Two ways to identify the hydraulic oil for backhoe loaders

The quality of backhoe loader hydraulic oil will not only affect the normal work of small loaders and other construction machinery, but also cause serious damage to hydraulic system components. Here are two ways to identify the hydraulic oil for the backhoe loader:

1, glass plate tilting method

Take a clean glass plate, place it horizontally, place a drop of the hydraulic fluid under test on the glass, and add a drop of standard hydraulic oil next to it. Then tilt the glass plate and observe the following: If the oil to be measured Both the flow rate and the flow distance are larger than the standard fluid, which means that the viscosity is lower than the standard fluid. On the contrary, the viscosity is higher than the standard fluid.

2, glass bottle inversion method

The tested hydraulic fluid and standard fluid were respectively contained in two transparent glass bottles of the same size and length, and the two bottles were plugged with stoppers. Place the two bottles side by side and then quickly invert both bottles at the same time. If the measured hydraulic oil bubbles in the bottle rise faster than the standard oil bubbles in the bottle, then the viscosity of the oil is lower than the standard oil viscosity. Otherwise, the viscosity of the oil is higher than the standard oil viscosity. If the speed at which the two oil bubbles rise is close, the viscosity is also similar.
