Abstract

The invention relates to an oil-water separator which comprises a rectangular seal ring, a thread cover plate part, a rubber gasket, a diffusion cone, an O-shaped seal ring, a filter element part, a bracket connector, a shell and a water collection cup part, wherein a blade ring is arranged between the thread cover plate part and the diffusion cone. Due to the adoption of the structure of the oil-water separator, the oil-water separation efficiency of the oil-water separator is remarkably improved, the performance is stable, and the operation need of an automobile engine is met.

Description

A kind of oil and water seperator

Technical field

The invention belongs to the motor car engine part field, particularly the oil and water seperator used of a kind of motor.

Background technique

Oil and water seperator belongs to parts of engine fuel oil system, and cardinal principle is the density difference according to water and fuel oil, utilizes sedimentation theory to remove the separator of large granular impurity and moisture content, and inner also have diffusing cone, filter screen etc. to separate element.If it is clean that the diesel oil the inside has water or impurity not to filter, can cause the formation of the plunger coupled parts in oil nozzle wearing and tearing and pull, stuck up to oil sprayer.The oil sprayer damage can cause motor to accelerate unstable or accelerate unablely, perhaps discharges faults such as black smoke, influences the normal operation of vehicle.State's three emission standards are to the requirement of fuel pressure, and the moisture of filter cleaner requires to reach 95% from efficient, but many strainers can not reach such filtering effect, and time one length will cause damage to motor, is badly in need of a kind of new and effective oil and water seperator.

Summary of the invention

The object of the present invention is to provide a kind of design of new and effective compound oil and water seperator, reduce the available engine oil supply system because of the maintenance cost of component corrosion and oil pump and nozzle wear, improve the working life of motor, reduce the pollution of atmosphere that the harmful matter because of motor vehicle exhaust emission causes.

For achieving the above object, the present invention adopts following scheme:

A kind of oil and water seperator, comprise rectangular seal, thread plate parts, rubber washer, diffusing cone, O-ring seals, filter element part, carriage joint, shell and ponding cup parts, it is characterized in that, between thread plate parts and diffusing cone, be provided with blade ring.

Described blade ring is circular, is evenly distributed with several perforates at the annulus place, and the dihedral vane of direction unanimity is arranged under the perforate; Blade ring is arranged on the top of diffusing cone.

The working principle of this invention is: when engine operation, effect by input pressure at first enters blade ring with pressure oil, leading role by blade ring, make fuel oil rush at the housing outer wall, the part water droplet can be adsorbed on the housing, simultaneously because the inertial force effect, oil circuit can turn to and be flushed on the diffusing cone, because water is different with the density of oil, under action of centrifugal force, bigger water droplet is thrown to again on the inner walls and under the effect of gravity and is deposited to housing bottom, indissociable water droplet can flow to cartridge surface with oil, by filter paper water droplet and particle are tackled, the part granule foreign is adsorbed on the filter paper surface again, and the part granule foreign is deposited under the effect of gravity in the ponding cup of housing bottom along the filter paper surface with water droplet.

The present invention adopts the combined type resolution element to carry out the thorough separation of oil/water, and its advance shows as oil/moisture and significantly improves from efficient, and stable performance; According to the ISO4020 standard testing, the efficient that adopts the oil-water separation of single diffusing cone is 70% ~ 80%, the efficient of single filter paper oil-water separation is 60% ~ 70%, contaminant filter efficient reaches 80%, be 98.5% and adopt the efficient of this new and effective compound oil-water separation, contaminant filter efficient reaches more than 93%.

Embodiment

The present invention will be further described in detail below in conjunction with embodiment and accompanying drawing thereof:

As shown in Figure 1, a kind of oil and water seperator comprises rectangular seal 1, thread plate parts 2, sealing gasket 10, blade ring 4, diffusing cone 5, O-ring seals 9, filter element part 6, carriage joint 7, shell 3, ponding cup parts 8.

Described thread plate parts 2 middle parts are provided with screw 21, and periphery is provided with rectangular seal 1, the sealing that can spin with the bottom surface of filter block, and several oil inlet holes 22 that evenly distribute on the disc between screw 21 and the seal ring 1, thread plate parts 2 are connected with shell 3 tops.

Described shell 3 inside, the bottom of thread plate parts 2 is by sealing gasket 10 and diffusing cone 5 pressings, diffusing cone 5 tops are connected with blade ring 4, diffusing cone 5 bottoms are by O-ring seals 9 and filter element part 6 pressings, filter element part 6 bottoms are provided with carriage joint 7, carriage joint 7 is positioned at the bottom of shell 3, and the threaded end of carriage joint 7 bottoms stretches out shell 3.

After spinning, the threaded end of described ponding cup parts 8 and carriage joint 7 bottoms is fixedly mounted on the shell 3.

As shown in Figure 2, described blade ring 4 is circular, is evenly distributed with 12 perforates 41 at annulus disc place; As shown in Figure 3, Figure 4, perforate has the dihedral vane of direction unanimity for 41 times.

Above-described only is preferred implementation of the present invention, should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the principle of the invention, can also make some modification and improvement, and these also should be considered as belonging to protection scope of the present invention.

Claims

1. oil and water seperator, comprise rectangular seal, thread plate parts, rubber washer, diffusing cone, O-ring seals, filter element part, carriage joint, shell and ponding cup parts, it is characterized in that, between thread plate parts and diffusing cone, be provided with blade ring; Described blade ring is circular, and the place is evenly distributed with several perforates at the annulus disc, and the dihedral vane of direction unanimity is arranged under the perforate; Blade ring is fixedly installed on the top of diffusing cone.
