Q:What is the water pump population pre rotation, what harm?
The turbulence formation flow entrance, the flow direction is complex, impact, vibration, easy to damage the device before; if there is no water pump entrance pre swirl design will affect the safety and service life of equipment.
Q:Pump suction and pressure side road why should vacuum table and pressure gauge, and what role they have?
The water pressure (vacuum) is measured by the vacuum meter. The pressure gauge is used to measure the pressure at the water end, and the difference between the two is the lift of the pump
Q:What is the function of a submersible pump?
Submersible pump motor and pump is directly connected with the water pump body into the water to work, it is suitable for the extraction of groundwater from wells, can also be used in rivers, reservoirs, canals and other water projects: mainly used for irrigation and plateau in the drinking water, but also for the city, factories, railways, mining and construction site the use of water supply and drainage.Characteristics of submersible pumps for well1 、 motor, water pump, submerged operation, safe and reliable.2, the well pipe and pump water pipe without special requirements (i.e.: steel tube wells, tube wells, Doi ash can be used).3, installation, use and maintenance of convenient, simple, small footprint, do not need to build pumping stations.The structure is simple, and the raw materials are saved.4, submersible pump conditions are appropriate, properly managed, and has a direct relationship with the service life.
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:Why should the water pump be opened in time after the pump is started?
Just like peeing, just getting ready to pee, it feels like holding a chicken.
Q:What is the function of the backflow pipe of the fire pump?
Generally, it is used to test the fire pump. The procedure is to start the fire pump - turn on the return pipe - return the water to the pool. The purpose of the installation is to prevent damage to the pipe caused by the excessive pressure caused by the pump.
Q:Does the lift of pump relate to the water level of import and export?
Pump head refers to the inlet and outlet pressure head, that is to say, the entrance resistance greatly affects the pump lift, of course, this inlet resistance has a degree, too large water pump does not bring water or cause water pump cavitation. If the water level at the pump inlet is the same height, the inlet flow resistance of the pump may not be considered.
Q:Water pump is not Sheung reason
You should look at the suction port of the pump, there is no check valve, if there is water will not flow back to the pump bodyIf the pump is not water and not bad, the main reason is that the pump does not flush water, or suction pipe into the air
Q:Fully automatic self-priming pump
Yes, add a water level controller.Try electronic water level switch with stable and reliable performance. In Baidu search "electronic water level switch official website", you can find more information, model is BZ201
Q:30kW what is the flow rate of the pump?
Estimated traffic: Q = nP/ (9.8H), =70%*30/ (9.8H), =2.14/H (m^3/s)It is estimated that the efficiency of the water pump unit n=70%, power P to kW as a unit, the head H to m as a unit, you go to check the head H is how many meters, into the formula can be considered the flow rate is how many cubic meters per second.
