Buy Base Oil N70
With the growth and development of industries, the need for base oils to make all kinds of grease, motor oils and hydraulic oils is more noticeable than ever. The oil refining companies also choose the appropriate solutions according to this need. Products that are based on customer needs and meet their needs. Blackwater company is one of the leading and technological companies in this field. Today we are going to talk about one of these products of this company. base oil N70.
What is Base Oil N70?
Base Oil N70 is considered among the base oils of group two. The low viscosity, good antioxidant property, shear stability and anti-corrosion properties of this oil have made it a very economical option for the production of additive oils. Due to its characteristics, this product is used in the production of a wide range of oils. From hydraulic oils for power transmission to compressor oils for wind compressors and refrigerator compressors. After refining with solvent, this oil is purified by the hydrocracking process.
Hydrocracking is a complex process that refines crude oil to convert it into oil. The resulting oil may not have the required specifications, so in order to reach the ideal state, the oil goes to the laboratories to add the necessary additives.
Specification of Base Oil N70
The most key specification of any oil are:
- Viscosity at different temperatures
- The amount of sulfur in the oil
- Viscosity index
- pour point
- flash point

Application of Base Oil N70
So far, you have learned about the extraction method and characteristics of N70 oil. By examining the characteristics of this oil, it can be seen that this oil has the ability to transmit power and be fluid at low temperatures and has anti-wear properties. More specifically, this oil is used in air compressors, refrigerator compressors and machining devices such as CNC machines.
1- Base Oil N70 in air compressor
Wind compressors are divided into three categories based on the mechanism of operation: rotary, screw and piston (reciprocating). In the following, we will examine the use of N70 oil in each of these compressors.
(A) Rotary compressor:
In rotary compressors, the high rotation of the rotor to compress the suction air causes the wear of the rotor itself and the surface of the housing. N70 oil is used to lubricate the bearings, shafts and prevent the wear of the rotor and the surface of the housing.
(B) Screw compressors:
Geared rotor shafts are used in these compressors. In this type of compressors, the air is continuously compressed; this makes the compressor no longer vibrate like a piston compressor. In this device, the oil plays a role in three stages: first, in the lubrication and prevention of wear between the rotors, bearings, and filters, the second, for the cooling of the compressed air by the rotors, which has a very high temperature Compressor capacity. A small hydraulic pump reduces or enlarges the air chamber by pumping oil, which can adjust the compressor capacity.
(C) piston compressors (Reciprocating):
In these compressors, when the piston goes down, the outside air is sucked into the cylinder. After suction, the inlet valve is closed and the piston condenses the air. When the air has the highest density, the outlet valve is opened and the air is transferred out under pressure. N70 base oil in this system seals the pores and seams so that dense air does not escape from inside the cylinder. Also, with the oil flowing around the cylinder, the piston is cooled, which has a great effect on the efficiency of the device.
2- Base Oil N70 in refrigerator compressors
Refrigerator compressors are mostly piston compressors that condense air. High temperature for a long period of time reduces efficiency. The oil in this system is responsible for reducing the temperature inside the compressor. It also reduces corrosion and rusting of internal oil components. Also, in the long term, dust may enter the compressor through the seams and cracks. Compressor oil prevents this by sealing the gaps.
3- Base Oil N70 as a fluid for machining devices
Machining machines are used for cutting, shaping and changing the physical structure of metals. During cutting, the friction between the tip of the machine and the piece of metal is very high and generates heat. This problem makes the process of shaping and cutting not easy and the part does not get the desired shape. A lot of heat caused by friction causes a lot of damage to the device in the long run.
