A shaft seal water supply system and water supply method thereof

Abstract

The invention relates to a seal water supplying system and a water supplying method thereof. The seal water supplying system comprises a seal water pump A (5), a seal water pump B (6), a feeding pump A (12), a feeding pump B (11), a head water tank (1) and a technological water tank (16), wherein the feeding pump A (12) and the feeding pump B (11) are connected in parallel, and the situation that one feeding pump is used while the other feeding pump is standby is realized; seal water is supplied to the feeding pump A (12) by the seal water pump A (5), and seal water is supplied to the feeding pump B (11) by the seal water pump B (6); the seal water of the seal water pump A (5) and the seal water pump B (6) are both from the head water tank (1), and the technological water tank (16) is used for directly delivering water to the head water tank (1) to store or directly and respectively delivering the water to the seal water pump A (5) or the seal water pump B (6). According to the seal water supplying system, disclosed by the invention, the water in the technological water tank is used as a standby water source of the head water tank, and long-term and stable water storage of the head water tank can be ensured; in addition, the water can be directly imported to the seal water pumps by a clean water pump when the head water tank can not come into use.

Description

technical field [0001] The invention relates to a shaft seal water supply system and a water supply method thereof, in particular to a feed pump shaft seal water supply system and a water supply method used in the field of long-distance high-pressure slurry pipeline transportation. Background technique [0002] The feed pump is the key equipment in the field of long-distance high-pressure slurry pipeline transportation, and it belongs to the centrifugal pump type. The water supplied to the packing seal in the shaft seal system of the feeding pump plays the role of cooling, lubricating and sealing. The shaft seal water supply system is an important part of the shaft seal system of the feed pump. The stability of the shaft seal water supply system is to ensure the An important barrier for the safe operation of the pump. [0003] Such as figure 1 It is the traditional conveying process diagram of the existing shaft seal water supply system, and its working method is as follow...
