Lubricating Oil Vacuum Oil Filter  



I. Overview of SDLY Transformer Vacuum Oil Filter/Insulating Oil Filter/Qualified Instrument Rental/Equipment Leasing

To meet the needs of on-site maintenance of various high and low voltage oil-filled equipment in power maintenance departments, we refer to the technology of Yangzhou Dario Company, strictly implement national standards, and are guided by DL/T521-2004 Guidelines for the Use of Vacuum Oil Purifiers. We have designed a product with features such as small size, light weight, easy mobility, low noise, long continuous operation time, stable performance, and convenient operation. It is an ideal equipment for filtering water, gas, and impurities from transformer oil, turbine oil, machine oil, hydraulic oil, and other oil liquids in power plants, substations, transformer stations, electrical manufacturing plants, and industrial and mining enterprises.

II. Main Uses of SDLY Transformer Vacuum Oil Filter/Insulating Oil Filter/Qualified Instrument Rental/Equipment Leasing

1. This machine can be used for on-site oil filtration and oil replenishment of various oil-immersed transformers, oil-immersed current transformers, voltage transformers, and low-oil circuit breakers.

2. This machine can be used for on-site hot oil circulation drying of the above equipment, especially effective for hot oil circulation drying of oil-immersed current transformers, voltage transformers, and low-oil circuit breakers.

3. This machine can be used for on-site vacuum oil filling and oil replenishment of sealed oil-immersed equipment, as well as vacuuming the equipment.

4. This machine can also be used for regeneration and purification of slightly deteriorated transformer oil, making its performance meet the standard for qualified oil.

III. Main Features of SDLY Transformer Vacuum Oil Filtration Machine/Insulating Oil Filter/Qualified Instrument Rental/Equipment Leasing

Compared with similar products at home and abroad, this machine has the following features:

1. Small size and light weight, being half the weight of similar products.

2. Improved and perfected the design of oil-gas separation. Using vacuum oil inlet, a tubular rotating oil sprayer is installed, which reduces resistance, increases rotation speed, and enhances the oil-gas separation effect.

3. According to user needs, the filtering medium of the oil purifier part is a specially made fine filter element, which is a tubular filter element made of odorless polypropylene through melting, injection, traction, and receiving molding.

4. Multi-function in one machine is an important feature of this machine. Since this machine is used on-site and utilizes the original oil-filled equipment as the oil storage tank, hot oil circulates between the machine and the equipment, allowing the three functions of oil filtration, regeneration, and hot oil circulation drying to be carried out simultaneously, saving labor and time, truly achieving three benefits at once.

IV. Working Principle of SDLY Transformer Vacuum Oil Filter/Insulating Oil Filter/Qualified Instrument Rental/Equipment Leasing

The vacuum oil purifier is designed based on the different boiling points of water and oil. It consists of a vacuum heating tank, fine filter, condenser, primary filter, water tank, vacuum pump, oil discharge pump, and electrical cabinet. The vacuum pump extracts air from the vacuum tank to create a vacuum. Under atmospheric pressure, external oil enters through the inlet pipe into the primary filter to remove larger particles, then enters the heating tank. After being heated to 40-75°C, the oil passes through an automatic oil float valve, which automatically controls the balance of oil entering and leaving the vacuum tank. The heated oil is rapidly rotated by spray wings to separate into a semi-mist state, where water in the oil rapidly evaporates into water vapor and is continuously drawn by the vacuum pump into the condenser. The water vapor entering the condenser is cooled and then returned to water for discharge. The oil in the vacuum heating tank is discharged by the oil discharge pump into the fine filter, where particulate impurities are filtered out through the filter element. This completes the entire process of the vacuum oil filter rapidly removing impurities, water, and gas from the oil, and clean oil is discharged from the outlet.

V. Operating Instructions for SDLY Transformer Vacuum Oil Filter/Insulating Oil Filter/Qualified Instrument Rental/Equipment Leasing

1. Connect the oil inlet and outlet pipes properly, and close all valves.

2. Connect the three-phase four-wire power supply according to the total power of the machine. Press the "Vacuum On" button to make the vacuum pump and oil pump rotate in the direction indicated by the arrows. Connect the safety ground wire, check that all circuits are reliably connected, and that all oil circuit valves are open. Jog the vacuum pump, oil inlet pump, and oil discharge pump to ensure there is no jamming or eccentric vibration. For models with a condenser, inject tap water into the water storage chamber through the drain valve. After confirming everything is ready, proceed with the operation procedure.

3. First start the vacuum pump. When the vacuum gauge reaches a negative pressure of -0.08MPa, open the oil inlet valve to allow oil to enter until the oil level in the vacuum tank reaches the middle line of the oil level gauge (be careful not to suck oil into the vacuum pump, otherwise the equipment cannot operate normally; if oil is accidentally sucked into the vacuum pump, promptly drain the oil from the vacuum pump and add appropriate vacuum oil). Then open the oil discharge valve before starting the oil discharge pump switch. The filtration and regeneration functions of this machine can be selected arbitrarily by switching the ball valve. Start oil discharge and filtration of impurities to make the oil circuit circulate normally;
