Oil collector

Abstract

This is oil collector used of the testing platform of injection pump. On this oil collector is installed oil injection sensor. This sensor is not only to ensure every oil cylinder is whether not inject oil but also can to survey every oil cylinder injective moment (or phase angle), then to calculate dynamic injective phase angle. As only to differentiate in the collector is whether not injection, so the sensor's linear degree can be lower, and its construction is simple. The output signals of this sensor are switched signals using to show the injection or not injection, so its resist disturbed ability is strong.

Description

technical field [0001] The invention relates to an oil collector which can judge whether there is oil sprayed in according to the oil pressure fluctuation range in the container. Background technique [0002] The oil pressure in the oil collector is measured using a specially designed pressure sensor. At present, the common pressure sensors on the market have various forms such as piezoelectric sensors and piezoresistive sensors. Due to the consideration of measurement accuracy, the structure is relatively complicated, and corresponding amplification or conditioning circuits must be configured and passed through A / D. After the conversion, it can be transmitted to the microcomputer for processing. If these sensors are directly used as the test signal source on the fuel injection pump test bench, it will not only have a complex structure, a large volume, but also a high cost, which is not conducive to popularization and application. Contents of the invention [0003] In vie...
