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

yg series hydraulic cylinder are widely used in Oman，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed yg series hydraulic cylinder for customers from Oman.

Introduction to yg series hydraulic cylinder:

The difference between the plunger yg series hydraulic cylinder and the piston yg series hydraulic cylinder is that the piston in the yg series hydraulic cylinder is replaced by a shaft plunger, which is used in hydraulic transmission requiring a long mechanical stroke, and can only input pressure oil from one direction, pressurize in a single direction, and form a thrust to push the plunger to move. The return trip of the plunger depends on the plunger itself to fall, and some rely on the spring to push back to the original position. Usually used plunger type yg series hydraulic cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.

Under normal circumstances, the yg series hydraulic cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the yg series hydraulic cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the yg series hydraulic cylinder and the end cover, the piston and the piston rod, the piston and the yg series hydraulic cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the yg series hydraulic cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

yg series hydraulic cylinder is the most important part of construction machinery, the traditional processing method is: broaching yg series hydraulic cylinder block - fine boring yg series hydraulic cylinder block - grinding yg series hydraulic cylinder block. The rolling method is: broaching yg series hydraulic cylinder block - fine boring yg series hydraulic cylinder block - rolling yg series hydraulic cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the yg series hydraulic cylinder block is about 1-2 days, rolling 1 meter of the yg series 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 yg series hydraulic cylinder increases by 25%. If the yg series 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 yg series hydraulic cylinders, you must take the rolling production process. After the yg series 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 quality of the yg series hydraulic cylinder can not be ignored in the purchase of the yg series hydraulic cylinder. The yg series hydraulic cylinder is the main component of the yg series hydraulic cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. yg series hydraulic cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of yg series hydraulic cylinder is deep hole processing, which has always troubled the processing personnel.

Answers to some questions about yg series hydraulic cylinder:

How does the cylinder work?
Hydraulic transmission principle: oil as the working medium, through the change of the sealing volume to transfer movement, through the internal pressure of the oil to transfer power. 1. The power part - converts the mechanical energy of the prime mover into the pressure energy of the oil (hydraulic energy). For example: hydraulic pump. 2, the executive part - the hydraulic pump input oil pressure energy into the mechanical energy to drive the working mechanism. For example: hydraulic cylinder, hydraulic motor. 3, the control part - used to control and adjust the oil pressure, flow and flow direction. For example: pressure control valve, flow control valve and direction control valve. 4, the auxiliary part - the first three parts are connected together to form a system, which plays the role of oil storage, filtration, measurement and sealing.

How to use a solenoid valve to control the expansion of a cylinder? Doesn't the solenoid valve only control on/off?
Use the solenoid valve P into A-B (generally equipped with oil circuit board) to connect the oil inlet interface at both ends of the cylinder, and the solenoid valve can be realized by power off (refer to the solenoid valve 2B2L, different solenoid valve actions are different).
