ã€Selectionã€‘ hydraulic cylinder
1, the hydraulic cylinder pressure can be divided in accordance with the following specifications
Low pressure hydraulic cylinder 0 ~ 3.5MPa
Low pressure hydraulic cylinder 0 ~ 7.0MPa
Medium pressure hydraulic cylinder 7.0 ~ 14.0MPa
High-pressure hydraulic cylinder 14 ~ 21.0MPa
More than 21MPa high pressure hydraulic cylinder
2, hydraulic cylinder type selection
Single-acting hydraulic cylinder is only by weight, external load or mechanical means such as spring force when used to achieve a return, most people use the double-acting cylinder.
3, the hydraulic cylinder parameters View national standard size series hydraulic cylinder
1) diameter cylinder
According to the required output force F and the set pressure of the hydraulic system and hydraulic cylinders p Î·m mechanical efficiency calculated using the relevant formula, but in the end must be selected in line with the national standard GB2348-1993 values in order to use standard products and standard seals .
Schedule depends on the load hydraulic cylinder movement distance. Travel long thick rod is required, may be even with the stopper in the cylinder casing, to improve the ability of anti-longitudinal and bending.
3) piston rod diameter
Piston rod diameter must be large enough to withstand the loads and stresses imposed by tanks. Rod by pulling the piston rod area divided by the piston force is equal to the yield limit and then multiplied by the safety factor. However, by the thrust rod must have sufficient longitudinal and bending strength. When the longitudinal bending strength is not enough and have a greater deflection, due to the sliding surface of the friction caused by the piston guide sleeve and a greater partial load, resulting in jamming, reptiles, seals, abnormal wear and other issues. Required to prevent buckling strength depends on the itinerary and the additional fulcrum connection.
4) cylinder speed
Cylinder and the cycle time to determine speed and cylinder stroke related. The speed range is generally recommended 15 ~ 300mm / s. Cylinder speed is too high will shorten the life of seals. Prone to crawling speed is too low Shihai phenomenon, can not work smoothly
5) port diameter
Port diameter d0 speed according to the cylinder and piston area identified. Port flow rate should not exceed 5m / s, so as not to affect the cylinder pressure loss is too large output force
4, cylinder head structure selection
General multi-purpose machinery and equipment and threaded rod, metallurgical machinery, forging machinery, heavy and high-pressure cylinder with a welded large diameter cylinder.

5, the hydraulic cylinder installed connection
Including the flange type, pin type, earring type, base type, ball type
See connection diagram hydraulic cylinder installation choose to install the connection to
6, the choice of the buffer device
Made after the hydraulic cylinder moving speed of the load above a certain standard, must choose a buffer device of the hydraulic cylinder. Or reach a higher speed than the hydraulic cylinder must be installed in the valve gear.
7, the sealing device of choice
Cautious in the selection of hydraulic oil and oil seal. Different hydraulic oil for the seals of different materials to protect the hydraulic cylinder life.
ã€How to choose a hydraulic cylinder manufacturersã€‘
1, the geographical characteristics of comparison:
Hydraulic cylinder manufacturers are mainly distributed in four provinces: Zhejiang, Guangdong, Suzhou, Shandong
1) to take the nearest principle 2) Zhejiang hydraulic products generally have high cost performance 3) competitive products company
2, hydraulic cylinder of the Company for material selection, except in accordance with national standards, more stringent control of processing technology. For example, size of Machining tolerances, geometric tolerances, are based on accumulated experience of many years of research and development technology and strict requirements, not sloppy. All kinds of hydraulic cylinders with low friction, high-life advantages.
3, the standard hydraulic cylinder steel tube material is carbon steel mechanical structure, mark STKM13C. After a cold drawn seamless, high-precision honing diameter after processing, the diameter tolerance of the H7 ~ H9, surface roughness in the 0.8s ~ 3s, tensile strength of 52kgf/cm square above.
4, the rod material is carbon steel mechanical structure, sign S45C, after grinding and hard outer coating Nuo, the diameter tolerance of the F7 ~ F8, the surface hardness of HV700 or more. Surface roughness in the 0.8s ~ 1.6s hard chromium thickness 20um.
5, the use of imported oil seal high refined products, oil, corrosion, wear and resistance to stress.
6, after the parts are CNC lathes, CNC milling complete precision machining, dimensional tolerances meet the JSI standards, interchangeability good, long life, easy maintenance
