In the process of construction of small fine stone concrete pump truck, in addition to daily operation and maintenance, it is very necessary to clean the conveying pipe and pumping system. Because whether it is a small fine stone concrete pump or a fine stone concrete pump truck, because the concrete aggregate is conveyed during the construction process, it is inevitable that it will remain in the conveying pipe due to the poor fluidity of the aggregate. It is also necessary for the small fine stone concrete pump truck to prevent pipe blockage, and it is also necessary to do a good job of the gas delivery pipe and the pumping system.
About the cleaning process of fine stone pump delivery pipe and pumping system
Specific about the cleaning method of small fine stone concrete pump truck, Xiaobian is here today to share with you. The main thing is to carry out cleaning work from two aspects: hopper, S tube, etc.
1. Cleaning of the hopper: After suspending construction, first open the discharge port under the hopper to remove the residue of concrete impurities inside and outside the hopper, and close the discharge port after washing with water. When the screen above the hopper is opened for repair, it must be stopped before operation. Fill the hopper with fresh water, and use the positive pump to completely remove the residues in the hopper, S tube, transport cylinder, and transport tube until the sponge ball comes out of the tail hose, and then continue the positive pump.
2. Cleaning of the S-tube; continuous pumping should be performed immediately when the S-tube is in place. After the jog distribution, put the S tube to the side and insert the sponge ball into the concrete cylinder. Then, manually restore the S tube, seal the concrete delivery cylinder stuffed with the sponge ball, and continue to pump clean water to flush the remaining concrete residue in the pipeline until clean water flows out of the tail hose. Open the discharge port to drain the remaining water, and then close the discharge port.
In fact, the cleaning work of the conveying pipe and pumping system of the small fine stone concrete pump truck mainly starts from the hopper and the S pipe. No matter how powerful the equipment is, it is inseparable from maintenance and after-sales. There is no small fine stone concrete pump truck that can be used for a long time without maintenance. Every step must be done according to the cleaning standards.
