Dust collector bag is the heart of a bag filter and is generally called a filter dust bag, dust collection bag. The dust collector bag is a key part of the operation of the bag filter. Usually, the air filter bag is suspended vertically in the dust collector. It is a dust removal device that uses a bag filter element made of a fiber braid to trap solid particles in a dust-containing gas. The principle of action is that the dust particles are intercepted by the collision of the fibers with the inertial force of the filter cloth fibers.

The industrial dust collector bags is suitable for capturing fine, dry non-fibrous dust. The filter bag is made of textile filter cloth or non-woven felt. It uses the filtering action of the fiber fabric to filter the dust-laden gas. When the dust-laden gas enters the bag filter, the dust with large particles and large gravity settles due to gravity. When it falls down into the ash hopper and the gas containing fine dust passes through the filter, the dust is trapped and the gas is purified. Looking for dust bag manufacturer in China, Senotay is your best choice.

Are you wearing a mask and protecting yourself and keep social distance?

CXT 14 years Turnstile source factory in China, independent R&D capability,dedicating in design and manufacture high quality secured access control gateway.

How to protect yourself and the temperature measuring personnel at the front-line?

How to accurately screen and obtain temperature measurement data in real time?

In order to anti cross infection, CXT team dedicate in working out the integrated turnstile solutions and take actions in earlier stage, in which Temperature Measurement AI Face Terminal with be fixed on the Security Turnstiles to form a non-contact and efficient entrance control lanes in public sites (like hospital,schools,campus,office,hotel ,station etc),it also named as Fever Detector,Temperature Detector turnstile.

Why to adopt a unattended Temperature screening Entrance control?

In the process of temperature measurement, the opportunity for close contact between people is increased. The temperature measurement personnel is dangerous, and the measured person is also dangerous. If some of them are infected by the virus, cross infection is likely to occur.

On occasions with a large flow of people, the temperature measurement personnel take temperature one by one, the speed is slow, the efficiency is low, and the frequency of close contact with personnel is more.

By manual temperature measurement & handwritten record, the temperature data record is incomplete, the statistics, query and tracking are inconvenient. For example, if you want to query how many fever personnel there are in a certain period of time, it is difficult to obtain the required information in real time.

The terminal has three main parts: matching part, transition part and crimping part. The crimping part is the only part whose design is affected by the crimping process. Here are some of the most common problems and corrective actions.

1. Conductor crimping height is too small or too large

Solution: adjust the height of conductor crimping on the crimper. Use vernier calliper or micrometre to check whether the crimping height is within the specified range, and recheck according to the required frequency during the operation to maintain the correct crimping height.

2. The insulation crimping area is too small or too large

Most types of crimping tools can adjust the insulation crimp height. The correct adjustment allows the terminal to clamp the insulation at least 180 degrees without piercing the insulation. When the outer diameter of the insulating crimp of the terminal is close to the outer diameter of the cable insulation, the best method is IDT technology.

3. Loose core

Solution: fold up the cable again to form a bundle, and then insert it into the terminal for crimping. If the removal of the insulation from the cable is a separate operation, the cores may be inadvertently separated during handling or bunching. Use half stripping and keep the insulation removed so that the insulation is not completely removed from the cable until the terminal is ready to be crimped to the cable, which helps to minimize the core looseness.

4. Too short stripping length

The stripping length of the cable is too short, and the distance out of the front of the conductor crimping area cannot obtain the required outer diameter of the cable. The solution is simple: increase the stripping length of the stripping equipment to the specified value of the terminal.

5. The cable is inserted too deep

Solution: make sure that no excessive force is used to insert the cable into the crimper to make it over-voltage the cable stop of the crimper, or adjust the position of the cable stop to correctly position the stripped cable axially.

6. Over bending

Solution: adjust the position of the limit pin on the crimper. This pin is located in the crimper and contacts the joint area of the terminal when crimping the cable in the crimping area. During the crimping process, a large amount of metal at one end of the terminal (in the crimping area) moves. Such a large force tends to force the front of the terminal up unless limited by a suitable "limit pin."

7. Crimping too far forward

The reason for this problem is that the terminal and the metal strip (the metal strip connected by the terminal when you receive the goods from the manufacturer) are not in the correct position relative to the crimper. Just loosen the base plate of the interchangeable tool, and then realign the crimper to solve the problem.

