Non negative pressure variable frequency water supply equipment manufacturer Non negative pressure variable frequency water supply production

Description :

Non negative pressure variable frequency water supply equipmentIt mainly consists of a frequency conversion control cabinet, pressure sensors, water pumps, etc. The frequency conversion control cabinet consists of circuit breakers, frequency converters, contactors, intermediate relays, PLCs, etc. (1) The capacity of the reservoir should be greater than the hourly water supply. (2) The head of the water pump should be greater than the actual water supply height. (3) The total flow rate of the water pump should be greater than the actual water supply. (4) Selection of frequency conversion control cabinet: Users can determine the model and number of water pumps based on the water supply volume and height, and then select the control cabinet. Main technical data: Control connection: 2 programmable analog inputs (AI); 1 programmable analog output (AO); 5 programmable digital inputs (DI); Two programmable digital outputs (DO). Continuous load capacity: 150% In, allowing 1 minute of serial communication every 10 minutes. Standard RS-485 interface allows the frequency converter to be easily connected to a computer. Protection features: overcurrent protection I2t、 Overvoltage protection, undervoltage protection, overheating protection, short circuit protection, grounding protection, undervoltage buffering, motor undervoltage/overload protection, locked rotor protection, serial communication fault protection, AI signal loss protection, etc. Compact appearance and easy installation. The product has been certified according to various electrical safety standards and complies with GE, UL, and quality certification systems such as ISO9001 and ISO4001. The ACS600 frequency converter is equipped with eight application macros, including PID, PFC, and pre flux. Simply select the desired application macro, and all corresponding parameters will be automatically set. The input and output terminals will also be automatically configured.

　　Product features of non negative pressure variable frequency water supply equipment: 1. Cost saving: Save about 50% of investment, no need to build reservoirs or roof water tanks, adopt stacked water supply, and reduce initial equipment investment. 2. Efficient and energy-saving, with low operating costs: It can fully utilize the water supply pressure of the municipal pipeline network, adjust the difference and supplement, without generating negative pressure, and can save 30% -90% energy compared to traditional water supply equipment. Power outages can also maintain the water pressure and supply of the municipal pipeline network. 3. High degree of intelligence, simple operation, and labor-saving: The device is controlled by a fully automatic intelligent controller, which adjusts itself according to the user's water consumption and the tap water pressure of the pipeline network, and is unmanned. And it adopts a human-machine interface (text, numbers) display, allowing customers to more intuitively see the operation status of the equipment. 4. Environmental hygiene: The equipment operates in a fully enclosed manner, completely eliminating secondary pollution of the water source. 5. Complete protection functions: It has perfect automatic protection functions for overload, short circuit, overvoltage, undervoltage, phase loss, overcurrent, short circuit, water source shortage, etc. Can perform signal alarm, self check, fault diagnosis, etc. in abnormal situations. 6. Small footprint and easy installation: The entire equipment consists of only one set of water supply control cabinet, non negative pressure stabilizing tank, and water pump unit, making installation very simple and convenient. 7. Extend the service life of the equipment: It can reliably achieve soft start for multiple pump units, avoiding impact on the power grid and pipeline network, and rotating them alternately, greatly extending the service life of the water pump and motor. The lifespan of the equipment can be extended by more than three times.
