Product overview
XBD series compared with previous fire pump, its with the pump outlet pressure differential between the reduced flow specification, minimum of only 0.05 MPa. The spectrum density increasing, the distribution is more reasonable, can better meet the needs of different floors and pipe resistance of fire control, meet the design selection. XBD series product is reached leading level, cover an area of an area small, light weight, low noise, good performance, the advantage of reliable running.
Application field
When the suitable operating mode
Flow range: 2.5 L, 200 L/S
Pressure range: 0.11-2.38 Mpa
Liquid temperature: 80 ℃ or less water
The working conditions
Low XBD series centrifugal fire pump can be divided into; Vertical single-stage, vertical multistage single export-oriented, horizontal multistage export-oriented, vertical multistage export-oriented, horizontal multistage export-oriented
Low XBD series centrifugal fire pump adopts copper alloy, copper alloy impeller pump shaft seal ring, stainless steel, ensure "at any time is up and running"
Low vertical/horizontal multi-stage export series satisfy the needs of high-rise building points to distinguish the pressure
Low horizontal multi-stage more export series intermediate exports may be two types of installation: vertical, horizontal direction
Low level at the end of the series vertical multistage exports more exports and export can be installed in four directions: middle inlet direction compared to 0, 90, 180 o, o o 270 o
Low horizontal multi-stage series is suitable for installation at a lower height of vertical space
- Q: What is a solution pump?
- Principle and structure features of canned motor pumpThe ordinary centrifugal pump is driven by coupling the pump impeller shaft is connected with the motor shaft, the impeller and the motor rotates while working and shielding pump is a kind of non seal pumps, pump and motor is sealed in a medium filled by pumping the pressure vessel, the pressure vessel only static seal and, by a group of wires to provide a rotating magnetic field and drive the rotor. This structure eliminated the traditional centrifugal pump with a rotary shaft sealing device, it can do no leakage.The pump and motor pump together, motor rotor and pump impeller fixed on the same shaft, use of shielding the rotor and the stator of the motor rotor separated in the medium, its power is transferred to the rotor through the stator magnetic field.
- Q: What is the name of the day pump and ground pump? Specific introduction
- Day pumpDay pump is called "day pump", the main reason is that it can deliver concrete to a certain height, make up for other concrete pump transportation shortage. Compared with other concrete pumps, the pump has its own boom, and the concrete can be transported without the use of artificial cloth. It is very convenient for use. At present, China's longest boom pump is 101 meters, which means that 101 meters under the floor can be completed with the help of day pump concrete delivery. In addition, the pump is equipped with a chassis, so compared with the ground pump, it can walk independently, moving very convenient, you can quickly move from one site to another location.
- Q: What are the advantages and disadvantages of the pump control system and valve control system in the hydraulic system? How to choose in the project?
- Pump control system is generally used for closed systems, the flow of the oil pump changes to control the motor or cylinder actuator action. The utility model has the advantages that the principle is simple, and the power of the engine can be fully utilized. The disadvantage is that the calorific value of larger, relatively poor precision.
- Q: Pump unloading in hydraulic transmission,
- Can be used for short-term shutdown, pump non-stopNo unloading, usually through the overflow valve back to the tank, high pressure, power, at this time insurable pressure, and so on
- Q: Advantages and disadvantages of centrifugal pumps?
- The centrifugal pump has no valve, so it is suitable for conveying suspended liquid, and the special design can also transport large solid suspensionThe pump can be made of chemical resistant material, which is suitable for conveying corrosive solution.The utility model has the advantages of simple structure, few parts, little failures, durability, low maintenance cost, convenient management and reliable work.The output can be adjusted even by the discharge valve fully closed, there is no danger of infinite rising pressure head.The liquid is transferred to a large quantity. And the pressure head does not require large, most suitable for centrifugal pump.
- Q: Brief description of centrifugal pump on / off operation
- First, the preparation before the start(1) carefully check the inlet and outlet pipe line, valve, flange and pressure gauge joint of the pump, whether the installation is safe, comply with the requirements, whether the flow is correct, whether the anchor bolt and other connecting parts are loose or not.(2) add lubricating oil to the bearing case, and the oil level is 2/3 of the gauge of the bearing box.
- Q: What is the function of a submersible pump?Do you have any knowledge about submersible pumps?.
- Important equipment for deep well water extraction. When in use, the whole unit dives into the water. The extraction of groundwater to the surface is water, mine rescue, industrial cooling, irrigation, water lifting, ship ballast, also can be used in fountain landscape, hot water submersible pump for hot spring bath, but also can be applied to the extraction of groundwater from wells, can also be used in rivers, reservoirs, canals and other water projects. The utility model is mainly used for farmland irrigation and water for human and livestock in mountain areas, and can also be used for central air conditioning cooling, heat pump units, cold pump units, cities, factories, railways, mines and site drainage. General flow can reach (10m3~650m3) per hour, head up to 1500 meters.
- Q: Why is the flow of the pump too small will occur cavitation phenomenon?
- Why is it easy to produce cavitation when the inlet flow of pump is lowered?This is because the main performance parameters such as the head, power and efficiency of the centrifugal pump are not fixed, but vary with the flow rate. The curve drawn on a coordinate paper is called the performance curve or characteristic curve of the centrifugal pump. What happens when the flow rate decreases? The disadvantage of throttling adjustment is that the pump flow is small, and the impeller is easy to cause cavitation
- Q: What is the cause of the damage of pump bearings?
- First of all, know your pump model, and what is the bad bearing, in order to accurately judge for you. Because in addition to some common reasons, the structure of different pumps, bearing damage caused by the reasons are different. Otherwise it is fraught with itching shoes.
- 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?
- Non negative pressure variable frequency water supply means no negative pressure superposed water supply equipment. When running, it is connected directly to the water supply pipe. Always test the pressure of tap water pipe network and water supply pipe network pressure control system, when the water pressure is lower than the pressure required by the user, the frequency conversion device based on water automatically control the pump speed through the steady flow compensator of water balance, maintain a constant pressure water supply. In the multi pump system, the control system can automatically dispatch the water pump according to the water consumption. It can balance the working time of the pump and ensure the pressure of the water supply. When the water supply pressure satisfy the required pressure, the system automatically stops the pump by the external water supply pipe network directly.
