Abstract

Invention M..6. used for pumping fluids of particularly increased viscosity and allows for increased pump performance. Vacuum rollers (P) 6 and 7 are mounted on the rotor 4 in pairs on both sides of the hose 2 and are oriented axes 9 and 10 perpendicular to the axis of the push rods. Axis 10 of each P 7 is hinged on the rotor and equipped with a supporting P on the end 11. In the housing there is a guide track 12 for the Pile curved lead-in and output portions. With this design, the hose is covered with P 6 and 7 throughout the cross-sectionalimeter, which ensures reliable restoration of the cross-sectional shape of the hose, and hence the filling of its cavity. 6 Il.

FIG. five

The invention relates to pump construction, relates to pshangovye pumps and can be used in various industries of the national economy for pumping fluids, especially viscous viscosity.

The aim of the invention is to increase pump performance.

FIG. 1 shows the proposed pump, a general view; in fig. 2 is a view A of FIG. I; in fig. 3 is a section BB in FIG. one; in fig. 4 is a view of B in FIG. 3; in fig. 5 is a view of FIG. 3 (view of the output part of the guide track with a support roller); in fig. 6 is a view of D in FIG. 1 (view of the lead-in part of the support track).

The hose pump includes a housing 1 in which an elastic hose 2 is placed on a cylindrical support surface and interacts with pressure rollers 5 mounted on axles 3 in the rotor 4 and with vacuum rollers 6 and 7 having a spheroidal concave surface 8 with a radius equal to the outer radius the surface of the hose 2. The vacuum rollers 6 and 7 are mounted on the rotor 4 in pairs on both sides of the hose 2 and are oriented axes 9 and 10 perpendicular to the axis m 3 of the pressure rollers 5. At the same time, the axis 10 of each external vacuum

roller 7 is mounted on the rotor 4 as a ball and provided with a support roller 11 at the end, and in case 1, a guide track 12 is made for the support roller 11 with curved feed part 13. The exit part 14 of the guide track is also curved.

When the rotor 4 rotates, the rollers 5 are rotated through the hose 2, outlive it and move the pumped medium to the consumer. Vacuum rollers 6 and 7 cover the hose 2 from both sides, restoring its cylindrical shape after pinching by rollers 5 and ensuring reliable suction of the pumped medium. Outdoor

the vacuum rollers 7 are held in the position of the hose coverage 2 by the support rollers 11 moving along the guide track 12. On the output part 14 of the track 12, the axis 10 of the roller 7, falling on the curvilinear section, leans back, releasing the hose 2. On the front part 13 of the track 12

the support roller 11 of the axle 10 catches the curved part and, moving along it, enters the guide track 12. At the same time, the axis 10 of the vacuum roller 7 rotates into a working position, in which the rollers 7 span the hose 2.

By covering the hose 2 with rollers 6 and 7 along the entire perimeter of the cross section, it is possible to reliably restore the shape of its cross section and, consequently, fill the cavity of the hose 2. This contributes to increasing pump performance.
