Abstract
The present invention relates to an electric heating diesel oil filter. An electric heater is arranged between a manual pump body and a filter core casing. An insulating cover pate, a pressure spring, a positive electrode board, a heating plate and a negative electrode board are orderly overlapped together and installed inside the insulating base box of the electric heater. The positive electrode board is connected with an anode terminal through an automatic temperature-control switch installed at the manual pump body. The negative electrode board is connected with a cathode terminal. The electric heater heats influent diesel oil automatically according to a set minimum temperature, which improves the oil filtering efficiency of the diesel oil filter. When the environmental temperature is higher than a set maximum temperature, heating is stopped automatically. A water level warner is arranged inside an oil-water separator which is in sealed connection with the lower end of the filter core casing. The inside of the water level warner is provided with a high water level electrode and a low water level electrode which are connected with a control chip circuit. When the water level rises and submerges the high water level electrode and the low water level electrode synchronously, a control chip is triggered to be communicated with a warning circuit. The water level warner is not provided with moving parts and has good reliability and high flexibility.
Description
Technical field
The present invention 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 problem to be solved in the present invention provides a kind of electric heating diesel fuel filter.
For solving the problems of the technologies described above, technological scheme of the present invention 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 invention has the beneficial effects as follows: 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 present invention 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 invention does not have moving parts, and good reliability is highly sensitive.

Embodiment
The present invention is further described below in conjunction with drawings and Examples.
The ambient temperature of the automatic energising of temperature automatically controlled switch 8 is set at-3 ℃, and the ambient temperature of outage is set at 6 ℃ automatically; Minimum and the highest setting temperature is adjustable.When the ambient temperature of low temp area was lower than-3 ℃, diesel oil through the filler opening 9 of electric heater 4, after heater band 13 intensifications by automatic energising heating, flowed into filter cores through oil outlet 18 through inlet connector 3 inputs, 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 was higher than 6 ℃, temperature automatically controlled switch is outage automatically, and electric heater 4 stops heating automatically.
Water level alarm of the present invention 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, do 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.
