Technical Field

The invention relates to a rotor pump, in particular to a novel rotor pump with flanges.

Background

The rotor pump that uses now ubiquitous sealing washer life is short, the phenomenon of leaking appears after using the certain time, a small amount of normal work that does not influence the rotor pump that leaks, but get into the bearing along with water and can cause the destruction of bearing oil film, bearing wearing and tearing aggravation life-span shortens greatly, the phenomenon of leaking appears not long afterwards, before the life-span of sealing washer arrives, the bearing damages, finally cause the damage of rotor pump, cause very big influence to its life-span, and often early a small amount of the phenomenon of leaking does not influence the normal use of rotor pump.

Disclosure of Invention

The invention provides a novel rotor pump with flanges, aiming at solving the problem that the rotor pump is damaged before the service life of a sealing ring is reached, the invention provides a novel rotor structure, in order to prevent the liquid in a working chamber of a rotor from leaking into a bearing or a gear, the two sides of the rotor are additionally provided with an overhanging part and the flanges are arranged, so that the leaked liquid is thrown out to a chamber I or a chamber II along with the rotation of the flanges, and the purpose of prolonging the service life of the rotor pump is achieved.

The prior rotor pump realizes the sealing among the three working chambers through the radial sealing strips, and liquid passing through the sealing ring can quickly enter the bearing and the gear and enter the bearing, so that the problem caused by the sealing is the damage of a bearing oil film and the service life of the bearing oil film is shortened.

The solution of the invention is: punching is performed on the end cover, the cover plate and the cylinder body of the rotor pump, liquid breaking through the sealing ring is thrown to the first cavity and the second cavity through the flange, and the specific punching position of the first cavity and the second cavity is the lowest position of the end cover. After the rotor pump operates for a certain time, liquid in the rotor pump can break through the sealing ring, at the moment, the liquid is thrown out to the first cavity and the second cavity along with the rotation of the flange, the first cavity and the second cavity are connected through the middle hole, the liquid flows into the liquid recovery device through the drainage hole in the end cover, in the liquid flowing-in process, air pressure inside and outside the liquid recovery device can be balanced through the air vent, floating ball buoyancy in the liquid recovery device is gradually increased along with continuous flowing-in of the liquid, after the buoyancy is increased to a certain degree, the floating ball floats, the switch of the liquid outflow pipeline is opened, the liquid is sucked into the rotor pump again under the negative pressure action of the liquid inlet of the rotor pump, and the check valve on the liquid outlet pipeline is used for preventing the liquid in the liquid inlet of the rotor pump from entering the liquid recovery device.

The utility model provides a novel rotor pump with flange, includes eccentric shaft, triangle rotor, end cover, apron, cylinder body, its characterized in that it has the circular port to open on the apron, triangle rotor both sides all have overhanging portion, the overhanging portion is gone up and is installed the flange, still includes liquid recovery unit, liquid recovery unit installs in the outside of rotor pump, and liquid recovery unit's one end is connected with the end cover, the other end with the water inlet of cylinder body links to each other.

Furthermore, middle holes are formed in the lower portions of the cylinder body and the cover plate and are communicated with the first cavity and the second cavity.

Further, still install the sealing washer on the triangle rotor, the sealing washer is integral triangle-shaped structure, and its trilateral is circular-arc, has respectively opened a groove on three angles, there is the sealing washer filler sealing washer bottom, and the sealing washer filler has certain elasticity, and is right the holding power that the sealing washer provided, and the sealing washer filler can also play sealed effect, prevents that liquid is in the sealing washer bottom is passed.

Further, the sealing ring filler is an O-shaped ring.

Further, the liquid recovery device comprises a liquid inflow pipeline, a liquid storage tank, an air vent, a floating ball, a rotating rod, a liquid outflow pipeline and a one-way valve.

Furthermore, it has the drainage hole to open on the end cover, the liquid drainage that the sealing washer will be broken through in the drainage hole goes out the pump body, and its concrete position of punching is the lowest of cavity two.

Further, liquid inflow pipeline of the liquid recovery device is connected with the drainage hole in the end cover, the air vent can balance air pressure inside and outside the liquid recovery device, the floating ball can drive the rotary rod to rotate, the rotary rod turns on a switch of the liquid outflow pipeline while rotating, the one-way valve is installed on the liquid outflow pipeline, and the liquid flow direction of the one-way valve faces to the liquid inlet of the cylinder body.

Further, the sealing ring is made of nylon materials.

Furthermore, radial sealing strips are further installed on three corners of the triangular rotor, and springs are installed at the bottoms of the radial sealing strips to ensure that the radial sealing strips are always in contact with the cylinder body.

The novel rotor pump with the liquid recovery device has the beneficial effects that: when the sealing washer just begins to lose efficacy, during the condition that causes a small amount of liquid to leak, in order to prevent that liquid from getting into the bearing working chamber and causing the destruction to the bearing, through edge of a wing and cavity one and cavity two with liquid drainage feed liquid recovery unit, liquid recovery unit's effect prevents that liquid from causing the destruction to the surrounding environment, along with the buoyancy crescent of the floater in the liquid recovery unit, rotary rod rotary switch opens, liquid gets into liquid outflow pipeline and passes through the check valve, the final inlet that flows in the cylinder body. The service life of the rotor pump is prolonged, and the influence on the surrounding environment is reduced.
