XBD fire pump installation knowledge

I believe everyone is familiar with the fire pump, especially for the XBD fire pump, but it is certainly not enough to know that the use of the fire pump, we can only master the installation skills, we can better repair, but also to ensure The service life of the fire pump has been extended, then, how to install it? Here's a brief introduction for everyone.

Compared with other fire pumps, the XBD fire pump has a more stable performance. When it is installed, it needs to have a certain understanding of its accessories. There are two types of pressure tanks, and of course, they have their own characteristics. The structure is relatively simple, but it is extremely efficient. Even if we inflate it once, we can use it for a long time. The other type is automatic replenishment, which can accurately regulate the water level and will not be limited by capsules. It can choose the appropriate pressure tank according to its own needs.

Another option is the centrifugal pump. Frequently used for DL ​​and SLS, the former is relatively stable and has a high lift. The latter is mainly because of its simple structure and low cost. If it is used regularly, It is recommended to choose the former, for this series of centrifugal pump contains two power interfaces that can automatically switch. During the installation and use, careful screening of circuit breakers, contactors, and relays is also required to ensure their ease of use.

The XBD fire pump has a relatively small volume, so it is not limited by the site and can be applied to various locations because the construction is relatively simple, so it is easy to manage and the investment is relatively small.
