High temperature weather is an important factor that affects the efficiency of equipment, as well as for filter presses. With the passage of time, summer is approaching. When facing the high temperature and heat in summer, what should users pay attention to when using the filter press? Su Dong believes that the most important thing to pay attention to at this time is the hydraulic system and filter plate of the filter press to protect against high temperature.
1. Hydraulic system: For hydraulic systems, whether it is a chamber filter press or a plate and frame filter press, this system is the most important part of the equipment, because it works the most frequently, and the number of extensions or retractions may be tens of thousands. Second; because the hydraulic system bears a lot of pressure on the filter plate from the equipment, and the pressure on the filter plate can often reach tens of MPa, so as the hydraulic oil in the hydraulic system, it is often the most stressed part. Need to bear the pressure of tens of megapascals. In this case, the temperature of the hydraulic oil will be relatively high under normal circumstances. In addition to the high temperature in summer, in these two cases, it can be said that it is adding fuel to the fire. The temperature will easily reach the limit of work, which often causes the hydraulic oil to evaporate. Because when the temperature of the hydraulic oil is high, the hydraulic oil is likely to evaporate and cause the hydraulic oil to decrease. This makes the oil volume less stable. The volume of the hydraulic oil changes with the pressure received, which is often easy It is not easy for the pressure of the equipment to meet the pressure requirements during normal operation, so it is urgent to do a good job of preventing high temperature.
2. Filter plate: Under direct sunlight and high temperature, the filter plate will be oxidized faster when exposed to direct sunlight. Especially the filter plate on the plate and frame filter press. The filter plate of some filter press equipment is made of polypropylene plastic material, that is to say, plastic material, so when exposed to direct sunlight, it will cause oxygen molecules in the air and filter The plate material changes, and the plastic filter plate is oxidized and deteriorated, becoming hard and brittle. In this case, the filter plate is easily damaged, which will eventually increase the cost of the filter press equipment. Therefore, the filter plate must be protected from high temperatures.
Therefore, when the filter press is used in hot weather in summer, special attention should be paid to the hydraulic system and filter plate of the filter press. It is necessary to avoid direct sunlight and perform relevant cooling protection work to ensure that the filter press is normal. jobs.
