Hydraulic oil vacuum filter is how to separate oil and water? The vacuum filter does not simply rely on filtration to separate the oil and water, but also to heat the oil and water mixture. In order to avoid the oxidation of hydraulic oil at high temperature, vacuum is needed. The purpose is to reduce the boiling point of water, so that the water in the oil will boil at more than 70 degrees and evaporate, so as to achieve the purpose of oil-water separation without damaging the hydraulic oil.
Is the tap water filter really useful? Strictly speaking, if it is harmful to people and uses pure water for a long time, some trace elements of the human body cannot be supplemented to people, which is harmful to people. as long as tap water is not consumed directly, it can meet the hygiene requirements, however, some experts are alarmist and it is more useful to take the opportunity to sell filters. It is mainly used to remove impurities such as sediment and large particles carried by tap water through pipeline transportation. At present, I personally feel that hanshill is currently a relatively good domestic filter, and their machines are imported from Germany, and the reputation in the front is very good. 1. now the water pollution is very serious. the tap water in many areas is clean when it leaves the factory. yes, but the possibility of secondary pollution during transportation is very high. 2. it is good to have sediment and rust. in some places, tap water will smell different or yellow, which is a si
