(Ecuador servo hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to servo hydraulic cylinder:

Improve the service life of the servo hydraulic cylinder: it is necessary to maintain the normal clearance of the combined surface of the hydraulic components. When manufacturing or repairing the main parts of the servo hydraulic cylinder (such as the servo hydraulic cylinder block, piston rod, etc.), the assembly should be carried out in accordance with the tolerance lower limit of the assembly size, which can well reduce the occurrence of cavitation. If cavitation has occurred in the hydraulic components, only metallographic sandpaper polishing technology can be used to remove cavitation pitting and surface carbon deposits, and general fine sandpaper must not be used for polishing After the servo hydraulic cylinder is repaired, the hydraulic system should run smoothly for a certain period of time so that the hydraulic oil in the hydraulic system can be fully circulated; If necessary, the servo hydraulic cylinder inlet pipe (or return pipe) can be disassembled. Make the hydraulic oil overflow to achieve the effect of single servo hydraulic cylinder exhaust.

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

servo 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 servo 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 ' servo 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 servo hydraulic cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The servo hydraulic cylinder mainly outputs linear motion and force. The servo 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 servo hydraulic cylinder, plunger servo hydraulic cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger servo hydraulic cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.

If air enters the hydraulic system, the servo hydraulic cylinder will not operate normally, mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced.

Answers to some questions about servo hydraulic cylinder:

What is a mold core cylinder?
Simple plastic parts can be directly pushed out by the ejector rod after injection molding, complex plastic parts can not be directly pushed out by the ejector rod after injection molding, to make the interference part active, control its position through the cylinder (injection molding into the mold, so that the shape of the plastic parts meet the demand, exit after opening the mold, so that the plastic parts are smoothly pushed out), This kind of cylinder is the mold core cylinder.

How to control the speed of the hydraulic cylinder?
The speed of the hydraulic cylinder is only related to the flow, so the control speed is to control the flow of the hydraulic oil, which is generally adjusted by the throttle valve in the system.
