1. What are the hazards of not connecting the jumper wire of the coal powder scale?

It affects the operation of the scale at high flow rates.. If the jumper wire of the coal powder scale is not connected, it will affect the early operation of the scale during high flow rate. The full name of the coal powder measuring scale is "Circular Balance Flow Meter Weighing Machine", which is a high-precision powder flow meter weighing device jointly developed by Beijing Yanshan Powder Research Precision Machinery Co., Ltd. and Japan.

2. What are the applicable working conditions for a 700mm V-cone flowmeter?

The applicable working conditions for a 700mm caliber V-cone flowmeter can be divided into two categories: general industrial working conditions and special working conditions. The core is suitable for fluid measurement scenarios with high flow rate, high viscosity, and multiple impurities.

Universal family standard operating conditions - Measurement medium is clean liquid: such as clean water, thermal oil, softened water and other low impurity single-phase fluids, suitable for temperature range of -40 ℃~400 ℃, pressure up to 42MPa - Measurement of clean gas: including compressed air, natural gas, nitrogen and other gas media without particulate impurities - Measurement of saturated/superheated steam: steam operating conditions in accordance with GB/T 21446 standard, suitable for high flow rate steam measurement 2 Special adaptation conditions - High viscosity fluids: such as crude oil, asphalt, heavy oil and other media with a kinematic viscosity of up to 10000mPa · s, the V-cone cone cone structure can reduce fluid wall hanging and sedimentation - Impurity containing fluids: Sewage, mud, co

al powder conveying fluids containing a small amount of solid particles (≤ 10% volume ratio), as well as industrial wastewater with a small amount of oil pollution - Large pipe diameter and wide range working bucket conditions: 700mm diameter, suitable for industrial main pipelines with an inner diameter of 650-750mm, with a range ratio of up to 10:1, can cover extremely low flow rates (minimum 0.1m/s) to ultra-high flow rates (maximum 10m/s for liquids and 100m/s for gases) scenarios - High temperature and high pressure conditions: Suitable for high-temperature flue gas and high pressure in metallurgy and thermal power industries. Boiler feedwater measurement scenario 3 Not applicable to working conditions - fluids containing strong corrosiveness and no matching lining material, such as concentrated hydrochloric acid without anti-corrosion treatment - fluids containing a large amount of fiber impurities, such as white water from paper mills, are prone to entanglement before and after the cone, causing measurement deviation - pulsating flow is extremely unstable and has no damping buffer, such as the outlet direct pipeline of a piston compressor

3. Range parameters of solid dust flowmeter

The range parameters of solid dust flowmeter need to be determined according to specific working conditions and instrument types, and the common range is between 0-500 kg/h and 0-200 t/h. 1. The selection of core selection parameters for dust flow meters goes far beyond the range, and the following core parameters need to be matched: • Pipeline size: DN50 to DN500 is a common range, which directly affects the upper limit of flow. Coarseness of dust special sales segment: medium name, particle size distribution, humidity, t
