Abstract
The utility model relates to a double-plane electric capacity type sensor with an upper and a lower plane electric capacitors and a closed inner cavity for testing the quality of lubricating oil. The utility model comprises a closed inner cavity; the upper and the lower surfaces of the inner cavity are two plane electric capacitors, and the surface of each plane electric capacitor comprises two mutually parallel and mutually exclusive metal wires which are arranged circumambiently, or two sets of mutually exclusive metal wires which are arranged in parallel; accordingly, the dielectric constant of lubricating oil can be detected on line, and the purpose of detecting the quality of the lubricating oil can be obtained.
Description
The utility model belongs to sensor technical field, further relates to a kind of closed inner chamber biplane condenser type quality of lubrication oil detecting sensor of two planar capacitors up and down that has.
Lubricating oil in the machine lubricating system in use because effects such as high temperature, extreme pressure or pollutions, the quality of self plays variation, thereby has influence on original greasy property.And the variation of the specific inductive capacity of lubricating oil often can combined reaction lubricating oil physics and the variation of chemical property.By measuring the variation of lubricating oil specific inductive capacity, can reach the purpose that detects quality of lubrication oil.Quality of lubrication oil detector in the past all adopts the monoplane capacitor as sensor.The shortcoming of this kind sensor is to be merely able to use at the laboratory off-line, does not use in the engine oil road and do not have enough to be installed in, and does not also pick the factor that quality of lubrication oil changes that influences of distinguishing.
The purpose of this utility model is to provide a kind of enclosed cavity that places, and is made up of two planar capacitors up and down, can onlinely be installed in the quality of lubrication oil detecting sensor in the machine lubricating system pipeline.
The utility model comprises a closed inner chamber, the inner chamber upper and lower surface is two planar capacitors, and every planar capacitor is by being arranged in two parallel to each other, mutually disjoint metal wires on the non-metal base plate around arranging or two groups of metal wires that mutually disjoint are arranged in parallel and form capacitor.
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is the utility model one-piece construction synoptic diagram.
Fig. 3 is the utility model planar capacitor embodiment 1 structural drawing.
Fig. 4 is the utility model planar capacitor embodiment 2 structural drawing.
The utility model is by cavity 1, and last planar capacitor 2 and lower plane capacitor 3 are formed.Last planar capacitor 2 places plane on the cavity 1; Lower plane capacitor 3 places cavity 1 lower plane.Cavity 1 and last plane capacitance suitable 2 and lower plane capacitor 3 are formed the envelope inner chambers.The planar capacitor of going up planar capacitor 2 and lower plane capacitor 3 down partly occupy the interior survey of closed inner chamber.Cavity 1 two ends are can be for the screw thread that inserts lubricating pipe.Lubricating oil is on cavity 1 between plane capacitance 2 and the lower plane electric capacity 3 time, the material that quality such as the metallic particles that the variation of the specific inductive capacity of bottom lubricating oil mainly is subjected to comprise in the lubricating oil in the cavity 1, water and proportion are bigger than lubricating oil sinks to influencing, the variation of the specific inductive capacity of cavity 1 internal upper part lubricating oil then mainly is subjected to the lubricating oil pH-value, the influence of indexs such as viscosity.Like this, both can distinguish the factor that influences the lubricating oil change in dielectric constant, also can when oil stream constantly passes through cavity 1, detect the relative variation of lubricating oil specific inductive capacity, to determine the variation of quality of lubrication oil situation.
Fig. 3 is the utility model planar capacitor embodiment 1 structural drawing, and it has represented to go up among Fig. 1 a kind of structure of planar capacitor 2 and lower plane capacitor 3.On a plane of nonmetallic materials substrate 4, arrange two metal line 5, arrangement form as shown in Figure 2, two light from the center, two lines are parallel to each other, mutually disjoint, and linearly reach right angle folding around center arrangement.
Fig. 4 is the utility model planar capacitor embodiment 2 structural drawing.It has represented to go up among Fig. 1 the another kind of structure of planar capacitor 2 and lower plane capacitor 3.On a plane of nonmetallic materials substrate 6, arrange two groups of metal wires, arrangement form as shown in Figure 3, every group of line is communicated with voluntarily, non-intersect with another group line, the major part of two groups of lines is layout parallel to each other.
The utility model is by online detection lubricating oil specific inductive capacity and then reach that to detect lubricating quality be purpose, and being applied to this utility model is in the measuring instrument device of the online detection quality of lubrication oil that constitutes of sensor.
Description of drawings:
Fig. 2 is that A-A of the present utility model digs view.
