2mm and the diameter of the screw is 63.5mm. What is the enhancement ratio?
Oil pressure multiplied by the cross-sectional area of the cylinder is equal to the theoretical output force value, and then multiplied by the efficiency of the cylinder is equal to the actual output force value, and the oil pressure can be calculated by inverting the value input.

Does the excavator use a hydraulic cylinder?
First, construction machinery is generally a hydraulic cylinder. Second, hydraulic transmission equipment is usually composed of four components, power, execution, control and auxiliary. And the hydraulic cylinder as a linear reciprocating motion or less than 360. Reciprocating motion of the hydraulic mechanism, simple structure, reliable work, is also widely used in the hydraulic system of the main actuator, it is the prime mover in the form of mechanical energy to drive the hydraulic pump produced by the liquid pressure energy, and then can be directly driven load for reciprocating movement or less than 360.
