We know that the use of machinery and equipment requires maintenance, and concrete pump trucks are no exception. They require maintenance after a period of use, such as how many kilometers a car has run or how long it has passed before it needs maintenance. We have summarized the individual inspections required for daily maintenance of concrete into 14 items. Maintenance is determined based on the usage time. Generally, maintenance is required when the usage time is up. It is safer to use. Secondly, it is necessary for the pump truck to use lubricating agent from a legitimate manufacturer as lubricating pump. The quality of the lubricating agent will also directly affect the maintenance. It affects the maintenance time of the pump truck or the service life of the pump truck.
1. Daily basic inspection of pump trucks?
1. Standard hydraulic oil should be transparent, light yellow, non-emulsified, and non-turbid.
2. The lubricating oil tank and each lubrication point are filled with grease, and the water tank is filled with clean water.
3. Check the sealing of the piston of the concrete pump truck, and no mortar shall penetrate into the water tank.
?? 4. Check the cutting ring, the lens gap is normal (maximum gap 2mm).
5. Check the working condition of the lubrication system. You should see that the indicator rod of the progressive oil separator moves forward and backward, and there is oil leakage at the S-tube rocker bearing position and the stirring shaft bearing position.
6. Check whether the functions of each electrical component are normal.
7. Check the swing of the distribution valve and whether the stirring device is normal.
8. Check whether there is dirt on the outside of the cooler. Dirt can easily cause the oil temperature to overheat.
9. Check whether the hydraulic system is leaking oil, whether the fuel tank cap seal is loose, and whether water is entering the water inlet.
10. Check the hydraulic oil level. The quality of the oil should be yellow and transparent, without emulsification or confusion, otherwise it should be replaced.
11. Check whether there is moisture mixed in the hydraulic oil. The funnel shape of the bottom ball valve at the bottom of the tank should be unscrewed and drained every 3 days. Do not allow hydraulic oil to escape.
12. After each maintenance, maintenance or replacement of hydraulic oil and filling of grease, the residual hydraulic oil and grease on the pump truck must be cleaned or cleaned.
13. Routine maintenance requires regular removal of vehicle oil stains.
14. Chassis maintenance should be carried out by the chassis factory service station or factory employees, and private processing is strictly prohibited. ?
2. Maintenance of the pump truck after 50 hours of operation (1500/2500)
1. Carry out the aforementioned maintenance.
2. Check all screw connections to ensure they are secure.
3. Check the connection of the piston rod in the water tank to ensure that the connection is firm and reliable.
4. Check the vacuum gauge indication and filter conditions.
3. Maintenance of the pump truck after 100 hours (3500/5000)
1. Carry out the aforementioned maintenance.
2. Check whether the wear of the glass plate and cutting ring is serious. If the wear is serious, replace the cutting ring.
3. Check whether the wear of the concrete piston is serious. If the wear is serious, replace the cutting ring.
4. Check the deterioration and emulsification of the hydraulic oil. Otherwise, change the oil completely and clean the tank thoroughly. ?
4. Maintenance after the pump truck has worked for 500 hours (15000/25000)
1. Carry out the aforementioned maintenance.
2. Check the positional wear of the S-shaped tube and S-shaped tube bearing.
3. Check the hydraulic oil. If necessary, the hydraulic oil should be replaced with new one. Newly added hydraulic oil must comply with national standards. Under normal circumstances, 10,000 square meters should be replaced when pumping water.
4. Check whether the air pressure of the energy storage device is sufficient. The air pressure of large energy storage devices is 8~9 MPa.
5. Check the joints and welds of structural parts.
6. Check the oil level of the distribution box to see if it needs to be replenished or replaced.
5. Maintenance of the pump truck after 750 hours of operation?
1. Carry out the aforementioned maintenance.
2. Check the wear of the concrete cylinder and replace it immediately if the coating is severely worn.
3. Completely debug the pump to ensure that the performance parameters meet the requirements. </p
