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: What should I pay attention to when buying a pump?: There are hundreds of water pump manufacturers in China, some of the family owned private enterprises are assembled in some areas, and the quality of the products is very good and bad, which makes it difficult to choose and buy. The main points are as follows:First, according to the required flow, lift, shaft power, efficiency, the necessary cavitation margin (or suction) and the use of conditions, the initial determination of the pump type, name, select the rated value and the required parameters of the same pump.

Q: Brief description of centrifugal pump on / off operation: (3) check whether the turning rotor is easy and flexible, check the pump body is clang or friction sound.(4) the protective cover is installed, and the shield contact.(5) clean the pump frame and do a good job of sanitation.(6) open the inlet valve, make the liquid full of pump body, open the vent valve, clean the air and close it. If the hot oil pump, it is not allowed to open the air valve exhaust, to prevent hot oil channeling spontaneous combustion, if there is a dedicated vent pipes and tanks, you can vent the pipe line air and cold oil.(7) the hot oil pump should be preheated slowly before starting. Especially in winter, the pump body and the pipe should be preheated at the same time, so that the temperature difference between the pump body and the conveying medium is below 50 centigrade.(8) the oil must be sufficiently dehydrated before being introduced into the oil pump.

Q: What is a positive displacement pump? He Weizheng displacement?: Includes a pump housing (10), a pump chamber (24), the pump chamber has an entrance channel (21) and an outlet check valve (17) export control channel (28), a displacement member (13), the definition of the pump cavity in a direction of movement in (24) and in a stroke section in the pump cavity (S) in reciprocating motion

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: What is the liquid pump? What are their categories? What are their strengths and weaknesses?: The air driven liquid pump adopts compressed air driving method, and has the following advantages:The pressure can be adjusted by manual pressure control valve or air control valveIt is driven by air and is especially suitable for explosion protection applicationsAble to achieve pre-set final pressureAutomatic pressure relief by pumpLong term conservation without consuming energyWhen holding pressure, medium will not overheatThe utility model has the advantages of convenient installation and low maintenance cost, and only needs to connect the gas source, the inlet pipeline and the pressure pipelineReliable operation, low maintenance cost and little noise at the time of operation

Q: Pump operator's responsibility 10Sharing the rules, responsibilities, etc..: 3. master the operating rules of the pump operation, and make sure the pump position is reasonably determined. Do a good job of site investigation, find out, pay attention to.4. master the working principle and basic technical parameters of the delivery pump. Obey the command of production dispatcher to ensure the completion of production tasks.5., according to the number of tanker at the scene, determine the pumping speed, in order to ensure the continuity of pouring.6. normal pumping, the discharge rate should be uniform, to prevent uneven discharge, resulting in pressure pipe gas plug, and thus lead to pipe or pipe explosion accident.

Q: How many concrete pump tube diameter: The pump tubing diameter is 125MM general concrete or mortar pump tube diameter is 80MM fine stone

Q: What are the main performance parameters of the pump?: RPM revolutions per minute. In N, the unit is R / minThe power delivered by the shaft power prime mover to the pump shaft. In P, the unit is kW.The ratio of useful power to shaft power of an efficient pump. With ETA said. It is an indicator of the degree of perfection of the pump in terms of hydraulic power

Q: Do you have a suction pump higher than 9 meters?: This screw self-priming pump suction process can be more than ten meters or more, my family is using this
