(4) complex structure, assembly technology is numerous and diverse, and during assembling, slightly deviation easily causes oil bath air cleaner to be collaborated, and damages motor; Waste a large amount of human and material resources simultaneously.
Summary of the invention
Object of the present invention is exactly in order to address the above problem, provide a kind of without inner chamber, centrifugal pre-separating oil bath air cleaner, this device keeps the versatility of original oil bath air cleaner, and improves it and use drawback under exceedingly odious weather, environment, improves the ambient adaptability of vehicle.
To achieve these goals, the present invention adopts following technological scheme:
A kind of without inner chamber, centrifugal pre-separating oil bath air cleaner, comprise air outlet, suction port, oil sump, filter core and integrated type shell, wherein, integrated type shell comprises inside and outside two-layer, and internal layer agrees with in edge with outer, is the annular air channel of hollow between skin and internal layer, air outlet is arranged on the internal layer of integrated type shell, suction port is arranged on the skin of integrated type shell, and oil sump is installed on integrated type shell internal layer lower end, and filter core is arranged at the inside of integrated type shell internal layer; Oil sump comprises oil groove and dust storage groove; The side of oil sump is provided with automatic blowdown valve; Filter core comprises the chain link fence of three layers of different densities, along the inwall of integrated type shell internal layer, is evenly horizontally disposed with.
Three layers of chain link fence of described filter core are arranged in order from top to bottom by the ascending inwall along integrated type shell of density.
Described integrated type shell is long-round-shape or circle, wherein, is oblongly defined as the integrally closed figure that two ends are relative circular arcs, centre is two parallel lines head and the tail connect to form.
When described integrated type shell is long-round-shape, for large flow oil bath air cleaner.
When described integrated type shell is circular, for small flow oil bath air cleaner.
Described integrated type shell is that integral molded plastic or iron sheet are welded.
Working principle of the present invention is: adopt integrated type shell, and form annular air channel between its internal layer and skin, so both strengthened the area of air flue, utilize air to enter air flue is the centrifugal force that eddy flow produces simultaneously, and large particle dust and water droplet are separated; Oil sump is divided into oil groove and dust storage groove two-part, inside groove is that oil groove filling machine oil serves as filter medium, and water jacket is dust storage groove, because centrifugal force separate large particle dust and water droplet out falls into wherein, so just avoided entering in machine oil, improved the applicable time of machine oil; Oil sump lateral layout automatic blowdown valve, in the closed position because of suction function valve during motor operation, when the impurity in engine stop or dust storage groove reaches certain pressure, valve body automatically open with atmosphere be connected, blowdown, guarantee that oil bath air cleaner still can normally work under the exceedingly odious environment such as sleety weather, improved the environmental suitability of car load.
Beneficial effect of the present invention is:
1, solve the vehicle problem that oil bath air cleaner easily lost efficacy during automobilism under rain, snow weather, separated in time and discharged moisture, guaranteed the normal operation of vehicle;
2,, under the larger environment of haze, dust, in time by dust separation and emit, guaranteeing that the machine oil energy long period is used did not lose efficacy;
3, three grades of filter cores that adopt annular air channel and different densities, intake resistance has reduced 40%, promotes the useful horsepower of motor, reduces oil consumption, reduces and pollutes;
4, adopt integrated type shell mechanism, without inner chamber, reduced load module and assembly process.
