Here is the content list:
l Six types of maintenance for concrete mixer truck.
l Maintenance guide for concrete mixer truck.
1. New car maintenance, also known as trial operation maintenance. A new car or a vehicle after overhaul needs a trial run. After the trial run, the vehicle must be maintained. Its main contents are: cleaning the lubrication system, replacing the lubricating oil, re-tightening the cylinder head nut according to the specified torque, checking and adjusting the transmission belt, operating mechanism, valve clearance, and fastening the connecting parts, etc.
2. Shift maintenance, also known as daily maintenance. The 8x4 concrete mixer truck should be cleaned and inspected after the daily operation. When it is found that the lubricating oil and cooling water are insufficient, they should be added again.
3. Regular maintenance, also known as maintenance according to the specified period. That is generally referred to as technical maintenance.
4. Storage and maintenance is the maintenance that is required when the concrete mixer truck is parked idle for a long time or sealed for storage. Maintenance content is mainly cleaning, cleaning, lubrication, protection, and so on. Its purpose is to prevent or reduce the adverse effects of various harsh conditions on the machine during storage, and to ensure that the concrete mixer truck is always in a good standby state.
5. Seasonal maintenance is a kind of seasonal maintenance that will be carried out temporarily before winter or summer. Its purpose is to adapt the work of the concrete mixer truck to solve changing requirements. The main maintenance content is: to clean the fuel and lubrication system and replace the fuel and lubricating oil that meet seasonal requirements. Add or replace the antifreeze, and check whether the thermostat is working normally.
6. Type maintenance is the responsive maintenance performed after a major abnormal event occurs on the CNG concrete mixer truck. If the engine has a speeding accident, when the speeding is stopped, it is necessary to carry out secondary maintenance on the crank connecting rod mechanism and other related parts, so that the technical status of these parts and components can be completely restored to normal before restarting the operation.
1. Grease the place where there is a grease nipple once a week to ensure normal lubrication. In addition, butter should be added to the joint surface of the tugboat and the raceway every 3 to 4 days to keep it normal.
2. The hydraulic oil and reducer oil should be replaced once every 100 days when the new concrete mixer truck is used. No. 68 wear-resistant hydraulic oil should be used in the oil storage tank of the hydraulic system. It is recommended to use No. 46 hydraulic oil in cold regions. The reducer uses No. 90 heavy-duty gear oil, and it is recommended to use imported Shell and other oils with better quality.
3. After the new car is used for 1 to 2 weeks, the connecting bolts and saddle bolts of the sub-frame and the main frame of the main car should be re-tightened, and then tightened every half a month.
4. After the new car is used for 1 to 2 weeks, check whether the fixing bolts of the supporting wheel seat, the flange of the oil pump, and the connecting bolts of the transmission shaft are loose, and then tighten them once a month.
5. Clean the inside and outside of the mixing drum every time you finish work to ensure that there is no accumulation in the mixing drum. If the unloading time at the construction site exceeds 2 to 3 hours, the inside of the mixing drum should also be cleaned when returning.
6. After using for some time, check the integrity of the sealing skin of the feeding hopper and replace it in time if it is severely worn, otherwise it will easily cause the mouth of the barrel or the feeding hopper to wear.
7. When washing the 6x4 concrete mixer truck, it should be noted that the high-pressure water flow cannot be aimed at the flange sealing ring of the reducer, so as not to damage the lubricating grease.
8. If flushing is aimed at the sealing ring, there is a possibility of splashing sand and other sundries, which will cause damage to the sealing ring and machine parts and affect the use.
9. Check the position of the hydraulic oil every time before leaving the vehicle. The oil level should be 2-3cm higher.
10. The overall pump should check the oil level of the hydraulic oil system once a month, and the oil level should reach the bolt groove.
11. Every time the rear control handle changes from stirring to unloading or from unloading to stirring, it must pause in the middle position, and perform the next action after the mixing drum stops rotating. Do not continue to use force when the handle is pulled to the limit position to prevent the oil pump from being stuck.
