Flood control emergency mobile hand lift diesel fire pump

In civil buildings, there are many types and quantities of electrical equipment, not only fire fighting equipment such as fire pumps and sprinkler pumps. In order to meet the reliability of power consumption of these devices, when the municipal power grid cannot provide two independent power sources, the method of using diesel generator sets as a backup power source in the design is widely used.

The so-called auxiliary impeller hydrodynamic seal of diesel engine fire pump refers to the installation of an open impeller in the opposite direction coaxially near the back of the impeller rear cover plate of the diesel engine fire pump. When the diesel engine fire pump is working, the auxiliary impeller rotates with the main shaft of the pump, and the liquid in the auxiliary impeller also rotates together, and the rotating liquid will generate an outward centrifugal force. pressure at the mechanical seal. On the other hand, the solid particles in the medium are prevented from entering the friction pair of the diesel engine fire pump seal, and the wear of the mechanical seal grinding block is reduced. In addition to the sealing function, the auxiliary impeller of the diesel engine fire pump can also reduce the axial force.

    The role of the mobile pump truck:

    As an important supplement to fixed pumping stations, mobile pumping stations can be used in flood control and drainage, drought and seedling protection, urban flood control, aquaculture, temporary water transfer, cofferdam pumping, industrial drainage, municipal drainage, etc. The mobile pumping station is a unit that combines the pump and the motor closely together for submersible operation. my country’s submersible pumps have undergone four stages of development. By the 1990s, the types, varieties, output and quality of the pumps were relatively stable. Because the submersible electric pump has the advantages of simple structure, convenient use, etc., and the continuous improvement of the power grid, it has been widely used. Submersible electric pumps only need outlet pipes, so welded steel pipes, rubber hoses and rubber hoses (similar to fire hoses) have certain applications.

    The mobile pump station plays an important role in drought resistance and seedling protection. In the event of a drought, in remote areas without fixed pumping stations or when the flow of fixed pumping stations is insufficient, the unit fails or the water level is too low and fixed pumping stations cannot operate, the characteristics of mobile pumps’ strong mobility can be fully utilized to mobilize a large number of pumps in a short time Station to solve the drought. Drought resistance and seedling preservation generally take a long time to run, but the time requirement for reaching the job site is not high.
