Detailed Description
The following further describes embodiments of the present invention in order to facilitate further understanding of the present invention by those skilled in the art, and does not constitute a limitation to the right thereof.
Embodiment 1, referring to fig. 1, a protection device for an electric oil pump motor of a mobile gas station, the mobile gas station includes an oil storage tank 1 and an oiling machine 10 mounted on a mobile vehicle, the oil storage tank 1 and the oiling machine 10 are connected by an oil pipeline, an explosion-proof oil pump 2 is mounted on the oil pipeline, and the explosion-proof oil pump 2 is electrically connected to an explosion-proof control box 5; the oiling machine 10 is provided with an oil-gas separator, a measurement converter, a counter, a motor and an oil viewer; the oil-gas separator is used for separating gas in oil products and discharging the gas out of the oil products, and impurities in the oil products are filtered out to ensure that the oiling machine 10 and the output oil products do not contain gas impurities. The measuring transducer measures the volume of the output oil product. The counter is a display of the volume of fuel dispensed by fuel dispenser 10. The counter can display the oil filling amount (liter) once, the unit price (yuan/liter) of the oil on the day, the sum of money and the oil filling amount accumulation according to the functions of the oiling machine 10. The oil viewer is used for observing whether the oil contains gas or not.
