- Q: Know flow and lift how to calculate the pump power?
- The pump power (kw) ={9.61* flow (cubic meters per second) * head (m)}/.Where ETA is device efficiency, including mechanical, electrical loss and other factors, generally between 55%~80%. The smaller the pump, the lower the efficiency.
- Q: What is the dry running protector of screw pump? What's the principle and function? Thank you
- When the temperature reaches a certain value, the signal is transmitted to the electric control box through a dry running protector, and the electric control box is used to stop the screw pump so as to protect the screw pump.
- 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: I live on the 8 floor. Often there is no water. Life is very inconvenient. What kind of pump do I have to install? What should I pay attention to when I buy it? What's the pump for that brand? Should it be installed in that position?
- (8) check the suitability of the foundation and whether the size of the foundation corresponds to the size of the pump.(9) find the position of positive pump and motor, pump set and anchor bolt and the inlet and outlet flanges, to ensure that the flange torque of the pump conforms to the standard. Check the inlet and outlet piping before alignment. Make sure the weight of the inlet and outlet pipe does not exert force or torque on the pump. When looking for, should also pay attention to eliminate the pump rotor movement, so as to avoid the end gap error. If checked after the pump is working, it should be carried out under cold condition. It is important to draw attention to the fact that the pump set of the complete set of factory is only rough looking (checked with a ruler) when it is shipped. It may cause displacement when it is transported.
- Q: How is the pump level of submersible sewage pump determined?
- Below the top elevation of the sump, 200 is the warning water levelBut note: 1, the effective volume of the sump meets the requirements. 2, the pump should have enough submerged water level
- Q: What is the working pressure of the hydraulic pump in the hydraulic transmission system?
- The operating pressure of the hydraulic system depends mainly on the load. Generally speaking, the working pressure of the hydraulic system means the highest working pressure of the system. If the pressure is higher than the value of the equipment, the relief valve works to relieve pressure. The actual working pressure of the hydraulic system is determined by the load, which refers to the actual pressure of the hydraulic oil and can be read directly from the pressure gauge. The pressure increases with the increase of the load. You Li's balance can know: the thrust of the cylinder = the load, the thrust of the cylinder = the working pressure of the hydraulic oil, the working area of the cylinder, the working pressure = the load / the area of the cylinder.
- Q: How many pumps does the 80cm tank use?
- Filter pump to select the water per hour can be filtered more than 3 times, I personally feel that this is almost enough. Of course, the more times the better, but also consider that if the pump is too large, the water inside the tank will be too large.128X3=384LThat is, the flow must be more than 384L/H of the water pump.You can buy a bigger pump, because the pump for a long time there will be some attenuation and domestic things in general to sign data, so it should be based on your actual situation to buy. Taobao on this category is about 20~40 yuan.
- 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?
- Centrifugal pumps are too big to measure.There is a reason why the centrifugal pump does not measure up:The pump inlet pipe blockage, leakage.The pump inlet pressure is too low.
- Q: What is the series of pumps? What is the difference between a unipolar and a multilevel? What is the meaning of each "first class"?
- Each impeller is of the first stage. (two impellers share only one level, and exit is only level one)
- Q: No negative pressure water supply equipment, both the main pump and auxiliary pump, power is not the same, how to choose the control cabinet?
- Non negative pressure variable frequency water supply means no negative pressure superposed water supply equipment. When running, it is connected directly to the water supply pipe. Always test the pressure of tap water pipe network and water supply pipe network pressure control system, when the water pressure is lower than the pressure required by the user, the frequency conversion device based on water automatically control the pump speed through the steady flow compensator of water balance, maintain a constant pressure water supply. In the multi pump system, the control system can automatically dispatch the water pump according to the water consumption. It can balance the working time of the pump and ensure the pressure of the water supply. When the water supply pressure satisfy the required pressure, the system automatically stops the pump by the external water supply pipe network directly.
