Azerbaijan large cylinder

(Azerbaijan large cylinder,produced by Hebei Hengyu company)

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

Introduction to large cylinder:

large cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the large cylinder head itself is the guide sleeve of the piston rod, the large cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the large cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

If the piston rod and large cylinder are stuck or the large cylinder is blocked, at this time, no matter how to operate, the large cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the large cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

Regular maintenance of the large cylinder includes: regular tightening, large cylinder fastening screws and gland screws, large cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the large cylinder once a year. Clean regularly, the large cylinder is cleaned every other year, and the seals are replaced while cleaning.

large cylinder is the most important part of construction machinery, the traditional processing method is: broaching large cylinder block - fine boring large cylinder block - grinding large cylinder block. The rolling method is: broaching large cylinder block - fine boring large cylinder block - rolling large cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the large cylinder block is about 1-2 days, rolling 1 meter of the large cylinder block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3 μm before rolling to Ra0.4 ~ 0.8μm, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the large cylinder increases by 25%. If the large cylinder life is only considered, it is increased by 2 to 3 times, and the boring and rolling process is 3 times more efficient than the grinding process In particular, if you want to make high-quality large cylinders, you must take the rolling production process. After the large cylinder is rolled, there is no sharp tiny edge on the surface, and long-term motion friction will not damage the seal ring or seal, which is particularly important in the hydraulic industry.

Answers to some questions about large cylinder:

How many tons can a 10mpa cylinder with a diameter of 100 hold up?
About 8 tons. Algorithm: Cylinder cross-sectional area = π* (100/2) ^2=3.14*2500=7850 square mm = 0.00785 square meters pressure = pressure * Cross-sectional area = 10000000Pa*0.00785 square meters = 78500 n mass = pressure /g = 78500 N ÷9.8 n/kg = 8010 kg = 8.01 Tons.

What factors does the movement speed of the cylinder in the hydraulic system depend on?
The hydraulic system should be the piston movement in the cylinder, and the speed should also be the speed of the piston, according to the piston speed formula: v=4qm/pai*(D^2-d^2) where q is the flow rate of the input hydraulic cylinder, m is the volumetric efficiency of the hydraulic cylinder, D, d is the diameter of the piston and piston rod, because other factors are determined, the movement speed of the cylinder depends on the flow rate.
