    Please notify materials of major components in your order. If you have any question, please contact to us without hesitation.

  • Construction: The pump is horizontally installed. The inlet and outlet are under the split surface and in the perpendicular direction with pump central shaft-line, during the course during the course of installation, you needn't to remove the motor and the pipes.
    Type SLA is vertically installed the inlet and outlet at a same center line and the case and cover are in the perpendicular direction.
    Bearing: Both end of the pump are rolling bearings (type 24SA_18, 16SA_90 could use the sleeve bearings)to support the rotor, the lubrication oil is dilute oil or grease.
    Materials of tolerance: The material s of tolerance is cast iron or it can be changed into cast steel and bronze, but it should be signed in the order.

Q:How many square cables does the submersible pump for 7.5KW need?
According to current I=13A, it is estimated that the cable is less than 10 square meters, so the cable cross section can be calculated at the ampacity of 5A per square meter. The square section of the cable is =13/5=2.6 square. According to the specifications series, optional 2.5 square aluminum cables. When the cable is longer, it is safer to choose 4 square aluminum cables.
Q:What is the "variable" of a variable pump?
Variable pump variable refers to the flow can be changed to distinguish from the constant flow of quantitative pumps.
Q:Fire pump and shower pump flow head selection, high resolution.
Selection of flow head of fire pump and spray pump:1, the volume is greater than 5000 is less than 10000, the minimum water consumption of indoor fire hydrant is 10L/s
Q:Does the control cabinet of the fire control pump need to be related to the fire control room?
Automatic sprinkler, which is mostly used in this device or high water tank, the whole set of equipment must meet the most unfavorable point (the farthest the highest point of water) water pressure of the faucet.
Q:What happens when a centrifugal pump is selected?
First of all, the performance curve of the centrifugal pump is similar to the track of the train, and the train can not run away from the track.Secondly, the performance curves of centrifugal pump mainly include flow head curve, efficiency flow curve, power flow curve. When the pump is ready, the curve is fixed. In practical application, after determining the flow rate, the corresponding lift head, efficiency and power (relative to density) are determined. General requirements for centrifugal pump operating in the vicinity at the highest point of efficiency, the efficiency of the flow curve is similar to parabola, so if the actual operation condition deviated from the rated point, whether large or small, will cause the decline in pump efficiency (generally rated value is less than 15%), increased operating costs.
Q:How many concrete pump tube diameter
Different pipe diameter is different, most of the 125, there are 150. Now we have the smallest pump on the market, with a pipe diameter of 100.
Q:What are the characteristics of the piston pump?
main features 1 、 double plunger structure, small pressure pulsation, long life of gem ball.2 、 imported precious stones and precious stones to ensure accurate flow.3, through the RS232 interface and computer communication, can be directly controlled by the computer.
Q:How to distinguish the flow and displacement in the hydraulic pump? What's the difference between the two?
The unit of displacement is the milliliter. How many milliliters does the pump rotate per circle? The displacement is the pump, the individual,The unit of flow is generally a liter, a figure added to the displacement of the pump over a period of time,
Q:Constant pressure pump working principle
15MPa. 20MPa means that if you enter the 20MPa, the variable mechanism will work, and the flow at this time automatically matches the load. 20MPa used to supply the fuel by maximum displacement.
Q:Harm of air pump and pump
Minimum starting current when centrifugal pump of such a small impact on the grid but long closed operation will make the liquid in the pump to the pump overheating temperature is too high will lead to the problem of the seal to a certain temperature will cause deterioration of oil bearing bearing caused by excessive wear and even bite dead
