Another defective that the high temperature of prior art, high-pressure water heating recycle pump mechanical seal device exist is: the mechanical seal device blowdown mechanism of not exitting, the venting blowdown will be carried out in the water pump pipe-line system, operating difficulties, can not observe fluid temperature in the Seal cage at any time, simultaneously, in Seal cage, stockpile the working life that sewage can influence mechanical seal for a long time.
The model utility content
Main purpose of the present utility model is to overcome the major defect that exists in the above-mentioned prior art, and high temperature, the high-pressure water heating recycle pump mechanical seal device of a kind of good cooling results, long service life is provided.
The technological scheme that realizes above-mentioned purpose is as follows:
A kind of high temperature, high-pressure water heating recycle pump mechanical seal device, comprise the sealing cover that links to each other with the pump housing, in sealing cover, be provided with Seal cage, in Seal cage, be provided with stationary ring, rotating ring, throw-out collar, end, the outside at sealing cover is provided with positioning block, also is respectively arranged with the cooling liquid inlet and the cooling liquid outlet that are communicated with Seal cage on described sealing cover.
Further, described cooling liquid inlet and cooling liquid outlet all are provided with at rotating ring and stationary ring side.
In order to overcome another defective that exists in the prior art, high temperature of the present utility model, high-pressure water heating recycle pump mechanical seal device also comprise venting blowdown mechanism, described venting blowdown mechanism comprises venting drain pipe and stop valve disposed thereon, one end of described venting drain pipe links to each other with cooling liquid outlet, and the other end communicates with the external world.
Compared with prior art, the utlity model has following beneficial effect:
1, change the cooling water water inlet direction of mechanical seal, inflow heat exchanger after the high-temp liquid supercharging in the Seal cage, after the heat exchange cooling, water flows directly into Seal cage, and mechanical seal is directly cooled off.High-temp liquid in the no pump chamber in the Seal cage has only the cooling water after the heat exchange cooling, and the mechanical seal cooling is abundant, has improved the cooling effect of mechanical seal, has prolonged mechanical seal working life.
2, increase venting blowdown mechanism after, can exit at any time by stop valve, discharge sewage in the Seal cage, improve mechanical seal working life; Can observe fluid temperature in the Seal cage at any time; This mechanism structure is simple, and is easy to operate.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
