Product Overview

SHKseries pump control cabinet is well-designed product, of which electricalcomponents from international and domestic brand-name to ensure product quality,on basic of experience of pump control applications for many years, with referenceto international and domestic standards, and constantly improve optimization.

SHKseries of electrical control cabinet according to the different needs andoccasions, set liquid-level control, pressure control, temperature control,time control, air conditioning control, special fire control, with manual andautomatic start and stop function, also with protection function of overload,short circuit, phase, overcurrent and stator windings pump leaks andoverheating,meantime with function of starting standby pump automatically whenmain pump faults..

SHKseries of electrical control cabinet is reliable, durable, perfect companion ofvarious types of pumps. This product is widely used in agricultural production,urban water supply and drainage, residential district water supply, fireprotection, automatic spray pressurized circulating pump and HVAC control andboiler feed pumps and other occasions, but also applies to other types of ACmotor control.

Functional advantages

1.High-efficient& energy-saving: As a result of constant pressure variable, variabletransformer supply system, the pump is always working in the best energy-savingstate, means to increase the output power when large water consumption, and toreduce the output power when small water consumption, the output power can be automaticallyadjusted by water consumption. Also, due to the pump flow and speed isproportional, and be 3 party between speed and power, it is a significant power-saving.Energy consumption can be reduced to 51.2% when the flow drops to 80% (80%rated pump).

2.Stableand reliable operation and high degree of automation: core components of specialcontroller for water supply, converter of good quality, mature technology, highstability, be adapt to harsh working environment. Unmanned operation can beachieved, which will help manage.

3.System is running with low noise, stable pressure and high control accuracy.

4.Equipmentintegrated variety of protection functions: over-current, over-voltage,overload, phase loss, stall, phase unbalance power, water and other waterprotection.

5.Multiple pumps alternately can be recycled to run: balancing the averageworking hours of multiple pumps, to avoid of pump corrosion and stuck. 

6.Prolong life: soft-start of multiple pumps to reduce wear and tear on machineryand equipment instant consumption.
