(Kazakhstan steering cylinder,produced by Hengyu Hydraulic Co., Ltd）

steering cylinder are widely used in Kazakhstan，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed steering cylinder for customers from Kazakhstan.

Introduction to steering cylinder:

The daily inspection of the steering cylinder includes: checking the connection of the steering cylinder and the pipe joint for leaks. Check the steering cylinder rod for leaks. Check the steering cylinder connection for leaks. When the steering cylinder moves, the work is normal and smooth. Whether the steering cylinder has internal leakage.

The main role of the steering cylinder: the steering cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the steering cylinder realizes reciprocating motion. The structure of the steering cylinder has three categories: piston steering cylinder, plunger steering cylinder, swing steering cylinder, piston steering cylinder and plunger steering cylinder to achieve reciprocating linear motion, output speed and thrust, swing steering cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the steering cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The steering cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.

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.

When installing the piston rod, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the steering cylinder head adn the earring (or the middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent the phenomenon of rigid interference and causing unnecessary damage.

Answers to some questions about steering cylinder:

What is the reason why the hydraulic cylinder is not good at lifting?
There may be several situations 1, whether the slow one is worn 2, whether there is air in the slow cylinder 3, if the two cylinders are supplied by the same oil port, whether the slow joint is blocked (some processing residue will reach a certain oil port under a certain coincidence condition, This situation will not happen if it is not necessarily good before) 4, the oil seal in the slow cylinder leaks, causing the feed oil to leak from the return oil end. Point 4 is most likely because it is invisible and a technical failure. If it is a dual oil feed (separate oil feed), it is also necessary to check the oil supply system and the oil return system (valve type).

How to deal with hydraulic cylinder inner wall rag, local wear serious or corrosion?
It can be reparied if the inner wall of the hydraulic cylinder is frayed, local wear or corrosion. We can use the inner wall cold melting copper technology, it has the following advantages: first, the temperature is low, the operating temperature is less than 180 degrees, and the heat affected zone is small. Second: high hardness is up to Brinell hardness 280, wear resistance and anti-corrosion. Third: the process is mature, some large coal mills have been repaired with this method and the effect is remarkable.
