Jordan hydraulic cylinder,steering cylinder manufacturer,steering cylinder

(Jordan steering cylinder,produced by Hebei Hengyu company）

steering cylinder are widely used in Jordan，because of no need for deceleration device，high work efficiency，excellent fatigue and impact resistance.So our company has designed steering cylinder for customers from Jordan.

Introduction to steering cylinder:

The machining accuracy of the steering cylinder depends on the level of equipment, production technology and testing means. steering cylinder processing methods are commonly used in two ways, one is rough boring - fine boring - rolling, generally with 45# seamless steel pipe, this method of processing quality is good, but the cost is high. Another method is to use 20# cold-drawn seamless steel pipe, and then honing, the cost is lower. The piston rod must be adjusted and straightened before processing, and the coating thickness of the piston rod is generally not less than 0.03mm. The piston must be machined in strict accordance with the groove size and tolerance requirements given in the seal manual.

steering cylinder installation precautions: Before installing the steering cylinder into the system, the parameters on the steering cylinder label should be compared with the parameters when ordering. The base of the steering cylinder must have sufficient stiffness, otherwise the steering cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.

When installing the steering cylinder pipe, the pipe should be cleaned after installation, and should not pass through the steering cylinder block, and the by-pass pipe must be installed in front of the oil port of the steering cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the steering cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the steering cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.

steering 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 steering 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 ' steering 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 steering cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The steering cylinder mainly outputs linear motion and force. The steering 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 steering cylinder, plunger steering cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger steering cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.

Answers to some questions about steering cylinder:

How to disassemble the cylinder?
Generally speaking, it is not difficult to disassemble the hydraulic cylinder, as long as you are careful, but you often encounter some small trouble in the disassembly process, because the disassembly process is not correct. In fact, this can be avoided, as long as you follow below points. 1. Before removing the hydraulic cylinder, the hydraulic circuit should be relieved of pressure, otherwise, when the oil pipe connected with the cylinder is loosened, the high-pressure oil in the circuit will be rapidly ejected. When the hydraulic pressure comes back, the handwheel or pressure regulating screw at the relief valve should be loosened first, so that the pressure oil is unloaded, and then the power supply or power source is cut off, so that the hydraulic device stops running. 2. Disassembly should prevent damage to the top thread of the piston rod, the oil thread and the chrome layer on the piston rod surface.

What is the cause of sound and vibration when the hydraulic cylinder is under load?
The main reason 1) may be that the load machinery has stuck phenomenon, and the resistance is large. 2) The hydraulic oil is not enough, or the filter is blocked by dirty things, and the oil is flooded. 3) There is a problem with the pump.
