FAQ

What are the main performance parameters of the pump?
The amount of liquid supplied by a pump in unit time. Volume flow Q, unit m3 / s. There is mass flow G, unit is kg / s.
Why is the flow of the pump too small will occur cavitation phenomenon?
This is because the impeller of the centrifugal pump rotating speed under the drive of the prime mover, when the valve opening decreases, flow rate is too low, can not be taken away by the friction heat generated by the impeller and the liquid completely, make the temperature of the liquid inside the pump. Thus causing liquid vaporization, forming cavitation. Especially in the power plant, the boiler feed pump is more remarkable. Therefore, when throttling regulation, we should set up recirculation system, increase the output flow of the pump to prevent cavitation. When the feed water rate is reduced to 1/3 of the maximum flow rate, the recirculating gate shall be opened so that the flow of the feed pump will be increased properly to ensure that the liquid temperature in the feed pump does not rise.
Why adjust the centrifugal pump outlet valve can adjust the flow? What are the advantages and disadvantages of this method? Is there any other way to regulate the flow of the pump?
The centrifugal pump at a fixed speed, the head is fixed, adjust the outlet valve to adjust the diversion area
How many kinds of pumps are available and the operating principles of various pumps?
There are many kinds. See what divides.According to the working principle can be divided into: the power type pump, also called pump or impeller vane pump, depending on the dynamic effect of the rotation of the impeller on the liquid, the continuous energy transfer to the liquid, the liquid kinetic energy (mainly) and the pressure will increase, then converting kinetic energy into pressure energy through the discharge chamber, and can be divided into centrifugal pump, axial flow pump, partial flow pump and vortex pump etc..
Types and differences of pumps
Classification and working principle of pump by structureClassification of pumpsInvolved pump standard product types are also very much, a centrifugal pump, metering pump, screw pump, reciprocating pump, hydraulic pump, submersible pump, oil pump, water pump, pressure test pump, vortex pump, cryogenic pump, vacuum pump, roots pump, molecular pump, gear pump, mud pump, corrosion-resistant pump deep well pump, water pump, mixed flow pump, axial flow pump, boiler feedwater pump, liquid pump, injection pump, chemical pump, pump plugging and no leakage pump, plastic pump, fire pump and so on, there are many. Its name is divided according to some conventional classification methods such as pump vane pump volume, pump etc., some are divided by purpose such as sewage pump, pump and other health, some names are more random as diffusion pump, liquid nitrogen pump. As long as the production of this product, with standard requirements, through a certain application and approval procedures may produce a new The standard, but sometimes the content also has a repeated cross, quite. The domestic and foreign standards, the domestic standard is more than the number of foreign standards. In general, such as centrifugal pumps are widely used, the production history of the pump more standard (total standard centrifugal pump up to more than 100). As new standard pump leakage pump this rapid development is relatively small. This paper introduces the structure and working principle of the pump according to the classification of the
What is the liquid pump? What are their categories? What are their strengths and weaknesses?
The pump is constructed by connecting large diameter gas piston with small diameter hydraulic piston. The two piston area ratio produces a pressure ratio, and the maximum output pressure can be calculated by the pressure ratio. High pressure ratio produces high outlet pressure. You can set the outlet pressure through a simple gas pressure reducing valve. Pressure ratio * gas drive pressure = output pressure.
What does "dual purpose" of water pump mean? Please expert advice
2, the pump must pay attention to maintenance after use, for example, when the pump is used up, the water pump should be put clean, it is best to remove the water pipe, and then rinse with water.5, the water pump on the tape should be removed, and then rinse with water after drying in the light place, do not put the tape in the dark damp place. Water pump tape must not be stained with oil, not to tape coated with some sticky things.6, to carefully check whether there are cracks in the impeller, the impeller fixed to the bearing on whether there is loose, cracks and loose if the phenomenon to be timely maintenance, if the water pump impeller should also be above the earth clean.
How about the depreciation of vacuum pumps?
(three) appliances, tools, furniture and so on related to the production and operation activities, for 5 years;(four) aircraft, trains, ships and other means of transport for 4 years;
