Description

The automatic heating temperature control device of diesel-oil vehicle oil circuit

Technical field

The utility model relates to a kind of automatic heating temperature control device of diesel-oil vehicle oil circuit.

Background technique

The solidifying point of conventional diesel oil is higher relatively, and the locomotive that causes using diesel engine oil circuit wax deposition phenomenon of blocking usually can occur in the winter time the time, thereby has influence on the proper functioning of diesel engine.In order not influence normal transportation manufacturing operation, diesel locomotive has to use instead low-freezing diesel oil in the winter time the time alleviating oil circuit wax deposition blocking problem, but the price of low-freezing diesel oil is relatively costly, and this just causes the transportation production cost to improve.In order not raise the cost, also there are a lot of drivers not select to change low-freezing diesel oil at present, and cold when taking place to stop up at the locomotive oil circuit because of meeting, take the way of naked light baking fuel tank and oil circuit to thaw, this measure is very danger, very easily causes fire or explosive accident.Relevant declaration of an accident is of common occurrence.So far, the Electric heating appliance of diesel-oil vehicle oil circuit has appearred in existing technology, but the working principle of these Electric heating appliances all is that the insulated heating wire is immersed in the diesel oil in the oil circuit; Heat to diesel oil; The defective of this mode is that insulated heating wire's isolation layer is easy to be corroded and take place deterioration phenomenon, causes electric heating wire to be short-circuited; Produce localized hyperthermia and scald broken oil pipe, initiation fire.

The model utility content

The technical problem that the utility model will solve is: be prone to cause locomotive oil circuit wax deposition blocking problem in the winter time because of solidifying point is higher relatively in order to solve present conventional diesel oil; And existing oil circuit Electric heating appliance existence provides a kind of automatic heating temperature control device of safe and reliable diesel-oil vehicle oil circuit than the problem of big potential safety hazard.

The utility model solves the technological scheme that its technical problem adopted: a kind of automatic heating temperature control device of diesel-oil vehicle oil circuit; Include Vehicular accumulator cell, oil circuit pipe, diesel-oil filter, resistance wire and temperature detect switch (TDS); In the tube wall of oil circuit pipe, be entrained with the carbon fiber exothermic wire layer; Said Vehicular accumulator cell, resistance wire, temperature detect switch (TDS) and the series connection of carbon fiber exothermic wire layer form the loop, and wherein resistance wire and temperature detect switch (TDS) all are arranged in the diesel-oil filter.Take all factors into consideration the coagulating property and the combustion efficiency characteristic of diesel oil, the control range of temperature detect switch (TDS) is set in 50 ℃～60 ℃.When the temperature of diesel oil in the oil circuit was lower than 50 ℃, temperature detect switch (TDS) was closed on-state, heater circuit work, the carbon fiber exothermic wire layer heating heating diesel oil in the oil circuit pipe; When oily temperature rises to 60 ℃, the temperature detect switch (TDS) automatic disconnection, heating process stops, and waits for that the oil temperature falls after rise naturally; Temperature detect switch (TDS) is connected again automatically when the oil temperature falls after rise to 50 ℃, heater circuit work, the heating of carbon fiber exothermic wire layer.Therefore,, the diesel fuel temperature in the oil circuit is remained between 50 ℃～60 ℃, not only can not solidify the wax deposition phenomenon, also keep the good operation temperature through this automatic heating temperature control device.Simultaneously,, directly do not contact, do not have etching problem with diesel oil because the selection of the heat generating material of heater circuit is that carbon fiber exothermic wire and carbon fiber exothermic wire are arranged in the tube wall of oil circuit pipe; Whole oil line pipe is pipe heating entirely almost, to the homogeneous heating of diesel oil.

Loop for the carbon fiber exothermic wire layer in Vehicular accumulator cell and the oil circuit pipe is connected; Outlet for fear of the carbon fiber exothermic wire layer is impaired because of the external force effect; And the Outlet of carbon fiber exothermic wire layer is connected with nearby locomotive body's position lead, this vehicle body position is connected with Vehicular accumulator cell through lead again.

The beneficial effect of the utility model is: the automatic heating temperature control device of this diesel-oil vehicle oil circuit can make the diesel fuel temperature in the diesel locomotive oil circuit remain in the only scope; Both avoided diesel oil to solidify wax deposition and stopped up oil circuit, and made diesel oil keep the good operation temperature again.The application of this device makes diesel locomotive needn't use comparatively expensive low-freezing diesel oil in the winter time again instead, has practiced thrift resource and cost of transportation.Simultaneously, because the heating medium of this device does not directly contact with fuel oil, do not have etching problem, thereby its Security, reliability are higher than existing product, prolong working life greatly.
