HYDRAULIC THEORY Introduction A hydraulic system is defined as a‚ ‘machinery unit which uses fluid as a pressure medium’. It has a number of advantages over an electrical system of a similar working capacity. Advantages: (1) The power to weight ratio is at least 14 times better than an equivalent electrical system. (2) Self-resetting overload protection. (3) Self-lubricating. (4) Infinitely variable speeds. (5) No static electricity. (6) Linear motion.

15C-1 The Lease Pumper’s Handbook Chapter 15 Enhancing Oil Recovery Section C SECONDARY RECOVERY C-1. Secondary Recovery. In simple terms‚ secondary recovery is the addition of basic water flood or gas flood (i.e.‚ pressure maintenance) as a continuous force. Secondary recovery methods should be introduced very early in the life of a field while the income and profits from the wells are high enough to pay for the additional equipment and installation costs. As noted in the following sections‚ there

The crew saw mud and gas pouring onto the floor of the rig. All the members of the crew instantly attempted to close the valve in the Blowout Preventer‚ which was intended to shut off the flow of high-pressure oil and gas from the well‚ but failed to seal the well because the drill pipe buckled for reasons that are still unknown. The crew could have redirected the flow of

Malard Manufacturing Company Malard Manufacturing Company produces control valves that regulate flows through natural gas pipelines. Mallard has approximately 1‚400 employees and has successfully produced a standard line of control valves that are price competitive in the industry. However‚ whenever the production of a new control valve is required‚ problems arise. Developments in electronics‚ metallurgy‚ and flow control theory require the introduction of new products every year or two. These

know there is no classic definition for dual evaporator system. The two evaporators may be connected in different ways with the capillary tube(s) and compressor. Aditional valves are required depending on the system assembly. The most used ones are the directional valve at the end of the condenser and /or a check valve at the end of the freezer compartment. In some systems there is no connection between the evaporators and the systems are independent‚ with two compressors. This system is also
