Magnetic level gauge It is widely used for medium level measurement of various tower, tank, tank, spherical vessel, boiler and other equipment. In complex environment, it is more necessary to pay attention to the daily maintenance of magnetic flap level gauge to prevent long-term operation and reduce the performance and life of magnetic flap level gauge.
1、 Open the bottom flange and install the magnetic float. The heavy end is magnetic and the end is upward. It can not be installed upside down.
2、 During commissioning, the upper pilot valve shall be opened first, and then the lower valve shall be opened slowly, so that the medium can enter the main pipe smoothly (the medium shall not impact the float rapidly during operation, which will cause dramatic fluctuation of the float and affect the display accuracy). Then, observe whether the magnetic red and white balls turn over normally. Then, close the valve of the lower lead pipe and open the blowdown valve to let the liquid level in the main pipe drop. Operate according to this method After three times, if it is normal, it can be put into operation (except for corrosive and other special liquids).
3、 According to the medium condition, the main pipe should be cleaned irregularly to remove impurities.
4、 If the length is more than a certain length (ordinary type > 3 rice , anticorrosive type > 2 rice ）In order to increase the strength and overcome its own weight, the middle reinforced flange or lug should be added as fixed support.
5、 The installation position should be kept away from or away from the inlet and outlet of the material medium, so as to avoid the rapid change of the local area of the material fluid and affect the accuracy of the liquid level measurement.
6 Magnetic level gauge No magnetic material is allowed to get close to the body. It is forbidden to fix it with iron wire. Otherwise, the normal operation of the magnetic flap level gauge will be affected.
7、 If the user uses the heat tracing pipeline by himself, the non magnetic material, such as copper pipe, must be selected. The heat tracing temperature is determined according to the medium condition.
8、 The installation must be vertical. The ball valve should be installed between the magnetic flap liquid level gauge and the vessel lead pipe to facilitate maintenance and cleaning.
9、 The medium should not contain solid impurities or magnetic materials, so as to avoid jamming the float.
10、 Before use, the small balls below the zero position should be set red with the correction magnetic steel, and the other balls should be white.
