Method for reducing sealing temperature of centrifugal pump

Reduce the centrifugal pump sealing temperature is to improve the work efficiency and the service life of the centrifugal pump only measures, how to effectively reduce the sealing temperature of centrifugal pump, we look at here is how to express the.
Sealing structure of centrifugal pump
1, single face seal of centrifugal pump: the injection type flushing, flushing line is about 100 degrees less liquid wax, high pressure ratio sealing cavity 0.05~0.15Mpa. The gland with hot water (water quench). General can use a cycle (ten months).
2, centrifugal pump metal bellows seal: compact structure, easy to install, in the case of the same auxiliary system, the life of the ordinary seal 2~3 times.
3, centrifugal pump double end face machine: the use of circular flushing, plus external cooling, life is 1.5~2 times the single end face.
4, centrifugal pump friction pairs of hard to hard (SiC/SiC, YG6/YG8, etc.), high viscosity, containing a small amount of solid particles of the medium or have a crystal produced medium, has a very good effect.
Two, the cooling form of centrifugal pump:
1, domestic centrifugal pump set of cooling water in the seal cavity around the cooling with cold water, which makes the seal cavity temperature down to 200~250 DEG C.
2, the single seal, using the injection washing, cleaning, leading from the outside temperature is about 100 DEG C oil (diesel diesel is generally not, because the product, not only reduces the temperature), and improve the working environment, is the effective way to.
3, the gland with chilled water; in addition to lower temperature, also can prevent water pipeline blockage.
In the actual operation, in accordance with the above requirements and then combined with the actual working environment to effectively carry out the centrifugal pump seal temperature reduction.
Welpump will be the spirit of "quality first, technology first, customer first, honesty first" principle, for domestic and foreign companies to provide advanced technology services and high-quality products.
