Q:25KW what is the lift of the pump?
Never mind lift and power of pump, series and pump impeller diameter and impeller, the same power pumps may lift hundreds of meters, but the flow may be only a few parties may also lift only a few meters, but the flow may be hundreds of square. The general rule is that under the same power, the flow of the head is high, the flow of the head is low, and there is no standard formula to determine the lift, which is determined by the conditions of your use and the model of the pump.
Q:Can centrifugal pumps be idle? What's the status of the empty transfers?
It burns and seals when idling. The individual thinks that it can be indirectly reacted according to the pressure change in the pipeline, and the electric contact pressure gauge can be installed on the suction pipe
Q:A pump, the flow rate of 30T/H per hour, lift 30 meters, should be allocated more power motor?
Depends on how big your water pump is. How long is the pipe length?
Q:Water pump 50HZ impeller and 60HZ what is different, why not the same?
50HZ motors are usually not damaged if they run on a 60HZ circuit, but the speed will increaseConversely, the 60HZ device runs on the 50HZ circuit, and the speed drops.Because of their different frequency, make them synchronous speed rotating magnetic field winding is different, so the rotor induction (induction motor) speed will be different, the pump will naturally lift Gao Shaoxu, and often will not cause damage to the equipment, because many things are in the 50HZ 60HZ.Second, for synchronous motors, the increase and decrease of speed is much more obvious than that of induction motors, because their rotor and motor are synchronous and keep synchronous speed
Q:In the design specifications, for example, the water pump requirement is two. What does that mean? Can 3 pumps be opened at once?
Use 2 units and reserve 1 units. You can open 2 at the same time. Can three drive at the same time, depending on your water pipe layout, whether there are three sets of pipes, yes, three units open at the same time.
Q:What is the function of open circulating water pump and shutdown in thermal power plant?
According to the water quality difference, the purpose is to provide the corresponding cooling water, for the system oil cooler, machine seal and other cooling. Open water directly from the circulating water pipe to use, the pump is delivered to the host, the small machine oil cooler, water quality is not very high, the circulating water drainage to the back pipe, water through the water filter filter impurities. The closed water takes the self closing water tank, which is used for removing salt water. General supply pumps, water pumps, sealing cooling water, condensate pumps, sealing water, generator, hydrogen cooler and other requirements of good water quality system, closed water self circulation, and through the cooler and open water circulating water heat exchange.Thermal power plant is referred to as the thermal power plant, is the use of coal, oil and natural gas as a fuel production power plant, it is the basic production process: fuel combustion in the boiler heating water into steam, fuel chemical energy into heat energy, steam pressure and steam turbine rotation, converts heat energy into mechanical energy and steam turbine rotate the generator, the mechanical energy into electrical energy.
Q:When did the pump start?
The promotion of water is very important to human life and production. There are various ancient water appliances, such as Egypt's chain pump (seventeenth Century BC), China shadoof (seventeenth Century BC), Burton (Eleventh Century BC) and water (first Century ad). The famous spiral rods invented by Archimedes in the third Century BC can lift water to a few meters in a steady and continuous way, and the principle is still used by modern screw pumps.In 200 BC, the ancient Greek fire pump craftsmen invented by Kurt Siby Lucius is a kind of piston pump has the most original, the main components of a typical piston pump piston pump, but only after the steam engine was developed rapidly.1840~1850 years, the United States invented Worthington pump cylinder and steam cylinder opposite, the direct impact of the piston pump, marking the formation of modern piston pumps. Nineteenth Century was the climax of the development of piston pumps, which were already used in a variety of machines, such as water presses. However, with the rapid increase in water demand, from 1920s, the piston pumps with low speed and large flow were gradually replaced by high-speed centrifugal pumps and rotary pumps. But in the field of high pressure and small flow, reciprocating pump still occupies the main position, especially diaphragm pump and plunger pump have their own advantages and are used more and more.
Q:The pump assembly and the pump are not a thing
The pump assembly and the pump are the same, just name different, as all the car parts are called assembly, the pump is the same, called water pump assembly. Also, the pump half assembly is the water pump head.A pump is a machine that transports liquids or pumps liquids. It will be the prime mover of the mechanical energy or other external energy transfer to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids. Pump performance of technical parameters are flow, suction, lift, shaft power, water power, efficiency, etc.; according to the different principles of work can be divided into volume pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.
Q:What is the reason that the centrifugal pump outlet pressure decreases and the operating current increases?
Export pressure reduction generally 2 reasons: 1, blade wear, 2. mechanical seal leakageThe increase of electric current should be caused by severe wear of the friction pairs of mechanical seals, resulting in increased resistanceIt is suggested that mechanical seals and blades be changed.
Q:The diving pump in the aquarium stops and stops on the goldfish
The submersible pump has been on all the time.
