Liquid flow meters, including ceramic detectors, thermal conductivity testers, dilatometers, material testing instruments, elastic modulus meters, etc., are instruments used to detect, measure, observe, and calculate various physical quantities, material compositions, physical properties, etc. Or equipment.
The flow meter maintenance steps are:
First, the liquid flow meter external wipe steps:
1. Wipe the liquid flow meter with a dry fine cloth or wiping paper first to wipe off the dust or oil, etc. Be careful not to injure the appearance of the instrument.
2. Use clean, dry cotton cloth with industrial alcohol to wipe the appearance of the instrument, especially metal and non-metal surfaces.
Second, the liquid flowmeter mirror wipe steps:
1. Gently wipe the mirror surface with lens paper. Do not use force to avoid damaging the mirror surface.
2. Use a cotton swab dipped in industrial alcohol to gently wipe the surface of the mirror, and wait for the alcohol to evaporate before installing it.
3. The mirror wipe can be divided into a calibration glass lens and a lens lens group. Since the dust particles will cause the black spots of the image, it is important that the mirror surface is wiped. After the device is cleaned, the wipe result must be observed again.
Third, the liquid flow meter granite surface cleaning steps:
1. Wipe the surface of the granite with a dry fine cloth or a wiping paper to wipe off the dirt or grease left by the machine after the measurement.
2. Clean the outer surface of the granite with a clean, dry cotton cloth and wipe it with industrial alcohol. The volatilization of the alcohol will naturally evaporate.
3. If necessary, use granite special maintenance oil and then wipe.
Fourth, the liquid flow meter transmission part: the dry friction part and the lubrication part, dry friction part of the air bearing and the toothless screw transmission mechanism of the distinction.
Dry friction part of the maintenance steps:
1. Wipe the surface with a dry cloth or wiping paper to wipe off dust or oil.
2. Blowers can also be used to blow off dust.
3. When necessary, use a clean, dry cotton cloth with industrial alcohol or high-grade lubricant to wipe the surface.
Liquid Meter Lubrication Section Maintenance Steps:
1. First wipe the dust with a fine cotton cloth.
2. Lubricate part of the liquid flow meter and add lube oil or add it by grease gun.
Classfication for the sound barrier wall: Base on the application environment: the traffic noise barriers, equipment noise attenuation noise barriers, factory noise barriers; Base on the material: metal noise barriers,concrete noise barriers, PC noise barriers,etc; Base on different application: rail noise barriers, highway noise barriers,urban landscope noise barriers,redetial area noise reduction noise barriers.
Structure of the sound barrier: Sound barriers are made of the steel H beam and Sound Absorbing Panels. Steel H beam is the main force components, it si fixed by bolts or welding on the road barrier wall or the side of the embeded steel plate. Sound absorbing panel are the main noise reduction component,it is ixed by high stength spring clip on the groove of the beam. Considering the environment the highway, railway road and subway, it is designed for open-air corrosion, easy transportation and installation, and long life.
Height of the sound barriers is also bettween 1m-5m. Covering the effective area, the noise reduction is 10-15dB(A)(125HZ-40000HZ,1/3 octave),up to 20dB(A).Generally the sound barriers height and distance is more bigger, the reduction effect is more better.
1. Good perfomance of acoustic insulation: the average acoustic insulation amound should not less than 35dB;
2. High sound absorption coeficient: the average sound absorption coeficient amount should not be less than 0.84.
The metal Sound Barrier Wall accoding to diffirent hole shape,there also are two types:
1.Window-blinds Types
2.Round shape types
