Troubleshooting of filter press

2016-02-20

Due to the plate and frame filter press is a set of automatic control system, its electric control system and hydraulic system is more complex, so the maintenance personnel must first be familiar with the working principle of the equipment, all kinds of valves and components working process, all the drawings. If you encounter more complex in the process of equipment operation fault, touch less than a clue, to be in line with to the once upon a time, from the principle of hard and soft. That is according to the fault phenomenon was level (PLC, frequency converter, the middle point) to the class (all kinds of valves), from hardware to software gradually eliminated, more flexible application according to the phenomenon and the circumstances. To be good at discovery in the production of small problems, often these small problems is the main root cause big fault

The Automatic Membrane /membrane filter press,chamber filter press,filter press machine .Filter press to solid-liquid separation through pressure, is a kind of intermittent solid-liquid separation equipment, is by the filter plate, filter box (plate and frame type) or by the filter plate (van) constitute a filter chamber, under the action of the pressure of transporting pump, sending material liquid into the filter chamber, through the filter medium, separate the solid and liquid.

Filter press is by far the most effective dewatering equipment, according to the type of the sludge, after it is dehydrated mud cake drying degree can reach 30% 80%. The basic construction of filter press is a welded frame, a series of filter plate and filter cloth. Filter cloth cover on the filter plate, in the process of pressure filtration, its intercept live solid particles and the fluid flow.

The space between the filter plate form the enclosure, trapped in the sludge has accumulated in them. At each end of each filter plate has a handle so they can be installed on the steel beam. Residue on the filter cloth, filtrate flow out. Filter plate have two pieces of filter cloth wrapped each page, the two pieces of filter cloth by wear plate central holes of a socket connection.
