Description
Technical field
The utility model belongs to blower fan field, particularly relates to a kind of multistage centrifugal blower.
Background technique
A kind of multistage centrifugal blower not having thin oil lubricant, all the time insufficient lubrication is there is by grease lubrication, the reason such as be often out of order, user feels bad for this reason, its main cause is the hot operation of grease after some months, the grease of bearing race is made progressively to become aging, viscosity degree reduces, bearing roller also progressively forms dry grinding phenomenon, go to work braving one's illness and both make user annotate new grease to bearing in time, also cannot retrieve the bearing before not damaged, continue use and go down, finally cause stopping production, causing economic loss to user.
Summary of the invention
The utility model is to provide that a kind of fuel feeding is reliable, the multistage centrifugal blower of thin oil lubricant.
The purpose of this utility model is achieved in that described
multistage centrifugal blower, comprise casing, main shaft, fore bearing pressing plate, round nut, front fuel tank, front shaft sleeve, front disc, water-cooling bearing block, closely afterwards in utero to overlap, rear close palace overcoat, another round nut, close palace overcoat, gland, rear fuel tank, another round nut, rear axle housing, deep groove ball bearing, outside framework oil seal, rear bearing block, exhaust seat, impeller and air inlet seat, its feature is that the middle section that described impeller is contained in main shaft forms rotor set, rotor assembling is in casing, casing two ends load onto air inlet seat and exhaust seat respectively, water-cooling bearing block is loaded onto respectively in air inlet seat and exhaust seat two ends, the bearing position of main shaft two ends and water-cooling bearing block is equipped with bearing and round nut respectively, and the bearing at two ends is compressed respectively with fore bearing pressing plate and rear bearing pressing plate, disc and flinger ring and front shaft sleeve before front-end of spindle is loaded onto, and after the rear end of main shaft is loaded onto close palace overcoat and rear close in utero cover and another round nut, rear axle housing and rear disc and another round nut is loaded onto at water-cooling bearing block and main the tip of the axis, front fuel tank and rear fuel tank are contained on fore bearing pressing plate and rear bearing pressing plate respectively, and load onto oil ga(u)ge at front fuel tank and rear fuel tank.So that filling and inspection oil lubrication situation.
The two ends and water-cooling bearing block of main shaft are separately installed with outside framework oil seal and seal ring assembly.
The utility model has following four large advantages: 1) be with oil lubrication: the utility model multistage centrifugal blower is innovative design on the basis of conventional multi-level centrifugal blower.New blower lubrication system adds fuel tank and water-cooling bearing block, and fuel tank adopts in spilled oil formula lubrication, fuel tank and adds band disc device, and the effect of band disc is that when fuel tank position can be made lower slightly, bearing lubrication also can obtain and ensure.2) be strictly on guard against leakage of oil: also can set up flinger ring in the outlet port of front fuel tank main shaft, when spilled oil at full speed is got rid of into oil tank wall, oil dripping gets rid of into reservoir port U-groove bevel through flinger ring, finally flows back in oil sump, reaches oil tight object.3) high sealing, heat insulation, trapping: for guaranteeing lubricants capacity and oily permanency in fuel tank, prevent high-temperature gas from immersing in fuel tank, the cooling water flow conduits in bearing support Front-end Design, utilize cooling water that the rolling bearing at a high speed is not easily generated heat, and set up seal ring assembly in the rear end of bearing support, high-temperature gas barrier can be made like this in great bell, effectively improve the working life of bearing and guarantee that oil is constant.4) energy-conservation: common high-temperature grease lubrication, load has the factor gone to work braving one's illness, and energy consumption aspect is also higher than lubricant oil blower 3%-5%, and therefore new low-temperature lubrication system, achieves light load and well run, and reduces energy consumption, reaches energy-conservation object.
