(Chile yg series hydraulic cylinder,produced by Hebei Hengyu company）

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

Introduction to yg series hydraulic cylinder:

yg series hydraulic cylinder piston rod material selection and requirements: ① piston rod is usually made of 45 steel. When there is a large impact force and heavy load transmission, it is made of 40Cr steel. This is to ensure that the piston rod has sufficient working strength. The piston rod is generally designed as a yg series hydraulic cylinder, if the diameter is larger, the hollow piston rod can be used. Made of No. 45 seamless steel pipe. ③ When the piston rod is manufactured, the blank should be first forged and conditioned after mechanical rough processing, and the hardness of HB=230 ~ 250. The purpose of conditioning is to improve the machining performance and increase the working strength of the material. ④ The surface roughness Ra of the piston rod after finishing should not be greater than 0.65μm. ⑤ In order to improve the corrosion resistance of the piston rod, the working surface of the rod can be plated with hard chromium. ⑥ The piston rod and the end cap are guided by H8 ' yg series hydraulic cylinder piston rod industry standard: piston rod diameter series of national recommended standard GB/T2348-1993. Piston rod thread size series standard GB/T2350-1980. Please refer to execute. There is no industry standard for piston rods Both the yg series hydraulic cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The yg series hydraulic cylinder mainly outputs linear motion and force. The yg series hydraulic cylinder has a variety of forms, according to the different characteristics of its mechanism it can be divided into piston type, plunger type and swing type three categories, according to the mode of action he can be divided into single action and double action. Piston yg series hydraulic cylinder, plunger yg series hydraulic cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger yg series hydraulic cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.

The yg series hydraulic cylinder should be used correctly and maintained regularly. The yg series hydraulic cylinder should be deflated before use, the buffer regulating valve should be adjusted to a reasonable position, the cleanliness of the oil should be checked regularly, the dust on the yg series hydraulic cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.

How to determine the working pressure of the yg series hydraulic cylinder: The pressure depends on the load size (i.e., F) and the type of equipment. The limitations of assembly space, economic conditions and component availability of the actuator should also be considered. In the case of a certain load, it is necessary to increase the structural size of the actuator if the working pressure is low, for some equipment, the size may be limited, and it is not economical from the point of view of material consumption; On the contrary, if the pressure selection is too high, the material, sealing and manufacturing accuracy of the pump, yg series hydraulic cylinder, valve and other components are also required to be high, which will inevitably increase the cost of equipment. In general, for equipment with a fixed size that is not too limited, the pressure can be selected lower, and the walking machinery should be selected higher.

The piston seal of the yg series hydraulic cylinder is the main element to prevent leakage in the yg series hydraulic cylinder. For the lip seal, it should focus on checking whether the lip edge is bruised and worn, and for the combination seal, it should focus on checking the wear of the sealing surface, and then determine whether the seal can be used. In addition, it is necessary to check whether the static seal between the piston and the piston rod is crushed. The piston rod seal should focus on checking the wear of the seals and supporting rings.

Answers to some questions about yg series hydraulic cylinder:

How to disassemble the big nut that excavate the oil cylinder piston of the excavator?
If you want to be safe, look for a special unloading place for this thing, which is an oil cylinder on top of a turntable with a large nut attached to the center of the turntable. If you're in the field just pin the head of the cylinder to one end, use a big homemade wrench to hold the nut in place, and then get a digging machine and push it down, and it opens.

How to calculate the inner diameter of the hydraulic cylinder?
These two parameters need the following information to decide: 1, pump displacement, speed (to get the actual output flow of the pump) 2, three and time requirements (lift time, drop time takes a few seconds) and then view the close cylinder series according to the results. Select the right cylinder.
