Problems solved by technology

[0012] The pressure distribution on the sealing surface of the suction pipe 102 with a wall thickness of about 20 mm is basically uniform. The difference between the diameter of the central part and the diameter of the end part of the convex calender roll 103 is about 10 mm, although it can be considered to further increase the difference in diameter to seal central part, but, but if Figure 19 As shown, when the extreme convex calender roll 104 with a diameter difference of more than 10 mm is used, the two ends cannot be sealed instead.

Embodiment Construction

[0046] Hereinafter, the best mode for carrying out the squeeze pump rubber roller of the present invention will be described with reference to the drawings. figure 1 It is an overall sectional view of a squeeze pump having a rubber roller for a squeeze pump of the present invention. figure 2 is a cross-sectional view of the suction pipe. image 3 It is a cross-sectional view showing a state in which the suction pipe is pressed by a rubber roller whose both ends are cylindrical. Figure 4 It is a cross-sectional view showing a state in which the suction pipe is pressed by a rubber roller whose both ends are truncated cones.

[0047] Squeeze pump 1 is used to pressurize and convey fluids such as ready-mixed concrete, which has pump casing 2, suction pipe 3, rubber roller 4, and gyrator 5; The above-mentioned suction pipe 3 is bent along the inner peripheral surface of the pump casing 2 and installed in the pump casing 2; the above-mentioned rubber roller 4 is rolled to make ...

Abstract

The invention provides an extrusion-typed rubber roller used for a pump; the rubber roller can reduce the difference between the maximum sealing surface pressure and the minimum sealing surface pressure to the greatest extent when the suction pipe of a thick wall is extruded, and cause the sealing surface pressure of all the parts to be set within a better scope. The axial central part of a rubber roller (4) is a convex camber (6). Two axial end parts of the rubber roller (4) are a cylinder part (9) or a circular cone part (10). The rubber roller (4) is installed and arranged on an extrusion-typed pump (1). One side of the rubber roller (4) extrudes the suction pipe (3) of the thick wall, and the other side thereof rolls. The convex camber (6) can improve the sealing surface pressure of the central part and does not reduce the sealing surface pressure of the two end parts.

Description

technical field [0001] The invention relates to a rubber roller for a squeeze pump. The rubber roller for a squeeze pump is installed on a squeeze pump, and rolls while squeezing a suction pipe, thereby sucking in from one end of the suction pipe. Fluids such as ready-mixed concrete are discharged from the other end of the suction pipe. Background technique [0002] Generally, in squeeze pumps, the suction pipe is bent and installed in a cylindrical pump casing, and the rubber roller that squeezes the suction pipe from the curved inside of the suction pipe is rolled, thereby sucking the suction pipe from one end of the suction pipe. The incoming fluid such as ready-mixed concrete is discharged from the other end, and the fluid such as ready-mixed concrete is conveyed under pressure (for example, Patent Document 1). [0003] exist Figure 17 shows the roll axial distribution of the seal surface pressure when a general suction pipe is squeezed with various rolls. Here, the s...
