Abstract
The utility model relates to a fuel filter device with a series connection structure, which comprises a base, a plunger type manual oil pump, a fuel coarse filter, a fuel fine filter, a fuel coarse filter heater, a fuel fine filter heater and an integrated water level alarm. The fuel filter device is characterized in that a fuel filter assembly which comprises the fuel coarse filter and the fuel fine filter is fixedly connected with the base; the plunger type manual oil pump is connected with the rear end of the fuel coarse filter; the fuel coarse filter heater and the fuel fine filter heater are assembled on the fuel coarse filter and the fuel fine filter respectively; and the integrated water level alarm is installed at the front end of the fuel coarse filter. The fuel filter device is optimally integrated through the modular connection base; while removing water effectively and cleaning particulate matter, the fuel filter device realizes the functions integrating early alarm of water removal, self-control of oil temperature, air discharge, oil pumping and the like; and the fuel filer device has the characteristics of compact structure, low price, convenience for installation, high reliability and the like.
Description
Technical field
The utility model relates to a kind of cascaded structure fuel oil filter device, belongs to engine fuel filter design field.
Technical background
At present, strict emission regulation demands diesel engine high-pressure system provides higher jet pressure, and this has just proposed challenge to the reliability of injection system.The component failure of injection system mainly comes from corrosion and wearing and tearing, except the internal factor of material own, the physical parameters such as the particle concentration of its external factor particulate matter impurity, particle size can be brought direct abrasion of particles to fuel injection system, thereby have a strong impact on the qualities such as reliable durable of engine emission index, power character, economical and car load.High-pressure system is presented as finally that to the fuel filter technical requirements complete machine and end user are to the expected value of machine life, and the feedback result that comes into operation in the computer system market has proposed further higher requirement to filtering technique, require the hand oil pump reliable operation, the pump oil mass is large, and suction force is strong; Filter efficiency is high, and the life-span is long; It is convenient to control, and maintenance is changed convenient, compact structure.
Summary of the invention
The purpose of this utility model is to provide a kind of cascaded structure fuel oil filter device, improves the hand oil pump reliability, improves the efficient of filtrating equipment, prolongs filter working life, and optimizing structure design ensures that maintaining is convenient and swift; Optimal design by base makes compact structure, reduces assembly at the space hold of car load.
The technical solution of the utility model is achieved in that a kind of cascaded structure fuel oil filter device, formed by base, plunger type hand oil pump, fuel preliminary filter, secondary fuel oil filter, fuel preliminary filter heater, secondary filter heater, integrated water level alarm, it is characterized in that: the fuel oil filter assembly that is made of series connection fuel preliminary filter and secondary fuel oil filter is fixedly connected on the base, and the plunger type hand oil pump is connected to the rear end of fuel preliminary filter; Fuel preliminary filter and secondary fuel oil filter are equipped with fuel preliminary filter heater and secondary filter heater, and the fuel preliminary filter front end is equipped with integrated water level alarm.
Good effect of the present utility model is the optimal design by base, hand oil pump is designed into the rear end of fuel preliminary filter, improves the reliability of fuel strainer when improving the hand oil pump reliability; The plunger type hand oil pump of design strengthens rapidly every stroke pump oil mass and ability strengthens, and promotes the performance satisfaction of filtrating equipment; The fuel oil filter assembly of series connection, the Proper Match filter efficiency further improves the filter efficiency of device, prolongs the working life of filter.The heater design of integrated temperature control switch is independently controlled the assembly of devices temperature, simplifies control strategy.Integrated electronic Water-level alarm switch assembly is convenient to maintaining.Optimizing structure design makes cleaner structure compact, and maintaining is convenient and swift.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described: as shown in Figure 1, a kind of cascaded structure fuel oil filter device, formed by base 1, plunger type hand oil pump 2, fuel preliminary filter 3, secondary fuel oil filter 4, fuel preliminary filter heater 5, secondary filter heater 6, integrated water level alarm 7, it is characterized in that: the fuel oil filter assembly that is made of series connection fuel preliminary filter 3 and secondary fuel oil filter 4 is fixedly connected on the base 1, and plunger type hand oil pump 2 is connected to the rear end of fuel preliminary filter 3; Fuel preliminary filter 3 and secondary fuel oil filter 4 are equipped with fuel preliminary filter heater 5 and secondary filter heater 6, and the front end of fuel preliminary filter 3 is equipped with integrated water level alarm.
Optimal design by base 1, plunger type hand oil pump 2 is designed into the rear end of fuel preliminary filter 3, avoid the particulate matter impurity in the fuel oil to cause that plunger type hand oil pump 2 lost efficacy, and improved the reliability of fuel strainer when improving plunger type hand oil pump 2 reliabilities.
Adopt 2 designs of plunger type hand oil pump, every stroke pump oil mass is strengthened rapidly and the ability enhancing, promote the performance satisfaction of filtrating equipment; The fuel oil filter assembly that adopts fuel preliminary filter 3 to connect with secondary fuel oil filter 4, not only the moisture in the filtering fuel oil can filter out the granule foreign in the fuel oil simultaneously, the Proper Match filter efficiency, further improve the filter capacity of device, prolong the working life of filter.
Integrated water level alarm assembly 7 maintains easily.
