Problems solved by technology

At present, the fuel injection pump test bench usually adopts the method of artificial visual test tube in the measurement method of fuel quantity. When using this method to measure, it needs to collect hundreds of times of fuel injection with glass test tubes, and the work efficiency is low; and the reading is done with the naked eye. Observe and read the scale of the oil level on the test tube, the measurement accuracy is low
In addition, the existing fuel injection pump test bench can only measure the static fuel supply phase angle of each cylinder

Abstract

This invention relates to a test stand for automatically measuring volume of an oil spray pump including a sprayer, a collector, a deforming stabilizer, a collect / discharge electromagnetic valve and a flow sensor, among which, the oil collector is mounted on the outlet of the oil sprayer connected with the deforming regulator via conduit, outlet of which is linked to the inlet of the collect / discharge valve, the flow sensor is mounted on the valve, the top overflow lip of the sensor and outlet of the valve are connected with the oil tank via return tubes which applies the sensor in the collector to determine it the pump is at the spraying state, either solves the problem of costing too long time to test small volume by single volume flow sensor or complicated structure of a multi-volume flow sensor.

Description

technical field [0001] The invention relates to a fuel injection pump fuel quantity automatic measurement test bench which can automatically measure the fuel injection quantity of each cylinder and the dynamic fuel injection phase angle of each cylinder. Background technique [0002] Fuel injection pump test bench is the equipment used for adjusting and checking the fuel injection pump of diesel engine. At present, the fuel injection pump test bench usually adopts the method of artificial visual test tube in the measurement method of fuel quantity. When using this method to measure, it needs to collect hundreds of times of fuel injection with glass test tubes, and the work efficiency is low; and the reading is done with the naked eye. Observe and read the scale of the oil level on the test tube, the measurement accuracy is low. In addition, the existing fuel injection pump test bench can only measure the static fuel supply phase angle of each cylinder. SUMMARY OF THE INVE...
