Abstract
A kind of stirring type disc, comprise cirque body, described cirque body has the vane group that at least 3 groups can increase whipping lubricant oil active force, to realize bearing housing internal lubrication oil in atomize, got rid of fully by lubricant oil on bearing, the utility model compared with prior art has and significantly improves bearing lubrication effect, improves the working life of bearing, ensure the overall operation of centrifugal pump, reduce the advantages such as the spoilage of pump entirety.
Description
Technical field the utility model relates to a kind of parts of centrifugal pump, particularly relates to a kind of lubricating component.
Background technique centrifugal pump is a kind of pump being widely used in the fields such as electric power, metallurgy, coal, building materials, at present, centrifugal pump all needs bearing to support, so the protection of bearing and lubrication become particularly important, at present bearing working life of general centrifugal pump is generally at about 1 year or less than 1 year, but some chemical industry centrifugal pumps especially carry should be 25000 hours the working life of the centrifugal pump of high temperature media then regulation bearing, about about 3 years.Current centrifugal pump working life shorter reason to comprise axle precision inadequate, coupling misalignment, think that mounting type is not reciprocity, in addition, the reason of an outbalance is that bearing lubrication not fully causes burn-out of bearing, for auxiliary bearing lubrication, the measure taked at present is in bearing housing, set up the disc be enclosed within pump shaft, traditional disc is single cirque body, it is in the process of practical application, because when pump operates, disc role is very little, can not fully lubricant oil be thrown on bearing, lubrication and the cooling-down effect of bearing are poor, long-time use will affect the life-span of bearing, so that cause the damage of bearing, if bearing damage, pump cannot normally run, great loss is brought to actual production, and change bearing not only add greatly cost drop into, and due to the reason of environment, install and operate very difficult.
Summary of the invention the purpose of this utility model is to provide a kind of stirring type disc, and lubricant oil can get rid of on bearing by this disc fully, and bearing bearing is lubricated fully.
The utility model is still arranged in bearing housing, and be enclosed within pump shaft and follow pump shaft rotation, technological scheme is as follows:
The utility model still includes cirque body, this cirque body is same as the prior art, described cirque body has the vane group that at least 3 groups can increase whipping lubricant oil active force, to realize bearing housing internal lubrication oil in atomize, lubricant oil is got rid of fully on bearing.
Described vane group generally has 3 groups or 4 groups, and often group has two strip blades, and these two blades are arranged in a crossed manner, and each blade and toric outer peripheral surface are vertical setting.
The blade of described each vane group is preferably axially arranged in distorted shape along cirque body.
The utility model can followed by pump shaft in bearing housing inner rotation, drive lubricant oil to spray to two side bearings simultaneously, because disc is not be fixed on axle, and blade angle is designed to distortion formula, reduce resistance, such disc just can under the drive of axle normal rotation, but also too many air horsepower can not be consumed, blade is under High Rotation Speed state, by the active force that blade outwards gets rid of, lubricant oil is splashed on bearing and cabinet wall, lubricant oil fully can be stirred, make in bearing housing oily close to mist of oil state, so just can carry out sufficient lubrication to bearing, lubrication effect improves greatly, if do not have external factor to affect, bearing can increase working life greatly.This disc can adopt integral molded plastic method to manufacture, and vane group and cirque body form integral structure, the simple and reliable in quality of structure, and material can select teflon material, effective, cost is low.
The utility model compared with prior art tool has the following advantages:
1, when consuming pump shaft power and being very little, make bearing housing internal lubrication oil be sprayed on bearing, make bearing absorb lubricant oil more abundant, significantly improve bearing lubrication effect, improve the working life of bearing.
2, ensure the overall operation of centrifugal pump, reduce the spoilage of pump entirety, while cost-saving input, reduce the inconvenience that maintenance brings.
Description of drawings 1 is that the master of embodiment 1 looks generalized section.
Fig. 2 is the vane group schematic diagram of embodiment 1.
Fig. 3 is that the master of embodiment 2 looks generalized section.
Next embodiment just elaborates to the utility model by reference to the accompanying drawings
Embodiment 1
A kind of stirring type disc, as depicted in figs. 1 and 2, comprise cirque body 1, described cirque body is provided with 4 groups of vane group be connected as a single entity with it 2, and these 4 vane group are distributed on toric outer peripheral surface; Described each vane group all has two strip blades 2 ' arranged in " X " shape, and wherein each blade is all vertical with toric outer peripheral surface is arranged; The blade of described each vane group is all axially arranged in distorted shape along cirque body.
Embodiment 2
A kind of centrifugal pump of Application Example 1, as shown in Figure 3, this centrifugal pump is existing chemical centrifugal pump, main structure is: support underframe 2 is established in the pump housing 1 lower end being provided with fluid inlet and outlet, the inside of the pump housing is provided with impeller 3, impeller is fixed on the front end of horizontal pump shaft 4, pump shaft is successively through the link press span 5, the bearing housing 6 that are positioned at pump housing rear portion, described pump shaft connects with the front roll bearing 7 of bearing housing inside, rear rolling bearing 8 respectively, support underframe 9 is established in bearing housing lower end, the rear portion of impeller is provided with the pump cover 10 be enclosed within pump shaft, and pump cover is located by link press span and the pump housing; Have the disc 11 be enclosed within pump shaft in described bearing housing, this disc is arranged between the front roll bearing of bearing housing and rear rolling bearing, and the cirque body internal diameter of disc is greater than the diameter of axle of pump shaft part between described forward and backward rolling bearing.
