履带式工程机械是一种在建筑基础工程中成孔作业的施工工程设备。广泛用于市政建设、公路桥梁、高层建筑等地基础施工。履带式工程机械行走是靠履带，只适合在工地内移动行走，无法进入加油站进行加柴油，一般是将柴油运输到旋挖钻边上加注，此时便需要一种加油设备将燃油从油桶加注到旋挖钻的油箱，因此配套一台采用旋挖钻直流电源作为动力源的加油设备是非常必要的，要求加油设备稳定，耐高温，加注流量大。
Crawler engineering machinery is a kind of construction engineering equipment which is used to make holes in the construction foundation project. Widely used in municipal construction, highway and bridge, high-rise buildings and other foundation construction. Crawler construction machinery walking is relying on tracks, only suitable for mobile walking in the site, can not enter the gas station to add diesel fuel, generally diesel fuel transported to the side of the rotary drilling refueling, at this time it will need a refueling equipment from the fuel drum fuel to the rotary drilling tank, so supporting a rotary drilling drilling DC power supply as a power source of the refueling equipment is very necessary, the requirements of the refueling equipment is stable, high-temperature resistance, refueling The refueling equipment is required to be stable, high temperature resistant and have a large flow rate.

国内目前主流工程机械厂家针对履带式工程设备的燃油加注，均配套一台直流加油泵，采用设备自带的电瓶作为电源，加油泵的电机均使用直流有刷电机，这类电机不可连续工作，单次工作30分钟后需停止，已经无法满足履带式工程机械设备需求，加上作业环境恶劣，雨天/高温工作，很多加油泵出现电机烧了的现象，主要原因是电机长时间运行，过载，温度过高，抗震差，不防水等引起。
Domestic mainstream construction machinery manufacturers for tracked engineering equipment fuel filling, are supporting a DC refueling pump, using the equipment's own battery as a power source, the refueling pump motor are used DC brush motor, this type of motor can not be continuous work, a single working 30 minutes after the need to stop, has not been able to meet the needs of tracked engineering machinery and equipment, coupled with the operating environment is harsh, rainy days/high temperature work, a lot of refueling pumps appeared to the phenomenon of the motor burnt, the main reason for this is that the motor is running for a long time, overloading, over-temperature, poor seismic, not waterproof, etc. caused.

履带式工程机械在工地讲究的是开工率，如何保证加油泵的稳定性是非常重要的，海同工业流体研发团队通过现场实地考察，针对性研发了这款无刷直流加油泵，很好的解决了客户的需求。采用无刷电机配套机油泵具有如下特点
