The technical scheme of the utility model is realized like this:
the utility model provides a leak protection oil ventilative lid for slurry pump, includes ventilative lid body, the lower extreme of ventilative lid body is provided with the through-hole with grease chamber intercommunication, and the axis setting of through-hole along ventilative lid body, the lower extreme of ventilative lid body is provided with the filter screen, and the upper end circumference of ventilative lid body is provided with a set of bleeder vent, a set of bleeder vent be linked together with the through-hole, the bleeder vent includes the long slope section with the through-hole intercommunication and runs through the short slope section of ventilative lid body circumference, long slope section and short slope section are linked together and are the font of falling V, this internal buffering hole that still is provided with of ventilative lid, buffering hole and bleeder vent one-to-one, the buffering hole is located the lower part of bleeder vent and is linked together with the bleeder vent, the intercommunication department of buffering hole and bleeder vent is located the long slope section of bleeder vent, the.
The buffer hole is obliquely arranged and is opposite to the inclination direction of the long inclined section of the air hole.
The buffer hole is bent at a right angle.
The top circumference of the ventilation cover body is provided with a ventilation cover brim, and the ventilation cover brim and the ventilation cover body are integrally formed and connected in a smooth and smooth manner.
The utility model has the advantages that: the air holes of the utility model are arranged obliquely to the axis, so that the lubricating oil is not easy to flow out; a buffer hole is formed below the air vent, and lubricating oil can flow into the buffer hole before flowing to the short inclined section, so that the lubricating oil cannot flow out of the air vent, and the air vent cover cannot leak oil; the bolt at the other end of the buffer hole, which is the buffer hole, can be detached so as to conveniently clean accumulated lubricating oil; the short inclined section of the air hole is inclined downwards, so that water is not easy to enter the air hole, and the water can flow out of the air hole under the action of gravity even if entering the air hole; the top of the breathable cover is provided with the brim, so that water can be further effectively prevented from entering the breathable hole, the lower end of the breathable cover body is connected with the filter screen, lubricating oil brought out from the bearing chamber passes through the filter screen to be filtered, the lubricating oil returns to the oil chamber from the filter screen, and the breathability is good.
