Q:Which nuclear submarines use the shaftless pump technology?
The team led by academician Ma Weiming of China is now carrying out the research on this technology and has achieved initial success.. This technology is expected to be applied to the next generation of domestic submarines.
Q:What are the functions of a disposable infusion pump?
When the transfusion is too slow, the dosage may not be enough, or the infusion time is prolonged unnecessarily, the treatment is affected, and unnecessary burden is added to the patient and the nursing work. In routine clinical infusion, the infusion of hanging bottle is generally used, and the speed of infusion is controlled by the use of a manual clamp. The speed of infusion is not easy to be controlled accurately, and the workload is great.Treatment of cancer patients with chemotherapy and critically ill patients need to make drug infusion rates constant, by adjusting the input speed and duration of chemotherapy drugs is continuously injected into the uniform, not only to achieve the best effect of chemotherapy, and to minimize the side effects of chemotherapy drugs.People suffering from diabetes need to inject a certain amount of insulin at a certain speed. The previous approach is basically a large dose of insulin injection, which not only caused a huge waste, and the effect of time is relatively short, so for a conveying device of flow and velocity control, to carry a small amount of drugs and precisely control the conveying speed and flow.Some special drug delivery to the elderly, children and physical weak, such as drugs, antihypertensive drugs, sodium nitroprusside (three TPN codehydrogenase) when the infusion rate and dosage should seriously control accurately, otherwise it will have serious consequences.
Q:Does vacuum pump oil belong to dangerous goods?
Is the grease inside? How could it be dangerous goods? Absolutely not!
Q:What is the cause of the damage of pump bearings?
First of all, know your pump model, and what is the bad bearing, in order to accurately judge for you. Because in addition to some common reasons, the structure of different pumps, bearing damage caused by the reasons are different. Otherwise it is fraught with itching shoes.
Q:Why is the flow of the pump too small will occur cavitation phenomenon?
Why is it easy to produce cavitation when the inlet flow of pump is lowered?This is because the main performance parameters such as the head, power and efficiency of the centrifugal pump are not fixed, but vary with the flow rate. The curve drawn on a coordinate paper is called the performance curve or characteristic curve of the centrifugal pump. What happens when the flow rate decreases? The disadvantage of throttling adjustment is that the pump flow is small, and the impeller is easy to cause cavitation
Q:What's the word "pump"? Is that what advocates mean?RT
What is a "fan"?In recent years, the term "fan" often appears on the newspaper Web page, whether it is a team, a singer, a sports car and a toilet, all of which have their own fans
Q:What is the pump lift voltage? And how to suppress the pumping voltage rise?
[suppression of pumping voltage] the general use of the installation of absorption resistance to absorb the pump voltage rise. The simplest way to control the pump voltage is to connect the DC bus with an energy consumption resistor before releasing the pump voltage.
Q:How is the pump level of submersible sewage pump determined?
Pump water level must be higher than the water pump top, so that the motor running in the lower water temperature cooling environment, otherwise long-term operation will burn the machine
Q:What should be used to pay attention to the use of mechanical pumps?
When opening the pump, first close the outlet valve, lift the pressure, then open the outlet valve again, pay attention to the flow of the motor.
Q:Because the water pressure of the booster pump is not enough, it can not work automatically. It can only be operated by hand. It is inconvenient to use.
One possibility is the automatic type household booster pump used for a period of time, automatic failure phenomenon, it is mainly stainless steel and other metal products in pipes, long-term precipitation to shut off the power supply after unloading, unscrew the top screw, remove the plastic sheet to be cleaned, and then, according to the original reset, the normal debugging. Can be re used. But that's not why if your booster pump isn't working properly all the time.
