Fully automatic high-speed slurry filling machine automatically compensates the combined seal ring piston including piston rod and piston head. A seal ring assembly is provided on the outer circumference of the piston head. The seal ring assembly is formed by superimposing at least two seal rings. The contact surface between the upper and lower layers is a concave-convex fit, in which the curvature of the convex surface is slightly larger than the curvature of the concave surface. The convex surface allows the concave edge to expand outward. In addition, there is a compensation cover on the top of the seal ring assembly and a compression spring on the compensation cover. This automatic high-speed deep-slurry filling machine automatically compensates the sealing performance of the combined seal ring piston, and can automatically compensate after wear. The filling measurement accuracy is high, the seal ring has a long service life, and the operation is stable and reliable.
