Malaysia hydraulic cylinder,spring return cylinder manufacturer,spring return cylinder(Malaysia spring return cylinder,produced by Hengyu Hydraulic Co., Ltd)
spring return cylinder are widely used in Malaysia,because of no need for deceleration device,long service life,smooth movement.So our company has designed spring return cylinder for customers from Malaysia.
The "O" ring can be used as an auxiliary seal inside the spring return cylinder, and the elastic force of the "O" ring makes the sealing slip ring close to the sealing surface, generating sealing pressure to achieve sealing. When the internal hydraulic pressure increases, the "O" ring will further deform and squeeze the slip ring, thereby increasing the sealing pressure and improving the sealing performance. The structure has the characteristics of low friction coefficient, good wear resistance, automatic compensation for wear and absorption of hard particles in the spring return cylinder, and can be completely sealed.
The internal leakage of the spring return cylinder is an important indicator to measure the quality of the spring return cylinder: the internal leakage of the spring return cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the spring return cylinder, so that the spring return cylinder can not accurately and stably stop in a certain position of the spring return cylinder, so it is one of the main indicators of the spring return cylinder.
spring return cylinder daily maintenance, should focus on checking whether the piston rod surface roughness and shape and position tolerance meet the technical requirements, if the piston rod bending should be calibrated to meet the requirements or according to the physical mapping, manufactured by a professional manufacturer. If the piston rod surface coating wear, slip damage, local spalling can be adopted to remove the coating, re-chrome surface processing process.
The spring return cylinder can not be used as grounding electrode to avoid electric damage to 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.
How to calculate the tonnage of hydraulic cylinder? The tonnage of the cylinder refers to the output force of the cylinder under rated working pressure: 1, for single rod piston hydraulic cylinder, it can be calculated by the area of the circle corresponding to the inner diameter of the cylinder A (square centimeter), and the rated working pressure of the system p (mpa), the value is equal to 10pA kg force, and the ton is 0.01pA. 2, for the double rod piston hydraulic cylinder, with A(square centimeter) to indicate the cylinder cylinder diameter and piston rod outer diameter defined by the ring area, with p (mpa) to indicate the rated working pressure of the system, the output force of the cylinder is 0.01pA ton force.
