(Peru servo hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）
servo hydraulic cylinder are widely used in Peru，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed servo hydraulic cylinder for customers from Peru.
The main role of the servo hydraulic cylinder: the servo hydraulic cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the servo hydraulic cylinder realizes reciprocating motion. The structure of the servo hydraulic cylinder has three categories: piston servo hydraulic cylinder, plunger servo hydraulic cylinder, swing servo hydraulic cylinder, piston servo hydraulic cylinder and plunger servo hydraulic cylinder to achieve reciprocating linear motion, output speed and thrust, swing servo hydraulic cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the servo hydraulic cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The servo hydraulic cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.
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.
servo hydraulic cylinder spool stuck or valve hole blocked How to solve: When the flow valve or direction valve spool stuck or valve hole blocked, the servo hydraulic cylinder prone to misoperation or action failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium.
The material, shape and compression of the servo hydraulic cylinder seal have a great impact on the service life and work efficiency of the servo hydraulic cylinder. In addition to requiring a reliable seal, it should also have a long service life and less friction loss. At present, there are many seal manufacturers in the country, and it is also crucial to choose high-quality seals with reliable and stable quality.
How to determine the rated working pressure of the hydraulic cylinder?
Under normal circumstances, the working pressure is determined according to the size of the load and the installation space (the allowable diameter of the cylinder). In some special occasions, the smaller the cylinder, the better, the pressure level must be increased. The cylinder pressure is related to the estimated cost. The higher the pressure, the thicker the wall, the higher the cost, but conversely, the lower the pressure, the larger the diameter of the cylinder (when the same thrust) is required, the same high cost. Therefore, the rated pressure of the cylinder is concentrated in about 35 mpa, taking into account the cylinder diameter and wall thickness.
Need a hydraulic cylinder, vertical upward 10 seconds to lift 20 tons of weight up 2 meters, how large cylinder and rod, how much pressure to use the plunger pump and how big?
The first thing to determine the system pressure, let's say 25 mpa, can take into account cost and performance. 1 Cylinder area 20000/250=80 square cm cylinder diameter (80/3.14) squared x2=200 mm 2 cylinder volume 80x200=16000 ml =16 L 3 Required pump flow 16x60/10=96 L/min 4 Power 96x25/55=43 kW 45 kW motor is available.
