Abstract
The utility model provides a submersible motor inner cavity gas tightness detection device, and belongs to the electromechanical equipment detection device technology field. The novel detection device can solve problems that the prior submersible motor inner cavity air tightness detection device is complex in structure and troublesome in operation. The submersible motor inner cavity gas tightness detection device includes a body which is provided with a cavity and a pressure gauge. The body is provided with a gas inlet, a gas outlet, and a testing mouth which are communicated with one another. The gas inlet is used for enabling gas with a certain pressure to enter, and the gas outlet is communicated with an inner cavity of a motor. The testing mouth is connected the pressure gauge which can detect the gas tightness of the inner cavity of the motor. The detection device is simple in structure and is easy to operate.
Description
Technical field
The utility model belongs to the detection technique field of electromechanical equipment, has related to a kind of pick-up unit of electromechanical equipment, has particularly related to the bubble-tight pick-up unit of a kind of submersible motor inner chamber.
Background technology
At present enterprise to the motor cavity of submersible pump airtight test generally adopt the air pressure test, the submersible motor complete machine is submerged, inject the gas of certain pressure, check whether motor cavity leaks gas, when submersible motor because assembling improper or mechanical seal when losing efficacy, this test operation often is easy to the water of experimental tank is immersed motor cavity, makes the damage of making moist of motor lines bag; The submersible motor submerging test must all pull the plug submersible motor simultaneously, and complex operation is time-consuming often.
Summary of the invention
There are the problems referred to above in the utility model for existing technology, has proposed a kind of simple in structure, easy to operate bubble-tight pick-up unit of submersible motor inner chamber.
The utility model is realized by following technical proposal: the bubble-tight pick-up unit of a kind of submersible motor inner chamber, comprise body and pressure device with cavity, it is characterized in that, have the air intake opening, gas outlet, the test port that are interconnected on the described body, described air intake opening is used for passing into the gas of certain pressure, described gas outlet is used for being communicated with motor cavity, is connected with for detection of the bubble-tight pressure device of motor cavity at described test port place.
When submersible motor inner chamber leakproofness is tested, the gas outlet is communicated with the submersible motor inner chamber, inject the gas of certain pressure by air intake opening, after observation tensimeter pointer reaches requirement, stop air intake opening being passed into gas, and be sealed into gas port, the pressurize certain hour; If within the dwell time of regulation, it is stable that the tensimeter pointer keeps, and then the submersible motor inner chamber is air tight; If the tensimeter pointer descends, then submersible motor inner chamber gas leakage, the bubble-tight structure of the detecting device of this submersible motor inner chamber is simple, and is easy and simple to handle, reduced the whole water-immersed loaded down with trivial details operation of submersible motor.
In the above-mentioned bubble-tight pick-up unit of a kind of submersible motor inner chamber, described pressure device is tensimeter.
In the above-mentioned bubble-tight pick-up unit of a kind of submersible motor inner chamber, described body is the integral type structure, and described body middle part is cylindric.Adopt integral structure, impermeability is better.Being the cylindric testing staff of convenience in the middle part of when detecting grasps.
In the above-mentioned bubble-tight pick-up unit of a kind of submersible motor inner chamber, described gas outlet and described test port place are fixed with O-ring seal.
In the above-mentioned bubble-tight pick-up unit of a kind of submersible motor inner chamber, be provided with breather cheek valve at the air intake opening place of described body.When stopping that air intake opening passed into gas, need to seal air intake opening, and it is obviously convenient than being sealed into gas port at air intake opening breather cheek valve to be set.
Compared with prior art, the bubble-tight pick-up unit of this submersible motor inner chamber can be directly being connected by gas outlet and motor cavity, in testing process, only need to pass into to air intake opening the gas of certain pressure, and directly the number of degrees of visual observations pressure device determine to have advantages of the impermeability of motor cavity simple in structure, easy to operate.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1, body 2, air intake opening 3, gas outlet; 4, test port; 5, pressure device; 6, breather cheek valve 7, O-ring seal; 8, motor cavity.
Embodiment
Below be specific embodiment of the utility model, and by reference to the accompanying drawings the technical solution of the utility model be further described, but the utility model is not limited to these embodiment.
The bubble-tight pick-up unit of a kind of submersible motor inner chamber as shown in Figure 1, comprise body 1 and pressure device with cavity, have the air intake opening 2, gas outlet 3, the test port 4 that are interconnected on the described body 1, described air intake opening 2 is used for passing into the gas of certain pressure, described gas outlet 3 is used for being communicated with motor cavity 8, is connected with for detection of motor cavity 8 bubble-tight pressure devices at described test port 4 places.In the present embodiment, this pressure device is tensimeter 5.
Body 1 is the integral type structure, and described body 1 middle part is cylindric.Body 1 adopts integral structure, and impermeability is better; Being the cylindric testing staff of convenience in the middle part of when detecting grasps.The impermeability of pick-up unit when detecting in order to improve, in the gas outlet 3 and test port 4 places be fixed with O-ring seal 7, sealing circle 7 can adopt elastomeric material to make.Air intake opening 2 places at body 1 are provided with breather cheek valve 7, when stopping that air intake opening 2 passed into gas, need to be to air inlet, and 2 seal, and it is obviously convenient than being sealed into gas port 2 at air intake opening 2 breather cheek valve 7 to be set.
This pick-up unit can deadly be worked like this, when submersible motor inner chamber leakproofness is tested, gas outlet 3 is communicated with submersible motor inner chamber 8, inject the gas of certain pressure by air intake opening 2, after observation tensimeter 5 pointers reach requirement, stop air intake opening 2 is passed into gas, this moment, breather cheek valve 7 was closed air intake opening 2, then the pressurize certain hour; If within the dwell time of regulation, it is stable that tensimeter 5 pointers keep, and then submersible motor inner chamber 8 is air tight; If the tensimeter pointer descends, then submersible motor inner chamber 8 gas leakage, the bubble-tight structure of the detecting device of this submersible motor inner chamber is simple, and is easy and simple to handle, reduced the whole water-immersed loaded down with trivial details operation of submersible motor.
Specific embodiment described herein only is to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has more used the terms such as body 1, air intake opening 2, gas outlet 3, test port 4, pressure device 5, breather cheek valve 6, O-ring seal 7, motor cavity 8, do not get rid of the possibility of using other term.Using these terms only is in order to describe more easily and explain essence of the present utility model; They are construed to any additional restriction all is contrary with the utility model spirit.
