Устройство по п.1, отличающееся тем, что корпус устройства выполнен в виде цилиндра с верхним и нижним фланцами, причем поверхность верхнего фланца, обращенная к перекачиваемой жидкости, повторяет контур нижнего диска направляющего аппарата.3. Устройство по п.1, отличающееся тем, что в корпусе установлены уплотнения нажимной втулки, разделяющие внутреннюю проточную часть от внешнего пространства.4. Устройство по п.3, отличающееся тем, что уплотнения нажимной втулки являются прецизионно-щелевыми.5. Устройство по п.1, отличающееся тем, что на нажимной втулке установлен цилиндрический ролик в виде штифта, снабженного втулкой, а в корпусе выполнен, по крайней мере, один стопор в виде выступа.1. A device for determining the axial force acting on the impeller of the stage of a submersible vane pump, comprising a housing, a shaft, an impeller mounted on the shaft, a guiding apparatus and a force sensor, characterized in that a push sleeve made with axial movement is installed in the housing , on the outer surface of which a support shoulder is made, the axial end of which is pressed against the force sensor installed in the housing, the upper end of the pressure sleeve being the axial support of the impeller, made in the housing, p at least one window in the radial napravlenii.2. The device according to claim 1, characterized in that the housing of the device is made in the form of a cylinder with upper and lower flanges, the surface of the upper flange facing the pumped liquid repeats the contour of the lower disk of the guide apparatus. The device according to claim 1, characterized in that seals of the pressure sleeve are installed in the housing, separating the internal flowing part from the external space. The device according to claim 3, characterized in that the press bushings are precision slotted. The device according to claim 1, characterized in that a cylindrical roller is mounted on the push sleeve in the form of a pin provided with a sleeve, and at least one stopper is made in the form of a protrusion in the housing.
