Abstract
The utility model discloses a centrifuge spindle seal assembly comprising a base, a centrifuge drum and a spindle. The spindle is disposed on the base vertically; the centrifuge drum is sleeved on the upper end of the spindle; a protection sleeve is sleeved on a middle bare part, which is at the bottom of the centrifuge drum, of the spindle; the upper end of the protection sleeve is inserted in a slot in the upper surface of the centrifuge drum; a bearing is disposed between the spindle and the base; a dustproof seal ring is installed on the upper end of the bearing; and the inner wall of the dustproof ring is provided with a double-layer dustproof lip made of oil resistant rubber. According to the centrifuge spindle seal assembly, the bare part of the spindle is isolated and prevented from being contacted with outside world, and each seal ring shields the spindle from corrosive gas and liquid and achieves a protection effect.
Description
Technical field
The utility model relates generally to the centrifuge field, relates in particular to a kind of centrifuge principal axis seal assembly.
Background technology
Centrifuge is mainly used in chemical field, and main shaft generally adopts carbon steel or steel alloy, is exposed in the corrosive gas throughout the year, very easily produces corrosion, causes security incident.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of centrifuge principal axis seal assembly to be provided.
The utility model is achieved through the following technical solutions:
A kind of centrifuge principal axis seal assembly; including base, bowl, main shaft, described main shaft vertically places on the base; the upper end of main shaft is set with bowl; it is characterized in that: be positioned on the middle exposed part of main shaft of bowl bottom and be set with a protective sleeve; the upper end of described protective sleeve is inserted in the slot of bowl lower surface; between described main shaft and the base bearing is installed; the upper end of described bearing is equipped with dust-proof seal ring; have double-deck dust excluder lips on the inwall of described dust ring, and dust excluder lips adopts oil resistant rubber to make.
Bring out bowl on the described main shaft, and at external part gland is installed.
The utility model has the advantages that:
The utility model is isolated the exposed part of main shaft; do not produce with the external world and contact; each sealing ring completely cuts off corrosive gas, liquid; reach the protection effect; and structure of the present utility model is made improvement on the basis of traditional structure; cancelled the bowl bottom surface and adopted bolt to be fixedly connected with mode, so that install and use convenient.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1; a kind of centrifuge principal axis seal assembly; include base 1; bowl 2; main shaft 3; described main shaft 3 vertically places on the base 1; the upper end of main shaft 3 is set with bowl 2; be positioned on the middle exposed part of main shaft of bowl 2 bottoms and be set with a protective sleeve 4; the upper end of described protective sleeve 4 is inserted in the slot 5 of bowl lower surface; between described main shaft 3 and the base 1 bearing 6 is installed; the upper end of described bearing 6 is equipped with dust-proof seal ring 7; has double-deck dust excluder lips 8 on the inwall of described dust ring 7; and dust excluder lips 8 adopts oil resistant rubber to make; bring out bowl 2 on the described main shaft 3, and at external part gland 9 is installed.
