Applications
It has been widely used in fire fighting and living water supply of industry the residence buildings.
Parameter range
Inlet diameter：150-300mm(6"-12")
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:Troubleshooting of diaphragm pump
- The troubleshooting guide for diaphragm pumps, when encountered in one or more of the following situations, this information can be used as a guide to help you develop maintenance measures.As shown below, some of the abnormal operating conditions described in this guide are: A) fast circulation / low flow B) no cycle / slow cycle / irregular cycle C) leakage D) noise E) component rupture
- Q:If the suction pump does not have enough suction range, you need to add a vacuum pump to increase the suction stroke. How do you install the suction pipe of the vacuum pump? Water pump impeller is not closed, it is normal that the vacuum pump is unable to pump suction pipe to a vacuum, is it because the water pump outlet pipe connected to the role of the check valve? But the water pump, outlet pipe, check valve sealing performance can achieve the function of non leakage?
- Vacuum suction principle of self suction pump:Assuming that the pump connected with the water inlet of a sealed container, the container has plenty of water, since the start of a water pump, water is thrown out of the water impeller pump body, water inlet seal vessel due to the extraction of water to form a vacuum cavity, this assumption will be connected to vacuum cavity and exposed to atmospheric conditions of water, water at atmospheric pressure under the effect of entry into the vacuum chamber".
- Q:Common failure treatment of piston pump
- 1) overflow valve regulation is too high, overload after the pump2) the overflow valve spool is blocked, the central hole of the valve core is blocked or the overflow valve is blocked by a damping hole, and the overflow is not overflow3) pump outlet one-way valve installed or spool blocked and stuffy pump4) motor fault x091) adjust the relief valve pressure value2) repair valve boring3) overhaul check valve4) overhaul or replace the motor
- 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
- According to the water quantity form fire flow water supply system fire safety in high-rise building fire hydrant pump lift is 10L/s, accurate algorithm is to say after a simple calculation with each indoor hydrant flow is two 5L/s bolt so to get the most unfavorable point for the calculation unit to calculate the minimum requirements, with the most unfavorable point suppository pressure specifications 0.07MPa, partial loss of the most unfavorable line and the line (according to the equivalent length) and loss (according to the material resistance coefficient), and finally the pump head loss of gravity difference. But we just calculate the construction elevation difference multiplied by 110% to 120% to determine the head {there is a need to know is: conversion head (m), (kg) and MPa kg 1MPa=10 kg = 100m is the vertical water column on unit area pressure conversion
- 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:How many pumps does the 80cm tank use?
- Filter pump to select the water per hour can be filtered more than 3 times, I personally feel that this is almost enough. Of course, the more times the better, but also consider that if the pump is too large, the water inside the tank will be too large.128X3=384LThat is, the flow must be more than 384L/H of the water pump.You can buy a bigger pump, because the pump for a long time there will be some attenuation and domestic things in general to sign data, so it should be based on your actual situation to buy. Taobao on this category is about 20~40 yuan.
- Q:Hydraulic pump displacement refers to the pump shaft what?
- Displacement of the hydraulic pump refers to the axis of each turn, the volume discharged, called displacement, the unit is ml (ML),
- Q:Rotary vacuum pump does not meet the requirements of vacuum, what are the reasons?
- 1) oil rotary vane vacuum pump is too low, no effect on the oil seal exhaust valve, rotary plug to refuel after large exhaust sound, and oil mist, that the level is too low, the gas can be eliminated.(2) the vacuum caused by the condensable steam pollution of oil should be changed, and new vacuum pump oil should be replaced.
- Q:What is the difference between centrifugal pump and rotary vane pump? What are the distinctive characteristics or principles of rotary and centrifugal? O (a _ U) O thank you!
- Directly said vane pump on the line, generally do not say rotary vane pump.The centrifugal pump is divided according to the direction of the liquid flow in the impeller
- Q:Why does the centrifugal pump start with a closed valve and the axial pump starts with an opening valve?
- Centrifugal pumps require a vacuum to produce negative pressure, which allows atmospheric pressure to lift the water surfaceAxial flow pump impeller is thrust on water
