What is hydraulic oil filtration machine?

ZJC series hydraulic oil filter machine is mainly designed to purify various industrial waste oils with the viscosity less than 320 mm2/s, such as turbine oil, mechanical oil, hydraulic oil, compressor oil and refrigeration oil, etc. which contaminated by water infiltration, emulsification and mechanical particles during processing, transportation and application. It would be ideal choice for plant maintenance service for energy saving and cost reduction.

As a hydraulic oil filtration machine manufacturer, YUNENG has a professional technical team, including 14 R&D engineers, 9 after-sales service engineers, and professional maintenance and troubleshooting engineers who can go abroad for installation and debugging.

In addition to hydraulic oil purifiers, YUNENG also provides turbine oil purifierlube oil purification machine and other oil filters.

Features of Hydraulic Oil Cleaning Machine:

  1. Suitable for voltage grade ≤320 mm2/s industrial oil.
  2. Compact in structure, simple in operation.
  3. Convenient in maintenance, low cost.

How hydraulic oil filtration is done?:

  1. When the ZJC series hydraulic oil filtration unit works, the oil to be filtered enters the electric heater under the action of the external atmospheric pressure and the suction vacuum of the oil filter in the vacuum pump. The heated oil passes through the strong magnetic filter, and the metal particles and large particle impurities are filtered.
  2. In addition, the oil-containing fine impurities enter the second and third stage filters, and is filtered again to remove the impurity oil into the three-dimensional vacuum flash tower. Under the action of the spray device, the oil is dispersed into a mist and sprayed.
  3. On the three-dimensional flashing pall ring, a very thin oil film (thickness of 0.025mm) is formed, and the oil film curve moves downward, resulting in a large aeration area and aeration time retention process, thereby performing full demulsification, separation process of dehydration and degassing. 
  4. The mixed gas formed by vaporized water vapor, light hydrocarbon or the like enters the water gas separation device, the strong air condensation system, and the vacuum buffer chamber, and rapidly cools the water vapor, the light hydrocarbon, etc., and the condensable gas and the water vapor condense into the water is discharged through the drain. The non-condensable gas is discharged through a vacuum pump. The oil that removes moisture, gas and mechanical impurities enters the precision filter through the oil pump, and the particulate impurities in the oil are filtered to purify the clean oil to complete the entire oil purification process.

Why do we need hydraulic oil purifier?

In the process of using construction machinery and equipment, hydraulic systems are generally used to control and manage the equipment, so the quality of hydraulic oil is very important. Under normal circumstances, the hydraulic system should be subjected to a load test before the process of equipment control, which will contaminate the hydraulic oil in the hydraulic system during use. If the hydraulic oil is polluted during use, it will adversely affect the normal operation of the entire construction machinery and equipment.

In order to solve the pollution problem of hydraulic oil, we can use hydraulic oil filtration machines to filter and purify hydraulic oil.

Sources of Hydraulic Oil Contamination

There are many reasons for oil pollution during the operation of the hydraulic system of construction machinery and equipment. It can be mainly divided into three aspects:

1. Internal generation

During the operation of mechanical equipment, the hydraulic system generates heat due to the influence of pressure, which greatly increases the temperature in the hydraulic system. Hydraulic fluids oxidize when heated, producing organic substances that corrode the metal components of machinery. In the process of long-term oxidation and wear, the performance of construction machinery and equipment will be greatly reduced.

2. System Residues

Hydraulic oil has good water absorption in the process of practical application. If the hydraulic system is in normal operation, the moisture in the air enters the hydraulic system, and after the construction machinery and equipment stop working, the temperature in the hydraulic system will drop, which will lead to the fusion of water molecules and hydraulic oil. This will have a certain impact on the quality of the hydraulic oil.

3. The outside world enters

During the processing and assembly of construction machinery components, it is also easy to mix some external impurities into the hydraulic system, which reduces the performance of hydraulic oil in all aspects.
