Membrane Filter Press Hydraulic Oil Precautions

According to our long-term understanding of diaphragm filter press hydraulic oil, we have conducted some relevant tests. The emulsification deterioration of the diaphragm filter press hydraulic oil refers to the fact that the hydraulic oil initially contains a large number of water molecules, resulting in the emulsification of the hydraulic oil.

In the daily work of the diaphragm filter press, there are often several situations in which the hydraulic oil can make the hydraulic oil into the water. One is that the filter press is used in the open air for a long time, alternating hot and cold, or often wet by rain. The sealing performance of the pipeline with hydraulic oil flow path, hydraulic chamber, oil pump station and other important parts slowly deteriorates over time, which may lead to a small amount of water molecules into the oil pump station. When water molecules enter the oil pump station and come into contact with the hydraulic fluid, the water remains as a large amount of water suspended in the hydraulic fluid over time. At this time, as long as the motor passing through the oil pumping station is pumped and squeezed by the greater pressure in the hydraulic chamber, the water mass is rapidly decomposed into water molecules, uniformly dispersed around the molecular mass of hydraulic oil. Hydraulic oil after a certain period of oxidative deterioration, will slowly become white, and at this time the mixture in a large pressure environment can not maintain the original volume, the intermolecular gap is also larger.

Membrane Filter Press Hydraulic Oil Precautions

When the membrane filter press oil pump pumps such a hydraulic oil chamber and exerts pressure on the piston, the force between the objects is mutual, so the piston will exert the same force as the hydraulic oil, and then the hydraulic oil of the filter press will slowly change and reduce the pressure of the filter press. This is the reason why there can only be a very small filter press pressure when the hydraulic fluid enters the water. People who use filter press equipment for a long time will encounter a series of phenomena, such as the increase of impurities in the hydraulic oil after a period of time, or the hydraulic oil becomes white and does not adhere, which is the result of the deterioration of the hydraulic oil emulsification.
