Description
Technical field
A kind of peripheral pump is the utility model is related to, particularly a kind of vertical single stage clear water peripheral pump (TWP pumps).
Background technology
Peripheral pump is usually used in the supporting of boiler feedwater, in shipbuilding, light textile, chemical industry, metallurgy, machine-building, aquaculture, disappears
Departments such as anti-voltage stabilizing, heat-exchanger, the long-range sprinkling irrigation of agricultural etc. are all widely used.Due to peripheral pump have it is small, again
The characteristics of light is measured, there is great superiority in marine installation.
As shown in Figure 1, existing vertical single stage clear water peripheral pump include spindle assemblies, pump case, pump cover, the big support of bearing and
The small support of bearing, the big support of bearing and the small support of bearing are bolted on the left and right sides of pump case, big axis respectively
Hold stent and compress pump cover at the same time, the spindle assemblies include main shaft, impeller and bearing.The spindle assemblies are symmetrical structure
(except clamp spring), the impeller are a disks, and the blade on disk is radial evenly distributed.Formed between pump case and impeller
Annular channel, suction inlet and outlet are at the excircle of impeller.There is partition plate between suction inlet and outlet, thus will suction
Mouth and outlet are kept apart.Since existing spindle assemblies structure is more complicated, cause manufacture cost higher；Again due to impeller channel
On impeller muscle piece unreasonable structure, cause lift and flow performance poor, less efficient, efficiency not more than 55%,
The efficiency of most of peripheral pumps hampers peripheral pump and develops to high-power direction in 20%-40%.
Utility model content
To solve the above problem existing in the prior art, the utility model to design it is a kind of manufacture of low cost and lift and
The vertical single stage clear water peripheral pump that performance increases substantially.
To achieve these goals, the technical solution of the utility model is as follows：A kind of vertical single stage clear water peripheral pump, including
Spindle assemblies, pump case, pump cover, the big support of bearing and the small support of bearing, the big support of bearing and the small support of bearing lead to respectively
The left and right sides that bolt is fixed on pump case is crossed, the big support of bearing compresses pump cover at the same time, and the spindle assemblies include main shaft, impeller
And bearing, the impeller are fixed on the middle part of main shaft by key and jackscrew, the both sides of impeller be symmetrical arranged successively mechanical seal,
Machine sealed cover, water proof rubber pad, bearing and bearing gland, the machine sealed cover in left side are fixed on pump cover by studs, right
The machine sealed cover of side is fixed on pump case by studs, and the bearing of left and right ends is embedded in the big support of bearing and small axis respectively
Hold in stent, and fixed by bearing gland with bolt；Clamp spring is also set up on the inside of right end bearing；
The impeller includes a disk, and the blade on disk is radial evenly distributed, is formed between pump case and impeller
Annular channel；
The arc radius in the annular channel exit is R30mm, and annular channel spacing is 8mm, and eddy area is
500mm2More than.
Further, the big support of bearing shape and size and the installation site of peripheral pump match.
Further, the small support of bearing shape and size and the installation site of peripheral pump match.
Further, the edges and corners circular arc inside the pump case is excessive.
Further, the mechanical seal is standard component, is sealed using U1527 series mechanicals.
Further, the pump case endoporus is φ 45mm.
Compared with prior art, the utility model has the advantages that：
1st, existing peripheral pump all uses packing seal, therefore inefficiency, and can not ensure sealing performance, causes vortex
Pump leak, flow is small, pressure is low；After the utility model uses mechanical seal, impeller is flexible in pump case inner rotation, sealing performance
It is good, it can reach zero leakage；Efficiency can reach 50%~60%.
2nd, the utility model compared with prior art, changes the regional area size of impeller；By annular channel exit
Arc radius increases to R30mm by original R25mm, lifts the kinetic energy of current；Annular channel spacing is by original 6mm increases
8mm, makes the flow of peripheral pump increase；Eddy area is by original 400mm2Increase to 500mm2More than, increase the suction of peripheral pump
Add；As a result of above measure, the flow and lift for making peripheral pump greatly improve；Flow can reach 60L/s, and lift may be up to
250m。
3rd, it is excessive using circular arc at the pump case inside corner of the utility model, it can greatly reduce the resistance of current, improve
The work efficiency of peripheral pump, reduces energy loss of the current in peripheral pump.
4th, the mechanical seal of the utility model is standard component, using U1527 series, it can be achieved that the effect of peripheral pump zero leakage
Fruit.
5th, the pump case endoporus of the utility model increases to φ 45mm by φ 32mm, easy to the integral installation of peripheral pump.
6th, existing peripheral pump is because itself is excessively compact, thus peripheral pump assembling is difficult.The utility model is with according to vortex
The characteristics of pump, 10mm is increased by support of bearing outside diameter, and by screw hole edge evagination, to facilitate the dismounting of bolt.At the same time because original
Packing seal installation trouble, and be changed to mechanical seal, facilitate the assembling of peripheral pump.
