Product Description:

Description

horizontal single stage fire pump is newly developed according to market needs.Its performance,technical conditions conform with international standard ISO2858 and requirements for national standard GB6245-2006《Performance requirements and test methods for fire pumps》.

Applications

It has been widely used in fire fighting and living water supply of industry the residence buildings.

Parameter range

Inlet diameter :50-200mm(2"-8")

Capacity:5-110L/s

Head:0.31-1.27MPa

Rate of rotation:2900r/min、1450r/min

Power:4-110kW

Two seal types: stuffing seal or mechanical seal

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:Piston filling and peristaltic pump filling which precision is high?
These two pumps are used as a metering pump to use, so the accuracy is to be on a par with the peristaltic pump has more advantages than the piston pump is the largest energy fluid conveying there are particles, and the piston pump is smaller than the peristaltic pump pulse, so we need to choose according to the material characteristics you need to transport.
Q:Suction stroke and lift of water pump
For example: there is a kind of water pump, the model is called "BSP" series, the volume is not large, but the nominal suction process can be 4 meters, it can not add water to 4 meters, it is considered to be relatively high in the micro pumpIn micro pumps, not all pumps have self-priming capacity ("suction stroke")Some centrifugal pumps there is no self-priming ability to use must first do add water. Although some micro pump with self absorption capacity, but "suction" are often the subject of "and the water inlet pipe in all air, can smoke the vertical height of water gap, even only half not so. The pump selection, the absorption process is a relatively important parameter.
Q:Must the water pump in the tank be all soaked in water?
Need a submersible pump in the water, but it is not entirely like this, I have to work for a long time no problem in water, but there is a problem you should pay attention to the water pump, at least in half, or stop when the smoke is not on water.
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
Q:What is the pump delivery? What's the difference between years and years?
Secondly, the landlord asked the question, although I did not go to the insurance company to practice the operation, but to my four years of learning, as well as internship experience, or can help you analyze, and I hope to help you.Pay is a one-time payment of premium -- all wholesale D sea n
Q:How about the depreciation of vacuum pumps?
(a) housing and buildings for 20 years;(two) aircraft, trains, ships, machinery, machinery and other production equipment for 10 years;
Q:Advantages and disadvantages of centrifugal pumps?
Centrifugal pump; advantages and disadvantages:(1) advantages:The structure of the pump is simple and compact, and the centrifugal pump has small area, light weight, little material consumption and high cost for the foundation. Therefore, the cost of manufacturing and installation is less.For high speed operation, the 2 pole or 4 pole motor can be directly connected. The drive structure is simple and easy to install.
Q:What are the differences between the sewage pump and the clean water pump?
The main difference between the sewage pump and the clean water pump is that:Impeller and runner design, as well as other parts of the configuration are very different.1., in order to prevent clogging of sewage pump, the main design of large flow channel, so naturally lead to relatively low efficiency, so the head is generally not high. Clear water pump flow smaller, smaller clearance, the head is relatively high.
Q:Difference between pump and compressor
A pump is a machine that transports liquids or pumps liquids. It transfers mechanical energy or other external energy of the prime mover to the liquid, increasing the energy of the liquid. The pump is mainly used to transport water, oil, acid and alkali liquid, emulsion, suspension emulsion and liquid metal, and also can transport liquid, gas mixture and liquid containing suspended solid. Pump can usually be divided into three types of displacement pumps, power pumps and other types of pumps according to the principle of operation. In addition to classification according to the working principle, it can be classified and named according to other methods. For example, according to the driving method can be divided into the electric pump and the turbine pump; according to the structure can be divided into single-stage pump and multistage pump; use can be divided into the boiler feed pump and the metering pump; according to the nature of transmission fluid can be divided into water pump, oil pump and mud pump etc.. In accordance with the non axial structure, can be divided into linear pumps and traditional pumps.
Q:What is the cause of the damage of pump bearings?
In high-speed equipment, the most likely damage to bearings is high temperature.
