What are the common faults of offline pulse dust collectors and their solutions?

The off-line ash cleaning pulse bag filter has a good dust collection effect under high dust concentration conditions, and the outlet dust concentration meets the environmental protection requirements. Some problems that are easy to occur in the process of use and solutions. 1. There are two main reasons for the poppet valve to jump and stop due to insufficient compressed air.

1. There are two main reasons for the poppet valve to jump and stop due to insufficient compressed air.

1.The oil-water separator between the air tank and the poppet valve is clogged due to dirty compressed air;

2.After the poppet valve runs for a long time, the seals wear out, causing compressed air to leak and resulting in insufficient air supply.

Workaround:1Add a set of oil-water separators, one open and one standby. When the filter element is found to be dirty, you can replace it with another set and clean the dirty one;

2.In addition to replacing the poppet valve seal in time, the following measures should also be taken: the air supply pressure of the poppet valve is adjusted between 0 25 0 5MPa to ensure that each poppet valve can act within the specified time, and the pressure should not be too high, otherwise it is easy to make the cylinder seal age, and when the air leakage point increases, the air supply pressure can be appropriately increased; Ensure the oil supply of the oil-water separator, and the oil supply speed should not be too small to avoid oil loss.

In addition, a certain amount of grease is added to the stem of the lifting cylinder. If you still don't understand anything, you can call the contact of Botou City Tongming Dust Removal**.

Let's talk about specific failures, and deal with specific failures.

I'm engaged in electrical appliances and the electrical problem is the pulse valve, the poppet valve controls the intermediate relay. Solenoid valve coil loves to burn. This is all controlled by a PLC module.

Judging the quality of the relay, the channel of the PLC module is generally shorted with the PLC power supply live wire. Check whether the relay operates and whether the auxiliary contact has voltage output. As for the quality of the solenoid valve coil, just measure it at the terminal.

The neutral line is a common line. When checking, measure the quality of the solenoid valve coil, if there is a short circuit, you can't short connect the PLC module, otherwise it will burn the channel. There is also the fact that the working air pressure of the pulse bag filter is not enough.

Pulse valves, poppet valves, damaged valve bodies or damaged diaphragms in the valves.

Summary. Hello, the reason why some pulses of DC24 pulse dust collector does not work is roughly as follows: pulse dust collector is a dust removal equipment with a small footprint and high dust removal efficiency.

Pulse dust collectors are very popular because they are flexible and easy to use, can effectively remove dust and maintain the cleanliness of the air. If the pulse valve of the pulse collector is not running and not working, the possible reasons are:

1) The power supply of the dust removal equipment is cut off, or the ash cleaning controller is out of order.

2) There are debris in the pulse valve of the dust removal equipment, which causes the pulse valve to leak all the time.

3) The pulse valve coil of the device is burned out.

4) The compressed air pressure of the equipment is too low.

Elimination method: 1) Restore the power supply, check whether the ash cleaning controller is out of order, if it fails, please repair it as soon as possible.

2) Check whether there is any debris in the pulse valve, and you can clean the pulse valve.

3) If the pulse valve coil of the device is burned out, please replace it in time.

4) Check whether there is any problem with the air system and the compressed air machine, and if there is a problem, please repair it as soon as possible.

DC24 Pulse Dust Collector Part of the pulse does not work for any reason.

Hello, the reason why some pulses of DC24 pulse dust collector does not work is roughly as follows: pulse dust collector is a dust removal equipment with a small footprint and high dust removal efficiency. Pulse dust collectors are flexible and easy to use, and can effectively remove dust and maintain the cleanliness of the air, so they are very popular with people.

If the pulse valve of the pulse dust collector does not run and does not work, the possible reasons are: (1) the power supply of the dust removal equipment is cut off, or the ash cleaning controller is out of order. (2) There are debris in the pulse valve of the dust removal device or the preparation, which causes the pulse orange flush valve to leak all the time.

3) The pulse valve coil of the device is burned out. 4) The compressed air pressure of the equipment is too low. Exclusion Method:

1) Restore the power supply, check whether the ash cleaning controller is out of order, if it fails, please repair it as soon as possible. 2) Check whether there is any debris in the pulse valve, and you can clean the pulse valve. 3) If the pulse valve coil of the device is burned out, please replace it in time.

4) Check whether there is any problem with the air system and compressed air machine, if there is a problem, please repair it as soon as possible, I hope mine can help you

I am a new equipment, I haven't used it yet, just installed the test machine, a total of 12 channels only 3 pulse valve action, the others are not responding, there are many possibilities. The pulse switch was not opened, the common end of the solenoid valve was short-circuited, and the fuse on the pulse meter was broken, and the differential pressure set value was not reached.

There are several reasons why some pulses of the DC24 pulse collector are not working:

Solenoid valve failure: DC24 pulse dust collector uses solenoid valve to control pulse jet cleaning, if the solenoid valve is faulty (such as coil breakage, magnetic core jamming, etc.), it will cause the corresponding pulse to not work.

