Maintenance and maintenance of operational multi-stage fire pumps
Aqueducts shall be sealed at a high level and shall not leak or leak
2. To prohibit the long-term operation of multi-stage fire pumps in a corrosive state
3. When multi-stage fire pumps operate under high-flow conditions, it is prohibited to operate electricly driven excess power for long periods of time
4. Periodic inspection of electrically motivated current values during the operation of pumps and attempts to make the pumps work under design conditions
5. Multigrade fire pumps should be supervised by the operator in order to avoid accidents。
6. Multi-grade fire pumps shall be refuelled for bearings once each 500 hours of operation
7. After the long operation of the multi-stage fire pumps, the noise and vibration of the equipment will increase as a result of mechanical wear and tear. Should stop and check it. It is necessary to replace vulnerable parts and bearings. The pump usually has a major overhaul period of one year。
Multi-grade fire pumps
Maintenance and maintenance of mechanical seals
Mechanical sealed lubricants shall be clean and free of solid particles
2. Work in conditions of dry grinding is strictly prohibited
3. Multi-stage fire pumps (electrical motors) shall be rotated several times before they are activated in order to avoid damage from the break-up and sudden activation of mechanical seals。
Building on the original single-grade fire pumps, we have developed a new generation of multi-stage fire pumps for steady pump products, based on standard requirements for multi-grade pumps. The range of fire pumps meets the requirements for fire pumps in terms of performance, structure, materials and accessories. Thanks to excellent hydro-modelling, the series meets user requirements; the introduction of a vertical pump structure is characterized by efficiency and wide range of performance, which saves ground space. The use of high-quality bearings and high-quality electric power sets the operation of the pumps to be safer and reliable, with little noise and little vibration; the use of hydraulic pressure to balance the direction of the axis will make the operation more stable; and the axle seals will be in the form of mechanical seals and filling seals. The pump also has the characteristics of imported, exported, fast-paced, light weight, etc。
