Abstract

Диафрагменный насос содержит камеру перемещения, содержащую рабочую жидкость, и рабочую камеру для перекачиваемой жидкости. Соединительный узел содержит поршень, проходящий в камеру перемещения. Диафрагма соединена с соединительным узлом и разделяет камеру перемещения и рабочую камеру. Приспособление для защиты от перепада давления установлено на соединительном узле и выполнено так, что оно плотно прижимается к камере перемещения, когда перепад давления, в том числе обратный перепад давления, на диафрагме превышает заданное значение. Приспособление для защиты от перепада давления находится между поршнем и диафрагмой и поддерживает диафрагму при избыточном перепаде давления на диафрагме.
