Abstract
The utility model relates to an electrical heating fuel oil filter. An electrical heater is arranged between a manual pump body and a filtering core shell; an insulating cover plate, a pressure spring, a positive electrode plate, a heating plate and a negative electrode plate are superimposed and arranged in an insulating stool box of the electrical heater in sequence; the positive electrode plate is connected with a positive terminal by an automatic temperature controlled switch arranged on the manual pump body; the negative electrode plate is connected with a negative terminal; the electrical heater heats the inflowing diesel automatically according to the set lowest temperature so as to improve the oil-filtering efficiency of the fuel oil filter; and when the ambient temperature is higher than the set highest temperature, heating is stopped automatically. A water level alarm is arranged in an oily water separator which is connected with the lower end of the filtering core shell in a sealing mode, and is internally provided with a high water-level electrode and a low water-level electrode which are connected with a control chip; when the water level rises and the high water-level electrode and the low water-level electrode are simultaneously immersed, the control chip is triggered so as to switch on an alarm circuit; and the water level alarm does not have moving parts and has good reliability and high sensitivity.
Description
Technical field
The utility model relates to a kind of diesel-oil filter, particularly a kind of electric heating diesel fuel filter.
Background technique
In low temperature season and area, diesel oil viscosity is big, and mobile poor, the oil strain efficient of traditional diesel-oil filter is low, influences the proper functioning of diesel engine.The less reliable of the water level alarms such as buoy in the oil and water seperator of conventional diesel filter cleaner.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of electric heating diesel fuel filter.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of electric heating diesel fuel filter comprises the manual pump housing, filter core housing that is connected as a single entity with inlet connector and flowline connection to subsea and the oil and water seperator that is tightly connected with filter core housing lower end; The upper end of electric heater is tightly connected with the lower end of the manual pump housing, and the upper end of the lower end of electric heater and filter core housing is tightly connected.Be provided with electric heater insulation cover plate, stage clip, positive electrode plate, the negative electrode plate of filler opening and be placed in heater band in the groove of negative electrode plate and superpose successively and be installed in the electric heater insulation base box that is provided with oil outlet, insulation cover plate and insulation base box are sealed and matched.Positive electrode plate is connected with positive terminal by the temperature automatically controlled switch that is installed on the manual pump housing, and negative electrode plate is connected with negative terminal, and positive terminal and negative terminal are connected with safety power supply by lead.
In the oil and water seperator that is tightly connected with filter core housing lower end, be provided with water level alarm, be provided with the high water level electrode and the low water level electrode that are connected with the control chip circuit in water level alarm, the lower end of water level alarm is connected with safety power supply that is positioned at the water level alarm outside and acoustooptic alarm element by electrical plug.
The beneficial effects of the utility model are: in low temperature season and area, temperature automatically controlled switch can be according to the minimum temperature of setting, automatically the heater band of connecting by the safety power supply power supply heats the diesel oil that flows into diesel-oil filter, reduce the viscosity of diesel oil, strengthen its flowability, improve the oil strain efficient of diesel-oil filter, guarantee the proper functioning of diesel engine; When ambient temperature reached the maximum temperature of setting, temperature automatically controlled switch is outage automatically.The utility model utilizes the different specific conductances of diesel oil and water, and when high water level electrode with low water level electrode all is immersed in the diesel oil or high water level electrode is immersed in the diesel oil and low water level electrode when under water, circuit is obstructed, do not report to the police; Have only when the water level rising, when while submergence high water level electrode and low water level electrode, trigger control chip and connect warning circuit.Water level alarm of the present utility model does not have moving parts, and good reliability is highly sensitive.

Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With the ambient temperature of the automatic energising of temperature automatically controlled switch 8 be set at-3 ℃ automatically the ambient temperatures of outage to be set at 6 ℃ of minimum and the highest setting temperatures be adjustable.When the ambient temperature of low temp area is lower than-3 ℃, diesel oil is through inlet connector 3 inputs, through the filler opening 9 of electric heater 4, after the heater band 13 by automatic energising heating heats up, flows into filter cores through oil outlet 18, again through hollow screwed pipe 5 and flowline connection to subsea 2 outputs.Heat temperature raising can reduce diesel oil viscosity at low temperatures, strengthens its flowability, improves the oil strain efficient of diesel-oil filter, guarantees that diesel engine oil circuit under low temperature environment is unimpeded, works well.When ambient temperature is higher than 6 ℃, temperature automatically controlled switch is outage automatically, and electric heater 4 stops heating automatically.
Water level alarm of the present utility model utilizes the different specific conductances of diesel oil and water, and when high electrode with low electrode all is immersed in the diesel oil or high electrode is immersed in the diesel oil and low electrode when under water, circuit is obstructed does not report to the police; Have only when the water level rising, when while submergence high electrode and low electrode, trigger control chip and connect warning circuit; It does not have moving parts, and good reliability is highly sensitive.
