Installation of magnetic separator and matters needing attention
The magnetic separator is mainly composed of a shell, a drum, a guide plate, rubber roller, reducer etc.. It uses the magnetic adsorption principle, rely on the continuous rotation of the drum to remove iron and other magnetic metal powder.A new Xiang Yu think the installation process principle: adsorption of grinding fluid dirty along the guide plate through the rotation of the drum slowly, in a magnetic field, magnetic solid particles are magnetized, adsorbed on the outer surface of the drum, and taken out of the separation zone, after the rubber roller compacted by dehydration, the scraper is close to the scraping drum drum, along the guide chip board into slag car. The magnetic solid particles are separated, and some non-magnetic impurities are also removed. This series of magnetic separators are suitable for purifying emulsions, water base synthetic fluids and low viscosity cutting oils.
In grinding process, with the improvement of machining accuracy, high speed grinding and powerful grinding technology develop rapidly. Besides choosing reasonable grinding parameters, the circulation quality of grinding fluid must be improved. Purification device is divided into two types of filter and power type. The filter is used to remove impurities by filtration media such as filter screens, wire gaps, sheets, and paper tape filters. The separation of impurities by means of a force, such as centrifugal force, magnetic force, or gravity, such as a centrifugal, a vortex, and a magnetic separator.When grinding the ferromagnetic materials, there are both ferromagnetic and non ferromagnetic impurities in the waste liquid. The magnetic separator is usually used to remove more than 80% of the impurities. For better control of filtration accuracy, it is better to combine magnetic separators with tape filters.1 、 drive system and box separation, clean and convenient maintenance.2. The magnetic roller is magnetized evenly, the worn debris and iron powder are dried.3. Cooling liquid containing powder magnetic absorption impurities.4. The magnetic field produced is large and the adsorption area of stainless steel magnetic roller is large, and the separation effect is good.5, simple appearance, compact structure, smooth operation, low noise, small power loss.6 、 small size, easy to install and use, can be designed and manufactured according to the specific space of machine tools.
Magnetic separator installation should pay attention to matters, iron mouth auxiliary machine summed up the following points:1, according to the nameplate standard set flow assembly modeling, water inlet and outlet, if the machine does not match, you can change the change of joint changes.2, the direction of the machine before the normal operation of the situation, the bottom can be discharged, and then properly tighten the disc nut, so that the stick and magnetic barrels to reach the most rolling state.3, long hours do not work, should clean the box to prevent accumulation of impurities frozen, the chain clearance is too large, should be adjusted in time, elastic, regularly oiling the chain.4, the impurity cannot increase sharply, otherwise it will make the motor lock timely processing of rubber roller and magnetic attachments on the surface of the barrel.5 、 inspection and maintenance must be carried out before power or water.
