Soft Foot

Soft foot is a common term used for machine frame distortion. The distortion is caused when one or more feet of a machine differ in height from the others. This, in turn, may be due to differences when the machine was manufactured, a squishy footage with oil film etc. between foot and base, a bent foot, or it may be induced by a pipe to which the machine is attached (e.g. a pipe on top of a pump), which prevents the machine from touching all its feet to its base. Types of Soft Foot Air Gap or Parallel Soft Foot: The most common explanation of soft foot is parallel or straight soft foot. When the hold-down bolt is loose, the foot simply does not reach the base, leaving a gap between the foot and the base. The bottom of the foot is parallel to the baseplate though. This condition is easiest to detect using either a feeler gauge or dial indicator. Downward Bent Foot: A common situation is known as a bent foot. Here the foot is touching the base on the outside portion, but t

Pump Shaft Alignment Procedure

Types of shaft alignment methods: Visual Line-Up Straightedge/Feeler Gauge Rim and Face Cross Dial Reverse Dial Laser Visual Line-Up The visual line-up method is the most common method of alignment. Used in initial installations, visual line-up allows technicians to analyze the working conditions and feasibility of installation. Straightedge/Feeler Gauge Straightedges are used to determine the offset between coupling halves. Corrections are made under all four of the machines feet. Feeler gauges or taper gauges measure the gap between coupling halves at the bottom and top of the coupling. Rim and Face This method is similar in principle to using a straightedge and feeler gauge, but more accurate since dial indicators are used. The rim reading measures the offset between the coupling halves. The face reading measures the angular difference between the faces of the coupling. Changes are calculated with the same formula as the straightedge/feeler gauge met

Alignment of Pumps & Shafts

One of the most important parts of pump setup is making sure that the pump and the drive motor are carefully aligned. Misalignment may account for over 50% of malfunctions in rotating machinery, leading to problems such as worn or broken couplers, vibration, and excessive wear of bearings, seals and wear rings. Excessive misalignment can even cause breakage of mounts or pump/motor casings. Once the pump set has been properly installed, the final alignment can be checked and, if necessary, corrected. Obviously, re-alignment is needed whenever the pump or motor are moved or replaced. What do we mean by ‘alignment’? Long-coupled pumps have a separate pump and motor shafts that are connected through a coupler. Ideally, these two shafts will be exactly parallel and have exactly the same centre-line. Flexible couplers can tolerate small alignment errors, but for smooth, trouble-free running, it is important to ensure that these two shafts are lined up to within the tolerances specified

Difference between Safety valve & Relief valve ?

Safety Valve Relief Valve Safety valves are used in gas or steam systems. Relief valves are used in fluid or compressed air systems . Opening will happen at the set pressure. Opening is proportional to increase in the vessel pressure. Opening of valve is sudden if the set pressure is reached. Opening of valve is gradual, if the pressure increases gradually.   Safety valve can be operated manually. Relief valve cannot be operated manually. Safety valve is set at 3% above the working pressure   Relief valve is set at 10% above working pressure.

How to take tappet clearance and adjust it ?

HOW TO TAKE TAPPET CLEARANCE? Make sure the engine is in cold condition. Make sure that the unit for which you are going to take clearance should be in TDC. But generally, there are more than 6 units in a marine four-stroke engine. So at the same, flywheel will show two unit at TDC. To make sure the particular unit is at the compression stroke and not at the power stroke. The one with the free push rod of both units is at compression stroke and the one with tight push rod is at power stroke. So avoid the one which is at power stroke. Use appropriate thickness filler gauge as mentioned in the makers manual. Gently try to push the filler gauge between the clearance of the valve and rocker arm. HOW TO ADJUST TAPPET CLEARANCE? Now you the clearance is more or less. Now comes the adjustment part. You need to open the nut on the rocker arm. After opening, you can adjust the clearance. Keep the filler gauge between the rocker arm and clearance of the valve at all time

What is tappet clearance, and why it is required ?

It is clearance between the valve stem and the rocker arm contact point. This clearance is required to accommodate the thermal expansion of the running gear between the camshaft to the valve and to ensure positive closing of the valve at all working condition and temperature. Often the requirement of tappet clearance is answered as, to maintain correct timing or change in clearance will lead to an early or delayed opening of the inlet or exhaust valves. Even though these are indirect effect of change in tappet clearance value and the one line answer should be to accommodate thermal expansion and ensure positive closing. Excessive clearance leads to 1. Valve opens late 2. Closes early leading to decrement in scavenging efficiency. 3. Mechanical constraints like damage, noise and impact on the working surface. Minimal clearance will lead to 1. Open early and closes late 2. Leaking of valve leading to burning of the valve seat and other constraints. 3. Compression pressur

Internal Combustion Engine Cycles

OTTO CYCLE An Otto cycle is an idealized thermodynamic cycle that describes the functioning of a typical spark ignition piston engine or a petrol engine. It is the thermodynamic cycle most commonly found in automobile engines using petrol or gasoline fuel. Process 0–1: Constant Pressure A mass of air (working fluid) is drawn into the cylinder, from 0 to 1, at atmospheric pressure (constant pressure) through the open intake valve, while the exhaust valve is closed during this process. The intake valve closes at point 1. Process 1-2: Isentropic compression In this process, the piston moves from bottom dead centre(BDC) to top dead centre (TDC) position. Air undergoes reversible adiabatic isentropic compression.We know that compression is a process in which volume decreases and pressure increases. Hence, in this process, volume of air decreases fromV1 to V2 and pressure increases from P1 to P2. Process 2-3: Constant Volume Heat Addition Process 2-3 is Isochoric (constant volu
