1. Plate frame filter press filter plate loosens or even leaks oil
Common filter press hydraulic failures and pressures remain unsuitable and hydraulic cylinders are not propelled. The main reasons for the inability to maintain pressure are oil leakage, O-ring wear and improper operation of the solenoid valve. The usual treatment methods are to remove and inspect the valve, replace the O-ring, clean the check solenoid valve or replace the solenoid valve. If the hydraulic cylinder of the filter press is not suitable for propulsion, it is obvious that the air is sealed inside. At this time, as long as the system is pumping air, it can be quickly solved.
2. Plate frame filter press filter plate walks slowly or even falls off
At this time, it is necessary to clean the guide bar in time and apply butter to ensure its lubricity. It should be noted that it is strictly forbidden to apply thin oil on the guide rod of the filter press, because the thin oil is easy to fall and the bottom is very slippery. It is easy for the personnel to fall and fall under the operation and maintenance, resulting in personal injury.
3. The frame filter press filter plate has groove marks
1. Clean the groove, leak out the fresh surface, and clean it with a small saw blade.
2, black and white two repair agents in a ratio of 1:1
3. Apply the prepared repairing agent to the groove and apply it slightly higher.
4. Quickly set the filter cloth of the filter press, squeeze the filter plate of the filter press together, make the repair agent and the filter cloth of the filter press stick together, and squeeze the groove at the same time.
5. After squeezing for a period of time, the viscose is naturally formed and no longer changes. At this time, it can be used normally.
4. The filter cake of the plate and frame filter press is uneven or not formed.
The main solutions are: increase feeding, adjust the process, improve the feeding, clean the filter cloth filter cloth or replace the filter cloth filter cloth, clean the blockage, clean the supply hole, clean the drain hole, clean or replace the filter press Filter cloth, increase pressure or pump power, low pressure start, continuous pressurization and other methods.
5. Plate frame filter press frame damage
The corresponding solution has a note of 4 points:
1. Use a nylon cleaning blade to remove the mud from the feed port.
2, complete this cycle, reduce the filter plate filter volume
3. Check the filter cloth of the filter press, clean the drain, check the outlet, open the corresponding valve, release the pressure
4. Carefully clean the filter plate and repair the filter plate of the filter press.
6. Water seepage between the plate and frame filter press
Solution:
The treatment method of water seepage between the frame of the frame filter press is relatively simple, as long as the hydraulic pressure is increased, the filter cloth is replaced, or the block of the sealing surface is removed by using a nylon scraper.
A urinary tract infection (UTI) is an infection in any part of your urinary system - your kidneys, ureters, bladder and urethra. Most infections involve the lower urinary tract - the bladder and the urethra.
Women are at greater risk of developing a UTI than are men. Infection limited to your bladder can be painful and annoying. However, serious consequences can occur if a UTI spreads to your kidneys.
Doctors typically treat urinary tract infections with antibiotics. But you can take steps to reduce your chances of getting a UTI in the first place.
