Abstract
The utility model discloses a cooling device of multistage centrifugal fan bearing box belongs to the chemical industry equipment field. This is the equipment with coolant oil cooling bearing case. Have on multistage centrifugal fan's bearing box into that oil pipe inserts wherein, insert advancing of bearing box have on the oil pipe about two nozzles respectively facing to the raceway of incasement bearing, the other end that advances oil pipe goes out oil pipe with motor drive's oil pump and meets in the oil tank. There are an oil pipe and the oil tank of area heat dissipation wing to meet on the bearing box. The coolant oil sprays the raceway of bearing rolling element motion fast for the cooling device of multistage centrifugal fan bearing box, directly takes away the heat, and the coolant oil that returns looses the heat for the atmosphere under the effect of oil tank heat dissipation wing. Guarantee that the bearing box temperature is in being less than 65 DEG C of normal range.
Description
Technical field
The utility model belongs to field of chemical equipment, especially a kind of cooling unit.
Background technique
It is the production process realizing carbolineum cracking under producing 1900 degree of high temperature conditions by combustion of natural gas that high-carbon black pigment is produced.The air quantity supply that the lytic response of carrying out in a device needs powerful Multi-stage centrifugal fan to provide enough.Bearing temperature under heavy load of blower fan can constantly raise.The conventional method reducing temperature in bearing housing, carries out heat exchange with cold water volute.But this way often can not meet normal temperature requirement lower than the condition of 65 DEG C, often makes temperature be in 90-100 DEG C.Equipment for a long time under the high temperature conditions operation can bring serious consequence.
Summary of the invention
The purpose of this utility model is to provide a kind of cooling unit of Multi-stage centrifugal fan bearing housing, and it has good intensity of cooling, ensures that bearing housing works under normal temperature conditions.
For reaching this object, have employed such technological scheme: the cooling unit of Multi-stage centrifugal fan bearing housing, is the equipment with cold oil cooling bearing case.The bearing housing of Multi-stage centrifugal fan has oil inlet pipe insert wherein, the oil inlet pipe of insertion bearing housing has upper and lower two nozzles respectively facing to the raceway of case inner bearing, the other end of oil inlet pipe connects with motor-driven oil pump outlet line in fuel tank.Bearing housing there is oil outlet tube connect with fuel tank.
The injection diameter of two nozzles on oil inlet pipe is 2 millimeters.
The tank wall of fuel tank there is radiating fin.
The cooling unit cold oil of Multi-stage centrifugal fan bearing housing sprays the raceway of bearing roller motion fast, and directly heat is taken away, heat falls apart to air by the cold oil returned under the effect of fuel tank radiating fin.Ensure that bearing housing temperature is lower than in 65 DEG C of normal range (NR)s.
Accompanying drawing illustrates: the structural representation of the cooling unit of Fig. 1 Multi-stage centrifugal fan bearing housing.
Embodiment: be further described below in conjunction with accompanying drawing.
As shown in drawings, the cooling unit of Multi-stage centrifugal fan bearing housing is the equipment with cold oil cooling bearing case.The bearing housing 2 of the Multi-stage centrifugal fan 8 driven by motor 1 there is oil inlet pipe 3 to insert wherein, there are upper and lower two nozzles 10 the oil inlet pipe end of inserting in bearing housing respectively facing to the raceway of case inner bearing 9, and the oil pump outlet line that the other end of oil inlet pipe drives with motor 4 in fuel tank 6 is connected.Oil outlet tube 7 on bearing housing connects with fuel tank.Under the effect of oil pump, two nozzles 10 that the cold oil in fuel tank is two millimeters from injection diameter spray to bearing race fast, are taken away by the heat of generation.The cold oil completing heat exchange returns fuel tank from oil outlet tube.The tank wall of fuel tank 6 there is radiating fin 5, the heat of fuel tank is fallen apart to air.The heat transfer process of cooling unit ensure that the normal working temperature of Multi-stage centrifugal fan bearing housing.
