(Norway track steering cylinder,produced by Hebei Hengyu company）

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

Introduction to track steering cylinder:

Analysis of commonly used seals: The wear ring and slip ring commonly used on the track steering cylinder are generally made of polytetrafluoroethylene + graphite, because pure polytetrafluoroethylene is easy to produce plastic creep, which is only suitable for low pressure and low wear resistance conditions. If the sealing ring used is a composite material formed after adding graphite filler, the performance can be effectively improved, the ability to resist plastic creep is increased by 2 to 3 times, the initial deformation caused by the load is reduced by 30 to 60% : the rigidity is increased by 2 to 3 times: the dimensional stability under heat is increased by 2 times, and the hardness is increased by l0 to 15%.

The advantages and disadvantages of the track steering cylinder: the surface of the track steering cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the track steering cylinder through the top heat treatment, high manufacturing precision, belongs to the precision machinery, has a simple structure, stable quality, high mechanical efficiency, easy to achieve automation and many other advantages. However, hydraulic technology also has the shortcomings of oil leakage, oil temperature change affecting the control of running speed, noise, expensive cost and high maintenance cost.

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.

The track steering cylinder is mainly composed of body, piston, piston rod, track steering cylinder head, track steering cylinder bottom, piston rod head and related auxiliary devices. The piston divides the track steering cylinder into two chambers, and moves reciprocally in the track steering cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the track steering cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the track steering cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the track steering cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the track steering cylinder bottom and the track steering cylinder head is serious, so the buffer deceleration should be set at both ends of the track steering cylinder The working medium of the track steering cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; track steering cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the track steering cylinder: The buffer structure of the track steering cylinder is to prevent the piston from colliding with the track steering cylinder head at the end of the stroke.

Answers to some questions about track steering cylinder:

How does the clamping cylinder work?
Hydraulic transmission principle: oil as the working medium, through the change of the sealing volume to transfer movement, through the internal pressure of the oil to transfer power. 1. The power part - converts the mechanical energy of the prime mover into the pressure energy of the oil (hydraulic energy). For example: hydraulic pump. 2, The executive part - the hydraulic pump input oil pressure energy into the mechanical energy to drive the working mechanism. For example: hydraulic cylinder, hydraulic motor. 3, The control part - used to control and adjust the oil pressure, flow and flow direction. For example: pressure control valve, flow control valve and direction control valve. 4, The auxiliary part - the first three parts are connected together to form a system, which plays the role of oil storage, filtration, measurement and sealing.

How big is the pump and motor for 20 tons of hydraulic cylinder?
According to the working pressure of 25 mpa estimate, the cylinder should use 100mm bore, 63mm piston rod, stroke 40mm. According to 30 reciprocating calculation, the flow rate is about 25 liters/minute. The motor power is 11 kW, want to be cheap, use 25SCY14-1B oil pump can be.
