Angola hydraulic cylinder,synchronous hydraulic cylinder manufacturer,synchronous hydraulic cylinder(Angola synchronous hydraulic cylinder,produced by Hengyu Group)
synchronous hydraulic cylinder are widely used in Angola,because of excellent temperature resistance,powerful torque,no transmission clearance.So our company has designed synchronous hydraulic cylinder for customers from Angola.
When the synchronous hydraulic cylinder is installed, the piston and the synchronous hydraulic cylinder head and other parts have large mass, large size and large inertia, even if there is a lifting equipment auxiliary installation, because the specified clearance is small, no matter how hard it will be put into, therefore, the end of the piston or the synchronous hydraulic cylinder head boss is easy to cause scars when it hits the inner surface of the synchronous hydraulic cylinder wall. The solution to this problem: for a large number of small products, the use of autocratic assembly oriented tools during installation; For heavy, thick and large large and medium-sized synchronous hydraulic cylinders, only careful and careful operation can be avoided.
synchronous hydraulic cylinder piston rod material introduction: In general, we use 45 steel to produce synchronous hydraulic cylinder piston rod. It has a large impact force when it is used, and some good performance steel are also used in the heavy load transmission. In order to have enough work intensity when using, and can ensure normal use, this is still more critical to have a detailed understanding of the material.
In recent years, the processing process of the synchronous hydraulic cylinder generally adopts the rolling method, which is a pressure finishing processing, which uses the cold plastic characteristics of the metal at room temperature, and uses the rolling tool to exert a certain pressure on the surface of the workpiece, so that the surface metal of the workpiece produces plastic flow, and fills in the low concave trough of the original residue, and the roughness value of the workpiece surface is reduced. Due to the plastic deformation of the rolled surface metal, the surface tissue is cold hardened and the grain is fine, forming a dense fiber, and forming a residual stress layer, and the hardness and strength are increased, thus improving the wear resistance, corrosion resistance and compatibility of the workpiece surface. Rolling is a plastic machining method without cutting.
If air enters the hydraulic system, the synchronous hydraulic cylinder will not operate normally, mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced.
What is the safety factor of 25MPa cylinder wall thickness?
Safety factor n can take 3 cylinder material allowable stress [s]=sb/n δ/D=0.08 ~ 0.3 cylinder wall thickness δ=PMAX*D/ (2.3[s]-3PMAX) δ/D≤0.08 cylinder wall thickness δ=PMAX*D/2[s] P < 16MPa, Pmax=1.5Pn; P > 16MPa, Pmax=1.25Pn cold-drawn tube or honing tube is better!
How to calculate multistage cylinder volume?
When the multi-stage cylinder is extended, the largest cylinder is extended first, and when the largest cylinder stroke is completed, the second largest cylinder is extended again, the second largest cylinder stroke is completed, the third largest cylinder is extended again... Therefore, the cylinder extension length is less than the stroke of the largest cylinder, and the volume is the extension length times the inner hole area of the largest cylinder. The cylinder extension length is greater than the maximum cylinder stroke and less than (the largest cylinder stroke + the second largest cylinder stroke), and the volume is the largest cylinder stroke times the internal hole area of the largest cylinder + (the extension length - the largest cylinder stroke) times the second largest cylinder.
