The invention discloses a urea solution supply device which comprises a urea pump assembly, a sensor assembly and a urea tank, the urea pump assembly comprises a shell, a urea pump and a controller are arranged in the shell, the sensor assembly is fixed to the outer wall of the shell and extends into the urea tank, and the sensor assembly comprises a liquid inlet pipe, a heating water pipe and a urea sensor. The liquid inlet pipe and the heating water pipe are in fluid communication with the urea pump, and the controller is electrically connected with the urea pump and the urea sensor. According to the urea solution supply device, the urea pump, the sensor, the pipeline and other parts are integrated, redundant pipelines are omitted, leakage is reduced, the liquid level, temperature, quality, pressure and the like of the urea solution are intelligently monitored, it is guaranteed that the urea solution is reliably and stably conveyed, the overall structure is compact, the whole vehicle installation space is greatly saved, and cost is reduced.
Description
technical field [0001] The invention relates to the technical field of aftertreatment of diesel engine exhaust, in particular to a urea solution supply device. Background technique [0002] As diesel engine emission regulations become increasingly stringent, the requirements for high integration, miniaturization, and convenient installation and maintenance of various components of the diesel engine SCR system are also increasing. Among them, the urea supply system is the core component of the SCR system, and the miniaturization and integration have been paid more and more attention. [0003] At present, the urea supply system in the traditional SCR system is mainly an independent urea pump connected to the urea sensor installed on the urea tank through pipelines. The components of this type of system are scattered and the connecting pipelines are complicated, which requires a certain amount of attention in the installation and layout of the vehicle. Space and location to ar...
