Points to note when starting a high-pressure centrifugal liquid ammonia pump
Thread Content
Auxiliary equipment for high-pressure centrifugal liquid ammonia pumps (motor-driven) includes mechanical seal flushing water, inlet and outlet safety valves, etc. What are the things to keep in mind when starting up? I heard that high-pressure centrifugal liquid ammonia pumps are difficult to start; I would like to ask for advice from fellow sailors.
Starting a high-pressure liquid ammonia pump requires some care; if done improperly, it can cause the system to shut down. 1. As with ordinary centrifugal pumps, it is necessary to introduce ammonia and exhaust gas ； 2. Cold pump. Reflux cold pump – this is very important; the temperature must be reduced, otherwise the system will shut down once it starts operating ； 3. The oil circulation must be established in advance ； 4. The cooling water system should be turned on in advance.
Have you purchased high-pressure liquid ammonia centrifugal pumps? Which product is it, and when will it be put into operation? If it’s a foreign-brand product, don’t worry – the supplier will send someone to the site to guide the installation process. In case of need, domestic manufacturers also have established procedures for such installations.
