Non negative pressure variable frequency water supply equipment, dual-mode variable frequency water supply equipment, variable frequency voltage stabilizing water supply equipment

Description :

Non negative pressure variable frequency water supply equipmentAdvantages:

　　1. By utilizing the speed regulation function of the frequency converter, the speed of the water pump is automatically adjusted. When the water consumption changes (water pressure changes), the water pressure is automatically adjusted and kept constant.

　　2. If the water source is insufficient, the variable frequency constant pressure water supply device will activate protection and stop the water pump. Its characteristic is constant pressure, which means that no matter how the water consumption changes, as long as it is within the adjustment range, the water pressure can be guaranteed to be constant, that is, controlled at a point.

　　3. It has the advantages of energy saving, high degree of automation, constant pressure, and small size.

　　dual modeVariable frequency water supply equipmentCharacteristics of

　　1. High safety, the device adopts dual-mode water supply, automatically detects the water pressure of the pipeline network, and intelligently switches. When the water pressure is sufficient, the municipal pipeline network is used for stacked water supply. When the water pressure is insufficient, the water tank is filled with water for replenishment, fully utilizing the protection of the municipal pipeline network and ensuring high water supply safety.

　　2. High degree of intelligence, the system automatically detects water pressure and intelligently switches, truly realizing remote monitoring function.

　　3. Good energy-saving effect, (1) using Yufu Italy's imported silent submersible pump and submersible motor, the efficiency of the pump and motor is higher than traditional products, so the equipment has high operating efficiency;

Non negative pressure variable frequency water supply equipmentMaintenance and upkeep:

　　1. Check the impeller and remove foreign objects. In case of special circumstances where the water pump impeller is damaged or foreign objects are rolled in, it is necessary to inspect and clean it. The bearing body and tail cover need to be removed, and the shaft and impeller need to be pulled out to the back. The pump body and inlet and outlet connections do not need to be removed.

　　2. Check the stuffing box: When using a stuffing box seal for variable frequency water supply equipment, attention must be paid to the tightness of the stuffing box. If it is too loose and leaks too much, it will affect the performance. Under normal circumstances, the leakage rate should be around 60 drops per minute. Dripping water is normal, but splashing water around is abnormal. Recommended reading: Disposal path for damaged valves in variable frequency water supply equipment

　　3. Lubricated bearings: The variable frequency water supply equipment adopts imported SKF series semi enclosed bearings, which have been lubricated with high-temperature grease before leaving the factory. They can operate continuously for 2 years and need to be lubricated once a year thereafter.

　　4. Check mechanical seal: When using a mechanical seal for variable frequency water supply equipment, it is important to avoid running it without water supply. During debugging, only momentary tapping is allowed. During normal operation, a small amount of water may drip out from the front of the water blocking ring. When there is a large amount of water leakage, the friction ring should be checked, repaired or replaced. The normal service life of the mechanical seal is 8000 hours, and it is generally not necessary to replace the entire set. Only the pair of friction rings, the dynamic ring and the static ring, should be replaced.
