Answer Posted / sunil kumar singh
A centrifugal pump is one of the simplest pieces of
equipment in any process plant. Its purpose is to convert
energy of a prime mover (a electric motor or turbine) first
into velocity or kinetic energy and then into pressure
energy of a fluid that is being pumped. The energy changes
occur by virtue of two main parts of the pump, the impeller
and the volute or diffuser. The impeller is the rotating
part that converts driver energy into the kinetic energy.
The volute or diffuser is the stationary part that converts
the kinetic energy into pressure energy.
Note: All of the forms of energy involved in a liquid flow
system are expressed in terms of feet of liquid i.e. head.

Hai, iam renjith. my qtn about the calorex heat and cool pump. What is the reason of the above machine is trip on high pressure. r134a gas using in this system. 8 months old. model is calorex propac 90(3 phase). This system has 2 compressor. Both are starting on 13amps after that rise up to around 21 within 1 minute. After will be trip on high pressure. Showing 68 psi in suction side on standby mode. Can i have a solution without delay?
