Background

The submersible pump is a water lifting machine with a motor and a water pump directly connected into a whole to be submerged into water for working, and has the advantages of simple structure, high unit efficiency, low noise, safe and reliable operation and convenient installation and maintenance. The flow control of present immersible pump is generally realized through the valve, but to some places of being difficult for installing the valve, if the inflow of uncontrolled diving pump, then the overload phenomenon appears in the water pump easily, leads to power promotion impeller to damage the normal life who influences the water pump.

Disclosure of Invention

The utility model aims at providing a to the above-mentioned problem that exists among the prior art, provide a structural control inflow flow through two mutual misplacements of grid realizes anti-overloading's immersible pump.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a grid dislocation overload prevention immersible pump, includes motor portion and installs the water inlet joint in motor portion, the motor shaft axial extension of motor portion is used for with pump body impeller connection, the pump body links firmly in the other end of water inlet joint, a serial communication port, the water inlet department outer lane axial extension of water inlet joint forms spacing step, the outer lane card of spacing step is equipped with two grid pieces that parallel each other, the grid piece on the even vertical filter flume of having seted up in interval, U type groove has been seted up to both sides about the tip of grid piece, the water inlet joint on radially be provided with U type groove position matched with fixed screw, two the grid piece pass through U type groove structure and fixed screw cooperation formation dislocation each other.

The technical effects of the grid dislocation overload prevention submersible pump are as follows: u type groove is used for adjusting the fixed position between grid piece and the fixed screw, makes the filter cell of two grid pieces misplace each other to adjust the sectional area of water inlet, the interval size of water inlet can be according to required actual flow control, the upper end of grid piece is passed through the stair structure and is supported, the lower extreme supports through the festival outer fringe of intaking, the generous convenient installation of installation space surplus, and the structure of grid piece filter cell dislocation can also play effectual filterable effect and prevent that impurity from getting into in the pump head.

In foretell grid dislocation overload prevention immersible pump, be provided with annular sealed pad on the terminal surface of motor portion, the bottom of water inlet festival upwards caves in and forms round platform form and with sealed seal groove that gasket structure matched with.

In the above-mentioned grid dislocation overload prevention submersible pump, the outside of the motor part is provided with a wiring device for wire connection.

In the above-mentioned grid dislocation overload prevention submersible pump, the grid pieces are made of aluminum, iron or stainless steel.

Compared with the prior art, the grid dislocation overload prevention submersible pump has the following advantages:

1. the size of the water inlet is adjusted by controlling the dislocation range of the two grating pieces, so that the adjusting structure is convenient and has wide applicability;

2. the grid sheets staggered with each other form a filtering structure, a filter screen is not required to be arranged at the water inlet joint, and the whole assembly is more convenient.
