Abstract
The utility model provides an improved shaft tubular pump, which has the advantages that the installation is time-saving and labor-saving, the overhaul cost is low, and the civil engineering cost is reduced. The shaft tubular pump comprises a pump well and a shaft; a motor, a gearbox and a water pump thrust bearing are positioned in the shaft; a water pump runner is positioned in the pump well; the motor is connected with the input shaft of the gearbox; and the output shaft of the gearbox is connected with the water pump thrust bearing which is connected with the water pump runner through a pump shaft. The shaft tubular pump is characterized in that the pump shaft is supported on a demountable isolating mechanism which is mounted in a middle position between the pump well and the shaft.
Description
(1) technical field
The utility model relates to the plumbing equipment field, is specially a kind of modified model silo infusion pump.
(2) background technique
Existing silo infusion pump, see Fig. 1, Fig. 2, it comprises pump sump 8, vertical shaft 1, partition wall 6, described pump sump 8 is positioned at described partition wall 6 one sides, described vertical shaft 1 is positioned at described partition wall 6 opposite sides, motor 2, gear-box 3, water pump thrust-bearing 4 is positioned at described vertical shaft inside, water pump runner 7 is positioned at described pump sump 8 inside, described motor 2 connects the input shaft of described gear-box 3, the output shaft of described gear-box 3 connects described water pump thrust-bearing 4, described water pump thrust-bearing 4 connects described water pump runner 7 by pump shaft 5, described pump shaft 5 passes the preformed hole 9 of described partition wall 6 inside, the intermediate portion of described pump shaft 5 is supported on described partition wall 6, in the said structure, owing to have concrete partition 6 between pump sump 8 and the vertical shaft 1, when water pump is installed, pump shaft 5 must be hung down from vertical shaft 1 side, pass the preformed hole 9 in the partition wall 6 again, water pump thrust-bearing 4 is installed then, gear-box 3 and motor 2, water pump runner 7 must carry out in pump sump 8 with being connected of pump shaft 5, and the operating space is little, in sum, the installation of its water pump is wasted time and energy, and when needing to overhaul afterwards, its cost of overhaul height; In addition, because pump shaft 5 need be from 1 li lifting of vertical shaft, the length of vertical shaft 1 must also increase the civil engineering cost of vertical shaft 1 greater than the length of pump shaft 5.
(3) summary of the invention
At the problems referred to above, the utility model provides a kind of modified model silo infusion pump, and it is time saving and energy saving when installing, and the cost of overhaul is low, and civil engineering cost is reduced.
Its technological scheme is such: it comprises pump sump, vertical shaft, motor, gear-box, water pump thrust-bearing are positioned at described vertical shaft inside, the water pump runner is positioned at described pump sump inside, described motor connects the input shaft of described gear-box, the output shaft of described gear-box connects described water pump thrust-bearing, described water pump thrust-bearing connects described water pump runner by pump shaft, it is characterized in that: described pump shaft is supported on a dismountable interrupter, and described interrupter is installed on the neutral position of described pump sump, described vertical shaft.
It is further characterized in that: described interrupter comprises upper mechanism, lower mechanisms, described upper mechanism, lower mechanisms symmetry, the fastening neutral position that is installed on described pump sump, described vertical shaft of described lower mechanisms, described pump shaft intermediate portion is supported on described lower mechanisms, described upper mechanism is loaded on described lower mechanisms top, described pump shaft intermediate portion is loaded in the formed cavity of interrupter that described upper mechanism, lower mechanisms assembly, and described interrupter integral body is Y shape.
In the said structure of the present utility model, because described pump shaft is supported on a dismountable interrupter, described interrupter is installed on described pump sump, the neutral position of described vertical shaft, when water pump is installed, the runner of water pump can carry out on pump house ground with being connected of pump shaft, need in narrow and small pump sump, not carry out being connected of pump shaft and runner, water pump can connect whole rotatable parts back integral body and straight up and down lift on pump house ground when installing, easy for installation, time saving and energy saving, during its maintenance, the whole rotatable parts of water pump can integral body straight up and down lift, and do not need the thrust bearing part that will be in the vertical shaft, gear-box and motor are removed, its cost of overhaul is low, and pump shaft need not to lift in vertical shaft, thereby the length of vertical shaft can shorten, and its civil engineering cost is reduced.
