Qatar hydraulic cylinder,series synchronous cylinder manufacturer,series synchronous cylinder

(Qatar series synchronous cylinder,produced by Hengyu Hydraulic Co., Ltd）

series synchronous cylinder are widely used in Qatar，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed series synchronous cylinder for customers from Qatar.

Introduction to series synchronous cylinder:

The scar on the sliding surface of the series synchronous cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the series synchronous cylinder wall. Therefore, before installation, these scars must be fully repaired.

series synchronous cylinder piston rod material selection and technical requirements: (I), because there is no special requirements, so use 45 steel as the piston rod material, the design of the piston rod only withstand pressure stress, so no modulation processing; (ii) The coaxial tolerance of the shaft journal and the outer circle of the mounting piston is not greater than 0.01mm, so as to ensure the coaxial degree of the outer circle of the piston rod and the outer circle of the piston, and avoid the stuck phenomenon of the piston and the series synchronous cylinder, the piston rod and the guide. The vertical tolerance between the end face of the mounting piston and the axis of the piston rod is not more than 0.04mm/100mm to ensure that the piston installation does not produce skew; (iii) The outer circle of the piston rod should pay attention to the roughness; (iv) Because it is operated under low load conditions, surface treatment is omitted.

series synchronous cylinder piston rod material selection and requirements: ① piston rod is usually made of 45 steel. When there is a large impact force and heavy load transmission, it is made of 40Cr steel. This is to ensure that the piston rod has sufficient working strength. The piston rod is generally designed as a series synchronous cylinder, if the diameter is larger, the hollow piston rod can be used. Made of No. 45 seamless steel pipe. ③ When the piston rod is manufactured, the blank should be first forged and conditioned after mechanical rough processing, and the hardness of HB=230 ~ 250. The purpose of conditioning is to improve the machining performance and increase the working strength of the material. ④ The surface roughness Ra of the piston rod after finishing should not be greater than 0.65μm. ⑤ In order to improve the corrosion resistance of the piston rod, the working surface of the rod can be plated with hard chromium. ⑥ The piston rod and the end cap are guided by H8 ' series synchronous cylinder piston rod industry standard: piston rod diameter series of national recommended standard GB/T2348-1993. Piston rod thread size series standard GB/T2350-1980. Please refer to execute. There is no industry standard for piston rods Both the series synchronous cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The series synchronous cylinder mainly outputs linear motion and force. The series synchronous cylinder has a variety of forms, according to the different characteristics of its mechanism it can be divided into piston type, plunger type and swing type three categories, according to the mode of action he can be divided into single action and double action. Piston series synchronous cylinder, plunger series synchronous cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger series synchronous cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.

How to repair the series synchronous cylinder body when it is damaged: When the series synchronous cylinder has trace deformation and shallow tensile marks, the series synchronous cylinder is repaired by strong honing process. The heavy honing process can repair series synchronous cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the series synchronous cylinder can meet the technical requirements.

Answers to some questions about series synchronous cylinder:

How to calculate hydraulic cylinder thrust?
Cylinder diameter = piston diameter =200MM Piston area =π (200/2) square =3140 square mm =31.4 square cm 25MPA=250KG/ square cm Maximum thrust = pressure * Piston area =250 *31.4 =7850KG=78500 Newtons This is the maximum thrust. The formula can be derived from the calculation formula.

How many kilograms can the 63 cylinder hold?
The force of the cylinder is related to the cylinder diameter and pressure. 63 cylinder diameter (cylinder inner circle diameter), 21MPA pressure, thrust 6 tons.
