Abstract
The utility model relates to a horizontal-type constant-pressure tangent fire-fighting pump which comprises a cast-iron pump cover, a pump body and an impeller assembly. The lateral side of the pump body is horizontally connected with an installed motor. A main shaft is horizontally arranged at the position of the center inside the pump body. A water-stopping ring is arranged at the outer end of the main shaft in a sleeved mode. A mechanical sealing element is arranged at the section, located on the inner side of the cast-iron pump, in the middle of the main shaft. The impeller assembly is installed at the inner end of the main shaft. An O-shaped sealing ring is arranged in a sleeved mode at the portion, located on the periphery of the impeller assembly, of the outer wall face of the pump body. The horizontal-type constant-pressure tangent fire-fighting pump has the advantages that a shaft coupler is eliminated, reliability of a pump assembly can be improved, connection of a pipeline is simplified, operational stability is strengthened, service life is prolonged, noise is small, corrosion-resisting performance is good, and the horizontal-type constant-pressure tangent fire-fighting pump can be applicable to water feeding for a fixed fire-fighting system of an industrial building or a civil building, a water-feeding system shared by fire fighting and living, and other occasions such as water feeding for a building, a municipal administration, a mine and a boiler.
Description
Technical field
The utility model relates to a kind of fire water pump, relates in particular to a kind of horizontal constant voltage tangent line fire water pump.
Background technique
Fire water pump mainly is installed on fire-fighting truck, fixed fire extinguishing system or other fire fighting device, and the pump fire-fighting usefulness as liquid extinguishers such as transporting water or Foam solutions can be divided into different kinds according to different mode classifications., nothing hermetically sealed with it leaked, corrosion resistant characteristics, and the departments such as environmental protection, water treatment, fire-fighting that can be widely used in are used for pumping each class I liquid I, are to create the ideal pump that does not have leakage, pollution-free civilized workshop, civilized factory.But, superpressure when existing similar mill run often appears at small flow in the fire-fighting scene and when big flow, run out of the phenomenon of water, reliability for horizontal pump unit is relatively poor, especially has coupler structure, relevant partially sealed occurs phenomenon such as corrosion, influence operation and durability degree easily.In addition, a lot of defectives also are embodied in place mat, sealing and the connection part between the main body parts such as the pump housing, impeller, and these all impel safeguards inconvenience, influences operational efficiency to a great extent.
Summary of the invention
At above defective, the horizontal constant voltage tangent line fire water pump that the utility model provides a kind of reliability of having cancelled coupling, the assembly that simplifies the structure, can having improved pump assembly, be conducive to strengthen operation stability and working life, noise is less, corrosion resistance is preferable is to solve many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
A kind of horizontal constant voltage tangent line fire water pump, comprise cast iron pump cover, the pump housing, impeller assembly, the cast iron pump cover is installed between the pump housing and motor, described pump housing side joins with installation motor level, pump housing inside center position is horizontally disposed with a main shaft and this outer end and machine shaft and joins, main shaft outer end wherein is with a water retaining ring, and the main shaft intermediate section that is positioned at cast iron pump cover inboard arranges a mechanical sealing element; Impeller assembly is installed in the inner end of described main shaft, simultaneously, is positioned on the pump housing outer wall of impeller assembly periphery and is with an O-ring seals; Outerface of spindle fitting key.
The beneficial effect of horizontal constant voltage tangent line fire water pump described in the utility model is: cancelled coupling, can improve the reliability of pump assembly; By the position annexation of cast iron pump case, impeller assembly and three main body parts of the pump housing rationally is set, simplified the connection of pipeline, cooperative mechanical sealing simultaneously, water retaining ring, the assembly that simplifies the structure has the simplified structure assembly, is conducive to strengthen operation stability and working life, advantage such as noise is less, corrosion resistance is preferable; Applicable to industry, the fixedly feedwater of fire-fighting system of civil building, various occasions such as the water supply system that fire-fighting and life share and building, municipal administration, industrial and mineral, boiler feed water.
