Q: The function of centrifugal pump
6. Stuffing box mainly consists of packing, water seal ring, stuffing box, packing gland and water seal pipe. The function of the stuffing box is mainly to close the gap between the pump shell and the pump shaft. The water in the pump is not allowed to flow outside and the outside air is not allowed to enter the pump. Always keep the vacuum in the pump! When the pump shaft and packing friction heat, it is necessary to rely on water seal to control water into the water ring, so that the filler cooling! Keep the pump running properly. Therefore, in the water pump running inspection process, the stuffing box inspection is to pay special attention to! In the operation of about 600 hours, it is necessary to replace the packing.
Q: What does the pump mortar do?
Concrete pump before the need to transport water and pump pump material, dredge pipeline. In accordance with the technical specification for concrete pumping construction (JGJ/T10 - 1995), pumping concrete, pump mortar generally use cement slurry
Q: How many millimeters is the diameter of the water outlet of the four inch pump?
If it is a centrifugal pump, the nominal diameter of the outlet is less than 4 inches, there is a conical short tube to enlarge the standard 4 inch outlet flange, from here, is the standard 4 inch flange connection.
Q: What is the principle of a turbopump?
A machine that converts the energy contained in a fluid medium into mechanical work [turbine]. Also known as turbines, turbines. Turbine is the transliteration of English turbine, derived from the Latin word "turbo", meaning "rotating object". The working conditions of turbines are different from those of the employed ones, so their structure types are various, but the basic working principle is similar. The most important component of a turbine is a rotating element (rotor or impeller) that is mounted on a turbine shaft and has blades uniformly arranged along the circumference. The energy of the fluid is converted into kinetic energy in the flow through the nozzle, and when the fluid passes through the rotor, the fluid impacts the blade and drives the rotor to rotate, thus driving the turbine shaft to rotate. The turbine shaft drives the other machinery directly or through the transmission mechanism, and outputs mechanical work. According to the turbine working fluid used can be divided into different turbine (used as a power source of Hydropower Station) and steam turbine (used in thermal power plant, ship propulsion), gas turbine (used as jet propulsion, ship power, and power plants, with a small peak load power station and air turbine (only) as a small power).
Q: What is the relationship between the minimum suction vacuum of a pump and the required cavitation?
When the pump is working, the liquid at the inlet of the impeller, due to a certain vacuum pressure will produce steam, the vaporization of the bubble in liquid particles under the impact of movement, the impeller and other metal surface erosion, thereby damaging the impeller and other metal
Q: Bolus dosage of infusion pumpWhat is the purpose of the pill dose control in the special safety standard for infusion pumps? If the risk is not properly controlled, what is the degree of risk? And how can the open infusion pump be used in this regard?
Four) release bolus dosage method can use automatic release and manual release two ways, the key is to alarm after the infusion must be stopped(five) any kind of pill dose release are not restricted to replace the pill. The total dose limit for in pipe blockage after pill agglomeration process will remove blocking accident, this time will be the rapid infusion of pill dose concentration into the patient's blood, if the total dose pill does not get test and limit, rapid infusion of this accident it may have unimaginable consequences.(six) supplies open type infusion pump overflow on the domestic market for pill characteristic parameters of consumables simply without testing and limitation. Therefore, the risk of accidental pill has become one of the residual risk of open type infusion pump supplies the most deadly.
Q: Why is the flow of the pump too small will occur cavitation phenomenon?
Throttling regulation is to change the opening of the valve to change the flow of the pump, that is to say, to change the characteristic curve of the pipeline. The commonly used to regulate the flow of exports, because the entrance throttle makes reduce the inlet pressure caused by cavitation danger.
Q: How accurate is the metering pump?
In addition, when the oil supply is too large or the pipeline pressure rises unexpectedly, the volume of the liquid in the hydraulic chamber can be changed, thereby affecting the stability of the flow and reducing the metering accuracy of the pump. In order to solve the problem of how to stabilize the measurement accuracy of metering pump metering pump flow, how stable, the three valve device. The so-called actual refers to the combination of three functions including compensation, discharge and safety protection device or device supporting the hydraulic chamber, according to its action principle is different, is divided into automatic compensation and forced compensation two three valve device.
Q: What are the differences between the sewage pump and the clean water pump?
Sewage pump is a pump and motor conjoined, and at the same time submerged into the work of pump products, and general horizontal pump or vertical sewage pump compared to the sewage pump compact structure, small footprint.The water pump is for the transport of water and physical and chemical properties similar to water and other liquids used, suitable for the industry and the city water supply and drainage, water pressure high-rise buildings, garden sprinkler, fire booster, long-distance transportation, HVAC refrigeration cycle, irrigation, bathroom, cold and hot water circulation pressurization and equipment.
Q: What is the difference between centrifugal pump and self suction pump? Which is better?
In order to prevent the filling liquid into the pump shell because of gravity flow in the low groove, in the pump suction pipe at the entrance of a non-return valve (valve); if the location of the pump below the liquid level in the tank, then start without irrigation pump.Self-priming pump is a self-priming centrifugal pump, centrifugal pump is a kind of.Specific choice of a pump, depending on your specific parameters and conditions of use.
