Hydraulic drive technology has penetrated almost all modern engineering fields. Compared with mechanical drive and electric drive, hydraulic drive has unique advantages:
1. Hydraulic drives generate more power than electrical devices at the same volume.
2. With the same power, the hydraulic drive is small in size, light in weight and compact in structure.
3. The hydraulic drive has stable quality, high mechanical efficiency and good low-speed load characteristics.
However, due to the friction loss and leakage loss, the energy loss of the hydraulic transmission system is large; the cleanliness of the oil is high, and regular replacement is required; the oil temperature change will affect the speed control and noise shortcomings.In addition, engineering machinery often works outdoors in dirt and sand, under wind, snow and rain.The working load is often variable and accompanied by vibration, and the working speed is often in transient transition with inertial shock.Therefore, there should be special requirements for the hydraulic system of Engineering machinery: it should have good environmental adaptability and reliable closure; it should have higher working reliability and sensitive ability of real-time strain; it should have better maneuverability, so that the system can be closed and can make various changes.Therefore, when using the hydraulic system, we should follow the relevant rules.
1. Select suitable hydraulic oil
Hydraulic oil plays the role of pressure transmission, lubrication, cooling and sealing in the hydraulic oil system. The improper selection of hydraulic oil is one of the main reasons for the early failure and durability decline of the hydraulic system.Hydraulic oils should be selected according to the number specified in the random "Instructions for Use". When substituted oils are needed under special circumstances, their performance should be the same as that of the original brand.Hydraulic oils of different grades cannot be mixed to prevent chemical reactions and performance changes.Dark brown, creamy white, odourful hydraulic oil is deteriorated and cannot be used.If you have used one kind of oil equipment, when replacing it with another kind of oil, pay special attention to the cleaning of the equipment, the reliable replacement of oil, and use automatic oil detection, cleaning and replacement equipment.
