Rotor blade is mainly used for crushing hot sinter at 700~800℃ at the end of sintering machine. In order to extend the service life of single tooth roller, our company has chosen the method of reforming the metal composition at the worn part of single tooth roller. Chromium carbide overlay composite surface is adopted, and wear-resistant materials are added to the wear-resistant parts. The wear resistant alloy is welded in the worn part by surfacing repair.

Points to note include:
First, after installing the liquid turbine flowmeter, be sure to really study the liquid turbine flowmeter instructions. For the problems encountered in the initial operation, be good at analyzing and thinking. The entire set of liquid turbine flowmeters has been calibrated and calibrated on the flow calibration device of the manufacturer. As long as the matching numbers of sensors and converters and the meter coefficients are correct, general liquid turbine flowmeters can be put into operation without any adjustment.
Second, before the instrument is put into operation, the liquid turbine flowmeter sensor must be filled with the actual measuring medium, and after the power is turned on, the zero point is adjusted in the static state. After operation, check the zero point according to the medium and the conditions of use. Check the zero point regularly, especially for the easy-to-precipitate, easily polluted electrode and non-clean medium containing solids. In the initial stage of operation, you should check more to obtain experience and determine the normal inspection cycle.
Third, if the contact resistance of the two electrodes changes, it indicates that the liquid turbine flowmeter electrode is likely to be contaminated; the contact resistance becomes larger, the contaminant may be an insulating deposit; the contact resistance becomes smaller and may contaminate The object is a conductive deposit; the contact resistance of the two electrodes is asymmetrical, indicating that the two electrodes are not contaminated to the same degree; the drop in the insulation resistance of the electrodes and the excitation coil indicates the degree to which the liquid turbine flowmeter sensor is damped; when the insulation resistance drops to a certain degree The degree will affect the normal operation of the instrument.
Turbine flowmeter is widely used to measure the corrosive effect of stainless steel and cemented carbide in closed pipelines, and there are no impurities such as fibers and particles. The fluid has a kinematic viscosity of less than 5×10-6m2/s at the working temperature, and the kinematic viscosity is greater than 5 ×10-6m2/s liquid can be used after the solid-liquid calibration of the flowmeter, as well as quantitative control, over-alarm, etc. It is an ideal meter for flow measurement and energy saving.
