Description

Изобретение относится к насосостроению, в частности к конструкции входного устройства насоса, и может быть исполь-зовано при проектировании гидротранспортных установок для про₍мышленности И сельского хозяйства. 5 Известно входное устройство насоса, содержащее приспособление для ор.ганизации потока, выполненное в виде емкости и размещенного по ее оси сопла [1]. '10The invention relates to a pump engineering, in particular to the input of the pump device design and can be ispol'uet-Call when designing systems for hydro-pro _(thinking and agriculture. 5 is known pump inlet device comprising a fixture for or.ganizatsii stream formed in a container and placed along its axis nozzle [1].

Недостаток указанного входного устройства - сложность конструкции.The disadvantage of this input device is the design complexity.

Наиболее близким к предлагаемому по технической сущности является вход· ное устройство насоса, содержащее со-15 общенную с всасывающим патрубком насоса вертикальную емкость с поплавком’ [2].Closest to the proposed technical essence is the inlet · pump device, containing co-15 shared with the suction pipe of the pump vertical tank with a float ’[2].

Недостатками известного входного устройства насоса является сложность изготовления и эксплуатации при боль-^мших габаритах емкости.Disadvantages of the known pump input device is the complexity of manufacture and operation at larger capacity ^m Shih dimensions.

Цель изобретения - упрощение изготовления и эксплуатации.The purpose of the invention is the simplification of manufacture and operation.

Поставленная цель достигается тем, что во входном устройстве насоса, со- держащем сообщенную с всасывающим патрубком насоса вертикальную емкость; с поплавком, емкость снабжена по меньшей мере одним дополнительным поплавком и расположенными в ее верхней 30 части вертикальными направляющими по числу поплавков.This goal is achieved by the fact that in the inlet of the pump, containing a vertical tank communicated with the suction pipe of the pump; with a float, the tank is equipped with at least one additional float and vertical guides located in its upper part 30 according to the number of floats.

Claims

INPUT PUMP DEVICE containing reported c. the suction pipe of the pump has a vertical tank with a float, which is connected with the fact that, in order to simplify the manufacture and operation, the tank is equipped with at least one additional float and vertical guides located in its upper part according to the number of floats.

разрез ny incision? in FIG.

2 is a section AA in FIG. 1.

The pump inlet device comprises a vertical tank 3 connected to the suction pipe 1 of the pump 2 with a float 4. The tank 3 is provided with at least one additional float 5 and vertical guides 6 and 7 located in its upper part according to the number of floats.

The input device of the pump operates as follows.

With the steady state operation of the pump 2, the level of the working medium in the vertical tank 3, and with it the floats 4 and 5 occupy their upper position. In this case, the working medium, through the vertical tank 3 and the suction pipe 1, continuously enters the pump 2. The floats 4 and 5 together with the guides bi 7 stabilize the surface of the working medium in the vertical tank 3.

The floats are small, technologically advanced to manufacture, they can be made from pipes of various profiles (round, square, rectangular and others), less time consuming to control their tightness (less water and time are required for [filling and discharging the float) , For gumming floats do not require special large av-; Toklava. The invention substantially UP- ¹ grows' production and operation. pump input device.
