How to replace the filter element of HC8300FKS30H-YC11 wind turbine gearbox

How to replace the filter element of HC8300FKS30H-YC11 wind turbine gearboxBy using fiber filtration method, dust can easily fall into the dust storage container, and back blowing can peel off viscous impurities stuck to the filter cartridge, which will not affect the dust removal efficiency of the filter cartridge or pollute the environment. And it greatly increases the service life of the filter cartridge. This indirectly saves expenses and energy. Under the influence of advanced technology and sophisticated manufacturing processes, dust removal filter cartridges have the characteristics of corrosion resistance, pressure resistance, strong dirt absorption capacity, high filtration accuracy, poor adsorption, low probability of blockage, and strong moisture resistance

How to replace the filter element of HC8300FKS30H-YC11 wind turbine gearbox

Before entering the interior of the filter element, the ash stored in the ash hopper must be completely emptied and thoroughly ventilated to check for any harmful gases before starting work. When working inside the electrostatic precipitator, it is necessary to strictly follow the work permit system, stop using the electric field and its equipment, isolate the power supply, block the passage of flue gas, and ensure that the temperature of the dust collector drops below 40 ℃. The working area must be reliably grounded and reliable safety measures must be formulated. What are the characteristics of its application? The filter element of wind turbine gearbox has a large filtering area, high temperature resistance, and corrosion resistance. Features applicable to liquids with high viscosity.

Its products are used in various locomotives, industrial equipment, large hydraulic stations, hydraulic pumps and other hydraulic systems. The hydraulic filter element is directly installed inside the oil tank, simplifying the system's piping, saving space, and making the system more compact. When repairing the system, the oil in the tank will not flow back. When replacing the hydraulic filter element, it can carry the pollutants inside the hydraulic filter element out of the oil tank together, so that the oil will not flow out. The return oil filter element is equipped with a bypass valve: when the hydraulic filter element is blocked by pollutants and the pressure difference reaches 0.35MPa, if the filter element cannot be replaced immediately, the bypass valve located at the top of the filter element will actively open (with a pressure difference of 0.4MPa) to protect the normal operation of the system. Equipped with magnetic devices: capable of filtering out ferromagnetic particles of more than 1LJm in the return oil.

Wind power gear filter replacement operating procedures: 1. Turn off the gearbox oil pump to prevent automatic pressure during filter replacement from causing injury. 2. Replace the fan after half an hour of shutdown to prevent excessive oil temperature.

3. First, drain the oil from the filter before replacing it. Before starting the operation, it is necessary to confirm that the motor is in a stopped state. And cut off the power supply of the gearbox oil pump, remove the oil drain plug, open the oil drain valve to drain the lubricating oil from the filter cartridge, to prevent oil overflow when replacing the filter element.

4. Remove the exhaust hose from the filter cover and then rotate it counterclockwise to remove the filter cover. Before disassembly, make sure that the fastening ring between the upper cylinder and the cylinder is locked to prevent the upper cylinder from rotating during the disassembly process.

5. Remove the filter element. If it is difficult to remove the filter element, shake it to help remove it and place it in the waste oil bin.

6. Check for debris and similar objects in the filter and oil tank. If there are large particles, it indicates that there may be problems with the gearbox parts. As needed, clean the filter, oil tank, filter holder, top cover, check the sealing ring, and replace it if necessary. If only the filter element needs to be replaced, clean the collection plate and rotate it counterclockwise to remove it. After cleaning, reinstall it into the slot of the new filter element.

7. Carefully install the new filter element onto the bracket and ensure that it is properly installed. Before installing the new filter element into the filter, confirm that the sealing ring at the bottom of the filter element is intact and undamaged, and then align the filter element vertically to ensure that it is accurately installed into the filter seat and in place. 8. Insert the new filter element, tighten the oil drain valve, install the sealing ring of the filter cover to prevent oil leakage, tighten the fixing screws, and tighten the exhaust screws of the filter cover.

9. Before turning on the oil pump, unscrew the ventilation pipe on the side of the gearbox, turn on the pump, and wait for the air inside the filter to be exhausted. If there is oil flowing out, tighten the exhaust pipe and retract it twice to prevent unfiltered oil from directly entering the gearbox during normal operation and causing pollution.

10. Turn on the lubrication system and check if the filter is leaking oil.

11. Conduct pressure testing, check if the gearbox oil pressure and inlet oil pressure are within the normal range, if the filter transmitter is functioning properly, if so, it can operate normally, and if the gearbox filter element has been replaced
