WHWS Engineering Plastic Sewage Lift Pump
Flow range: 6-50m³ / h
Head range: 10-28m
Power range: 0.75-7.5KW
Temperature range: <80%
The WHWS (P) series sewage lifting equipment is a high-efficiency and energy-saving integrated underground sewage solution that specializes in treating sewage that cannot be discharged to municipal sewage pipes by its own gravity. Widely used in high-end villas, subway stations, civil buildings, large industrial and mining sewage can not rely on the gravity of sewage itself. This product has a high degree of intelligence, a small footprint, a closed box structure without odor emission, easy installation and use, and other features are widely welcomed by customers. Our company designs WHWP stainless steel sewage lifting equipment and WHWS engineering plastic sewage lifting equipment respectively according to customer needs.
Conditions of Use:
· Using PLC (programmable controller) control technology
1. Greatly enhance and improve the stability and reliability of control system and equipment operation, and fully realize unmanned operation;
2, to achieve dual pump alternate operation, low-level pump stop, high-level start water pump and other functions, can also be pump failure, phase failure and phase sequence error protection, operation failure and other alarms;
Intelligent repair of faults and multi-point alarm indication
1. When there is an abnormal situation such as an abnormal amount of sewage in the basement, a large debris clogging the main road, an accumulation of water in the equipment pit, and a phase error of the power source, the control system can detect and identify the abnormal situation, and automatically repair the operating status. Automatic alarm indication after self-repair.
2.Single pump automatic running state-single pump failure automatic switch
When the pump fails, the program will automatically transfer the equipment to the "single pump automatic operation state"; when the pump is repaired and the thermal protection is reset, the system will automatically restore the "dual pump automatic alternate operation" state;
3. When there is an abnormal situation such as stagnant water or missing phase and phase error in the water trap of the local lower equipment, the control system can detect and identify, and switch to the abnormal situation and automatically alarm indication;
4.The equipment can realize automatic and manual control conversion on site
The device can be equipped with a stainless steel electronic liquid level sensor. The liquid level sensor is equipped with two pumps, “Liquid pumping level” and “Liquid pumping level”. Stainless steel electronic liquid level sensor can be configured. It has the advantages of corrosion resistance, reliable operation, high sensitivity, long life, simple installation, and easy to wear and corrosion . Through the induction feedback signals of the electrodes, the two water pumps are accurately controlled to run alternately, which avoids the occurrence of sewage overflow due to control errors caused by entanglement and shielding.
Implement remote monitoring operations
The BAS data cable can be used to transmit various signals of the equipment operating status required by the user to the monitoring room, so that the duty staff can intuitively understand and operate the equipment operating status on the monitoring screen without leaving home; users can also pass the equipment operating status through the Internet Synchronized display on the computer in the general control room enables the after-sales service personnel to accurately determine various abnormal conditions, guide users to maintain in a timely manner, and provide users with comprehensive technical support and services, which greatly reduces the cost of equipment management.
Structural characteristics and working principle:
Domestic sewage discharge of high-rise living buildings with basement;
Wastewater discharge from commercial service places such as underground shopping malls, restaurants, and bathrooms;
Sewage discharge from subways, underground crossings, etc .;
Sewage discharge from civil air defense works;
Pump body cast iron
Water inlet pipe
Sewage check valve
辅泵: Auxiliary pump:
When water seepage is likely to occur in the environment where the sewage lifting equipment is located, it is recommended that customers add auxiliary pumps next to the sewage lifting equipment to protect the safety of the equipment.
2.Auxiliary pump selection
Head of auxiliary pump should be consistent with head of main pump
When Q master <15m³ / h, Q auxiliary = Q master
When Q main ≥15m³ / h, 10m³ / h≤Q auxiliary ≤20m³ / h
You can also choose according to the actual situation of the user.
Note: The auxiliary pump equipment is equipped with a special control cabinet for sewage lifting equipment.
