Vietnam hydraulic cylinder,tilting furnace hydraulic cylinder manufacturer,tilting furnace hydraulic cylinder(Vietnam tilting furnace hydraulic cylinder,produced by Hengyu Group)
tilting furnace hydraulic cylinder are widely used in Vietnam,because of clever hydraulic energy conversion,simple structure and reliable operation,excellent temperature resistance.So our company has designed tilting furnace hydraulic cylinder for customers from Vietnam.
The difference between the integral tilting furnace hydraulic cylinder and the split tilting furnace hydraulic cylinder: The integral tilting furnace hydraulic cylinder and the split tilting furnace hydraulic cylinder in the tilting furnace hydraulic cylinder are two different tilting furnace hydraulic cylinders, and they are very different. The whole tilting furnace hydraulic cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split tilting furnace hydraulic cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and tilting furnace hydraulic cylinder damage. Therefore, it is obvious that the answer to this question is for difference.
Analysis of commonly used seals: The wear ring and slip ring commonly used on the tilting furnace hydraulic cylinder are generally made of polytetrafluoroethylene + graphite, because pure polytetrafluoroethylene is easy to produce plastic creep, which is only suitable for low pressure and low wear resistance conditions. If the sealing ring used is a composite material formed after adding graphite filler, the performance can be effectively improved, the ability to resist plastic creep is increased by 2 to 3 times, the initial deformation caused by the load is reduced by 30 to 60% : the rigidity is increased by 2 to 3 times: the dimensional stability under heat is increased by 2 times, and the hardness is increased by l0 to 15%.
When the tilting furnace hydraulic cylinder needs to be stored for a period of time, please follow the recommended methods: The tilting furnace hydraulic cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the tilting furnace hydraulic cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil tilting furnace hydraulic cylinder should not be in direct contact with water vapor for a long time. The tilting furnace hydraulic cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the tilting furnace hydraulic cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the tilting furnace hydraulic cylinder Before working, the tilting furnace hydraulic cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the tilting furnace hydraulic cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.
The advantages and disadvantages of the tilting furnace hydraulic cylinder: the surface of the tilting furnace hydraulic cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the tilting furnace 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.
How to select the propulsion cylinder according to the shield attitude, cylinder stroke, shield tail clearance and other factors?
Generally, the shield machine will be equipped with the corresponding cylinder. Soil pressure balancing machine, mud water balancing machine have the corresponding cylinder, there will be no insufficient cylinder force. In the jacking process of the pipe jacking machine, there are certain requirements for the jacking force of the cylinder.
Can multiple identical hydraulic cylinders be supplied with the same supply line?
This can be connected, but there is a disadvantage, that is, the hydraulic cylinder with the minimum pressure is extended first, and then the pressure is higher, and then the higher, until all the hydraulic cylinders are extended, which may not meet the requirements of field use.
