Abstract
The utility model discloses a fully-sealed centrifugal water pump, which comprises a pump cover, a pump body, a connecting seat, a bearing block, a bearing, a driving shaft, a driving device, an impeller and a water seal and is characterized in that the connecting seat and the bearing block are fixedly connected into an integral structure and the pump body is connected with the end surface of the connecting seat by a fastener. As further improvement of the utility model, the pump cover, the pump body, the connecting seat, the bearing block and the impeller are all made of aluminum alloy material; and the connecting seat and the bearing block are fixedly connected into a whole body by accurate die casting. The utility model can prevent environment liquid from permeating into the pump body and lubricant grease from losing and has the advantages of long service life, low cost and stable performance.
Description
Technical field
The utility model relates to a kind of centrifugal suction pump.
Background technique
Centrifugal water pump is to utilize atmospheric effect, water is promoted to the hydraulic machinery of eminence from lower.It is made up of water pump, dynamic power machine and transmission device.It is widely used in feedwater, the draining in field irrigation, draining and industrial and mining enterprise and cities and towns.
Be extensive use of your suction pump at present, comprise pump cover, the pump housing, connecting base, transition connecting base, bearing support, bearing, transmission shaft, transmission device, impeller, water seal, wherein pump cover, the pump housing, connecting base, transition connecting base, bearing support connect successively by fastening piece, because the existence of transition connecting base and connecting base profile installation dimension need, parts such as bearing and transmission device can't be in whole sealing status, the bearing lubrication grease can run off rapidly, causes environmental pollution and bearing inordinate wear and temperature rise to cross high defective; Environmental liquids can be infiltrated in the pump housing simultaneously, causes bearing and transmission device corrosion, shortens the working life of water pump; And impeller, connecting base, the pump housing, pump cover, transition connecting base and bearing support make and cylinder iron are to utilize precision to melt molded work by raw material, and the fabricating cost height can't be produced in enormous quantities; Adopting cast iron is that main raw material(s) causes water pump component weight bigger, increases the motor power consumption; The distortion of melting mould foundry is bigger, causes pump cover inner edge and impeller foreign aid bonding gap to have than big-difference, and key performances such as the water pump water yield and lift have unstability.
The model utility content
The purpose of this utility model is the above-mentioned deficiency at prior art, and a kind of hermetically sealed centrifugal suction pump is provided, and it can prevent that environmental liquids from can infiltrate the loss of the pump housing and lubricant grease, has that long service life, cost are low, the advantage of stable performance.
For achieving the above object, hermetically sealed centrifugal suction pump of the present utility model, comprise pump cover, the pump housing, connecting base, bearing support, bearing, transmission shaft, transmission device, impeller, water seal, it is characterized in that connecting base and bearing support are the overall structure that is fixed with one, the pump housing connects by fastening piece with the end face of connecting base.
The utility model has been cancelled the transition connecting base, with connecting base and bearing support for being fixed with one, the pump housing connects by fastening piece with the end face of connecting base, bearing, transmission shaft, transmission device are in whole sealing status in the pump housing and connecting base, can prevent effectively that environmental liquids from can infiltrate the loss of the pump housing and lubricant grease, avoid component by corrosion, prolonged working life;
As further improvement of the utility model, described pump cover, the pump housing, connecting base, bearing support, impeller are aluminum alloy material, and connecting base and bearing support are fixed with one by accurate die casting; The weight of aluminum alloy is lighter, adds the efficient height of accurate die casting forming device, the little characteristics of distortion, can reduce cost and the motor power consumption, and guarantee the conformity of impeller and pump cover end clearance, thereby guarantee the stable of pump performance.
In sum, the utility model can prevent that environmental liquids from can infiltrate the loss of the pump housing and lubricant grease, has that long service life, cost are low, the advantage of stable performance.
Description of drawings
Fig. 1 is the utility model embodiment's a plan view.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
By shown in Figure 1, this hermetically sealed centrifugal suction pump, the transmission device, impeller 8, the water seal 9 that comprise pump cover 1, the pump housing 2, connecting base 3, bearing support 3a, bearing 4, transmission shaft 5, constitute by gear shaft 6 and planetary pinion 7, described pump cover 1, the pump housing 2, connecting base 3, bearing support 3a, impeller 8 are aluminum alloy material, and connecting base 3 and bearing support 3a are fixed with one by accurate die casting; The pump housing 2 connects by bolt 10 with the end face of connecting base 3.
The utility model has been cancelled original transition connecting base, with connecting base 3 and bearing support 3a for being fixed with one, the pump housing 2 connects by bolt 10 with the end face of connecting base 3, bearing 4, transmission shaft 5, gear shaft 6 and planetary pinion 7 are in whole sealing status in the pump housing 2 and connecting base 3, can prevent effectively that environmental liquids from can infiltrate the loss of the pump housing and lubricant grease, avoid component by corrosion, prolonged working life; Described pump cover 1, the pump housing 2, connecting base 3, bearing support 3a, impeller 8 are aluminum alloy material, its weight is lighter, add the efficient height of accurate die casting forming device, the little characteristics of distortion, can reduce cost and the motor power consumption, and the conformity of assurance impeller 8 and pump cover 1 end clearance, thereby guarantee the stable of pump performance.
