Diaphragm filter presses are widely used in the industry. Hydraulic oil is an indispensable and important element in the use of filter presses. Hydraulic oil products are good or bad, and there are still some subtle effects of different products on filter presses. Differences, the following are three research questions about hydraulic oil to help you better understand the knowledge of hydraulic oil.
Question 1. What type of hydraulic oil should be selected for diaphragm filter press equipment?
Answer: Because filter press equipment is a kind of equipment that is used all year round, and it is a long-term high-frequency work, so filter press equipment is more frequent and workload than other equipment. It must be large, and when the filter press equipment is running, the hydraulic system must provide a pressure of 20 MPa. Since such a high pressure, the hydraulic oil used on the equipment must be a high-resistance type of hydraulic pressure. In addition, considering that the equipment is used throughout the year, and among the changing factors in the year, the temperature factor has the most prominent impact on the hydraulic oil of the equipment. When the temperature of the hydraulic oil is too high, we can take some simple methods. To reduce the problem, and when the temperature is too low to cause the hydraulic oil to solidify, we are in more trouble, so the hydraulic oil type is selected to be a low temperature type. In short, the hydraulic oil of the filter press equipment adopts the low temperature and high resistance type.
Question 2. Why does the hydraulic oil decrease?
Answer: It seems that the hydraulic oil is stored in a relatively closed hydraulic system and should not be reduced. In fact, the hydraulic oil will gradually decrease. The diaphragm filter press is in operation. Because it needs to generate a lot of power, the internal pressure of the hydraulic oil is also very large. When some parts of the hydraulic system have weak pressure bearing capacity, they will overflow in the form of gas. The most obvious place is the hydraulic pressure. The screw of the system, because of its repeated extension or retraction, will bring some hydraulic oil on the wall of the screw, so that the hydraulic oil is naturally reduced.
Question 3. How do impurities in hydraulic oil come from?
Answer: After the diaphragm filter press has been used for a period of time, the hydraulic oil will become cloudy and even emit a peculiar smell. This is because the hydraulic oil contains a lot of impurities. This is because the impurities are caused by the hydraulic oil when the hydraulic oil circulates in the hydraulic system. The substance produced by the wear of each component and the oil body, this substance is deposited in the oil tank with the liquid circulation, which produces impurities in the hydraulic oil. When the hydraulic oil has a foul smell, it is because the equipment is overloaded during operation. It is caused by the “burning” of impurities.
