Description
Singlestage double suction,horizontal firefighting pump set is newly developed according to market needs.Its executive standard is GB6245《Fire pump》,and the most advanced hydraulic model is applied,combining with the characteristics of double suction pump.It is high efficient and energy-saving,reliable performance,easy to install and use.It is used to transport clean water or liquid with physical and chemical property similar to clean water.Max temperature of liquid can not exceed 80℃.
Applications
It has been widely used in fire fighting and living water supply of industry the residence buildings.

Capacity：30-200L/s
Head：0.3-2MPa
Rate of rotation：2980r/min、1450r/min
Power：2.2-160kW
Two seal types: stuffing seal or mechanical seal
Structural Characteristics
Both inlet and outlet of XBD-S type pump are below the pump’s axial central line.They are perpendicular with axial line and horizontally placed in the middle of pump casing.There is no need to remove inlet,discharge pipeline and electric motor(or some other motors).The pump rotates clockwise from the direction of the coupling.The pump which rotates anticlockwise can also be manufactured according to the requirements,but it should be specified when ordering.
XBD-S type pump is mainly made up of pump casing（1）,pump cover（2）,impeller（3）,shaft（4） and double suction seal ring（5）,shaft sleeve（6） and bearing（15）,etc.Except that the material for the bearing is first grade carbon steel,the remained are all made of cast steel(See the structural drawing of pump).
Pump casing and pump cover compose an impeller’s working room.The installation vacuum gauge and pipeline bolt hole on the pressure gauge are designed for the inlet and outlet flange.After the static balance test on the impeller,it is fixed with the shaft sleeve and sleeve nuts on both sides.The axial location can be adjusted through the sleeve nut.The impeller’s axial force makes use of the symmetric layout of its vane to keep in balance.The rest little residual axial force is borne by the bearing at the shaft end.
The pump is supported by two single-row radial ball bearings.The bearing is installed inside the bearing body at both sides of the pump casing,and lubricated with solid lubricant.The double suction seal ring is used to reduce the amount of leakage of water at the pump impeller.
Pump is directly connected with the electric motor through elastic shaft coupling.(If the transmission with rubber belt must be applied,a support shall be mounted in addition.)
The shaft seal adopts soft packing seal and mechanical seal.In order to cool down the lubricant seal chamber and also to prevent air from leaking into the pump,a water seal ring is mounted among the stuffing.While pump is running, slight amount of high pressure water passes through the concave groove on the centrally-split surface of pump cover into the packing chamber,which functions as water seal.
- Q: What are the uses and precautions of magnetic pumps?
- 2, when the suction surface above the pump axis, before starting the valve can open the suction pipe, if the aspiration level below the pump axis, the pipeline to be equipped with bottom valve;3, the pump should be checked before use, the motor blade rotation to be flexible, no jam, no abnormal sound, the fasteners should be tightened;4 、 check whether the motor rotation direction is consistent with the magnetic pump steering mark;
- Q: Why should the pump be closed when the centrifugal pump is started?
- On the other hand, the water on the pipe of the inlet pipe of the pump is stationary before the pump is opened, such as the sudden acceleration, and the water behind it can not keep up, which will cause the pressure of the inlet to drop suddenly and vaporize the water, and the centrifugal pump will be evacuated. (because of the centrifugal pump is rotating centrifugal force generated by the pump, leaf water and steam driven (gas) quality is very light, according to F= Ma, the centrifugal force is small, the pump can not be water sent).
- Q: 5 floor water pressure is too low, what kind of water pump is better?
- The location of the pump is too far away from the pumping pool, the suction of the pump is not enough, cavitation phenomenon, pumping water, this water pump manufacturers, the pump will be placed in a reasonable position
- Q: What is the name of the day pump and ground pump? Specific introduction
- People often say "day pump" actually refers to the boom pump, it also has many other name, such as pump, boom pump, concrete pump, concrete pump truck, these words are "day pump".Ground pump, in fact, refers to the pump drag pump. Therefore, to understand the difference between day pump and ground pump is to understand the difference between the boom pump and the tow pump
- 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
- The line between the fire pump buttons should be NHBVR-4*1.5 lines. 2 start, 2 answer. Some manufacturers reported that the 3 lines can also, this need to see which is the specific equipment. In addition, we need to introduce 2 warning buses.The above lines are individually distributed
- Q: What are the parts of a pump? How do you classify it?I just want to know
- Before opening the pump suction pipes and pumps must be filled with water. Open the pump, the impeller rotating speed, which leaves the liquid together with the rotation under the action of centrifugal force, the left outside impeller injection, injection of the liquid in the pump shell gradually slow the spread of indoor speed, the pressure gradually increased, and then from the pump outlet. The outflow discharge tube. At this time, in the leaves at the center of the vacuum area of low pressure liquid was thrown to the surrounding formation there is no air and no liquid, liquid pool at the surface of the liquid under the action of atmospheric pressure, through the suction pipe into the pump, the liquid is continuously pumped up from the liquid pool is also continuous outflow from the discharge pipe.Mainly by the impeller, pump shell, pump shaft, bearings and packing sealing devices and other components
- Q: Is vane pump good or gear pump good?
- 1) the reversible design of gear pumps can also usually reverse, but reverse after the suction port change, and the pump safety valve does not work; leaf pump is generally not allowed to reverse. 3) the single acting vane pump can be designed to change the eccentric distance by moving the stator at the constant speed, so as to achieve the purpose of variable direction.
- Q: Because the water pressure of the booster pump is not enough, it can not work automatically. It can only be operated by hand. It is inconvenient to use.
- The worst case is that the pump is not automatic when it leaves the factory, and no one can say whose product is 100%.But there may be automatic control of this piece, not debugging (this depends on the specific product manual or manufacturer)
- Q: What is the series of pumps? What is the difference between a unipolar and a multilevel? What is the meaning of each "first class"?
- Each impeller is of the first stage. (two impellers share only one level, and exit is only level one)
- Q: No negative pressure water supply equipment, both the main pump and auxiliary pump, power is not the same, how to choose the control cabinet?
- 1) microcomputer frequency conversion control cabinet2) water pump unit3) current stabilizing compensator4) vacuum suppressor5) all kinds of pipe fittings, valves and so on
