Describe the new technology of hearing aid - Bluetooth Style

Hearing Amplifier Bluetooth technology has been launched by manufacturers 3 or 4 years ago. Due to the lack of understanding of the majority of users and the high price of relevant products, few of them are used. With the introduction of hearing aids with Bluetooth technology by various manufacturers in the past year or two, the price of hearing aids with this technology has been reduced to a level acceptable to a considerable number of customers, and the number of users has gradually increased. In the past, ordinary hearing aids did not work well when answering telephone calls, for two main reasons:

One is that the voice of the telephone needs to be transmitted through air to the microphone of the hearing aid. Because when a user makes a phone call, the receiver and the microphone of the hearing aid are always not very accurate, which causes the sound signal attenuation of the phone. Even though some hearing aids use inductance, the sound energy transmitted to the hearing aid is incomplete because the distance and the electromagnetic energy of the telephone are not enough.

Second, when making a phone call, the receiver of the phone can only be placed next to the microphone of one ear. At the same time, the microphone of the hearing aid can receive the sound made by the user around, resulting in poor signal and noise when making a phone call. For these reasons, a significant number of users are less effective at making phone calls with hearing aids, and some are even less clear than without them.

The combination of hearing aid and Bluetooth technology solves the problem well.

Hearing aids with Bluetooth technology do not require the user to move the phone's receiver to the microphone of the hearing aid. There is a wireless receiving module in the hearing aid, and a module (with Bluetooth signal reception and common wireless signal transmission functions) is added outside the hearing aid. This module is the same size as the matchbox (different brands have slightly different sizes), or it is hung on the chest or in the pocket. The main function of the module is to receive the Bluetooth signal from the end of the phone and transmit the audio information of the signal directly to the binaural hearing aid. This process has several advantages, which completely overcome the defects of the above mentioned SNR and inaccurate position. First, the sound in the telephone is transmitted wirelessly to the user's hearing aid with almost no loss, ensuring that the sound energy does not decrease.

The second is that he can direct the voice from the phone to the user's two hearing aids, so that both ears can hear the voice of the other person inside the phone; In most cases, the speech recognition rate of binaural listening is much higher than that of monaural listening. The third point is that in the Bluetooth mode and the ordinary wireless transmission process, the voice in the phone is equivalent to directly into the hearing aid, without any noise interference in the environment of the phone receiver, which greatly improves the signal-to-noise ratio. Based on the above three points, Bluetooth Style Hearing Amplifier has made a lot of changes in the effect of telephone answering, which has been praised by many users.

MFI Magnetic flux leakage test refers to the formation of a leakage magnetic field on the surface of a test piece after it is magnetized due to defects on the surface or near-surface of the test piece. People can detect defects by detecting changes in the leakage magnetic field.

Briefly describe the limitations of the magnetic flux leakage detection method.

The limitations of the magnetic testing equipment are as follows:

1. It is only applicable to ferromagnetic materials.  
2. Detection sensitivity is low.
3. The quantification of defects is rough.  
4. Due to the shape of the workpiece to be inspected, the leakage magnetic field method is not suitable for detecting test pieces with complicated shapes because the sensor detects the leakage flux.  
5. Magnetic flux leakage is not suitable for cracking very narrow cracks, especially closed cracks. It was found in the experiment that cracks with very narrow cracks, magnetic particle flaw detection and magnetic flux leakage inspection failed to produce an indication of injury and injury.

Briefly describe the application range of magnetic flux leakage detection technology.

1. The application of magnetic flux leakage detection in the steel industry: in steel mills, it is mainly used for inspection of steel structural parts, billets, round bars, bars, steel pipes, welds and steel cables. Make sure the finished product is in good condition. On many occasions, users will not receive steel products that have not been inspected by steel mills and third parties.  Users often use non destructivetesting equipment before manufacturing, which ensures the manufacturer's technical requirements for the product. Such inspections are often carried out by an independent inspection company or the user's quality assurance department.  
2. The application of magnetic flux leakage detection in the petrochemical industry: the installation of oil and gas pipelines (including buried pipelines), storage tank floor or the recovery of oilfield steel pipes.  
3. Other applications: regular in-service inspection of used steel cables, wire ropes, and chains.

BKN's benchtop magnetic flux leakage testing equipment are capable of detecting workpieces efficiently and accurately.

If the time of hf welding pvc is too long, there are often some faults. After the failure occurs, users must find and deal with it in the first time and solve it in time. For different faults, the solutions are different. The following solutions are listed here for everyone:

If the welding effect is not ideal or it cannot be welded or the workpiece is damaged when it is in the process of hf welding pvc, we can not think that it is the problem of equipment. It could be other problems. For example: equipment setting error, blown fuse and so on may happen.

Common failure analysis and solutions:

1. If there are bubbles in the process of hf welding pvc with workpieces, it is not directly related to the equipment usually.

