Use of concrete pump friends are aware of hydraulic oil, if the hydraulic oil to add a different additive, you can improve the hydraulic oil of different properties, such as the compatibility of the seals, oil can prevent the sealing material damage ; To improve the lubricating properties of oil; to prevent corrosion; better gas release; to prevent the formation of foam in the tank; oil, water separability; to reach the filter before the oil to maintain the oil floating property; Compatibility with paint. Can think of the importance of concrete pump hydraulic oil. Then the need to replace the hydraulic oil, then how to replace it. How long does it take for the replacement cycle? Haomei now describes how the concrete pump replaces the hydraulic fluid and the replacement cycle. I hope to be helpful.
In the normal use of concrete pump conditions under the oil drain cycle for one year to a year and a half. This cycle is not absolute, should also be adjusted according to the actual use; such as the use of the environment and temperature, working hours, mechanical conditions. Concrete pump can usually be combined with regular maintenance repair oil, in the new machine factory or overhaul of the walk after the expiry of the first two maintenance when the oil change, after the oil can be carried out in the three maintenance. Generally about 15,000m3 pumping should be a full oil change, and clean up the tank.
1. The system used to check the original hydraulic oil, the general color of the oil should be transparent with yellow, turbid or emulsified, to understand the extent of its pollution deterioration, and then put the net.
2. If the original oil is dirty, after the release should first use kerosene cleaning system, then the working oil or low viscosity naphthenic oil (50 ℃ kinematic viscosity 10 ~ 20 centistokes) cleaning. Cleaning to make oil pump gap operation, that is, turn stop. Oil pump to use a coarse suction filter (80 mesh filtration precision / inch), cleaned and then replaced the original design of the oil filter. Do not clean the tank with cotton or cotton cloth. Can be used in cleaning oil circulation after cleaning net, with the compressed air to blow the tank clean.
3. First check the new oil grade, quality, shall not use other brands, but can not mix the two brands.
