large cylinder are widely used in Poland，because of long service life，smooth movement，high work efficiency.So our company has designed large cylinder for customers from Poland.
When the large cylinder wear is serious, you can try to use an alloy scraper to shave grooves with a depth of more than 1mm on the surface of the slip injury, then clean the grooves with acetone, apply the adjusted TS311 anti-wear repair agent on the polished surface with the large cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the large cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the large cylinder can meet the requirements by grinding. However, the life and reliability of this repair large cylinder are not high.
When installing the large cylinder pipe, the pipe should be cleaned after installation, and should not pass through the large cylinder block, and the by-pass pipe must be installed in front of the oil port of the large cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the large cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the large cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.
In use, the large cylinder should try to avoid the friction iron powder or iron filings formed by buffering the plunger. When the matching gap of the buffer device is small and the transverse load on the piston rod is large, the sintering phenomenon may be caused. These friction iron powder or the metal fragments that have fallen off as a result of sintering will remain in the large cylinder.
The piston rod and guide sleeve function of the large cylinder is crucial: the relative motion pair between the piston rod and the guide sleeve is the main factor causing external leakage, if the chrome layer on the surface of the piston rod is spalling or producing longitudinal tensile marks due to wear, it will directly lead to the failure of the seal.
Why does the hydraulic cylinder go up to the top and then slowly go down?
Leakage in the cylinder or the hydraulic valve that controls the cylinder, can be replaced and removed. Or add a pressure retaining valve to the hydraulic system to ensure pressure.
How to calculate the tonnage of hydraulic cylinder? The tonnage of the cylinder refers to the output force of the cylinder under rated working pressure: 1, for single rod piston hydraulic cylinder, it can be calculated by the area of the circle corresponding to the inner diameter of the cylinder A (square centimeter), and the rated working pressure of the system p (mpa), the value is equal to 10pA kg force, and the ton is 0.01pA. 2, for the double rod piston hydraulic cylinder, with A(square centimeter) to indicate the cylinder cylinder diameter and piston rod outer diameter defined by the ring area, with p (mpa) to indicate the rated working pressure of the system, the output force of the cylinder is 0.01pA ton force.
