Q:Types and differences of pumps
Depending on the flow of the fluid, they can be subdivided into the following:Classified centrifugal axial flow type mixed flow tubular flow typeThe basic principle of impeller centrifugal force generated by the high-speed rotation of the fluid energy rotary vane extrusion propulsion of the fluid increases the pressure to get the energy mix and energy principle of centrifugal and axial and centrifugalSuch as: central air conditioning centrifugal fan, central air conditioning or cold storage axial flow water pump, mixed flow water pump, domestic air conditioner, indoor fanWorking principle of pump and fanI. the working principle of centrifugal pumps and fansThe centrifugal force generated by the high-speed rotation of the impeller fluid power, namely fluid through the impeller, pressure and kinetic energy can be improved, which can be transported to the height or distance. The impeller is arranged in a spiral shell, when the impeller rotates, the fluid axial inflow, and then turn 90 degrees into the impeller and the radial outflow impeller. Continuous rotation of the impeller inlet in the form of vacuum, so that the fluid continuously by the pump suction and discharge.
Q:Piston filling and peristaltic pump filling which precision is high?
These two pumps are used as a metering pump to use, so the accuracy is to be on a par with the peristaltic pump has more advantages than the piston pump is the largest energy fluid conveying there are particles, and the piston pump is smaller than the peristaltic pump pulse, so we need to choose according to the material characteristics you need to transport.
Q:Centrifugal pumps for normal operation, is it reasonable to install valves on their inlet lines?
Reasonable, no valve, how to debug, overhaulGenerally installed on imports of valves of relatively large Cv value
Q:What is the relationship between the minimum suction vacuum of a pump and the required cavitation?
When the vacuum pressure is called vaporization pressure, cavitation is more than the surplus energy of vaporization pressure at the unit weight of the liquid in the pump suction port of the unit, with mark. The absorption process is to NPSH delta H: pump suction fluid allows the vacuum pump installation height is the unit of rice.
Q:What happens when a centrifugal pump is selected?
First of all, the performance curve of the centrifugal pump is similar to the track of the train, and the train can not run away from the track.Secondly, the performance curves of centrifugal pump mainly include flow head curve, efficiency flow curve, power flow curve. When the pump is ready, the curve is fixed. In practical application, after determining the flow rate, the corresponding lift head, efficiency and power (relative to density) are determined. General requirements for centrifugal pump operating in the vicinity at the highest point of efficiency, the efficiency of the flow curve is similar to parabola, so if the actual operation condition deviated from the rated point, whether large or small, will cause the decline in pump efficiency (generally rated value is less than 15%), increased operating costs.
Q:What does the pump mortar do?
In order to effectively reduce the flow resistance of concrete and pipe, to avoid obstruction caused by pipe sticking and to achieve normal pumping, and its role is generally only pumps.
Q:Why is the submersible pump tripped on an electrical switch?
Calculate or refer to the water pump nameplate that the normal operating current, according to this data exchange switch.2) with 500V shaking table, measuring the cable, motor insulation is in line with the requirements
Q:5 floor water pressure is too low, what kind of water pump is better?
The location of the pump is too far away from the pumping pool, the suction of the pump is not enough, cavitation phenomenon, pumping water, this water pump manufacturers, the pump will be placed in a reasonable position
Q:What are the advantages and disadvantages of the pump control system and valve control system in the hydraulic system?
Large pump control valve controlled energy consumption at least 30% reason is that there are serious throttling loss of a throttle valve control system of severe fever but simple structure and low cost which is why now valve control system still occupy the main market reasons.Pump control system with complicated structure especially when serious nonlinear control unsymmetrical cylinder control effect is not ideal, but the biggest advantage is energy-saving and low fever America professor Monika points out that using the pump control system of hydraulic excavator energy efficiency compared with the valve control system can be improved by over 46% but costs are high. But in control, the three pump invented by Professor Quan LONG of China is a good solution. LZ can find the invention patent or find his paper on sage. It seems that there are three or four SCI about this 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.
