The Steam Turbine and protective actions are based on oil as the working medium, support bearings and thrust bearings also requires a lot of oil to the lubrication and cooling. Therefore, turbine lubrication system, fuel system, control system and protection systems are closely linked together to form the turbine oil system, turbine generator sets to ensure the normal operation.

 The turbine oil system can be divided into two groups according to conditions. The first group is the low-pressure oil system, lubrication system including oil pipelines, electricity supply to pump hydraulic oil pipe coupling and hydrogen-cooled generator seal oil pipeline system, the general system of hydraulic oil does not exceed 0.3MPa. The conditioning system and the second group of oil pipeline protection systems. In this system, adjust the pulse to pass the oil is medium, but also the hydraulic servo of the working media, change the hydraulic system depends on the power turbine, parameters and characteristics of the unit structure. The small and medium-capacity hydraulic pump for the main steam turbine 0.49-0.98MPa, with the increase in unit volume and increased steam parameters, the hydraulic control system will be further enhanced.

The pressure lubrication system with a common discharge pipe and tubing, pressure tubing-conveyed from the turbine oil to each bearing, the bearing into the bearing oil depends on the temperature of operation by installation of a dedicated entrance on the bearing washer to adjust the different specifications.

The conditioning system and protection system consist of components and the corresponding adjustment of the composition of the oil pipeline, the oil pipeline into the pipeline and pulse power channels. The power equal to the main pipeline pump hydraulic oil pressure in the steam turbine normal conditions, the oil pressure is constant, only the load caused by the change transition process is an exception, this time as an instant increase in traffic, the pressure will force oil reduced. The conditioning system in the pulse hydraulic pipe with turbine load and working conditions and changes in the hydraulic system can automatically change with the adjustment can also be changed by means of manual-guided institutions. The protection system in pulse pressure in the turbine oil pipeline's normal operating condition is constant, when the protective device operation, this only changes the pulse hydraulic.

The turbine oil purifier is used for treating the unqualified turbine oil, especially the seriously emulsified turbine oil. This products, which can rapidly and effectively remove the water, gas and impurities, break emulsification. It aims at turbine oil’s nature of high water content, easy emulsifiable and high impurity content, and makes the oil recover the new oil's nature. 

1. Breaking emulsification thoroughly with high- molecule polymeric material.
2. Dewatering very effectively with once and for two steps dehydrating method. It can thoroughly clear away the liquid water, free water and 80% dissolved water. 
3.With distinctive removing impurities technique filtering through double FH trapezoidal network and absorbing by high polymer material, this machine can make the ß3 equal or surpass 200 and make the cleanness lower grade 6(NAS1638).
4.With the trapezoidal, spiral, automatic back flushing system.
5.With the advanced dielectric condensation devices.
6.On-line oil purification can be carried out with turbine or water turbine automatically without any person. 

Advantage:
This machine breaks emulsification thoroughly, and the oil is very difficult to emulsify again after treatment. Its dehydration volume is large and it can absorb water on line. TY series, which prevent lubrication system from damage, can effectively extend the lifetime of oil and protect turbine and other machines.

"What micron filter should be used to filter a 220 gear oil? We are looking into getting a filter cart to filter the oil while the machine is running."

First, determine the optimum target cleanliness level for that specific gearbox, and the do not forget to ensure adequate breathers are fitted, as any attempts at clean-up will be lost quickly. A few tips on filter carts:

First, ensure that for each type of lubricant in use, there is a dedicated filter cart to avoid cross contamination of fluids. 

Second, because this is fluid power generating device, ensure it complies with all the safety requirements and has a pressure venting safety valve in the event of dead-heading the pump. 

Third, ensure the cart includes a by-pass loop to the filters, and incorporates a sampling connector for the use of online instruments or bottle sampling. The design (pump and filter selection) of filter carts is dependent on two factors; the lubricant's viscosity grade, and the temperature at which the cart will be used. A higher viscosity, such as an ISO VG 220 oil, will require a lower flow rate in the pump to avoid high differential pressures across the filter. But this will be affected by the ambient and operating temperatures.

While the use of quick connectors allow the cart to be used while the gearbox is operating (this is the optimum filtering condition), the lubricant's viscosity will also be affected by the ambient temperatures, so if this is located outdoors, assume the worst case winter temperature when looking at the viscosity issue. Of course, slowing the flow rate to avoid high differential pressures will increase the time to filter the box, and depending on the Beta ratio, the rule of thumb is to allow the volume of the gearbox to circulate seven times through the filter for effective clean-up. For example, a gearbox with 50L sump capacity and a filter cart with a 10L/min flow rate will take five minutes for one pass and approximately 35 minutes to clean up. Keep in mind the flow rate versus the time available for filtering.

As to the filter rating, experience has shown a 10 micron filter capable of achieving better than ISO 17/15/12. However, if your optimum target cleanliness level is lower than this, consider a 6 micron filter. There are various ways to strike an optimum balance between flow rate and filter rating, and this includes the possibility of putting several filters in parallel to increase the flow area. As a simple guide, the differential pressure can be halved by doubling the length of the element or putting two elements in parallel. 3 micron filters will work with ISO VG 220 oils, but check the temperature conditions, and whether your target cleanliness levels require such fine filters. The cost of these elements should be considered.

If you recycle just two gallons of used oil it can generate enough electricity to run the average household for almost 24 hours.

Cars are an indispensable fact of life for most of us. So, too, are abundant and clean supplies of drinking water. What we do with the used oil from our cars plays an important role in balancing our desire for convenient transportation with our desire for a clean and healthy environment today and for future generations.

We are all familiar with recycling newspapers, aluminum cans, glass and plastic bottles, but you may not be aware of the efforts of the petroleum industry and other groups to promote used motor oil recycling: providing convenient collection sites for the purpose of keeping used motor oil out of our waterways and ground water supplies and getting used oil into the recycling system.

Motor oil has value even after it has been drained from an engine. The oil you take to a collection center to be recycled saves energy. It can be reprocessed and used in furnaces for heat or in power plants to generate electricity for homes, schools, and businesses. It can also be sent to a refinery that specializes in processing used oil and re-refined into lubricating base oils that can be used to formulate engine oils meeting API specifications.

What can you do? If you change your own oil, be certain that you take it to a collection center for recycling. If you take your car to an automotive service outlet, you can be fairly certain that they recycle the oil that they change. But if you're not sure, ask.

Used motor oil that is collected by "do-it-yourselfers" is critical to the used oil recycling system. Next time you change your own oil, remember, you can make a difference by recycling the oil from your car, truck, motorcycle, boat, recreational vehicle or lawnmower. By dropping off your used motor oil today you help prevent pollution and conserve energy for a safer and healthier tomorrow.
