Q:What are the export pumps packed in cartons?
Our exports are packed in specially made export special wooden cases. The water pump bolts are fixed at the bottom of the wooden box through the anchor bolt hole, then wrapped in plastic bags, and then sealed.
Q:Water pump motor often inlet
I don't know what the pump is upstairsThe ordinary centrifugal pump inlet outdoor installation, in order to prevent the motor fan end can be installed in the end of 0.5 with the maple leaf canopy, the sheet can be, the supporting leg can be installed in the wind leaf cover screws; if your motor output is water, and the output end of the motor bearing can be installed with the same motor shaft the outer diameter of the rubber water retaining ring (the market for rubber seal should be easy to buy)Submersible pump (pump) often water, you should consider replacing the good points of the mechanical seal, such as to choose oil resistant, acid and alkali resistant, selected according to the transmission medium and the pump itself, if you can confirm the correct, check whether the pump shaft bending, made into concentric mechanical seal damage. And check whether the casting on the motor side is defective or not;Choose a higher level of protection of sewage pump, preferably in the pump leakage probe, float switch, overload, lack of protection, generally will not burn the motor
Q:Level 200 meters distance, elevation 30 meters, how much lift water pump?
Lift is usually used to overcome vertical height and pipe loss. Now you can determine the vertical height of 30 meters, 230 meters long pipeline losses but you lack of data not calculated. With the following conditions can be calculated: 1, flow; 2, pipe diameter; 3; pipeline material; 4, elbow number; 5, valve types and quantities.
Q:How many kinds of pumps are there? What are the advantages of soft start?
Soft start is prepared, hard start is not prepared, the machine suddenly can not stand! Ha-ha
Q:Water pump mutual switching device
You can refer to the DCL and DCS microcomputer access control system, you can achieve the purpose of remote control. Specific installation methods can be found in local instrument engineering inquiries.
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:The diving pump in the aquarium stops and stops on the goldfish
Generally do not close the filter at night, at 56 in the morning when the most likely hypoxia. The sick fish are all fished out. Fast infection
Q:Why is water pumping cool water is normal, but when pumping hot water pressure and flow are very small?
There may be: first, the water temperature is too high, the impeller damage! But this may not be very likely! Second, but also the water temperature is too high, but may be too high water temperature will be hot water pipe deflated, resulting in no water. Third, it is possible to buy fake and shoddy products!!! Another important problem is that you didn't tell me what kind of pump it was! What forms of work do you have?
Q:What is the difference between a fire pump and a living water pump?
1, fire pump is actually divided into many kinds, such as car, fire hydrant system, spray system, etc., life pump is also, the distinction between them is sometimes difficult to tell the exact. Simply put, the fire pump in its design must meet the corresponding fire requirements, such as pressure, speed, work adaptability, etc., specific requirements can be found in "national standard GB 6245-2006, fire pump Fire, pumps""2, the same function of fire water pump, its price is relatively stable. I personally feel that we must find more manufacturers to understand the reasons for the price difference, and then make a choice.
Q:Three phase water pump rated power 4000W, is three-phase working water pump, the voltage is 380V, how to find the three-phase pump current, and calculation of public
Three phase water pump motor rated power 4000W is the output shaft power, divided by the motor efficiency (general 85%) is the input power, which is often mistaken. The electric power is =4000/0.85=4706WRated current = electric power /1.732x, rated voltage x, power factor =4706/1.732x380x0.8=8.94A (assuming power factor 0.8).The above three answers are all wrong.
