Description
Technical field
The utility model relates to diesel engine protection against cold and freezing conditions technical field, is specifically related to a kind of diesel engine oil circuit protection against cold and freezing conditions device.
Background technique
At present, general is automobile or other equipment of power with the diesel engine, actuating ratio is difficult at low temperatures, at high and cold low temp area, must be fuel ability normal starting and operation all with the lower diesel oil of condensation point, because the price of the low diesel oil of doubtful point is higher, and mostly is and does not reach normal label, is that powered device has been subjected to certain restriction in the use of high and cold low temp area so make with the diesel engine.One of major reason that causes above-mentioned situation is exactly that fuel tank, the oil circuit of automobile or other equipment do not have the performance of protection against cold and freezing conditions, thereby causes work normally to run.It is particularly outstanding that this type of situation seems in the automobile carrier.
Summary of the invention
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of simple in structure, with low cost, easy for installation, diesel engine oil circuit protection against cold and freezing conditions device that protection against cold and freezing conditions is effective is provided.
Its technological scheme is: comprise oil box, petroleum pipeline and preheater.The periphery of described oil box is enclosed with interlayer, and the upper and lower end of this interlayer is provided with intake pipe and outlet pipe, and intake pipe and outlet pipe are connected in series in the engine cycles water lines; Be enclosed with interlayer around the outer wall of described petroleum pipeline, the end of this interlayer is provided with water intake and water outlet, and water intake and water outlet are connected in series in the engine cycles water lines; Described preheater is the closed enclosure body structure of circle or rectangle, and inside is cavity, is provided with electric heating tube in the cavity, preheater casing top is provided with pore, top one side is provided with oil inlet pipe, and the bottom of preheater is provided with oil outlet tube, and this oil outlet tube is connected with the oil inlet pipe of high pressure oil pump.
Wherein, the electric heating tube in the described preheater is connected its supply voltage with power supply by preheating switch
Be direct current 12V-24V or external alternating current 220V.
The utility model has simple in structure, easy to use, with low cost and can make automobile or other equipment normally start the advantage of operation at high and cold low temp area compared with prior art.
Description of drawings
Fig. 1 is a kind of embodiment's of the utility model a structural representation;
Fig. 2 is the generalized section of petroleum pipeline among Fig. 1.
Embodiment
Shown in Fig. 1-2, a kind of diesel engine oil circuit protection against cold and freezing conditions device comprises oil box 1, petroleum pipeline 2 and preheater 3.The periphery of described oil box 1 is enclosed with interlayer 11, and the upper and lower end of this interlayer is provided with intake pipe 12 and outlet pipe 13, and intake pipe 12 and outlet pipe 13 are connected in series in the engine cycles water lines; Be enclosed with interlayer 21 around the outer wall of described petroleum pipeline 2, the end of this interlayer is provided with water intake 22 and water outlet 23, and water intake 22 and water outlet 23 are connected in series in the engine cycles water lines; Described preheater 3 is the closed enclosure body structure of circle or rectangle, and inside is cavity, is provided with electric heating tube 31 in the cavity, preheater 3 casing tops are provided with pore 34, top one side is provided with oil inlet pipe 32, and the bottom of preheater 3 is provided with oil outlet tube 33, and this oil outlet tube is connected with the oil inlet pipe of high pressure oil pump.Electric heating tube 33 in the described preheater 3 is connected with power supply V by preheating switch K, and its power supply V voltage is direct current 12V-24V or external alternating current 220V.
When installing and using the utility model, the oil outlet tube 33 of preheater 3 is connected on the oil inlet pipe of high pressure oil pump, with intake pipe 12 and the outlet pipe 13 on the oil box 1 peripheral parcel interlayer 11, and the water intake 22 and the water outlet 23 that wrap up on the interlayer 21 around petroleum pipeline 2 outer walls are connected in series on the circulating water pipeline of former motor, it is connected near the motor end as far as possible, so that heat enters water tank again through behind this device earlier.Before the starter-generator, at first open preheating switch K, utilize electric heating tube 33 in the preheater 3 with the fuel Heating in preheater 3 cavitys, startup will be more or less freely, behind the engine start, wrap up interlayer 21 around hot water process oil box 1 peripheral parcel interlayer 11 in the body and petroleum pipeline 2 outer walls, make the fuel oils that reach in the petroleum pipeline 2 in the oil box 1 obtain heat, thereby prevent to finish the generation of cured phenomenon, reach at high and cold low temp area and make automobile or other equipment normally start the purpose of operation.
