Description
Изобретение относитс к насосостроению , в частности, к конструк- , ции насосной установки с пневмоаккумул тором , и может быть использовано при проектировании установок дл перекачивани жидкости в промышленности , строительстве и сельском хоз йстве .The invention relates to pump engineering, in particular, to the design of a pump unit with a pneumatic accumulator, and can be used in the design of installations for pumping fluid in industry, construction and agriculture.
Известна насосна установка, содержаща насосный агрегат, пневмоблок и датчик давлени с регул тором 1 .A known pump installation comprising a pump unit, a pneumatic unit and a pressure sensor with a regulator 1.
Недостатком этой насосной установки вл етс грубое, регулирование расхода .The disadvantage of this pumping unit is a coarse flow control.
Наиболее близкой к изобретению вл етс насосна установка, содержаща насосный агрегат и гидропневмоаккумул тор с разделенными эластичной перегородкой пневматической и гидравлической полост ми, последн из которых подключена патрубком к напорной магистрали и датчик-реле давлени системы управлени .Closest to the invention is a pump unit comprising a pump unit and a hydro-pneumatic accumulator with an elastic partition separated by pneumatic and hydraulic cavities, the latter of which is connected by a branch pipe to a pressure line and a pressure sensor relay of the control system.
Недостатком известной установки вл етс мала надежность, что св зано с превышением расчетного давлени в пневматической полости при нагреве- .A disadvantage of the known installation is low reliability, which is associated with an excess of the design pressure in the pneumatic cavity when heated.
Цель изобретени - повышение надежности .The purpose of the invention is to increase reliability.
Поставленна цель достигаетс тем, что датчик реле давлени установлен на патрубке.The goal is achieved by the fact that the pressure switch sensor is installed on the nozzle.
На чертеже показана схеманасосной установки.,The drawing shows the schematic pump installation.,
Насосна установка содержит насосный агрегат 1 и гидропневмоакку10 мул тор 2 с разделенными эластичной перегородкой 3 пневматической и гидравлической полост ми 4 и 5, пЬследн из которых подключена патрубком 6 к напорной магистрали 7, и датчик15 реле 8 давлени систе вд управлени (не показана),- установленный на патрубке 6 манометр 9 и приспособление 10 дл накачки пневматической полости 4.The pumping unit contains a pumping unit 1 and a hydropneumatic package 10 multiplexer 2 with pneumatic and hydraulic cavities 4 and 5 separated by an elastic partition, the foot of which is connected by nozzle 6 to the pressure line 7, and the control unit 15 of pressure control relay 8 (not shown), a pressure gauge 9 mounted on nozzle 6 and a device 10 for pumping pneumatic cavity 4.

Установка работает следующим образом .The installation works as follows.
Вода подаетс насосным агрегатом 1 по напорной магистрали 7 потребителю . На патрубке 6 установлен гид2S ропневмоаккумул тор 2, в котором создано давление воздуха с помощью приспособлени 10 дл накачки воздуха , контролируемое манометром 9.Water is supplied by the pump unit 1 via the pressure line 7 to the consumer. On the nozzle 6, a hydro2S accumulator 2 is installed, in which air pressure is created with the aid of a device 10 for pumping air, controlled by a pressure gauge 9.
