The precautions for using stainless steel acid and alkali resistant, corrosion resistant industrial oil mist filters mainly include the following aspects:
I. Installation Precautions
Space Requirements:
Choose an installation location with sufficient space to facilitate operation and maintenance. For small filters, at least 0.5 to 1 meter of space should be reserved around them; for large filters, the reserved space may need to be larger.
Piping should provide appropriate support to avoid additional tension or pressure on the filter due to the weight of the piping itself or water (air) flow impact.
Environmental Conditions:
The installation environment should avoid adverse factors such as humidity, high temperature, and corrosive gases. Excessive humidity may cause electrical components to become damp and damaged; high temperature environments may affect the performance and service life of the filter; and corrosive gases may corrode the filter's housing and internal components.
Install the filter on a stable ground or platform to prevent it from tilting or shaking, which may affect its normal operation.
Connection Methods:
When connecting inlet and outlet water (or air) piping, ensure that the connection method is correct, such as using welding, flange connections, or threaded connections.
Welding connections should ensure welding quality to avoid weld seam leakage; flange connections should pay attention to the sealing of the flange, use appropriate sealing gaskets, and tighten the bolts to the specified torque; threaded connections should ensure that the threads match and wrap with sealing tape to prevent leakage at the connection.
Grounding Protection:
If the filter has electrical control components, such as differential pressure controllers, electric valves, etc., good grounding protection must be provided. The grounding resistance should meet relevant standards, generally requiring no more than 10 ohms, to prevent electrical leakage accidents and ensure the safety of operators.
Voltage and Frequency Matching:
Ensure that the power supply voltage and frequency match the rated values of the filter's electrical equipment. If the voltage is too high or the frequency does not match, it may damage the electrical components and affect the normal operation of the filter.
II. Operation and Maintenance Precautions
Startup and Operation:
The equipment should be used for as long as possible after startup, as frequent startups and shutdowns can shorten the equipment's lifespan.
It is absolutely prohibited to open the inspection door during operation. If inspection is needed, the power must be turned off first.
Professional Operation:
Only professionals can open and dismantle the equipment.
Installation, disassembly, or maintenance of the filter must be performed by professionals and is strictly prohibited from being operated by individuals without authorization.
Regular Inspection and Maintenance:
Regularly inspect the appearance of the filter to check for leaks, corrosion, deformation, etc. For minor corrosion spots on the housing, promptly address them, such as using anticorrosive paint for repair.
Regularly check the pressure and flow at the inlet and outlet of the filter and record relevant data. If the pressure difference increases beyond the normal range (usually specified by the equipment manufacturer, generally around 0.05~0.1 MPa), it may indicate a clogged filter element that needs to be cleaned or replaced in a timely manner.
The replacement cycle of the filter element depends on factors such as the nature of the filtered medium, filtration accuracy requirements, and usage frequency. When the filtration accuracy of the filter element decreases significantly, cannot be restored to normal levels after multiple cleanings, or the filter element is damaged or deformed, it needs to be replaced.
Regularly check the operation of the backwash mechanism, including whether the suction cup works properly and whether the drain valve can be fully opened and closed.
Regularly check the accuracy of the differential pressure controller, which can be calibrated by comparing it with a standard pressure gauge.
Inspect the sealing parts inside the filter, such as O-rings and sealing gaskets. If the sealing parts are found to be hardened, deformed, cracked, etc., they should be replaced in a timely manner to ensure the sealing performance of the filter.
Safety Precautions:
Do not store flammable or explosive materials around the filter, and strictly prohibit open flame operations below the filter.
Never inject substances that should not enter the filter into it to avoid damaging the filter.
During the operation, cleaning, and repair of the filter, wear labor protection equipment that complies with operating procedures.
Any maintenance operations should only be performed after confirming that safety conditions such as shutdown and liquid source interruption are appropriate.
Follow operating procedures and never operate blindly or change parameters arbitrarily.
Record the operating parameters and operating conditions of the filter on a regular basis, and conduct regular safety inspections and technical assessments.
In the case of abnormal conditions during use, notify relevant personnel for handling in a timely manner.
When replacing parts, please use components that meet the requirements and use consumable parts specified by the manufacturer.
