Most commonly used main pump in the fire service?
Centrifugal Pump
What is a centrifical pump?
A centrifugal pump is one that is used to transport the fluids throughout a vehicle. It uses this pump to get the fuel to the areas it needs to go.
What type of fuel oil pump is used with a rotary cup oil burner?
centrifugal
How do you change a bearing in a centrifugal pump?
A centrifugal pump is used on board most ships. There are many steps to overhaul one such as drain the pump, open the casing, remove the coupling, and replace the worn parts.
How do you differentiate between positive displacement pump and roto dynamic pump?
Gear pump is a positive displacement pump. (A positive displacement pump causes a fluid to move by trapping a fixed amount of it then forcing (displacing) that trapped volume into the discharge pipe. or A positive displacement pump has an expanding cavity on the suction side and a decreasing cavity on the discharge side. Liquid flows into the pump as the cavity on the suction side expands and the liquid flows out of the discharge as the cavity collapses. The volume is constant given each cycle of operation. A positive displacement pump can be further classified according to the mechanism used to move the fluid: a.Rotary-type, internal gear, screw, shuttle block, flexible vane or sliding vane, circumferential piston, helical twisted roots (e.g. the Wendelkolben pump) or liquid ring vacuum pumps. b.Reciprocating-type, for example, piston or diaphragm pumps. Gear pump is generally used for viscous fluid especially in hydraulic service. Gear pump are used for high head , low flow application. Widely used on car engine oil pumps. it is also used in various hydraulic power packs.. If you change the direction of gear pump ,suction will become discharge and discharge port become suction port. Gear pumps requires high degree of close clearances between gears and its housings. In centrifugal pump you will find above all in reverse . A centrifugal pump is a rotodynamic pump that uses a rotating impeller to increase the pressure and flow rate of a fluid. Centrifugal pumps are the most common type of pump used to move liquids through a piping system. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward or axially into a diffuser or volute chamber, from where it exits into the downstream piping system. Centrifugal pumps are typically used for large discharge through smaller heads. Centrifugal pumps are most often associated with the radial flow type. However, the term "centrifugal pump" can be used to describe all impeller type rotodynamic pumps including the radial, axial and mixed flow variations. Gear pump is high efficiency pump while centrifugal pump will have relatively low efficiency.
What type of pump used for water mist system?
it uses centrifugal pump type to maintain pressure of 120 kg/cm2
What pump will be used as main sea water pump?
It must be a centrifugal pump as the pump supplies water to coolers such as fuel oil ,lube oil and the fresh water generator. Also to reduce the scale formation in the pipes connected the flow rate is kept high. these demands can be fullfilled by a centrifugal pump only
What is difference betweenrotar of centrifugal pump and compressor?
pump is used to handle liquid and compressor is used to handle gases. other difference include blade shape etc..
What instrament is used to spin liquids to sparate components?
This is a centrifuge, based on separation of more dense matter based on centrifugal force.
What is the use of a pump?
Pump is a mechanical equipment used for transportation of liquids and slurries by mechanical means.
What are different types of vanes used in centrifugal pump?
there are three major types vanes are used for a centrifugal pumps those are 1.forward curved vanes 2.backward curved vanes 3.flat vanes
Which types of pumps are used in chemical industries?
Types of Pumps Used by Chemical Industries The Centrifugal Pump. By far the most common type of pump in this industrial sector, centrifugal pumps are based on a well-recognized operational principle. Helical Screw Pumps. Positive Displacement Devices. Diaphragm Pumps.
