Problems solved by technology

The calorific value of low-grade diesel oil is lower than that of high-grade diesel oil, and the amount used in the process of use is also higher than that of high-grade diesel oil. At the same time, the price is also higher than that of high-grade diesel oil, which results in much higher vehicle operating costs than high-grade diesel oil.

Abstract

The invention provides a double oil supply system and a mining dump truck. The double oil supply system comprises an engine, a radiator connected with the engine, a heating unit connected with the radiator, a first oil supply unit connected with the engine, a second oil supply unit connected with the engine and the heating unit, and a switching unit connected with the first oil supply unit and the second oil supply unit, wherein a temperature controller is arranged in the heating unit; and after the temperature controllers senses that fuel in the second oil supply unit reaches a preset temperature, the switching unit controls the first oil supply unit to close and controls the second oil supply unit to open. According to the technical scheme, high-grade diesel is used in most of operation time, low-grade diesel is just used during initial operation each time and before shutdown, and thus the oil cost of users is reduced.

Description

technical field [0001] The invention relates to the field of fuel supply, in particular to a double fuel supply system and a mining dump truck. Background technique [0002] In recent years, mining dump trucks have developed rapidly, and the market share has increased sharply. Most of the engines required for mining trucks are high-power engines, and the attendance rate is very high, which consumes a lot of fuel. Due to the cold winter in the north, the existing mining dump trucks must use low-grade diesel. The calorific value of low-grade diesel oil is lower than that of high-grade diesel oil, and the amount used in the process of use is also higher than that of high-grade diesel oil. At the same time, the price is also higher than that of high-grade diesel oil, which makes the operating cost of vehicles much higher than that of high-grade diesel oil. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in...
