Description
Technical field
The present invention relates to a kind of pump, be specifically related to a kind of wear-resisting long shaft submerged pump of water-saving type.
Background technology
Wear resistant submerged pump is widely used in the sewage disposal in the fields such as Coal Chemical Industry, metallurgy, environmental protection, electric power, has bigger market coverage.General abrasion resistant type submerged pump, in addition to material aspect uses wear-resistant material, mainly has two kinds of typical structures.One is cantilevered submerged pump, and this submerged pump advantage can meet the conveying of the higher medium of various solid content, and shortcoming is that under liquid, the degree of depth is limited, typically below 1.5 meters, adds override formats, but easily cause cavitation and resonance etc. under the conditions of Part load, and stability is not enough;Another kind is major axis class wear resistant submerged pump, the positions such as submerged pump intermediate support, lower support are rinsed by the flushing water or the clean liquid that generally individually use elevated pressures, the impurity particle that can solve of this flushing scheme enters supporting portion, extends submerged pump service life；Shortcoming is once to cut off the water supply or insufficient pressure etc., can damage middle and lower support friction pair at short notice, cause failure of pump, and the most a large amount of flushing waters can form the wasting of resources.
Summary of the invention
It is an object of the invention to provide a kind of wear-resisting long shaft submerged pump of water-saving type improving Main Shaft Service Life.
The technical scheme that the present invention takes is:
A kind of wear-resisting long shaft submerged pump of water-saving type, including the pump housing, water inlet it is provided with bottom the pump housing, the side of the pump housing is provided with outlet, outlet connects drain pipe, impeller it is provided with in the pump housing, pump housing end face connects pump cover, a vertical stay tube it is sealedly connected with on the end face of pump cover, prop up stay tube top and bearing housing is installed, the top of bearing housing is provided with motor, motor output end is connected by shaft coupling vertical main shaft, main shaft cross-under bearing housing successively, prop up stay tube, pump cover stretching into is connected with impeller in the pump housing, described main shaft is supported on stay tube through least one set bearing assembly, sealed by filler assembly between the pump cover of main shaft and the pump housing, closed cavity is formed between described stay tube and pump cover and bearing housing, described support tube side face is provided with water injection pipe, liquidometer and spout hole it is provided with below water injection pipe.
Further, described main shaft has three groups, upper, middle and lower bearing assembly to be supported in stay tube.
After taking above technical scheme, the invention have the benefit that
Clean water enters the container being made up of a relative closure a stay tube, filler, axle sleeve and gland etc. by water injection pipe, and overfall is arranged at a stay tube top, when clean water unnecessary after water filling completely overflows from it, prevents from impacting bearing box assembly；Clean water conservation intermediate support assembly and lower support assembly, it is ensured that main shaft runs in clean water with supporting member all the time, increases the service life.Leak on a small quantity from axle sleeve and filler when sealing water, by liquidometer detection water filling height, and periodically carry out moisturizing by water filling port, maintain certain liquid level difference, it is ensured that overpressure is consistently higher than pipe external pressure；When liquidometer monitoring pipe internal leakage increases, then periodically can change axle sleeve and filler, it is ensured that leakage rate maintains certain value.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the detailed description of the invention of the technical program is further described:
nullA kind of wear-resisting long shaft submerged pump of water-saving type，Including the pump housing 1，Bottom the pump housing 1,1 is provided with water inlet 2，The side of the pump housing 1 is provided with outlet 3，Outlet 3 connects drain pipe 4，Impeller 5 it is provided with in the pump housing 1，The pump housing 1 end face connects pump cover 6，A vertical stay tube 7 it is sealedly connected with on the end face of pump cover 6，Prop up stay tube 7 top and bearing housing 8 is installed，The top of bearing housing 8 is provided with motor 9，Motor 9 outfan is connected by shaft coupling 10 vertical main shaft 11，Main shaft 11 cross-under bearing housing 8 successively、Prop up stay tube 7、Pump cover 6 is also connected with impeller 5 in stretching into the pump housing 1，Described main shaft 11 is through upper、In、Lower three groups of bearing assemblies 12 are supported in stay tube 7，Sealed by filler assembly 13 between the pump cover 6 of main shaft 11 and the pump housing，Closed cavity is formed between described stay tube 7 and pump cover 6 and bearing housing 8，Described stay tube 7 side is provided with water injection pipe 14，Liquidometer 15 and spout hole 16 it is provided with below water injection pipe 14.
Claims (2)
