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

steering power cylinder are widely used in Italy，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed steering power cylinder for customers from Italy.

Introduction to steering power cylinder:

When the steering power cylinder wear is serious, you can try to use an alloy scraper to shave grooves with a depth of more than 1mm on the surface of the slip injury, then clean the grooves with acetone, apply the adjusted TS311 anti-wear repair agent on the polished surface with the steering power cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the steering power cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the steering power cylinder can meet the requirements by grinding. However, the life and reliability of this repair steering power cylinder are not high.

How to determine the working pressure of the steering power cylinder: The pressure depends on the load size (i.e., F) and the type of equipment. The limitations of assembly space, economic conditions and component availability of the actuator should also be considered. In the case of a certain load, it is necessary to increase the structural size of the actuator if the working pressure is low, for some equipment, the size may be limited, and it is not economical from the point of view of material consumption; On the contrary, if the pressure selection is too high, the material, sealing and manufacturing accuracy of the pump, steering power cylinder, valve and other components are also required to be high, which will inevitably increase the cost of equipment. In general, for equipment with a fixed size that is not too limited, the pressure can be selected lower, and the walking machinery should be selected higher.

The internal leakage of the steering power cylinder is an important indicator to measure the quality of the steering power cylinder: the internal leakage of the steering power cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the steering power cylinder, so that the steering power cylinder can not accurately and stably stop in a certain position of the steering power cylinder, so it is one of the main indicators of the steering power cylinder.

When the steering power cylinder needs to be stored for a period of time, please follow the recommended methods: The steering power cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the steering power 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 power cylinder should not be in direct contact with water vapor for a long time. The steering power cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the steering power 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 power cylinder Before working, the steering power cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the steering power cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

Answers to some questions about steering power cylinder:

How to limit cylinder push rod rotation?
In general, the push-rod rotation can be limited after the push-rod is connected to the pushed mechanism. For example, the push rod is hinged with the push mechanism, or the push mechanism itself is guided, which can limit the rotation of the push rod.

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).
