Bolivia tailboard balance cylinder

(Bolivia tailboard balance cylinder,produced by Hebei Hengyu company)

tailboard balance cylinder are widely used in Bolivia,because of no transmission clearance,powerful torque,clever hydraulic energy conversion.So our company has designed tailboard balance cylinder for customers from Bolivia.

Introduction to tailboard balance cylinder:

The cavitation of the tailboard balance cylinder has a great influence, and to avoid it, it is necessary to use the hydraulic oil reasonably and ensure the quality of the hydraulic oil. If the anti-foam property of the oil is poor, it is easy to produce foam, resulting in cavitation. Secondly, the change frequency of oil pressure is too fast and too high, which will also directly cause the formation of bubbles and accelerate the rupture rate of bubbles. The test shows that the speed of cavitation will be accelerated in the part with high frequency of pressure change. For example, at the inlet and outlet of the tailboard balance cylinder, due to the relatively high frequency of pressure changes, the degree of cavitation is also relatively higher than that of other parts. In addition, overheating of the oil will also increase the probability of cavitation.

The piston rod of the tailboard balance cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.

When installing the tailboard balance cylinder, the axial ends of the tailboard balance cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the tailboard balance cylinder, there is axial expansion. If the two ends of the tailboard balance cylinder are fixed, all parts of the tailboard balance cylinder will be deformed. When disassembling the tailboard balance cylinder, it is strictly forbidden to hammer the tailboard balance cylinder and the piston surface, such as the tailboard balance 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 tailboard balance cylinder: some specific factors should be taken into account when selecting the oil seal in the tailboard balance 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: tailboard balance cylinder diameter, piston rod diameter, piston rod and piston groove size, tailboard balance cylinder working pressure, tailboard balance cylinder movement speed, hydraulic system oil temperature and tailboard balance cylinder working environment.

Answers to some questions about tailboard balance cylinder:

Why is there noise in the hydraulic cylinder of the excavator lift arm?
There is no noise of a normal cylinder, check whether the throttle is ringing, or the mechanical part connected with it is ringing, and the mechanical part can be greased. If it can't be ruled out, disconnect the cylinder from the mechanical part and act alone to see what the situation is.

Hydraulic system schematic diagram, pipeline identification S and L, respectively corresponding nominal diameters? 16S is equivalent to DN12 high-pressure cylinder, and 15L means what?
16S refers to the high pressure series, outer diameter 16x2 steel pipe, the corresponding sleeve nut is M24X1.515L is the low pressure series, the outer diameter of 15x1.5 steel pipe, the corresponding sleeve nut is M22X1.5.
