Summary

QZD s series water pump is made the internal new and original plumbing automatic control device of ware system voluntarily , and being this corporation collects many years water pump to produce , and applies experience controlled , and demonstrates repeatedly through expert , and optimizes the circuit , and designed meticulously , and among them many kinds of circuit are one of internal control electrical equipment the most first of present time .
For the use of cooperation water pump high efficiency and reliable , QZD s series is according to the needs of difference , has set up the liquid control mould , temperature control mould , time control mould and air-condition antithetical couplet seven big type such as accuse mould , latent dirt pump mould special and fire fighting control mould etc , each mould possesses respectively main return circuit short circuit and vacancy looks at and appraises and transships and the protection merit abilitys such as the pump aspect of pump special the lets out and super temperature of stator winding etc .
Moreover each mould divides again Shan Kongxing , hence many pumps owner uses and reserves the mutually accuse mould , owner and the accuse mould product  all has when barrier chiefly pump autonomous switchover fully mutually , and the merit ability of the automatic input of pump reserved
QZD s series controller merit can completely and the quality is reliable and the modelling is pleasing to the eye , and being various kind of necessary product that the water pump is ideal , and QZD s series controller especially is suitable in the production of industry and agriculture , municipal works , plumbing and fire fighting of high-rise , spurting the pours and automatic control of supercharge pump  the air-condition cools many kinds of occasions such as hot water DO loop pump control etc , and also is fit for the control of other alternating current generators  starting .
