In case of emergency, if the cylinder stops, the motor does not. So it can be harmful for motor. Designers couple the high power motor to the cylinder of pump by means of a clutch. so the motor can continue to rotate while the cylinder stops.
Also in case of closing the outlet valve of a pump, the pressure in the cylinder can fail the cylinder or crankshaft and accessories. in this case the clutch can separate the power from motor to the pump and prevent failure of pump.

Advantages of double acting reciprocating pump?
Reciprocating pumps will deliver fluid at high pressure (High Delivery Head).They are 'Self-priming' - No need to fill the cylinders before starting.
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 is the difference between screw chiller and reciprocating chillers?
screw is low maintenance than reciprocating reciprocating is more saving for power supply the compressors in screw is semehermatic but in reciprocating is open
What are the Aircraft instruments in a reciprocating engine?
aircraft engines are normally reciprocating engine or pistan engine, the Aircraft instruments in a reciprocating engine arecylinderpistonand so...................
Could you show me Diagrams of different types of hydraulic pumps?
I can't create or display diagrams directly, but I can describe different types of hydraulic pumps. Common types include gear pumps, which use meshing gears to move fluid; vane pumps, which use sliding vanes to create pressure; and piston pumps, which use reciprocating pistons to generate high pressure. Each type has its unique design and operating principle suited for various applications in hydraulic systems. For diagrams, you might consider checking engineering textbooks or reliable online resources.
Are the triplex mud pumps centrifugal?
No, they are reciprocating.
Where do you use reciprocating pumps in daily life or in industrial applications?
Daily life you use reciprocating pumps buy using your water faucet, pumping gas or simply using a suringe for medicine.
What is closed coupling pumps?
In centrifugal pumps there are two major types of pumps,One is Bare shat pumps and another one is close coupled pumps.Bare shaft pumps having casing,bearing housing with shaft which has to be coupled by means coupling arrangements like love joy,Tyre and spacer type coupling with electric motor.But in the close coupled pumps the motor will looks like a inbuilt arrangement to avoid extra shaft length and shaft deflection.

Are Mechanical seals installed on all reciprocating pumps?
No, mechanical seals are not installed on all reciprocating pumps. While many reciprocating pumps use mechanical seals for their efficiency in preventing leaks, some may utilize packing seals or other sealing methods depending on the application, fluid being pumped, and design preferences. The choice of sealing method often considers factors such as pressure, temperature, and maintenance requirements.
Why foot valve is not required in reciprocating pumps?
A foot valve is not required in reciprocating pumps because these pumps can create suction and effectively draw fluid into the pump chamber during their intake stroke. Unlike centrifugal pumps, which rely on continuous flow and need a foot valve to maintain prime, reciprocating pumps can handle intermittent flow and are designed to operate with a positive pressure during the suction phase. Additionally, the check valves within the pump ensure that fluid flows in the desired direction and prevents backflow, eliminating the need for an external foot valve.
Is receiprocating pump advantageous or centrifugal pupm?
A reciprocating pump is an advantageous pump. Centrifugal pumps convert energy into rotation to power themselves. A reciprocating pump uses a back and forth linear motion.
Why priming is not require in reciprocating pump?
Priming is not required in a reciprocating pump because these pumps are designed to create suction on their own. Unlike centrifugal pumps, which rely on a fluid-filled casing to initiate flow, reciprocating pumps utilize a piston or diaphragm mechanism that draws fluid into the chamber during the suction stroke. This action effectively removes air and allows the pump to operate efficiently without prior filling. As a result, once the pump is started, it can effectively handle both liquids and gases without the need for priming.
What is to and fro in motor?
"To and fro" in a motor typically refers to the reciprocating motion of a component, moving back and forth along a path. This motion is often seen in devices like linear motors or actuators, where the motor converts electrical energy into mechanical energy to produce linear movement. It is essential in applications such as conveyor systems, pumps, and various machinery where repetitive motion is required.
Can 3 phase induction motor start and run rated speed by 2 phase?
yes, It would run as long as the motor was not coupled to a load. Coupled to a load the motor would have no torque and would stall.
Which pump is more efficient Centrifugal pump or reciprocating pump?
positive displacement pumps will always be more efficient than centrifugal pumps due to a centrifugals inherent internal fluid slip recirculation and losses.
