(Spain folding machine cylinder,produced by Hengyu Group）

folding machine cylinder are widely used in Spain，because of smooth movement，no need for deceleration device，long service life.So our company has designed folding machine cylinder for customers from Spain.

Introduction to folding machine cylinder:

When installing the piston rod, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the folding machine cylinder head adn the earring (or the middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent the phenomenon of rigid interference and causing unnecessary damage.

folding machine cylinder hydraulic oil selection: The recommended working oil viscosity of the folding machine cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.

The body of the folding machine cylinder on the processing process requirements: the body of the folding machine cylinder is an important and essential part of the folding machine cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the folding machine cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.

Factors that should be considered when selecting the oil seal in the folding machine cylinder: some specific factors should be taken into account when selecting the oil seal in the folding machine cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: folding machine cylinder diameter, piston rod diameter, piston rod and piston groove size, folding machine cylinder working pressure, folding machine cylinder movement speed, hydraulic system oil temperature and folding machine cylinder working environment.

Answers to some questions about folding machine cylinder:

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.

How to set up the one-way cylinder hydraulic system?
Single acting oil cylinder, that is, an oil cylinder with an oil port, can use two three-way valves to control the cylinder action. The three oil ports are respectively connected to P (oil pump), A (oil cylinder), and T (oil tank). If the oil pump is to run continuously, an electromagnetic relief valve can be added. When the cylinder is not moving, the relief valve can unload the oil pump. You can also add a three-way four-way valve, the middle function is unloaded, two outlets: A connected to the fuel tank, B connected to the cylinder.
