(Nepal self-locking hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）

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

Introduction to self-locking hydraulic cylinder:

When installing the self-locking hydraulic cylinder, the axial ends of the self-locking hydraulic cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the self-locking hydraulic cylinder, there is axial expansion. If the two ends of the self-locking hydraulic cylinder are fixed, all parts of the self-locking hydraulic cylinder will be deformed. When disassembling the self-locking hydraulic cylinder, it is strictly forbidden to hammer the self-locking hydraulic cylinder and the piston surface, such as the self-locking hydraulic cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.

When installing the self-locking hydraulic cylinder pipe, the pipe should be cleaned after installation, and should not pass through the self-locking hydraulic cylinder block, and the by-pass pipe must be installed in front of the oil port of the self-locking hydraulic cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the self-locking hydraulic cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the self-locking hydraulic cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.

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

When purchasing the self-locking hydraulic cylinder, try to clarify the following parameters of the self-locking hydraulic cylinder: A. self-locking hydraulic cylinder diameter, rod diameter, stroke; B. Working pressure or self-locking hydraulic cylinder load; C. Working environment temperature; D. Working medium; E. Operating speed; F. Other parameters, such as connection form, mounting size, etc. In this way, the right self-locking hydraulic cylinder type can be found accurately and quickly.

Answers to some questions about self-locking hydraulic cylinder:

Hydraulic cylinder application areas?
1, in the machine tool industry, 85% of the machine tool transmission system adopts hydraulic transmission and control. Such as grinding machine, milling machine, planer, broaching machine, press, shearing machine, and combined machine tools. 2, in the metallurgical industry, electric furnace control system, rolling mill control system, open furnace charging, converter control, blast furnace control, strip deviation and constant tension device are all using hydraulic cylinders. 3, in the construction machinery, the general use of hydraulic transmission, such as excavators, tire loaders, truck cranes, crawler bulldozers, tire cranes, self-propelled scrapers, graders and vibration rollers. 4, in agricultural machinery, the use of hydraulic cylinders is also widely used, such as combine harvesters, tractors and so on.

How to calculate the hydraulic cylinder pressure? How much pressure can put up how much weight?
If you want to calculate the pressure of the cylinder, you must know the inner diameter of the cylinder, if the piston rod is needed to lift the weight, it should be: cylinder (no piston rod end) pressure = load (4000N) ÷{(PI /4)X the square of the cylinder diameter (mm) ", it has nothing to do with the piston rod diameter, the rod diameter of the piston rod is only related to the stability of the cylinder. The pressure inside the cylinder should be p=F/S=400×10/(3.14×(0.5×25)×(0.5×25))=8.15MPa which means that you need to provide at least that much pressure to complete the operation.
