Technical field
This utility model relates to a kind of for the device to centrifugal pump of horizontal axis automatic water-supply, belongs to centrifugal pumping apparatus technical field.
Background technology
General supply and drain water system equipment mainly by upper hose, be arranged on several parts such as the bottom valve of upper hose end, water pump, motor and hydraulic pipeline and form.The supply and drain water system adopting centrifugal pump of horizontal axis is both needed to fill water in the pump housing before centrifugal pump starts, with the air in blowdown pump body, it is ensured that centrifugal pump can normal operation after starting.And the bottom valve being arranged on upper hose end to be a kind of water rear defence sealing of filling in the pump housing blow back into the critical piece of tank, bottom valve can so that water pump can rely on water pump suction easily to open after normal startup.But bottom valve is also the parts that a kind of fault rate is high, especially in the system high at lift, the discharge water yield is big, according to actually used statistics, almost each monthly there will be 45 faults, all can directly result in centrifugal pump water pump after breaking down cannot again normally start, it is necessary to maintenance or replacing every time.Therefore the fault rate being under not how eliminating bottom valve is problem demanding prompt solution.
Utility model content
Problem to be solved in the utility model is to provide a kind of centrifugal pump of horizontal axis automatic water supply device, this automatic water supply device is without installing bottom valve parts additional at upper hose, can start by without bottom valve when can realize water pump operation, it is to avoid the interference that bottom valve fault is properly functioning to water system.
The technical scheme solving above-mentioned technical problem is:
A kind of centrifugal pump of horizontal axis automatic water supply device, it includes centrifugal pump, vacuum storage tank, flow pipe, centrifugal pump suction hose, the two ends of flow pipe are connected with vacuum storage tank top and tank respectively, one end of centrifugal pump suction hose is connected to the side of vacuum storage tank bottom, and the other end is connected with centrifugal pump water sucking mouth.
Above-mentioned centrifugal pump of horizontal axis automatic water supply device, described vacuum storage tank installation site and centrifugal pump installation site are in same level, and the centrifugal pump vertical dimension from the tank water surface is less than centrifugal pump self water absorbing properties maximum vertical height.
Above-mentioned centrifugal pump of horizontal axis automatic water supply device, the diameter of described flow pipe is more than or equal to centrifugal pump suction hose diameter.
The beneficial effects of the utility model are:
This utility model centrifugal pump suction hose is directly connected with vacuum storage tank, by vacuum storage tank constantly to centrifugal pump automatic water-supply, it is no longer necessary to be additionally arranged at the bottom bottom valve at centrifugal pump suction hose, centrifugal pump no longer because of bottom valve frequently occurs fault and cannot normal operation.This utility model simple in construction, easy to use, safeguard simple and fast, use economical reliable, and apply respond well, achieve without bottom valve when centrifugal pump runs to start, it is to avoid the disadvantage that the centrifugal pump water pump that bottom valve causes after breaking down cannot normally start again, can promote the use of.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, labelling is as follows: vacuum storage tank 1, centrifugal pump 2, manually add water valve 3, flow pipe 4, centrifugal pump suction hose 5, the artificial filler 6 of water tank, centrifugal pump outlet pipe 7, tank 8, the tank water surface 9.
Detailed description of the invention
This utility model is made up of vacuum storage tank 1, centrifugal pump 2, manually add water valve 3, flow pipe 4, centrifugal pump suction hose 5, the artificial filler 6 of water tank.
Showing in figure, vacuum storage tank 1, for sealing container, is welded by common iron plate, it is desirable to seal is good, water-tight, gas leakage, and minimum should be centrifugal pump suction hose 5 volume 46 times of its volume can suitably strengthen.
Figure shows, manually adds water valve 3 and artificial filler 6 is arranged on the upper end of vacuum storage tank 1, for adding water to vacuum storage tank 1.When vacuum state is not good in vacuum storage tank 1, opens the valve 3 that manually adds water and added water in vacuum storage tank 1 by the artificial filler 6 of water tank, after water is filled it up with, close the valve 3 that manually adds water, keep the seal of vacuum storage tank 1.
Showing in figure, one end of flow pipe 4 is connected to the top of vacuum storage tank 1, and the other end is inserted into the tank water surface in tank 89 times, and external atmosphere pressure is forced and made the water in tank 8 send into vacuum storage tank 1 by flow pipe 4 to supplement.The diameter of flow pipe 4 should be not less than the diameter of centrifugal pump suction hose 5, sufficient to ensure the water yield in vacuum storage tank 1.
Showing in figure, one end of centrifugal pump suction hose 5 is connected to the side of vacuum storage tank 1, and the other end is connected with centrifugal pump water sucking mouth, and centrifugal pump suction hose 5 provides water filling when starting by vacuum storage tank 1 to centrifugal pump 2.The diameter of centrifugal pump suction hose 5 selects to be determined by centrifugal pump water sucking mouth diameter, should be not less than centrifugal pump water sucking mouth diameter (unsuitable excessive), to improve the work efficiency of centrifugal pump 2.
Showing in figure, centrifugal pump outlet pipe 7 is arranged at the top of centrifugal pump 2, and centrifugal pump outlet pipe 7 carries out draining when centrifugal pump 2 runs well.
Showing in figure, vacuum storage tank 1 installation site and centrifugal pump 2 installation site are in same level, it is simple to centrifugal pump 2 water delivery.The centrifugal pump 2 vertical dimension from the tank water surface 9 is less than centrifugal pump 2 self water absorbing properties maximum vertical height, to ensure that centrifugal pump 2 can normal operation.
Figure shows, the diameter of flow pipe 4 more than or equal to the diameter of centrifugal pump suction hose 5, the displacement that output to guarantee flow pipe 4 per minute clockwise vacuum storage tank 1 is per minute more than centrifugal pump 2.
An embodiment of the present utility model is as follows:
The volume of vacuum storage tank 1 is 1m3；The model of centrifugal pump 2 is MD155-67 × 9；The diameter 159mm of centrifugal pump suction hose 5, long 3.5m；Flow pipe 4 diameter 180mm；Vacuum storage tank 1 and centrifugal pump 2 are arranged on same level position, and this position is 4.5 meters with lowest water level vertical dimension in tank 8, requires that its maximum water suction vertical depth is 5 meters in the installation instructions of centrifugal pump 2MD155-67 × 9.
Work process of the present utility model is as follows:
Centrifugal pump suction hose 5 of the present utility model is directly connected with vacuum storage tank 1, is constantly supplied water to centrifugal pump 2 by vacuum storage tank 1.Owing to vacuum storage tank 1 is a hermetic container, first time need to be added water to vacuum storage tank 1 by the artificial filler 6 of the water tank on vacuum storage tank 1 top when starting centrifugal pump 2, the air that water is filled it up with in final vacuum storage tank 1 is discharged, again the valve 3 that manually adds water of artificial for water tank filler 6 is closed, when centrifugal pump 2 starts to absorb water, the water yield of the vacuum storage tank 1 filling water will gradually decrease, now can form certain vacuum space (not being absolute vacuum), and external atmosphere pressure good general forces water in tank 8 to be admitted to vacuum storage tank 1 by flow pipe 4 to supplement, so circulation is constantly.
