WZG type non negative pressure boosting stable flow water supply equipment

Overview of WZG type non negative pressure boosting and steady flow water supply equipment

The traditional water supply method relies on the water in the reservoir, which is usually supplied by the tap water network. In this way, the pressurized water enters the reservoir and becomes zero, causing a large amount of energy to be wasted.
WZG type non negative pressure boosting stable flow water supply equipmentIt is a complete set of water supply equipment developed by our professional technical personnel on the basis of pneumatic water supply equipment, which can be directly connected to the tap water pipe network and does not have any side effects on the tap water pipe networkHe replaced the water storage tank and roof water tank, which can fully utilize the pressure of the tap water network to directly or indirectly supply water, avoiding secondary waste of energy and secondary pollution of water quality, greatly saving infrastructure investment and shortening construction period.

The WZG type non negative pressure boosting and steady flow water supply equipment consists of an intelligent variable frequency control cabinet and a steady flow tankComposed of water pump units, instruments, valves and pipelines, bases, etc., it is suitable for all water supply systems that require increased water pressure and constant flow.

Characteristics of WZG type non negative pressure boosting and steady flow water supply equipment

WZG type non negative pressure boosting stable flow water supply equipment

Economic hygiene, significant energy-saving effects, and practical proof: the use of intelligent non negative pressure steady flow water supply equipmentThe cost of building a new water tank that can save energy by more than 50% can be reduced by 20% to 40% compared to other water supply equipment.
2. Easy installation and space saving:
The XWG type non negative pressure steady flow water supply equipment can be equipped with both horizontal and vertical steady flow tanks. Two types of steady flow tanks have different characteristics: horizontal steady flow tanks occupy less space, vertical steady flow tanks occupy less area, and steady flow tanksThe manufacturing and testing of the tank comply with the provisions of GB150 "Steel Pressure Vessels", and the inner wall of the tank adopts advanced "841 epoxy polyamide food container inner wall coating" for corrosion prevention, which is safe and meets national food hygiene standards.
3. Widely applicable and adaptable:
The XWG type non negative pressure steady flow water supply equipment can be used for domestic water supply, fire water supply, and can be equipped with any type of water pump. When the equipment is used for fire protection, it is recommended to equip it with a dedicated fire pump.
4. Fully functional and highly adaptable:
The XWG type non negative pressure steady flow water supply equipment adopts advanced human-machine variable frequency control technology, with soft start, overload, short circuit, overvoltage, undervoltage, phase loss, overheating, and stall protection functions. Signal alarm, self check, fault diagnosis, etc. are carried out in abnormal situations, and the water supply flow rate is automatically adjusted according to the high or low water consumption.
5. Advanced products and reliable quality:
The accessories used in the XWG type non negative pressure steady flow water supply equipment have been selected by many manufacturers and have reliable quality assurance. The key components in the product, such as motors, water pump bearings, frequency converters, circuit breakers, contactors, relays, etc., are made of international and domestic high-quality branded products.

Installation and commissioning of WZG type non negative pressure boosting and steady flow water supply equipment

1. The equipment foundation size should be constructed according to the foundation drawing provided by the manufacturer, and its position and standard should comply with the engineering design and the quality requirements for equipment foundation size and position in TJ231.
2. After the equipment is in place, level it with a spirit level, and its longitudinal and transverse levelness should be less than 0.1%.
3. After the equipment is installed and leveled, the foundation is grouted with expansion cement for a second time, and piping is carried out after 24 hours of maintenance.
4. After wiring the motor, the rotation direction should be confirmed to ensure consistency with the standard arrow.

Use and Operation of WZG Non negative Pressure Boosting Stable Flow Water Supply Equipment

1. Before using the equipment, the water pump rotor should be turned without friction or jamming.
2. The insulation of the motor detected by the 500V low-voltage shake meter should be above 0.5M.
3. The control instruments and circuits are undamaged.
4. Fully open the inlet valve of the water pump, close the outlet valve, open the exhaust valve of the pump one by one, and close the air valve after the liquid fills the pump chamber.
5. Place the switch in the manual position and jog the water pump with no load. The direction of operation should be consistent with the standard arrow.
6. Manually start and stop each water pump one by one, and check that there are no abnormal phenomena in the operation of the water pumps.

Maintenance and upkeep of WZG type non negative pressure boosting and steady flow water supply equipment

1. Before putting the equipment into operation, the system should be cleaned and purged to prevent impurities from entering the pump body and causing equipment damage.
2. The water pump should not operate for a long time with the outlet valve fully closed, nor should it operate at the hump in the performance curve, nor should it run without air. When the shaft seal adopts a disc root seal, a leakage of 10-20 drops/min is allowed.
3. The bearing temperature during operation shall not exceed 75 degrees Celsius.
4. The water pump should lubricate the bearings every 500 hours of operation.
5. Necessary measures should be taken for long-term shutdown of equipment to prevent contamination and corrosion. Anti freezing and insulation measures should be taken for winter shutdown.
6. The operation of equipment should be subject to preliminary discharge based on water quality conditions.

Functional characteristics of WZG type non negative pressure boosting and steady flow water supply equipment

1. Two working modes:
Automatic working mode: Automatic mode is a working mode under normal water supply conditions. Generally speaking, when the customer selects this method after normal water supply, all different water supply requirements of the pipeline network will be adapted to various functions under the effective control of the non negative pressure water supply equipment when working in automatic mode.
Manual working mode: This operation mode is set for emergency use by users in case of automatic working mode failure. This working mode completely adopts the simplest starting method, which directly starts and stops any water pump motor on the operation panel. Generally, it is only used in case of automatic failure or debugging.
2. Easy to integrate into intelligent management systems, the main components use high-quality components, and the entire system has high reliability and anti-interference ability. Its built-in standard serial communication port (RS485) makes communication between the system and the computer very convenient.
3. Water level protection function, when the water level in the water tank is lower than the set water level, the system automatically protects and shuts down. The liquid level controller has stable and reliable performance.
4. Automatic reset function, the system automatically starts when the power is restored after a power outage or when the water level is restored.
5. Fault pump shielding function, after the fault pump is shielded, it will directly exit the operating program and be replaced by a backup pump.
6. Automatic protection function: It has automatic protection functions such as overload, overcurrent, short circuit, phase loss, overvoltage, undervoltage, and water shortage shutdown.
