The compressed gas vortex flowmeter is a new type of flowmeter that measures the flow of a closed pipe in accordance with the Karmen vortex principle. Because of its good media adaptability, it can directly measure the volumetric flow rate of steam, air, gas, water, and liquid without temperature and pressure compensation. With temperature and pressure sensors, it can measure standard volume flow and mass flow, which is throttling. Ideal alternative to flowmeters. The analysis and elimination of the failure of the compressed gas vortex flowmeter is as follows: 1. When the compressed gas vortex flowmeter has no signal output or the instantaneous flow rate is not displayed, the fault analysis and exclusion are as follows: 1) First check that the power supply voltage is correct. 2) If the power supply voltage is correct, turn the sensitivity potentiometer and amplification potentiometer counterclockwise. 3) If there is signal output, check whether the pipeline flow exceeds the measurable flow range of vortex street. 4) If the flow rate is within the measurable range, it indicates that the sensitivity of the vortex sensor flow sensor head is already low, and the sensitivity needs to be readjusted. 2. When the compressed gas vortex flowmeter has no flow in the pipe when there is signal output or instantaneous flow rate, the analysis and troubleshooting are as follows: 1) First check and confirm that there is no fluid flow or disturbance in the pipe and the pipe vibration intensity is too large. 2) Adjust the sensitivity potentiometer clockwise until no signal is output or instantaneous flow returns to zero. When adjusting the potentiometer, it should be as slow as possible. When adjusting the angle of 5 degrees, it should be paused for more than 10 seconds to observe whether the output is zeroing. 3. When the signal output of the electromagnetic flow sensor is unstable or the instantaneous flow rate is unstable, the fault analysis and troubleshooting are as follows: 1) First check whether the pipeline flow exceeds the measurable flow range of the vortex street. 2) If the flow rate is in the measurable range, check whether the straight pipe section meets the requirements before and after. If it is not qualified, the straight pipe section must be modified. 3) Confirm whether the process flow is a steady flow. 4) Check if the pipe vibration intensity is too large. If it is too large, it needs to install damping section. Disperse Dyes Printing Thickener

Disperse dye Printing Thickener as the main additive in the chemical printing industry, because of its excellent thickening, has already appeared in people's field of vision early, its true face is a rheological additive, can be no exaggeration It is said that it only needs to add a small amount of thickener to make it play a big role. Is its advantage only reflected in this amount? No, let me introduce you to the specific advantages of disperse dye printing thickeners.
1. After the consistency of the raw liquid product is increased, the raw liquid is better penetrated into the textile and uniformly sizing.
2. Provide good rheological properties for dyes or pigments, so that they are evenly distributed during printing without splashing and sagging.
3. Better penetration of the dye into the textile, combined with the fibers to form a well-defined, well-defined textile print.
4. The consistency is increased, so that the dye in the printing is fixed, and the reaction product and the residue are more conveniently and easily washed away.
Disperse dye printing thickeners are widely used in the thickening of textile printing and dyeing, coatings, printing and dyeing, sanding cloth, cotton cloth, chemical fiber cloth and other systems.
