The channel and the external channel are preset in the pump, water with pressure is guided into the mechanical seal and the bearing from the pump body water outlet cavity, the friction pair is subjected to full water lubrication in the operating stage, and the submersible pump is small in abrasion, high in transmission efficiency and long in service life and is particularly suitable for ship and warship matching.
Description
Technical field
The present invention relates to a kind of friction lubricating structure of hydraulic machinery, specifically, the present invention relates to a kind of submersible pump peculiar to vessel of water lubrication friction pair.
Background technique
Submersible pump is one of a kind of general service pump product, to be all widely used market in all trades and professions.Work because submersible pump sinks in water, in order to prevent lubricant contamination water source, the friction lubricating of the industry to submersible pump is had ready conditions restriction.The submersible pump that market is supplied adopts water as the oiling agent of friction pair usually, and this kind of water-supply structure is extremely simple, easily manufactures.Because submersible pump working position sinks in water, obtain water source very convenient, under atmospheric pressure water is secondary by reserved passageway engaging friction, and what can reach expection falls mill effect.But water is secondary by gravity engaging friction under atmospheric conditions, and water flow is very micro-, and lubrication effect is not good enough.When particularly there is bubble in pond, be easily adsorbed on inwall with current inlet passage once bubble, form the situation that bubble blocks water flow.This situation occurs in submersible pump working stage, and easily produce high temperature because friction pair can not get sufficient lubrication and burn, severe patient causes friction pair to lose efficacy.
Summary of the invention
The present invention is mainly for the deficiencies in the prior art, a kind of submersible pump for active water lubrication type ship is proposed, this is rational in infrastructure, simple, contain setting-out by fixed point introducing pump to lubricate friction pair, this kind initiatively supplies water form, high lubricating effect and reliable, effectively improves the working life of submersible pump friction pair peculiar to vessel.
The present invention is achieved through the following technical solutions technical goal.
Submersible pump for active water lubrication type ship, it comprises adapter, base, three-way union, bleed valve, pump shaft, motor, bracket, pump cover, impeller and the pump housing.Described base, the pump housing, pump cover and bracket upwards superpose connection successively, the pump cover of plate-like is provided with endoporus between two parties and axially installs mechanical seal, bearing is axially installed by portion in the base, and impeller is placed in the pump housing, and pump shaft order penetrates in mechanical seal, impeller and brearing bore and forms pump structure.Its improvements are: described motor is placed on bracket, and the Electricity Federation joint that the overhanging axle head of motor is equipped with coaxially leans on mutually with the flange end of pump shaft, connect into easy-to-dismount joint connection structure between the two by pin.Described pump cover built-in radial passage links up pump housing water chamber and mechanical seal, and radial passage is formed mechanical seal active water lubrication structure.In base, also built-in channel links up bearing.The water chamber outer wall of the described pump housing is provided with interface and installs three-way union, in T joint interface head-up, install bleed valve, and the adapter of installing towards lower interface connects the built-in channel of base, structure matched bearings active water lubrication structure.
Bearing in said structure is rolling bearing.
The present invention compared with prior art, has following good effect:
1, waterflood path is simple and reasonable for structure, easy to manufacture, easy to connect;
2, passage is set respectively in pump cover and base and links up the water chamber of the pump housing, after pump operation, carry the water active lubrication friction pair of pressure, high lubricating effect and reliable.
Accompanying drawing explanation
Fig. 1 is structural profile schematic diagram of the present invention.
Embodiment
The invention will be further described with reference to the accompanying drawings below.
Submersible pump for active water lubrication type ship shown in Fig. 1, it comprises adapter 1, base 2, three-way union 3, bleed valve 4, pump shaft 5, motor 6, bracket 7, pump cover 8, impeller 9 and the pump housing 10.Described base 2, the pump housing 10, pump cover 8 and bracket 7 successively upwards superimposed be connected, the pump cover 8 of plate-like is provided with endoporus between two parties and axially installs mechanical seal 8.2, and axial installation shaft 2.2 in the middle part of base 2, the present embodiment middle (center) bearing 2.2 is rolling bearing.In advance impeller 9 is placed in the pump housing 10, pump shaft 5 penetrates mechanical seal 8.2, impeller 9 and bearing 2.2 endoporus from top order and forms pump structure.Described motor 6 is placed on bracket 7, and the Electricity Federation joint 6.1 that the overhanging axle head of motor 6 is equipped with coaxially leans on mutually with the flange end of pump shaft 5, is connected between the two by pin 6.2, and this kind of joint connection structure is simple, is convenient to assembling, is convenient to dismounting.When a failure occurs it, realize motor 6 by dismounting joint connection structure and separate with pumping section, can keep in repair targetedly according to fault point or change component, thus save maintenance load and the cost changing component.The radial passage 8.1 of the described pump cover 8 built-in communication pump housing 10 water chamber and mechanical seal 8.2, radial passage 8.1 is formed mechanical seal 8.2 active water lubrication structure.In base 2, also built-in channel 2.1 links up bearing 2.2.The water chamber outer wall of the described pump housing 10 is provided with interface and installs three-way union 3, in three-way union 3 interface upward, install bleed valve 4, and the adapter 1 of installing towards lower interface connects the built-in channel 2.1 of base 2, structure matched bearings 2.2 active water lubrication structure.Pump operation rear tube 1 is drawn and is carried setting-out from the pump housing 10 water chamber, through the built-in logical 2.1 active lubrication bearings 2.2 of base 2.The present invention is by pre-set path and external pipe in pump, accomplish there is the water of pressure in mechanical seal 8.2 and bearing 2.2 from pumping in water cavity to draw, guarantee that these two friction pairs obtain abundant water lubrication in the submersible pump operation phase, remain normal operation, abrasion are few, transmission efficiency is high, the most important thing is that working life is longer than prior art products more than 3 times, so it is supporting to be particularly suitable for naval vessel.
