How does centrifugal chiller work?
Vertical turbine pumps are centrifugal pumps mounted vertically. They operate on the same principals as all centrifugal pumps operate, with a rotating impeller around a central shaft. Vertical turbines can be found in single or multi-stage applications requiring high volume, high lift, as well as high discharge pressure.
Where are gear pumps generally used?
Generally gear pumps are used in hydraulic systems.
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
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.
Is it true that all hydraulic motor are positive displacement?
yes.only positive displacement pumps can be used in hydraulics
Can hydraulic pump can be used as hydraulic motor?
Instead of hydraulic pumps, hydraulic gear motor does not work. Hydraulic pump hydraulic motor blade is used instead.
What are the types of centrifugal pumps?
The four centrifugal pumps are the charging pump, sand pumps, shear pumps, and submersible slurry pumps. The machines are used for fluid transportation by rotational kinetic energy to hydrodynamic energy conversion.

Can a hydraulic motor be used as helm pump?
Instead of hydraulic pumps, hydraulic gear motor does not work. Hydraulic pump hydraulic motor blade is used instead.
What are the uses for a hydraulic pump?
Hydraulic drive systems like gear pumps, rotary vane pumps, screw pumps, bent axis pumps etc. One real life example of hydraulic pumps is the brake master cylinder in a car. You also see hydraulic pumps in excavators.
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.
When two centrifugal pumps are connected in series the discharge changes by factor of?
Centrifugal pumps in series are used to overcome larger system head loss than one pump can handle alone.for two identical pumps in series the head will be twice the head of a single pump at the same flow rate - as indicated in point 2.With a constant flowrate the combined head moves from 1 to 2.Note! In practice the combined head and flow rate moves along the system curve to point 3.point 3 is where the system operates with both pumps runningpoint 1 is where the system operates with one pump runningSeries operation of single stage pumps is seldom encountered - more often multistage centrifugal pumps are used.http://nuclearpowertraining.tpub.com/h1012v3/css/h1012v3_76.htm
What is use of centrifugal pump?
generally, centrifugal pumps are high discharge, low pressure generating pumps. to increase the pressure generated it is setup in stages wherein pressure increases from one stage to an other.mostly seen in daily life applications such as pumps for water tankers. even emergency fire fighter vehicles use these type of pumps. these are called dynamic or non-positive displacement pumps.
Name devices or machines that use fluid powerstate whether each is a hydraulic or pneumatic system?
cars-used to break gas pumps dishwashers rollercoasters
How are a hydraulic motor and hydraulic pump similar?
Hydraulic motors and hydraulic pumps are both components commonly used in hydraulic systems, and while they serve different functions, they share several similarities: Both are Hydraulic Components: Hydraulic motors and hydraulic pumps are both integral parts of hydraulic systems, which utilize pressurized fluid (usually oil) to transmit power. Both Convert Energy: While they convert energy in different ways, both hydraulic motors and pumps are involved in the conversion of mechanical energy to hydraulic energy or vice versa: Hydraulic pumps convert mechanical energy (often from an electric motor or an engine) into hydraulic energy by pressurizing fluid and creating flow. Hydraulic motors, on the other hand, convert hydraulic energy from pressurized fluid into mechanical energy, which can then be used to drive machinery or perform work. Both Operate via Fluid Flow: Both hydraulic motors and pumps operate by controlling the flow of hydraulic fluid. Hydraulic pumps create flow by drawing fluid into the pump and then pressurizing it, while hydraulic motors use the pressure of the fluid to generate rotational motion. Both Have Inlet and Outlet Ports: Hydraulic motors and pumps typically have inlet and outlet ports for fluid to enter and exit the component. In pumps, fluid enters through the inlet port and exits through the outlet port, while in motors, fluid enters through the inlet port to create motion and exits through the outlet port. Both Utilize Seals and Bearings: Both hydraulic motors and pumps often contain seals and bearings to prevent leakage and reduce friction, ensuring efficient operation and prolonging the lifespan of the components. Despite these similarities, it's important to note that hydraulic motors and pumps serve different purposes within a hydraulic system and operate in different ways to fulfill those purposes. While pumps are primarily responsible for generating flow and pressure, motors are designed to convert hydraulic energy into mechanical motion.
