(S.Africa servo hydraulic cylinder,produced by Hebei Hengyu company）

servo hydraulic cylinder are widely used in S.Africa，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed servo hydraulic cylinder for customers from S.Africa.

Introduction to servo hydraulic cylinder:

The quality of the servo hydraulic cylinder can not be ignored in the purchase of the servo hydraulic cylinder. The servo hydraulic cylinder is the main component of the servo 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. servo 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 servo hydraulic cylinder is deep hole processing, which has always troubled the processing personnel.

In order to ensure the service life of the servo hydraulic cylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the servo hydraulic cylinder, causing damage to the seal and causing leakage in the servo hydraulic cylinder. It is required that the filtration accuracy of the system is not less than 80μm, the oil pollution is strictly controlled, the hydraulic oil is kept clean, the performance of the hydraulic oil is regularly checked, and the necessary fine filtration or replacement of the new working hydraulic oil is carried out.

At the rated pressure, the thrust of the servo hydraulic cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the servo hydraulic cylinder is related to the diameter of the servo hydraulic cylinder, but not to the stroke of the servo hydraulic cylinder. Moreover, the larger the servo hydraulic cylinder diameter, the larger the area, and the greater the pressure obtained. To this point, we should have a correct understanding and clear understanding, so as to avoid problems in the use of the servo hydraulic cylinder.

When the servo hydraulic cylinder is repaired, its inner and outer diameter and roundness should be accurately measured. If the inner hole of the servo hydraulic cylinder is badly worn, it can be repaired by grinding the mandrel or honing on the boring machine. If the piston is worn, it can be repaired by electroplating, and serious wear should be replaced.

Answers to some questions about servo hydraulic cylinder:

How to calculate cylinder speed?
If there is a throttle valve, the cylinder speed will be adjustable. When the throttle is fully opened, the speed of the cylinder reaches the maximum: maximum speed = oil pump displacement ÷ cylinder cavity cross-sectional area The displacement of the oil pump is a main indicator, which can be found on the nameplate, and some can also be known by the oil pump model; The cross-sectional area of the cylinder cavity can be easily calculated. Just make sure the units are the same. And because the cross-sectional area of the rod cavity and the rodless cavity of the cylinder is different, the speed of advance and retreat may also be different.

Does the sealing string of the upper and lower chamber of the hydraulic cylinder fall by itself?
It is possible, the probability accounts for 85% (depending on the weight), the weight is less than the system resistance, may not fall, the weight is greater than the system resistance, will not necessarily fall, so often check the equipment, safety first, find the problem in time to solve, the cylinder is not very expensive parts, maintenance does not cost much money, However, accidents caused by cylinder failure will lose several times the cost.
