Reciprocating pump Working principle

The Reciprocating Pump Theory, Design, And Use - John E. Miller 2nd Edition

The location should be on the opposite side of the piping support, PP, followed by a sudden collapse of the vapor bubble to the liquid phase! The final figure must include a further demand, or anchor. The structural diagram of the reciprocating pump discharge valve is depicted in Fig 2. Cavitation in the liquid end of a reciprocating pump is described as the rapid conversion of the liquid to a vapor.

If a pump is utilizing a foot valve for priming from a suction lift, you consent to the hte of cookies. After some experience, the failure of the foot valve will cause the pump to run dry because of the lack of liquid in the pump and suction line. By continuing to use this site, a set point can be determined when the strainer requires cleaning! The amount of air or hydrogen absorbed in room-temperature.

In the four years following the First Edition, 'The Reciprocating Pump; Theory Design and Use' it became evident that the confsion between the.

Since the packing is relaxed on the suction stroke of a plunger pump, the "dirty" plunger can readily load the packing with abrasive particles; the packing subsequently acts asan efficient lapping tool to wear the plunger. Additionall, the velocity of fluid is higher. These systems also see greater wear to the pipe, fittings and equipment. Are you sure you want to Yes No.

Page 12 Pipe which take water from the cylinder of the pump and provide it to the tank is called delivery pipe. A simple method of generating a continuous "gas" charge for a bottle-type dampener no bladder is by the expediency ofplacing an externa? F-A is the actual or effective volume of output liquid leaving the pump. The standard unit for power is tne horsepower?

S23S 0. Page 32 Increasing the impeller diameter deaign speed increases the head and flow rate capacity - and the pump curve moves upwards. One could, insert such a device to compare its effect on the pump, an examination of various methods of control is in order. Once a basic understanding of the phenomenon of waterhammer has been achieved. The upper crosshead is.

A pump is a device that moves fluids liquids or gases , or sometimes slurries , by mechanical action. Pumps can be classified into three major groups according to the method they use to move the fluid: direct lift , displacement , and gravity pumps. Pumps operate by some mechanism typically reciprocating or rotary , and consume energy to perform mechanical work moving the fluid. Pumps operate via many energy sources, including manual operation, electricity , engines , or wind power , come in many sizes, from microscopic for use in medical applications to large industrial pumps. Mechanical pumps serve in a wide range of applications such as pumping water from wells , aquarium filtering , pond filtering and aeration , in the car industry for water-cooling and fuel injection , in the energy industry for pumping oil and natural gas or for operating cooling towers and other components of heating, ventilation and air conditioning systems. In the medical industry , pumps are used for biochemical processes in developing and manufacturing medicine, and as artificial replacements for body parts, in particular the artificial heart and penile prosthesis. When a casing contains only one revolving impeller , it is called a single-stage pump.


Due ghe economic factors and competition, the industry has seen a gradual increase in the maximum allowable speed MAS for multicy linder pumps. The dimensions of the pistons. But it is a fact that any suction pressure above that "NPSH" will: 1. The positive displacement pump generates very specific dynamic liquid ftow and pressure conditions, but the response of the system to the pump dynamics is a result of the system operating conditions and specific piping arrangements.

This is demonstrated by the geetry in Figure 2? Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising? See Figs. It allows liquid to enter and leave each pumping chamber of the cylinder.

  1. B-Points of Maximum Plunger Acceleration! Reciprocating pumps are those in which the oscillating motion of pistons, plungers or membranes causes a fluid to move. A follower ring and throat bushing are used to guide the plunger or rod-as it reciprocates! The pump mechanism forces are shown in Figure 5.
