Abstract
The utility model discloses a high cost performance mechanical seal device for a corrosion resistant pump. The high cost performance mechanical seal device comprises a moving ring (1), a moving ring seat (2), a transmission seat (4) and a spring, wherein the moving ring seat (2) and the transmission seat (4) are both sleeved on the moving ring (1), one end of the spring is connected with the moving ring seat (2), the other end of the spring is connected with the transmission seat (4), and the moving ring seat (2) is connected with the transmission seat (4) through a transmission screw (5). By means of the structure, the high cost performance mechanical seal device is simple in whole structure and convenient to achieve. When one part is damaged, recycling can be conducted after corresponding replacement, cost is saved, only parts contacting highly corrosive solution are made of corrosion resistant material, and therefore environment pollution caused by waste material produced by application of the high cost performance mechanical seal device is reduced.
Description
Technical field
The utility model relates to a kind of sealing configuration, specifically anti-corrosive pump high performance-price ratio mechanical seal device.
Background technique
During the centrifugal pump fed sheet of a media, its pump housing and pump shaft exist certain gap because having the relative movement between, and in order to stop medium from the clearance leakage between the pump housing and the pump shaft, centrifugal pump all is provided with seal arrangement.When centrifugal pump was used for the industry such as chemical industry, chemical fibre, medicine, it was usually used in carrying and has the very medium of severe corrosive, and such as severe corrosive solution such as sulfuric acid, nitric acid, caustic soda, this has good decay resistance with regard to the seal arrangement that needs centrifugal pump.Decay resistance for the seal arrangement that guarantees centrifugal pump, the existing whole polytetrafluoroethylmaterial material of highly corrosion resistant that adopts of seal arrangement that is used for the centrifugal pump of the industries such as chemical industry, chemical fibre, medicine is made, the existing seal arrangement of corrosion resisting centrifugal pump that is used for is because being subjected to the restriction of self structure, when local damage, need whole the replacement, seal arrangement after the replacement can not reuse by maintenance, a large amount of teflon is discarded, and discarded teflon in the nature degraded slowly, and this just causes environmental pollution serious.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of anti-corrosive pump high performance-price ratio mechanical seal device is provided, it can carry out the seal arrangement that damages reusing after replace the part, and can reduce the slowly use amount of resistant material of degrading, but and then environmental contamination reduction.
The purpose of this utility model is achieved through the following technical solutions: anti-corrosive pump high performance-price ratio mechanical seal device, comprise rotating ring, rotating seat, retainer and spring, described rotating seat and retainer all are set on the rotating ring, described spring one end is connected on the rotating seat, its the other end is connected on the retainer, described rotating seat connects by the transmission screw with retainer, and described transmission screw two ends embed respectively in rotating seat and the retainer.The utility model is when concrete the application, and moving ring sleeve is located on the pump shaft of centrifugal pump.
Anti-corrosive pump high performance-price ratio mechanical seal device; also comprise the spring protection shell; described spring protection shell is made of cylinder and the annular cover plate that is connected to cylinder one end; the annular cover plate of spring protection shell is set on the rotating ring between rotating seat and the retainer, and the end that the connecting end of described spring and retainer and transmission screw embed retainer all passes the spring protection shell.The purpose that the utility model arranges the spring protection shell is spring spacing in the spring protection shell.
Because carbon steel and stainless steel material are convenient to draw materials and recycle, environmentally safe, and cost is lower than polytetrafluoroethylmaterial material, as preferably, described rotating seat and spring protection shell all adopt carbon steel or stainless steel material to make.
Because rotating ring can contact with deep-etching solution, in order to guarantee decay resistance of the present utility model, described rotating ring adopts polytetrafluoroethylmaterial material to make.
Compared with prior art, the utlity model has following beneficial effect: the utility model comprises rotating ring, rotating seat, retainer and spring, wherein, rotating seat and retainer all are set on the rotating ring, spring one end is connected on the rotating seat, its the other end is connected on the retainer, rotating seat connects by the transmission screw with retainer, the utility model adopts said structure, overall structure is simple, be convenient to realize that each parts independently exists in the utility model, when single part damages, can carry out reusing after replace the part, and the utility model can adopt the rotating ring that contacts with strong corrosive media the polytetrafluoroethylmaterial material of degrading slowly to make, other parts then adopt cost to be lower than polytetrafluoroethylmaterial material and the material being convenient to recycle is made, and this has just reduced environmental pollution, has reduced cost.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation.
The corresponding name of reference character is called in the accompanying drawing: 1, rotating ring, 2, rotating seat, 3, the spring protection shell, 4, retainer, 5, the transmission screw.
Embodiment
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing, but mode of execution of the present utility model is not limited to this.
Embodiment:
As shown in Figure 1; anti-corrosive pump high performance-price ratio mechanical seal device; comprise rotating ring 1, rotating seat 2, spring protection shell 3, retainer 4 and spring; wherein; rotating seat 2 and retainer 4 all are set on the rotating ring 1, and spring one end is connected on the rotating seat 2, and its other end is connected on the retainer 4; rotating seat 2 is connected with retainer by 5 connections of transmission screw, and transmission screw 5 two ends embed respectively in rotating seat 2 and the retainer 4.For the decay resistance that guarantees present embodiment with save cost, as preferably, rotating ring 1 adopts polytetrafluoroethylmaterial material to make, and rotating seat 2 and spring protection shell 3 all adopt carbon steel or stainless steel material to make.
As mentioned above, then can well realize the utility model.
