Harm and treatment of turbine oil after emulsification

2020/1/19??????view:

  1、 What is turbine oil?

  Turbine oil, also known as turbine oil, is mainly used for power plant steam turbine, hydropower station water turbine generator and other lubrication occasions requiring deep refined lubricating oil. Turbine oil is a kind of oil used in turbine engine, which is suitable for high-speed machinery lubrication and mainly plays the role of lubrication, heat dissipation, cooling and speed regulation. According to the national standard gb11120-89, the demulsification value of turbine oil shall conform to: demulsification value (40-37-3) ml: no more than 15 min (at 54 ℃).

  2、 Parameter value of turbine oil after emulsification.

  There are three reasons for the emulsification of turbine oil: water content, emulsifier and high-speed mixing. Water is the main cause of oil emulsification.

  (1) The oil film may be damaged when water is separated from other places

  (2) Emulsion can cause corrosion of metals

  (3) The emulsion is deposited in the circulating system, hindering the circulation of oil, causing insufficient oil supply and failure

  (4) When the oil is emulsified, it is easy to cause oil aging. Naphthenic acid soap, gum and other substances produced after aging belong to emulsifier, thus accelerating oil emulsification

  (5) The emulsified oil reduces the lubricating effect of turbine oil, increases the friction of various parts, causes overheating of bearings and damages the parts.

  3、 The harmful phenomenon of turbine oil after emulsification.

  After the turbine oil is emulsified, it may cause the following hazards:

  (1) The oil film may be damaged when the water is separated from other places;

  (2) Emulsion can cause corrosion of metals;

  (3) The emulsion is deposited in the circulating system, which hinders the circulation of oil, causes the shortage of oil supply and causes faults;

  (4) When the oil is emulsified, it is easy to cause oil aging. After aging, naphthenic acid soap, gum and other substances are all emulsifiers, thus accelerating oil emulsification;

  (5) The emulsified oil reduces the lubricating effect of turbine oil, increases the friction of all parts, causes overheating of bearings and damages the parts;

  (6) The emulsification of turbine oil can accelerate the oxidation of turbine oil, increase the acid value and produce more oxidation deposits, thus further prolonging the demulsification time of turbine oil.

  4、 How to improve the demulsibility of turbine oil and the effect of purification and dehydration.

  If water enters the system, the oil begins to age. When it is found that the anti emulsification degree of the oil is poor, the medium clean brand filter oil regeneration equipment (ZJ series or zj-z series turbine lubricating oil purification device) shall be put into operation in time to remove the aging products in the oil, such as naphthenic acid soap, gum and other aging products, so as to improve the anti emulsification of the oil.

  In addition, it can also add (10-20) × 10 demulsifier, such as GPE15S-2 (polyoxyethylene polyoxypropylene glycerin stearate), which is also helpful for demulsification of oil products.

  Avoiding the emulsification of turbine oil plays an important role in ensuring the safe operation of the turbine. The key to solve the emulsification problem of turbine oil is to strictly control the product design, manufacture, installation, operation and maintenance, as well as the quality of turbine oil.
