The utility model aims to solve the technical problems that: a main drain pump jet device convenient to install and maintain is provided to solve the problems in the prior art.
The technical scheme adopted by the utility model is as follows: the main drainage pump jet device comprises a reducing pipe, an elbow pipe, a jet nozzle, a connecting nut, a flange, a mixing chamber, a neck and a diffusion pipe, wherein the reducing pipe is in threaded connection with the elbow pipe, and the neck is in threaded connection with the mixing chamber; the neck finish is of a telescoping length.
Preferably, the neck is formed by detachably connecting more than one neck units.
Preferably, two adjacent neck units are connected by screw threads.
Preferably, the number of the reducing pipes is more than 2, the lengths of the reducing pipes are sequentially increased, and the radiuses of one end, connected with the elbow, of all the reducing pipes are the same.
The utility model has the beneficial effects that:
1. compared with the prior art, the utility model can select reducing pipes with different lengths according to actual conditions, and the number of neck units is selected for field assembly according to actual conditions, the reducing pipes and the neck units are shortened to different degrees according to actual requirements, the overall longitudinal dimension and the transverse dimension of the assembled jet device are shortened to different degrees according to actual requirements, and the assembled jet device is convenient to integrally transport in a threaded connection mode, has high flexibility and easy installation, can be completed by 1 servicer during replacement and damage of the jet device, effectively improves the man-hour utilization of the servicer, and saves labor and material cost by about 1-2 ten thousands yuan/year; the replacement and installation time of the jet device is greatly shortened.
2. Compared with the prior art, the utility model shortens the length of the neck, can reduce the water flow resistance, and the venturi tube formed by the mixing chamber, the neck and the diffusion tube is more sensitive to flow increase fluctuation reaction, and the steady flow is started more timely.
Drawings
FIG. 1 is a schematic diagram of the overall structure of a conventional fluidic device;
fig. 2 is a schematic diagram of the overall structure of the present utility model.
Detailed Description
The utility model will be further described with reference to the accompanying drawings and specific examples.
Reference numerals in the drawings of the specification include: reducing pipe 1, elbow pipe 2, jet nozzle 3, connecting nut 4, flange 5, mixing chamber 6, neck 7, and diffuser 8.
Example 1:
the prior jet device, as shown in fig. 1, comprises a reducing pipe 1, an elbow pipe 2, a jet nozzle 3, a connecting nut 4, a flange 5, a mixing chamber 6, a neck 7 and a diffusion pipe 8, wherein the reducing pipe 1 is welded at the lower port part of the elbow pipe 2, the mixing chamber 6, the neck 7 and the diffusion pipe 8 are sequentially fixed at the right port part of the elbow pipe 2 from left to right, the mixing chamber 6 is connected with the elbow pipe 2 through the flange 5, and the jet nozzle 3 is connected at the left upper end of the elbow pipe 2 through the connecting nut 4 in a threaded manner.
The dimension between the lower end of the reducing pipe 1 of the existing jet device and the axis of the horizontal section of the bent pipe 2 is 740mm.
The size between the lower end opening part of the elbow pipe 2 and the axis of the horizontal section of the elbow pipe 2 is 120mm, the size of the reducing pipe 1 is 620mm, the size between the axis of the vertical section of the elbow pipe 2 and the right end of the jet nozzle 3 is 75mm, the distance between the right end of the jet nozzle 3 and the right end of the elbow pipe 2 is 20mm, and the size between the left end of the mixing chamber 6 and the right end of the diffusion pipe 8 is 830mm. The overall longitudinal dimension of the assembled jet device is 740mm, and the transverse dimension is 925mm.
The main drain pump fluidic device that easy to assemble and maintain, as shown in fig. 2, differs from the existing fluidic devices in that: the length of the reducing pipes 1 is smaller than 620mm in advance, the lengths of the reducing pipes 1 are sequentially reduced, the lengths of the reducing pipes 1 can be set according to practical situations, the reducing pipe 1 with the length of 220mm is selected, the whole size of the reducing pipe 1 is shortened to 220mm from the original length of 620mm, the sizes of the upper end opening and the lower end opening of the reducing pipe 1 are unchanged, in the embodiment, the length of one neck opening 7 unit is 120mm, the length of one neck opening unit is 60mm, in the embodiment, two neck opening units are adopted to be assembled into the neck opening 7, the length of the neck opening 7 is shortened to 120mm from the original length of 620mm, the reducing pipe 1 is in threaded connection with the bent pipe 2, and the neck opening 7 is in threaded connection with the mixing chamber 6. The overall longitudinal dimension of the assembled jet device is reduced from 740mm to 340mm, and the transverse dimension is reduced from 925mm to 425mm.
Through adopting first district, adopting two district underground main drain pump room practical application in certain ore deposit, this main drain pump fluidic device's work effect is good.
