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:What is a water pump coupling device?
- Advantages of water pump coupling device:1. automatic coupling device, easy installation and maintenance. In the absence of automatic coupling device, fixed installation, such as water pump failure, maintenance personnel need to unscrew screws, lifting pumps for maintenance, or with other small pumps pumping water perfect maintenance,If the water is dirty, it is difficult for people to get down, when the inspection and repair encountered great difficulties. But it is equipped with GAK submersible sewage pumpAfter the automatic coupling device needs lifting, the person can directly lift the water pump without the need to screw the screw into the waterAfter graduation, down the guide rail, you can realize the sealing of water pump and pipeline, so as to make the pump run normally. Small sewage pumps are freeInstallation, large sewage pumps are generally equipped with automatic coupling device, automatic installation, installation and maintenance is very convenient.
- Q:What should be used to pay attention to the use of mechanical pumps?
- There are many kinds of pumps, such as centrifugal pumps, piston pumps, diaphragm pumps, vane pumps, gear pumps, etc.
- Q:Water pump spoon pipe for power plantWhich hero can tell me what is the water pump spoon tube ah? And its role
- The spoon pipe is not a feed pump, but also is an adjusting oil inlet device of a hydraulic coupler matched with a feed pump
- Q:Is the centrifugal pump large or small?
- When the liquid is lowered at a certain temperature to the vapor pressure at this temperature, the liquid bubbles. The phenomenon of producing bubbles is called cavitation. When the bubbles are flowing to the high pressure, the volume of the bubbles is reduced so that they are destroyed. This due to the pressure of rising bubbles disappear in the liquid in the phenomenon called cavitation bubble collapse. The local pump is in operation if the over-current part (usually the impeller blade inlet somewhere later) for some reason, the absolute pressure of pumping the liquid was reduced to liquid vapor pressure temperature, liquid vaporization began there, produce a lot of steam bubble formation, when the liquid contains a lot of bubbles by forward high pressure impeller Zone, high pressure liquid around the bubbles in the bubble decreases drastically and rupture. Condensation in the bubble burst and the liquid particle at high speed to fill a hole in this moment has a very strong effect of water hammer and the impact of high frequency against the metal surface, the impact stress of hundreds to thousands of atmospheric pressure, impact frequency can be up to tens of thousands of times per second, serious breakdown when the wall thickness will be. The process of cavitation in a pump is caused by the bursting of bubbles and bubbles in the water pump and the destruction of the over-current components. Water pump cavitation, in addition to the over-current components will have a destructive effect, but also produce noise and vibration, and lead to the performance of the pump down, seriously when the pump will be interrupted liquid, can not work properly.
- Q:Does the reservoir water heater press the booster pump (high marks)?
- If insufficient pressure really, adding an automatic booster pump in the water inlet, is feasible. Home booster pump, a basic model, to sell the place to ask the next to know, generally 200 yuan or so, traffic 0.3-1.8, 90~150 watts on it. Do not buy too large, too much power, the water will also be too large, but the water heater will not be used.
- Q:A residential building with a floor height of 11 stories and a roof height of 33 meters. The height of the water tank is 37.7 meters. The basement is -3.3 meters, only set fire hydrant, fire pump only consider the indoor fire water, fire flow should be 10l/s. Now select a fire pump, concrete should be much traffic, big head, flow determine how? How to determine the head, I hope to say some more detailed, thank you, and there is to explain this question, why is the fire pump lift 120?. Thank you
- Modify the part: (the design of regional common fire pump should be in accordance with the requirements of the original design, building design) contains a 55m high building, and the basement is about 6m, the pump reached in the basement height about 61m (common fire pump should be based on the highest floor of other low floor area, low ring and take in this case, relief measures) 61 levels, the most unfavorable hydrant to reach 0.07MPa (maximum allowable 0.5MPa) plus loss of lift at least about 90m more appropriate, of course can be higher to take relief measures (120 too high), the basic flow of lossless (with the same time there is only one building fire) according to the maximum amount of a building fire water pump set can be, there must be a backup with a preparation, and then select the appropriate pump manufacturer specification query.(the 20 houses on 99m are only shared with a 135m pump)
- Q:There are second cutting, third cutting, why three times?
- There are 2 situations, first, for example, a XXXX-160 type pump head 32, flow 100, motor 15kW, according to the model we need to cut a become head 28, flow rate of 88, this time, in addition to cutting the impeller, the pump or the original pump motor, became 11kW this is, re designed a new model, namely XXXX-160A, but most structural components did not change. In the same way, we want to design a XXXX-160B that makes the head 24 and the flow rate 80, then we just need to cut the impeller again and match the smaller (7.5kW) motor (the motor bracket needs to be redesigned). In general, multiple cutting impellers are designed to expand and enrich the model. Second, the actual use, if you think the flow head is too large, but also can be cut to make it smaller to adapt to practical applications. But the 2 and 3 cuts you ask are the first.
- Q:Do you have a suction pump higher than 9 meters?
- Pump rated suction generally 7 meters or so, it is estimated that no one calibration pump suction stroke 9 meters. Calibration suction range of 9 meters is not reliable.
- Q:What are the ways of hydraulic pumps?
- Hydraulic pump is a power component of hydraulic system. It is driven by an engine or an electric motor. It draws oil from the hydraulic tank to form a component of the pressure oil which is sent to the actuating element.
- Q:How to maintain and repair the booster pump of pipeline pump?
- Installation and use1. use rubber washer and bolt to connect the pump flange at both ends and the pipe flange. In order to use and maintenance convenience, in the pump inlet and outlet pipelines should be installed with a regulating valve.2. open the inlet control valve, so that water into the pump, in order to keep the cavity filled with liquid (otherwise it will damage the seal), close the outlet valve.3. turn on the power and make sure the correct turn.4. make sure the pump starts and runs after turning.5. adjust the opening of the outlet valve so that the pump runs near the design point, depending on the rated flow and lift of the pump. [for this reason, it is better to place a pressure gauge near the outlet flange). Note: this pump is strictly prohibited to run without water, so as not to damage the seal.
