How to judge the quality of the oil quality of the hydraulic shears machine?
Hydraulic shearing machines and CNC shears machines are the main ones. How ensure the quality of shears is very important in the process of use. Most shearing machine manufacturers naturally have their own set of measurement standards.
Oxygen buffer plays an oxygen leveling effect on the scissors cutting seat. Due to the serious air leakage, the leveling effect is greatly reduced, which affects the working condition of the shearing machine, and has a very large impact on the cutting edge of the shearing machine, and the vibration of the movement is aggravated.
At the same time, due to tight leakage, the compressed oxygen pressure of the whole machine cannot reach the working pressure, so the clutch cannot be opened. When the excavator olecranon scissors machine manufacturer sends the machine tool to the customer, it will carry some wearing parts with it, which is convenient for the customer to replace and reduce the maintenance due to the machine tool. series of losses.
How to judge the oil quality of a hydraulic shearing machine:
The first point: PESCO Hydraulic Device believes that the viscosity of the hydraulic shearing machine oil: is moderate viscosity is better, too large will increase the viscosity of the flow resistance in the pipeline, the shearing machine is too small, or the shearing lubrication conditions will also cause shearing between hydraulic components The volumetric efficiency of the worn pump decreases.
The second point: is good lubricity and wear resistance: good shear hydraulic oil must have good lubricity and wear resistance. The shearing machine manufacturer enables more lubrication coordination and avoids friction and shear wear between the components of the hydraulic components.
The third point: Viscosity temperature: This is the performance of the viscosity index, of course, the higher the index, the better. Viscosity Temperature resistance The correlation between viscosity and temperature is the viscosity becomes smaller at the higher temperature. In the field shears that have been operated, the temperature of the hydraulic oil will change with the temperature change of the shear plate body and the surrounding temperature of the equipment, and the viscosity should not be greater than 90% and less than the usual viscosity.
The fourth point: Anti-oxidation stability: It is popular that the temperature of hydraulic oil increases and oxygen-containing chemical reactions occur at the same time. Many experiments have shown that when the temperature of the oil rises by 10 degrees, the oxidation reaction is twice as fast. The scissors have a good anti-oxidation effect of deterioration and are not easily oxidized, and the hydraulic oil can be a normal cycle.
The fifth point: is good shear stability: In order to improve the viscosity with the wild, hydraulic pendulum shears are added to the shearing polymethacrylate hydraulic oil, the molecule is formed by the action of the material hydraulic shears, through this reaction to increase the shearing capacity of the gate shears hydraulic oil.
Sixth point: There are two aspects to the shearing machine hydraulic oil emulsion and anti-foaming. A mixture of water and oil emulsion separates the water. Anti-foam bubbles in the fluid are mixed with the resulting water agitation.
