Azerbaijan hydraulic cylinder,limit position hydraulic cylinder manufacturer,limit position hydraulic cylinder(Azerbaijan limit position hydraulic cylinder,produced by Hebei Hengyu company)
limit position hydraulic cylinder are widely used in Azerbaijan,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed limit position hydraulic cylinder for customers from Azerbaijan.
Protection of the limit position hydraulic cylinder surface: During the dismantling process, safety protection should be carried out on the limit position hydraulic cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the limit position hydraulic cylinder surface. In the process of propulsion, the damaged pipe segments should be prevented from falling and smashing, and the slurry remaining on the surface of the limit position hydraulic cylinder should be cleaned up in time.
limit position hydraulic 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 limit position hydraulic cylinder should be used correctly and maintained regularly. The limit position hydraulic 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 limit position hydraulic cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.
The machining accuracy of the limit position hydraulic cylinder depends on the level of equipment, production technology and testing means. limit position hydraulic cylinder processing methods are commonly used in two ways, one is rough boring - fine boring - rolling, generally with 45# seamless steel pipe, this method of processing quality is good, but the cost is high. Another method is to use 20# cold-drawn seamless steel pipe, and then honing, the cost is lower. The piston rod must be adjusted and straightened before processing, and the coating thickness of the piston rod is generally not less than 0.03mm. The piston must be machined in strict accordance with the groove size and tolerance requirements given in the seal manual.
How to calculate the tonnage of the hydraulic press? Example: The input cylinder pressure is 5Mpa, the end area of the cylinder piston is 100mm, and how much is the thrust tonnage?
F=P*S=5*10^6*3.14*(1/20)^2=39250N.
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.
