◊ Application

RS Series vacuum pump is compact, light and attractive in design. It uses the big starting torque and is specially designed for low temperature environment. It is guaranteed start normally in winter’s low temperature. It is applicable to vacuum packaging, vacuum freez

This kind of pump is widely used in food packaging, scientific research, medical treatment, electronics, chemicals, medicine and laboratory of universities and colleges.

ing, automobile reparation, gas analysis, medicine mechanism, printing mechanism and other vacuum evacuations.

◊ Technical data

Q: Piston filling and peristaltic pump filling which precision is high?: First of all, we should know the working principle of each, and analyze the accuracy from the principle, this problem is very important. Piston filling, such as the injection of drugs that we have been ill, the accuracy of the piston pump depends on the accuracy of the motor and the area of the unit cross section

Q: A residential building with a floor height of 11 stories and a roof height of 33 meters. The height of the water tank is 37.7 meters. The basement is -3.3 meters, only set fire hydrant, fire pump only consider the indoor fire water, fire flow should be 10l/s. Now select a fire pump, concrete should be much traffic, big head, flow determine how? How to determine the head, I hope to say some more detailed, thank you, and there is to explain this question, why is the fire pump lift 120?. Thank you: Modify the part: (the design of regional common fire pump should be in accordance with the requirements of the original design, building design) contains a 55m high building, and the basement is about 6m, the pump reached in the basement height about 61m (common fire pump should be based on the highest floor of other low floor area, low ring and take in this case, relief measures) 61 levels, the most unfavorable hydrant to reach 0.07MPa (maximum allowable 0.5MPa) plus loss of lift at least about 90m more appropriate, of course can be higher to take relief measures (120 too high), the basic flow of lossless (with the same time there is only one building fire) according to the maximum amount of a building fire water pump set can be, there must be a backup with a preparation, and then select the appropriate pump manufacturer specification query.(the 20 houses on 99m are only shared with a 135m pump)

Q: The difference between diaphragm pumps, vacuum pumps and centrifugal pumps: The diaphragm works by changing the size of the diaphragm. When the cup is covered with an eraser and the edge is airtight, then pressing the rubber or pulling the rubber outward will make the pressure in the cup increase or decrease. Use this principle, in the pressure of an hour from a hole suction medium, when the pressure is large, from another hole extrusion medium, so as to achieve the purpose of conveying.

Q: If you use an ordinary 15W submersible pump, put it in the tank, if the leakage, the fish will hang it?: What will happen then? The aquarium glass is an insulator. The water in the fish tank has the same potential as the live wire, and the fish is like a bird standing on the fire line. No electricity flows through their bodies, so they won't get electrocuted. But if you put your hands into the water, you will get an electric shock, because the line voltage through the water, then your body and the earth to form a loop, current flowing through your body you will get (of course, if you stand on the insulator does not get an electric shock)

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

Q: How is the pump level of submersible sewage pump determined?: Generally as:The bottom elevation of sump sump plus 300 is the water level of pump stopThe top 300 of the sump top elevation is the pump water level

Q: Working principle and structure of external gear pump: The principle of the gear pump, gear pump structure consists of two gear mesh together with each other, and composed of pumps known as gear pumps. It relies on the gear teeth meshing space change in volume to transport the liquid, it belongs to the rotary pump, also can be considered as a volume pump. There are many kinds of gear pumps. According to the meshing mode, it can be divided into external gear pump and internal gear pump. According to the tooth shape of gear, it can be divided into positive gear pump, helical gear pump and herringbone gear pump.

Q: If the calculation of the required pump flow is 45, lift 110, and the actual pump flow 100, head 125, what will happen in operation? Can I use it properly?: First of all, the performance curve of the centrifugal pump is similar to the track of the train, and the train can not run away from the track.Secondly, the performance curves of centrifugal pump mainly include flow head curve, efficiency flow curve, power flow curve. When the pump is ready, the curve is fixed. In practical application, after determining the flow rate, the corresponding lift head, efficiency and power (relative to density) are determined. General requirements for centrifugal pump operating in the vicinity at the highest point of efficiency, the efficiency of the flow curve is similar to parabola, so if the actual operation condition deviated from the rated point, whether large or small, will cause the decline in pump efficiency (generally rated value is less than 15%), increased operating costs.

Q: Suction stroke and lift of water pump: Lift pump lift pump can lift refers to the height, usually expressed in H, the unit is m. centrifugal pump lift to the impeller center line, divided by two parts. The vertical height from the pump impeller centerline to the water surface, the water pump to suck water up to the height, called water head, referred to as suction pump impeller; from the center line to the vertical height of the water tank, the water pump can put pressure on the height, called water pressure head, referred to as the pressure. The pump head = + suction head pressure water head should be pointed out that the nameplate marked head refers to the pump itself can produce lift, it is not with the pipe flow friction resistance caused by the loss of lift. In the selection of water pump, attention can not be ignored. Otherwise, will be pumping Sheung Shui.

Q: Which nuclear submarines use the shaftless pump technology?: At present, the submarine has been used in the pump jet technology, the most representative is the United States Virginia class submarine and the Russian North Sea God class submarines.. And shaftless pump is a derivative application of superconducting technology, which is more advanced than pump jet technology..If you want to learn more about shaftless pump technology, you can find relevant papers online.
