Power transmission utilizing a hydraulic system has wide range of applications in automotive, construction and industrial machinery. It is used in systems where multiplication of force is required as well as in a system where accurate and reliable controls are provided. Hydraulic oils are used as media in hydraulic system and play a crucial role in the functioning of hydraulic systems. Lodha Petro range of high performance hydraulic fluids ensure that your hydraulic systems work at peak performance even under the toughest conditions. Lodha Petro has developed the following grades that meet three different performance levels:
Lodha Hydrol- used for equipments running under moderate conditions.
Lodha Hydrol HLP- to be used for machinery operated under critical conditions Lodha Ultimo- to be used where broad operating temperature range is expected.
Lodha Safefluid series to be used in high temperature areas where fire hazards becomes a risk factor for the machine to perform.
Mould oils are manufactured from selected base oils or from refined petroleum product and fortified with special additives depending on the application. Shuttering oil is specially formulated for the construction industry, which provide god surface finish to the concrete.
Thermic fluids are meant for transferring the heat energy from source to receptor. Application of heat to a system or process may be direct (by using a flame or electric heater) or indirect using a circulating fluid with a separate heater. Indirect heating offers the prominent advantages such as:
Absence of hot spots
Central heat source can be used to meet the several heat requirements of different processes.
Thermic fluid is a medium used in indirect well controlled heat transfer system used in industry. These oils have high specific heat and better thermal conductivity up to operating temperature and provide rapid heating and greater flexibility in heat transfer systems.
Lodha power turbo grades are premium quality turbine oils made from paraffnic base stocks having excellent oxidation and thermal stability. These properties are further enhanced by selected additives. Turbine lube oil systems have many missions. Among the most important: cooling bearings, flushing contaminants away from rotating parts, providing hydrostatic lift for shafts, actuating valves in the hydraulic circuit, and coating and lubricating the system internals. Formulating lubricants capable of performing all these tasks well is a difficult job, one that must consider the impacts of large temperature fluctuations and ingress of contaminants such as dirt and water, as well as other physical and chemical challenges.
With time since the specifications set by turbine manufacturers have been amended with the changes in design, turbine oils have undergone several advancements. Turbine oils must now simultaneously meet the requirements of both steam and gas turbines. Improvements in base oil refining technologies provide more thermally stable and oxidatively robust products. Coupled with improvements in additive chemistries, modern turbine oils represent a delicate blend of lubrication science.
Compressors are used in operations requiring compressed air. It is essential to operate compressors without any pressure loss. Lodha compressor oils meet the requirement of high performance and specifically designed compressor machines. This ensures compressors to operate with greater reliability in today's tough conditions. Power compressor oils are recommended for lubrication of heavy duty reciprocating and rotary air compressors.
Gears are mechanical devices used for transmission of mechanical power and motion. The main function of gear oil is to reduce friction and power consumption. The application criteria set by the gear box manufacturers demand the gear oil not only to perform in adverse conditions like high temperature, lower sump size, low clearance between shaft and gear teeth etc. but also maintain It's properties in high temperature and heavy load conditions. Industrial gears are of two types, enclosed and open.
The enclosed gears are lubricated by splash lubrication or a pressure regulating system in which oil is sprayed. In case of open gears the lubricants are applied by hand or by automatic drip or spray method. The choice of oil depends on tooth loading and pitch line speed. In general with increase in tooth loading, viscosity of oil should be increased. Low viscosity gear oils are used for high speed gears.
Refrigeration oils are manufactured from highly refined Naphthenic base stocks which provided better flock point characteristics as well as greater compatibility with most of the refrigerants. Lodha Manufactures a wide range of mineral oil type refrigeration compressor oils with viscosity starting from as low as 8 cst. These oils have got high thermal and oxidation stability to provide lubricity at both higher and lower temperatures.
Grease is a semi solid to a solid material of dispersion of thickening agent in liquid lubricant. The thickener can be either soap or non soap. The liquid lubricant is of mineral or synthetic type. Additives are added to impart special properties. Greases are used where it is not practical or convenient to use oil. It is used in machinery that runs intermittently or is idle for extended periods of time.
It is also recommended for components that are not accessible easily for lubrication and those subjected to extreme temperature, pressure or shock loads.
