Sewage electromagnetic flowmeter must be used continuously online, it is almost impossible to dismantle and transport it to the National Measurement Center for verification. Therefore, it is necessary to verify the accuracy of large-diameter electromagnetic flowmeters used in the field. The verific

First, the centrifugal pump to stop running after the request 1, centrifugal pump should stop running after the pump population valve, to be cooled and then turn off the auxiliary system valves. 2, high-temperature pump parking should be implemented according to the provisions of technical docum

According to the actual cable engineering data, the voltage rating of the variable frequency cable laid in this way is almost under 1.8/3kv, and this voltage level of the frequency conversion cable does not require phase-shielding, so we can use industrial adhesive in its When the cable is attached

The working principle of the bearing heater is to use the metal to generate eddy currents in the alternating magnetic field and cause itself to generate heat. The bearing heater is usually used in the heat treatment of metals and the like. The principle is that when a thick metal is in an alternati
