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.

Q: Why does the centrifugal pump close the pressure to start?
Therefore, the operation rules of multistage centrifugal pumps require that the inlet valve be opened before opening, and the outlet valve is closed. However, the export valve closed time can not be too long, because at this time the medium in the pump cycle, the medium temperature gradually increased, easy to cause mechanical seals, due to lack of lubrication friction and wear or damage.
Q: What are the causes of pump shock?
3. the water pump set screws loose, adjust the concentric, fastening the foot4. pump into foreign body, open cover overhaul5. the flow is too large or too small, adjust the equipment to control the water output
Q: What does "anti pump" mean in pump operation?
Function: anti pump effect when used for pumping concrete pumping occurs overpressure, the pumping pressure is above 25MPA, the concrete conveying pipe out of ash, can be understood as the precursor of pipe blockage, at this time should immediately use the anti pump, the concrete from the conveying pipe in the suction into the hopper, thus preventing plugging happen
Q: Fire control center manually start the fire pump directly, multi line control, called straight up line NHKVV-7*1.5, my understanding is: straight line from fire control center
Multi line linkage NHBVR-4*1.5 is a positive pressure blower and smoke exhaust machine fire fighting equipment
Q: What is the lift off the dead center point? This is a straight mark about the water pump. What is the function and the relationship between the design head and the pump head? ThanksWhat exactly is the dead point lift? What's the function of this indicator?
In a dead head will be relatively high, the main downstream equipment and pump, if a dead head high, so the design pressure of the pump needs downstream equipment will be relatively large, resulting in the cost increases, so close a better head lower dead point.
Q: What's the meaning of the pump head in the water pump, please advise, thank you
According to China Wikipedia network, the basic components of the water pump: motor, coupling, pump head (body) and chassis (horizontal).Pump is generally composed of pump body and pump head, in which the pump body refers to the spiral case, impeller, bearing, oil shell and sealing assembly, etc., the pump head refers to the impeller, bearings, oil ring and sealing rotating parts (including shaft), etc..
Q: What is a feed pump?
In general, high lift pumps are required with a front pump (which is similar to the feed pump of the landlord) or a low position;
Q: What are the problems that should be paid attention to when using vacuum pumps?
(1) check the vacuum pump line and the joint site regularly to see if there is any looseness. Turn the vacuum pump by hand and see if the vacuum pump is flexible.(2) add lubricating oil to the bearing body, observe the oil level at the center line of the oil mark, and the lubricant shall be replaced or supplemented in time.(3) plug screw vacuum pump of the water screw, filling water (or lead paste). (4) turn off the gate valve of the water outlet pipe and the outlet pressure gauge and the vacuum gauge. (5) point motor, and see if motor steering is correct.(6) start the motor. When the vacuum pump is in normal operation, open the outlet pressure gauge and the inlet vacuum pump. As soon as the proper pressure is shown, the gate valve is gradually opened, and the motor load is checked.
Q: Why does the centrifugal pump start with a closed valve and the axial pump starts with an opening valve?
Because the characteristic curves of the two are different.The power of centrifugal pump decreases with the decrease of flow rate. When the flow rate is zero, the power is minimum, so the centrifugal pump is started with a closed valve.
Q: Filter backwash pump for what use, what is the principle of work ah?
Regeneration of the filter medium is required to regain the filtration capacity of the medium. The regeneration process is mainly accomplished by the backwashing pump (the backwash pump is not a special pump, referring to the pump for the completion of the process). The working principle is through the cleaning liquid from the downstream of the filter into the backwash pump (alkali, acid and water), reverse flushing filter medium, cleaning liquid discharged from the upstream, this process can be attached to the dielectric surface and internal impurities washed away.
