The pressure of the filter medium object of the diaphragm filter press

           The diaphragm filter press uses a special filter medium to exert a certain pressure on the object, so the rigid device for draining liquid is a commonly used solid-liquid evacuation device. The manual compression of the diaphragm filter press uses a screw-type rigid jack to push the compression plate to compress the filter plate. The rigid compression and compression mechanism of the diaphragm filter press consists of a motor reducer, gears, screws and firm nuts. When the filter press is pressed, the motor rotates forward to drive the reducer and gear, so that the screw is rotated in the firm nut, and the pressure plate is pushed to press the filter plate and the filter frame. When the pressure increases, the load current of the motor increases. When the current value set by the shield is reached, and the large pressure is reached, the motor blocks the power supply and prevents rotation, and the screws and nuts are reliable. The self-locking helix angle can reliably ensure the compression state in the process. When retracting, the motor reverses. When the pressure block on the plate is pressed, when the pressure reaches the limit switch, it will return to the stop position. In the long-term use of the filter press configuration, more or less will encounter the hydraulic oil after a period of time, the hydraulic oil seems to contain more impurities, or the hydraulic oil turns white, no adhesion and other signs, this is the result of emulsification hydraulic oil. According to our long-term acquaintance of hydraulic oil and some related tests. The emulsification of the hydraulic oil of the diaphragm filter press is the initial hydraulic oil containing a large amount of water molecules, and the resulting hydraulic oil is emulsified. In the ordinary work of a diaphragm filter press, there are several conditions for hydraulic oil to enter the water. One is that the filter press is used outdoors forever, with alternating cold and hot or every time it rains,

plus hydraulic oil. The tight parts of the flow path of the sealing components such as pipelines, hydraulic chambers, and oil pump stations are gradually aging and maintained over time. This may cause a small amount of water molecules to enter the oil pump station, and water molecules enter the oil pump station to fight the hydraulic oil. At times, over time, water is suspended in the hydraulic oil along with a large amount of water. At this time, as long as the electric motor in the pumping station is convulsed, the hydraulic chamber is squeezed by high pressure, and the water mass is quickly analyzed into water molecules, and is evenly evacuated around the hydraulic oil molecules. After a period of oxidative deterioration, the hydraulic oil will gradually become white, and the impurities will not be subjected to great pressure. The original volume is connected in the environment, and the gap between molecules is also larger.

When the oil pump is pumped into such a hydraulic oil chamber and pressure is applied to the piston, the force between the objects is mutual, so the piston will exert the same force as the hydraulic oil, and the hydraulic oil of the filter will gradually change when pressed . At the same time, it will lower the pressure of the filter press. This is why the hydraulic oil after water supply can only provide small pressure to the filter press. In the long-term use of the filter press configuration, more or less will encounter the hydraulic oil after a period of time, the hydraulic oil seems to contain more impurities, or the hydraulic oil turns white, no adhesion and other signs, which is the result of emulsification hydraulic oil.
