As an indispensable and important equipment in modern tunnel engineering, the stability of its performance directly affects the quality and progress of construction. Therefore, regular systematic inspection and maintenance of wet concrete spraying machine equipment is the key to ensure its normal operation and extend its service life. This article will introduce in detail how to conduct a comprehensive system inspection of wet concrete spraying machine equipment before construction to ensure smooth construction.
I. Pumping system inspection
1. Hydraulic system inspection
- Hydraulic pipeline connection: First check whether there is oil seepage or oil leakage at the connection points of each pipeline in the hydraulic system. If any leakage is found, stop using it immediately, find the oil leakage point and repair it in time.
- Oil stain inspection: Whether there is oil stain on the ground is also an important basis for judging whether the equipment is normal. Oil stains on the ground usually indicate that the equipment is leaking oil, which should be given enough attention.
2. Hydraulic oil tank oil level inspection
- Oil level monitoring: The oil level in the hydraulic oil tank must be within the range required by the level gauge. If the oil level is lower than the standard, the equipment may not operate normally, so the oil must be replenished in time to ensure that the hydraulic system of the equipment can maintain normal pressure.
3. Pumping system water tank inspection
- Water volume monitoring: Check whether there is enough clean water in the water tank to ensure the normal operation of the cooling and lubrication system when the equipment is running. If the water volume is insufficient, it should be replenished in time.
II. Lubrication system inspection
1. Automatic lubrication pump inspection
- Lubricating oil level: Check whether the lubricating oil in the oil box of the automatic lubrication pump is sufficient. Insufficient lubricating oil may cause wear of the equipment when it is running under high load. Pay attention to replenishing sufficient lubricating oil during each inspection.
2. Manual lubrication point maintenance
- Grease gun operation: Use a grease gun to lubricate the manual lubrication points on the equipment to ensure that all moving parts are in good lubrication condition. This operation helps to reduce the wear rate of the equipment and extend its service life.
III. Accelerator system inspection
- Accelerator box inspection: The adequacy of the accelerator directly affects the spraying effect of the concrete. Therefore, before each construction, the reserve in the quick-setting agent box should be checked. If it is insufficient, it should be replenished in time to ensure that the concrete can set quickly during construction.
IV. Inspection of other key components
1. Nozzle inspection
- Check whether the concrete nozzle is worn. The wear of the nozzle will directly affect the spraying effect of the concrete and needs to be replaced in time.
2. Inspection of the delivery pipeline
- Concrete delivery hose and steel pipe: Check whether the concrete delivery hose and steel pipe have wear, cracks or other signs of damage to ensure the integrity of the pipeline.
- Hydraulic oil pipe and air duct: Check the hose and steel pipe parts of the hydraulic oil pipe and air duct. If they are severely worn, they should be replaced in time to prevent the equipment from malfunctioning during high-pressure operation.
System inspection of concrete wet spraying machine equipment is an important part of ensuring construction quality and safety. Through a comprehensive inspection of the pumping system, lubrication system and key components, equipment failure can be effectively prevented, construction efficiency can be improved, and the smooth progress of the project can be ensured. Regular maintenance and inspection not only extend the service life of the equipment, but also reduce the risk of downtime due to equipment failure during construction.
