The rolling diaphragm product has ushered in a huge transformation, with effective, safe, and persistent quality, perfect after-sales service, ensuring thoughtful service, and achieving good economic benefits.
The diaphragm filter press is composed of a diaphragm plate and a box type filter plate. Diaphragm filter presses have the advantages of high pressure, good corrosion resistance, easy maintenance, safety and reliability, and are widely used in industries such as metallurgy, gas, papermaking, coking, pharmaceuticals, food, brewing, and fine chemicals.
The difference between diaphragm filter press and other filter press equipment lies in the structure of the filter chamber. The solid blocking medium of the diaphragm filter press is a polypropylene integral diaphragm and a rubber diaphragm, while the medium of the ordinary filter press is a fiber woven filter cloth, with significant differences in medium materials. The diaphragm filter press can also perform secondary expansion pressure to further dry the filter cake.
The important function of the bearings of the diaphragm filter press is to guide the rotation of the shaft and also to support the idle parts on the shaft, mainly to reduce friction. If there were no bearings, the noise would definitely be high, and the noise would be small and the damage to the equipment would be incalculable.
The working process of a diaphragm filter press cannot be separated from wastewater and sludge, which cause great damage to the bearings. The selected bearings need to be wear-resistant, so the requirements for sealing and lubrication are very high.
When using the diaphragm filter press equipment for a long time, it is necessary to use hydraulic oil at a frequency of 07 Hz and SN at a frequency of wire
When using diaphragm filter press equipment for a long time, hydraulic oil seems to have an indispensable role in purifying air. Therefore, the washing method of diaphragm filter press refers to most industry filter presses on the market today.
The accessories of the shield tunneling frame filter press box type filter press diaphragm filter press equipment are close to vacuum equipment for sludge. The filter plate of the shield tunneling frame filter press is sandwiched on both sides of the filter plate to accelerate the washing of the filter cloth through the filtrate, thus achieving the goal of solid-liquid separation.
Filter plate of filter press: The common filter press cannot maintain hydraulic faults and pressure, so it is not suitable to use hydraulic cylinders for propulsion. Oil leakage, O-ring wear, and abnormal operation of solenoid valves caused by inability to maintain pressure. The common handling method is to disassemble and inspect the valve, and replace the O-ring.
The box type filter press is an ideal equipment for separating the solid and liquid phases of suspension. To obtain a slightly dry filter cake and further reduce the moisture content of the filter cake, the machine is equipped with rubber diaphragm (integrated, embedded, and split) filter plates or PP polypropylene integrated diaphragm filter plates to press the filter cake< eod>。
