(Dominica steering cylinder,produced by Hebei Hengyu company）

steering cylinder are widely used in Dominica，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed steering cylinder for customers from Dominica.

Introduction to steering cylinder:

The steering cylinder is mainly composed of body, piston, piston rod, steering cylinder head, steering cylinder bottom, piston rod head and related auxiliary devices. The piston divides the steering cylinder into two chambers, and moves reciprocally in the 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 steering cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the 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 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 steering cylinder bottom and the steering cylinder head is serious, so the buffer deceleration should be set at both ends of the steering cylinder The working medium of the steering cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; 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 steering cylinder: The buffer structure of the steering cylinder is to prevent the piston from colliding with the steering cylinder head at the end of the stroke.

When the steering cylinder is in use, once the seal and guide support ring are found to be defective, the seal with the same structural form and appropriate material should be replaced according to the structural form of the steering cylinder seal to be repaired, so as to minimize the thickness of the oil film between the seal and the sealing surface and reduce the leakage of the seal.

When the steering cylinder needs to be stored for a period of time, please follow the recommended methods: The steering cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the steering cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil steering cylinder should not be in direct contact with water vapor for a long time. The steering cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the steering cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the steering cylinder Before working, the steering cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the steering cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

When the steering cylinder is kept, do not pay attention to keeping the oil port open, which will produce the condition of accepting foreign bodies at all times, which is absolutely not allowed. Storage must be filled with anti-rust oil or working oil, and plug.

Answers to some questions about steering cylinder:

What is the difference between hydraulic cylinder self-adjusting buffer and adjustable buffer?
If it is the buffer device inside the cylinder, then there are 4 basic forms, cylindrical buffer device, conical buffer device, variable throttle and adjustable flow groove. The biggest difference between the first three and the latter is that the latter can be adjusted through the external thimble to change the buffer strength, the first three mainly rely on the buffer device and buffer groove form to achieve the buffer (among them, the first type of buffer strength will not change, and the buffer strength of the two and three forms of buffer devices can be gradually increased).

Why does the hydraulic cylinder ring?
1 Air intrusion into the hydraulic system is the main reason for noise 2 The relief valve is unstable, such as due to the improper combination of the slide valve and the valve hole or the contact of the cone valve and the seat is stuck by dirt, the damping hole is blocked, the spring is crooked or fails to make the spool stuck or move in the valve hole, causing system pressure fluctuation and noise. 3 Improper adjustment of the reversing valve causes the spool of the reversing valve to move too fast, resulting in reversing impact, resulting in noise and vibration. 4 Mechanical vibration, such as long tubing, elbow more and not fixed, when the oil flow through, especially when the flow rate is high, easy to cause pipe shaking; The rotating part of the motor and hydraulic pump is unbalanced, or the alignment is not good during installation, or the coupling is loose, etc., which can produce vibration and noise.
