Abstract
The utility model discloses a bearing body part for a petrochemical process pump, which comprises a bearing box body and a main shaft, wherein the main shaft is installed in the bearing box body, and both ends of the main shaft extend out of the bearing box body. The utility model adopts the structure that a cuboid oil storage chamber is arranged at the inner side of the bearing box body and a plurality of parallel strip-shaped radiating ribs are arranged on the outer surface of the bearing box body, and can well solve the temperature rise and abrasion problems of a bearing.
Description
Technical field:
The utility model relates to the chemical pump field, specifically is a kind of bearing body part that is used for petrochemical process pump.
Background technique:
The operational condition of pump is often very harsh in petrochemical industry is produced, and high temperature media and cryogenic media have.For example in heat-conducting oil heating system, the operating temperature of Heat-transfer Oil Pump is everlasting about 300 ℃, the operating temperature of the pump that has even can reach 450 ℃.In addition, when state medium such as conveying liquid nitrogen, liquid oxygen, the low-temperature working temperature of pump all will be below-20 ℃, and what have reaches below-100 ℃.Petrochemical process pump is when operation, and it is bad because of the bearing support temperature variation bearing lubrication to take place through regular meeting, bearing race, and ball, the wearing and tearing of retainer are difficult to problems such as normal operation.Original accumulator is less cylindrical of volume, oily temperature rise too fast.The utility model adopts the bearing housing inboard to be provided with the cuboid shape accumulator, and the bearing housing outer surface is provided with several parallel bar shaped radiating fin, and it can solve the temperature rise and the wear problem of bearing well.
The model utility content:
The purpose of this utility model provides a kind of bearing body part that is used for petrochemical process pump, the thermal expansion and the wear problems that have overcome the temperature difference of existing bearing housing structure and produced, it is simply compact to be not only pump structure, stability is high, it is little to take up room, and convenient for installation and maintenance, long service life.
The technical solution of the utility model is as follows:
A kind of bearing body part that is used for petrochemical process pump, comprise bearing housing, main shaft, described main shaft is installed in the bearing housing, bearing housing is stretched out at the main shaft two ends, it is characterized in that: be provided with the accumulator of cuboid shape in the described bearing housing, the bearing housing outer surface is provided with several parallel bar shaped radiating fin.
The utility model has the advantages that:
The utility model adopts the bearing housing inboard to be provided with the cuboid shape accumulator, and the bearing housing outer surface is provided with several parallel bar shaped radiating fin, and it can solve the temperature rise and the wear problem of bearing well.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
A kind of bearing body part that is used for petrochemical process pump, comprise bearing housing 1, main shaft 2, main shaft 2 is installed in the bearing housing 1, and bearing housing 1 is stretched out at main shaft 2 two ends, be provided with the accumulator 3 of cuboid shape in the bearing housing 1, bearing housing 1 outer surface is provided with several parallel bar shaped radiating fin 4.
