Design
Single- or multistage centrifugal pumps in ring-section design, single                                                       entry; for vertical and, depending on the number of stages, angled and                                                          horizontal installation; mixed flow hydraulic systems available with                                                            reduced impeller diameters; driven by submersible motors. Suction casing                                                        fitted between pump and motor, equipped with strainer to protect the                                                            pump from coarse particles in the fluid. Permissible sand content in the                                                        fluid: 50 g/m³. Pumps with non-return valve or connection branch on option.

Q:Piston filling and peristaltic pump filling which precision is high?
If the unit area is large, the accuracy of the plunger is certainly not high. The peristaltic pump is used by means of extrusion roller extrusion pump to promote the solution, this also depends on the unit cross section size, the same motor accuracy is very important.
Q:Suction stroke and lift of water pump
The absorption process is also called the "largest self-priming height" (also can be understood as "the degree of self suction). Micro pumps do not add water at the circumstances, can automatically water suction pump up the maximum height (the vertical distance from the pump to be pumped from the mouth of pumping liquid).Generally lower than the water pump positioned equal when there is self-priming pump required capacity. For example, outdoor tourism, need to extract the water in the river, with the best micro pump self-priming ability (impossible to people ran to the river water inlet pipe with water. It) or pumping the liquid corrosion, easy to add water and so on occasions.
Q:What is the difference between an air pump and a water pump?
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:Fire pump control cabinet There are 6 pumps, two indoor fire hydrant pumps, two spray pumps, and two outdoor pumps
Indoor fire hydrant pump in addition to remote direct Kai, there are modules to start function, that is, on the cabinet to add control module, bus linkage pump, but also fire hydrant button, direct pumping function, a total of three functions.Outdoor fire hydrant pump in addition to remote direct Kai, but also an electric contact pressure meter detection system, water pressure from the pump and high pressure pump stop function.
Q:How much water does the water ring vacuum pump run for an hour? If there is no steam separator, does the water vaporize?
For example: water storage is relatively small, it needs to reduce the temperature of the heat exchanger. If the tank is relatively large, it does not need cooling water circulation pump again when the temperature is very low, there is no need to heat exchanger. So you need to ask how much water this is not OK.In a soda separator problem:
Q:What does centrifugal pump mean horizontally?
In other words, pump casing and pump body along the horizontal center of the pump leaves into the upper and lower halves, so that when the pump leaves the pump cover open, you can pump and bearings as a whole pumping out. No need to remove the pipe. I don't know. Do you understand?.
Q:What is the series of pumps? What's the difference between a unipolar and a multistage?
A single-stage pump is a pump with only one impeller. 2, a multistage pump is a pump with two or more impellers. The multistage pump can increase the pressure and lift the head higher. Level 1 means a booster impeller.
Q:What are the characteristics of a vertical multistage centrifugal pump?
A liquid that is primarily diluted, clean, non corrosive, explosive, or similar to water but contains no solid particles or fibers. Because of its high flow and large lift, it is widely used in fire fighting, water supply and air conditioning unit cooling water transportation in high-rise buildings.
Q:What's the difference between non negative pressure and variable frequency water pump?
Re pressure to a given pressure pressure zone water supply, than frequency conversion water pump energy savingFrom a health perspective, a water tank variable frequency water pump, water tank and the atmosphere, easy occurrence of water pollution two, no negative pressure equipment without negative pressure tank and pump and valve fittings etc., no water tank, the whole process of water supply of water is completed in a closed system, with air contact to avoid two pollution problems water supply.From the management point of view, no negative pressure is fully automatic intelligent operation, reduce management costs, no water tank, reducing the trouble of tank cleaning. No negative pressure is the upgrading of variable frequency water pump products
