(America servo cylinder,produced by Hebei Hengyu company）

servo cylinder are widely used in America，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed servo cylinder for customers from America.

Introduction to servo cylinder:

How the cavitation of the servo cylinder is formed: With the gradual rise of pressure, the gas in the oil will become bubbles, when the pressure rises to a certain limit value, these bubbles will break under the action of high pressure, so that the high temperature and high pressure gas will quickly act on the surface of the parts, resulting in cavitation of the servo cylinder, resulting in corrosive damage to the parts.

Causes and countermeasures of oil servo cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the servo cylinder will lead to premature wear of the piston seal, replace the piston seal; If the servo cylinder is visibly scarred, the servo cylinder must be replaced. It can be pressurized at one end of the servo cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most servo cylinder piston drift may not come from the servo cylinder, the above method to determine the servo cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.

Regular maintenance of the servo cylinder includes: regular tightening, servo cylinder fastening screws and gland screws, servo cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the servo cylinder once a year. Clean regularly, the servo cylinder is cleaned every other year, and the seals are replaced while cleaning.

When the initial action of the servo cylinder is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the servo cylinder. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.

Answers to some questions about servo cylinder:

How to calculate the tonnage of the hydraulic press without konowing the diameter of the cylinder?
To know the tonnage of the hydraulic cylinder, you first need to know the working pressure of the hydraulic system, the inner diameter of the hydraulic cylinder and the outer diameter of the cylinder rod (the outer diameter of the cylinder rod is needed when calculating the hydraulic cylinder tension). The thrust of the hydraulic cylinder (that is, the force that the hydraulic cylinder can produce by extending out) = the cross-sectional area of the hydraulic cylinder (or the cross-sectional area of the piston) × the working pressure of the cylinder (the cross-sectional area of the piston) =pi*D^2/4= PI (take 3.14) × the square of the cross-sectional area of the piston ÷4 working pressure to see the pressure displayed on the pressure gauge when the maximum load is working.

What is the main maintenance of the cylinder?
After disassembling the cylinder: 1, clean the cylinder and piston; 2, replace all seals; 3, if there is a valve to repair, to ensure sealing and flexible; 4, deal with all deformation parts; 5. Installation experiment.
