Introduction: Most of the fire to provide water for fire water, fire water pump pressure needed to meet fire and water when water pressure requirements. Pump as set, and inadequate maintenance have problems and will certainly affect the fire fighting and rescue, resulting in unnecessary losses.

Recently, vehicle maintenance repair shop in the process discovered that some vehicles are not in place as water pump system maintenance equipment of vehicles and equipment on duty against the phenomenon. Failure mainly due to the situation at the water pump no water pumps are idle and time to dry grinding impeller state, causing severe wear the pump, mechanical seal, Vice damage, resulting in vehicles stopped a long time and brought against the increase in maintenance costs. Vice damage which the main types of mechanical seal overheating damage, mechanical damage. Thermal damage is a long time idling pumps, dry friction, the formation of high temperature and pressure within the pump, the door suddenly opened a large tank section, flow through the sudden drop in temperature, likely to cause mechanical seal Vice hot cracking and deformation. Mechanical damage is not through the filter with water, solid particles penetrated sealing surface, so soft sealing surface wear and then burst damage, there are frequent opening and closing water pump mechanical seal pair relative movement caused by wear and tear.

It is understood that the Beijing Fire Department a total of 5 sets liberate 7 flat wood fire engines and 19 fire engines equipped with 153 pumps equipped with mechanical seal pumps Luxembourg and Asia, the series of factory water pump is basically discontinued, spare parts difficult to buy and the price expensive, only the first wife of a mechanical seal pair valued at more than 9,000 yuan, a process must achieve more than 2000 yuan.

Fire pump tips: Q: The need for multi-storey building dedicated to fire pump?

Under the changes, set up a temporary high-pressure fire water supply system of buildings, should be set up fire water tank. These structures for the 4,5-level multi-storey building, the pressure of the municipal pipe network is generally 20 to 30 m water column, the most negative point of fire hydrants to meet the water column needed to substantiate the need for such construction should also set fire pump. However, the multi-storey buildings set fire hydrant system is intended only for the initial fire fighting, a lot of fighting and rescue work should rely on the city fire department, fire pump setting for this bit of a waste is inevitable. For this type of construction, I wonder if you can learn from high-rise buildings set on fire water tank outlet pipe pressurized practice facilities, the outlet pipe in the water tank set on fire through fire hydrant box button or by fire on the tank outlet pipe Start the booster pump flow indicator to meet the substantial needs of the water column. This approach, booster pump located at the roof, is the light-load start, start fast, on the initial fire fighting should be favorable.

In addition, in the municipal pipe network to meet the water inside and outside the premise of the fire, I wonder if you can consider according to the different uses of the building to determine whether to set fire pump. That is, plant and large public buildings, to promote the establishment of fire pumps to have a certain self-help skills, within the general residential, may be allowed no fire pumps, fire, fire engines used in outdoor fountain pump adapter fire, after all, even in residential buildings equipped with a fire pump, not necessarily to the proper use of the residents.
