Abstract
The utility model relates to a difference frequency electric field detector of lubricant metal impurities. When the lubricant metal impurities in a lubricant pool are detected to reach certain degree, the induction of an oscillating coil is changed, the oscillating frequency of a detection oscillator is changed, the change is displayed through a display alarm through segmentation of a difference frequency digital sectionalizer and then is alarmed, and the quality of a lubricant is analyzed.
Description
Technical field
The utility model is a kind of lubricant oil metal impurity difference frequency electric field detector in the detection technique field; Reach one regularly through the lubricant oil metal impurity in the machine oil pond; The inductance of concussion coil changes, thereby the concussion frequency that detects oscillator is also changed, and the segmentation through difference frequency numeral sectionaliser shows from display alarm; And report to the police, and then understand the quality situation of lubricating oil.
Background technology
At present common scale is not detect lubricants performance, can only detection of engine lubricating oil what, can not see any parameter of relevant lubricating oil.
The utility model content
The purpose of the utility model provides a kind of lubricant oil metal impurity difference frequency electric field detector, produces the concussion frequency of a benchmark inconvenience through the benchmark oscillator, delivers in the difference frequency numeral sectionaliser, understands the quality situation of lubricating oil.
Its objective is such realization, among Fig. 1, a kind of lubricant oil metal impurity difference frequency electric field detector is by machine oil pond, concussion coil, detect oscillator, benchmark oscillator, difference frequency numeral sectionaliser, display alarm and form; The concussion coil is put into the machine oil pond, detects oscillator and is connected with the concussion coil electric, and the benchmark oscillator is electrically connected with detection oscillator, difference frequency numeral sectionaliser, and difference frequency numeral sectionaliser and display alarm are electrically connected.
Produce the concussion frequency of a benchmark inconvenience through the benchmark oscillator; Deliver in the difference frequency numeral sectionaliser, detect oscillator simultaneously and also produce a frequency signal the same, also deliver in the difference frequency numeral sectionaliser with the benchmark oscillator with the concussion loop that the concussion coil forms; Lubricant oil metal impurity in being placed on the machine oil pond reaches one regularly; The inductance of concussion coil changes, thereby the concussion frequency that detects oscillator is also changed, and the segmentation through difference frequency numeral sectionaliser shows from display alarm; And report to the police, and then understand the quality situation of lubricating oil.
Description of drawings
The concrete structure of the utility model is provided by following examples and accompanying drawing:
Fig. 1, be a kind of lubricant oil metal impurity of the utility model difference frequency electric field detector configuration diagram.
Among Fig. 1,1, the machine oil pond, 2, the concussion coil, 3, detect oscillator, 4, the benchmark oscillator, 5, difference frequency numeral sectionaliser, 6, display alarm.
Embodiment
