(Congo steering power cylinder,produced by Hebei Hengyu company）

steering power cylinder are widely used in Congo，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed steering power cylinder for customers from Congo.

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.

The "O" ring can be used as an auxiliary seal inside the steering power cylinder, and the elastic force of the "O" ring makes the sealing slip ring close to the sealing surface, generating sealing pressure to achieve sealing. When the internal hydraulic pressure increases, the "O" ring will further deform and squeeze the slip ring, thereby increasing the sealing pressure and improving the sealing performance. The structure has the characteristics of low friction coefficient, good wear resistance, automatic compensation for wear and absorption of hard particles in the steering power cylinder, and can be completely sealed.

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.

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.

Answers to some questions about steering power cylinder:

What does cylinder speed ratio mean?
The speed ratio of the cylinder is the ratio of the reciprocating speed of the piston, equal to the ratio of the rodless cavity area to the roded cavity area.

How to achieve hydraulic cylinder self-locking?
Hydraulic cylinder self-locking is divided into oil self-locking and mechanical self-locking. The oil self-locking is equipped with a valve to maintain pressure, so that the hydraulic oil of the cylinder does not return to the tank, and the oil chamber of the cylinder is filled with a certain pressure of oil. However, this pressure holding self-locking is not very safe and reliable, and the plunger will slowly return if there is a leak. Mechanical self-locking is to install a nut on the plunger of the cylinder, and when the cylinder rises to the required position, the nut on the cylinder plunger is rotated to the end, and the cylinder block is in contact, so that the plunger will be fixed to the required height. When it is necessary to relieve the pressure, screw the nut on again and let the plunger return to the position. This kind of cylinder has a special name, called self-locking hydraulic cylinder.
