Abstract

Ventilated cap, particularly a kind of dust-proof, waterproof, anti-overflow, disassembled cleaning type Ventilated cap, be made up of block, sleeve pipe, wire gaze, sponge, perforated baffle, mariages pipe, non-removable parts are formed on the bottom of perforated baffle welded and installed in block.The sleeve pipe that wire gaze is equipped with in inside is arranged in the pipe of mariages pipe, and perforated baffle, sponge order are sleeved on mariages pipe and form dismountable parts.Mariages pipe forms with the perforated baffle screwed connection in block the dismountable entirety sealed.The ventilative of large pump bearing can be widely used in, also may be used for the ventilative of gear-box.

Description

Ventilated cap

Technical field:

The utility model relates to Ventilated cap, particularly a kind of dust-proof, waterproof, anti-overflow, disassembled cleaning type Ventilated cap.

Technical background:

In prior art, the bearing place of large pump generally adopts disc to drive the lubricating system of lubricant oil, because rotating speed is very high, temperature in bearing housing is very high, if use general Ventilated cap that the mist of oil in bearing housing can be made to be mingled with to discharge outside case in the gas flow, cause environmental pollution, under the drive of disc, lubricant oil has splash phenomena simultaneously, if use the lubricant oil that general Ventilated cap splashes can overflow from Ventilated cap, cause environmental pollution.Large pump is generally arranged in builder's temporary shed, during heavy rain strong wind weather, the horizontal rainwater that strong wind causes can drop on Ventilated cap place, if use general Ventilated cap, because the air intake-exhaust mouth of Ventilated cap is in same level, though there be blocking of filter dirt material, the a small amount of rainwater splashed still can be flow in bearing housing by Ventilated cap, if moisture rising in lubricant oil, reduces the performance of oil product, accelerate the aging speed of oil product, potential threat is caused to bearing.General Ventilated cap, due to structure, can not be disassembled after its filter dirt material contamination damages and to change or clean, need integral replacing, cause need not user cost expenditure.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned deficiency, thus provides a kind of special Ventilated cap of large pump bearing.Ventilated cap can disassemble more renew cartridge, and it not only has effect of dust-proof air ventilation, can also effectively stop the excessive of oil, mist of oil, have effect of waterproof simultaneously, eliminate the potential threat caused bearing, avoid environmental pollution.

The utility model be achieved in that Ventilated cap by blocking a shot, sleeve pipe, wire gaze, sponge, perforated baffle, mariages pipe form.It is characterized in that the sleeve pipe that wire gaze is equipped with in inside is arranged in the pipe of mariages pipe, perforated baffle, sponge order are sleeved on mariages pipe, the bottom of perforated baffle welded and installed in block, mariages pipe and the perforated baffle screwed connection in block.During Ventilated cap work, air enters bearing housing by the filtration of sponge or other filter dirt material, has effect of dust-proof air ventilation.During heavy rain strong wind weather, first a small amount of rainwater of splashing has blocking of sponge, and the air intake-exhaust mouth of Ventilated cap, not in same level, therefore has effect of waterproof.When the lubricant oil splashed in bearing housing, mist of oil are outwards overflowed by mariages pipe, because blocking of wire gaze can make a part of oil molecule adsorb on a wire mesh, accumulate larger oil droplet on its surface by tiny oil droplet and be back to bearing housing, therefore there is anti-overflow effect.Mariages pipe can be for convenience detach with the perforated baffle screwed connection in block, conveniently cleaning can be taken out in the pipe that the sleeve pipe that wire gaze is equipped with in inside is arranged on mariages pipe, and perforated baffle, sponge are sleeved on mariages pipe, also conveniently can take out and change sponge, therefore its filter core can be disassembled after polluting and damaging and change or clean, do not need integral replacing, save user cost.Therefore in sum, the utility model can disassemble more renew cartridge, and it not only has effect of dust-proof air ventilation, can also effectively stop the excessive of oil, mist of oil, have effect of waterproof simultaneously, eliminate the potential threat caused bearing, avoid environmental pollution.The utility model can be widely used in the ventilative of large pump bearing, also may be used for the ventilative of gear-box.

Accompanying drawing illustrates:

Below in conjunction with accompanying drawing, the utility model is further illustrated

Accompanying drawing 1 is cut-away view of the present utility model

Accompanying drawing 2 is that A, A amplify diagram of bowing

In accompanying drawing 1, sleeve pipe, 2, wire gaze, 3, sponge, 4, perforated baffle, 5, mariages pipe, 6, block, 7, relief opening, 8, suction port.

Embodiment;

In accompanying drawing, Ventilated cap is made up of sleeve pipe (1), wire gaze (2), sponge (3), perforated baffle (4), mariages pipe (5), block (6), and non-removable parts are formed on the bottom of perforated baffle (4) welded and installed in block (6).The sleeve pipe (1) that wire gaze (2) are equipped with in inside is arranged in the pipe (5) of mariages pipe, is sleeved on that mariages pipe (5) is upper forms dismountable parts by the relief opening (7) of perforated baffle (4), sponge (3) order.Mariages pipe (5) forms with relief opening (7) screwed connection of block (6) interior perforated baffle (4) the dismountable entirety sealed. and air enters bearing housing through suction port (8), sponge (3), wire gaze (2).

Claims

1. Ventilated cap by blocking a shot, sleeve pipe, wire gaze, sponge, perforated baffle, mariages pipe form, it is characterized in that the sleeve pipe that wire gaze is equipped with in inside is arranged in the pipe of mariages pipe, perforated baffle, sponge order are sleeved on mariages pipe and form dismountable parts, non-removable parts are formed on the bottom of perforated baffle welded and installed in block, and mariages pipe forms detachable entirety with the perforated baffle screwed connection in block.