(1) situation of loose connection

it is possible that the flow meter of the gas regulator has been damaged or blocked with sundries.

(2) there may be sundries on the surface of the workpiece.

2. it is not directly related to the equipment if the voltage is unsteady in the process of hf weldingpvc with workpieces.

(1) loose connection wire between the main machine and the extension machine

(2) the induction coil is out of shape or there is no distance between the coil and the coil, or the induction coil is loose.

If above circumstance has been excluded, it still cannot work normally, users should turn off equipment and ask professional technicians to repair the equipment. If the device suddenly stops working in the process of use, you should immediately turn off the device and check the host, and wait for 3-5 minutes before starting up. If it can not work normally after turn it on, ask professional technicians to repair the equipment. But users also need to be skilled in using the equipment, and can make an accurate judgment of the corresponding fault to timely solve the fault, reduce the waste and loss of equipment and production.

Ceramic membranes (Porous Ceramic Membrane & tubular ceramic membrane) are available for microfiltration, ultrafiltration and nanofiltration as single-channel or multiple-channel elements with channel diameters between 2 and 16mm.

Contact us now for more details about China membrane and the ceramic membrane price!

The principle of porous tubular ceramic membrane

The principle of the filtration is based on two opposing effects: on the one hand, the particles are transported by the filtration flux to the membrane where they cause an increase in concentration; on the other hand, concentration differences are again reduced by the turbulence of the cross-flow and by Brownian motion of the particles. Ceramic membrane separation has greatly improved work efficiency and quality.  

During filtration by means of ceramic membranes made by JIUWU ceramic membrane manufacturer, the medium to be filtered flows through the channels of the membrane support. All particles whose size exceeds the pore radius of the membrane are retained. The particles /molecules build up in the concentrate. The filtrate permeates through the pores and depending on the procedure is subjected to subsequent process stages. This filtering method is also called "cross-flow filtration" or "dynamic filtration". Cross-flow management can achieve stable fluxes. Still, the cleaning of cross-flow installations needs to be applied from time to time. Cleaning is performed by means of backward flushing or chemical cleaning. There are various ceramic membranes for water treatment in the market, while JIUWU ceramic membranes for wastewater treatment perform very well.

We offer different kinds of composite insulator for substation. Contact us get more details about composite insulator, such as TDS, Application Method, OEM etc.

We can supply different type of composite silicone insulator, also customer required.

Composite insulator composite polymer insulator composite silicone insulators are a special type of insulation control that can play an important role in overhead transmission lines.

Composite insulators are also known as synthetic insulators, non-porcelain insulators, polymer insulators, rubber insulators, etc. The main structure is generally composed of a shed skirt, a FRP core rod and an end fitting. The shed skirt is generally made of organic synthetic materials, such as ethylene propylene rubber, high temperature vulcanized silicone rubber, etc.; FRP mandrels are generally made of glass fiber as a reinforcing material, and a oxidizing resin as a base material; The end fittings are generally carbon steel or carbon structural steel coated with hot zinc-aluminum.

Classification of Silicone Rubber Insulators silicone rubber insulator silicone composite insulators

Composite insulators can be divided into: line composite insulators and power stations, electrical composite insulators. It can also be divided into rod-shaped suspension composite insulators, pin-type composite insulators, cross-arm composite insulators, pillar composite insulators, wind-proof partial composite insulators, and so on.

Advantages of Composite Silicone Insulator

Small size, easy to maintain;

Light weight, easy to install;

High mechanical strength, not easy to break;

Excellent seismic performance and good stain resistance;

Fast production cycle and high quality stability.

End Fitting Structure

Composite insulators vary in their structure depending on the characteristics of use. In addition to meeting the tensile strength, meeting the requirements, and reliably connecting with the mandrel, the design of the metal tip also needs to meet the special requirements for application under high voltage. Composite insulators are generally made in the shape of a rod with a small capacitance. Therefore, the voltage distribution on the surface of the insulator is very uneven. Thus, in normal operation, the generated corona will be harmful, so it is necessary to use a pressure equalization measure. In addition, the synthetic insulating material cannot withstand an electric arc of several tens of kiloamperes. In the event of a short circuit fault, it will burn the umbrella near the wire and the tower, so arcing is required. At home and abroad, the method of adding a pressure equalizing ring is generally adopted to uniform the end electric field, weaken the corona, and lead to the fault arc.

The voltage equalizing ring of the composite insulator is a component of the composite insulator. Its function is to control the electric field strength inside the insulator, avoid internal partial discharge, reduce the local electric field strength of the external surface, especially the surface of the metal connecting part, and reduce the radio interference. Leading the power frequency arc to avoid burning the surface of the insulator and minimizing the local electric field strength near the end surface to improve its anti-smudge performance.
