Traditional way of water depends on the water in the reservoir, generally
by tap water supply pipe network, in this way, the pressure of water into
the pool turned to zero, and cause a huge amount of energy wasted.
XWG no negative pressure steady flow water supply equipment, is our marina
fountain pump industry science and technology professional and technical
personnel in the pressure water supply equipment on the basis of the development
of a kind of can directly connect with tap water pipe network, and the tap water
pipe network does not produce any side effects of the complete water supply
equipment.He replaced the reservoir and the roof water tank, can make full use
of tap water pipe network pressure water supply, directly or indirectly to avoid the
secondary waste of energy and water quality of secondary pollution, greatly save
the infrastructure investment and shorten the construction period.
XWG no negative pressure steady flow water supply equipment by the intelligent
frequency conversion control cabinet, instrument, steady flow tank, pump, valve
and pipe, and applies to all need to increase the water pressure, constant flow of
water supply system.
Section 1, no pool, energy-saving building, information:
XWG no negative pressure steady flow water supply equipment economic health,
energy saving effect is remarkable, the practice proved: using intelligent have no
negative pressure steady flow water supply equipment to energy saving more than
50% of the cost of new pool, compared with other water supply equipment, can
save 20% ~ 40%.
2, simple installation, saving area:
XWG type without negative pressure steady flow water supply equipment can be
configured horizontal flow tank, also can configure vertical steady flow tank.Two
steady flow can have different characteristics: horizontal steady flow can occupy
the space is little, vertical steady flow tank occupied area is small, steady flow
tank manufacturing and testing are conform to GB150 "steel pressure vessel"
regulation, the tank wall is installed with advanced "841 epoxy polyamide feed"
container wall coating, anticorrosive, security accord with national food hygiene
3, versatility, and strong adaptability:
XWG type without negative pressure steady flow water supply equipment for the
drinking water, fire water, can be configured in any type of water pump, when the
equipment is used for fire protection, should be equipped with special fire pumps.
4, complete functions, high degree of computerized:
XWG type is negative pressure steady flow water supply equipment adopts the
advanced man-machine frequency conversion control technology, with a soft start,
overload, short circuit, overvoltage, undervoltage, lack of phase, overheating and
stalling protection function.In exceptional cases to alarm signals and self-checking,
fault diagnosis, etc, also according to the water height automatically adjust the water flow.
5, advanced products, reliable quality:
XWG type no negative pressure steady flow water supply equipment used in accessories,
after a number of manufacturers of screening, with reliable quality assurance, the key parts
of products, such as: motor, water pump bearings, inverter, breaker, contactor, relay,
adopted the international and domestic high-quality brand-name products.
Installation and commissioning:
1, the size of the equipment foundation shall be provided by the manufacturer of the
foundation drawing construction, its location and the standard should comply with the
engineering design and TJ231 "equipment foundation size and location of quality requirements".
2, equipment in place with level after leveling, the vertical and horizontal level should be
less than 0.1%.
3, equipment installation, after leveling with expansive cement was carried out on the basis
of secondary grouting and maintain piping of the reentry after 24 hours.
After 4, electrical wiring should confirm the direction of rotation, to ensure consistent with the standard arrow.
The use and operation:
1, before using the equipment should be set to move the pump rotor, no friction, card lag phenomenon.
2, 500 v low voltage motor insulation, shaking table test should be 0.5 M above.
3, control instrument, and no damage.
4, open the pump inlet valve, close the outlet valve, one by one to open the pump
exhaust valve, stay liquid filled with pump cavity after close the valve.
5, put the switch position manually, no-load point move water pump, the running
direction should be consistent with the standard arrow.
6, manually by rev. Stop the pump, check the pump running no abnormal phenomenon.
1, equipment before put into operation in the face of the system to clean up,
purging, lest cause equipment damage impurities into the pump body.
2, the pump should not be under the condition of the outlet valve full close long-term
operation, should not be in the performance curve of hump operation, more can't idle
running, when the shaft seals use packing seal allows for 10 ~ 20 drops/min leaks.
3, runtime bearing temperature is not higher than 75 degrees Celsius.
4, water pump running in every 500 hours when dealing with bearing on a refueling.
5, equipment, long-term service should take the necessary measures to prevent
equipment tarnish and corrosion, winter shutdown should use antifreeze, heat preservation measures.
6, equipment operation should be according to the condition of water quality for early discharge.
The feature of no negative pressure water supply equipment
1, two work modes:
Automatic working way: automatic way is a way of working as a normal water supply condition.
Generally speaking, when a customer after normal water supply, namely selected this way,
when he worked in automatic mode, all the different requirements of water supply pipe
network, will be in effective control of no negative pressure water supply equipment,
for a variety of functions to adapt to the work.
Manual work way: the operating mode is working for the automatic mode failure occurs,
emergency Settings for the user a way to work, the work completely using the easiest
way to get started, in this way directly to any one on the operation panel water pump
motor, generally only in the case of automatic failure or debug.
2, easily incorporated into the intelligent management system, the main parts adopt high
quality components, the system has high reliability and anti-interference, its own standard
serial communication port (RS485), causing the system and the computer communication
is very convenient.
3, water protection function, when the water tank water level is lower than the set water
level, the system automatically protect the downtime.Liquid level controller is stable and
Reply message after 4, automatic reset function, power outage or water recovery system
5, fault shielding pump function, fault shielding pump directly exit after operation procedures,
replaced by spare pump work.
6, automatic protection function: overload, over current, short circuit, lack of phase, overpressure,
undervoltage, and lack of water stop and other automatic protection function.
