Wherein L1 is the highest start level and L2 is the lowest start level.

Detailed Description

The utility model discloses do not receive the restriction of following embodiment, can be according to the utility model discloses a technical scheme and actual conditions determine concrete implementation.

In the present invention, for convenience of description, the description of the relative position relationship of the components is described according to the layout mode of the attached drawing 1 in the specification, such as: the positional relationship of front, rear, upper, lower, left, right, etc. is determined in accordance with the layout direction of fig. 1 of the specification.

The invention will be further described with reference to the following examples and drawings:

as shown in fig. 1, the suction tube type submerged pump of the submersible pump comprises a suction tube type submerged pump 1 and a liquid storage tank 2, a check valve 4 is fixedly installed at a suction tube 3 of the suction tube type submerged pump 1, an upper liquid outlet pipe 6 is fixedly communicated with a liquid outlet end 5 of the liquid outlet pipe of the suction tube type submerged pump 1, a liquid filling pipe 7 is communicated between the upper liquid outlet pipe 6 and a liquid outlet end at the bottom of the liquid storage tank 2, and a valve 8 is fixedly installed on the liquid filling pipe 7.

The utility model discloses before opening the pump, utilize the working solution in the liquid storage pot 2 to carry out the pump priming, normally beat liquid after the pump starts, and fill liquid storage pot 2 with the working solution after, the pump priming when treating the pump of opening next time realizes that equipment opens at any time and stops.

When the pump is filled, the check valve 4 can prevent liquid from being discharged through the suction pipe 3, and when the check valve 4 is selected, the resilience force of the check valve 4 in the working liquid is required to be larger than the buoyancy force of the working liquid to the valve core of the check valve 4.

When the pump is filled, the valve 8 on the liquid filling pipe 7 is opened to fill the pump, and after the liquid storage tank 2 is filled with the working liquid after the pump is started, the valve 8 is closed.

After the suction pipe type submerged pump 1 works normally, liquid enters from the suction pipe 3 and is discharged from the upper liquid outlet pipe 6.

The utility model discloses a start highest liquid level L1, start minimum liquid level L2 and as shown in figure 1.

The utility model discloses a reform transform on the basis of current suction tube submerged pump, through setting up liquid storage pot 2, going up drain pipe 6, liquid pipe 7 etc. and enable the utility model discloses when being in the position below impeller 9 department, normally start, and start the liquid level and can fall to below the check valve 4.

The suction tube submerged pump 1 of the above-mentioned pump can be further optimized or/and improved according to the actual need:

as shown in the attached figure 1, an exhaust valve 10 is arranged at the top of the liquid storage tank 2.

When the valve 8 on the liquid filling pipe 7 is opened for filling, the exhaust valve 10 is opened, the vacuum influence on the filling is avoided, after the suction pipe type submerged pump 1 operates normally, the liquid storage tank 2 is filled with liquid, gas in the liquid storage tank 2 is discharged through the exhaust valve 10, the liquid storage amount of the liquid storage tank 2 is prevented from being influenced by the fact that the gas is not discharged, and the exhaust valve 10 is closed when the liquid storage tank 2 is filled with the liquid.
