How to clean fine aggregate concrete pump?

Fine aggregate concrete pump plays a very important role in the construction works warm, it can greatly improve the efficiency of construction warm. However, in the use of fine aggregate concrete pump in the process, pay attention to cleaning fine concrete pump is very important. Exactly how to clean fine aggregate concrete pump it? Specifically, we now take a look.
Experts pointed out: fine aggregate concrete pump pipe in the construction process, to pump tube cleaning, which is an important step after pumping essential. Good cleaning method generally either cleaned pipeline, the pipeline and can be delivered to all of the concrete casting location, not only to save the amount of concrete machinery, but also a considerable economic environment. Specifically, the step of cleaning the fine aggregate concrete pump has the following steps.
1. Check the cutting ring and glasses board
Check the cutting ring and eye wear between the plates, which is the key to the success of the direct kick cleaning method. If the cutting ring and wear and tear is not serious eye plate, cutting ring and eye plate spacing <0.1 mm, and no more than one millimeter between them grooves scratch, you can use direct kick method for cleaning.
2, short pipe cleaning method
Under normal circumstances, after finished pumping concrete can be pumped 0.15 ~ 0.25m \ +3 cement ratio of 1.5 or 1:2 mortar, then fill the water in the dispensing valve to start pumping, the concrete pumping to pouring location, until the output of the delivery tube with water until the effluent. If the pipe is shorter, the cleaning effect is better, then the cleaning process ends.
3, long pipe cleaning method
If the pipe is longer or cleaning effect is not very good, you can open the hopper discharge gate, and then the anti-pump, hopper and dispensing valve rinse. If pumping up and highly> 20 m, you can choose to use a wooden hammer percussion section at the bottom of the vertical pipe, if percussion sounds very low, you need to bend apart, poured can accumulate a large aggregate.
