Background technique
Guide bearing is the main easily worn part of pump, and especially for water pump, its fault overwhelming majority occurred that is in operation is caused by guide bearing.Need the radial force of the rotatable parts of bearing pump due to guide bearing in the work environment, there is the effect of stable pump shaft and wheel rotation.Further for horizontal pump, guide bearing also needs the deadweight of the rotatable parts of bearing pump.When guide bearing wearing and tearing are excessive or damage, the unit axis throw of whole pump can be caused to increase, vibration aggravation, the accident of blade collision housing even occurs.
In current prior art, guide bearing mainly adopts rubber, or graphite, or Babbitt, or the material such as match dragon is made, but is not well positioned to meet industrial needs.Reason is as follows: although 1, rubber guide bearing shock-absorbing performance is good, decay resistance is poor, and a lot of media environment is all inapplicable, such as grease, high temperature, acidity, alkalescence etc.; And rubber guide bearing is shorter for working life, maintenance cost is higher.2, the self lubricity of graphite guide bearing is good, high temperature resistant, decay resistance is good, the media environment that can tolerate is also relatively more extensive, but the shock resistance of graphite guide bearing is poor, and reliability is not high, larger radial force can not be born, easily cracked, and cracked after some component wear that will cause in pump of graphite impurities, even stuck.
Model utility content
The purpose of this utility model is to provide a kind of inserted guide bearing device, not only has self-lubricating property good, high temperature resistant, corrosion-resistant, to be applicable to medium environment advantage, can improve shock resistance again, strengthens reliability, increase the service life, reduce maintenance load, reduce maintenance cost.
For achieving the above object, the technical solution of the utility model is to provide a kind of inserted guide bearing device, and it is arranged on the endoporus of the diffuser of horizontal type multi-stage pump by interference fit, comprise: guide bearing, in the form of a ring, adopts carbon graphite material to make; Steel Support, in the form of a ring, its external diameter is greater than the internal diameter of diffuser, and internal diameter is less than the external diameter of guide bearing; Described guide bearing is arranged on the endoporus of Steel Support by interference fit.
Described Steel Support adopts stainless steel material to make.
Described guide bearing is arranged on the endoporus of Steel Support by high temperature mosaic technology interference fit.
Described inserted guide bearing device is arranged in the endoporus of diffuser by low temperature mosaic technology interference fit.
Described Steel Support is fixedly mounted in the endoporus of diffuser by junction of the edges of two sheets of paper screw.
In sum, inserted guide bearing device provided by the utility model, effectively can solve the use narrow limitation of guide bearing in prior art, guide bearing can be used in the media environment of grease, high temperature, acidity, alkalescence, there is again stronger operational reliability.The utility model can inheriting tradition carbon graphite guide bearing self-lubricating property good, high temperature resistant, corrosion resistant advantage, improves the shock resistance of guide bearing by Steel Support again, strengthens reliability, increases the service life, and reduces maintenance load, reduces maintenance cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the inserted guide bearing device in the utility model;
Fig. 2 is the scheme of installation of the inserted guide bearing device in the utility model.
Embodiment
Below in conjunction with Fig. 1 ~ Fig. 2, describe a preferred embodiment of the present utility model in detail.
As depicted in figs. 1 and 2, be inserted guide bearing device provided by the utility model, it is arranged on the endoporus of the diffuser 1 of horizontal type multi-stage pump by interference fit, comprise: guide bearing 2, in the form of a ring, adopts carbon graphite material to make; Steel Support 3, in the form of a ring, its external diameter is greater than the internal diameter of diffuser 1, and internal diameter is less than the external diameter of guide bearing 2; The endoporus being arranged on Steel Support 3 inlayed by described guide bearing 2 by interference fit.
Inserted guide bearing device described in the utility model is owing to needing the deadweight of bearing radial force and rotary component; and need be immersed in throughout the year there is pressure under water; therefore described Steel Support 3 is adopted stainless steel material and is made by stainless steel integrated machining; decay resistance better and ensure enough rigidity; thus strengthen the intensity of guide bearing 2, play the effect of protection guide bearing 2.
Described guide bearing 2 is made by lathe machining, adopts high temperature mosaic technology to inlay the endoporus being arranged on Steel Support 3, by interference fit compact siro spinning technology.
Inserted guide bearing device described in the utility model is inlayed by low temperature mosaic technology in the endoporus being arranged on diffuser 1.
As shown in Figure 2, described Steel Support 3 is fixedly mounted in the endoporus of diffuser 1 by junction of the edges of two sheets of paper screw 4, prevents whole inserted guide bearing device in running from coming off from diffuser 1.
Inserted guide bearing device provided by the utility model, its concrete installation method comprises following steps:
Guide bearing 2 is inlayed in the endoporus being arranged on Steel Support 3, and is realized compact siro spinning technology by interference fit by S1, employing high temperature mosaic technology, forms inserted guide bearing device;
Described inserted guide bearing device is inlayed in the endoporus being arranged on diffuser 1, and is realized compact siro spinning technology by interference fit by S2, employing low temperature mosaic technology;
S3, described Steel Support 3 to be fixedly connected with diffuser 1 by junction of the edges of two sheets of paper screw 4, to prevent from coming off.
In described S1, specifically comprise following steps:
S11, employing oven carry out heating operation to Steel Support 3, make the endoporus aperture expanded by heating of Steel Support 3 to the external diameter being greater than guide bearing 2;
Steel Support 3 after S12, taking-up heating, puts into the endoporus of Steel Support 3 by guide bearing 2 level;
S13, placement a period of time reduce after making Steel Support 3 cooling meat, and the internal diameter due to Steel Support 3 is less than the external diameter of guide bearing 2, and it makes guide bearing 2 and Steel Support 3 interference fit compact siro spinning technology after shrinking, and forms inserted guide bearing device.
