Q:What are the categories of pumps?
As long as you see, you need flow, lift, power
Q:Who can tell me such water pump medium flow direction should be what kind of, from left to right, or from right to left, is low into the higher?
In the picture, to the right is the entrance, the left is the exit, the water pump inlet channel section area generally will be bigger than the export.
Q:Why does the GB/T3216 specify the pump performance tolerance as positive and negative?
Tolerance coefficient is due in the manufacturing process, will, so each pump products are possible shapes and sizes do not conform to the pattern of the situation, and ensure the test results in the value (operating point) when compared, should be allowed to have a certain tolerance. It should be noted that these tolerances are only relevant to the actual pump and do not involve test conditions and measurement uncertainties. If the pump at a certain working point (the same lift) standard (Design) flow of 20m3/h, the actual flow of 22m3/h, indicating that the pump in the design process has unreasonable place, resulting in waste of power. Deviations from the manufacturing process usually have no positive deviation.A pump is a machine that transports liquids or pumps liquids. It will be the prime mover of the mechanical energy or other external energy transfer to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids. Pump performance of technical parameters are flow, suction, lift, shaft power, water power, efficiency, etc.; according to the different principles of work can be divided into volume pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.
Q:How many kinds of pumps are there? What are the advantages of soft start?
The starting modes of water pump are direct start, star triangle start, reactance start, soft start, step-down start and frequency conversion start.1, direct start, generally suitable for small power motors, generally only in the following 15kw pumps, cheap;2, the buck start is the star triangle conversion start, that is, the start is accelerated two times to reach the rated speed, generally in more than 18.5kw pump use, moderate price;3, soft start is gradually increased to the rated speed, the impact on the pump is very small, the price is relatively high, is generally 3 times the buck start;4, the highest frequency conversion is started, in addition to the advantages of soft start, but also can be set at any speed work, energy saving has significant effect.Advantages of soft start:1, the output torque of the motor can meet the requirements of the starting torque of the mechanical system, ensure smooth acceleration, smooth transition, and avoid the impact of destructive torque;2, the starting current to meet the requirements of the motor capacity, to avoid motor heating, causing insulation damage or burnout;3, make the starting current to meet the grid power quality related standards requirements, reduce voltage sag amplitude, reduce the higher harmonic content.
Q:What motor does the pump use?
Pump should use special water pump motor.Pump motor (pump motor) according to the structure classification, should be divided into horizontal motor and vertical motor. Because of the work characteristics of pump starting torque is relatively small, the starting frequency is relatively small, relatively long time continuous operation and other characteristics, so the majority of pump motor asynchronous motor cage rotor or synchronous motor.
Q:How to measure the temperature of pump body?
Pump body temperature in general, with the hands feel good, and when the hand arrived, can not accept, the pump will have a problem. Specific by their touch cooked.
Q:The water burst how to repair?
This is used by welding and making AB calls
Q:What's the function of the engine pump?
In simple terms, the engine is cooled to prevent the engine from getting too high.Working principle:Drive the pump bearings and the impeller to rotate through the pulley, the coolant pump impeller is driven to rotate together, under the action of centrifugal force was thrown to the edge of the pump shell, and produce a certain pressure, and then from a channel or pipe outflow. At the center of the impeller, the pressure is lowered because the coolant is thrown out, and the coolant in the water tank is sucked into the impeller by the water pipe and the pressure difference between the inlet of the impeller and the center of the impeller to realize the reciprocating circulation of the cooling liquid.
Q:What does the pump lift mean?
The pump head is the parameter you must know when you buy a pump, that is, the height of the pump.To buy a pump, I think the Heathrow pump is OK. I bought it earlier this year. It's not bad yet, but the quality is pretty good.
Q:What is the relationship between pump power, lift and flow?
N= QH/1000 gamma ETA gamma, severe liquid, cattle - ETA / m3; efficiency; N- kW; H- head, power meters;Q- volume flow per cubic meter / sec.
