Installation Position for ZNGL0201180 Filter Element in Pulverizer Hydraulic Oil Station
In industrial production, the stable operation of equipment like pulverizers (coal mills) and primary air fans is directly related to production efficiency and cost control. Issues such as equipment failure, frequent maintenance, and oil contamination often pose significant challenges for businesses. However, selecting the right filter element can easily resolve these problems. Focusing on the filtration of pulverizer hydraulic oil stations, this guide details how various filter elements safeguard equipment and provides a clear view of the practical benefits they deliver.
I. Pulverizer Hydraulic Oil Station Filter Element ZNGL0201180: Eliminating Hydraulic System Failures
The hydraulic system is the "power heart" of the pulverizer. If the oil is contaminated with impurities, it can lead to minor issues like hydraulic valve sticking or severe problems like equipment shutdown, causing enormous losses. The ZNGL0201180 filter element is designed to address this pain point, protecting the stability of the hydraulic system from the source.
1. Key Performance Parameters of ZNGL0201180 Filter Element
| Performance Metric | Specific Parameter | Value to the Customer |
| Filtration Accuracy | 5 um | Precisely filters microscopic impurities in hydraulic oil, preventing wear of hydraulic valves and cylinders. |
| Material | Glass Fiber + Metal Skeleton | High-pressure resistant, anti-corrosion, 30\% longer service life than ordinary elements, reducing replacement frequency. |
| Operating Pressure | 31.MPa} | Adapted to the high-pressure conditions of the pulverizer hydraulic system, preventing damage from excessive pressure. |
| Contaminant Holding Capacity | 80 | Accommodates more impurities, extends the filter replacement cycle, and lowers maintenance costs. |
2. Actual Application Scenario
In the hydraulic oil stations of pulverizers at thermal power plants and metallurgical plants, the ZNGL0201180 filter element continuously filters metal debris, dust, and other impurities from the hydraulic oil, ensuring stable hydraulic system pressure and preventing pulverizer shutdown due to hydraulic failure. After installing this filter element, a power plant saw its pulverizer hydraulic system failures drop from 2-3 times per month to less than once per quarter, saving over $¥100,000$ in annual maintenance costs.
II. Pulverizer Lubrication Oil Station Filter Element ZNGL02010201: The "Lubrication Butler" for Reduced Equipment Wear
The rotating components of the pulverizer, such as gears and bearings, rely on lubricating oil to minimize friction. If the lubricating oil is contaminated, it leads to accelerated component wear and shortens equipment life. The ZNGL02010201 filter element works collaboratively with ZNGL0201180 to safeguard the pulverizer's stability. A comparison between the two is provided below:
| Comparison Dimension | Pulverizer Hydraulic Oil Station Filter Element ZNGL0201180 | Pulverizer Lubrication Oil Station Filter Element ZNGL02010201 |
| Core Function | Protects the hydraulic system (power transmission) | Protects the lubrication system (reduces friction) |
| Filtration Accuracy | 5 - 10 um | 10 - 20um |
| Applicable Oil | Hydraulic Oil | Gear Oil, Lubricating Oil |
| Customer Value | Prevents shutdown due to hydraulic failure | Extends the life of gears and bearings, reducing major overhaul costs |
III. Duplex Filter Elements in Oil Stations: Enabling "Non-Stop Maintenance" and Boosting Production Efficiency
1. Filter Element ZNGL01010301
As a large piece of equipment, the HP1303 pulverizer's scheduled shutdown for maintenance can severely impact production schedules. The ZNGL01010301 duplex filter element adopts a "One-Duty/One-Standby" design, eliminating the need for shutdown when the filter element requires replacement. Operators simply switch the valve, perfectly resolving the conflict between maintenance and production.
| Advantage | Practical Benefit to the Customer |
| Duplex Structure (One-Duty/One-Standby) | Filter replacement requires no shutdown, ensuring continuous operation of the pulverizer and avoiding production losses. |
| Filtration Accuracy 20 um | Matches the requirements of the HP1303 pulverizer oil station, filtering oil impurities and protecting the equipment. |
| Temperature Resistance | Adapted to the high-temperature operating environment of the pulverizer, preventing failure due to overheating. |
2. Filter Element ZNGL01010201 (Adapted for Primary Air Fan GU24032-121
The primary air fan GU24032-121is a critical component of the ventilation system. If the oil station filter element fails, it can lead to fan bearing wear, resulting in abnormal noise, vibration, and even shutdown. The ZNGL01010201 duplex filter element is specifically designed for this fan, offering both high-efficiency oil filtration and non-stop maintenance capability.
IV. Common Filter Elements: Covering Multiple Scenarios and Solving Various Contamination Issues
In addition to the specialized filter elements mentioned above, the following filter elements for general-purpose filters can meet the filtration needs of different equipment, providing comprehensive contamination solutions for enterprises:
| Filter Element Model | Adaptation Scenario | Core Advantage | Customer Value |
| ZNGL02011001 | Hydraulic and Lubrication Stations (General Use) | 10um filtration accuracy | Adapts to multiple devices, reducing procurement costs. |
| ZNGL02010901 | High-Pressure Hydraulic Systems | 31.5MPa high-pressure resistance, anti-shock, 99% filtration efficiency. | Protects high-pressure equipment, preventing damage from pressure surges. |
| ZNGL02012001 | Low-Temperature Environment Equipment | low-temperature resistance, remains stable in cold regions. | Suitable for northern regions or low-temperature workshops, preventing filter element failure in cold weather. |
| ZNGL02010401 | Large Lubrication Oil Stations | Large filtration area, $100 \text{ g}$ contaminant holding capacity, long replacement cycle. | Reduces the frequency of filter element replacement in large equipment, lowering maintenance workload. |
