Dirty oil and sewage discharge device for diesel engine bench experiment

Abstract

The invention discloses a dirty oil and sewage discharge device for a diesel engine bench experiment. The device comprises a dirty oil and sewage collection tank, a main conveying pipe, a conveying pump, an external pipe system and an electric control box, wherein the external pipe system comprises a plurality of collection pipes, an upstream part of the external pipe system is connected with a discharge hole of each test bench, a downstream part of the external pipe system is connected with the main conveying pipe, a downstream part of the main conveying pipe is connected to the dirty oil andsewage collection tank, the dirty oil and sewage collection tank is internally provided with a high liquid level sensor and a low liquid level sensor, a downstream part of the dirty oil and sewage collection tank is connected with a dirty oil treatment center through the conveying pump, the electric control box is connected with the conveying pump, the high liquid level sensor and the low liquidlevel sensor, and according to detection signals of the high liquid level sensor and the low liquid level sensor, start or stop of the conveying pump is controlled. The device is high in automation degree, saves materials, reduces the risk of contamination, avoids fire hazards, and has the advantages of reasonable structure, low cost, complete functions and simple operation.

Description

technical field [0001] The invention relates to a manufacturing process of a low-speed diesel engine, in particular to a dirty oil and sewage discharge device for a diesel engine bench test, and belongs to the technical field of diesel engine manufacturing. Background technique [0002] When the low-speed diesel engine is running, it will produce some dirty oil and sewage. From the operating principle of the diesel engine, these dirty oil and sewage are inevitable products and cannot be avoided. Put sewage, etc. Oily sewage contains some substances that are harmful to the environment and cannot be discharged directly. Moreover, with the increasingly stringent environmental protection requirements, the control of oily sewage discharge is becoming increasingly strict. [0003] see figure 1 , when the diesel engine is moving (bench test) before leaving the factory, the dirty oil and sewage generated by it is connected to the special sewage and sewage oil discharge system thro...
