A chain pump is a type of water pump that uses a chain to move water from one place to another. It works on the principle of a continuous loop of chain moving through a series of sprockets, with attached buckets that lift water as the chain passes over the top sprocket and discharge it as the chain reaches the bottom.
The basic function of a pump is to do work on a liquid. It can be used to transport and compress a liquid. In industries heavy-duty pumps are used to move water, chemicals, slurry, food, oil and so on. Depending on their action, pumps are classified into two types — Centrifugal Pumps and Positive Displacement Pumps. While centrifugal pumps ...
The diaphragm or bladder may itself exert a pressure on the water, but it is usually small and will be neglected in the following discussion. Case 1 is an empty tank at the charging pressure P c (gauge). The total volume of the tank is V t. Case 2 is a tank in use, with the air pressure at pressure P (gauge) and a water volume of V
A water dredge or water eductor may be used for the same purpose. [1] Typically, the airlift is constructed from a 3-metre to 10 metre long, 10 cm diameter pipe. A controllable compressed air supply vents into the inside, lower end of the pipe (The input end always being the lower end).
Durability needs to be incorporated into pump design to the handle the heavy use (and abuse). The India Mark II is a human-powered pump designed to lift water from a depth of 50–80 m. [1] The Mark II is world's most widely used water handpump. [2] The pump was designed in the 1970s to serve village water needs in developing countries and ...
Hand pump, manually operated; Injector, a jet-driven pump; Mechanical or rotary lobe pump requiring mechanical parts to pump water; Solar-powered water pump; Pump driven by air as used by the Amish; Pump driven by air as used in the Australian outback; Manual pumpless or hand pump wells requiring a human operator; The pump replaces the use of a ...
The PlayPump water system is a playground merry-go-round attached to a water pump. The spinning motion pumps underground water into a 2,500-liter tank raised seven meters above ground. The water in the tank is easily dispensed by a tap valve. According to the manufacturer the pump can raise up to 1400 liters of water per hour from a depth of 40 ...
The strength of the vacuum produced depends on the velocity and shape of the fluid jet and the shape of the constriction and mixing sections, but if a liquid is used as the working fluid, the strength of the vacuum produced is limited by the vapor pressure of the liquid (for water, 3.2 kPa or 0.46 psi or 32 mbar at 25 °C or 77 °F). If a gas ...
