5. RFQ

1> What's the difference for CHL and CHLF(T) type?

    CHL pumps have an inlet and outlet chamber which is made by stainless steel. CHLF(T) is just the section type. 

2> Do you have any variable motor for these pumps?

     Yes, we have. For the variable motor, the frequence can be changed as the customers' request. If the range is between 30~50Hz, the fan can be just connected with the shaft. And if the frequency is below 30Hz, then the fan has to have another separated power. The variable speed motor would be used for solar energy or some other similar situation with the unstable power. 

3> How about the Delivery time?

     Actually, this would be depending on the quantity. If it is just small order, 1 week would be fine. For bigger quantity, the delivery would be also less then 20 days. But for the varible speed ones, it will be taking some more time, normally it will be more than a month.  

4> Is it really necessary to fit a bleed valve for the boxes?

     It is always best to have a bleed valve as the gas produced by the fermenting sewage is potentially hazardous.

5> If I increase the power of the motor, must I also increase the power of the inverter?

    You must select the size of converter that allows maximum absorption of the electric motor.

6> Do you have pumps with grinders?

    Yes, the WQ models.

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:How should the water pump breaker be selected?
Tell you a way, then go to the election, mainly to see his rated current to choose.The most general calculation of a KW==2 current (380V3 phase) 11KW==22 current, and then enlarge 1.2 times, that is, the current of the circuit breaker is selected to 25-30A. If it is started directly, zoom in to 1.5 times. Yes, no problem!! In addition, the 37KW 64 current short circuit selector 80-100A is ok.. Similarly, 4KW following unification can be done using 10A15A
Q:Sewage treatment plant design how many pumps should be selected, head how to calculate the maximum design flow is 833M3/h
Pump selection to consider the flow, lift, diameter and power, but also with reference to the actual workload, the design quantity is 1666, how much can actually achieve? Head to refer to pipe length, height difference, elbow number, such as flow in more than 800 of the pump, lift at 35 meters, can generally meet about 200 of the pipeline work needs.
Q:What does "ETA" mean in the selection of pumps?
NPSH refers to the cavitation, the pump is the technical parameters
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:TDH what units are present in the pump parameters?
Answer: TDH stands for single pole double suction horizontal chemical process pump, suitable for conveying clean or containing micro solid particles of ultra low temperature or high temperature liquid medium, is also particularly suitable for conveying strong corrosive medium. All facilities for horizontal installation are available.Mainly used:Petroleum smelting plant, petroleum conveying equipment and pump used in petroleum deep processing devicePump for coal chemical processPumps for water and desalination systemsPumps for fuel coal fired power generation equipmentSewage treatment and environmental protection pumpStructure characteristics:Pump in the horizontal opening, suction and discharge pipeline is located in the lower half of the pump body. The disassembly and replacement of the wearing parts and the replacement of the rotor parts can be performed without disassembly of the pipe.Double suction impeller, high efficiency, good cavitation performance, axial force is basically balanced.Rigid axle shaft and bearing, double end support, small deflection, small vibration, low noise, oil lubrication of rolling bearings with oil ring, constant level oiler automatic control level, and can get automatic compensation, radial thrust ball bearings back-to-back bear residual axial force.The sealing ring of the shell is provided with a stop and a step, and is arranged on the pump body and the pump cover, so that the assembly and disassembly are convenient.
Q:Pump frequent start will reduce the service life, I ask what kind of frequency is called frequent start?
How to define this frequently, this can only say, for example, the life of the switch is 60 thousand times, once every hour you move, it can be used for a long time, and that if you move one minute, it would not necessarily for long.Pumps frequently start the first self wear problems, as well as the impact on the pipe network, especially the soft connections.Water pump if the frequency of use or time, it is recommended to adopt: variable frequency constant pressure control.
Q:The role of impeller in water pump
Pump impeller through the motor to drive rotation, so that the medium (water) by centrifugal force or lifting force, so that the medium has mechanical energy (kinetic energy)
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?
Low inlet and outlet
Q:Ask the principle of fire truck and pump adapter
Fire engines have their own hoses. I've seen them. They usually have hydrants. They take water from them. If they don't work, they have their own water
