Grouting pump working principle

Note: The injection pump works by compressing oil or compressed air, and its working principle is to use the large area of ​​the cylinder and grouting pump so that the cylinder can be produced with a small pressure Injection pressure. Next, the working principle of grouting pump will be analyzed in detail. Working principle of grouting pump Working principle shown in Figure 1, when the crank to the angular velocity ω counterclockwise rotation, the piston to the right, a sudden increase in the volume of the cavity, the cavity liquid pressure decreases, the suction valve opens under the pressure outside While the discharge valve is closed, the liquid being delivered overcomes the resistance loss of the suction line and the suction valve under the action of the pressure difference into the cavity. When the crank rotates 180 °, the piston moves to the left, the liquid is squeezed, and the liquid pressure in the chamber increases sharply. Under this pressure, the suction valve is closed and the discharge valve is closed. The liquid in the chamber is forced by the pressure difference Discharge to the discharge pipe to go. When the crank is constantly rotating at the angular velocity ω, the reciprocating pump continuously aspirates and discharges the liquid. Grouting pump has many outstanding advantages, such as its simple structure, applicability, high efficiency, displacement, mobility, maintenance are very convenient. At the same time, good safety, explosive, temperature changes and other environment, it has a relatively strong work efficiency. It is believed that expediting the study of the working principle of grouting pumps will provide better help for the future of such products.
