Abstract
The utility model discloses a novel stainless steel centrifugal pump which comprises a base plate, a pump body and impeller assemblies. The pump body is installed inside a rack. The upper end and the lower end of the pump body are connected with a motor and the base plate respectively. An aluminum outer shell is arranged outside the motor. An outer sleeve is arranged on the periphery of the pump body. A shaft is arranged in the center of an inner cavity of the outer sleeve, and the impeller assemblies are evenly installed around the periphery of the shaft from top to bottom. Meanwhile, a middle cavity body is formed at the top end of the inner cavity the outer sleeve, and a wear-resisting mechanical sealing element is installed inside the middle cavity. The novel stainless steel centrifugal pump has the advantages that structural assemblies are simplified, sealing performance is improved, maintenance cost is saved, a runner is smooth, the service life is prolonged and secondary pollution is avoided due to the fact that bearing bushes and a shaft sleeve are made of hard alloy, and leakage is avoided due to the wear-resisting mechanical sealing element. The novel stainless steel centrifugal pump has the advantages of being small in size, light in weight, low in noise, stable in operation, convenient to install and convey, wide in applied range, energy-saving, environment-friendly and the like.
Description
Technical field
The utility model relates to a kind of centrifugal pump, relates in particular to a kind of novel stainless steel centrifugal pump.
Background technique
Stainless steel centrifugal pump is to be widely used in building living water, fire fighting water system, and a kind of universal fluid machinery of chemical engineering industry system has vertical, horizontal, single-stage, multistage, single suction, double suction, various ways such as self-priming.Plurality of advantages such as it has that performance wide accommodation (comprise flow, pressure head and to the adaptability of fed sheet of a media character), volume are little, simple in structure, processing ease, operating cost are low.At present, the Flow-rate adjustment mode of centrifugal pump mainly contain modulating valve control, speed Control and pump also, series connection regulates etc., because the principle difference of various regulative modes, except the pluses and minuses that oneself is arranged, the energy loss that causes is also different, in order to seek the best, energy consumption minimum, the most energy-conservation Flow-rate adjustment mode, must understand the Flow-rate adjustment mode of centrifugal pump and the relation between the energy consumption all sidedly.But because parts-moulding unreasonable structure such as existing a lot of product internal impeller, pump case, axle sleeve have shortened working life and easily caused secondary pollution, machine volume is bigger than normal and weight is big, is not easy to install and transportation; Simultaneously, also be embodied in place mat, sealing and connection part between these main body parts, these all impel safeguards inconvenience, influences operational efficiency to a great extent.Therefore, at above aspect, need reasonably improve prior art.
Summary of the invention
At above defective, the utility model provides that a kind of volume is little and in light weight, low noise and running steadily, the assembly that simplifies the structure, improved sealability, saved maintenance cost, be convenient to install and transportation, novel stainless steel centrifugal pump that application area is wider, to solve many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
A kind of novel stainless steel centrifugal pump, comprise base plate, the pump housing, impeller assembly, the pump housing is installed on frame inside and pump housing upper/lower terminal connects motor, base plate respectively, described motor outside is provided with the layer of aluminum shell, described pump housing periphery arranges outer sleeve, is positioned at outer sleeve lumen centers position and axle is set and around this periphery some impeller assemblies is installed evenly from top to bottom; Simultaneously, described outer sleeve inner chamber top arranges middle chamber and wearable mechanical seal spare is equipped with in this middle chamber inside.
Correspondingly, be positioned at the outer sleeve top coupling guard is set, every impeller assembly inside edge is installed a neck ring respectively.
The beneficial effect of novel stainless steel centrifugal pump described in the utility model is: by reasonable setting by the stamping forming water pump internal impeller of stainless steel, pump case and all the other main body parts and cooperate the outer shell motor of aluminium, the simplified structure assembly, improved sealability, saved maintenance cost, can make runner smooth, bearing shell, axle sleeve adopt cemented carbide, are conducive to increase the service life and avoid secondary pollution; Adopt wearable mechanical seal spare, do not have and leak, complete machine has that volume is little and in light weight, low noise and running steadily, be convenient to advantages such as installation and transportation, application area are wide, energy-conserving and environment-protective.
Description of drawings
