Sudan hydraulic cylinder,pile driver hydraulic cylinder manufacturer,pile driver hydraulic cylinder(Sudan pile driver hydraulic cylinder,produced by Hengyu Group)
pile driver hydraulic cylinder are widely used in Sudan,because of clever hydraulic energy conversion,simple structure and reliable operation,excellent temperature resistance.So our company has designed pile driver hydraulic cylinder for customers from Sudan.
At the rated pressure, the thrust of the pile driver hydraulic cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the pile driver hydraulic cylinder is related to the diameter of the pile driver hydraulic cylinder, but not to the stroke of the pile driver hydraulic cylinder. Moreover, the larger the pile driver 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 pile driver hydraulic cylinder.
If the pile driver hydraulic cylinder piston rod is found to be worn, it can be brushed and plated first, then ground, and finally adjust the mating accuracy of the piston rod and the guide sleeve. At this time, the guide sleeve can be properly redrilled or the guide sleeve can be re-turned. When making the above repairs, remember to replace various rubber seals in time.
When installing the pile driver hydraulic cylinder, the axial ends of the pile driver hydraulic cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the pile driver hydraulic cylinder, there is axial expansion. If the two ends of the pile driver hydraulic cylinder are fixed, all parts of the pile driver hydraulic cylinder will be deformed. When disassembling the pile driver hydraulic cylinder, it is strictly forbidden to hammer the pile driver hydraulic cylinder and the piston surface, such as the pile driver 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.
The coordination of the sliding parts of the pile driver hydraulic cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.
What valve is used to control cylinder expansion?
Mainly use reversing valve, but the details of the control need hydraulic control valve, hydraulic control valve can be divided into direction control valve, pressure control valve, flow control valve. The valve controls the expansion of the cylinder is the direction control valve, that is, the reversing valve. What is the meaning of two-position three-way and three-position four-way of the reversing valve? Usually according to the different working positions that can stay after the spool is moved, it can be divided into: two-position valves, three-position valves and multi-position valves. According to the number of different slide valve channels can be divided into: two-way valve, three-way valve, four-way valve, five-way valve and multi-way valve. The name of the reversing valve is called the multi-position and multi-pass reversing valve according to its working position and the number of channels.
How to take out the diaphragm of hydraulic cylinder? The septum ring is also known as the septum sleeve, when the cylinder is too long, and does not need too much travel, add the septum sleeve, limit the stroke of the hydraulic cylinder, set on the piston rod, only contact with the guide sleeve and piston, do not cooperate with the cylinder, limit the stroke, take out the difficulty is different, need to have such a professional tool, before taking out to consult the manufacturer.
