Pump control cabinet with overload, short circuit, the lack of phase protection and the pump body water leakage, motor over-temperature and leakage and other protection features and complete state display, and have a single pump and multi-pump control mode, a variety of main pump switching mode And various types of starting. Can be widely used in industrial and agricultural production and various types of construction of water supply, drainage, fire fighting, spray pipe network booster and HVAC hot and cold water circulation and other occasions, the pump automatic control. Typical application of pump control cabinet: constant pressure water supply, fire fighting, sprinkler, central air conditioning, water supply and drainage, port machinery, machine tools, boilers, paper machinery, food machinery. Pump control cabinet control type: 1, level control: The control cabinet with high-performance float switch, according to the level of high and low changes, automatic control of the drain pump open, stop. 2, Pressure control: External electric contact pressure gauge or pressure controller, according to the pipe network pressure changes automatically open the pump, off the pump, this type is widely used in domestic water supply and fire booster systems. 3, temperature control: external temperature controller, according to set the temperature range to open the pump or off the pump, used in constant temperature, heat exchange system temperature control and other occasions. 4, time control: the chassis panel has a time setting button and display, the user can control the timing needs of the pump on and off, for a variety of regular or regular intermittent work control. Pump control cabinet start mode Direct start, star delta buck start, auto buck start, soft start and frequency start. Use should be based on power supply conditions and other factors to choose the appropriate start-up mode. Pump control cabinet Features: 1, fire pump control cabinet Fire pump control cabinet points fire hydrant control cabinet, automatic spray control cabinet and fire pump control cabinet, etc., can be divided into one with a preparation and two with a preparation. Working pump failure standby pump delay automatically put the pump by the fire hydrant box buttons, current relays, pressure switches and fire control systems, water alarm. And has a working state (manual, automatic) selection switch, signal indication and feedback. Can be equipped with fire inspection and other functions. 2, life to the pump (constant pressure water supply) control cabinet Life to the pump (constant pressure water supply) control cabinet sub-level control cabinet, pressure control cabinet and constant pressure frequency control cabinet, can be divided into one with a prepared, two prepared with a standby. Working pump failure standby pump delay automatic input, the pump from the tank water level control, pressure gauge control and remote control system control, constant pressure water supply pipe network pressure through the remote pressure gauge or pressure transmitter test, the output 4 -20mA or 0-10V to the inverter, the inverter adjusts the pump speed according to the signal to meet the requirements of the pump flow, so as to realize constant pressure variable water supply and save energy. And has a working state (manual, automatic) selection switch, signal indication and feedback. Water source alarm and automatic stop pump protection. 3, hot water circulation pump control cabinet Hot water circulating pump control cabinet can control one or more pumps, generally one with a prepared, two each alternate, working pump failure standby pump automatically, you can also rotate the work. Pump temperature control or remote control. And has a working state (manual, automatic) selection switch, signal indication and feedback 4, frozen (cooling) pump control cabinet Refrigeration (cooling) pump control cabinet control multiple pumps, are generally alternate to each other, work rotation, work pump failure standby pump automatically into the controller or remote control. And has a working state (manual, automatic) selection switch, signal indication and feedback 5, drainage pump control cabinet Drainage pump control cabinet can control one or more pumps, usually one with a prepared, each alternate, working pump failure standby pump automatically. Controlled by single level or multi level control can also be remote. High water level start, low water level stop pump, high with the Kai, automatic rotation and so on. And has a working state (manual, automatic) selection switch, signal indication and feedback. Pump control cabinet technical parameters: 1, start the control cabinet directly Control motor power: 0.37-15KW; Control voltage: 380V; Control the number of pumps: 1-4 units. 2, Star delta buck start control cabinet Control motor power: 15-160KW; Control voltage: 380V; Control the number of pumps: 1-5 Taiwan. 3, self-buck control cabinet Control motor power: 15-160KW; Control voltage: 380V; Control the number of pumps: 1-5 Taiwan. 4, soft-start, frequency control cabinet Control motor power: 0.18-250KW; control voltage: 380V; Control motor number: 1-7 Taiwan; Pressure control accuracy: 0.02MPa or -0.02MPa 5, conditions of use Power supply: electricity, self-provided power grid, diesel generator sets; three-phase AC 380V, (- 10%, + 15%), 50HZ Applicable motor: general squirrel cage induction motor Starting frequency: for frequent start, it is recommended not more than 20 times per hour Degree of protection: IP41 or IP20 Pump control cabinet Environmental conditions: Altitude not more than 2000 meters (more than 2000 meters should derating use), the ambient temperature between -25 ℃ --- +40 ℃, the relative humidity of not more than 95%, no condensation.
