V. Main Control Systems Of YELOCO Transformer oil filtering machine

1. Heating control system with Constant temperature:

The constant temperature heating control system consists of a programmable controller PLC, heater R, temperature sensor, etc. The PLC sends out a logic command through internal program calculation based on signals collected by the temperature sensor: when the temperature is lower than the set temperature, the heater R will start to work under the control of the PLC; when the temperature reaches the set temperature, the heater R will stop working based on the control of PLC; the above work will be repeated until the temperature is reduced below the lower limit set temperature, and thus the constant temperature heating control function is realized.

2. Automatic liquid level control system:

The automatic liquid level control system consists of a programmable controller PLC, a medium liquid level switch and an electromagnetic valve. The PLC sends a logic command through an internal program based on the liquid level signal collected by the medium liquid level switch: when the oil level is lower than the medium liquid level switch, the electromagnetic valve will start to work in a delayed manner; When the oil level reaches or exceeds the medium level switch, the solenoid valve will stop working immediately. Thus, the function of automatic liquid level control is realized repeatedly.

3. Over-pressure protection system:

The over-pressure protection system consists of a programmable controller PLC and a pressure switch P. The PLC sends out a logic command through an internal program based on the pressure signal collected by the pressure switch P. When the pressure exceeds a set value, the PLC will immediately send out an alarm signal and stop the product at the same time.

4. Oil injection protection system:

The oil injection protection system consists of a programmable controller PLC and a high liquid level switch. The PLC sends out a logic command through an internal program based on the liquid level signal collected by the high liquid level switch. When the high liquid level reaches, the PLC will immediately send out an alarm signal and stop the product at the same time.

5. Overload protection system:

The overload protection system consists of a programmable controller PLC, a motor protector QRF and a frequency converter VFF. The PLC collects an overload signal through the motor protector or the frequency converter and sends out a logic command through an internal program. When the overload signal is valid, the PLC will send out an alarm signal and stop the product immediately.

VI. How to Operate YELOCO Transformer oil filtering machine?

VII. How to Maintenance YELOCO Transformer oil filtering machine?

When the vacuum pump is operating, the oil indicator must be closely monitored to have a firsthand information about the oil fluid condition. (the oil fluid shall be on the oil indicator line) When the water content in the vacuum pump oil is slightly on the high side, it must be immediately changed. (use the specialized vacuum pump oil, to decide on the renewal based on the visual inspection on the degree of contamination in the vacuum pump oil; if found to be degenerative and emulsified, it must be immediately changed) When there is a huge amount of water in the cooling device during operation, it must be instantly drained out.

2. The ever changing condition of the pressure values must be closely monitored at all times. When the pressure gauge is more than 0.35 Mpa, the filtering device must be washed and cleaned thoroughly or the filtering components must be changed; The primary filter and fine filter must be regularly removed and cleaned thoroughly to maintain adequate cleanliness in order to avoid blockages and cause the inadequacy in the oil input or the frequent operations of the oil pump.
3. For every 5,000 hours of operation, appropriate lubricants must be supplemented in order to prevent the overheating of the power equipment.
4. Regularly conduct checks on the operational conditions of the oil pump and the vacuum pump to avoid the sudden cessation of the equipment or severe condition of overheating. (refer to the user manuals of the oil pump and the vacuum pump)
5. After a certain period of operation for the equipment, conduct regular checks on the safety and reliability of the control system, the sensitivity and reliability of the temperature control device, the hardening effect of the seals in the pump shaft (leakage), the no blockage phenomenon of the piping system, the normal functionality on the pump and the related noise in the equipment. In the situation where the equipment has stopped operation for 1 month and above, this equipment shall be placed in a dry environment with its cabinet door properly closed and its main body suitably covered.
6. When the equipment is not operated, the residual oil shall be drained out completely.

Turbine oil purifier machine: The Ultimate Buying Guide

Chapter 1: Why need Turbine Oil Purifier machine?

The oil used for regulation and lubrication system of turbo-generator unit will be mixed with steam, water or impurities to different degrees during operation, which needs frequent maintenance and treatment, otherwise it may accelerate the deterioration of oil quality or cause the failure of regulation and protection system and the damage of bearing bush, thus affecting the safe operation of the unit.

Hazards of water, gas and impurities in turbine oil:

The oil is rapidly oxidized and deteriorated to generate acidic substances, which corrodes the metal contact surface;
Precipitation failure of additives in oil, reduction of lubricating film thickness and aggravation of mechanical wear;
The insulation performance of oil decreases, the dielectric loss increases, and methane, acetylene and hydrogen increase;
Lubrication, cooling and flow reduction accelerate metal surface fatigue;
Ice crystals formed at low temperature block the components and reduce the rigidity of the system;
Slow response of the system accompanied by irregular action conduction performance reduction;
High oil temperature can not play a cooling role;
The oil transfer pump and power equipment are damaged due to gas etching;

YELOCO Turbine Oil Purifier Machine, it can not only effectively remove gas, water and impurities in the oil, but also automatically demulsify, so as to achieve the real effect of purifying steam turbine oil. It improves the quality of oil products, ensures the normal operation of the regulation and lubrication system of the turbine units, and prolongs the maintenance cycle of the turbine units.

Chapter 2: Benefits of a Turbine Oil Purifier machine

1) Strong capabilities in filtering water less than 50PPM.

2) Fast demulsification less than 8 min.

3) Strong performance in purifying impurities less than 1 micron.

4) Excellent functions in removing gases less than 0.1%.

5) Advanced medium cooling and endothermic condensation system.

The YH-TY series Turbine oil purifier machine is especially adaptable and suitable for handling turbine oil, hydraulic oil, refrigeration oil and other lubricating oils that require huge amount of water elimination and precise filtering functions.

