(Slovenia sanitation truck hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）
sanitation truck hydraulic cylinder are widely used in Slovenia，because of no need for deceleration device，long service life，smooth movement.So our company has designed sanitation truck hydraulic cylinder for customers from Slovenia.
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.
When the sanitation truck hydraulic cylinder needs to be stored for a period of time, please follow the recommended methods: The sanitation truck hydraulic cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the sanitation truck hydraulic cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil sanitation truck hydraulic cylinder should not be in direct contact with water vapor for a long time. The sanitation truck hydraulic cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the sanitation truck hydraulic cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the sanitation truck hydraulic cylinder Before working, the sanitation truck hydraulic cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the sanitation truck hydraulic cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.
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.
Do not regularly check the damage of the chrome layer of the sanitation truck hydraulic cylinder: completely extend the sanitation truck hydraulic cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the sanitation truck hydraulic cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the sanitation truck hydraulic cylinder seal. Welding slag is strictly prohibited on the surface of the sanitation truck hydraulic cylinder.
How to calculate the tonnage of the hydraulic press without konowing the diameter of the cylinder?
To know the tonnage of the hydraulic cylinder, you first need to know the working pressure of the hydraulic system, the inner diameter of the hydraulic cylinder and the outer diameter of the cylinder rod (the outer diameter of the cylinder rod is needed when calculating the hydraulic cylinder tension). The thrust of the hydraulic cylinder (that is, the force that the hydraulic cylinder can produce by extending out) = the cross-sectional area of the hydraulic cylinder (or the cross-sectional area of the piston) × the working pressure of the cylinder (the cross-sectional area of the piston) =pi*D^2/4= PI (take 3.14) × the square of the cross-sectional area of the piston ÷4 working pressure to see the pressure displayed on the pressure gauge when the maximum load is working.
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.
