Detailed Description
In order that the objects and advantages of the invention will be more clearly understood, the invention will now be described in detail with reference to the following examples. It is to be understood that the following text is merely illustrative of one or more specific embodiments of the invention and does not strictly limit the scope of the invention as specifically claimed.
As shown in figure 2, a supporting dirty dual-purpose pump of dry diving who carries vertical installation, including the pump body 200, the one end setting of the pump body 200 is used for the driving motor who is connected with the pump shaft, and the other end of the pump body 200 is provided with the portion of intaking, and the play water orientation of A delivery port is A direction on the pump body 200, and A direction and pump shaft are arranged perpendicularly, are provided with the B water inlet on the portion of intaking, the B water inlet intake orientation be B direction, B direction and pump shaft are arranged perpendicularly.
Specifically, a sewage discharge structure for discharging sewage is arranged on the water inlet part. The water inlet B and the water outlet A are respectively arranged at two sides of the pump body 200. The pump body 200 comprises a pump case, the water inlet part comprises a bent pipe 100, the water inlet B is formed by a port part of the bent pipe 100, the other end of the bent pipe 100 is communicated with the water inlet A on the pump case, and the water inlet direction of the water inlet A is consistent with the length direction of the pump shaft. The pump housing and elbow 100 are a unitary structure. The elbow 100 is sequentially divided into a1, a2 and A3 pipe sections 113 along the flowing direction of fluid, one side of the elbow 100 close to a driving motor is an A1 side, the other side of the elbow 100 is an A2 side, the A1 pipe section 111 is an arc elbow 100 section, the curvature center of the A1 pipe section 111 is located on the A2 side, the A2 pipe section 112 is an arc elbow 100 section, the curvature center of the A2 pipe section 112 is located on the A1 side, the water outlet direction of the outlet end of the A2 pipe section 112 is perpendicular to the length direction of the pump shaft, the A3 pipe section 113 is an arc pipe section, and the outlet of the A3 pipe section 113 is correspondingly connected with the A1 water inlet on the pump shell.
In detail, the central line of the water inlet B and the central line of the water outlet A are both positioned on a plane A, and the plane A is vertical to the pump shaft. The sewage discharge structure comprises an open-close type sewage discharge outlet 101 arranged on the pipe wall of the side A2. A mounting bracket 120 is provided on the pump housing between the elbow 100 and the outlet a. The drain 101 is provided with a threaded hole, and the opening and closing of the drain 101 are realized through a threaded structure.
According to the invention, the elbow pipe 100 is added to the suction inlet of the original horizontal type dry-submersible dual-purpose pump which is matched with sewage lifting (the pump body 200 and the elbow pipe 100 form a whole), the direction of the suction inlet of the original pump is changed by 90 degrees, and the mounting bracket 120 is welded on one surface of the elbow pipe 100 added to the bottom of the pump body 200 to support the whole dry-submersible dual-purpose pump. The dry-submersible dual-purpose pump matched with the sewage lifting is a channel type sewage pump, the medium is sewage and contains impurity particles (such as sludge, silt, clay, suspended matters and the like) with various sizes, and therefore, after the suction elbow pipe 100 is added, a drainage hole (adopting RP1/2 sealing pipe threads) is arranged at the bottom of the suction elbow pipe so as to facilitate the drainage of sundries blocked in the suction elbow pipe 100 of the pump in the operation process of the sewage lifting equipment and ensure the lifting efficiency of the whole set of equipment.
