Hydraulic Brake Shear oil cylinder, also known as a hydraulic cylinder, is an important part of hydraulic metal sheet cutting equipment.
Hydraulic Guillotine Brake Shears
Shearing machine is a kind of forging machine. It is widely used in aviation, light industry, metallurgy, chemical industry, construction, shipping, automobile, electric power, electrical appliances, decoration and so on.
Cylinder in hydraulic metal shears
Hydraulic cylinder is the most important element to implement energy conversion and oil transfer in the shearing machinery. The abnormal operation of the cylinder will cause instability of the shearing machine system.
In order to ensure the normal operation of shears, we should find out the cause of the fault as soon as possible and repair it in time. Next, professional shearing machine supplier Wuxi Shearchy explains the way to solve the hydraulic cylinder failure of plate shears.
Hydraulic Plate Shearing Machine Cylinder Troubleshooting
Problem 1: insufficient oil supply for the shear machines’ hydraulic pump
It is because of wear on the inside parts of hydraulic pump, which increases the cylinder load. That results in an increase in pressure as well as internal leakage. The increase of leakage will cause the pump to transport cylinders at a speed not up to the required value.
Problem 2: incorrect connection between hydraulic cylinder & hydraulic brake shear load
When the connection of the load is not correct, it can cause the cylinder to move at a slower rate. And then, it will cause the hydraulic cylinder to operate abnormally.
Problem 3: layout of hydraulic cylinder has some problems
The piston end face is close to the cylinder end face. At start-up, the piston capacity area is insufficient, so it cannot drive the load. As a result, the speed of the cylinder slows down when it moves.
Problem 4: problems with flow valve
If the valve core of the overflow valve is stuck in the open position, a large amount of fluid flows from the overflow valve back to the tank. So it makes an increase in the flow into the cylinder and cause slow.
Small accumulator volume or low inflatable pressure is also a primary cause of abnormal work of the oil cylinder of sheet metal shearing machines. Therefore, when using hydraulic brake shear, the user should observe the machine working conditions, including the pressure, speed, fluid leakage, vibration, etc.
