Q:What are the categories of pumps?
First, select the pump to meet the requirements of the headThe so-called head refers to the required lift, and not lift the water height, clear this point, the choice of water pumps is particularly important. Pump lift is about 1.15 to 1.20 times the height of lifting water. If the vertical height of a water source to the water is 20 meters, the required lift is about 23~24 meters. When selecting a pump, the pump head should be close to the required head, and the general deviation is not more than 20%. In this case, the efficiency of the pump is the highest, and it is more energy efficient, and the use will be more economical. If the lift on the nameplate is much smaller than the required lift, the pump can not meet the needs of users, even if the water can be pumped, the water is also very poor. But in turn, the high lift pump for low head, there will be heavy traffic, resulting in motor overload, if long time operation, the motor temperature, the winding insulation layer will gradually aging, and even burning motor.Two, select the appropriate flow pumpWater pump flow, that is, the amount of water is generally not too large election, otherwise it will increase the cost of water pumps. Should be selected as needed, such as the use of the user's family self-priming pump, the flow should be chosen as small as possible; if users use the submersible pump irrigation, you can properly select a larger flow.
Q:Does the IP55 indicate the lift on the water pump nameplate?
IP is INGRESS PROTECTION, that is, protection level,IP protection class is composed of two numbers, first numbers, from the lighting level to prevent intrusion of foreign objects, second numbers represent the tightness of anti moisture, waterproof lamp intrusion, the larger the number the higher the level of protection.Therefore, the pump IP refers to the pump with its own motor dust and waterproof level
Q:In the design specifications, for example, the water pump requirement is two. What does that mean? Can 3 pumps be opened at once?
Use 2 units and reserve 1 units. You can open 2 at the same time. Can three drive at the same time, depending on your water pipe layout, whether there are three sets of pipes, yes, three units open at the same time.
Q:Stop the engine immediately and stop the circulating pump and the condensate pump. What's the harm to the turbine?
Then look at what is the circulating water pump and condensate pump users, circulating water with oil in the oil cooler then, condensed water supply pump seal water, water pump can't pump up, how will you know.
Q:Why is the minimum liquid temperature allowed at 2 DEG C instead of 0?
Is zero freezing?
Q:What are the quota items for the complete pump installation?
It can be divided into the following sections:1. pump installation platform, to obtain concrete and reinforced section (if any)2. anchor bolt installation: cap construction reserved bolt mounting holes of the anchor bolt installation hole grouting taking, (may be incorporated into the 1), and the damping piece related item;3. pump installation: installed in the installation of fixed item taking pump, check the wiring and debugging section, the first cable.The above is only a rough expression, the specific problems are flexible.If you still don't understand, you can contact me.
Q:When the pump is connected in parallel, will the head and flow change?
2 pumps parallel, lift the same, pump head is not stacked?;Answer: the head can not be superimposed, that is, a lift and a pump, but the pumping speed (flow) is two times a taiwan.2 pumps in series, the same flow, pump head is not stacked?.Answer: the head can be superimposed, that is, the pump head is two times as much as a pump, but the pump speed is the same as that of a pump.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 pumps does a 50 meter water head use?
Well pump head selection for pump + water depth height (water pressure) + head loss, head loss of water system is not complicated with 3-5 meters can, refers to the depth of pump well pump down into the well depth, generally shallow wells is down to the bottom, is based on deep well pumping well test data to determine the position of the pump.
Q:2 pumps parallel, lift the same, pump head is not stacked?
2 pumps parallel, lift the same, pump head is not stacked?;Answer: the head can not be superimposed, that is, a lift and a pump, but the pumping speed (flow) is two times a taiwan.2 pumps in series, the same flow, pump head is not stacked?.Answer: the head can be superimposed, that is, the pump head is two times as much as a pump, but the pump speed is the same as that of a pump.
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.
