Cold winter V cone flowmeter how to ‘keep warm’?

Case introduction

　　In the winter operation, V cone flowmeter is easily affected by the temperature, and even sometimes lead to it ‘strike’, then the maintenance of V cone flowmeter is particularly important. We mainly from what aspects to make our V cone flowmeter can be in the cold winter ‘keep warm’, so as to ensure normal operation? 

　　First, electric heating insulation

　　Electric heating insulation is a new form of heating by the direct conversion of electrical energy into heat form of heating, retrofitted with insulation cable, will be accompanied by tropical wrapped around the flowmeter on the exterior, or sticking in the appearance of the cabinet interior. This kind of heat preservation not only only in the V cone flowmeter heat preservation on the use of the same applies to the pipeline, valves, shock-resistant pressure gauge, differential pressure transmitter pump body accompanied by heat, anti-freezing and heat preservation.

　　There is another kind of goods on the market, is the soft packing electric accompanies the heat to maintain the sleeve, specially uses in the space is narrower the instrument to accompany the heat, the explosion-proof, the primary device in the appearance of the introduction of the pressure pipe section and the valve.

　　Second, heat preservation maintenance box

　　(a) we can add a layer of heat preservation cotton on the V cone flowmeter equipment, in the heat preservation box door and in and out of the pipeline mouth with rubber sealing, can achieve the effect of better heat preservation and anti-freezing of the appearance of the system.

　　(b) The steam pipe accompanies the heat preservation box, accompanies the heat pipe is with the metal pipe to make the S-type layout, the box body upper and lower selects the welded through the plate joint and accompanies the heat pipe to weld and become, accompanies the heat pipe to install in the box for the upper into the lower out, through the vapour in the pipe cavity of the cycle and achieves the intention of heating. Accompanied by the heat pipe is usually divided into two kinds, namely the purple copper tube and the seamless steel tube.

　　(c) The electric heat pipe accompanies the heat preservation box, by the box body, the heater, the bracket and so on three parts of the composition, its layout and the maintenance box the same way, the difference is that the box is equipped with electrical heating equipment. Electric heating equipment is composed of electric heaters and temperature controllers, box side surface equipped with sockets, when the power supply is connected, the box is heated to the required temperature, and then by the temperature controller connected to the power supply to continue to warm up, after repeated operations to make the box temperature is maintained within a certain range.

　　Through the above several methods will certainly give us the V cone flowmeter warming work to bring great help, only it can work properly, then to better serve us, serve the public!
