Abstract
The utility model relates to a middle section of a non-cover-plate guide blade of a vertical multistage pump capable of discharging accumulated gas inside the pump, comprising a middle section of a non-cover-plate guide blade of a vertical multistage pump. The middle section of the non-cover-plate guide blade of the vertical multistage pump capable of discharging accumulated gas inside the pump is characterized in that a hollow cavity inside the middle section is provided with 2-3 through holes; and the diameter of the through holes is 6mm. The middle section of the non-cover-plate guide blade of the vertical multistage pump capable of discharging accumulated gas inside the pump has the advantages of discharging accumulated gas inside the pump during use, guaranteeing the stability of flow rate and temperature rise of a pump body, reducing the shock of the pump body and guaranteeing the water pump safety and high efficiency.
Description
Technical field
The utility model relates to the segment structure that is used for not having the cover plate stator, a kind of especially stage casing of the MODEL VERTICAL MULTISTAGE PUMP that pneumatosis in the pump is discharged can not being had the cover plate stator.
Background technique
Present most of MODEL VERTICAL MULTISTAGE PUMP is when installing no cover plate stator, employed stage casing is for weight reduction, the common position reduced thickness that all stage casing is cooperated with the stator blade, but in the stage casing, formed the cavity of a sealing, the gas that the cavity inner product is deposited when pump is poured water or use can't be discharged, cause pneumatosis in the pump, less than normal, the problems such as pump housing intensification is too fast, pump housing vibrations of flow of pump in use can occur.Influence water pump safety and use efficiently.
Summary of the invention
The purpose of this utility model is to solve existing MODEL VERTICAL MULTISTAGE PUMP when no cover plate stator is installed, the pneumatosis problem that the cavity that cause because of loss of weight on top, stage casing produces when reality is used, make the gas of pump complete excavationg pump inner accumulated of energy when pouring water and use, processing simply and not can make the medium in the stage casing that the medium in higher level's stator is impacted, thereby the efficient that has guaranteed pump is unaffected.A kind of stage casing of the MODEL VERTICAL MULTISTAGE PUMP that pneumatosis in the pump is discharged can not being had the cover plate stator of the utility model design comprises that MODEL VERTICAL MULTISTAGE PUMP do not have the stage casing of cover plate stator, it is characterized in that: offer vent on the cavity in the stage casing.It is characterized in that: the number of vent is 2 to 3.It is characterized in that: the diameter of vent is 6 millimeters.The utility model has the advantages that and pneumatosis in the pump in use can be discharged, guarantee the flow of pump and stablizing of pump housing intensification, reduce the vibrations of the pump housing, guarantee water pump safety and use efficiently.
Description of drawings
Accompanying drawing 1 is the middle segment structure of MODEL VERTICAL MULTISTAGE PUMP when no cover plate stator is installed of prior art, and A is the interior pneumatosis position of pump,
Accompanying drawing 2 is a structural representation of the present utility model, and 1 is the MODEL VERTICAL MULTISTAGE PUMP stage casing, and 2 is the vent on the cavity,
Embodiment
Comprise among the figure that MODEL VERTICAL MULTISTAGE PUMP do not have the stage casing of cover plate stator, it is characterized in that: offer vent on the cavity in the stage casing.It is characterized in that: the number of vent is 2 to 3.It is characterized in that: the diameter of vent is 6 millimeters.As shown in the figure: the easy accumulated gas of cavity of intersegmental part in before not improving, improve the back shown in accompanying drawing two: the aperture of making a call to a φ 6 at cavity top along continuous straight runs, if can adding more greatly, the actual volume of stage casing cavity bores 2-3 aperture, when operation, pneumatosis in the pump in use can be discharged, guarantee the flow of pump and stablizing of pump housing intensification, reduce the vibrations of the pump housing, guarantee water pump safety and use efficiently.
Claims (3)
