Abstract
An oil way pressurizer and heater of diesel vehicle comprises the following components: an oil way between an oil tank and an oil transfer pump, an oil feeding pipe and an oil return pipe which are provided in the oil tank. An electric heater is equipped to the oil way between the oil tank and the oil transfer pump. The middle part of the oil feeding pipe is connected with an auxiliary oil pump through a tee joint. A lower oil feeding pipe of the tee joint is equipped with a check valve. The lower end of the oil feeding pipe, the lower end of the oil return pipe and the auxiliary oil pump are equipped in an oil collection cup with an open mouth. The oil return pipe and the upper part of the oil feeding pipe are respectively provided with an electric heater. A temperature control switch is equipped to a filtering cup of the oil way. The whole oil way between the oil tank and the oil transfer pump is heated. When the vehicle operates in a low-temperature environment, the oil way does not freeze and the auxiliary oil pump can increase the pressure of a low-pressure oil way. The problems of air leakage in oil way, oil feeding stoppage and insufficient oil feeding are settled. The power performance of vehicle acceleration is improved. The oil collection cup increases the temperature around the oil feeding pipe in the oil tank and melts the waxiness. Heating the oil return pipe can quickly melt the waxiness in the diesel oil. The temperature increase effect is good and the fuel cost is reduced.
Description
Technical field
The utility model relates to a kind of diesel-powered vehicle oil circuit technology, particularly a kind of diesel-powered vehicle oil circuit pressurized, heated device.
Background technology
The product that a kind of diesel-powered vehicle oil circuit temperature booster is arranged in the prior art, this be with the power supply heating fuel tank on the car to whole section oil circuit between the fuel transfer pump, car moves at low temperatures, oil circuit can not condense, and removes that the cold snap oil circuit condenses from and the worry that causes the road upthrow to retouch.Its weak point is: if in use pipeline leaks gas, oil will can not occurring, oil circuit is not smooth, band carries the phenomenon of acceleration transport power deficiency.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, and it is good to have proposed under a kind of cryogenic conditions result of use, reduces the diesel-powered vehicle oil circuit pressurized, heated device of fuel cost.Solve oil circuit gas leakage and do not come the problem oily, that fuel feeding is not enough.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of diesel-powered vehicle oil circuit pressurized, heated device, oil circuit between comprising from the fuel tank to the fuel transfer pump and the rail that is located in the fuel tank, oil return pipe, to the oil circuit between the fuel transfer pump, electric heater unit is housed at fuel tank, be characterized in: the middle part of rail is connected with auxiliary oil pump by threeway, on the rail of the bottom of threeway, check valve is housed, the lower end of rail, the lower end of oil return pipe and auxiliary oil pump are arranged in the uncovered catchment cup, on oil return pipe and on the top of rail electric heater unit are housed all.
The technical problems to be solved in the utility model can also come to realize that further the wall of catchment cup has some oil permeable holes by the following technical programs.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, and the oil circuit middle part between from the fuel tank to the fuel transfer pump is provided with filter bowl, and the place adds coolant-temperature switch at filter bowl.
The utility model compared with prior art, heating fuel tank is to whole section oil circuit between the fuel transfer pump, car moves at low temperatures, oil circuit can not condense, in fuel tank, install auxiliary oil pump additional and can increase low pressure oil circuit pressure, solve oil circuit gas leakage and do not come the problem oily, that fuel feeding is not enough, improve vehicle and quicken tractive performance.Catchment cup is to improve the temperature around the rail in the fuel tank, dissolves wax.The oil return pipe heating can be dissolved the wax in the diesel oil rapidly, and temperature raising is effective, reduces fuel cost.Can make vehicle more than subzero 30 degree, use No. 0 diesel oil, when subzero 30 degree are following, use-No. 10 diesel oil.The filter bowl place adds coolant-temperature switch, and heating arrangement is realized automatic guidance, prevents the too high oil pipe that scorches of temperature, protective circuit safety.
Description of drawings
Fig. 1 is a structure diagram of the present utility model.
The specific embodiment
A kind of diesel-powered vehicle oil circuit pressurized, heated device, adopt power supply heating on the car, oil circuit 3 between comprising from the fuel tank to the fuel transfer pump and the rail 6, the oil return pipe 2 that are located in the fuel tank 10, to the oil circuit between the fuel transfer pump, electric heater unit is housed at fuel tank, the middle part of rail is connected with auxiliary oil pump 9 by threeway 7, on the rail of the bottom of threeway 7, check valve 8 is housed, the lower end of the lower end of rail 6, oil return pipe 2 and auxiliary oil pump are arranged in the uncovered catchment cup 1, on oil return pipe 2 and on the top of rail 6 electric heater unit are housed all.Electric heater unit can be arranged on oil pipe inside, also can be to use resistor wire to be coiled in outside the oil pipe.The wall of catchment cup 1 has some oil permeable holes.Oil circuit middle part between from the fuel tank to the fuel transfer pump is provided with filter bowl 5, and 5 places add coolant-temperature switch 4 at filter bowl, cuts off the power supply automatically when the control temperature reaches 50 °, works automatically in the time of 10 °.
