Abstract
The utility model relates to a flow indicator and an improvement to structure of the flow indicator structure. The flow indicator provided by the utility model is simple in structure, convenient for processing and low in defective rate. The flow indicator comprises a pipe body, wherein an upper end cover is arranged at an upper opening of the pipe body, a lower end cover is arranged at a lower opening, a rotating shaft provided with impellers is arranged between the upper end cover and the lower end cover, and corresponding to the impellers, one side of the pipe body is provided with an inlet pipe, and the other side of the pipe body is provided with an outlet pipe.
Description
Technical field
The utility model relates to a kind of improvement of flow director structure.
Background technology
Flow director is applied in the rotary machine, particularly carries the rotary machine of high-temperature medium.Its bearing body and support section and an axle envelope place all need to carry out cooling processing, and the effective means of its disposal route is water cooling.This just need judge whether water flows by flow director in airtight pipe system.
The main part housing of existing flow director adopts casting to process.Its product exists following deficiency: 1, complex structure.
2, foundry goods contaminated environment, product surface is rough.
3, the casting process instability is prone to sand holes, and rejection rate is higher.
Summary of the invention
The utility model is exactly at the problems referred to above, and a kind of simple in structure, easy to process, flow director that rejection rate is low is provided.
For reaching above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, and the utility model comprises body, and upper shed place of its structural feature body is provided with upper end cover, lower opening is provided with bottom end cover, and the rotating shaft with impeller is set between upper end cover and the bottom end cover; The both sides of body are respectively arranged with inlet tube and outlet corresponding to impeller.
The beneficial effects of the utility model: 1, simple in structure, easy to process, production cost is low: member of the present utility model is few, and is simple in structure; And the utility model can push body by oil press, makes body, inlet tube and outlet one-body molded, can finish by simple machining again, and the utility model is easy to process thus; In addition, the mould of body of the present utility model also is very easy to processing, and engine lathe, drilling machine can be realized; The mould of producing can be produced hundreds of thousands spare the utility model, has reached small investment, many, the cost-effective purposes of output.
2, smooth surface, rejection rate are low: because design feature of the present utility model, can produce by extrusion modling and simple machining, avoided existing flow director behind casting rough, be prone to quality problems such as sand holes, reduced rejection rate.
3, owing to adopted extrusion modling and simple machining, so the deleterious effect that environment has been produced when also having avoided casting has alleviated environmental pollution.

In the accompanying drawing 1 be bottom end cover, 2 for body, 3 for inlet tube, 4 for outlet, 5 for impeller, 6 for rotating shaft, 7 for upper end cover, 8 for projection, 9 for the hole.
Embodiment
The utility model comprises body 2, and upper shed place of body 2 is provided with upper end cover 7, and lower opening is provided with bottom end cover 1, and the rotating shaft 6 with impeller 5 is set between upper end cover 7 and the bottom end cover 1; The both sides of body 2 are respectively arranged with inlet tube 3 and outlet 4 corresponding to impeller 5.
Described upper end cover 7 and/or bottom end cover 1 are made for the clear glass steel; Be convenient to observe the rotation situation of impeller 5 in the body 2.
Described body 2, inlet tube 3 and outlet 4 adopt one-body molded the making of Q235 carbon steel; Adopt prevailing Q235 carbon steel to produce the utility model, compare, saved production cost greatly with the flow director that existing cast copper material is made, and one-body molded, easy to process by extruding.
Below in conjunction with description of drawings process of the present utility model: at first body 2 is positioned in the mould, forms protruding 8(as shown in Figure 3 through body 2 both sides, pressing machine extruding back), on the projection 8 of body 2 both sides, hole (as shown in Figure 4) again; Then the edge in hole 9 is outwards routed up, formed inlet tube 3 and outlet 4(as shown in Figure 5); At last, in inlet tube 3 and outlet 4, process screw thread again, so that be connected with other pipelines.
