How to ensure the quality of hydraulic shears?

Hydraulic shears and CNC shears are mainly used. In the process of using, how to ensure the quality of shearing is very important. Most shearing machine manufacturers naturally have their own set of measurement standards.

How to ensure the quality of hydraulic shears? How to judge the oil quality of hydraulic shears?

CNC Shearing Machine

The oxygen buffer is used for the oxygen leveling effect on the scissors. The air leakage is tight, which causes the leveling effect to be greatly reduced, which affects the situation of the shears, and the blow to the shears of the shears is very, very large, and the method makes the sensation worse. .

At the same time, due to the tight leakage, the compressed oxygen pressure of the whole machine cannot reach the working pressure, so that the clutch cannot be opened. The CNC shearing machine manufacturers will carry some wearing parts randomly when sending the machine to the customer, which is convenient for the customer to replace and reduce the cost of the machine. A series of losses caused by maintenance.

How to judge the oil quality of hydraulic shears:

The first point: Wuxi Shenchong believes that the viscosity of hydraulic shearing oil: moderate viscosity is better, too large an increase in the viscosity of the flow resistance in the pipeline, the shearing machine is too small, or the impact of the shear lubrication conditions will also lead to shearing between the hydraulic components The volumetric efficiency of the wear pump has decreased.

The second point: good lubricity and wear resistance: good shear hydraulic oil must have good lubricity and wear resistance. Shearing machine manufacturers make more coordination of lubrication and avoid friction and shear wear between hydraulic components.

The third point: Viscosity Temperature: This is the performance of the viscosity index, of course, the higher the guillotine shear index, the better. Viscosity The correlation between the viscosity of the temperature resistance and the temperature, the viscosity becomes smaller at higher temperatures. In the field shears that have been operated, the temperature of the hydraulic oil will change with the change of the machine body and the surrounding temperature of the shearing plate of the equipment, not more than 90 and less than the usual viscosity.

Fourth point: Anti-oxidation stability: It is a popular hydraulic oil that has an oxygen-containing chemical reaction at the same time as the temperature rises. Several experiments have shown that the price of the shearing machine, when the temperature of the oil rises by 10 degrees, is twice that of the oxidation reaction. Scissors have a degraded anti-oxidation effect, good stability and not easy to be oxidized, and hydraulic oil can be a normal cycle.

Fifth point: Good shear stability: In order to increase the viscosity with the wild, the hydraulic oil of the hydraulic pendulum shears is added in the shearing of the polymethacrylate, and the molecule is determined by the material of the hydraulic shears , Through this reaction, to increase the shearing capacity of the hydraulic oil of the guillotine shears.

Sixth point: Shearing machine hydraulic oil emulsion and anti-foaming in two aspects. A mixture of an emulsion of water and oil to separate water. Anti-foam bubbles in the fluid are mixed with the generated water by stirring.
