Ensure the hydraulic oil of WC67K-30T1200 Hydraulic Press Brake machine is clean and reduce pollution
Hydraulic oil of hydraulic bending machine should be correctly selected to prevent contamination and impurities from entering the hydraulic oil of hydraulic bending machine. The hydraulic oil of hydraulic bending machine is not only the medium of hydraulic system, but also the lubricant, so it has a great influence on the cleaning of the oil and the performance of the system, and the reliability and service life of hydraulic components. The main causes of hydraulic oil pollution in hydraulic bending machine are as follows: first, the outside of hydraulic actuator is dirty and debris enters the hydraulic system; Two is not used when refueling filter filter; Three is the use of containers unclean; Four is to check the amount of oil when impurities enter; Five is the serious wear and damage of the seal can not be replaced in time; Six is to check the repair of impurities iron filings and other impurities are not clean; Seven is improper storage of oil, debris into the tank, such as water. In the use and inspection and maintenance process, remember to pay attention to the above problems, can reduce the occurrence of hydraulic system failure.
To prevent air from mixing into the hydraulic oil of hydraulic bending machine, resulting in cavitation phenomenon
The compressibility of hydraulic oil in hydraulic bending machine is very low, but the compressibility of air is large. If the hydraulic system contains a small amount of air, it has a great influence on the system performance. The air dissolved in the water, when the pressure is low, will overflow a large number of bubbles, the formation of cavitation phenomenon; If the pressure is high, under the impact of pressure, bubbles quickly burst, producing explosive noise, and releasing a large amount of heat energy, resulting in the destruction of components and heating of oil. In order to prevent air from entering the hydraulic system, the following points must be done: first, the return pipe is inserted below the oil level; Second, to prevent joint loosening, sealing damage; Third, when refueling to the tank, avoid incorrect refueling methods; Four is to avoid the hydraulic pump inlet put fine filter caused by oil absorption resistance, dissolved gas can not be separated out.
To prevent excessive temperature of hydraulic oil of hydraulic bending machine
The temperature of hydraulic oil of hydraulic bending machine is generally better controlled between 40℃ and 80℃. If it is above 80℃ for a long time, it will cause the viscosity of oil to be very low, easy to leak, resulting in high temperature of hydraulic components and short life. All aspects should be considered adequately on the choice radiator so. The oil viscosity is selected, want to consider, the energy loss in the high viscosity increasing oil flow, low viscosity will multiply leak, so when use should pay attention to and regular inspection, to prevent the oil temperature is too high, and regularly of hydraulic bending machine hydraulic oil filter, regular inspection, so that can guarantee the workability of the hydraulic system, also can reduce the wear and corrosion of hydraulic components, Prolong the life of hydraulic system.
Bending machine is divided into manual bending machine, hydraulic bending machine and hydraulic bending machine. Hydraulic bending machine can be divided into: torsional shaft synchronization, machine-hydraulic synchronization, and electro-hydraulic synchronization. Hydraulic bending machine according to the way of movement can be divided into: moving up, moving down. Comprises a bracket, a workbench and a clamping plate, the workbench is arranged on the bracket, the workbench is composed of a base and a clamping plate, the base is connected with the clamping plate through a hinge, the base is composed of a shell, a coil and a cover plate, the coil is arranged in the depression of the shell, the top of the depression is covered with a cover plate.
