In Marine crane and other construction machinery, bearing is an important part, it can even be said that the state of the bearing directly affects its work efficiency, and even affects its service life. In addition to the wear of the bearing itself, corrosion is also one of the problems it faces.
In Marine crane and other construction machinery, bearing is an important part, it can even be said that the state of the bearing directly affects its work efficiency, and even affects its service life. In addition to the wear of the bearing itself, corrosion is also one of the problems it faces. Therefore, to prevent bearing rust also needs our usual attention, can prevent bearing rust, do a variety of anti-rust measures.
1, surface cleaning: cleaning should be based on the nature of the rust and the situation at the time to choose the appropriate method.
2, the surface can be dried with filtered dry compressed air after cleaning.
3. Impregnation method: Some small items are dipped in anti-rust oil and the surface is glued with a layer of anti-rust oil.
Brushing method: pay attention not to produce accumulation when brushing, but also pay attention to prevent leakage.
5, spray method: spray method can use solvent dilution type anti-rust oil or thin layer anti-rust oil, but there must be perfect fire and labor protection measures.
No matter what kind of method, we hope that you can find a more suitable method according to your own situation to cut off the necessary conditions for rust, then rust prevention is no longer a problem.
As we all know, the gear oil of the Marine crane should be replaced in time, because the gear oil is used for a long time, if it is not replaced immediately, then it will cause serious damage. The dock crane manufacturers should apply the Marine crane to reflect the after-sales service every year according to the feedback situation, and the information content of the maintenance level is high because the gear oil is not replaced with a new tanker for a long time, then it will cause serious damage. Marine crane manufacturers should reflect the after-sales service situation every year according to the feedback, the information content of the maintenance level is high, how to change the oil?
1. Upgrade the gear oil of Marine crane, extract the hydraulic oil in the hydraulic oil filter, remove the main pipe completely, clean the car oil tank and oil filter, clean the car oil tank with cleaning equipment, remove solid particles, such as the cleaning of the car oil tank to dry, re-use the special gear oil for cleaning the car oil tank, and then release it fully and neatly. To clean the dry conditions of the car fuel tank and to be able to introduce new gear fuel tanks to the car.
2, start the diesel engine, at a lower operating rate, to ensure the working state of the gasoline pump, all the actual operation of the dock crane, the introduction of new gear oil, will make each circulating system in the software to discharge the old oil, so that the old oil can not immediately enter the car tank, when the total oil pump injected new hydraulic oil, the gasoline pump can stop rotating, When the entire control loop is in the process of oil change, a new hydraulic tank should continue to be introduced into the vehicle to prevent the Marine crane's gasoline pump from sucking the empty tank.
3, ensure that the car oil tank and pump oil pipe connection is normal, can set the crane work, the oil level and liquid level into the tank car components tank, all processes must be operated by professional personnel, and in the case of standard conditions permit, by professional and technical personnel on-site guidance, to ensure that the Marine crane oil change work smoothly.
