1. Introduction
The equipment can observe the system of changing pressure. Pressure sensor is according to signal and the setting pressure to measure data respectively, output signal will be sent to the special frequency converters. Frequency converter is according to the changeable signal sent by sensor to change the frequency (0-50Hz). With the changing frequency, motor pump change the speed to keep constant pressure.
2, Automatic computer control (ordered by customers)
a. Adopting micro processor intelligent to control
b. Power manager chips made in America. Quality assurance.
c. Water pump operating and stop function can be controlled for a long distance.
d. To be on the safe side, avoid contacting with water pumps (or close contact).
3. Function:
a. Pressure setting, operate on the sensor directly.
b. Water pressure loss protection function: Motor will be stopped running controlled by controller when there is shortage of water.
c. Protective function: Over-voltage, over-current, over-load limit, over-heat, over-voltage, high- voltage, grounding protection , abnormal contact input
4, Application scope
1st,General family, Small high-rise, senior villas, hotel and some place where need constant pressure water supply or other places where have no water tower and poor need to add pressure.
2nd, The sites have not secondary pollution water quality.
3rd, Residential houses’ secondary pressure. Other places which have not enough water pressure, frequency, pressure adding is needed.
4th.Use in cold weather (using temperature: 75ºC max), hot water(using temperature: 120 ºC max)
