oil leakage in the oil pipe of plate and frame filter press reasons
The manufacturer explains the reasons for the oil leakage of the oil pipe of the plate and frame filter press. The oil leakage of the oil pipe of the plate and frame filter press is generally caused by the frequent use of the filter press and the vibration of the machine, but it is also caused by other circumstances. What is the specific reason? Like other equipment, the motor of the filter press will make a sound when it is running, but it is found that the motor sometimes makes an abnormal sound when it is often used, What's the reason? The motor is aging and the load can't bear; the high-pressure oil pump is damaged. Generally, the high-pressure oil pump is a plunger pump. If the hydraulic oil is abnormal or the service life is long, the plunger will be damaged; when the hydraulic station is installed, the coupling is not concentric, and if the coupling is not placed correctly, the motor will swing too much and the load will increase. Now, many plate and frame filter presses are installed with flap devices, The main function of the flap is to collect the liquid, especially the filtered material. With this collection, it will be better. After filtration, when the filter plate is loosened, the feed pipe will collect the liquid more or less. If the filter cake is first concentrated in the mud bucket, with the flap, the liquid in the pipe will not enter the mud bucket, and the filter cake in the mud bucket will be kept dry
Filter cloth of filter press is placed wrongly. There are many reasons why the filter chamber cannot be sealed. We need to start from a simple point of view, around the filter chamber, to see if the filter cloth is wrinkled, or the edge of the filter cloth is incomplete. Because the structure of the filter chamber is formed by cutting between the filter plate and the filter cloth, which is supported by strong pressure, generally the filter plate is not easy to have problems, and the rest is the filter cloth. In order to form a seal between the rigid filter plates and the filter cloth that plays a key role, the wrinkle or incomplete of the natural filter cloth will easily cause a gap between the filter plates, and the natural filter chamber will not form a seal. Insufficient pressure. The filter plate and the filter cloth must be under strong pressure to realize the closed filter chamber structure. When the pressure is insufficient, the pressure applied to the filter plate is less than the pressure of the filter liquid, and the natural filter liquid will naturally permeate out of the gap.
