“…This is explained by the fact that low-humidity feed mixtures have fairly high viscoplastic properties, which lead to a decrease in the speed in the suction line by 3...4 times. In this case, the feed mixture does not have time to fill the working chamber of the pump, and therefore the efficiency decreases and pump delivery [11][12][13][14][15][16].…”

The article presents the results of an analysis of experimental studies of a rotary lobe pump with a separator and a screw feeder. The pressure loss in the feed line, the influence of the shape of the separator and the angle between its working edges on the performance characteristics of the pump, the influence of the performance of the screw feeder on the characteristics of the pump and the influence of the rotation speed of the pump shaft on its characteristics are studied. characteristics. As a result of experimental studies, it was established that a rotary pump with a screw feeder reliably transports feed mixtures with grass paste with a moisture content of 74% or more and feed mixtures without grass with a moisture content of 68% or more at a pressure in the discharge line of 0.4 MPa. In this case, the speed of the feed mixture in the suction cavity of the pump must be at least 0.42 m/s, which is ensured by a screw feeder.

The article focuses on the advantage of liquid mixed feeds in the use of mixed feeds for small farms and farms. The analysis of the scientific research works devoted to the problems of transportation and distribution of liquid mixed feed using pipelines showed that the physical and mechanical and rheological properties of such feeds have not been fully studied, and special feed pumps designed for the transfer of liquid mixed feeds with high viscosity have not been created. The article describes the structure and principle of operation of the small-sized liquid mixed feed preparation, transfer and distribution unit created by the authors. All equipment included in the unit has been modernized considering the peculiarities of small farms. Based on the results of the study, the necessary conclusions were drawn.

A method for testing volumetric pumps

Abstract: This article describes a convenient method of checking the delivery rate of volumetric pumps at low flow rate settings. The method employs a tester previously described for use with syringe pumps.
