Winter instrument maintenance

Abstract: the winter instrument maintenance information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. In winter, when the measured medium by measuring the pipeline for a transmitter, often appear frozen occurs, when the environment temperature is too low, the phenomenon such as coagulation, precipitation crystallization, seismic pressure gauge used instrument by environmental temperature is too low and beyond the normal operating temperature range. More flow meter manufacturers choose model price quote you are welcome to inquire, here is winter instruments article details of maintenance and administration. In winter, when the measured medium by measuring the pipeline for a transmitter, often appear frozen occurs, when the environment temperature is too low, the phenomenon such as coagulation, precipitation crystallization, seismic pressure gauge used by environmental temperature is too low and is beyond the normal working temperature range, directly affect the instrument shows that the accuracy of measurement. So we must to pipeline anti-freezing processing, instrument and meter need thermal insulation main objects are installed in the instrument insulation in the transmitter, the buoy type liquid level transmitter or other form of outdoor installation of water transmitting unit, pressure, differential pressure, flow rate instrument, such as the detection of pipeline and measuring line. Through the selection or other ways to avoid such accidents. Measures usually have: selection, heat preservation heat tracing, maintenance ( Point inspection, sewage) And so on. One, the selection of measures with insulation device type instrument. Differential pressure transmitter according to the category of the instrument use and installation location, proposed the instrument insulation antifreeze requirements, submit again with manufacturer to deal with. And select heat preservation heat tracing, maintenance ( Point inspection, sewage) Methods such as antifreeze solution. 2 with insulation heat preservation, heat preservation measures, with thermal insulation material will be the part of the instrument easy frozen or afraid of frozen wrapped up. Winter comes to check, often drainage, packing heat preservation material against breakage. 3, 1, steam heating heating measures measures which use pipe steam heating insulation. Winter heating to check before send steam steam heat pipe was clear or blocked. Zui good steam is 24 hours, don't be too hot, sometimes according to the weather temperature changes to adjust for the steam heat preservation rate, in order to prevent the temperature is too high to make transmitter led condensate vaporization pressure tube transmitter work or because of the low temperature transmitter led tube condensing surface frozen influence work flow transmitter. 2, insulation protection measures, a thermal insulation box, electric heating tube by three parts, such as enclosure, heater, instrument bracket, the structure form and protection case is the same, the difference is in the box is equipped with electric heating device, the structure as shown in figure, electric heating device is composed of electric heat pipe, temperature controller, body side with socket, when switched on, the heat in the oven to the required temperature, then by the temperature controller connected to the power supply continues to heat up. Through repeated work to keep the temperature in the cabinet can be within a certain range. B, steam pipe thermal insulation box, with heat pipe is made from metal tube S type structure. Casing wear plate and welding type joint and heat pipe welding and become, with heat pipe installed on the box as the top down out, through steam within the lumen of the heating cycle to achieve. With heat pipe materials generally fall into two kinds, namely copper pipe, seamless steel pipe ( Carbon steel) 。 C, as the key instrument box to add a layer of heat preservation cotton, at the gate of the incubator and in and out of the pipe mouth add glue sealing, insulation anti-freezing effect can reach the instrument system. 3, electric heating zone measures electric thermal insulation technology is a new type of the electrical energy directly into heat energy heating technology. Adding insulation cable, will accompany the tropics, winding on the instrument, or sticking to the instrument ark inside ( Used with the length of the tropical, but must pay attention to economic moderate) 。 Are applicable for pipe, valves, seismic pressure gauge, differential pressure transmitter of the pump body heat, antifreeze, and insulation or maintain the instrument temperature of single-phase constant power electric heating pipeline technology, the unit length of calorific value is constant, the output power is not affected by environmental temperature change and change, use is proportional to the length and the power, can arbitrarily splicing when installed, but must keep have a fever, At least 2. 5米) , outer woven layer with heat transfer and heat dissipation effect, and can be used as antistatic safety grounding. Mainly used for all kinds of pipes, the frost, heat preservation, zui to maintain high temperature 150 ℃. Note: strict in temperature control of liquid pipeline heat insulation ( With the temperature controller is required) 。 Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
