Bulgaria synchronous hydraulic cylinder

(Bulgaria synchronous hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory)

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

Introduction to synchronous hydraulic cylinder:

synchronous hydraulic cylinder piston rod material selection and technical requirements: (I), because there is no special requirements, so use 45 steel as the piston rod material, the design of the piston rod only withstand pressure stress, so no modulation processing; (ii) The coaxial tolerance of the shaft journal and the outer circle of the mounting piston is not greater than 0.01mm, so as to ensure the coaxial degree of the outer circle of the piston rod and the outer circle of the piston, and avoid the stuck phenomenon of the piston and the synchronous hydraulic cylinder, the piston rod and the guide. The vertical tolerance between the end face of the mounting piston and the axis of the piston rod is not more than 0.04mm/100mm to ensure that the piston installation does not produce skew; (iii) The outer circle of the piston rod should pay attention to the roughness; (iv) Because it is operated under low load conditions, surface treatment is omitted.

The synchronous hydraulic cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the synchronous hydraulic cylinder, bite. Elimination method: When installing the synchronous hydraulic cylinder, ensure that the axis position of the synchronous hydraulic cylinder is consistent with the direction of movement; Make the load borne by the synchronous hydraulic cylinder as far as possible through the synchronous hydraulic cylinder axis, to avoid the phenomenon of eccentricity.

If the seal of the synchronous hydraulic cylinder is softened and sticky, it may be that the seal is incompatible with the hydraulic oil or the nearby lubricating oil, replace the appropriate seal; If the seal becomes hard and loses elasticity, most of it is because the ambient temperature is too high (more than 80 ° C), make appropriate temperature insulation protection or replace the high temperature seal.

Improve the service life of the synchronous hydraulic cylinder: it is necessary to maintain the normal clearance of the combined surface of the hydraulic components. When manufacturing or repairing the main parts of the synchronous hydraulic cylinder (such as the synchronous hydraulic cylinder block, piston rod, etc.), the assembly should be carried out in accordance with the tolerance lower limit of the assembly size, which can well reduce the occurrence of cavitation. If cavitation has occurred in the hydraulic components, only metallographic sandpaper polishing technology can be used to remove cavitation pitting and surface carbon deposits, and general fine sandpaper must not be used for polishing After the synchronous hydraulic cylinder is repaired, the hydraulic system should run smoothly for a certain period of time so that the hydraulic oil in the hydraulic system can be fully circulated; If necessary, the synchronous hydraulic cylinder inlet pipe (or return pipe) can be disassembled. Make the hydraulic oil overflow to achieve the effect of single synchronous hydraulic cylinder exhaust.

Answers to some questions about synchronous hydraulic cylinder:

When there is only one hole in the oil inlet and outlet of the hydraulic cylinder, will there be oil leakage?
It is a single acting oil cylinder. This oil cylinder is always driven by hydraulic oil in advance, and is generally pulled back by the spring at the bottom of the piston or the weight of the cylinder piston or the load. But either way, it has nothing to do with any internal leakage. Whether the oil is internally drained is related to the sealing and accuracy of the cylinder itself.

How big is the pump and motor for 20 tons of hydraulic cylinder?
According to the working pressure of 25 mpa estimate, the cylinder should use 100mm bore, 63mm piston rod, stroke 40mm. According to 30 reciprocating calculation, the flow rate is about 25 liters/minute. The motor power is 11 kW, want to be cheap, use 25SCY14-1B oil pump can be.
