1. First, add room temperature water to the hopper of the delivery pump, and keep the rotating shaft in the hopper rotating at a constant speed;
2. Pour the powdery lubricant into the hopper that rotates at a constant speed;
3. Stir slowly for about 5 minutes. The liquid in the hopper will be thick, uniform, colorless and transparent;
4. Slowly pour the lubricant solution along the inner wall of the hopper of the delivery pump and start conveying. pump until a small amount of lubricant sprays out;
5. As the lubricant lubricates the pumping pipe, the lubricant begins to spray out;
6. Pumping machine Gradually in a constant state, a large amount of lubricating agent is sprayed out;
7. The lubricating agent gradually disappears in the transportation pipeline, and the concrete is sprayed out mixed with the pumping agent;
8 , the pumped concrete is completely sprayed out, the lubricant is completed to lubricate the delivery pipe, and the concrete is pumped. </p
