Sri Lanka hydraulic cylinder,aluminum alloy cylinder manufacturer,aluminum alloy cylinder
(Sri Lanka aluminum alloy cylinder,produced by Hengyu Hydraulic Co., Ltd）
aluminum alloy cylinder are widely used in Sri Lanka，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed aluminum alloy cylinder for customers from Sri Lanka.
aluminum alloy cylinder piston sealing is best to use Yx ring, polyurethane and polytetrafluoroethylene sealing material combination, can significantly improve the sealing performance: (I), reduce friction resistance, no crawling phenomenon; (ii) Have good dynamic and static sealing, wear resistance, long service life; (iii) The installation groove is simple, and the disassembly is simple.
When installing the aluminum alloy cylinder, the axial ends of the aluminum alloy cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the aluminum alloy cylinder, there is axial expansion. If the two ends of the aluminum alloy cylinder are fixed, all parts of the aluminum alloy cylinder will be deformed. When disassembling the aluminum alloy cylinder, it is strictly forbidden to hammer the aluminum alloy cylinder and the piston surface, such as the aluminum alloy cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.
The coordination of the sliding parts of the aluminum alloy cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.
aluminum alloy cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the aluminum alloy cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the aluminum alloy cylinder. c. The aluminum alloy cylinder seal is extruded, if the O-ring is obviously extruded at the aluminum alloy cylinder seal, replace the aluminum alloy cylinder seal.
What is the principle of electric cylinder?
Principle: The electric cylinder converts the rotating motion of the motor into the linear motion of the push rod through the mechanical movement of the lead screw and the lead screw pair. With the closed-loop control characteristic of servo motor, the precise control of thrust, speed and position can be realized easily. Using modern motion control technology, numerical control technology and bus (network) technology, the program and bus (network) control is realized. Because of its easy control and use, it will realize the precision motion control that the cylinder and hydraulic cylinder drive can not achieve. Electric cylinder application field: 1, coordinate manipulator: logistics transmission, automated production line. 2. Wave making machine. 3, parallel mechanism: experimental platform, simulation platform, antenna. 4. Parallel machine tools. 5. Medical equipment: CT, Kamar
How to calculate hydraulic cylinder thrust?
Cylinder diameter = piston diameter =200MM Piston area =π (200/2) square =3140 square mm =31.4 square cm 25MPA=250KG/ square cm Maximum thrust = pressure * Piston area =250 *31.4 =7850KG=78500 Newtons This is the maximum thrust. The formula can be derived from the calculation formula.
