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, in all trades and professions market that all is widely used.Work because submersible pump sinks in water, in order to prevent the lubricant contamination water source, the industry is to the restriction of having ready conditions of the friction lubricating of submersible pump.The submersible pump of supplying on market adopts water as the oiling agent of friction pair usually, and this kind water-supply structure is extremely simple, easily makes.Because the submersible pump working position sinks in water, obtain the water source very convenient, under atmospheric pressure water is secondary by the reserved passageway engaging friction, and what can reach expection falls the mill effect.But water is secondary by the gravity engaging friction under atmospheric pressure, and water flow is very little, and lubrication effect is not good enough.When particularly having bubble in the pond, in case bubble easily is adsorbed on inwall during with the current inlet passage, form the situation that bubble is blocked water flow.This situation occurs in the submersible pump working stage, easily produces high temperature and burns because friction pair can not get sufficient lubrication, and 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 active water lubrication formula submersible pump peculiar to vessel is proposed, this is rational in infrastructure, simple, introducing pump by fixed point contains setting-out friction pair is lubricated, this kind be the water supply form initiatively, high lubricating effect and reliable, the working life of effectively having improved submersible pump friction pair peculiar to vessel.
The present invention is achieved through the following technical solutions technical goal.
Active water lubrication formula submersible pump peculiar to vessel, it comprises adapter, base, three-way union, bleed valve, pump shaft, motor, carriage, pump cover, impeller and the pump housing.Described base, the pump housing, pump cover and carriage are connected upwards, and stack connects, the pump cover of plate-like is provided with between two parties endoporus mechanical seal axially is installed, at the axial bearing of installing in base middle part, impeller is placed in the pump housing, and pump shaft sequentially penetrates in mechanical seal, impeller and brearing bore and consists of pump structure.Its improvements are: described motor is placed on carriage, and the equipped Electricity Federation joint of the overhanging axle head of motor leans on mutually with the flange end of pump shaft is coaxial, connects into easy-to-dismount joint by pin between the two and connects structure.Described pump cover built-in radial passage is linked up pump housing water chamber and mechanical seal, and the radial passage consists of mechanical seal active water lubrication structure.In base also built-in channel link up bearing.The water chamber outer wall of the described pump housing is provided with interface three-way union is installed, and in T joint interface head-up, bleed valve is installed, and connects the built-in channel of base towards the adapter of lower interface installation, consists of bearing 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, and is easy to manufacture, easy to connect;
2, the water chamber that passage is linked up the pump housing is set respectively in pump cover and base, after pump operation, initiatively lubrication friction is secondary to carry the water of pressing, high lubricating effect and reliable.
Description of drawings
Fig. 1 is structural profile schematic diagram of the present invention.
Embodiment
The invention will be further described with reference to the accompanying drawings for the below.
Active water lubrication formula submersible pump peculiar to vessel shown in Figure 1, it comprises adapter 1, base 2, three-way union 3, bleed valve 4, pump shaft 5, motor 6, carriage 7, pump cover 8, impeller 9 and the pump housing 10.Described base 2, the pump housing 10, pump cover 8 are connected successively upwards folded frame and are connected with carriage, the pump cover 8 of plate-like is provided with between two parties endoporus mechanical seal 8.2 axially is installed, and in the base 2 axial installation shaft 2.2 in middle part, 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 the top order and consists of pump structure.Described motor 6 is placed on carriage 7, and the equipped Electricity Federation joint 6.1 of the overhanging axle head of motor 6 leans on mutually with the flange end of pump shaft 5 is coaxial, connects by pin 6.2 between the two, and it is simple that this kind joint connects structure, is convenient to assembling, is convenient to dismounting.When breaking down, save the connection structure by dismounting and realize that motor 6 and pump partly separate, can keep in repair targetedly or change component according to the fault point, thereby save maintenance load and the cost of changing component.The radial passage 8.1 of the built-in communication pump housing 10 water chambers of described pump cover 8 and mechanical seal 8.2, radial passage 8.1 consist of mechanical seal 8.2 active water lubrication structures.In base 2 also built-in channel 2.1 link up bearings 2.2.The water chamber outer wall of the described pump housing 10 is provided with interface installation three-way union 3, and bleed valve 4 is installed in three-way union 3 interface up, connects the built-in channel 2.1 of base 2 towards the adapter 1 of lower interface installation, consists of bearing 2.2 active water lubrication structures.Pump operation rear tube 1 is drawn from the pump housing 10 water chambers and is carried setting-out, through the built-in logical 2.1 active lubricating bearings 2.2 of base 2.The present invention is by pre-set path and external pipe in pump, accomplish from pump draw in water cavity pressure is arranged water to mechanical seal 8.2 and bearing 2.2, 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 more than 3 times than prior art products, so it is supporting to be particularly suitable for the naval vessel.
