(Kenya large bore cylinder,produced by Hebei Hengyu company）

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

Introduction to large bore cylinder:

When the large bore cylinder needs to be stored for a period of time, please follow the recommended methods: The large bore cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the large bore 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 large bore cylinder should not be in direct contact with water vapor for a long time. The large bore cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the large bore 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 large bore cylinder Before working, the large bore cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the large bore 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 initial action of the large bore cylinder is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the large bore cylinder. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.

In the process of using the large bore cylinder, sometimes such a problem will occur, the large bore cylinder can not act immediately after the instruction of the large bore cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil large bore cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

In the hydraulic system, sometimes the inner layer of the rubber hose is peeled off, so that the oil circuit is on and off, resulting in irregular large bore cylinder action. Troubleshooting method: Replace the rubber hose.

Answers to some questions about large bore cylinder:

How to repair the bent oil cylinder correctly?
If the bending oil cylinder leaks, the most direct way is to replace the seal ring. Most of the sealing rings used by domestic bending machines are made in Taiwan and Japan, so the service life of the sealing ring is still relatively long. If the bending oil cylinder used by the customer leaks oil, then when replacing the seal ring, be sure to choose a high-quality and durable seal ring. In this way, the replaced cylinder will not leak oil for a long time.

The diameter of the cylinder is 180mm and the pressure is 14mpa. How many tons can the cylinder hold?
Calculate the area of the cylinder, 3.14*9*9=254.34 square centimeters, take the approximate number of engineering, 1 mpa pressure is about 10 kg per square centimeter, 14 mpa pressure is 140 kg per square centimeter, that is 254.34*140=35607.6 kilograms, it can be known that the cylinder can be about 35 tons in theory.
