Abstract
Water supply pump is the heart of automatic sprinkler system and should start reliably when there is on fire. But because sprinkler system and automatic fire alarm system related to linkage control of water supply pump are designed by different manufacturers and installed by skillful staffs in different fields, there are accident potentials existing in the low reliability linkage control. The failure probability of extinguishment system is higher. In this paper, research on reliability and linkage control of automatic sprinkling pump system has been carried out. Intermediate link has been eliminated. Strong and weak electricity are isolated. Automatic and manual controls are combined. Redundancy technique is used. A linkage control system for water supply pump with high reliability and economical efficiency has been designed. Our achievement has been applied in many fire fighting systems and the linkage control system of water supply pump is proved to be safe and reliable.
