On vacuum mechanical pump observation window be also generally arranged it is smaller, and pump inner engine oil discoloration after be difficult to observe,.
Summary of the invention
The purpose of this utility model is to provide a kind of brackets for gas chromatograph-mass spectrometer vacuum mechanical pump, pass through collecting pump
The machine oil of body leakage, and pump housing leakage oil level is measured, consequently facilitating operator judges whether to need to add machine oil.
To achieve the above object, the utility model is implemented using following technological means：
A kind of bracket for gas chromatograph-mass spectrometer vacuum mechanical pump, including outer framework, graduated vessels, the outer framework packet
Include frame and the lower bracket extended downwardly from upper frame in ring-type；Aperture, aperture lower end are provided at the geometric center of funnel plate
The tubular graduated vessels extended downwardly are provided with, and tubular graduated vessels height is no more than lower bracket height；The funnel plate
It is separably mutually fixed with upper frame by fastener.
In above-mentioned technical proposal, several broken line traces is provided on the funnel plate.
Further, under bracket upright state, the inclination angle of funnel plate and the upright horizontal plane of bracket is 10 ° ~ 30 °.
Further, the funnel plate is transparent.
In above-mentioned technical proposal, the tubular graduated vessels are separable mutually to be fixed with funnel plate.
As a kind of effective embodiment, the upper area of plane of the funnel plate is 80 ~ 200cm2。
As a kind of effective embodiment, the capacity of the tubular graduated vessels is 50-100mL, and tubular scale holds
The diameter of section of device is 1-2.5cm.
The utility model at least has following usefulness：
1. the machine oil of pump housing leakage is collected by funnel plate, water conservancy diversion to tubular graduated vessels, after the collection of a period of time,
This bracket is taken out, mechanical pump lubricating oil leakage situation can be intuitively judged according to scale, convenient for addition machine oil in due course；
2., can by being that can be separated from each other fixed structure between setting outer framework, funnel plate and tubular graduated vessels
Convenient for the cleaning of each component；
3. passing through machine oil color and adhesive capacity on the broken line trace on funnel plate, it can be determined that the shape of pump housing leakage machine oil
State, in order to which operative employee judges whether to need to repair the pump housing；
4. the rationally upper area of plane size of setting funnel plate, can be convenient for the collection to machine oil, and rationally setting tubular is carved
Spend the capacity and diameter of section size of container, can reading to engine oil leakage quantity it is more accurate.
Detailed description of the invention
Fig. 1 is the overlook direction schematic diagram of the utility model；
Fig. 2 is that the utility model looks up direction schematic diagram.
Specific embodiment
In order to be more easily understood the purpose of this utility model, technical solution and advantage, with reference to embodiments, to this
Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain that this is practical new
Type is not used to limit the utility model.
Embodiment
As shown in Figure 1, a kind of bracket for gas chromatograph-mass spectrometer vacuum mechanical pump, including outer framework 2, graduated vessels 3,
Funnel plate 1 is transparent, and the outer framework 2 includes cyclic annular above frame 21 and the lower bracket 22 extended downwardly from upper frame 21；
Under bracket upright state, the inclination angle of funnel plate 1 and the upright horizontal plane of bracket is 10 ° ~ 30 °, the geometric center of funnel plate 1
Place is provided with aperture 11, four broken line traces converged to aperture 11 is provided on funnel plate 1,11 lower end of aperture is provided with to downward
The upper limb of the tubular graduated vessels 3 stretched, tubular graduated vessels 3 mutually screws fixation, and cylinder by spiral lamination and 11 lower end of aperture
3 height of shape graduated vessels is no more than 22 height of lower bracket；The funnel plate 1 by the intermediate plate 12 of lower end, separably with it is upper
21 phase of frame is fixed.
In use, which is placed on to the lower section of vacuum mechanical pump, in gas chromatograph-mass spectrometer use process, if very
There is leakage machine oil phenomenon in empty mechanical pump, and machine oil flow to tubular graduated vessels 3 after dropping to funnel plate 1 and is collected, if vacuum
Mechanical pump is that slightly, when inevitably leaking in the reasonable scope, tubular graduated vessels 3 are collected into a small amount of machine oil, and leak
The machine oil that especially broken line trace is in collection adherency for a long time on strickle 1 changes colour because being long placed in, and can determine whether to be in normal for the pump housing
Working condition；If tubular graduated vessels 3 have been collected into a certain amount of machine oil, and especially broken line trace is in for a long time on funnel plate 1
The machine oil for collecting adherency changes colour because being long placed in, and operator can determine whether to be to need to carry out machine oil supplement state for the pump housing；If tubular is carved
Degree container 3 is collected into a certain amount of machine oil, and when broken line trace and funnel plate 1 are in the machine oil for being stained with more pellucidity, can sentence
Breaking as the pump housing is abnormal leak condition, needs to be repaired in time.
In the present embodiment, the upper area of plane of funnel plate 1 is 80 ~ 200cm2, and the capacity of tubular graduated vessels 3 is set
