Abstract
The utility model relates to a three-blade pump mechanical sealing device, comprising a pump body on which a mechanical seal chamber is arranged. The front end of the mechanical seal chamber is provided with an end closure 11, and the back end is provided with a safe bush which slip joints to the main shaft of the three-blade pump. The end closure is provided with a stationary seat 14, a stationary ring 16 and a spring 12. The main shaft of the three-blade pump is provided with a rotating ring 7 and a rotating seat 8. The end closure is provided with a pressure water interface and a pressure water channel 15 which is connected and communicated with the mechanical seal chamber. The utility model adopts built-in type mechanical seal, which can intercept the fabric in the medium flowing into the mechanical seal chamber and improve the use effect and the service life of the mechanical seal.
Description
Technical field
The utility model relates to a kind of three blade pump mechanical seal device, and the sealing device is a kind of internally mounted mechanical seal, and its rotating ring contacts with medium, and spring does not contact with medium, prevents from that impurity such as mud, fiber from blocking spring spring compensation was lost efficacy.
Background technique
At present, the use three blade pump heats mud and discharges mostly in the sludge of sewage treatment plants digester, guarantees the normal operation of anaerobic digestion.Three blade pump commonly used is twin shaft, the twin vane-wheel rotor pump that Britain former SSP pump industry Co., Ltd makes, and model is GP601.Fig. 1 is the mechanical seal device structural drawing of three blade pump in the prior art, this mechanical seal device includes the pump housing 20, stationary ring seal ring 21, stationary seat 22, stationary ring 23, rotating ring 24, seal ring of moving ring 25, rotating seat 26, radial screw 27, wavy spring 28, spring seat 29, impeller is located at stationary ring leftward position 30 places, and motor output shaft 40 is in rotating ring one side.The mechanical seal of this pump is external mounted waveform spring mechanical seal device (its rotating ring does not contact with medium).The bad installation of the stationary ring of this mechanical seal, seal ring comes off easily, and it is low and pressure is uneven to bear pressure.Be in operation, because the tiny sand that contains in the medium of carrying (mud), fiber enter seal ring of moving ring through stationary seat axial clearance, fiber and mud make seal ring of moving ring ineffective, and the sealing rotating ring can not get compensation, cause to form the mud film between the dynamic and static ring, and very fast damage.And the mechanical seal place mud splash phenomenon of termination of pumping that the mechanical seal fault causes and on-the-spot pump takes place in aggravation, has a strong impact on the normal operation of sewage treatment works's mud district sludge digestion.Therefore, need to propose a kind of new three blade pump mechanical seal device.
Summary of the invention
The purpose of this utility model is to provide a kind of three blade pump mechanical seal device, the sealing device is a kind of internally mounted mechanical seal, its rotating ring contacts with medium, and spring does not contact with medium, prevents from that impurity such as mud, fiber from blocking spring spring compensation was lost efficacy.
The purpose of this utility model is realized by following technical proposals: a kind of three blade pump mechanical seal device, a pump housing is arranged, the described pump housing is provided with the mechanical seal chamber, this mechanical seal chamber front end is equipped with end cap, safe lining is equipped with in its rear end, this safe lining and described three blade pump main shaft are slidingly connected, stationary seat, stationary ring and spring are housed on the described end cap, on the described three blade pump main shaft 3 rotating ring, rotating seat are housed, press water interface 1 and press water passage are housed on the described end cap, and this press water passage is communicated with the mechanical seal chamber.
Compared with the prior art the utility model has following advantage:
1, because the utility model adopts internally mounted mechanical seal, and its rotating ring contact with medium, and spring does not contact with medium, prevents from that impurity such as mud, fiber from blocking spring to make spring compensate inefficacy.
2, the utility model injects mechanical closed chamber by the press water interface with press water, and the medium that flows into the mechanical seal chamber is played reverse impetus.
3, safe lining of the present utility model, the fiber inflow mechanical seal that can stop in the medium is indoor, improves mechanical seal using effect and working life.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1, be the mechanical seal device structural drawing (sectional view) of three blade pump in the prior art
Fig. 2, structural representation of the present utility model (sectional view)
Embodiment
Referring to Fig. 2, three blade pump mechanical seal device of the present utility model has a pump housing 5, and the described pump housing is provided with mechanical seal chamber 6, shows among the figure, is provided with the mechanical seal chamber at the left part of the three blade pump pump housing, and its right part is the position that impeller is installed.This mechanical seal chamber front end is equipped with end cap 11, and safe lining 17 is equipped with in its rear end, and this safe lining and described three blade pump main shaft 3 are slidingly connected, and makes the mechanical seal chamber form the chamber of sealing.In the present embodiment, the radial clearance of safe lining and described three blade pump main shaft is the 0.5-1 millimeter, and stationary seat 14, stationary ring 16 and spring 12 are housed on the described end cap, and rotating ring 7, rotating seat 8, radial screw 9, rotating ring O shape circle 10 are housed on the described three blade pump main shaft 3.Press water interface 1 and press water passage 15 are housed on the described end cap, and this press water passage is communicated with the mechanical seal chamber, and the press water interface is threaded with end cap, is provided with sealing gasket 2 therebetween.Described end cap is installed on the pump housing by screw 4, is provided with sealing gasket between the end cap and the pump housing.The left end 13 of described three blade pump main shaft is connected with drive motor power.
During the utility model operation, can on the press water interface, connect water in the high pressure, the middle water resources of utilizing sewage treatment works is to the indoor pressure flush of mechanical seal, current are through mechanical seal in being somebody's turn to do, flow out from the safety lining then, the medium that flows into the mechanical seal chamber is played reverse impetus, prevent that impurity such as mud, fiber from entering between the rotating ring of mechanical seal and the stationary ring and the spring place.Water also plays cooling action to mechanical seal in this high pressure.
The utility model has higher working life, and under the similarity condition, imported with original packaging mechanical seal device working life is half a year only, and the utility model can reach 2 years.
Use the utility model can save a large amount of funds, every pump is twin shaft two-shipper envelope, and imported with original packaging machine envelope price is 2.7 ten thousand a yuan/big cover, and the utility model only is 0.7 ten thousand a yuan/cover.
