synchronous hydraulic cylinder are widely used in Holland，because of long service life，smooth movement，high work efficiency.So our company has designed synchronous hydraulic cylinder for customers from Holland.

Introduction to synchronous hydraulic cylinder:

synchronous hydraulic cylinder body inspection: The inner surface of the synchronous hydraulic cylinder and the piston seal are the main factors causing the leakage in the synchronous hydraulic cylinder, if the synchronous hydraulic cylinder has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the synchronous hydraulic cylinder mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.

The synchronous hydraulic cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure synchronous hydraulic cylinder can use 20 steel pipe, and the high pressure synchronous hydraulic cylinder can use 45 steel pipe.

When installing the synchronous hydraulic cylinder, the axial ends of the synchronous hydraulic cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the synchronous hydraulic cylinder, there is axial expansion. If the two ends of the synchronous hydraulic cylinder are fixed, all parts of the synchronous hydraulic cylinder will be deformed. When disassembling the synchronous hydraulic cylinder, it is strictly forbidden to hammer the synchronous hydraulic cylinder and the piston surface, such as the synchronous hydraulic 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.

Factors that should be considered when selecting the oil seal in the synchronous hydraulic cylinder: some specific factors should be taken into account when selecting the oil seal in the synchronous hydraulic cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: synchronous hydraulic cylinder diameter, piston rod diameter, piston rod and piston groove size, synchronous hydraulic cylinder working pressure, synchronous hydraulic cylinder movement speed, hydraulic system oil temperature and synchronous hydraulic cylinder working environment.

Answers to some questions about synchronous hydraulic cylinder:

Why are the hydraulic cylinders out of sync? The reasons for the unsynchronous operation are as follows: 1, the deviation of the external load of the two cylinders, such as the different resistance and friction of the two cylinders will lead to imbalance. The displacement of the cylinder with low resistance will be larger. 2, the difference in internal friction, such as the difference between the piston and the cylinder of each cylinder, the friction between the piston rod and the seal causes the cylinder to be out of sync. 3. The different resistance of hydraulic oil along the pipeline of the two cylinders causes the cylinder to be out of sync. 4, the deviation of the control original adjustment causes the deviation of the flow to be out of sync, such as the use of an independent throttle valve for each cylinder will appear the difference in the flow of oil in and out of the oil affecting the synchronization of the two cylinders. 5. The cylinder support point of the supported part is initially different.

What is the relationship between medium cylinder and side cylinder ratio of forklift truck?
The middle cylinder and the side cylinder seem to have no relationship, as long as the lifting speed required by the design can be ensured, but the diameter of the cylinder can not be too thin, so as to avoid the middle cylinder acting first when the high gantry vibration lifting, and then the two cylinders acting again.
