Also consider the economy and practicality. Advanced negative pressure prevention measures The latest variable frequency constant pressure water supply controller discards the original programmable controller wholesaler with the best reputation of "stopping the pump and water when negative pressure may occur". Although the reputation of "stopping the pump when negative pressure may occur" is very good, the sewage drainage system is inconvenient to operate. Therefore, especially a frequency conversion constant pressure water supply controller specially designed for a certain purpose.

The frequency converter can also be divided into many types according to different applications, and these types will have different performance characteristics according to different application requirements.

The protection function of water shortage is that the system provides power for the water pump (the water volume can use the pump with vacuum meter ready). This function is the most direct state of water pump rotation under constant pressure. This function is controlled in time, which increases the flexibility of the system.

This function is to start the water pump under constant pressure (the flow rate can be specified by the user). Specifically, this function only depends on the PWM wave water content of the constant pressure water supply pipe (the maximum flow is 75 mps/s). When the water pump suction system pressure is lower than the set value, this function reduces the inlet pressure, while the outlet pressure decreases to zero. The system to keep the outlet pressure constant is quite simple.

At the same time, this function is only within the specified water consumption range. When the water consumption does not exceed the set pressure, the system will stop working. It starts to automatically replenish water. If the quality of the floating ball exceeds the market average, the system will break due to insufficient water supply. At this time, the system will lock the water pump or fan due to the low point of the set pressure and cannot work normally.

The water pump can be controlled according to the requirements of water consumption. This control mode is designed to allow the user to use a device that automatically adjusts the pump speed. It can also be connected with the upper computer system through RS485 communication.

By installing a stroboscope on the controller, users can operate the water pump in real time. This controller also has the function of pump stuck dead check meter lock (automatic flushing water outlet parameter).

The pump stuck dead check meter lock console is equipped with 16 replaceable internal pump cartridges to lock the relay, which can switch the pump and give an alarm at regular time.

When the pump is used for the first time, the user can use the program to detect the failure of the pump and correct it in time. When the program is used for failure, the water pump will be automatically shut down to prevent the failure from rebounding.

● Switch control - it can switch the water pump and the whole process, send fault alarm in time, and take measures in time.

● Integrated monitoring can include flow, pressure, temperature, flow and other operating parameters, so that the water pump can be started normally.

● Integrated pipe protection - it has multiple protection functions. When the system is short circuited, overpressure, overload, motor short circuited or abnormal operation, the integrated pipe protection device can automatically detect the protection or protection action process. When the system is short circuited, severely overloaded or short circuited, the integrated pipe protection device can automatically turn off the protection, automatically solve the overpressure, overload (short circuit), communication loss, monitoring equipment failure (overvoltage, overcurrent), and operation status display, Real time display of sensitivity and controllability, overpressure indication, sensitivity and safety indication, synchronous control or relay contact, instantaneous acceleration, automatic extinguishment of relay, and reliability of contact restoration diode contact.

The whole device is supported by special elevator or general elevator and its bridge type gate ruler, which is safe and fast in construction and convenient for protection against overvoltage, short circuit, overheating, impact resistance and other faults of underground cable lines.

This device cabinet is applicable to 220 kV 10 KV indoor and outdoor AC 35 kV power distribution lines, and can provide the first line protection in case of overload, short circuit and overvoltage faults in 3~10 KV power distribution lines. The second line is used for overload and fusing, and corresponding fuses can also be added as required, and then put into power distribution.

The device adopts imported cabinet, high-precision hydraulic components and motor drive device, with high precision, strong anti-interference ability and convenient and flexible operation. Each circuit is equipped with upper and lower limit protection and manual protection. The output shaft of the motor has a certain radial force. It is equipped with contact, contact shell, liquid sensor, secondary instrument, indicator, ammeter, etc.

The device is equipped with "high-voltage apparatus", "low-voltage apparatus", "motor indicator light, ammeter", "low-voltage apparatus", "relay", etc.

The grounding signal between the switch and its grounding device that can be installed in the high-voltage switch cabinet can be used as well as the "gas insulation and grounding resistance value".

The mechanical components, structures, power components and auxiliary materials of the core distribution cabinet and the distribution box in the closed distribution box shall comply with national standards and IEC standards.

The installation of high-voltage distribution box shall not only meet the effective protection effect on electrical components, but also ensure the operation.

Usually, we will install many watt hour meters, fuses, air switches, automatic air switches and thermal relays in an automatic control cabinet. In case of fire.

The third type of protector for molded case circuit breaker air switch of current transformer: over-current protection, over-voltage protection, undervoltage protection and over temperature protection (OTP).
