The cleansing of concrete pump receptacle is an essential and also vital action after pumping. A great cleansing technique can not just clean the conveying pipeline, however also deliver all the concrete in the pipe site, which not only does not lose concrete, but additionally economic and also affordable. There are 3 usual washing techniques for S pipe shutoff concrete pump, which are presented as complies with.
Direct Water Technique
1. Inspect the wear between the reducing ring and also the eye plate. If the cutting ring and the eye plate are not seriously used, the distance between the reducing ring and also the eye plate is lt;0.1mm, and there is no trench scratch of more than 1mm between them, the direct water drawing method can be used.
2.After pumping the concrete, then pump 0.15~0.25m \ + 3 mortar with water-cement ratio of 1 ∶ 1.5 or 1 ∶ 2, and then fill the water in the distribution valve, start the pumping, and send the concrete pump to the pouring site, until the output end of the conveying pipe flows out of clean water. If the pipe is short and the cleaning effect is good, then the cleaning process is over here.
3. When the pipe is long or the cleaning result is not very good, open the receptacle discharge door, open up the back pump, as well as wash the receptacle and also circulation valve tidy. If the pipeline is pumped up and the elevation is 20m, a wood hammer can be utilized to tap the bottom elbow of the vertical part. If the tapping noise is reduced, it is essential to open the arm joint and pour out the large accumulation that may be gathered.
4. Close the discharge door and also pump water till water flows from the outcome of the sharing pipeline.
The advantages of direct water pumping method: do not need to get rid of the product opening pipe as well as add the cleansing sphere, conserve time, pumping is easier to succeed, particularly hassle-free to cleanse the much shorter pipeline.
Downsides: ① big water usage as well as the pumping water should be continual, water is very easy to discharge in the putting website; ② if there is an upright upward pipe, the pipeline should be curved; ③ transmission pipe is long pipeline residues; ④ rigorous sealing of the distribution valve.
Get rid of the product pipe approach
1. After pumping concrete, reverse pump 1 ~ 2cycles to eliminate the stress in the communicating pipeline. If pumping up, the quit shutoff need to be closed initially to avoid concrete backflow, and afterwards get rid of the discharge pipeline.
2. Open up the receptacle unloading door, and also the reverse pump will certainly rinse the concrete in the circulation shutoff, concrete cylinder as well as receptacle.
3. Take out some concrete from the first 6B or 5B communicating pipeline mouth, and plug it right into the water-soaked cleaning ball or cylindrical cleaning piston.
4. Close the discharge shutoff of the circulation valve, open if there is a stop shutoff, as well as pump tidy water up until the piston is pumped from the outcome end of the communicating pipeline.
The benefit of the elimination pipeline method is that the pipe is clean and also the flow price of water can be reduced and also can be suspended. Its negative aspect is that it is tough to link again after opening, as well as laborious.
Plus piston method
1) Roll 10 ~ 20 concrete bags right into a column with a size a little less than the size of the sharing cyndrical tube, a slightly pointed head and a length of concerning 400mm, tie with fine cable, as well as connect the cleaning round on the tail of the cylinder with wire, and also soak with water.
2) After pumping the concrete, reverse pump 1 ~ 2 cycles to get rid of the stress in the sharing pipe, as well as press the switch to make the concrete cyndrical tube piston back to the last point. If it is pumped up and also there is a stop shutoff, it has to be shut initially to prevent concrete heartburn.
3) Remove the discharge pipe, open up the receptacle discharging door, and also the reverse pump will rinse the concrete in the distribution valve, concrete cyndrical tube as well as receptacle.
4) Shut the receptacle dumping door as well as include water to the receptacle. When the water is included in the diameter of the concrete cyndrical tube, tons the head of the cylinder right into the concrete cyndrical tube with a wood skid pole of a length of 1m and 30mm diameter, and also remain to include water to the elevation of the center line of the blending shaft.
5) Withdraw the crowbar, quickly start the pumping, and continue to include water until the cylinder is pumped from the outcome end of the sharing pipe.
The benefit of the piston approach is that the pipeline is tidy, the flow rate of the water can be reduced, can be put on hold, while minimizing the trouble of eliminating the electrical outlet and flexing pipe.
The downside is that the procedure needs are high, as well as the distribution shutoff is very easy to cut off the cyndrical tube.
The above 3 sort of pump cleaning methods have their very own advantages and disadvantages, among which one of the most dependable is the disassembly pipe approach, the most basic is to include piston method, if the conveying range is short, the straight water approach is additionally a great selection. The particular method must be determined according to the actual circumstance of the construction, in other words, to accomplish both effective and economic.
