Hydraulic oil replacement

Dear engineering partners, Have you ever experienced the embarrassment of a grouting machine suddenly "going on strike"? Perhaps it's just because you neglected daily maintenance. Today we'll talk about how to take care of your grouting equipment like you take care of your car, so that they always stay in the best condition.   ​​Preventive maintenance checklist   1.Daily must-dos: Immediately flush the pipeline with clean water after construction to prevent the slurry from solidifying. A customer reported: "After sticking to this habit, the service life of the plunger pump has been extended by 2,000 hours. 2."Weekly inspections: Seal wear (recommended to replace every 500 hours) Hydraulic oil cleanliness (replacement is required if turbidity exceeds ISO 18/16) Electrical connector waterproofing 3.Seasonal maintenance: Empty the water tank in winter to prevent freezing, and pay attention to motor heat dissipation and ventilation in summer. ​​Troubleshooting tips​​ When you encounter pressure fluctuations, check these three places first:   Is the one-way valve stuck (it can be cleaned by soaking in kerosene) Is the pressure gauge calibration offset (professional inspection is required every year) Is the mixing ratio correct (water-cement ratio error exceeding 5% will affect pumping) ​​New trend in smart maintenance​​ The latest generation of grouting machines are equipped with IoT modules, and data such as accumulated working hours and maintenance reminders can be viewed through mobile phone APP. A dam engineering team reduced maintenance costs by 45% through a predictive maintenance system.
