How to solve common problems with rolling diaphragm products? The rubber diaphragm industry absorbs the oil stains inside and outside the printing and dyeing process at a voltage of approximately one torch before principle design, making it very suitable for non corrosive fluids with a temperature of -40 ° C.
In addition to considering the leakage of oil in the filter press, and considering various factors such as the nylon series of the filter press, air distribution temperature resistance, and temperature, it is determined; Materials include: rubber, cast iron, stainless steel, carbon steel, stainless steel, alloy, steel, etc. There are also various material choices, including metal, cast steel, stainless steel, alloy steel, engineering plastics, lining (rubber lining, fluorine lining).
Diaphragm filter press is an intermittently operated pressurized filtration equipment suitable for solid-liquid separation of various suspensions and for various corrosive media at high temperatures or 80 ° C.
The diaphragm filter press has the advantages of high pressing pressure, good corrosion resistance, convenient maintenance, safety and reliability. It is the first choice for customers in industries such as metallurgy, gas, papermaking, coking, pharmaceuticals, food, brewing, and fine chemicals.
Diaphragm filter presses have been widely used in various fields that require solid-liquid separation. Diaphragm filter press is considered as an alternative upgrade equipment for ordinary box filter press.
The diaphragm filter press has shown good results in terms of processing capacity per unit area, reducing filter cake moisture, and adaptability to the properties of the processed materials.
The diaphragm filter press is applied to sludge and sewage treatment, and the minimum moisture content of the filter cake has reached below 60%. Compared to traditional box type filter presses, the solid content of the filter cake can be increased by more than 2 times, and the transportation cost of the filter cake is greatly reduced. The filter cake can enter the power plant for direct combustion, truly turning sludge into a resource and sewage into a clear spring, completely replacing the box type filter press.
Firstly, the foundation of the diaphragm filter press should be leveled before installation, and the levelness error of each installation reference plane should not exceed 2mm.
Install the oil cylinder support and level it with a pad. The upper planes of the two supports are on the same horizontal plane, and the bolts between the oil cylinder and the support are not tightened. Then, install the oil cylinder on the oil cylinder support and tighten the foundation bolts.
After installation, the tail plate should be leveled, and another main beam should be installed and fixed with a clamp. The positioning clamps between the two main beams and the tail plate should be installed in place without leaving any gaps.
Align the diaphragm. Adjust the main beam with a Dumpy level, insert the round mouth on the two main beams, and fix it with a splint. The positioning bayonet between the two main beams and the tailboard should be installed in place without leaving a gap.
Due to the expansion of the bolt holes on the diaphragm of the pulse valve, the tetrafluoroethylene changes quickly and still operates normally at temperatures below 0-3 ° C;
Technical requirements for pulse valve diaphragm: Due to the fact that the pulse valve diaphragm is a flexible mechanism that requires frequent opening and closing actions to control air flow, and requires good flexibility, as well as the highest possible sealing, the material of the pulse valve diaphragm is directly related to the service life and effectiveness of the pulse valve diaphragm.
