Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] see Figure 1-5 As shown, a liquid particle detector includes a housing 100, the housing is provided with a peristaltic pump 119, a laser light source 120 and a photoelectric receiver, the laser light source and the photoelectric receiver are relatively arranged, and the laser Between the light source and the photoelectric receiver there is a sample detection chamber 121 for the liquid to be detected to pass through. The flow direction of the fluid in the sample detection chamber is perpendicular to the parallel light rays emitted by the laser light source. One end of the sample detection chamber is formed with a liquid inlet 1210 , the other end is formed with a liquid outlet...

Abstract

The invention discloses a liquid particle detector which comprises a shell, wherein a peristaltic pump, a laser light source and a photoelectric receiver are arranged in the shell; the laser light source and the photoelectric receiver are arranged opposite to each other; a sample detection cavity for a to-be-detected liquid to pass through is formed between the laser light source and the photoelectric receiver; the flow direction of the fluid in the sample detection cavity is vertical to the parallel beam emitted by the laser light source; a liquid inlet is formed in one end of the sample detection cavity and a liquid outlet is formed in the other end; the laser light source and the photoelectric receiver are separately connected to a controller through a laser driving circuit and a signalprocessing cavity; and the controller is connected to the peristaltic pump which pumps the to-be-detected liquid into the sample detection cavity through a peristaltic pump driving circuit. The liquid particle detector disclosed by the invention can detect the quantity of bubbles in the liquid accurately.

Description

technical field [0001] The invention relates to the technical field of liquid particle detectors, in particular to a liquid particle detector. Background technique [0002] The pollutants of hydraulic oil mainly include solid particles, air, water and chemical substances, etc. Among them, solid particle pollutants are the most harmful pollutants in mechanical hydraulic systems, and they are the main cause of wear, sticking and failure of hydraulic components. According to relevant data, more than 70% of hydraulic system failures are caused by oil pollution. Practice has proved that the use of oil particle pollution detection technology and effective pollution control measures can significantly improve the working life and reliability of the equipment hydraulic system. [0003] At present, most foreign aviation and ship hydraulic systems use online detection methods to detect the particle content in hydraulic oil, and online detection methods have always been the research di...
