The Utilization of Gearboxes in Diverse Industries

Filed under: Non classé — 1 August, 2011 @ 10:44 am

Gear boxes are equipments that are been used since ages in almost all types of industries and manufacturing units. Almost all types of machineries today need one type of gearbox to work. Used in a wide number of industries ranging from cement, paper and pulp, to power steel, petrochemical and sugar, gearboxes today come in with a lot of different features and properties. Below are the descriptions of some of the industries that make use of gearboxes:

Cement industry: The gearboxes are used in the cement industry to increase the amount of engine’s torque to generate a sufficient result. The gearboxes used in the cement industry are strong and higher in torque considering the size and power of the engines used. Apart from these, the cement industry also makes use of other variety of gearboxes like Bevel Helical, Bevel Epicyclical and Parallel Shaft, etc. These are used for various functions like augmenting the working of the engines, reducing their speed, incessant operation of the machines, compact installation, reliable load and sharp altering load, etc.

Paper and pulp industry: The paper and pulp industry is increasing its importance day by day. With the increase in the number machineries been used, the importance of gearboxes is also increasing gradually. There are a variety of gearboxes that are utilized in the paper and pulp industry. These gearboxes are made using materials like aluminum alloys, stainless and hardened steel, cast iron etc. some of the most common types of gearboxes used in the paper and pulp industry include Shaft Mounted, Helical and Spur Gearbox.

Steel industry: Steel industry is another industry that is raising its significance gradually. The machineries that are used in the steel industry to manufacture steel are hardwearing and this is the reason that they require gearboxes that are sturdy and enduring. The steel industry uses a variety of gearboxes like reduction gearboxes, pinion gearboxes, planetary gearboxes, etc. these gearboxes are used for the smooth running of the machineries.

Sugar industry: The sugar industry is one of the industries that require a lot of machineries to be used. Thus even the sugar industry makes use of an array of gearboxes of different gear ratios and torque capacities such as Planetary, Helical, etc. These gearboxes are either base or lip raised. These gearboxes enable the machines to function in a well-organized, even and soundless way.

Started in the beginning of 1978, Vashi electricals is handled by a team of experts and heading the gang is the young and dynamic Mr. Suraj Dodeja. Mr. Dodeja is well-known in the field of selling Industrial Electrical Products and is an authorized dealer for Bonfiglioli products like Bevel Helical Gearboxes, Bevel Epicyclical Gearboxes and Parallel Shaft Gearboxes, etc.

Hydraulic Wireline Units

Filed under: Non classé — 1 August, 2011 @ 10:40 am

There are 2 hydraulic types of weriline unit:

1. Open loop
2. Close loop

The Winch unit will be powered by the power-pack on separate skid. Hydraulic power is supplied by connecting the power-pack to the wireline unit using hydraulic hose and quick coupling union.

Hydraulic oil passed from the reservoir tank through a suction strainer mounted inside the tank, to the hydraulic pump which driven by the diesel engine. On leaving the pump under pressure, the oil passes through a tee connection which exposes the pressure to the pressure control relief valve. The valve is set to open at 2,400 psig.

The minimum pressure signal for this valve can be overridden by the pilot relief valve to adjust the maximum system pressure to any valve less than 2,400 psig. The operating pressure of the system can be read on the pressure gauge. From the pressure relief valve the oil proceeds to the 4-way valve directional controls the directional control valve and then to the motor. The 4-way valve controls direction of rotation of the drum. When the handle is pulled toward the operator, the drum rotates toward him, when the handle is pushed away from the operator, the drum rotates away from him. When the valve is in the neutral position, oil flow directly to return line.

Hydraulic oil proceeds to the cooler, hydraulic filters and back to the reservoir tank.

Types of wire used in workover and completion operation are « Slick line », « Braided line », and « Conductor line ». « Slickline », that is, single strand wire of 0.066″ up to 0.125″ diameter is carried on a single drum winch unit or double drum winch unit.
