Interlayer type multi-functional bearing pedestal for Roots blower

Abstract

The invention discloses an interlayer type multi-functional bearing pedestal for a Roots blower, which comprises a bearing pedestal body; countersunk head plug holes, an air flow channel and two bearing holes are formed in the bearing pedestal body; the countersunk head plug holes consist of two flow channel upper countersunk head plug holes, two flow channel lower countersunk head plug holes, an upper countersunk head plug hole, a lower countersunk head plug hole, a left countersunk head plug hole and a right countersunk head plug hole; the upper countersunk head plug hole, the lower countersunk head plug hole, the left countersunk head plug hole and the right countersunk head plug hole are distributed on the edge of the air flow channel in sequence; the two flow channel upper countersunk head plug holes are distributed at the inner sides of the upper parts of the two bearing holes; and the two flow channel lower countersunk head plug holes are distributed at the outer sides of the lower parts of the two bearing holes. The interlayer type multi-functional bearing pedestal has the beneficial effect that after one-time processing, the different countersunk head plug holes are blocked by countersunk head plugs to realize different distribution of air cavities, air passages and water channels , so that the same Roots blower realizes the multiple applications of water cooling, air cooling, vacuum countercurrent cooling and the like according to the different requirements, and the heat radiation effect is better.

Description

technical field [0001] The invention relates to a bearing seat, in particular to a sandwich type multifunctional bearing seat for a Roots blower (Roots vacuum pump). Background technique [0002] Roots blower (Roots vacuum pump) is a pneumatic source equipment and vacuum equipment widely used at home and abroad. The equipment generates a lot of heat when compressing air (or vacuuming). After the heat is transferred to the bearing, the bearing is easily burned in a high-temperature environment, resulting in product damage. This situation has become the main reason for limiting the service life of the Roots blower. Therefore, the body of the Roots blower (Roots vacuum pump) is largely designed around cooling and heat dissipation. [0003] Currently on the market, there are several cooling methods for Roots fans (Roots vacuum pumps): I. Water cooling; II. Open natural cooling; III. Forced air cooling; IV. Countercurrent cooling. [0004] I. General design of the bearing seat ...

Problems solved by technology

[0012] IV. The countercurrent cooling method is more commonly used in the vacuum market at present. Its disadvantage is that it needs to customize a special product body, and open holes from both sides of the body to introduce external air, which increases the noise. Components, complex structure, high cost

And it can only make the Roots vacuum pump reach the normal temperature of the Roots blower, and it is of little significance for the temperature drop of the Roots blower when it is used under positive pressure.
