Structural Characteristics
XBD-I series horizontal single stage fire pump set is mainly made up of 1.pump cover 2.impeller 3.shaft 4.seal ring 5.packing ring 10.Suspension bearing parts 12 .etc.
Pump casing and pump cover of XBD-I series horizontal single stage pump are split from back of impeller,namely,back-open structure.It is convenient to maintain,when maintaining,pump casing,suction pipe,discharge pipe shall not be dismantled,so rotor parts can be taken out for maintenance easily.
Pump casing(namely,pump body and pump cover) composes pump working room.Impeller,shaft and rolling bearing are rotors of pump.Suspension bearing parts support the rotor parts,and rolling bearing bears the radial force and residual axial force of pump.
To balance the axial force of pump,there are seal rings on the front shroud and back shroud of impeller,and there is balancing hole on the impeller back shroud.Some of the pumps do not have too much axial force,so there are no seal ring or balancing hole on the impeller back shroud.
Pump seal is made up of packing gland 9,shaft sleeve 8 and packing 11,or mechanical seal is applied to avoid air getting inside or too much water leakage.
There is a shaft sleeve through the packing cavity to avoid shaft abrasion.There is o-ring between shaft sleeve and shaft to avoid the air getting inside or water leakage.
Driving way of pump is connected through coupling and motor.Pump rotates clockwise from the direction of drive.
- Q: Know flow and lift how to calculate the pump power?
- N=Q.H.g. P / nN - motor power, kWH - pump head, MQ - pump flow, m^3/sG - gravity acceleration g=9.81
- Q: Troubleshooting of diaphragm pump
- In the application of the pump, these conditions are likely to encounter. Each situation can be divided into several possible reasons. This guide lists the causes of failures and gives appropriate corrective maintenance measures. The meaning of all the specific terms in the guide is listed later.Air valves - copper or stainless steel valves are bolted to the center of the pump by four bolts.The piston aluminum cylinder is enclosed in the air valve to control the gas flow.Cavitation - because the pump inlet for the amount of fluid to reduce or lack, the pump discharge is less than the amount of quantitative. In fact, the fluid chamber is full of fluid before it is discharged.Static pressure drop - the inlet pressure from the pump centerline to the free point - the inlet is measured in pounds, including the specific gravity and velocity of the fluid.
- Q: The distance from the pump button to the ground
- After confirming that the fire pump has started running, issue a command signal to the hydrant button to light the green answer light.
- 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: Why can the centrifugal pump hold down the pressure?
- The pump before starting to pump shell and the water pipe filled with water, and then start the motor, the pump shaft to drive the impeller and water do high-speed rotation, centrifugal water movement, was thrown to the outer edge of the impeller, the pressure water pipeline flow through the volute pump into the pump shell.
- Q: I live on the 8 floor. Often there is no water. Life is very inconvenient. What kind of pump do I have to install? What should I pay attention to when I buy it? What's the pump for that brand? Should it be installed in that position?
- (8) check the suitability of the foundation and whether the size of the foundation corresponds to the size of the pump.(9) find the position of positive pump and motor, pump set and anchor bolt and the inlet and outlet flanges, to ensure that the flange torque of the pump conforms to the standard. Check the inlet and outlet piping before alignment. Make sure the weight of the inlet and outlet pipe does not exert force or torque on the pump. When looking for, should also pay attention to eliminate the pump rotor movement, so as to avoid the end gap error. If checked after the pump is working, it should be carried out under cold condition. It is important to draw attention to the fact that the pump set of the complete set of factory is only rough looking (checked with a ruler) when it is shipped. It may cause displacement when it is transported.
- Q: What are the characteristics of a vertical multistage centrifugal pump?
- Vertical multistage centrifugal pump system using the latest international advanced IS type hydraulic model based design for high efficiency centrifugal pump with multi segment, the soft packing or mechanical seal, has the characteristics of high efficiency, large flow, high lift, no leakage, a wide range of performance, safe operation, stable operation and long service life and small area.
- Q: What's the word "pump"? Is that what advocates mean?RT
- Is generally believed that the "wholesale" is the "hoarding" of "hoarding" variant, can be used to replace the word "store". And "wholesale" compared to "store" is clearly better and better recognize, because the "store" is a phonogram, hoard shaped characters "mouth", said the biggest the range of aggregation, like a grain bin; "Tun" is also phonetic, semantic. Tun, originally refers to the grass speared out of shape, with curly tails, and gathered the meaning.In this case, the "fans" can be written as "Yong Tun". But this is also troublesome, because the "store" in addition to read "Tun" (Ping Sheng), another pronunciation of "Dun" (Qu Sheng), who said food utensils, when we had the "Valley" store. So, if the "fans" to "hold", is also wrong. "Bin Zhao Wei fans" although it sounds strange, but at least not ambiguous; if changed to "Zhao Wei", is that we have to hoard may hear "Zhao Wei" or "Zhao Wei hold hip", hold the shield this is not the more the more chaotic change it!It is suggested that the "fans" to "fantastic", the modified method was acceptable. In modern Chinese, "public" does not necessarily mean that many, can also refer to a single. "One of the masses", "one of the audience (or audience)" this kind of argument, has been about good. Since this kind, we say "a fantastic" what not? "Fantastic" at least than the "fans" straightaway. The problem is, the word and Hong Kong Standards, there is no "fantastic".
- 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: How to calculate the motor power of metering pump?
- The total mechanical power and hydraulic power, divided by the overall efficiency of pump, and the pump head and the utilization rate of pump mechanical efficiency, and then multiplied by 1.1 times (API675), you can get a metering pump motor need more power.
