Description
Technical field
The utility model relates to bearing part, particularly relates to a kind of bearing structure of horizontal type multi-stage pump.
Background technique
Can pump reliable operation, and core is that can bearing structure safety, reliable operation, and the prerequisite of bearing structure safety, reliable operation depends on the indexs such as bearing load, lubricating condition, bearing temperature rise.Existing horizontal type multi-stage pump bearing part many employings rolling bearing form, generally adopt grease lubrication, bearing part mainly adopts nature to cool, radiating condition is poor, under high-speed condition, causes bearing heating, user will drop into a large amount of manpowers and go to safeguard in daily maintenance, makes troubles to user.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of bearing structure of horizontal type multi-stage pump, and this structure is rational in infrastructure, can improve greasy property and radiating effect, extends the working life of bearing.
The utility model is achieved in that the bearing structure of horizontal type multi-stage pump, comprise bearing support, bearing gland A, axle, O RunddichtringO, axle is provided with bearing and bearing fixing sleeve, it is characterized in that: described bearing support inner chamber is provided with bearing, is provided with lubricant oil bottom exocoel; Inside described bearing support, outer ring has been connected by screw bearing bracket, and outside has been connected by screw bearing cap, and bearing support top is provided with the temperature measuring element A measuring bearing temperature, and bottom is provided with the temperature measuring element B measuring lubricating oil temperature; Small-sized fans is provided with in described bearing bracket; Described bearing fixing sleeve is provided with disc; Bearing gland B has been connected by screw outside described bearing cap.
The head of temperature measuring element A described in the utility model contacts with the bearing of inner chamber.
Bearing support outer ring described in the utility model is provided with radiating fin.
Bearing cap outer side surface described in the utility model is provided with radiating fin.
Bearing bracket described in the utility model is provided with radiating groove.
Oil-return groove is provided with inside bearing gland A described in the utility model and bearing gland B.
The utility model is rational in infrastructure, improve greasy property and radiating effect, significantly extends the working life of bearing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure 1, bearing bracket, 2, bearing support, 3, bearing gland A, 4, axle, 5, bearing, 8, temperature measuring element A, 9, bearing cap, 10, bearing gland B, 11, bearing fixing sleeve, 12, disc, 13, lubricant oil, 14, O RunddichtringO, 15, temperature measuring element B.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
The bearing structure of horizontal type multi-stage pump, comprises bearing support 2, bearing gland A3, axle 4, O RunddichtringO 14, axle is provided with bearing 5 and bearing fixing sleeve 11, it is characterized in that: described bearing support 2 inner chamber is provided with bearing 5, is provided with lubricant oil 13 bottom exocoel; Inside described bearing support 1, outer ring has been connected by screw bearing bracket 7, and outside has been connected by screw bearing cap 9, and bearing support 2 top is provided with the temperature measuring element A8 measuring bearing temperature, and bottom is provided with the temperature measuring element B15 measuring lubricating oil temperature; Small-sized fans is provided with in described bearing bracket 7; Described bearing fixing sleeve 11 is provided with disc 12; Bearing gland B10 has been connected by screw outside described bearing cap 9.The head of described temperature measuring element A8 contacts with the bearing 5 of inner chamber.Described bearing support 2 outer ring is provided with radiating fin.Described bearing cap 9 outer side surface is provided with radiating fin.Described bearing bracket 7 is provided with radiating groove.Oil-return groove is provided with inside described bearing gland A3 and bearing gland B10.During concrete enforcement, bearing adopts thin oil lubricant, carries oil with disc, avoid the drawback that lubricating oil temperature that bath oiling brings is higher, bearing gland B and bearing support are processed with ring radiating fin, increase the heat exchange area of itself and air, improve radiating effect; The small-sized fans being provided with particular design in bearing bracket plays forced heat radiation effect, fan by envelope in bearing bracket, without any security risk.By showing disc lubrication test; after pump startup; lubricant oil can just get rid of to bearing in the 2 s times of ground by disc; in addition bearing gland is provided with spill port; enclose under making to shut down rear bearing at every turn and all store certain lubricant oil; for startup next time when disc does not also put forward oily prerequisite in time for pre-lubrication, ensure that bearing has sufficient oil lubrication in all operating.Horizontal type multi-stage pump is as follows through 6 hours stable operation rear bearing temperature: drive end bearing temperature 56.9 ° of C, and lubricating oil temperature is 44 ° of C, and non-driven-end bearing temperature is 61.7 ° of C, and lubricating oil temperature is 42.3 ° of C; When ambient temperature is 27 ° of C, after non-driven-end bearing runs 6 hours, temperature is no more than 62 ° of C, and bearing temperature rise is 35 ° of C, meets API610 standard-required.Carried out bearing life calculating to bearing part, bearing life is greater than 100000 hours.
