(Latvia sanitation truck hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）

sanitation truck hydraulic cylinder are widely used in Latvia，because of no need for deceleration device，long service life，smooth movement.So our company has designed sanitation truck hydraulic cylinder for customers from Latvia.

Introduction to sanitation truck hydraulic cylinder:

sanitation truck hydraulic cylinder is the most important part of construction machinery, the traditional processing method is: broaching sanitation truck hydraulic cylinder block - fine boring sanitation truck hydraulic cylinder block - grinding sanitation truck hydraulic cylinder block. The rolling method is: broaching sanitation truck hydraulic cylinder block - fine boring sanitation truck hydraulic cylinder block - rolling sanitation truck hydraulic cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the sanitation truck hydraulic cylinder block is about 1-2 days, rolling 1 meter of the sanitation truck hydraulic 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 sanitation truck hydraulic cylinder increases by 25%. If the sanitation truck hydraulic 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 sanitation truck hydraulic cylinders, you must take the rolling production process. After the sanitation truck hydraulic 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.

The piston rod of the sanitation truck hydraulic 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.

Under normal circumstances, the sanitation truck hydraulic cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the sanitation truck hydraulic cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the sanitation truck hydraulic cylinder and the end cover, the piston and the piston rod, the piston and the sanitation truck hydraulic cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the sanitation truck hydraulic cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

Repair method of small range wear of oil sanitation truck hydraulic cylinder: 1. Use oxygen-acetylene flame to bake the scratched part (master the temperature, avoid surface annealing), bake the oil on the metal surface all the year round until no sparks splash; 2. The scratched part is treated with an Angle grinder, the grinding depth is more than 1 mm, and the groove is polished along the guide rail, preferably a dovetail groove. Scratch both ends of the drilling deeper, change the force situation; 3. Clean the surface with absorbent cotton dipped in acetone or anhydrous ethanol.

Answers to some questions about sanitation truck hydraulic 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.

How many tons is the oil cylinder 16mpa?
It depends on the cross-sectional area of the cylinder A(mm2)F=16mpa×A unit is (tons).
