Abstract
The utility model relates to the technical field of pump structures, particularly to a compact structured self-priming sewage pump, which comprises a suspension frame, a pump cover and a rear guard plate that are all arranged in a pump casing; and a cooling system is arranged on the suspension frame. A pump shaft passes through the pump casing and passes out of the suspension frame, an impeller positioned inside the pump casing is arranged on the pump shaft, a front guard plate connected on the pump casing is arranged at the front end of the impeller, a the rear guard plate and the pump cover connected on the suspension frame are sequentially arranged between the rear end of the impeller and the suspension frame, and the rear guard plate is connected on the pump cover; and the inlet components of the pump sequentially include an inlet short tube, a short tube press plate and an inlet elbow tube, and the inlet elbow tube is connected with the pump casing. The self-priming sewage pump provided by the utility model has compact structure, small floor area, good self-priming performance and no blockage, is convenient to install, and can meet the transfer requirements of different media.
Description
Technical field
The utility model relates to the pump structure technical field, is mainly used in transportation concentration≤10%, and length of staple is in the technical field of 10mm-100mm liquid medium transfer pump.
Background technique
When being used for liquid mediums such as municipal drainage project, river embankment breed, light industry, papermaking, weaving, food, chemical industry, electric industry, fiber, slurry processing and carrying; Existing self-priming pollution discharge pump structure is generally the suspension external; And suspension does not have cooling system; Therefore existing self-priming pollution discharge pump generally has following shortcoming: 1) suspension is arranged on the outside, and its form structure is bigger, and floor space is big, arrangement is inconvenient; 2) because structure is bigger, its sealability is difficult to guarantee that leakage rate is big, efficient is low that the self-priming height is also low; 3) suspension does not have cooling system, so the life-span of pump shaft and bearing is short, causes the whole rotary system of pump and all fragile with this system's counterpart.
The model utility content
The utility model is to above-mentioned defective, and purpose is to provide a kind of easy for installation, good seal performance, good, the no plugging performance of self-priming performance is good, efficient is high, the life-span is long, can satisfy the efficient nothing obstruction self-priming pollution discharge pump of various medium transport requirements.
The technological scheme of the utility model is: suspension, pump cover and rear wing all are arranged on pump case inside; Pump shaft passes pump case; And from suspension, pass; Establish the impeller that is in the pump case on the pump shaft, the front end of impeller is established the front fender that is connected on the pump case, establishes rear wing between impeller rear end and the suspension successively and is connected the pump cover on the suspension; Rear wing is connected on the pump cover, the liquid entering hole that the level of offering is offered on the pump case and with the vertically disposed liquid outlet of liquid entering hole.
Built-in suspension can improve sealing and self-priming performance.
Suspension is provided with cooling chamber, can give the cooling of bearing and pump shaft timely.
The utility model has the advantages that: 1) the utility model suspension design is inner at pump case, makes compact structure, floor space little, and to reach transportation, easy for installation and raising sealability and self-priming performance, its self-priming height can reach 9 meters; 2) the utility model suspension is provided with cooling system, can give the cooling of bearing and pump shaft timely, improves its life-span, and in the life-span of the whole rotary system that indirect raising cooperates with pump shaft, bearing, it is long to prolong this pump life-span.
Description of drawings
Fig. 1 is the structural representation of the utility model
1 is that front fender, 2 is that pump case, 3 is that impeller, 4 is that rear wing, 5 is that pump cover, 6 is that suspension, 7 is that bearing cap, 8 is that pump shaft, 9 is a cooling chamber among the figure.
Embodiment
The suspension 6 of the utility model, pump cover 5 and rear wing 4 all are arranged on pump case 2 inside, its good seal performance, and self-priming performance is good.Pump shaft 8 passes pump case 2 and from suspension 6, passes; Establish the impeller 3 that is in the pump case 2 on the pump shaft 8; The front end of impeller 3 is provided with the front fender 1 that is connected on the pump case 2; Establish rear wing 4 between impeller 3 rear ends and the suspension 6 successively and be connected the pump cover 5 on the suspension 6, rear wing 4 is connected on the pump cover 5, the liquid entering hole that the level of offering is offered on the pump case 2 and with the vertically disposed liquid outlet of liquid entering hole; The utility model suspension 6 is provided with cooling chamber 9, can dispel the heat to suspension 6, in time drains suspension 6 internal heat, improves the life-span of bearing, thereby improves the stability of the whole system that cooperates with bearing, the life-span of improving pump.
The connection set structure of the utility model can be: suspension 6, pump cover 5 and rear wing 4 all design in pump case 2 inside, make its compact structure, good seal performance; On suspension 6, be provided with cooling chamber 9, can reduce the temperature in suspension 6 chambeies, improve bearing life.
The working procedure of the utility model is: the utility model only needs pump shaft 8 centers of pump and rotor center just to align and can fix when installing, and 9 needs of cooling chamber connect cooling water from cooling vent and just can cool off suspension.
Claims (2)
1. compact structure self-priming pollution discharge pump is characterized in that, comprises being arranged on the inner suspension of pump case; Pump shaft passes pump case and from suspension, passes; Establish the impeller that is in the pump case on the pump shaft; The front end of impeller is established the front fender that is connected on the pump case; Establish successively between impeller rear end and the suspension rear wing be connected the pump cover on the suspension, rear wing is connected on the pump cover, the liquid entering hole that the level of offering is offered on the pump case and with the vertically disposed liquid outlet of liquid entering hole.
2. compact structure self-priming pollution discharge pump according to claim 1 is characterized in that said suspension is provided with cooling chamber.
