Description

The multifunctional diesel oil purifier

The utility model relates to a kind of multifunctional diesel oil purifier, especially a kind of automatic emptying oil circuit detection alarm, and filter housing can repeat the multifunctional assembled diesel engine automatic emptier of spinning of usefulness again.

At present, the filter of use for diesel engine is mainly by being installed in forming entering thick, the fine filtrator that diesel oil in the filter filters successively on the filter base, and thick, fine filtrator mainly is to be made of filter shell and installation paper filter within it.Though this filter can filter out the metal and the non-metal particle of most of large-size, but still contain tiny ferrous metal powder in the diesel oil after filtering, these metal powders can make the wearing and tearing between the kinematic pair of diesel engine and oil pump etc. accelerate, reduce its working life, and because of this filter can not be discharged the gas that enters in the filter, make the oil that enters in the diesel engine except that containing many tiny metallic dusts, also have a certain amount of gas, thereby influence the atomizing and the burning of diesel oil, reduce the power of motor, and make blowdown increase befouling environment.The fuel tank oil transportation generally all is to adopt rubber pipe or plastic tube to carry to filter, and as easy as rolling off a log leakage enters air, causes engine misses.In addition, because filter housing and paper filter element are the integrated type structure, be that integral body abandons in case paper filter element lost efficacy, because filter housing made by metal, thereby cause the significant wastage of metallic material.

For addressing these problems, I concentrate on studies at process, and have done a large amount of tests, have invented a kind of " the automatic emptying diesel energy-saving of spinning combined type purifying filter ", and applied for Chinese patent, the patent No. is 94243804.5, has solved the problem that blowdown, energy-conservation, automatic emptying filter housing repeat usefulness again preferably, but the cartridge filter of this structure and on threaded coupling need seal with seaming machine, operation is complicated, the manufacture cost height, the sealability instability is difficult to promote the use of; Because this filter cleaner does not have signalling device,, cause fault to can not get timely processing in addition, cause unnecessary economic loss so in installing and using process,, also can't predict in advance even break down.

The purpose of this utility model has been to overcome the deficiency of above-mentioned background technology, and a kind of multifunctional diesel oil purifier is provided, and it is simple in structure, and cost of production is low, and can detect the fault of fuel path in advance.

For achieving the above object, the technical solution that the utility model adopts is as follows:

A kind of multifunctional diesel oil purifier is made up of base, coarse-grain filtering device and fine filtrator.Base is provided with oil input channel, oil road, oil transportation road and air storing cavity, slightly, the fine filtrator structure is identical, form by filter housing and the filter core that is installed in the filter housing, filter housing and filter core are split-type structural, tube bottom is provided with magnetic patch in the filter core, magnetization oil collecting pipe in the filter core is connected on the base, the filler opening in the oil transportation road on the oil collecting pipe in the coarse-grain filtering device filter core and the base is connected, oil collecting pipe in the fine filtrator filter core is connected with the oil road on the base, slightly, the exocoel of fine filtrator is connected with oil input channel and oil transportation road on the base respectively, slightly, in the inner chamber of fine filtrator and exocoel have on base, the exocoel air outlet flue is connected with air storing cavity on the base, air storing cavity has air outlet flue to be connected with the external world, slightly, in the fine filtrator, on the exocoel air outlet flue automatic control pressure vent is installed, the automatic vent main valve is installed on the air storing cavity air outlet flue, its special way is that filter housing snaps onto in the attaching nut, and be sealedly connected on the inipple on the base by the attaching nut, coarse-grain filtering device seat upper end is connected with pressure transducer, pressure transducer is communicated with coarse-grain filtering device filter core exocoel, fine filtrator seat upper end is connected with pressure sensitive switch, pressure sensitive switch is communicated with fine filtrator filter core exocoel, the pressure transducer positive electrode is connected with the pressure gauge auxiliary electrode, the pressure gauge positive electrode connects positive source, the pressure sensitive switch positive electrode is connected with the buzzer auxiliary electrode, and buzzer positive electrode and beacon auxiliary electrode connect and compose fuel path electronic detection alarm.

The utility model so structure is simple especially, avoids filter housing to use seaming machine to seal because only need to adopt nut type to connect filter housing and base simultaneously, makes installation procedure and more simplifies, and cost of production greatly reduces; Owing to increased signalling device,, avoid unnecessary economic loss simultaneously so after installing and using, can find the fuel path fault in advance.
