Abstract

Настоящее изобретение относится к насосам, содержащим средство частотно-регулируемого привода, и к способам работы таких насосов. Предложенный способ работы насоса (1) содержит этапы, на которых получают величины рабочих параметров насоса (1), указывающие состояния насоса, передают упомянутые величины рабочих параметров из средства (2) частотно-регулируемого привода в устройство (11) управления, определяют, выполняется ли заданное условие, на основании выполнения упомянутого заданного условия передают инструкции из устройства (11) управления в средство (2) частотно-регулируемого привода. Кроме того, предложены компьютерный программный продукт, загружаемый в память цифрового вычислительного устройства, который включает в себя части программного кода для выполнения заявленного способа, насос (1), насосная система и устройство (11) управления для насоса.The present invention relates to pumps comprising variable frequency drive means and methods for operating such pumps. The proposed method of operation of the pump (1) contains the stages at which the values of the operating parameters of the pump (1) are obtained, indicating the states of the pump, the mentioned values of the operating parameters are transmitted from the means (2) of the variable frequency drive to the control device (11), it is determined whether predetermined condition, based on the fulfillment of said predetermined condition, instructions are transmitted from the control device (11) to the variable frequency drive means (2). In addition, the proposed computer program product loaded into the memory of a digital computing device, which includes parts of the program code for performing the claimed method, a pump (1), a pumping system and a control device (11) for the pump.
