Abstract
The utility model relates to a metal-ceramic combined wear pump case, which has a metal pump case. The inner wall of the pump case is lined with a ceramic wear resistant layer. The utility model has the characteristics of favorable wear resistance, long service life, rare and expensive metals saving, etc. If the ceramic wear resistant layer is eroded and worn, the metal-ceramic combined wear pump case can be repeatedly used after the ceramic wear resistant layer is exchanged. The utility model is suitable for various slurry pumps.
Description
The utility model relates to the pump case of a kind of pump case, particularly slurry pump.
What slurry pump aspirated is the fluid that solid and liquid mix, so in the high speed rotating of impeller, the inside pump casing pumping chamber suffers serious erosive wear, directly influences the working life of pump case.For addressing this problem, common way be adopt wear resistance preferably chromium system or chrome-nickel material cast pump case, though this alloy pump case can increase the service life effectively, this class alloy material costs an arm and a leg, casting technique is also complicated.
The purpose of this utility model is that a kind of improved ceramet complex abrasion-proof pump case will be provided, and it can strengthen the wear resistance of pump case effectively, prolongs its working life.
The purpose of this utility model is achieved in that the interior wall liner one ceramic scuff-resistant coating at the metal pump case, isolated the not direct erosion metal pump case of fluid-mixing like this, and stupalith itself also has wear resistance preferably, thereby guarantees to prolong effectively the working life of pump case.
The utility model because only need be in the virgin metal pump case wall liner one deck stupalith, so structure is simple especially; Simultaneously, because ceramic scuff-resistant coating is compounded on the metal pump case, in case by erosive wear, only need to change ceramic scuff-resistant coating, its metal pump case is still reusable, and to now worn out also Pasting reparation of useless pump.
Fig. 1 is a generalized section of the present utility model.
Do further describing of embodiment below in conjunction with accompanying drawing: this pump case has a metal pump case (1), and wall liner has ceramic scuff-resistant coating (2) within it, and ceramic scuff-resistant coating can adopt some blocks of ceramic plates to combine.The width of every block of ceramic plate should be similar to pump case negative camber arc length, with special binders ceramic plate is pieced together at metal pump case internal surface, and scuff-resistant coating can adopt also that ceramic particle is bonding to form.Ceramic plate and ceramic particle adopt silicon nitride or silicon carbide or alumina sintering to form, and the utility model is put into practice, and is respond well.
Claims (4)
1, a kind of ceramet complex abrasion-proof pump case, this pump case has a metal pump case (1), it is characterized in that metal pump case inwall is lined with ceramic scuff-resistant coating (2).
2, pump case as claimed in claim 1 is characterized in that ceramic scuff-resistant coating (2) is combined by some blocks of ceramic plates.
3, pump case as claimed in claim 1 is characterized in that ceramic scuff-resistant coating (2) is formed by the ceramic particle bonding.
4,, it is characterized in that described ceramic plate and ceramic particle adopt silicon nitride or silicon carbide or aluminium oxide to make as claim 2 or 3 described pump cases.
