What is the optimum utilization of a machine?
Optimum Utilization of Machine means to use a Machine in such a way that we produce at the maximum capacity after spending its minimum maintenance and other variable cost. In Short, Higher Productivity in low Cost.
Does low suction pressure have an effect on reciprocating compressors?
At very low suction pressure, the suction valves of reciprocating compressor will not work and there will be no gas in the cylinder during compression stroke, resulting some damage to the suction valves. If low suction pressure trip protection is not provided there can be some abnormal damage.
What is the difference between suction lift and suction head?
Suction lift is only negative. Suction head is positive or negative.Suction head is the distance between the surface of the liquid being pumped and the centerline of the pump. It can be positive or negative, and it can be affected by pressure or vacuum on the surface of the fluid. A negative suction head is also called suction lift.Example 1: A D/A under 15 psig is set 20 feet above the feed pump the effective suction head is 54 feet. (15 psig is equivalent to 34 feet of water).Example 2: A Condenser hotwell under 28 inches of vacuum (Hg) is set 16 feet above the suction of a propeller pump. The effective suction head (lift) is -15 feet.* (28"Hg = - 31 feet of water)Example 3: A sump pump is set 4 feet below the surface of the well. The effective suction head is 4 feet.*Note: Suction lift is only effective to a maximum of 21 feet, and 15 feet for hot water depending on temperature and pump slip.
What is vapour binding?
when pressure on the suction side of the pump drop below the vapour pressure of the liquid, vapour forms. It's caused because of insufficient suction head, high suction lift, excessive friction head, or high liquid temperature.
What are the factors govern the speed of reciprocating pump?
The factors that govern the factors of speed of reciprocating pump are:- 1. Cleanliness of Working Fluids 2. Temperature of Working Fluids 3. Piping Layout 4. Pump Foundation 5. Design of Suction and Discharge Pulsation Dampeners 6. Regular Maintenance
What is suction machine?
The opposite of a compressor. A vacumn cleaner is a suction device. Were you ever on a baby bottle. You used suction to get the formular out of there. A suction machine sucks!
What is the brief history of suction machine?
history of suction macine
What is the purpose of suction machine?
A suction machine such as an aspirator can be used to remove mucous and other unwanted fluids.
What is machine history cards for maintenance?
Machine Life.
Does MRI machines need maintenance?
A MRI machine may need maintenance. When the machine gets so old it can cause it to break.
What is maintenance in engineering?
It is one thing to engineer or build a machine, it is totally different thing to keep the machine running a its best. Maintenance is the work that keeps things running and finds future problems before the problem stop the machine running at all. Maintenance is also fixing problems that stop the machine so the machine can be restarted
What is the current for vacuum suction?
The current for vacuum suction can vary depending on the model and design of the vacuum cleaner. Typically, household vacuum cleaners use motors that draw between 5-12 amps of current. Commercial or industrial-grade vacuum cleaners may draw higher currents. It is important to check the specifications of the specific vacuum cleaner you are using to determine its current requirements.
Which weights require the least maintenance?
Machine weights require little or no maintenance at all.
What is the meaning of vacuum cleaner?
A machine for cleaning carpets, tapestry, upholstered work, etc., by suction.
Meaning of vacuum cleaner?