Chapter 3: Parts of a Turbine Oil Purifier machine

Chapter 4: How to operate Turbine Oil Purifier machine?

(1) Basic operation of start:

1) Open and close the relevant valves in accordance with the valve status function table, so that the oil circuit ( Oil inlet → Oil inlet valve → Primary filter → Heater → Water distributor (Trap)→ Oil supply solenoid valve → Vacuum separator → Oil pump → Secondary filter → Fine filter → Oil outlet valve → Oil outlet) is unblocked. Open oil inlet valve 1, oil outlet valve 12, block valve 4, block valve 5 and block valve 16. Close drain valve 2, bypass valve 3, bypass valve 9, circulation valve 10, air leakage valve 14, air leakage valve 17 and sampling valve 11, blowdown valve 18, air permeability valve 6, blowdown valve 7, blowdown valve 13 on the pipeline.

2) Switch the air switch QF and control switch QF1, and the power on indicator lamp HL on the panel is on.

3) Start the vacuum pump to start working, and the vacuum pump running indicator lamp is on.

4) The system starts to feed oil under the action of the oil inlet pump. When the oil enters the vacuum separator and reaches the control point of the upper liquid level, the oil pump will be automatically opened by sending a signal and the operation indicator lamp of the oil pump will be on at the same time.

5) Slightly open or close the control valve (outlet valve 12, inlet valve 1, circulation valve 10, bypass valve 3, bypass valve 9) in accordance with the specific conditions of working conditions to ensure the basic balance of oil inlet and outlet. That is to say, the oil level in the vacuum separator is always kept between the upper and lower liquid level gauge to avoid frequent start and stop of the oil pump; The circulation valve can be opened properly to reduce the pressure when the oil pressure is too high.

6) After the operation of vacuum pump and exhaust oil pump, if the oil temperature is lower than the set value of the temperature controller, the heater will be heated only after the heating knob is opened, and the heating indicator lamp is on at the same time.

7) In case of emergency during operation, press the emergency stop button SBE immediately to stop the machine; If you need to resume work, turn the emergency stop button left to reset, and the machine will start working again.

8) Observe the working condition of the vacuum separator at any time. If there is a large amount of foam in the vacuum separator due to the high moisture content of the oil, when the foam exceeds the liquid level gauge, the gas ballast valve shall be properly opened and the vacuum degree in the vacuum separator shall be maintained at about -0.085 MPa. Reduce the vacuum to eliminate foam, avoid oil spill, and close the gas ballast valve after the foam is removed.

9) The machine has a foam sensor. When the foam sensor senses the foam in the vacuum separator, it will automatically open the air permeating solenoid valve for defoaming. If there is still induction within the time set by the time relay (generally set to 0.5 s, see the attached figure, the setting of time relay), the machine will stop and alarm.

10) During the operation of the machine, personnel shall inspect the equipment, and the inspection period shall not be less than 30 minutes each time.

(2) Basic operation of Shutdown:

1) When the oil treatment is completed or the operation needs to be stopped

2) First, turn off the heating through the heater knob switch. After the oil purifier continues to run for 3-5 minutes, close the oil inlet valve.

3) Turn off the vacuum pump and stop vacuuming the machine.

4) Drain the oil in the vacuum separator through the oil pump, and then turn off the oil pump.

5) Close the inlet and outlet valves after the machine stops.

Chapter 6: Transformer Oil Filtering machine use tips

These tips are used for all kinds of vacuum Transformer Oil Purifier machines. As a long-established brand in China, YELOCO, an oil filtration machine company, has had over 20 years of industrial credibility and integrity. The following tips will help you operate the vacuum Oil Purifier machine correctly and increase the life of not only the Transformer but also the oil.

Oil can only be circulated inside the transformer at 1,500 l/per hour. You can open ¾ of the oil outlet valve as well as the machine circulation valve to control oil flow capacity when you are filling oil into the Transformer.
Transfer of oil from one tank to another tank can be done at more than 1,500 L/per hour.
Oil should be circulated through machine filters more than once (twice is preferred) for better cleaning.
Oil should not be heated above 60 degrees Celsius. The maximum suggested temperature is 65 degrees.
If the oil going into the vacuum chamber is too hot, it will boil and overflow. Therefore, YELOCO sets the machine heating temperature to 60 degrees Celsius.
Oil going into the machine should be restricted at the source so that it prevents the machine from over-filling. This would mean that the machine vacuum chamber volume must match machine flow capacity. YELOCO Oil Purifier Machine’s design and make it according to these scientific ratios.
Dirty oil will need to be circulated slower so that the machine can withdraw moisture and prevent machine overflowing.

Chapter 7: How to package the Transformer Oil Filtration?

Why are tin cases used? Well take a look at the following advantages:

Iron box packaging acts as an excellent barrier and provides comprehensive protective properties to the machine. These packaging materials have extremely low (almost zero) permeability to gas, water, and water vapor, good fragrance retention, and are completely opaque and effective. The same properties also avoid the harmful effects of ultraviolet rays from permeating inside the package. Plastics and paper packages do not match these properties for transporting and carrying such huge machines. Therefore, iron box packaging can provide excellent protection for the contents and is conducive to maintaining the quality of the goods for a long time.

Iron box packaging has good mechanical properties and carries high strength. This type of packaging also has good ductility and high strength. They can be processed by stamping, rolling, stretching, welding, etc., and can be made into thin walls. Packaging containers that have high compressive strength and are not easily damaged and can also be combined with other materials to form composite packaging materials with excellent comprehensive performance.

The packaging is convenient and hygienic. Its containers and internal coatings can generally meet the requirements of hygiene and safety and can adapt to different climatic conditions. The waste from this packaging is better treated and can be recycled.
