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

Introduction to track steering cylinder:

When the long-stroke track steering cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in track steering cylinder head seal damage, oil leakage, and piston sleep in the track steering cylinder. The following measures can be taken: increase the piston plan to adjust the piston outer circle and process it into a convex drum, so that the piston can self-position, improve the force situation, and reduce and avoid pulling the track steering cylinder; The piston and the piston rod are connected with a spherical joint.

The role of the track steering cylinder in the mold industry: the track steering cylinder has a variety of uses in the mold, one is that the core distance is very large, or because of the mechanism of the product, only the track steering cylinder is reasonable or more cost saving. Let the side core be extracted before opening the mold. Hot runner is mainly based on the product to decide, sometimes customers require the use of hot runner, the price is more expensive, but there are many benefits, you can save raw materials, shorten the molding cycle The track steering cylinder has an irreplaceable role in the heavy industry production process: it is mainly used in places that need to support heavy objects for a long time, and it can still support heavy objects when the oil pressure is removed, and it is safe and reliable. Can be used underwater, single action, load reversion, nut self-locking to make the load safer, especially in large projects, is easy to operate control and self-locking jack, designed with a safety pressure retaining device, built-in pressure relief valve to prevent overload, to protect the self-locking jack to facilitate safe operation. The connection of the device is connected by high pressure hose and threaded joint, which has the advantages of fast use and overcoming the shortcomings of fast traditional joint oil leakage. It is mainly used for equipment installation and toppling operation in various industries such as electric power, construction, machinery manufacturing, mining, railway bridge, shipbuilding and so on.

What kind of process is used in the track steering cylinder to make high-quality track steering cylinder products: the body is the main component of the track steering cylinder, mining single pillar, hydraulic support, gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. Body processing requirements are high, the internal surface roughness requirements are Ra0.4 ~ 0.8&um, the coaxiality, wear resistance requirements are strict. The basic feature of body is deep hole processing, which has always troubled the processing personnel. The track steering cylinder products of our company mainly use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface micro-cracks and hinder the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the body can be improved. The correct rolling process of the track steering cylinder block: broaching block - fine boring block - grinding block. The rolling method is: broaching block - fine boring block - rolling block, the process is 3 parts, but the time is compared: grinding 1 meter of the block is about 1-2 days, rolling 1 meter of the block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3um before rolling to RA0.4-0.8&um, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the track steering cylinder increases by 25%. If the service life of the track steering cylinder is only considered, it is increased by 2 to 3 times, and the efficiency of the boring and rolling process is about 3 times higher than that of the grinding process. track steering cylinder misoperation or operation failure may be caused by the following reasons, you can start from these aspects of the investigation: (1) spool stuck or valve hole blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the track steering cylinder is prone to misoperation or operation failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium. (2) The piston rod and track steering cylinder are stuck or the track steering cylinder is blocked. At this time, no matter how to manipulate, the track steering cylinder does not move or moves very little. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the track steering cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

The method of sleeve track steering cylinder to improve the processing quality: there is a big gap in the service life of post-plating polishing and post-plating polishing, especially in mass production. Strictly clean the flying edge and burr of mechanical components, especially the edge of the sealing groove, and the tiny metal burr, strictly clean before assembly. The surface fatigue strength and stress corrosion resistance of the track steering cylinder can be significantly improved by rolling in the finishing of the inner holes of the track steering cylinder. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.

Answers to some questions about track steering cylinder:

In a hydraulic system, a hydraulic pump has many hydraulic cylinders and hydraulic motors, and these executive components do not coordinate their actions with each other.
A load-sensitive variable pump can be used if these components sometimes need to work simultaneously and the power required is large. The required flow is distributed by the multi-way reversing valve, and the required flow and pressure changes are automatically adjusted by the hydraulic pump. Pressure reducing valves can be used for particularly low pressure circuits. Because you execute more components, the use of quantitative pump will cause a waste of energy, the system heat is large, not suitable.

How long can a hydraulic cylinder work continuously?
If the maintenance is good, the service life can be extended a lot. The life of the cylinder is related to the structure of the cylinder, working pressure, stress state, hydraulic oil cleanliness, oil temperature control, maintenance and preventive measures. For example, the cylinder structure, the inner wall of the cylinder has quilting, rolling, chrome plating and other methods, the sealing parts have polyurethane rings, glay rings, metal sealing rings, etc., different combinations, the life difference is dozens of times. Metallurgical system is a typical cylinder application, in 24 hours of work, a year or more can not be shut down, in the middle of continuous work.
