Description

12

The invention relates to pump construction, peristaltic pumps, and can be used in various industries for pumping fluids.

The aim of the invention is to increase the efficiency and simplify the design of the pump.

FIG. 1 shows the structural scheme of the proposed pump; figure 2 is an elastic hose, transverse 2 section; in fig. 3 - pressure regulator in a flexible tube.

The pump comprises a housing 1 in which an elastic hose 2 is placed, interacting with the rollers 3 of the rotor 4 and having a flexible tube 6 placed in the internal cavity 5 filled with an elastic medium.

In the housing 1 under the hose 2 in the middle part of it there is a groove 7, the flexible tube 6 is located in the middle of the hose 2, and the hose 2 is additionally equipped with a flexible metal tape 8 placed in its inner page 5 with the possibility of interaction with the flexible tube. Tube 6 at the ends

closed by a pipe 9, in which a bellows compensator 10 is installed, which has an elastic pressure regulator in a flexible tube 6, made in the form of a spring 11 with an adjusting screw 12.

The pressure of the elastic medium in tube 6 tends to expand it. The tube 6 through the tape 8 acts on the hose 2, expanding it over the entire width of the section. The rollers 3 of the rotor 4, rolling on the hose 2, squeeze it and the tube 6., which then sinks into the groove 7. The movement of the pressed section through the hose 2 moves the pumped medium to the consumer.

Behind the pressed section, the tube 6 expands and, through the belt 8, restores the original shape of slag 2, ensuring the suction of the pumped medium. By adjusting the screw 12 with the force pressing the spring 11 to the compensator 10, it is possible to regulate the pressure of the elastic medium in the tube 6 and, consequently, the suction capacity of the pump.

PERISTALTIC TYPE PUMP, containing a housing in which an elastic hose is placed, interacting with the rotor rollers and having a flexible tube located in the inner cavity filled with an elastic medium, characterized in that, in order to increase the efficiency of the pump and simplify its construction, in the housing under a groove is made in the middle part of the hose, a flexible tube is located in the middle of the hose, and the hose is equipped with a flexible metal tape placed in its inner cavity with the possibility of interaction with the flexible tube. closed by a pipe 9, in which a bellows compensator 10 is installed, having a pressure regulator of the elastic medium in the flexible tube 6, made 5 in the form of a spring 11. with an adjusting screw 12. The pressure of the elastic medium in the tube 6 tends to expand it. The tube 6 through the tape 8 acts on the hose 2 ₅ expanding it over the entire width of the section. The rollers 3 of the rotor 4, rolling along the hose 2, squeeze it and the tube 6 ,. which at the same time is recessed into the sleeve 7. The movement of the clamped section through the hose 2 ensures the movement of the pumped medium to the consumer. Behind the clamped section, the pipe 6 expands and, through the tape 8, restores the original shape of the hose 2, ensuring that the pumped medium is sucked into it. By adjusting the screw 12, the force of the spring 11 to the compensator 10, it is possible to adjust 25 the pressure of the elastic medium in the tube b, and therefore the suction capacity of the pump.
