(Vietnam stainless steel cylinder,produced by Hengyu Hydraulic Cylinder Factory）
stainless steel cylinder are widely used in Vietnam，because of excellent temperature resistance，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed stainless steel cylinder for customers from Vietnam.
Do not regularly check the damage of the chrome layer of the stainless steel cylinder: completely extend the stainless steel cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the stainless steel cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the stainless steel cylinder seal. Welding slag is strictly prohibited on the surface of the stainless steel cylinder.
When the stainless steel cylinder is installed, 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 stainless steel cylinder head, earring (or middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent rigid interference and cause unnecessary damage.
Do not enter foreign bodies when installing the stainless steel cylinder block. The place where the installation operation is carried out, the conditions are not good, and foreign bodies can be entered unconsciously. Therefore, the installation site must be cleaned up around, especially the place where the parts are placed must be cleaned, so that there is no dirt.
stainless steel cylinder and hydraulic station selection: Select the type and structure of the stainless steel cylinder according to the operation requirements of the main engine. According to the external load force borne by the stainless steel cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the stainless steel cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the stainless steel cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the stainless steel cylinder, the diameter of the piston and the piston rod.
PLC+ inverter + motor + pump + solenoid valve + cylinder combination, can control the accuracy of cylinder position?
In the case of extremely high accuracy requirements, you can not, please consider a few problems: 1, hydraulic oil can be compressed, it is elastic like a spring. Therefore, in the general hydraulic servo system, the valve control is far more accurate than the pump control. Because the valve can be installed very close to the hydraulic cylinder, or even installed on the hydraulic cylinder, but the pump must go through the tubing and then into the hydraulic cylinder, there is a long distance, which greatly reduces the rigidity of the system and increases the difficulty of control. 2, the quantitative pump is first of all leaking, and there is 10%-20% flow pulsation. Secondly, and more unfortunately, the leakage of the pump is related to the pressure and is non-linear.
What is the material of the lift cylinder?
The cylinder is composed of many parts. The cylinder also contains the seal and the installation port at both ends, the material of these two parts is not easy to determine if there is no physical object. The cylinder body is generally 20 steel, 45 steel, 27SiMn and other materials, and the piston rod is generally 40Cr, 45 steel and other materials.
