Because vacuum pump is often used in high temperature, high pressure, strong corrosion of the harsh environment, it is inevitable to have a variety of damage, we want to extend its service life, so that it can be used in various industries for a long time, it needs regular maintenance. In fact, the maintenance of vacuum pump is a troublesome thing. Many times, it will affect the future work if it is not handled in time. Let's see what the basic points of maintenance of vacuum pump are.
1. Never work with faults: when carrying out the maintenance of vacuum pump, there is another factor that we must pay attention to, that is, we must not let our equipment work with faults, because this will not only affect the work effect, but also may cause more serious consequences.
2. Master the basic maintenance requirements: each vacuum pump will have a very detailed maintenance instructions. Generally speaking, as long as people have problems with the vacuum pump, they should first compare the maintenance requirements of the equipment to find out whether they are doing the product maintenance poorly or not, resulting in a simple Faults, these faults, are generally in accordance with the instructions, can be handled very well, is also a very simple fault.
3. Contact after-sales service in time: if the failure of your own vacuum pump is a relatively large failure, which has seriously affected the failure effect, in this case, when carrying out vacuum pump maintenance, you must pay attention to contact your own after-sales service in time, and carry out maintenance under the professional guidance of after-sales service. Generally speaking, the after-sales service team All of them will arrange professional after-sales personnel in time for docking treatment, so this treatment is also very simple.
4. Electrochemical cleaning: put the metal parts to be cleaned in a certain solution, connect the parts to the positive or negative pole of the power supply, and then connect the plate made of a certain material to the other pole of the power supply, adjust the power supply voltage, obtain a certain current density, so as to achieve the purpose of removing oil and oxide layer on the surface of the metal.
5. Acid and alkali etching treatment: after degreasing, the etching treatment is carried out to remove the oxide on the metal surface. For the parts after heat treatment, the oil stain does not exist, so the etching treatment can be carried out directly to remove the annealed oxide layer. Generally, etching treatment is carried out in acid solution. Most metal oxides and metal itself can react with acid solution of appropriate concentration. Oxides react with acid to generate salt and water, while metals react with acid to generate salt and hydrogen. Part of hydrogen absorbed by metal surface will make some metals brittle. In order to avoid metal embrittlement and excessive corrosion, it can be used in etching solution Add inhibitor, and control the concentration and temperature of etching solution properly.
