Description

A high-efficiency and energy-saving centrifugal pump irrigation device

technical field

The utility model belongs to the technical field of water pump auxiliary facilities, in particular to a high-efficiency energy-saving centrifugal pump irrigation device with simple structure, reliable and convenient connection. the

Background technique

The centrifugal pump is a kind of pump that uses the centrifugal force generated by the water to rotate by the impeller. It has been widely used because of its simple structure, easy manufacture, convenient installation and adjustment, and stable flow and pressure. Before the centrifugal pump is turned on, the suction pipe and the pump must be filled with liquid, and the impeller rotates to shake off the water to form a vacuum to absorb water. If there is no water in the pump, the vacuum in the pump cavity cannot be formed, and water cannot be pumped. After the pump is turned on, the pump shaft drives the impeller and water to rotate at a high speed. Under the action of centrifugal force, the water flies away from the impeller and shoots out. The injected liquid gradually slows down in the diffusion chamber of the pump casing, and the pressure gradually increases, and then flows out of the pump outlet. , the discharge pipe flows out. At this time, a vacuum low-pressure area without air and liquid is formed at the center of the blade due to the liquid being thrown to the surroundings. The liquid in the liquid pool flows into the pump through the suction pipe under the action of the atmospheric pressure on the pool surface, and the liquid continues like this. It is continuously sucked up from the liquid pool and continuously flows out from the discharge pipe. Therefore, for centrifugal pumps that are used intermittently, due to the leakage of the check valve and other reasons, there is often no water in the pump and the suction pipe before the centrifugal pump is turned on, and it is turned on without irrigation. the

Before using the traditional centrifugal pump, it is necessary to remove the outlet pipe of the centrifugal pump and add water from the outlet of the centrifugal pump. It is inconvenient to take and install the outlet pipe, and it is time-consuming and laborious. For large centrifugal pumps, there is also a small submersible pump at the end of the outlet pipe A device for auxiliary irrigation, but the structure is complicated, the cost is high, and energy consumption is required, so it is difficult to apply to small and medium centrifugal pumps. the

Utility model content

The purpose of the utility model is to provide a high-efficiency energy-saving centrifugal pump irrigation device with simple structure and convenient and reliable connection. the

The purpose of this utility model is achieved in the following way: it includes a water suction pipe and a check valve, one end of the water suction pipe is connected to the water inlet of the centrifugal pump, and the other end is provided with a check valve and extends into the bottom of the pool, and the water suction pipe is set through the valve. It is higher than the water filling port of the centrifugal pump; the upper part of the water filling port is provided with a water storage tank and communicated with it, and the water storage tank is provided with a water supply pipe and a water supply valve connected to the outlet pipe of the centrifugal pump, and the valve and/or water supply valve are electric control valves And it is electrically connected with the control circuit of the centrifugal pump. the

The utility model sets a water filling port higher than the centrifugal pump on the water suction pipe of the centrifugal pump, and sets a check valve at the water intake end of the water suction pipe. For irrigation at the outlet of the centrifugal pump, it is necessary to remove the inconvenient connection of the outlet pipe. Further, the water filling port can be set in a funnel shape to facilitate water addition, or the water filling port can be connected to the water pipe, and the water can be directly poured through the water pipe; For the water pool, add water to the water storage tank in advance. When water needs to be filled, you only need to open the valve of the water filling port, and you can achieve multiple irrigations by adding water at one time; The water outlet of the pump or the water outlet pipe is connected, and the water is diverted to replenish the water storage tank while the centrifugal pump pumps water; The valve and liquid level switch of the water pipe are connected with the control circuit of the centrifugal pump. When pumping water, the control circuit can automatically fill and replenish water. The utility model has the advantages of simple structure, convenient and reliable connection. the

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings, but the utility model shall not be limited in any way, and any changes or improvements made based on the teaching of the utility model shall belong to the protection scope of the utility model. the

As shown in accompanying drawings 1 and 2, the utility model includes a water suction pipe 1 and a check valve 3. One end of the water suction pipe 1 is connected to the water inlet of the centrifugal pump, and the other end is provided with a check valve 3 and extends into the bottom of the pool. The water suction pipe 1 is set higher than the water filling port 2 of the centrifugal pump through the valve 4. the