Blocked or leaking gas paths: If the pulse line is clogged or leaking, the corresponding pulse will not work. For example, loose connections at the pulse line and material accumulation in the middle of the pulse line can cause gas path problems.

Controller failure: The controller of the DC24 pulse dust collector is the brain of the entire system, and if the controller fails, it will also cause some pulses to not work. For example, controller malfunctions can be caused by controller program errors, abnormal control signal transmission, etc.

Conveying fan grinding overload: If the conveying fan is overloaded, it will lead to a decrease in the conveying air volume, which will lead to insufficient pulses or some pulses do not work.

In view of the problem of dismantling by travel, the following measures can be taken to solve it:

Inspect and replace faulty solenoid valves.

Thoroughly inspect the gas path to remove blockages, repair leaks, and other issues.

Check whether the controller program and signal transmission file are normal, and replace the controller if necessary.

Carry out maintenance and maintenance of conveying fans to ensure their normal operation.

In short, when some pulses of the DC24 pulse dust collector do not work, it is necessary to find the fault and deal with it in time through detailed inspection and troubleshooting of the above problems.

The off-line ash cleaning pulse dust collector absorbs the advanced technology at home and abroad, adopts the advantages of the air box pulse bag filter and the long bag line occupied low-pressure pulse dust collector, solves the problem of "dust reattachment and loss of control" in the long bag pulse jet dust collector, and greatly improves the filter bag ash cleaning effect; The plugging device that can overcome the adhesion of dust to the ash hopper wall plate and the bridging of dust at the ash hopper ash discharge port is adopted, so that the dust collector can effectively control the dust of high concentration, strong viscosity and fine particle size dust points.

The dust collector is composed of the upper box, the middle box, the ash hopper, the air duct and the ash cleaning device of the chamber structure. During the work, the dusty gas enters the ash hopper from the inlet air duct, and after being separated by the diversion device, the fine dust particles enter the filter area of the middle box with the air flow, and the dust is isolated and attached to the outer surface of the filter bag, and the filtered gas enters the exhaust air duct from the upper box and is discharged to the atmosphere.

When the resistance of the dust collector reaches the limit value, the ash is cleaned according to the program: first close the exhaust duct of the ash cleaning room, so that the chamber is offline, and the filter bag is in a state of no air flow, and then, according to the program, the pulse valve is opened successively for row injection, and the compressed air is sprayed into the filter bag, under the action of vibration and reverse air flow generated by the expansion of the filter bag, the ash accumulated on the outer surface of the filter bag is separated from the filter bag and falls into the ash hopper, and is discharged by the ash discharge mechanism. Offline valves, solenoid pulse valves, ash discharge valves, and plugging devices are fully controlled by programmable control instruments.

The pulse bag filter controls each filter bag chamber to stop the filtration process and can use an off-line valve when cleaning. The commonly used is the DQT type starting push rod butterfly valve, which has a nominal pressure, a working temperature of 350 and a medium flow rate of 28ms.

The valve has novel design, flexible opening and closing, rapid switching, small flow resistance coefficient, easy to use and maintain, and is driven by a starting push rod, which opens and closes quickly and smoothly, and is a rapid cut-off equipment, as shown in the figure.

How to solve the problem after the failure of the pulse bag filter? The pulse bag filter is mainly used for dust removal work in the workshop, and the accumulated work will have a certain impact on the equipment, and it is inevitable that there will be some fault problems, so the following will introduce how to solve it.

1. The running resistance of the pulse bag filter is large.

The reasons could be:

1.filter bag compaction;

2.The pulse valve is not working or damaged;

3.The compressed air pressure is too low;

4.When the pulse valve is working, the poppet valve is not closed tightly;

5.One or more poppet valves are closed.

Exclusion method:1Cleaning the filter bags and strengthening ventilation;

2.maintenance or replacement of pulse valves;

3.Inspect the air circuit and air compressor;

4.Check the cleaning controller.

Second, the pulse bag filter has low running resistance.

The reasons could be:

1.Flue gas short circuit.

2.Broken filter bags;

Exclusion method:1Inspect the pipeline and repair the damaged area;

2.Inspect and replace the filter bags;

3. The pulse valve of the pulse bag filter does not work.

The reasons could be:

1.Power outage or ash cleaning controller failure;

2.There is debris in the pulse valve, and the air is leaking all the time;

3.The pulse valve coil burns out;

4.The compressed air pressure is too low;

Exclusion method:1restore power supply or repair cleaning controllers;

2.Carefully clean the pulse valve;

3.Replace the pulse valve coil;

4.Inspect the air system and compressor.

Fourth, the cleaning and replacement of filter bags.

In addition, there is a pulse bag filter bag filter bag in the use of the high viscosity of the filter cloth may cause the filter cloth to compaction, resulting in the increase of the resistance of the dust collector and affect the dust removal effect, after the above situation needs to be removed from the dust collector to rinse the surface of the filter cloth with clean water, and can continue to be used after the flushing is completed and dried.

After the pulse bag filter fails, the fan should be stopped, the compressed air should be stopped, and the power supply should be cut off. Find a professional dust removal engineer to repair and solve the problem.
