Abstract
A diesel prefilter assemble aims to provide a handling oil pump equipped diesel prefilter; the utility model of a diesel prefilter assemble comprises a diesel prefilter base, a shell and a screw cover plate. It is characterized in that the upper end surface of the diesel prefilter base is provided with an inserting hole in which the lower end of the handling oil pump assemble is inserted, the upper cover of the handling oil pump assemble is riveted on periphery of the inserting hole on the base, the diesel prefilter base is provided with an oil inlet and an oil outlet corresponding with the oil inlet and oil outlet provided on the handling oil pump assemble, the oil outlet of the handling oil pump is connected with the prefilter through the corresponding oil outlet on the base; the utility model makes the handling oil pump integrated on the diesel prefilter assembly so as to reduce the amount of assembly of the whole vehicle; the integrated diesel prefilter is fixed on the vehicle frame, and the utility model has advantages of spacious working space, convenient operation and maintenance.
Description
Technical field:
A kind of diesel oil prefilter of the utility model assembly relates to automobile diesel oil prefilter system.
Background technique:
At present, the low pressure oil line structure of domestic most diesel engines is that diesel oil enters the diesel oil prefilter from fuel tank through oil pipe, after filtration, the diesel oil of post precipitation enters the hand oil pump assembly, enter oil pump for engine after filtering by diesel-oil filter again, when diesel engine during at emptying gas, all be to finish by manual method of pushing hand oil pump, because present hand oil pump assembly is mounted on the motor mostly, as Cummins Engine, along with the limitation of the continuous maximization and the vehicle general arrangement of motor, user's unusual difficulty when the operator oil pump.
Summary of the invention:
The purpose of a kind of diesel oil prefilter of the utility model assembly is to propose a kind of diesel oil prefilter assembly with hand oil pump function.A kind of diesel oil prefilter of the utility model assembly is by diesel oil prefilter base, shell, thread plate constitutes, it is characterized in that, described diesel oil prefilter base upper-end surface is provided with a jack, hand oil pump assembly lower end is inserted in the described jack, and the loam cake of described hand oil pump assembly is riveted to the jack edge of base, and seals with oil-resistant seal ring.Described diesel oil prefilter base is provided with the corresponding oil inlet and outlet of filler opening and oil outlet position with the hand oil pump assembly, the filler opening of described hand oil pump is equipped with filter screen with the link position that the base filler opening communicates, and the oil outlet of described hand oil pump communicates with prefilter by the oil outlet of base correspondence.Make that the oil that pumps can be through the filtration and the moisture content precipitation of prefilter.The utility model has been cancelled the hand oil pump assembly on the motor, and it is integrated on the diesel oil prefilter assembly, has reduced the assembly quantity of car load; Described diesel oil prefilter assembly after integrated is installed on the vehicle frame, and activity space is spacious and comfortable, user's operation, easy to maintenance; Owing to be not installed in the spatial constraints on the motor, can strengthen the hand oil pump pump chamber, improve spring hardness simultaneously, improved the flow of hand oil pump and prefilter.
Description of drawings:
Fig. 1 is the partial cutaway schematic of a kind of diesel oil prefilter of the utility model assembly.
Embodiment:
As shown in Figure 1, a kind of diesel oil prefilter of the utility model assembly is by diesel oil prefilter base, shell, thread plate constitutes, it is characterized in that described diesel oil prefilter base 1 upper-end surface is provided with a jack 2, hand oil pump assembly 3 lower ends are inserted in the described jack 2, the loam cake of described hand oil pump assembly 3 is riveted to jack 2 edges of base, and seals with oil-resistant seal ring.Described diesel oil prefilter base 1 is provided with the corresponding oil inlet and outlet 4,5 of filler opening and oil outlet position with hand oil pump assembly 3, the link position that the filler opening of described hand oil pump communicates with base filler opening 4 is equipped with filter screen 6, and the oil outlet of described hand oil pump communicates with prefilter by the oil outlet 5 of base correspondence.The utility model can be integrated in positive displacement hand oil pump assembly on the base of rotation fitting type diesel oil prefilter assembly, when pressure stability, hand oil pump are not worked, the fuel inlet ball check valve of hand oil pump assembly and fuel-displaced closure of check ring, diesel oil enters the diesel oil prefilter through oil inlet pipe from fuel tank, and net filtration and moisture content post precipitation flow to diesel-oil filter again to motor from oil outlet tube after filtration; When needs emptying gas, turn on bleed screw, press the button and make the hand oil pump descent of piston, fuel inlet ball check valve is closed, diesel oil is opened out oil return check valve and is flowed into the diesel oil prefilter in motor from the hand oil pump pump chamber, release button makes piston stroking upward, fuel-displaced closure of check ring, fuel inlet ball check valve is opened, and diesel oil is gone into the hand oil pump pump chamber from oil inlet pipe through the strainer filtering of fuel inlet ball check valve is laggard.Air in oil circuit is got rid of and so forth.
Claims (2)
1, a kind of diesel oil prefilter assembly is by diesel oil prefilter base, shell, thread plate constitutes, it is characterized in that, described diesel oil prefilter base upper-end surface is provided with a jack, hand oil pump assembly lower end is inserted in the described jack, and the loam cake of described hand oil pump assembly is riveted to the jack edge of base, and seals with oil-resistant seal ring; Described diesel oil prefilter base is provided with the corresponding oil inlet and outlet of filler opening and oil outlet position with the hand oil pump assembly, and the oil outlet of described hand oil pump communicates with prefilter by the oil outlet of base correspondence.
