Argentina hydraulic cylinder,large long cylinder manufacturer,large long cylinder
(Argentina large long cylinder,produced by Hengyu Hydraulic Cylinder Factory）
large long cylinder are widely used in Argentina，because of no need for deceleration device，long service life，smooth movement.So our company has designed large long cylinder for customers from Argentina.
How to repair the large long cylinder body when it is damaged: When the large long cylinder has trace deformation and shallow tensile marks, the large long cylinder is repaired by strong honing process. The heavy honing process can repair large long 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 large long cylinder can meet the technical requirements.
The advantages and disadvantages of the large long cylinder: the surface of the large long cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the large long 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.
The large long cylinder should be used correctly and maintained regularly. The large long cylinder should be deflated before use, the buffer regulating valve should be adjusted to a reasonable position, the cleanliness of the oil should be checked regularly, the dust on the large long cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.
The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the large long cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.
In a hydraulic system, a hydraulic pump has many hydraulic cylinders and hydraulic motors, and these executive components do not coordinate their actions with each other.
A load-sensitive variable pump can be used if these components sometimes need to work simultaneously and the power required is large. The required flow is distributed by the multi-way reversing valve, and the required flow and pressure changes are automatically adjusted by the hydraulic pump. Pressure reducing valves can be used for particularly low pressure circuits. Because you execute more components, the use of quantitative pump will cause a waste of energy, the system heat is large, not suitable.
How to select swing cylinder? Under what conditions are they designed and selected?
1, determine the system parameters: ① the weight and the required force; ② Nominal working pressure and range; ③ The time required to travel this distance; 4 oil medium 2, installation method: select the appropriate way for the specific application 3, cylinder diameter and working pressure: determine the cylinder diameter and provide the necessary force required by the system pressure 4, piston rod: determine the minimum piston rod diameter required to withstand the longitudinal bending force, select the appropriate piston rod end and piston rod end thread 5, piston: Whether the seal type is suitable for the application 6, buffer: choose the buffer requirements as appropriate.
