Finland hydraulic cylinder,tailplate hydraulic cylinder manufacturer,tailplate hydraulic cylinder(Finland tailplate hydraulic cylinder,produced by Hebei Hengyu company)
tailplate hydraulic cylinder are widely used in Finland,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed tailplate hydraulic cylinder for customers from Finland.
Disassembly tailplate hydraulic cylinder: When disassembly tailplate hydraulic cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the tailplate hydraulic cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the tailplate hydraulic cylinder.
tailplate hydraulic cylinder hydraulic oil selection: The recommended working oil viscosity of the tailplate hydraulic 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.
When installing the tailplate hydraulic cylinder, the axial ends of the tailplate hydraulic cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the tailplate hydraulic cylinder, there is axial expansion. If the two ends of the tailplate hydraulic cylinder are fixed, all parts of the tailplate hydraulic cylinder will be deformed. When disassembling the tailplate hydraulic cylinder, it is strictly forbidden to hammer the tailplate hydraulic cylinder and the piston surface, such as the tailplate 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.
The advantages and disadvantages of the tailplate hydraulic cylinder: the surface of the tailplate hydraulic cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the tailplate hydraulic cylinder through the top heat treatment, high manufacturing precision, belongs to the precision machinery, has a simple structure, stable quality, high mechanical efficiency, easy to achieve automation and many other advantages. However, hydraulic technology also has the shortcomings of oil leakage, oil temperature change affecting the control of running speed, noise, expensive cost and high maintenance cost.
Are hydraulic cylinders divided into oil cylinders and water cylinders? What's the difference between the two types?
There are oil cylinders and water cylinders. The two cylinders are used in different environments. Oil cylinders are generally used in places where there is less demand for media, which is our most common hydraulic cylinders. Water cylinders are mainly used for large tonnage presses. Because the equipment is too large, the use of hydraulic oil will cause a relatively large waste. However, water is not pure water, there are oil-in-water emulsion and water-in-oil emulsion. Water has another benefit: it's flame retardant. It is especially suitable for some flammable and explosive occasions. Or with water glycol. The use of pure water is very little, mainly because the seal is not good and easy to rust.
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.
