(Sweden 500 ton hydraulic cylinder,produced by Hebei Hengyu company）

500 ton hydraulic cylinder are widely used in Sweden，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed 500 ton hydraulic cylinder for customers from Sweden.

Introduction to 500 ton hydraulic cylinder:

Repair method of small range wear of oil 500 ton hydraulic cylinder: 1. Use oxygen-acetylene flame to bake the scratched part (master the temperature, avoid surface annealing), bake the oil on the metal surface all the year round until no sparks splash; 2. The scratched part is treated with an Angle grinder, the grinding depth is more than 1 mm, and the groove is polished along the guide rail, preferably a dovetail groove. Scratch both ends of the drilling deeper, change the force situation; 3. Clean the surface with absorbent cotton dipped in acetone or anhydrous ethanol.

500 ton hydraulic cylinder piston rod material introduction: In general, we use 45 steel to produce 500 ton hydraulic cylinder piston rod. It has a large impact force when it is used, and some good performance steel are also used in the heavy load transmission. In order to have enough work intensity when using, and can ensure normal use, this is still more critical to have a detailed understanding of the material.

500 ton hydraulic cylinder is the most important part of construction machinery, the traditional processing method is: broaching 500 ton hydraulic cylinder block - fine boring 500 ton hydraulic cylinder block - grinding 500 ton hydraulic cylinder block. The rolling method is: broaching 500 ton hydraulic cylinder block - fine boring 500 ton hydraulic cylinder block - rolling 500 ton hydraulic cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the 500 ton hydraulic cylinder block is about 1-2 days, rolling 1 meter of the 500 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 500 ton hydraulic cylinder increases by 25%. If the 500 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 500 ton hydraulic cylinders, you must take the rolling production process. After the 500 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.

500 ton hydraulic cylinders in series, parallel and series parallel. Series: In the 500 ton 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 500 ton 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 500 ton 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 500 ton 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.

Answers to some questions about 500 ton hydraulic cylinder:

What valve is used to control the speed of the cylinder?
Hydraulic cylinder for lifting is generally the piston rod downward installation, to achieve the fast and slow speed of the cylinder, you can add a two-digit three-way electromagnetic reversing valve + a throttle valve on a branch at the bottom of the cylinder, you can achieve speed change, control mode can be controlled by time control can also be controlled by stroke switch. If you want to achieve more accurate control can use proportional valve control.

A hydraulic system functions three cylinders to maintain pressure, what components need to be used?
Two way cartridge valve can be selected for control. Two way cartridge valve advantages: 1) flow capacity is large, especially suitable for large flow occasions. 2) The spool has sensitive action and strong anti-clogging ability. 3) Good sealing, small leakage, oil flow through the valve pressure loss is small. 4) Simple structure, easy to standardize.
