Zirconium oxide ceramic offers much stronger mechanism strength, fracture toughness than other fine ceramic material, it is well suited to replacing metals due to its these exceptional features.Besides, zriconia has far highest resistance to chemicals and superior erosion resistance, This material is very fit to build wear parts ,cutting tools in every harsh environment.In the meantime, very low thermal conductivity is other critical characteristics of zirconia, it's a very ideal material in need of low thermal conductivity field.
Yttria partially stabilized zirconia(Y-TZP), Magnesia partially stabilized zirconia (M-PSZ) as two regular material exist there for variety of zirconia ceramic components' production.
Zirconia ceramic components typically works as structural ceramics, wear parts, cutting tools, precision valve seats and seals, pump pistons,pump sleeves, spray nozzles, ceramic bearings, fiber optical capillary, oxygen sensors and so on.

(2) When the indicated value of the flow control instrument system reaches the maximum, the detection instrument will often indicate the maximum value. At this point you can manually control the valve to open large or close small, if the flow can be reduced is generally caused by the process operation. If the flow rate does not fall, it is the cause of the instrument system. Check whether the regulating valve of the flow control instrumentation system is active. Check whether the instrument measures the pressure eliciting system. Check whether the instrument signal transmission system is normal.
(3) The flow control instrumentation system indicates that the value fluctuates more frequently. The control can be changed to manual. If the fluctuation is reduced, it is the cause of the instrument or the instrument control parameter PID is not appropriate. If the fluctuation is still frequent, it is the process operation. Caused by.
(1) When the indicated value of the flow control instrumentation system reaches the minimum, the on-site inspection instrument is first checked, and if it is normal, the failure is displayed on the instrument. When the on-site detection instrument indicator is also the smallest, check the opening degree of the regulating valve. If the opening degree of the regulating valve is zero, it is often a fault between the regulating valve and the regulator. When the on-site detection instrument indicates the minimum and the opening of the regulating valve is normal, the cause of the failure is likely to be caused by insufficient system pressure, blocked system piping, insufficient pump volume, crystallization of the medium, and improper operation. If the instrument is faulty, the reasons are: the orifice differential pressure flowmeter may be a positive pressure induction conduit plug; the differential pressure transmitter positive pressure chamber leakage; the mechanical flowmeter is a gear stuck or a filter plug.
