Booster pump, as its name implies, is used to boost the pump, mainly for water heater booster, high-rise low pressure, sauna, bath and other pressurized, the apartment under the pressure of the top of the water pressure, solar energy Automatic pressurization, reverse osmosis water purifier pressurization, etc., play an important role in daily life. However, some faults often occur in the operation process, so it is very important to understand some precautions of the operation of the booster pump. alert! Booster pump operation considerations Booster pump operation precautions Booster pump operation process, the operator should strictly observe the position, strengthen the inspection, timely detection of problems and timely manner. Under normal circumstances, should pay attention to the following matters. 1. Check all kinds of instruments work is normal, such as ammeter, voltmeter, vacuum gauge, pressure gauge. If found readings too large, too small or violent beating, should promptly identify the reasons to be ruled out. Sudden increase in vacuum gauge readings may be caused by blockage of the water inlet or decrease of the water level in the inlet tank. If the pressure gauge reading suddenly drops, the water inlet pipe may leak, air may be drawn in, or the speed of rotation may decrease. 2. Pipeline booster pump operation, packing tightness should be appropriate. Gland too tight, stuffing box infiltration is too little, can not get water seal, lubrication, cooling, easy to cause the filler heating, hardening, to speed up the pump shaft and sleeve wear and increase pump mechanical loss; packing pressure is too loose , Excessive water seepage, resulting in a large number of leaking, or air into the pump to reduce the volumetric efficiency of the pump, resulting in reduced water, or even water. Under normal circumstances, the packing tightness of 20 minutes per minute seepage is appropriate, gland packing thread can be used to adjust. 3. Bearing temperature rise generally should not exceed 30 ~ 40 ℃, the maximum temperature shall not exceed 60 ~ 70 ℃. Bearing temperature is too high, will make lubrication failure, burned bearings or cause rolling body rupture, and even lead to broken shaft or shaft thermal expansion and seizure of accidents. When the temperature is too high, stop the car immediately to check the cause and eliminate it in time. 4. To prevent the circulating booster pump inlet submerged depth is not enough, resulting in the vortex near the inlet, so that air into the pump. Should promptly clean the trash rack and into the pool floating objects, so as not to block the inlet pipe. Both of these will increase water resistance, resulting in a decrease in inlet pressure and even cavitation. 5. Note that the oil ring, to make it free to do with the pump shaft do not sync rotation. At any time to listen to the unit sound is normal. 6. Stop the front of the valve to close the gate, the implementation of closed parking. Then, close the vacuum gauge and pressure gauge valve, wipe the pump and motor surface water and oil. In the absence of heating equipment in the house, after stopping in winter, to consider the pump will not freeze. Industry Internet (Xiamen) Technology Co., Ltd.
