Abstract
The utility model relates to a vertical type constant pressure tangent fire pump which comprises a cast-iron pump cover, a pump body and an impeller assembly. A main shaft is vertically arranged in the center inside the pump body, and the outer end of the main shaft is connected with a rotating shaft of a motor. The motor is vertically mounted above the pump body. The cast-iron pump cover is mounted on the top of the pump body and connected with the pump body through a flange plate. Two sides of the pump body are respectively provided with a hemispheric cavity which protrudes outwards. The vertical type constant pressure tangent fire pump has the advantages that pipe connection is simplified, meanwhile the fire pump is matched with a mechanical seal and a water blocking ring, and a structural component is simplified; and the fire pump has the advantages of simplifying the structural component, and being capable of improving reliability of a pump unit, beneficial to strengthening operational stability and prolong service life, small in noise, good in corrosion resistance, and capable of being suitable for water supplying of fixed fire extinguishing systems of industrial and civil architectures, water supply systems shared by fire protection and living, water supplying of buildings, municipal administration, mining industry, boilers, and other occasions.
Description
Technical field
The utility model relates to a kind of fire water pump, relates in particular to a kind of vertical 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 no choma prevents stuck 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 the vertical pump unit below the 75kW is relatively poor, and partially sealed occurs phenomenon such as corrosion easily, influence operation and durability degree.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 vertical constant voltage tangent line fire water pump that the utility model provides a kind of assembly that simplifies the structure, can improve the reliability of 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 vertical constant voltage tangent line fire water pump, comprise cast iron pump cover, the pump housing, impeller assembly, pump housing inside center vertically arranges a main shaft and this outer end and machine shaft and joins, the vertical motor of installing in described pump housing top is positioned at pump housing top installation cast iron pump cover and this cast iron pump cover and is connected by flange plate with the pump housing; Be positioned at the pump housing both sides hemisphere chamber that outwards protrudes is set respectively; The inner end of described main shaft is installed impeller assembly and is locked described outerface of spindle fitting key by impeller nut.
Be positioned at the main shaft outer end and be with a water retaining ring, the main shaft intermediate section that is positioned at cast iron pump cover inboard arranges a mechanical sealing element.
The beneficial effect of vertical constant voltage tangent line fire water pump described in the utility model is: 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, have the assembly that simplifies the structure, can improve pump assembly reliability, be 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.
