Nigeria hydraulic cylinder,track steering cylinder manufacturer,track steering cylinder(Nigeria track steering cylinder,produced by Hebei Hengyu company)
track steering cylinder are widely used in Nigeria,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 Nigeria.
When the track steering cylinder needs to be stored for a period of time, please follow the recommended methods: The track steering cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the track 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 track steering cylinder should not be in direct contact with water vapor for a long time. The track steering cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the track 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 track steering cylinder Before working, the track steering cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the track 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.
track steering cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the track steering cylinder head itself is the guide sleeve of the piston rod, the track steering cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the track steering cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.
When the track steering 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 track steering cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the track steering cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the track steering cylinder can meet the requirements by grinding. However, the life and reliability of this repair track steering cylinder are not high.
The main role of the track steering cylinder: the track 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 track steering cylinder realizes reciprocating motion. The structure of the track steering cylinder has three categories: piston track steering cylinder, plunger track steering cylinder, swing track steering cylinder, piston track steering cylinder and plunger track steering cylinder to achieve reciprocating linear motion, output speed and thrust, swing track steering cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the track steering cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The track steering cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.
What is the cause of the deep scratch of the cylinder?
The following reasons can cause the cylinder to be scratched. 1: Hydraulic oil containing particulate impurities into the hydraulic cylinder, these particulate impurities stuck between the piston rod and the guide ring (or stuck between the piston and the inner wall of the cylinder), when the piston movement in the cylinder will scratch the piston rod, the phenomenon of the inner wall of the cylinder, the more particles, the larger the scratch marks the deeper and more obvious. 2: The body of the cylinder itself. Due to assembly or design reasons, the coaxial error between the piston rod, piston, cylinder, guide ring and other parts is too large, or the cylinder, piston rod straightness error is too large, so that the piston rod and the guide ring interference between the cylinder, this mechanical interference will certainly lose the piston rod or cylinder wall.
For a cylinder with a piston diameter of 100mm and a system pressure of 10MPa, what is the thrust?
Thrust is 7850 kg. Piston area A= πR^2=7850 square mm =78.5 square cm 10MPa = 100kg/cm^2 "^2" is square F = A x P =78.5 x 100=7850 kg.
