Oil granule counter

Abstract

The invention relates to an oil granule counter which comprises an oil sample bottle, a liquid inlet tube, a sample pond, a liquid back tube, a plunger pump and a waste liquid collecting bottle, wherein one end of the liquid inlet tube is inserted into the oil sample bottle; the other end of the liquid inlet tube is connected with one end of the sample pond; the other end of the sample pond is connected with one end of the liquid back tube; the other end of the liquid back tube is inserted into the waste liquid collecting bottle; the plunger pump is arranged between the liquid back tube and the sample pond; a laser emitting device is arranged above the sample pond; a laser shaper is arranged between the laser emitting device and the sample pond; a light sensitive receiver is arranged below the sample pond; the light sensitive receiver is connected with a processor; a corrugated transverse tube is arranged between the liquid inlet tube and the sample pond; the corrugated transverse tube is of a hollow tube structure; wave-shaped bulges are arranged on both the upper surface and the lower surface of the corrugated transverse tube; and the bulges on the upper surface and the bulges on the lower surface are arranged in a staggered manner. The oil granule counter has the beneficial effects of being wide in application range, high in detection precision, simple in structure and convenient to operate, and the problem that a tube is blocked as the tube diameter is reduced to improve the precision is reduced.

Description

technical field [0001] The invention relates to a particle counter, in particular to an oil particle counter. Background technique [0002] With the application and development of modern hydraulic technology, hydraulic transmission has been widely used in aviation, machinery manufacturing, petrochemical and other technical fields, and the workload of failures and maintenance is also increasing. The problem of component life is more prominent and important. With the extensive use of components such as pumps, valves and various filters in mechanical equipment systems, factors that can cause mechanical failures also increase, which may cause mechanical parts to wear, corrode, block small flow channels, and even cause some Critical components fail. At present, the concept of oil pollution degree is introduced in the detection and analysis methods of oil pollution status to evaluate the contamination of oil. Oil pollution degree refers to the content of solid particle pollutan...

Problems solved by technology

But one of the shortcomings of this type of oil particle counter is: the use of shading method for oil solid particle counting is when the solid particles in the oil pass through the sensor beam, by measuring the intensity and frequency of light blocked by the particles when they pass through the sensor to get the size and number of particles

However, the actual situation is that the solid particles in the oil are usually small particles less than 10 μm, and the solid particles may overlap and pass through the sensor beam during counting, because: the infusion tube and sample pool of the traditional technology oil particle counter are difficult to add to the size of about 10 μm width

Moreover, there must be solid particles above 10 μm or even 100 μm in the liquid sample, and if the infusion tube and sample pool are too small, it will cause blockage
