How to make the flowmeter safe for the winter
1, steam heating measuresThat is the use of tube steam heating insulation. Before winter heat transfer, check that the steam insulation line is unblocked or blocked. The best steam is 24 hours pass, not too hot, sometimes according to the weather changes in temperature to adjust for the insulation of steam temperature is too high, in order to prevent the transmitter pressure in tube condensation liquid vaporization effect of transmitter or because the temperature is too low the transmitter pressure coolant condenser transmitter smooth effect.2, thermal insulation box measuresA, electric heat pipe heat insulation box, composed of three parts of body, heater, meter bracket, its structure and the same protection box, the box is equipped with electric heating device, when the power is turned on, the temperature required for the heating, the temperature controller is switched on to rise.B, the steam pipe heat insulation box with heat pipe is a S type structure with a metal box under control. Using welded joints and the wear plate with the heat pipe is welded with the heat pipe installation is in progress under the box, and achieve the purpose of heating by steam in the lumen of the cycle.3, electric heating belt measuresThe technology of electric heat tracing is a new heating technology, which directly transforms electric energy into heat energy. Install insulated cable, attach the tropics to the flowmeter, or stick to the inside of the flowmeter cabinet.Applicable to the pipeline, valve, pump body and heat insulation, anti freezing and temperature meter pipeline process or maintain Dan Xiangheng power band, the calorific value per unit length is constant, the output power is not affected by ambient temperature change, and power is proportional to the length of use, can be arbitrary splicing in the installation, but must have a the heating section (at least 2.5m).
Heat insulation material, that is, with heat preservation material will flow easily frozen or frozen parts. When winter comes, it is necessary to check and regularly discharge the sewage so as to prevent the breakage of the packing material
Belt type flowmeter. According to the type, purpose and location of the flowmeter, the heat preservation and anti freeze requirement of the flowmeter is presented and submitted to the manufacturer for processing.
