Embodiment Construction

[0018] see figure 1 and figure 2 , figure 1 Only one urea metering pump is drawn in the figure, and actually one computer can control and calibrate multiple urea metering pumps; the following takes one urea metering pump as an example to illustrate the automatic calibration system of the urea metering injection pump of the present invention.

[0019] The urea metering injection pump automatic calibration system includes a water tank 10, the water tank 10 is connected with at least one urea metering pump 8 through a pipeline, the urea metering pump 8 is fixed by a clamping cylinder 7, and the urea metering pump 8 is communicated with the water cup 4 through a pipeline, The water tank 10 communicates with the water cup 4 through the pipeline and the drain pump 6. The drain pump 6 is used to draw water to the water cup 4 through the pipeline. The pipeline between the drain pump 6 and the water cup 4 is also connected with a suction pipe cylinder 5 for replenishing the water cup...

Abstract

The invention discloses a urea measuring jet pump automatic calibration system. The urea measuring jet pump automatic calibration system comprises a water tank, and the water tank is connected with at least one urea measuring pump through pipes; the urea measuring pump is fixed through a clamping air cylinder, the urea measuring pump 8 is communicated with a cup through a pipe, the water tank is connected with the cup through a pipe and a draining pump, the draining pump is used for pumping water from the pump through the pipe, and the pipe between the draining pump and the cup is provided with a sucker air cylinder for supplementing water from the cup; the water cup is arranged on an electronic balance, which is connected with the input end of a computer through a CAN (controller area network) bus and a network server, the output end of the computer is connected with the urea measuring pump through the CAN bus and the network server, and a barcode scanner / scanning spear is connected between the network server and the urea measuring pump. The urea measuring jet pump automatic calibration system can automatically calibrate the urea measuring pump, reduce environmental pollution by substituting water for urea solution, perform calibration on multiple urea measuring pumps simultaneously and ensure quality tracing of products to the maximum extent.

Description

technical field [0001] The invention relates to a calibration system of a diesel vehicle exhaust post-treatment purification system, in particular to an automatic calibration system and a calibration method for a urea metering injection pump. Background technique [0002] In the prior art, the calibration of urea in the post-treatment and purification process of diesel vehicle exhaust adopts a purely manual calibration method, that is, the clamping of the metering pump, the start-up control of the metering pump, the issuance of injection quantity commands, weighing, reading, recording, and metering The data curing of the pump is done manually, which consumes a lot of time, is inefficient, and has large artificial measurement errors. At the same time, data management is also difficult. At the same time, urea is used for calibration, which causes large pollution and high cost. In addition, no network server is used. When multi-station calibration is performed at the same time...
