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: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 vertical line NHKVV-7*1.5 is the remote starting line of fire controller to fire pump room.
- Q:The suction pump has a nominal suction range of 30 metersHow deep can a well be sucked?Well, sixteen meters,
- That is impossible. The suction height of the pump is caused by the centrifugal force of the vacuum. The water is sucked into the vacuum
- Q:Common failure treatment of piston pump
- x09x09 (3) no connecting key on pump shaft or motor shaft1) break2) missing x091) replace key2) patch keyx09x09 (4) pump internal slide vice stuck1) the clearance is too small2) parts accuracy is poor, assembly quality is poor, gear and shaft coaxial deviation is too large; plunger head clamping; blade perpendicularity difference; rotor pendulum difference is too big, rotor slot has wound or blade has scar, force after fracture and stuck
- Q:How to select metering pump head?
- The manufacturers of chemicals will give relevant recommendations, or consult the ProMinent chemical corrosion chart to determine the compatibility of the chemicals with the contact material.
- Q:Pump unloading in hydraulic transmission,
- Unloading is pumping oil directly back to the tank, the pressure is very low, energy saving
- Q:Why can the centrifugal pump hold down the pressure?
- Centrifugal pumps are vertical, horizontal, single-stage, multi-stage, single suction, double suction, self suction and other forms. Vertical centrifugal pump is referred to as submerged pump, molten salt pump and submerged pump. Centrifugal pumps use the impeller to rotate and cause centrifugal motion of the water to work.
- Q:Attention should be paid to the use of pumps?
- 1, pump shaft packing completely worn, it is necessary to add in time, if you continue to use the water pump will leak. The direct effect of this is the increased energy consumption of the motor, which will damage the impeller. 2, the use of pumps in the course of a strong vibration, then must stop to check the reasons, or the same will cause damage to the water pump. 3 gear pump valve Water Leakage, some will use the soil into the water pump inlet tube, the water washed in the end valve, this is indeed undesirable. Because when the dry soil into the inlet pipe, when the pump started working, these dry soil will enter the pump, which will damage the pump impeller and bearings, which shorten the service life of the pump. When the valve Water Leakage must take to repair, if it is serious that it is necessary to replace the new. 4 after the use of pumps must pay attention to maintenance, for example, when the pump is exhausted, we should put the water pump who put clean, it is best to remove the water pipe, and then rinse with water. 5 water pump on the tape should also be written down, and then always flush, and then light out to dry, do not put the tape in the dark damp place. Water pump tape must not be stained with oil, not to tape coated with some sticky things.
- Q:Rotary vacuum pump does not meet the requirements of vacuum, what are the reasons?
- (1) the disk, stator or bushing is worn and shall be inspected, trimmed or replaced with a rotary vane vacuum pump.(2) the pump temperature is too high, which not only reduces the viscosity of the oil, increases the saturated vapor pressure, but also may cause cracking of the pump oil. Ventilation, cooling and environmental temperature should be improved. If the exhaust gas temperature is too high, should be cooled before entering the pump, the environment temperature is high, should try to use a better high speed vacuum pump oil or 3# diffusion pump oil. (10) because of the deformation, wear or movement of the parts, the maximum opening height of the check head can be reduced or even unable to be opened, the intake of oil is too little, and the vacuum degree of the rotary vane vacuum pump is reduced, and should be adjusted as shown in the assembly section. Open high, more oil, but open too high, check valve in some places on the stop, it will not automatically drop, lost to prevent oil returns. The commonly used rotary vane vacuum pumps mainly include double stage rotary vane vacuum pump and single-stage rotary vane vacuum 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 working pressure of the hydraulic pump in the hydraulic transmission system?
- Generally speaking, for the fixed size, not limited equipment, the pressure can be selected lower, walking machinery heavy equipment pressure should be selected higher.If the load is selected, the working pressure is as follows:Load <5kN, working pressure <0.8~1MPa;Load 5~10kN, working pressure 1.5~2MPa;Load 10~20kN, working pressure 2.5~3MPa;Load 20~30kN, working pressure 3~4MPa;Load 30~50kN, working pressure 4~5MPa;Load 50kN, working pressure =5MPa;For example, the system work pressure of various machines is as follows:Grinder 0.8~2MPaModular machine tool 3~5MPaLongmen planer 2~8MPaBroaching machine 8~10MPa agricultural machinery, small construction machinery, construction machinery, hydraulic drilling machine 10~18MPa hydraulic machine, large and medium-sized excavators, heavy machinery, lifting transportation machinery 20~32MPa.
