Wherein, ceramic layer generates the method for FRP is outward traditional glass fibre reinforced plastics lamination process.
A kind of modified node method of pump, it is characterized in that: on the position of high-pressure service pump conveying liquid, all adopt double layer construction, comprise the ceramic layer being positioned at inner side and the frp layer being positioned at outside, wherein, ceramic layer thickness is 5-100mm, and frp layer thickness is 5-20mm, this ceramic layer, for using unsaturated polyester resin, forms through the constant voltage infiltrations of at least 4 hours and solidification.
Seen from the above description, the invention provides a kind of manufacture method of pump modified node method,
1, in the FRP material that the skin of ceramicpump core, spool, runner is lining with, pottery itself has very strong corrosion resistance, but enbrittle, the present invention acid resistant alkali resin with the mode of high-pressure osmosis penetrate into pottery hole in go, isothermal curing again, again at its external sheath one deck 5-20mm glass fibre reinforced plastics, find that it can overcome the shortcoming of the high pressure fragility of ceramic material effectively.
2, after ceramic post sintering, there is tiny hole ceramic inside, and in order to make its water tightness better, mechanical strength is higher.Acid resistant alkali resin penetrates in the hole of pottery in the mode of high-pressure osmosis and goes, and can solve the intrinsic hard defects of pottery like this.
Experiment proves that the pump of structure of the present invention can at the pressure of 3Mpa-5Mpa, and fluid is the hydrochloric acid of 25% concentration, and temperature is effectively run under the operating mode of 40 DEG C.Meet high pressure resistant and corrosion resistant requirement simultaneously.
