Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0021] like figure 1 As shown, a hose pump includes a pump casing 1, a rotor body 2, a frame 3 and a hose 4, the hose 4 and the rotor body 2 are both arranged inside the pump casing 1, and the pump casing 1 is arranged on the frame 3 Above; the cross-section of the rotor body 2 is elliptical, and two ends of the rotor body 2 are respectively provided with a pressure roller 21, and the pair of pressure rollers 21 can form...

Abstract

Disclosed in the invention is a flexible pipe pump comprising a pump shell, a rotor body, a base, and a flexible pipe. The flexible pipe and the rotor body are arranged inside the pump shell; and the pump shell is arranged at the base. The cross section of the rotor body is in an elliptic shape; compression rollers are respectively arranged at the two ends of the rotor body; and the compression rollers can exert rotation extrusion on the flexible pipe with rotation of the rotor body. Fluid adsorbed by the flexible pipe pump is only in contact with the flexible pipe and various fluid materials with different viscosities, densities, corrosion degrees, and corrosivities can be conveyed. Besides, a flexible pipe fracture detection apparatus is also installed in the pump shell, so that the damage of the flexible pipe in the pump shell can be found instantly and thus repairing can be carried out conveniently. With the side compression rollers, deformation recovering of the flexible pipe can be realized conveniently. Because the compression rollers and the rotor body are made from self-lubrication materials, no lubrication is needed. And a pulsation damper is arranged at the pump shell, thereby eliminating the pulse caused by pump movement and hammering during pump starting.

Description

technical field [0001] The invention relates to the technical field of positive displacement delivery pumps, in particular to a hose pump. Background technique [0002] There are many kinds of industrial pumps used for fluid transportation in modern industrial production, but there are not many industrial pumps suitable for conveying slurry fluids with high viscosity, strong corrosion and high solid content, and there are more or less Certain limitations. Such as domestically produced diaphragm pumps, the diaphragm quality is not high and the service life is short. Secondly, screw pumps, which are commonly used for slurry material transportation, are difficult to process and have high requirements for rotor processing. It is difficult for domestic manufacturers to reach the manufacturing level of foreign countries, resulting in a reduction in the service life of rubber stators. In addition, such as magnetic pumps and auxiliary impeller dynamic seal rubber-lined pumps, the...
