Welcome to choose Shanghai Longya variable frequency water supply equipment and non-negative pressure water supply equipment series products. . All colleagues in our company would like to express our deep gratitude for your visit! 1. Introduction: With the development of variable frequency speed regulation technology and people's continuous improvement in the quality of drinking water, variable frequency water supply equipment has been widely used in multi-story residential communities and domestic fire water supply systems in high-rise buildings. Frequency variable speed water supply equipment generally has the characteristics of low equipment investment, stable and reliable system operation, small footprint, energy saving and water saving, high degree of automation, and convenient operation and control. However, in actual applications, if the selection and control are improper, not only will the energy saving purpose not be achieved, but electricity will be wasted. The following is an introduction to the application and control methods of variable frequency water supply equipment based on our many years of practical experience, for users' reference when designing, transforming, and selecting models. 2. Introduction to Shanghai Titanium variable frequency water supply equipment, non-negative pressure water supply equipment and variable frequency constant pressure water supply equipment. This type of equipment is widely used in practical applications. The system consists of a water pump unit, a circulating soft-start frequency conversion cabinet, a line programming controller, a pressure sensor, Piping system, etc. The frequency conversion cabinet is composed of frequency conversion speed regulator and low-voltage electrical appliances. The system generally selects water pumps of the same model. Taking the Taiwan pump as an example, the working situation of the system is as follows. Normally, the Taiwan pump supplies water with variable frequency. When the water supply of the Taiwan pump is insufficient, the first pump will run at power frequency, and the frequency conversion cabinet will soft-start the third pump. pump, if the flow rate is not enough, the first pump will run at power frequency, and the frequency conversion cabinet will soft-start the third pump. If the water consumption decreases, stop the power frequency pump in sequence according to the sequence of starting the pump, until the last pump supplies water with variable frequency and constant pressure. In addition, the system has a regular pump replacement function. If a certain pump continuously runs beyond the frequency conversion cabinet, it can automatically stop the pump and switch to the next pump to continue the frequency conversion operation. The pump replacement time is set by the program and can be adjusted at any time as required. This balances the running time of each pump and extends the life of the overall pump unit. This system is generally suitable for larger-scale multi-story residential areas (such as households or above) or other large-scale water systems, and the water pump power is generally not exceeded. In addition, it is also suitable for other occasions where small flow of water is used for a short time or water consumption does not change much, such as circulating water systems. Product description, manufacturer capabilities, performance and advantages, product packaging, product use, three equipment features, LCD Chinese character display, parameter display and settings are clear at a glance, and automatic fault alarms are available. Adopting the fuzzy control principle, there is no need to adjust controller parameters during automatic optimization. It has fast response, high precision, and small impact on the pipe network when switching pumps. It has automatic timed exchange settings for water pumps to increase the average service life of the water pump. It has an automatic fault reset mechanism and an adjustable delay. , after the frequency converter fails, you can choose to automatically switch to power frequency operation (pressure interval control). Each main pump can be set to cycle soft start or direct start, with flexible configuration and programmable output. The power output point is a relay, which can be connected to AC and DC loads (can be connected to a buck or soft starter). The operation control signal of the frequency converter is the relay switching value. When choosing Jiaxing district water supply system, please look for the Shanghai Longya brand.
