Claims (2)

1. Полупогружной насос с валопроводом на подшипниках скольжения, состоящий из корпуса насоса, расположенного в емкости с перекачиваемой средой, рабочего колеса с лопатками, взаимодействующими с перекачиваемой средой, валопровода, представляющего собой последовательное соединение валов, установленных на подшипниках скольжения в нижней и верхних подвесках и корпусе уплотнения, отвода, опорной плиты, отличающийся тем, что перекачиваемая среда под давлением, создаваемым насосом, подается во внутренние полости насоса, поступает в зазоры между втулкой и вкладышем подшипников скольжения, обеспечивая их промывку, смазку и охлаждение, после чего через сборники выводится в область пониженного давления через устройство, определяющее расход перекачиваемой среды через подшипник скольжения.1. A semi-submersible pump with a shaft line on sliding bearings, consisting of a pump housing located in a tank with a pumped medium, an impeller with vanes interacting with the pumped medium, a shaft line representing a series connection of shafts mounted on sliding bearings in the lower and upper suspensions and seal housing, outlet, base plate, characterized in that the pumped medium under pressure created by the pump is supplied to the internal cavity of the pump, enters the gaps I am waiting for the sleeve and liner of the sliding bearings, providing their washing, lubrication and cooling, after which it is discharged through the collectors to the reduced pressure region through a device that determines the flow rate of the pumped medium through the sliding bearing. 2. Полупогружной насос с валопроводом на подшипниках скольжения по п. 1, отличающийся тем, что перекачиваемая среда перед поступлением во внутренние полости предварительно очищается от механических примесей.2. A semi-submersible pump with a shaft line on sliding bearings according to claim 1, characterized in that the pumped medium is first cleaned of mechanical impurities before entering the internal cavities.
