Abstract

The invention relates to an online monitoring system for engineering machinery hydraulic oil. The online monitoring system comprises a first sampling pipe, a first thermometer, a first valve, an electromagnetic pump, a buffering oil pool, a third thermometer, a first oil quality sensor, a pressure sensor and an oil returning device. The oil inlet end of the first sampling pipe is connected with an oil returning pipe of a shop truck, the oil outlet end of the first sampling pipe is connected with the oil inlet end of the electromagnetic pump, the first thermometer and the first valve are arranged on the first sampling pipe, the first valve is closer to the electromagnetic pump compared with the first thermometer, the oil outlet end of the electromagnetic pump is connected with the oil inlet end of the buffering oil pool, the first oil quality sensor and the third thermometer are arranged on the buffering oil pool, and the pressure sensor is arranged between the oil outlet end of the buffering oil pool and the oil inlet end of the oil returning device. The online monitoring system solves the problem that in a hydraulic system of an engineering machinery vehicle, sampling is difficulty, and the purpose that collected oil samples can timely reflect the running state of equipment and can also be used for judging the overall state of the system comprehensively are realized.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to an online monitoring system for hydraulic oil of construction machinery. Background technique [0002] According to statistics, nearly 2 / 3 of the failures of the hydraulic system come from the pollution of the hydraulic oil medium. The hydraulic system of construction machinery is in a sealed and high-pressure environment, and the condition of the hydraulic oil medium cannot be directly reflected. A series of oil monitoring sensors currently on the market are affected by the special working conditions of construction machinery. The construction machinery vehicles have small working space, large vehicle vibration during work, harsh working environment, compact hydraulic system pipeline layout, and relatively narrow machine space. , the system pressure can reach 30-50 MPa, the flow rate is large, and the hydraulic oil temperature can reach 80°C-90°C. Temperature, flow rate, a...
