Abstract
The utility model relates to a guiding vane and volute casing combination type multi-stage miniature pump, which is a miniature multi-stage pump. The utility model is a three stage miniature water pump formed by the combination of a guiding vane-shaped structure and a volute casing-shaped structure, and three-stage pump chambers are composed of flow guide casings and volute casings. The connection position of the pump chambers is provided with a seal device, the upper parts of the flow guide casing and the volute casing are respectively provided with an exhaustion hole, and the upper part of a third stage pump chamber is provided with a water filling hole. The utility model has the characteristics of reasonable design, small size, light weight, long service life, energy saving, shortened time of operation and work and high efficiency. The lift head of the utility model is as high as more than 40 meters.
Description
The utility model relates to a kind of miniature multistage pump---stator volute combined multi-stage micropump.
At present, the pump class of domestic common employing has the pump of voluted type centrifugal pump and miniature stator formula structure.The voluted type multistage centrifugal pump is generally the worker, there is the excessive shortcoming of axial dimension in agricultural with large pump, and the voluted type micro centrifugal pump has only single-stage pump, does not have multistage; The pump class of miniature stator formula structure, its structure are that impeller passes to subordinate impeller with the liquid suction by stator by centrifugal force, and the shortcoming of this structure is that efficient is low.
The purpose of this utility model is to provide a kind of have high-lift, high efficiency, multistage micro centrifugal pump---stator volute combined multi-stage micropump for worker, agricultural production and tall building.
The utility model stator volute combined multi-stage micropump content Description:
The utility model stator volute combined multi-stage micropump is characterized in that: be with stator formula structure and voluted type textural association three grades of micro pumps together; Constitute the triplex chamber by blower inlet casing and volute, the front end of blower inlet casing is connected with water inlet tap, forms first order pump chamber, and the rearward end of blower inlet casing and the front end of volute are connected to form second level pump chamber, and the rearward end of volute and frame linking front portion connect and compose third level pump chamber; Joint at pump chamber is provided with seal arrangement, and the cylindrical place of impeller respectively is provided with a stator in first order pump chamber and second level pump chamber; Respectively be provided with an exhaust port above blower inlet casing and volute, be provided with a water injection hole above third level pump chamber, exhaust port and water injection hole seal by bolt; Three impellers pass motor shaft, and the centre respectively is provided with a sealing corrosion rubber cushion.
That the utility model stator volute combined multi-stage micropump has is reasonable in design, compact structure, manufacturing process is simple, easy to maintenance, the life-span is long, volume is little, lightweight characteristics, its lift height, can reach more than 40 meters, the efficient height of water pump, but energy saving shortens the operation operating time, is applicable to the field, farmland discharging-irrigating, mine water and tall building water.
Embodiment:
