Attention to Summer Palace and maintenance of vertical filter Press

Vertical filter Press Summer Palace and maintenance of attention matters:

OneVertical Filter PressDebugging normal can feed work, each shift before the work of the whole machine to make a comprehensive inspection. Mechanical compaction transmission parts and gearbox must be full of smooth oil; hydraulic compaction review tank oil storage and hydraulic station working pressure, hydraulic oil ordinary change once a year, change when the hydraulic system to do-a comprehensive cleaning, hydraulic station working pressure is less than the cylinder maximum operating pressure, but the minimum can not be less than the filter pressure allowable value, Too small will provoke a large leakage, through the General Assembly damage to the machine parts.

2,Vertical Filter PressStop the condition that the filter plate is less than the regular number of the factory boot work, so as not to damage the parts. Check the arrangement of filter plate before feeding, filter cloth can not have folding phenomenon, to avoid seizures of large leakage; After unloading the filter plate must be close to the compression arrangement uniform.

3, to all normal front can press the filter plate pressurized filtration, filtration pressure and filtration temperature must be within the rules range, filtration pressure too high will cause leakage, filter temperature through the high plastic filter plate easy to deform, feeding when the suspension should be average concentration. No confounding material; filter cloth and filter plate after unloading cake must be rinsed clean, do not allow residue paste in the sealing surface or feed channel, otherwise it will affect the smooth feed and sealing of the filter plate, so that the pressure on both sides of the filter plate is not balanced, resulting in deformation damage of the filter plate.

4, filter Cloth selection must be in line with the filter paddle filtration technology request, the new filter cloth should be shrunk before manufacture, the opening diameter should be less than the filter plate aperture, supporting the filter plate when the Buchon and plate holes should be relatively concentric, feed hole cloth should be fastened to the cylinder wall, otherwise it will form, filter is not clear, the filtration rate is low, the cloth cylinder break, can not reach the expected filtration purpose results.

5,Vertical Filter PressIn the early stage of pressure filtration, the filter is cloudy, and when the filter cloth constitutes a layer of filter cake, the filter will become clear. If the filter is constantly cloudy or mixed, it may be damaged filter cloth or buchon and plate hole bias, at this time to close the valve or stop the feed change filter cloth. A small amount of leakage is allowed between the filter plates capillary phenomenon the filter cloth.

6, move the filter plate, force should be average appropriate, not collision, wrestling, so as not to damage the sealing surface and filter wrench. Filter cloth After a period of time will harden, performance landing, for this need to be regularly checked, if found to change the impact of the filter rate phenomenon, you can use the corresponding low concentration of weak acid weak alkali to stop and clean, so that the filter cloth recovery function, can not recover in time to change.

7, slurry, lotion or tightening air valve, must be activated according to the operating procedures, can not be enabled at the same time, estrangement squeezing when tightening air pressure can not exceed the filtration pressure.
