Electromagnetic flowmeter products can be widely used in chemical industry, steel, coal, mining, petroleum exploration, petrochemical, papermaking, environmental protection, sugar, pharmaceuticals, food, water conservancy irrigation, water supply and drainage, and port dredging. Electromagnetic flowmeters are especially used in various fields. There are unique advantages in the measurement of various types of slurry fluids, which can safely measure various acids, alkalis, salt solutions, raw water, cooling water, sewage, coal slurry, ore slurry, mud, cement slurry, paper pulp, syrup, coal water slurry , Corn steep liquor, fiber pulp, grain pulp, lime milk, hydrogen peroxide, beer, wort, black liquor, green liquor and various beverages and other conductive fluids and solid-liquid two-phase volume flow. In the measurement process, as the part of the electromagnetic flowmeter to pick up the flow signal, the electrode is in direct contact with the measuring medium, so it is easy to adhere to dirt on its surface, which affects the measurement. In order to ensure the accuracy of the measurement, the electrode surface needs to be cleaned regularly. In the traditional electromagnetic flowmeter, the electrode is fixed on the measuring tube, and the shell is closed. If the surface of the electrode is to be cleaned, the flowmeter must be disassembled from the pipeline, which is laborious and laborious and affects industrial measurement. However, if the electrode is designed to be easily disassembled and fixed, it is necessary to solve the technical problem of how to firmly fix the electrode under the premise of ensuring that it is easy to disassemble.
An electromagnetic flowmeter with detachable electrodes. It consists of a casing, a measuring tube installed in the casing, a measuring tube lining, and an electrode assembly. The electrode assembly consists of an electrode shaft and an electrode tip, an electrode holder and an insulated electrode holder installed on the electrode shaft. The sleeve is composed of a boss, the boss is provided with a central hole and a gland is provided; a knob is provided at the end of the electrode shaft, and a compression nut and a compression nut are screwed on the electrode shaft. The insulating seat cover is provided with a spring between the insulating seat cover and the knob.
The new type adopts this structure, and the spring arranged between the insulating seat cover and the knob makes the installation of the electrode head more stable through the supporting force of the insulating seat cover. When the electrode needs to be cleaned, open the gland and operate the knob through the center hole to rotate it back, thereby driving the electrode shaft to rotate, and the electrode head is taken out from the center hole and cleaned. After cleaning, it is still installed to the original position through the center hole, that is, a cleaning job is completed. Since the electrode cleaning problem can be solved conveniently, the measurement accuracy of the electromagnetic flowmeter can be effectively guaranteed.
