- Q:What is the reason for the overload of the water pump indicator?
- Hello friend, pump overload shows that the water pump current increases, the power supply phase and water pump load becomes larger.
- Q:What's the difference between a cold water pump and a hot water pump?
- Cold water pump is generally packing seal, hot water pump is generally mechanical seal. If the cold water pump is used to transport hot water, the common trouble is that the shaft seal is easy to leak and the water pump is easy to damage. Generally in the design of building water supply and drainage, cold water pump and hot water pump can be selected according to the cold and hot water. Water supply and drainage design manual (common equipment) and pump manufacturers Water Pump samples can be found.
- Q:Why is the water pump smaller than the pipe diameter?
- In order to reduce the water outlet resistance of pump outlet.The statement should be: if your pump has been selected, then the outer outlet pipe caliber than the water pump outlet diameter one.
- Q:What is the reason that the centrifugal pump outlet pressure decreases and the operating current increases?
- See if the impeller problem is loose or something else. Impeller problems are generally
- Q:Pump power ratio design is small, the problem is big?
- Lift and flow to meet the requirements of power, in fact little difference, different manufacturers and brands in the same common effect of different power phenomenon, design principle is on the one hand, the hysteresis loss mechanical loss processing technology is one of the reasons of the differences. Power, after all, does not increase, and does not have a major impact on other lines.
- Q:Should the no-load power of the pump be equal to the rated power?
- We must first clear the meaning of rated power; rated power is called the reference numerical electrical power consumption in the voltage conditions specified, and the actual power consumption of electrical appliances is different in different situations, the pure resistance (such as lighting, electric) as long as the voltage conditions, the actual consumption of electric power close to or equal to the rated power, and for appliances like motor, electric power consumption, not only related with the voltage, but also with the relevant load. For example, someone with 200 pounds of energy, then the person in the condition of small meal, maximum load of 200 pounds, but if you take as long as he is 100 pounds, of course he relaxed, he would not say must bear 200 pounds!You measure the pump power is less than 1200W, first you did not mention your use of voltage is not rated voltage, then you don't want him full load, the suction is far less than 8 meters, there is no mention of whether you send water to 50 meters (Yang Cheng), there may be insufficient voltage, and you have don't need it so much power consumption. Of course, one advantage is that it doesn't burn easily. It is easy to burn if it is used at full load.
- Q:How many pumps does a 50 meter water head use?
- Deep well submersible pump head = dynamic water level to pipe outlet height + outlet pressure + hydraulic loss along courseTherefore, it is necessary to provide the dynamic water level of the well, the required flow rate, the pipe diameter, and the vertical height of the wellhead to the highest point, so as to estimate the pump head.
- Q:Is it illegal to produce aluminium submersible pumps?
- When buying, if you ask for a copper wire or a wire, and don't answer you, it's against the principle of good faith. On the contrary, if you did not ask to buy the water pump with aluminum core, then there is no violation. Because the country does not have any laws and regulations prohibiting the production of aluminum core wire motor, naturally there is no aluminum wire motor as a fake and shoddy products, there is no pre notice obligations.In fact, the aluminum core motor is good, and the price is low, especially in the dry environment of small and medium-sized motors, with good performance. Only used in submersible pumps, because aluminum is easier to damp than copper wire, due to bacteria and other corrosion, and its life is sometimes less than copper wire. But the water pump, aluminum often needs to rewind coil, because of a small submersible pump motor is not good around general scrap.
- Q:What does the lift of a pump mean?
- Lift lift height = water raise height = total lift lift height + water = water is expressed in M by H (m)
- Q:Fire pump room is required to set up water pump control room?
- You can't set it up.If there is a control room host automatic alarm automatic fire alarm system of words (through the pump distribution box can also control) can control the fire pump, if there is no distribution box automatic alarm system you can through the pump room control.Fire pump for fire as the name implies, pump, fire pump is the introduction of foreign products, according to different classification, divided into different types to its sealed, no leaks, corrosion-resistant characteristics, widely used in environmental protection, water treatment, fire departments for pumping all kinds of liquid, no leakage, no pollution is to create civilization workshop civilization, the ideal pump factory and pump type fire control system are similar, only the head and the flow are different. The selection of fire pump should be based on the technological process, water supply and drainage requirements, from five aspects to consider. Fire pump performance and technical conditions meet the requirements of the Atlantic pump standard "fire pump performance and test method" standard.
