During the long-term use of the crane, because the quality of the hydraulic oil in its hydraulic system will affect the service performance and service life of the entire crane, it is very important to learn to drain the waste hydraulic oil in the crane correctly, which is also a problem that drivers often care about. Then, the following section will introduce two ways to drain the waste hydraulic oil in the small crane. The details are as follows.
1. The hydraulic oil in the container is inverted
Take out the hydraulic oil from the oil tank and store it separately from the specified hydraulic oil in two clear glass bottles of the same size, and plug the bottle mouth. Arrange the two bottles side by side and put them upside down. If the bubbles of the measured hydraulic oil in the bottle rise faster than the bubbles of the standard oil in the bottle, it means that the viscosity of the hydraulic oil is lower than the viscosity of the standard hydraulic oil; On the contrary, the viscosity is higher. If the rising speed of the hydraulic oil bubbles in the two bottles is close, it means that the viscosity is similar and no dilution is required.
2. Glass plate deflection method
Take a clean glass plate, place it horizontally, drop the hydraulic oil on the glass, and drop a specified hydraulic oil around it, skew the glass plate, and investigate the flow rate and activity interval. If the flow rate and activity interval of the measured hydraulic oil are both larger than those of the standard hydraulic oil, it means that its viscosity is higher than that of the standard oil droplets, otherwise it will be higher. Note: The hydraulic oil needs to be replaced when the truck mounted crane operates for 2000 man hours, that is, about two to three years. The theoretical oil change specification is based on the viscosity and aging degree of the oil, such as whether it is clean, etc. In practice, it is based on working conditions and experience.
The above is a detailed introduction to the two methods of emptying waste hydraulic oil in small cranes, which I believe can help you to complete this work in a timely and efficient manner. Draining hydraulic oil and injecting hydraulic oil are two tasks that cannot be avoided when replacing the hydraulic oil of the crane. They will have a great impact on the use quality of the hydraulic oil of the crane. Therefore, we should have a good grasp of these two tasks, and we hope you can be familiar with them.
