Abstract
The invention discloses an air vent structure preventing oil overflow. The air vent structure preventing oil overflow comprises an air vent formed in the top of a centrifugal pump, the air vent is provided with a vertical air pipe, a top cap is arranged at the top end of the air pipe, an air hole is formed between the top cap and the top end of the air pipe, and the length of the air pipe is larger than 5 cm. Due to the fact that the air pipe is high, lubricating oil cannot reach the height easily, and lubricating oil is effectively prevented from being sprayed to the outside of the centrifugal pump.
Description
Technical field
The application relates to a kind of breather hole structure, specifically, relates to a kind of breather hole structure preventing oil spilling.
Background technique
Centrifugal pump has vertical, horizontal, single-stage, multistage, single suction, double suction, the various ways such as self-priming.Centrifugal pump utilizes vane rotary and makes water generation centrifugal motion carry out work.Before activation, must make to be full of water in pump case and suction sleeve, then starting electrical machinery, make pump shaft impeller and water do high speed rotary motion, water generation centrifugal motion, is thrown toward impeller outer edge to water pump, and the runner through volute pump case flows into the setting-out pipeline of water pump.
Add lubricant oil in centrifugal pump to lubricate, need to arrange air hole to breathe freely at the top of centrifugal pump, but due to the rotation of centrifugal pump; lubricant oil often can be emerged from air hole position; the outside of centrifugal pump is stained with lubricant oil, is difficult to cleaning, and needs frequent make-up oil.
Application content
The application overcomes shortcoming of the prior art, provides a kind of breather hole structure preventing oil spilling, and it effectively avoids lubricant oil to be sprayed at centrifugal pump outside, keeps centrifugal pump neat and tidy, does not need frequent make-up oil, time saving and energy saving.
In order to solve the problems of the technologies described above, the application is achieved through the following technical solutions:
Prevent a breather hole structure for oil spilling, comprise the air hole being arranged at centrifugal pump top, described air hole is provided with vertical tracheae, and crown cap is established on described tracheae top, is provided with pore between described top cap and tracheae top, and the length of described tracheae is greater than 5 centimetres.
Further, described tracheae is provided with annular swab case.
Further, described annular swab case is provided with oil well pump, and the bottom of described oil well pump connects the inside of described centrifugal pump.
Further, described annular swab case is provided with filter screen.
Further, described annular swab case is provided with and detachably receives oil box.
Further, described tracheae is provided with the recess for placing adsorption paper near cap position, described top.
Further, described pipe is provided with support, and described support is provided with threaded piece, and described top cap and described threaded piece are spirally connected.
Compared with prior art, the beneficial effect of the application is:
A kind of breather hole structure preventing oil spilling described in the application, comprise the air hole being arranged at centrifugal pump top, air hole is provided with vertical tracheae, crown cap is established on tracheae top, be provided with pore between top cap and tracheae top, the length of tracheae is greater than 5 centimetres, because tracheae is higher, lubricant oil is difficult to reach this height, effectively avoids lubricant oil to be sprayed at centrifugal pump outside.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present application, is used from explanation the application, does not form the restriction to the application with the embodiment one of the application, in the accompanying drawings:
Fig. 1 is a kind of schematic diagram preventing the breather hole structure of oil spilling described in the application.
In figure, 1---centrifugal pump; 2---air hole;
3---tracheae; 4---top cap;
5---pore; 6---recess;
7---annular swab case.
Embodiment
Be described below in conjunction with the preferred embodiment of accompanying drawing to the application, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the application, and be not used in restriction the application.
Embodiment 1:
As shown in Figure 1, a kind of breather hole structure preventing oil spilling described in the application, comprise the air hole 2 being arranged at centrifugal pump 1 top, air hole 2 is provided with vertical tracheae 3, and crown cap 4 is established on tracheae 3 top, is provided with pore 5 between top cap 4 and tracheae 3 top, the length of tracheae 3 is 10 centimetres, because tracheae 3 is higher, lubricant oil is difficult to reach this height, effectively avoids lubricant oil to be sprayed at centrifugal pump 1 outside.
Meanwhile, sometimes because centrifugal pump 1 rotating speed is too fast, still have lubricant oil and overflow, tracheae 3 outside is provided with annular swab case 7, and annular swab case 7 is provided with detachably receives oil box, when receiving too much lubricant oil in detachable receipts oil box, can pull down and outwell.
Tracheae 3 is provided with the recess 6 for placing adsorption paper near cap 4 position, top, posts adsorption paper, is sopped up by the lubricant oil of spilling, prevent lubricating oil viscosity on tracheae 3 in recess 6.
Tracheae 3 inside is provided with support, and support is provided with threaded piece, and top cap 4 and threaded piece are spirally connected, and can rotate the position regulating top cap 4 and threaded piece, adjust the size of pore 5.
Embodiment 2:
The present embodiment is substantially identical with embodiment 1 technological scheme, and something in common repeats no more, and its difference is:
Annular swab case 7 is provided with filter screen, and filter out the foreign material in lubricant oil, annular swab case 7 is provided with oil well pump, and the bottom of oil well pump connects the inside of centrifugal pump 1, lubricant oil is extracted into centrifugal pump 1 inner, again uses.
Last it is noted that these are only the preferred embodiment of the application; be not limited to the application; although with reference to embodiment to present application has been detailed description; for a person skilled in the art; it still can be modified to the technological scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; but within all spirit in the application and principle; any amendment of doing, equivalent replacement, improvement etc., within the protection domain that all should be included in the application.
