(Ghana lifting hydraulic cylinder,produced by Hebei Hengyu company）

lifting hydraulic cylinder are widely used in Ghana，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed lifting hydraulic cylinder for customers from Ghana.

Introduction to lifting hydraulic cylinder:

The main role of the lifting hydraulic cylinder: the lifting 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 lifting hydraulic cylinder realizes reciprocating motion. The structure of the lifting hydraulic cylinder has three categories: piston lifting hydraulic cylinder, plunger lifting hydraulic cylinder, swing lifting hydraulic cylinder, piston lifting hydraulic cylinder and plunger lifting hydraulic cylinder to achieve reciprocating linear motion, output speed and thrust, swing lifting hydraulic cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the lifting hydraulic cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The lifting hydraulic cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.

The lifting hydraulic cylinder should not be mixed with foreign objects during assembly, which will cause scars. Before the total assembly of the lifting hydraulic cylinder, all parts must be fully removed and cleaned. When the parts are installed with burrs or dirt, foreign objects are easily embedded into the surface of the lifting hydraulic cylinder wall due to the stiffness and the weight of the parts, causing scars.

Improve the service life of the lifting 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 lifting hydraulic cylinder (such as the lifting 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 lifting 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 lifting hydraulic cylinder inlet pipe (or return pipe) can be disassembled. Make the hydraulic oil overflow to achieve the effect of single lifting hydraulic cylinder exhaust.

How to repair the lifting hydraulic cylinder body when it is damaged: When the lifting hydraulic cylinder has trace deformation and shallow tensile marks, the lifting hydraulic cylinder is repaired by strong honing process. The heavy honing process can repair lifting hydraulic cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the lifting hydraulic cylinder can meet the technical requirements.

Answers to some questions about lifting hydraulic cylinder:

The diameter of the cylinder is 180mm and the pressure is 14mpa. How many tons can the cylinder hold?
Calculate the area of the cylinder, 3.14*9*9=254.34 square centimeters, take the approximate number of engineering, 1 mpa pressure is about 10 kg per square centimeter, 14 mpa pressure is 140 kg per square centimeter, that is 254.34*140=35607.6 kilograms, it can be known that the cylinder can be about 35 tons in theory.

How to produce good quality hydraulic cylinder?
According to the principle of quality control, it is considered from five aspects: people, machine, material, method and environment. 1, People, refers to the processing and assembly operators. Their skills, professional qualifications, literacy should meet the requirements of production. For example, do your machining workers have the required grade certificate? Do your welders have welding certificate? 2, Machine, refers to your production equipment. Production cylinders have requirements for processing equipment. For example, the piston rod requires chrome grinding. Can your equipment meet the need? 3, Material. The material you use should meet the quality requirements. For example, the sealing ring of PARK and domestic goods is different. Material is also very important. 4. Method refers to the process method. Do your processing and assembly processes meet the requirements? 5, Environment. The environment shall be neat and orderly, clean and hygienic. It is especially important for the hydraulic cylinder production enterprise environment. Can your assembly shop site be clean and dust-free? Quality inspection is also a focus of control. Products should do pressure test, leakage test. The test pressure should reach 1.25 times the design pressure. If you can't maintain pressure, what about quality? You may not be able to do the whole process of cylinder production, you can take the method of OEM. Taking advantage of the strengths of specialized manufacturers, you contract out what you need and then assemble it yourself. But the principle of quality control is the same.
