It can be said that the CNS truck mounted crane must rely on the existence of hydraulic oil to continue to work, because a lot of its work is used in the entire hydraulic system, and how often do you need to replace the hydraulic oil after long-term use? Here is CNS to introduce you.
Generally speaking, the hydraulic oil must be replaced by the CNS truck mounted crane for two to three years, and the theoretical oil change specification is to see the viscosity and embrittlement level of the hydraulic oil, such as whether it is clean, and the specific daily work is based on the working condition and work experience. Crane hydraulic oil does not have to be replaced regularly like engine oil. As long as it can be clear that the hydraulic oil tone does not change, there is no sediment inside, there is no foul smell, and it can be applied again without replacement. The hydraulic oil filter element can be replaced appropriately according to the application condition.
Many of the positions of the crane are dependent on the overall completion of the hydraulic press management system, and the hydraulic oil plays a key role in the telescopic boom, the rotation of the rotary table, the lifting and extension of the boom, and the extraction and extraction of the feet, etc. On the one hand, it provides the working pressure of the management system, produces standard air pressure in the middle of the sealed chamber to complete the movement, and on the other hand, it has the effect of wetting. As everyone knows, hydraulic oil also has a service life, and must be replaced immediately when used to a certain period of time.
In the new original crane or crane after maintenance, it is necessary to replace the compression oil every hour for three months in the early application and clean the car fuel tank. Because the residue caused by the hydraulic system in the run-in period of the crane in the early application and the residue in the pipeline will flow with the hydraulic oil to the car tank, it is necessary to replace the hydraulic oil and clean the car tank at three months. If the replaced hydraulic oil does not cause emulsion and mildew, it can be deposited for 48h and filtered to be applied again; If it causes emulsion and mildew, it should be replaced immediately. In all normal operating environments, the hydraulic oil should be filtered once every half a year, but the hydraulic oil number is more than 2 years. Because the majority of common failures are caused by electrical hydraulic oil is not cleaned.
The hydraulic oil of the new car is recommended to replace it in half a year or ten months, and the E-mail box is also cleared when the oil is changed to avoid metal powder and vulcanized rubber powder in the bottom box. If there is a vacuum oil filter, it is cost-effective, and the oil can be pumped into the clean gasoline drum with the vacuum oil filter, and then the oil can be collected back into the car tank with the vacuum oil filter. Later see how much oil shortage is how much to make up.
The above is the "frequency of replacing hydraulic oil with crane" shared by CNS. I hope it can help you. The replacement time of new cars and old cars is not the same, so you need to clarify this premise first.
