For small concrete pump trucks, as a common mechanical device, cleaning is also very important. If the dirt left by the small concrete pump is not dealt with in time, it will be very easy to leave a layer of sludge that is difficult to clean. This will easily lead to aging of the equipment tubing, hydraulic penetration, etc. When the small concrete pump is working, it is bound to be Will leave a lot of dirt, if not cleaned, it will affect the service life of the equipment. So how do you clean a small concrete pump truck?
Exploring how to clean up small concrete pump trucks:
As a common mechanical equipment, small concrete pump trucks are also very important for cleaning. If the dirt left by the concrete pump is not treated in time, it will be very easy to leave a layer of sludge that is difficult to clean. These can easily lead to aging of the equipment tubing, hydraulic penetration, etc. When the concrete pump is working, it is bound to stay. A lot of dirt, if not cleaned, will affect the life of the equipment. So how do we clean small concrete pump trucks?
Under normal circumstances, we use water to clean, the site has sufficient water supply, but when hitting high-rise buildings, the water level in the hopper rises, it is difficult to hit, and the cleaning is not clean. If cleaning with a cleaning ball, it is necessary to soak in water for 30 minutes in advance, put it into the cleaning ball, and the anti-pump operation cleans the dirt attached to the inner wall. Now we both introduce the common concrete pump cleaning methods:
When the pipe is long or the cleaning effect is not good, open the hopper discharge door, open the reverse pump, and rinse the hopper and distribution valve. If pumping up and the height is >20 meters, you can use a wooden hammer to strike the bottom bend of the vertical part. If the knocking sound is low, you need to disassemble the elbow and pour out the large aggregate that may accumulate.
Dismantling pipe method
After pumping, the pump is reversed for 1~2 cycles to eliminate the pressure in the conveying pipe. If pumping up, the shut-off valve must be closed to prevent backflow and then remove the discharge pipe. Open the hopper discharge door, and the reverse pump flushes the sputum in the distribution valve, the sump and the hopper. Pull out the mouth of the first 6B or 5B delivery tube and insert it into the water-washing cleaning ball or cylindrical cleaning piston. Close the dispensing valve discharge door, open if there is a shut-off valve, pump clean water until the piston is pumped out of the delivery tube output. The advantage of the stripping method is that the pipeline cleaning is relatively clean, and the flow rate of the water source can be low and can be suspended. The disadvantage is that it is difficult to connect again after the discharge port is disassembled, which is laborious and laborious. Concrete pump cleaning must be carefully and carefully cleaned, and no dirt should be left. This will help extend the life of the equipment.