8. Too small bell mouth

The correct size of the bell mouth is 2 times the thickness of the terminal material. In essence, it affects the performance of the terminal. If the bell mouth is missing or the thickness of the terminal material is less, there is a risk of cutting the wire core. Reduced core retention reduces termination strength. To correct the problem, make sure that the punch on the crimping device is correctly aligned with the base.

9. The bell mouth is too large

If the bell mouth is too large, the total contact area between the terminal crimping area and the cable will be reduced. The smaller the contact surface between the cable and the terminal, the smaller the cable drawing force. If the crimp height is correct, it may be caused by tool wear and should be replaced.

10. Tail material is too long

Solution: adjust the feeding plate on the crimper to make the terminal correctly centred in the crimper. Another sign that the terminals are not properly centred is that the bellmouth is not properly formed. This occurs because the bell mouth has a spatial relationship with the tool of the tailings.

11. Installation of an intelligent pressure management system

The intelligent pressure management system can monitor the operation of the terminal machine in real-time, find out the abnormal pressure in time, and adjust and maintain the equipment in time as described above! In this way, the machine has been in a good state of operation, thus indirectly reducing the production of defective products!

However, it should be noted that although the pressure management is very sensitive and can be used to evaluate the operation of the machine, in normal production, the tolerance is usually set to a large extent to reduce the number of alarms, so the various adverse conditions described above are basically impossible to detect all without leakage.

The intelligent pressure management system can detect 100% of the fatal problems such as all the core wires are cut off, all the glue is wrapped, and the terminals are deformed. These fatal problems cause great pressure changes. It is the main significance to prevent these fatal problems from flowing to customers!

Compared with the outer conductor, the inner conductor with a smaller size and lower strength is more likely to cause poor contact and lead to connector failure. Most of the inner conductors of the connector adopt elastic connection, such as spring claw type elastic connection, socket slotted type elastic connection, bellows-type elastic connection, etc. Among them, the socket slotted elastic connection has the advantages of simple structure, low processing cost, convenient assembly and the most extensive application.

1. The inner conductor is not fixed firmly

In order to assemble, the structure of many RF coaxial connectors is that the inner conductor is divided into two sections by the support of the medium and then connected with the thread. However, due to the small diameter of the inner conductor, the connection strength of the inner conductor is very poor, especially for some small RF coaxial connectors, if the screw connection is not fixed with glue. Therefore, when the connector is connected and disconnected for many times, under the long-term action of torsion and tension, the internal conductor thread may loosen and fall off, leading to connection failure.

One of the common structures of the RF coaxial connector is that the inner conductor, dielectric support and outer conductor are fixed together by adhesive. If the amount of glue applied is not enough or the connection strength of the glue is not enough during the assembly of this structure, the glue applied part may be broken due to the stress during the use, which will cause the inner conductor to rotate or move axially, the inner conductors cannot form good electrical contact, and the connection fails.

Improvement method: when the coaxial connector is assembled, the proper amount of conductive adhesive or thread locking agent can be applied to the threaded connection to increase the reliability of the threaded connection. The adhesive with high bonding strength shall be selected, and the glue shall be filled into the whole glueing hole during glueing; the knurling at the glueing place of the inner conductor shall be increased to increase the contact area between the inner conductor and the adhesive, so as to prevent the inner conductor from rotating; the radial dimensions and tolerances of the inner conductor, the outer conductor and the medium support shall be adjusted properly, so that the fit between the inner conductor and the medium support, the medium support and the outer conductor is interference. Fit also can make the three together more firmly.

2. The size of a socket or pin of the inner conductor is incorrect

If the hole diameter of the conductor in the jack is smaller than the specified size, when the pin of the conductor in the pin enters the jack, it will cause the jack to expand excessively, and the shape variable will exceed its elastic deformation range, resulting in plastic deformation, resulting in damage to the conductor in the jack; on the contrary, if the pin diameter is too small, when the pin and the jack fit, the gap between the pin and the wall of the jack is too large, and the two inside of the connector If the conductor cannot be contacted closely, the contact resistance will increase, and the electrical performance index of the connector will be very poor.

