Abstract

The utility model relates to a technology of a water inlet and outlet device for a two-direction pump station, which comprises a water inlet pipe, a water outlet pipe, a water guide cone matched with the water outlet pipe, wherein, the water inlet pipe and the water outlet pipe are arranged at the two sides of a water pump, the cross sections of the water inlet pipe and the water outlet pipe form an oblateness shape, and the distance between two ends which are parallel with the directions of an inlet and an outlet flow paths is longer than the distance between the two ends which are vertical with the inlet and the outlet flow paths. The water flow power loss of the two-direction water inlet and outlet form is small, the rotary energy of the outlet of a guide blade can be effectively recovered, the flow velocity is uniformly distributed, the width of each flow path is small, a two-direction pumping function can be realized, and the efficiency of a pumping station can be improved.

Description

Two-way pumping plant water inlet and outlet device

Technical field

The utility model relates to a kind of technical field of two-way pumping plant water inlet and outlet.

Background technique

In the pumping plant of hydraulic engineering was built, people built square water-in and water-out runner in the both sides of suction pump.The circle water inlet oviduct that is arranged in import of water pump impeller one side is arranged in the water inlet flow channel, is arranged in the outlet passage being arranged in the circular water outlet oviduct that water pump vane exports a side, and at the circular water-output water-guide cone of water pump cover upper support.When drawing water, current are through water inlet oviduct, impeller, by guiding outlet passage between water-output water-guide cone and the water outlet oviduct.Though this design reaches the purpose of drawing water, the water outlet width is bigger, needs to drop into than the multiple-project fund, causes unnecessary human and material resources, land wastage.

Technological scheme

The utility model purpose is to design a kind of two-way pumping plant water inlet and outlet device that economizes on resources.

The utility model comprises the intake pipe, outlet pipe and the cooperation that are arranged on the water pump both sides and the water-output water-guide cone of outlet pipe, intake pipe, outlet pipe section are flat circle shape, are parallel to into and out of runner direction two ends distance perpendicular to the two ends distance into and out of the runner direction.

Simultaneously, water-output water-guide cone is flat circle shape, and the two ends distance that is parallel to turnover runner direction is perpendicular to the two ends distance into and out of the runner direction.

Feature of the present utility model is that into water adopts the flat oviduct, the structural type that effluent adopting flat oviduct and water guide cone are used, this two-way water inlet and outlet form flow dynamic loss is little, effectively reclaim the rotating energy of stator outlet, velocity flow profile is even, and width of flow path is little, can realize two-way pumping function, and can improve efficiency of pumping station.Compare with common bricklaying pump and open type pumping plant form, have the following advantages:

(1) obviously reduces the water inlet and outlet width, save the pump station engineering investment;

(2) velocity flow profile is even, pipeline and unit efficiency height;

(3) operation management facility must not change pump body structure and can realize that different direction draws water.Therefore be with a wide range of applications.

Specific embodiment

The horn-like intake pipe 2 of flat is arranged in the import of water pump vane 3, and intake pipe 2 connects and casing 8, and is positioned at water inlet flow channel 1.

The horn-like outlet pipe 4 of flat is arranged in the outlet of water pump vane 3, and connection and casing 8, and is positioned at outlet passage 7.

It is longer that two ends distance on the intake pipe 2 same sections is parallel to water inlet flow channel 1 direction, and perpendicular to water inlet flow channel, direction is shorter.

Outlet pipe 4 also is provided with equally.

Water outlet starting taper 5 is nested with in the same way in outlet pipe 4, and two ends are fixed by pump cover 6 and stent support respectively.

Claims

1, two-way pumping plant water inlet and outlet device, comprise the intake pipe, outlet pipe and the cooperation that are arranged on the water pump both sides and the water-output water-guide cone of outlet pipe, it is characterized in that, intake pipe, outlet pipe section are flat circle shape, are parallel to into and out of runner direction two ends distance perpendicular to the two ends distance into and out of the runner direction.

2, according to the described device of claim 1, it is characterized in that water-output water-guide cone is flat circle shape, the two ends distance that is parallel to turnover runner direction is perpendicular to the two ends distance into and out of the runner direction.
