track steering cylinder are widely used in Spain，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed track steering cylinder for customers from Spain.

Introduction to track steering cylinder:

When installing the track steering cylinder pipe, the pipe should be cleaned after installation, and should not pass through the track steering cylinder block, and the by-pass pipe must be installed in front of the oil port of the track steering cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the track steering cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the track 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.

track steering cylinder and hydraulic station selection: Select the type and structure of the track steering cylinder according to the operation requirements of the main engine. According to the external load force borne by the track steering cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the track steering cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the track steering cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the track steering cylinder, the diameter of the piston and the piston rod.

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

The piston seal of the track steering cylinder is the main element to prevent leakage in the track steering cylinder. For the lip seal, it should focus on checking whether the lip edge is bruised and worn, and for the combination seal, it should focus on checking the wear of the sealing surface, and then determine whether the seal can be used. In addition, it is necessary to check whether the static seal between the piston and the piston rod is crushed. The piston rod seal should focus on checking the wear of the seals and supporting rings.

Answers to some questions about track steering cylinder:

What hydraulic valve is used to control a cylinder back and forth?
Direction valve is available. Direction valve includes electromagnetic directional valve, manual directional valve, check valve, hydraulic control check valve, the specific choice of which direction valve, you need to see the use of conditions.

What are the reasons why the hydraulic cylinder action is slower than normal?
There are many factors that cause this problem. First, measure the pressure of the main system to see whether the pressure of the main system under the pressure state is consistent with the initial setting. Before measuring the pressure, it is best to check the hydraulic oil and suction oil filter and replace or clean it. Second, check the main relief valve of the reversing control multiway valve to see if there is damage or foreign matter blocking, and clean it. If your pump is a gear pump, the problem should generally be small. Second, look at traffic. There is no leakage in the cylinder, leakage in the reversing valve spool and so on.
