Hydraulic Winch Wireline Units

There are 2 hydraulic winch types of weriline unit: 1. Open loop 2. Close loop The Winch unit will be powered by the power-pack on separate skid. Hydraulic winch 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. Gearbox oil proceeds to the cooler, gearbox 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. Since from the beginning of time, man has been using machinery and tools to improve his quality of life and perfecting work efficiency. We are the only species on earth with the intelligence to design and implement tools that are able to assist us in our daily tasks. Over the past generations, technological advancements have improved the tools we use today, and have continuously revolutionized industries through each generation, in particular those of the past 150 years. The hydraulics industry in particular can be credited with significantly impacting and changing the face of human machinery forever. Hydraulic systems are tools and machines that rely heavily on high pressure liquid power to fulfill its functions. The state of purity of this liquid is crucial to be able to perform its purpose, which means the hydraulics liquid has to be run through an oil distillation system to filter out any impurities. Wide varieties of cylinders and motors will transfer this hydraulic liquid by means of control valves, hoses and tubes to the cylinders and motors. A lot of machinery used to perform important functions in our everyday use makes use of hydraulics in their function. Bulldozers, which are classified as crawlers, move making use of rigid plates joined to each other set on wheels, using continuous tracks. The purpose of this continual track movement is to allocate the mass of the machine over a much larger surface than mere wheels would be able to dispense. The bulldozer comes equipped with a 'dozer blade'. Even though a bulldozer is the term assigned to various types of machinery, the correct use of the term is only to describe a tractor with a dozer blade. This blade is utilized in moving debris, sand and soil, especially in construction work. In the first bulldozers, its blade was controlled by a brake, or winch system. They are now fitted with hydraulic cylinders, allowing much more exactitude in the blade's operation. Another piece of machinery which uses hydraulics in its function is a backhoe. It is a kind of excavating tool commonly referred to as a digger. In essence it is a tractor, fitted with an articulated arm with a digging bucket at the end, used in excavation scenarios. The arm which is closest to the vehicle is referred to as a boom, and the other part of the arm is the dipper. The bucket and the arm are powered by sophisticated and highly developed hydraulics that allow for accurate movement. Forklifts are powered by hydraulic systems as well. Such machines are powered by industrial trucks which are used in the lifting and transporting of heavy materials, especially moving and lifting pallets in warehouses and stock distribution centers. The mast of the forklift is what performs most of the work in raising and lowering the loads. It is obvious that hydraulics are used in our daily lives, even if we don't see it in our every day.
