Abstract
The utility model discloses a water supply device of a centrifugal pump, belonging to the technical field of water supply devices. The water supply device comprises a water inlet tube connected with a water inlet of the centrifugal pump, and a water outlet tube connected with a water outlet of the centrifugal pump. The water outlet tube is connected with a water storage tank with a water outlet. The water storage tank is communicated with the water inlet tube through a drainage tube. An electromagnetic stop valve is arranged on the drainage tube. The maximum inner diameter of the drainage tube is smaller than the maximum inner diameter of the water inlet of the centrifugal pump. A water flow switch is arranged at the upstream on the drainage tube of the water inlet tube. A check valve is arranged between the water flow switch and the drainage tube. The water flow switch is electrically connected with the electromagnetic stop valve. According to the water supply device, as the maximum inner diameter of the drainage tube is smaller than the maximum inner diameter of the water inlet of the centrifugal pump, water is not necessarily filled manually before the centrifugal pump is started, so that the device is convenient to use and time-saving, and the work efficiency is improved.
Description
Technical field
The utility model belongs to the water supply equipment technical field, relates in particular to a kind of centrifugal pump water supply installation.
Background technique
In agricultural irrigation and industrial processes, need the water in the water sources such as well, pond be pumped in supply channel by water pump.Centrifugal pump due to compact structure, flow evenly, smooth running, vibration is little, equipment is installed, the Maintenance and Repair expense is low etc., and advantage is widely used.
But, because centrifugal pump is to form vacuum dehydration by impeller inlet, therefore before startup, must in pump and in intake pipe, pour into diversion, or bleed with vacuum pump, forming vacuum to discharge air, and pump case and strictly sealing of intake pipe, must not leak gas, otherwise can not form vacuum, and then can't work, in actual use, be difficult to deposit water in the intake pipe of centrifugal pump upstream, often cause all needing the diversion of first annotating before the each startup of centrifugal pump, make troubles to production.
The model utility content
Technical problem to be solved in the utility model is: a kind of centrifugal pump water supply installation is provided, to solve centrifugal pump, needs the artificial diversion before startup, the technical problem of making troubles to production.
For solving the problems of the technologies described above, the technical solution of the utility model is: the centrifugal pump water supply installation, comprise the intake pipe be connected with the water intake of described centrifugal pump and the outlet pipe be connected with the water outlet of described centrifugal pump, described outlet pipe connects the water storage tank with a water outlet, between described water storage tank and intake pipe, by a drainage tube, be communicated with, described drainage tube is provided with electromagnet cut off valve, and the maximum inner diameter of described drainage tube is less than the maximum inner diameter of the water intake of described centrifugal pump; Be positioned at described drainage tube upstream position on described intake pipe and be provided with water switch, between described water switch and described drainage tube, be provided with safety check, described water switch and described electromagnet cut off valve are electrically connected to.
As a kind of improvement, between described electromagnet cut off valve and water storage tank, be provided with throttle element.
After having adopted technique scheme, the beneficial effects of the utility model are: because described drainage tube is provided with electromagnet cut off valve, the maximum inner diameter of described drainage tube is less than the maximum inner diameter of the water intake of described centrifugal pump, described intake pipe is provided with water switch, be provided with safety check between described water switch and described drainage tube, described water switch and described electromagnet cut off valve are electrically connected to, thereby centrifugal pump is when starting, when the water flow in intake pipe is zero, water switch is controlled electromagnet cut off valve and is opened, water storage tank is communicated with water intake, the centrifugal pump running, because the maximum inner diameter of drainage tube is less than the maximum inner diameter of the water intake of centrifugal pump, the water flow that water in water storage tank enters centrifugal pump does not reach the normal operation water flow of centrifugal pump, thereby centrifugal pump can be extracted into water storage tank by the air in intake pipe, then air is discharged through water storage tank, water in water source is through intake pipe, safety check enters centrifugal pump, the water flow of the intake pipe of water switch detection simultaneously is non-vanishing, the control electromagnet cut off valve is closed, water storage tank and water intake disconnect, the water that prevents water storage tank refluxes, give full play to the high workload efficiency of centrifugal pump, water in water source and then by centrifugal pump and water storage tank, then from the water outlet of water storage tank, enter exterior line, guaranteed that centrifugal pump needn't manually pour into diversion before startup, easy use, saved the time, improved working efficiency.
Owing between described electromagnet cut off valve and water storage tank, being provided with throttle element, thereby can discharge fast the air in intake pipe.
