Description

Water pump simple water filling device

1. Fields:

The utility model relates to a simple water filling device for a water pump, which belongs to the field of water conservancy.

2. Background technology

For small or infrequently used centrifugal pump stations, especially in the vast rural areas, when irrigating crops, the water pumps often use the flow mode of operation. Since there is no available power supply, most of them use internal combustion engines as power, and it is impossible to use the vacuum pump water filling system. For water filling, the bottom valve (shower head) can only be installed at the inlet of the water pump, and the water pump is filled manually. Due to the large loss of water head at the bottom valve, the operating efficiency is reduced, and sometimes the bottom valve is not closed tightly or The phenomenon of being unable to close causes the bottom valve to leak water, which cannot meet the needs of water filling of the water pump. It is inconvenient to use and makes water filling of the water pump more difficult. The inventor has worked on the water filling equipment of the pump station float valve type automatic sealing water tank (ZL201110332781.0), the pump station inlet and exhaust valve type automatic sealing water tank water filling equipment (ZL201220068218.7), the water pump traction bottom valve water filling device (ZL201520755306. 8) and on the basis of the development of the valve-blocking pump station water filling device (ZL201520755308.7), a simple, practical and easy-to-operate water pump simple water filling device is provided.

3. Contents of the invention

In order to facilitate the water filling of the external flow water pump and reduce the energy loss caused by the bottom valve, the utility model provides a simple water filling device for the water pump on the basis of the previously developed water filling equipment.

To make the water body in the water tank form a certain degree of vacuum; the vertical height between the top of the water tank and the water level of the water source is less than 10m, and the bottom of the water tank is higher than the water inlet pipe of the water pump and the top of the water pump; the water tank is filled and exhausted through the water tank and the water pump The pipe is connected to the water filling hole of the water pump; the water filling hole of the water pump is located at the top of the pump cavity; the water filling exhaust pipe of the water tank is connected with the water filling exhaust pipe of the water pump through a quick joint; the water filling exhaust pipe of the water pump is installed with a filling The water exhaust pipe gate valve; the water level gauge is fixed on the outer wall of the water tank, and the upper and lower ports of the water level gauge are connected with the inner cavity of the water tank. The water inlet of the water pump is connected with the water source through the water inlet pipe, the water outlet of the water pump is connected with the water outlet pipe, and the water outlet pipe is provided with a water outlet pipe gate valve.

When in use, first connect the water filling and exhaust pipe of the water tank with the water pump water filling and exhaust pipe with a quick connector, close the gate valve of the water filling and exhaust pipe, open the sealing cover, and use the water filling funnel to fill the water tank until it is full. Plug the irrigation funnel with the airtight cap. Before the water pump works, close the gate valve of the water outlet pipe, open the gate valve of the water filling and exhaust pipe, and under the action of gravity, the water will be automatically poured into the water pump, the water inlet pipe of the water pump and before the gate valve of the water outlet pipe through the water filling exhaust pipe of the water tank and the water filling exhaust pipe of the water pump. In the outlet pipe of the water tank, as the water level in the water tank drops, the pressure in the water tank decreases, forming a certain vacuum. As the water level in the water inlet pipe, the water pump inner cavity and the water outlet pipe continues to rise, the internal gas is discharged into the upper part of the water tank through the water pump water filling exhaust pipe and the water tank water filling exhaust pipe. When the water inlet pipe of the water pump, the inner chamber of the water pump and the outlet pipe before the outlet pipe gate valve are all filled with water, the whole system will reach a state of vacuum balance, and the water level in the water tank will no longer drop at this time (observed by the water level gauge), so that After completing the water filling process of the water pump, close the gate valve of the water filling and exhaust pipe to start the water pump; after closing the gate valve of the water filling and exhaust pipe, open the quick connector to remove the water tank or not, depending on the actual situation The situation decides that it no longer affects the normal operation of the water pump.

Beneficial effect:

The utility model can well solve the water filling problem of the water pump, not only saves the bottom valve, but also saves the vacuum pump unit, and can realize energy-saving operation. The simple water filling device of the water pump has laid a solid foundation for better technical transformation of the pumping station.
