Embodiment 1
Connect with temperature controller after two panels heating plate parallel connection, load in shell and adopt screw and spring shim to be pressed on the support column of shell between PTC heating plate and two electrode slices, form heater assembly, two lead-in wires of heater assembly are drawn from Wiring port by two electrode columns, wherein through a piece of connection sheet positive terminal as external power supply after electrode column series connection bi-metal temperature controller, another root electrode column stretches out as the negative terminal of external power supply。Two electrode columns are pounded in connector by interference fit, connect vehicle power with this, it is possible to dock with body harness very easily。
When diesel stream cleaner, diesel oil can be full of whole filter tank, first the metal temperature-sensitive face of temperature controller can sense the temperature of current diesel oil, if temperature is lower than the conducting temperature of temperature controller, temperature controller turns on, and heater moment starts, by heating plate, the diesel oil in fuel system is heated, when around, diesel fuel temperature reaches regulation requirement, by temperature controller control heater stop heating, furthermore the thermostatic characteristics of PTC itself also ensure that perfectly safe。Consequently, it is possible to solve the shortcoming that diesel low-temperature liquidity is poor safely, easily, alleviate the resistance of motion of parts, extend the service life of electromotor。Improve efficiency of combustion simultaneously, improve tail gas pollution。
Before fuel oil consumption, it is preheated the mobility optimizing fuel oil, the profit in fuel oil is made more to be easily generated separation, owing to diesel oil is different with the proportion of water, isolated moisture content is deposited on the bottom of filter tank, when water accumulation level reaches set upper limit, the level sensor probe installed bottom water tumbler can sense water level very timely, reminds driver's personnel's draining, and operator can carry out draining by the drain valve on cleaner tank。Level sensor is made up of electrode and control circuit plate, different with the electrical conductivity of oil according to water, and when two electrodes are immersed in oil or one end the other end is in oil in water simultaneously, circuit is obstructed, does not monitor。Only when two electrodes submerged in water simultaneously, circuit just can turn on, and level sensor output signal produces change。Output signal is fed back to automobile ECU or external circuits, ECU or external circuits and the output signal of level sensor is converted the signal that directly can appreciate that for people by level sensor, reminds driver personnel to discharge water in time。Driver personnel can pass through to loosen drain valve and be got rid of by the hydrops in cleaner tank。In order to avoid vehicle in the process of moving because of concussion or other unexpected factor generation monitoring by mistake, can designing addition monitoring delay circuit in control circuit, delay time is short, when not affecting water level information reflection, it is ensured that monitor the accurate, rapid of information。It is highly sensitive, good reliability。
Embodiment 2
Multiple heating plates are connected in parallel, then control to connect with temperature, load in shell, and adopt screw and spring shim to be pressed on the support column of shell between PTC heating plate and two electrode slices, form heater assembly。Other structures and annexation are identical with the technical scheme in the present embodiment 1, realize fuel Heating and the monitoring water level of cleaner pot bottom。
Concrete enforcement step: be first arranged on shell fixing hole by the mode that heater assembly screw fastens, two electrode columns of heater assembly are loaded by interference fit and in the connector of shell one, then connect vehicle-mounted working power。Two electrodes of heater assembly use epoxide-resin glue embedding again by after interference fit; two kinds of sealing means duplicate protections are have employed above; safer, what both ensure that heater firmly installs the sealing that in turn ensure that heating chamber, it is therefore prevented that leakage phenomenon in use occur。Then installing level sensor, shell put into by water level sensor circuit plate, is connected with the electrode pad of circuit board by sensor electrode with scolding tin, then uses epoxide-resin glue embedding。Finally upper cover is placed in welding groove, welds with friction welding apparatus, it is ensured that the sealing in cavity, do not have any leakage。Again side cover is buckled on shell heating barred body, forms circular oil pipe, for logical oil, it is ensured that flow to after the oil of cleaner tank is heated in flowline in supply engine oil circuit by oil inlet pipe。
