Q:Submersible pump and self-priming pump which is easy to use?
Pump generally installed at less than 7 meters from the water surface, if not meet this requirement, have to use submersible pumps, such as deep wells. Submersible pump is obviously not good, easy to malfunction, have to use.Self-priming pump is mainly convenient, but the performance is lower than the general centrifugal pump.There are both advantages and disadvantages at the same time, which is not easy to use.The key is where to use and how many parameters............
Q:About water pump selection
Domestic I do not understand, only know that you dock water, it is best to use sea water pump, or allow manufacturers to do your anti-corrosionVille, Grundfos.Lift up, I'll do it. 30m is pretty muchThe self-priming pump is OKWhich brand do you want to use? Just call them directlyLet them count it for you and then type itFirst know about yourself, generally know a power head water quantity on the line
Q:My fish tank pump is deep enough, it doesn't bubble up. Without oxygen supply, but it can filter. Does it damage the pump itself?
First tell you the pump not bad, just can't carry oxygen rinse, now he is equivalent to a 2 in a filter of the submersible pump, without any damage to the pump itself, three in one pump is actually in the 2 water outlet and air pipe, pressure by fluid flow is the principle of position the smaller the air drag, now a large pressure, oxygen loss of function, but the pump itself, his work without any change, so do not burn, rest assured it
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:A direct type pump model with the coupling type, what is the difference?
This you can Baidu ah, otherwise it is not professional staff, it is estimated that will not be too clear
Q:In the design specifications, for example, the water pump requirement is two. What does that mean? Can 3 pumps be opened at once?
May not。Design is in accordance with the "two prepared" design, opened two units, has been able to meet the water supply requirements. And the electrical control parts are in accordance with the opening of two units, has been unable to meet the opening of 3 power distribution needs. The standby pump is only replaced when the running pump is out of order or needs downtime to maintain the water supply.
Q:Explore the flow of water pump production process is like?
The main flow of water pump (take centrifugal pump as an example):Technical determination of Drawing > raw material storage > mold preparation > casting moulding > machining > parts experiment > Assembly > performance experiment > painting packing > storage.Here are a few key steps:1) the technique determines the graphMainly the work of designers. Generally according to the parameters of the pump (flow, lift, cavitation, efficiency, etc.) to determine the specific speed of pumps, impeller form, impeller size, impeller material, pump body, pump shaft and so on. One of the most important thing is to draw the impeller woodenpatterns.2) die preparationThe mold is mainly composed of workers according to the water pump impeller woodenpatterns production model.3) casting moldingThe casting molding sand is made on the base of the mould.4) machiningWater pump parts processing, because it has hydraulic flow channel, in considering the positioning clamping standard, must find the correct flow channel of the correct position. Avoid assembly, resulting in water pressure chamber and impeller flow channel skew, dislocation, uneven gap, or even rub, affecting product quality. In order to ensure the accuracy of parts manufacturing, it is necessary to design the appropriate tooling, and reasonable arrangements for technological processes, control process factors.
Q:Why can't sprinkler system and hydrant system share water pump in fire fighting system?
The design code of sprinkler system GB 50084 - 2001 (2005 Edition) stipulates that the sprinkler system shall be provided with an independent water supply pump, that is, the water pump shall not be shared with the hydrant system. The aim is to ensure the reliability of the water supply and prevent interference.See the code for design of automatic sprinkler system, GB 50084 - 2001 (2005 Edition), 10.2.1 and the corresponding provisions of the following interpretation.
Q:The water burst how to repair?
The general water burst positions for the pump body, pump cover, if not very serious welding can be used to trap, at which point the attention electrode material, most of the water pump are cast iron, so the welding difficulty is not small.If it has become deformed or has split into parts, replace it.
Q:Why is the water pump usually used multi-stage pumps, while the circulating pump is usually a single-stage pump?
Mainly determined by the function of the water supply pump and the circulation pump.Replenishment pump is mainly to supplement the loss of the system, so the general flow is smaller, larger head, single pump water model in a small flow situation, many are not up to the required head, can only use multi-stage pumps.Circulating pumps are generally large flow, low lift, heavy efficiency, economic operation, and hydraulic model point of view, are single-stage pumps more appropriate, especially single stage double suction pump.