Improvement method: whether the fit of Jack and pin is reasonable or not can be measured by the insertion force and retention force when the standard gauge pin and the conductor in Jack fit. Therefore, we can take the insertion force and retention force as an inspection standard, and adjust the dimensions and tolerances of the jack and the pin, as well as the aging treatment process of the conductor in the jack, so that the insertion force and retention force between the pin and the jack are in a proper range.

USB, the abbreviation of universal serial bus in English, is an external bus standard, which is used to regulate the connection and communication between computers and external devices. It is an interface technology applied in the field of PC.

Universal serial bus (USB) is a new data communication mode which gradually replaces other interface standards. It was jointly developed by Intel, Compaq, digital, IBM, Microsoft, NEC, Northern Telecom and other computer companies and communication companies in 1995, and gradually formed industry standards. As a kind of high-speed serial bus, USB bus's extremely high transmission speed can meet the application environment requirements of high-speed data transmission, and the bus also has the advantages of simple power supply (bus power supply), convenient installation and configuration (plug and play and hot plug are supported), simple expansion port (127 peripherals can be expanded at most through the hub), diversified transmission modes (4 transmission modes ）, as well as the advantages of good compatibility (downward compatibility after product upgrade).

Since its introduction, the universal serial bus has successfully replaced serial port and parallel port and has become one of the standard expansion interfaces and necessary interfaces for a large number of computers and intelligent devices in the 21st century. Now it has developed to USB version 3.2. USB has the advantages of fast transmission speed, convenient use, hotplug support, flexible connection, independent power supply, etc. it can connect a variety of peripherals such as the keyboard, mouse, large-capacity storage device, etc. the interface is also widely used in smartphones. The interaction between intelligent devices such as computers and external data is mainly based on network and USB interface.

1. polarization

The USB connector can only be nominally inserted in one way. It is possible to force a wrong connector, but this can cause damage to the device.

2. At least four contacts

All USB connectors have at least four contacts (some USB models may have five, USB 3.0 connectors or more), which are used for power, ground and two data lines (D + and D -). The USB connector is designed to transmit 5V up to 500mA.

3. shielding

The USB connector is shielded, so it provides a metal shell that does not belong to the circuit, which is very important to keep the signal intact in the environment with a lot of electrical "noise".

4. Powerful power connection

It is very important for the power pin to establish a connection before the data line to avoid trying to power the device through the data line, which is taken into account in the design of all USB connectors.

5. Mould strain relief

All USB cables are plastic-wrapped at the connector to prevent pressure on the cable and damage to the electrical connection.

Degreasing treatment is performed with aid of an aqueous solution containing detergents.

The detergents emulsify oil present on the material to be treated; for this reason, oil concentration tends to increase in degreasing baths until the need for renewal and/or replacement, to avoid loss of efficacy.

Using ceramic membrane technology, there has two fluids, one is permeated which is constituted by water and detergents present in the original bath, the other is concentrate which contains oils and suspended solids and that is back to oil removal tank. After ceramic membrane treatment, the concentration of oil in the degreasing tank can be maintained at a low and very stable concentration range, the quality of the cleaned steel plate is uniform. The emulsion oil in the waste liquid is subjected to demulsification to reduce the amount of surfactant used in the cleaning solution.

Separation principle

Selecting the appropriate ceramic membrane filtration precision, by utilizing the characteristics that oil molecules and water molecules differ by tens of times in size and hydrophilic membrane surface properties of ceramic membrane, oil molecules can be effectively rejected, and water, degreasing bath, and surfactant small molecules can be recycled through the membrane surface. The degreasing bath is concentrated by the ceramic membrane system, and the volume of the discharged waste liquid is greatly reduced.

Technical benefits

1. Oil is removed and decreasing baths can be recycled ;
2. Costs of adding chemicals are significantly reduced;
3. The usage of surfactant is greatly reduced because of SS removal ;
4. Regeneration period is prolonged to 6 months or more ;
5. Subsequent wastewater treatment cost is decreased ;
6. Longer service life, lower operating pressure and lower energy consumption;
7. Simple, compact, fully PLC control
8. Ceramic membrane has excellent chemical resistance, high-temperature resistance and high separation precision
