Выберите грязевой насос для борьбы с наводнениями, учитывая требования к притоку, напору, мусору, заполнению, времени работы, развертыванию, нагнетанию и аварийному резерву.
Диагностика засорения всасывающего патрубка насоса с использованием данных о давлении и расходе, безопасной изоляции, проверки на наличие засоров, проверок на утечку воздуха и превентивных мер.
Планирование технического обслуживания погружного насоса с использованием тенденций состояния, безопасного демонтажа, электрических испытаний, проверки на износ, элементов управления и данных повторного ввода в эксплуатацию.
A jockey pump controller automatically starts and stops the pressure-maintenance pump so small leaks and normal pressure loss do not start the main fire pump. Its settings must coordinate with the fire pump controller, pressure-sensing line, pump curve, system pressure, and adopted fire-protection requirements. The jockey pump should start before the main fire pump and stop after pressure recovers, while the main fire pump's automatic-start behavior remains protected. Final settings and wiring require the approved design, listed controller data, responsible engineer, and...
A fire pump relief valve can refer to a small casing relief valve that prevents pressure buildup from heat when a pump runs at little or no flow, or a larger main pressure relief valve used only where the approved fire-protection design requires it. These devices are not interchangeable. Selection and settings must follow the adopted fire code and standard, the authority having jurisdiction, the listed equipment data, pump curve, driver behavior, and the system pressure limits. A relief valve must never...
Поймите устройство консольных насосов и выбирайте их, используя рабочую точку, характеристику системы, условия всасывания, материалы, электродвигатель, данные по центровке и пусконаладке.
A submersible dewatering pump is selected by matching the required drawdown flow, total dynamic head, solids and abrasiveness, minimum operating depth, cable and power supply, and the site's duty cycle. It should not be chosen from outlet size or motor power alone. Establish how fast water enters, where it can legally discharge, and how the water level and hose route will change. Then plot normal and worst-case duties on a certified pump curve, verify motor loading and cooling, and specify level controls,...
