Product Overview
XBC Series Diesel Fire Pump Company in strict accordance with the
national standard GB6245-98 "fire pump performance requirements and
test methods" and the United States Fire Protection Association
Standard NEPA20 "centrifugal fire pump installation" and other
standards developed a new type of fire-fighting equipment
(hereinafter referred to as equipment), the series is equipped with
the device according to the fire pump (single-stage single-suction,
single stage double suction, multi-stage segments) can be divided
into XBC-IS, XBC-SLOW, XBC-D three sub- series, equipment pressure,
flow range, the application required to meet the fire almost all
occasions.
Equipment with diesel engines are high-quality products using
domestic or imported, with the launch characteristics of a good,
strong overload capacity, compact structure, easy maintenance, easy
to use, high degree of automation, is an advanced, reliable
fire-fighting equipment.
Equipment, normal operating conditions:
Altitude ≤ 1000m; Ambient temperature: +5 °C ~ +40 °C;
Relative humidity: ≤ 90%.
Structural features and function:
Equipment from the X6135, 12V135, 4102,6102 series diesel-powered,
diesel engine (available with clutch) through high-elastic coupling
and fire pump connected to form the fire pump, the unit also
included the diesel tank, radiator, fan, controlscreen (automatic
units available) and other components.
When the automatic control unit, the diesel engine automatically
controlled by the split counter (programmable) to achieve the
automatic system in a first degree, inputs, auto-switching (switch
to the diesel engine pumps electric pumps or diesel pumps to switch
to another group a diesel pump), automatic protection (engine
speed, oil pressure, high hydrological, three failed to start, low
oil level, low battery voltage alarm shutdown protection) and other
functions, users can also fire with automatic fire alarm center or
interface for remote monitoring.
To ensure the unit in less than 5 °C environment to work, the unit
can be attached to the cooling water pre-heating device AC220V.
General Data
Diesel engine with electric fire pump pop group, composed of
automatic fire regulator pump water supply system. Course of their
work, see "Engine Control System" introduced. Equipment can be
achieved together with the fire control center.
System structure and principle
1. LED-BZ (H) series diesel engine pump set control
General Data
Automatic fire protection water supply systems are usually
regulated by the pump, electric pump (main pump), automatic diesel
pump (pump equipment), working principle is: the usual pressure in
the pipe in P1 (low) ~ P2 (high pressure), lower than P1 regulator
starts the pump, the pump stops the pressure rose to P2, because P2
slowly leaking pipe down to P1, regulator pump then start, and so
forth to maintain the pressure at P1 ~ P2, and when the water
surge, pump regulator can notdecreased rapidly to maintain P1 P3,
electric pump starter, pressure rose to Pw and meet the fire water.
Such as power failure or faulty electric pump, pressure continued
to decline from the P3 to P4 will automatically start the diesel
pump, the pressure rose to Pw and water supply, electric or diesel
pump pump pump shall be stopped manually after stopping the pump
manually to determine, frequently.
(1) LEC-BH series of semi-automatic fire pump diesel engine control
device
This type of cabinet (box) with manual, semi-automatic control
functions, with the engine oil pressure, water temperature display;
with the battery charging current display; tank oil level alarm;
state electric fire pump failure or power outages, it can
automatically start the engine pump; to remote start diesel pump.
This control method is generally used in diesel engine power less
than 110kw of occasions.
(2) LEC-BZ Series automatic fire pump diesel engine control device
This type of cabinet (box) with manual, automatic control, with the
engine oil pressure, oil temperature, water temperature display and
alarm function abnormalities, with the battery charging current
display; tank oil level alarm; automatically (can be remotely )
start and stop diesel pumps; ultra-high speed, low-speed stop
alarm; three starter failure alarm; automatically charge the
battery voltage is low; and automatic fire and the fire alarm
center or excuse, remote linkage control, such as the system for
multi-pump unit, can achieve the unit to switch between the regular
inspection and fire pumps, power frequency voltage function
2. LEC-DZ (H) series diesel generator control equipment
The control principle similar to the diesel generator diesel engine
pump configuration control, mainly used in civil construction in
the self-generator voltage of 230V/400V emergency diesel generator
sets, engine blocks should always bring their own emergency
preparations start in the state, operating power, thermal systems,
fuel oil, lubricating oil, cooling water, and indoor temperature
and indoor environment should be to ensure the unit can start at
any time conditions, when the electricity is interrupted, the unit
should start immediately, and can be invested in the 15s normal
load operation. Unit should be in power system chain, when the
electricity is restored, the unit should be delayed switch to
electricity supply, and idling stop automatically after 3 ~ 5min.
