Portugal hydraulic cylinder,yg series hydraulic cylinder manufacturer,yg series hydraulic cylinder
(Portugal yg series hydraulic cylinder,produced by Hebei Hengyu company）
yg series hydraulic cylinder are widely used in Portugal，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed yg series hydraulic cylinder for customers from Portugal.
The daily inspection of the yg series hydraulic cylinder includes: checking the connection of the yg series hydraulic cylinder and the pipe joint for leaks. Check the yg series hydraulic cylinder rod for leaks. Check the yg series hydraulic cylinder connection for leaks. When the yg series hydraulic cylinder moves, the work is normal and smooth. Whether the yg series hydraulic cylinder has internal leakage.
The quality of the yg series hydraulic cylinder can not be ignored in the purchase of the yg series hydraulic cylinder. The yg series hydraulic cylinder is the main component of the yg series hydraulic cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. yg series hydraulic cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of yg series hydraulic cylinder is deep hole processing, which has always troubled the processing personnel.
yg series hydraulic cylinder hydraulic oil selection: The recommended working oil viscosity of the yg series hydraulic cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.
If the seal of the yg series hydraulic cylinder is abnormal wear, you can check whether the speed control valve is improperly adjusted, resulting in too high back pressure and improper installation of the seal or hydraulic oil contamination. The second is whether there is a foreign body entering the assembly and the quality of the sealing material is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and yg series hydraulic cylinder, and the phenomenon of "pulling the yg series hydraulic cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operation and improvement should be done according to the installation instructions.
The diameter of the cylinder is 180mm and the pressure is 14mpa. How many tons can the cylinder hold?
Calculate the area of the cylinder, 3.14*9*9=254.34 square centimeters, take the approximate number of engineering, 1 mpa pressure is about 10 kg per square centimeter, 14 mpa pressure is 140 kg per square centimeter, that is 254.34*140=35607.6 kilograms, it can be known that the cylinder can be about 35 tons in theory.
The pressure gauge of the hydraulic station reaches 20MPa. How many tons of weight can the hydraulic cylinder lift? How to convert?
20Mpa=200kg/cm^2 The weight of the cylinder with a cross-sectional area of 1 square centimeter can be lifted is 200kg, so F=200X3.14X (125/2) ^2 =24531kg =24.5 tons.
