Intelligent DC petrol pump

Abstract

The invention provides an intelligent DC petrol pump comprising a petrol pump main body, a DC power source for supplying power to the petrol pump main body, and an intelligent control system, wherein the intelligent control system comprises an information sampling module, an A / D conversion module, an intelligent calculation module and a working condition display module; the information sampling module comprises a temperature sampling module and a current sampling module; temperature and current information sampled by the information sampling module is converted by the A / D conversion module, and then input to the intelligent calculation module; and the obtained data are processed by the intelligent calculation module, and then input to the working condition display module. With the intelligent control system, the intelligent DC petrol pump can be monitored in such a manner that when the working temperature of the intelligent DC petrol pump is over-high, the intelligent DC petrol pump is blocked or clamped during work, or an oil storage tank is empty, a technician can carry out corresponding protective measures in advance, so as to reduce the overburning rate of the petrol pump; and due to the level control of the oil tank of a construction machine, oil filling operation can be stopped automatically when the oil tank is fully filled with oil, and the oil filling quantity can be displaced and controlled.

Description

Technical field [0001] The invention relates to the technical field of fueling equipment for engineering machinery, in particular to an intelligent DC fueling pump. Background technique [0002] At present, the DC fuel pump on the market is a diesel and kerosene vane pump. Due to the harsh operating environment of this type of fuel pump, poor oil cleanliness, and incorrect use by users, the service life of the fuel pump is generally not High, as long as a few months, as few as a few days, there will be phenomena such as motor burnout and impurity stuck. Once there is a problem with the fuel pump, the shutdown will affect the normal operation of the diesel engine. Summary of the invention [0003] The technical problem to be solved by the present invention is to overcome the technical problems in the prior art that fuel pumps are prone to motor burnout and impurity jamming, and provide an intelligent DC fuel pump to realize real-time monitoring of the fuel pump, and has an alarm f...

AI Technical Summary

Problems solved by technology

[0002] The DC fuel pump currently on the market is a diesel or kerosene vane pump. Due to the harsh operating environment of this type of fuel pump, poor oil cleanliness, and incorrect use by users, the service life of the fuel pump is generally short. High, as many as several months, as little as a few days, there will be phenomena such as motor burnout, impurities stuck, etc.

Once there is a problem with the fuel pump, the shutdown will affect the normal operation of the diesel engine
