(Puerto Rico yg series hydraulic cylinder,produced by Hengyu Group）

yg series hydraulic cylinder are widely used in Puerto Rico，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 Puerto Rico.

Introduction to yg series hydraulic cylinder:

After chrome plating of the piston rod of the yg series hydraulic cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.

yg series hydraulic cylinder and hydraulic station selection: Select the type and structure of the yg series hydraulic cylinder according to the operation requirements of the main engine. According to the external load force borne by the yg series hydraulic cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the yg series hydraulic cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the yg series hydraulic cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the yg series hydraulic cylinder, the diameter of the piston and the piston rod.

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.

If the seal of the yg series hydraulic cylinder is abnormal wear, you can check whether the speed control valve is improperly adjusted, resulting in too high back pressure and improper installation of the seal or hydraulic oil contamination. The second is whether there is a foreign body entering the assembly and the quality of the sealing material is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and yg series hydraulic cylinder, and the phenomenon of "pulling the yg series hydraulic cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operation and improvement should be done according to the installation instructions.

Answers to some questions about yg series hydraulic cylinder:

How long can a hydraulic cylinder work continuously?
If the maintenance is good, the service life can be extended a lot. The life of the cylinder is related to the structure of the cylinder, working pressure, stress state, hydraulic oil cleanliness, oil temperature control, maintenance and preventive measures. For example, the cylinder structure, the inner wall of the cylinder has quilting, rolling, chrome plating and other methods, the sealing parts have polyurethane rings, glay rings, metal sealing rings, etc., different combinations, the life difference is dozens of times. Metallurgical system is a typical cylinder application, in 24 hours of work, a year or more can not be shut down, in the middle of continuous work.

How does the one-way solenoid valve control the hydraulic cylinder circuit?
If your cylinder is single-acting, you can use a one-way solenoid valve, such as some lifting platform hydraulic cylinder, the support valve used is one-way (two-position tee), that is, the cylinder extends out by the oil pressure top, the cylinder retracted by its own weight.
