Screw fan for waste gas purification of metallurgical plant
1. The rotor uses a large shaft diameter design, which provides increased shaft rigidity and load-bearing capacity.
2. The support end is equipped with a combination of four-point radial thrust bearings and cylindrical roller bearings, which provides the bearings with sufficient load-bearing capacity and stability under extreme conditions, prolonging the service life of the bearings.
3. The housing is constructed with a center joint, which ensures uniform stress distribution and increases the overall load-bearing capacity of the housing; the design with large reinforced ribs increases the housing rigidity, ensuring reliable operation at high pressures.
4. A splash lubrication system is used, which results in low power consumption for oil mixing, ensuring a stable supply of lubricating oil to gears and bearings.
1. Screw air compressor: Mainly used in the field of air energy to drive various pneumatic tools. With the advancement of oil-gas separation and gas purification technology, it is also increasingly used in areas that require very high air quality, such as the food, pharmaceutical, and textile industries, taking over many markets previously occupied by oil-free air compressors.
2. Screw-type process compressor: Used for compressing gases in various process streams, such as carbon dioxide, ethylene, methane, hydrogen, natural gas, and flame gas.
3. Air compressor repurposed for technological use: This type mainly involves the conversion of rotary screw air compressors for the purpose of compressing technological gases. These models often have a low cost, but very limited applicability, being suitable only for a specific type of gas.
The HL618 series of screw air blowers is a new product developed by Shandong Zhanggu based on many years of experience in design and manufacturing to meet the market's needs for energy conservation and environmental protection. This series of screw air blowers features a compact design, stylish appearance, high efficiency, low noise, reliable operation, and long service life. They are particularly suitable for medium and low flow, high pressure applications and are an ideal air source widely used in industries such as metallurgy, machinery, chemical industry, geology, and energy.
Daily maintenance points
1. Check the air filter element and the coolant level;
2. Check the hoses and all pipe connections for leaks;
3. Check the records, and if the consumables have reached the replacement deadline, the machine must be stopped for replacement;
4. Check the records, and when the exhaust temperature of the main engine reaches or approaches 98 ° C, it is necessary to clean the oil cooler;
5. Check the records, and if the pressure difference in the separator reaches 0.6 BAR or higher (the limit is 1 BAR), or if the pressure difference starts to show a trend of decrease, the machine should be stopped for replacing the separator element;
6. Check the condensate drain, and if the drainage is too slow or there is no condensate drain, the machine must be stopped for cleaning of the water separator.
Monthly Maintenance Elements
1. Check the surface of the oil cooler and clean it if necessary;
2. Clean the cooler after the maintenance is completed;
3. Clean the water separator;
4. Check all electrical connections and secure them;
5. Check the contacts of the air conditioner contactor;
6. Clean the dust from the engine air intake and the surface of the engine housing;
7. Clean the return oil filter.
Quarterly Maintenance Elements
1. Add lubricant to the main engine;
2. Clean the main motor and fan motor;
3. Replace the coolant;
4. Replace the oil filter element;
5. Clean the oil cooler.
