classification of industrial dust vacuum to open the inspection door every week, check whether the dust bag is normal, surface area powder is too much phenomenon, and find the cause, troubleshoot. If the fault is found, it should be stopped in time, find the cause, and then use it after repair. The equipment should keep the pulse controller surface clean. classification of industrial dust vacuum Every 1000 hours need to add a LC-250 high drop point synthetic grease to the air pump bearing, replace the grease once a year. During the use of the equipment, the air pump filter is cleaned once every half month to ensure that the gas path is smooth. classification of industrial dust vacuum Often check the grease of the fuel tank of the fan reducer motor and make it up in time. classification of industrial dust vacuum Check the large film in the pulse valve 1 to 2 times a year, and replace the damaged and aging ones in time.
classification of industrial dust vacuum What should be paid attention to during the test?
First, tour inspection: tour inspection of the dust removal system (especially the dust collector), mainly to observe the dynamic operation of the no-load test, find problems, timely deal with the potential uncertainty of the dust removal equipment installation process, correct errors, and improve the integrity of the dust removal equipment.
Second, the treatment of major hidden dangers should focus on the spirit, take technology on the basis of viewing and discussing, buy even remove defects, and improve the quality of equipment installation.
Third, test verification: for the defects and hidden dangers found in the no-load test, after repair and treatment, it should be verified by one or more test runs; To be confirmed by test run verification. Reach the design target.
4, dealing with defects: equipment defects and hidden dangers found in the process of no-load test should be recorded, carefully discussed, and repaired measures should be taken to prevent future problems.
5. No-load operation: in the no-load (no dust) state, organize and observe the operating conditions of dust removal equipment, especially the voltage, current, speed and vibration of the main fan, as well as the air volume, resistance, electric field characteristics and other indicators of the dust collector; Macro qualitative evaluation of the integrity, continuity and applicability of the dust collector operation, the overall function of the equipment matching, continuous operation, suitable function.
classification of industrial dust vacuum The motor and fan are arranged in the upper shell, the dust filter bag, the drop hopper and the dust hopper are arranged in the lower shell, the dust filter is arranged between the upper shell and the lower shell, the dust filter bag is connected with the dust filter frame, and the elastic sealing pad is arranged between the frame and the dust filter frame. The vibration motor is connected with the dust filter frame through the vibration mechanism, the air intake is arranged on one side of the lower shell, and the air outlet is arranged above the upper shell. The motor and the vibration motor are respectively connected with the electric control box. The dust collector has the characteristics of compact structure, easy operation, low noise, good dust removal effect, and can be directly applied to small places and laboratories.
The working principle of classification of industrial dust vacuum is to use the induced draft fan for air volume transport so that the dust-containing gas enters the box through the dust collector inlet, and the dust-containing gas is filtered through the filter bag through the gas distribution, and the dust is left on the inner surface of the filter bag. The purified gas enters the induced draft fan through the filter bag and is discharged by the exhaust pipe. After the dust collector works for a period of time, the dust on the filter bag gradually increases, resulting in an increase in the resistance of the dust filter bag, and the dust collector needs to be cleaned. After the dust removal is completed, the dust collector works normally. classification of industrial dust vacuum With the increase of filtration time, the filter bag residual adsorbed dust more and more and affect the normal dust removal work, using the shutdown shaking vibration for tens of seconds, so that the residual dust attached to the internal surface of the filter bag shake off. Dust falls into the ash bucket, drawer or directly onto the conveyor belt.
