Walter joined the water pump control cabinet Equipment Co. Merchants national agency, secondary water supply equipment sailing toward the beautiful areas of pump control cabinet is mainly applicable to all types of industrial and agricultural production and construction of water supply, drainage, fire sprinkler pipe pressurized and HVAC and hot water pumps and other occasions automatic control. Device Overview pump control cabinet with overload, short circuit, phase protection and pump leakage, multiple motor overtemperature protection and leakage, etc. and complete status display, and with a single pump and multi-pump control mode, a variety of primary and secondary pumps switching mode and various start-up mode. It can be widely applied to various types of industrial and agricultural production and construction of water supply, drainage, fire sprinkler and HVAC pipe pressurized hot water circulation pump to automatically control a variety of occasions. Typical applications: constant pressure water supply, fire protection, sprinkler, central air conditioning, plumbing, port machinery, machine tools, boilers, paper machinery, food machinery. Type 1 control, level control: the control cabinet with a high-performance Key float switch, according to high and low level changes, the automatic control to open the drain pump, stop. 2, the pressure control: external pressure gauge or pressure controller automatically pump according to changes in pressure in the pipe, and shut the pump, this type widely used in domestic water and fire booster systems. 3. Temperature control: external temperature controller, according to the set temperature range pump or off pump, used in case of need temperature control thermostat, the heat exchange systems. 4. Time control: time setting chassis panel has buttons and display, the user may need to control the timing of the pump is turned on and off, for a variety of timed or regular control of intermittent work. Characteristics of a start mode to start the pump control cabinet is divided into: full-voltage starting, star delta reduced voltage start, auto-down, soft start and frequency start. Should select the appropriate startup mode power supply based on factors such as the use of the conditions. 2, the main loop pump control cabinet main route back to the isolation circuit, short-circuit protection, overload (backup) protection circuit, start and stop (speed) control of electrical, thermal relays and power distribution cables and other components to form effective protection for the pump motor. Demand set all kinds of monitoring signals. Scope 1, factories, industrial and domestic water supply, fire protection, sewage and other control 2, buildings, shopping malls and other air-conditioning cooling water control 3, guesthouses, four bathrooms and other water control, automatic water control city square musical fountain
