For the motor of the BRY hot oil pump when the lift head is too high
2024-03-06 10:07:13
For the high-lift BRY hot oil pump to use the motor under low lift, some people will not understand, it is considered that the motor is definitely not burning, but the efficiency is not as good as the head is high. For the BRY hot oil pump, the lift is too high for the motor. The effect is that the high-lift BRY hot oil pump will burn the motor under low lift. Some people will not understand that the motor is definitely not burning, but the efficiency is not as good as when the lift is high.
Only according to the actual use requirements, such as the actual flow rate, head, temperature, pipe length, pipe loss and other specific data to select the appropriate BRY hot oil pump, can ensure the normal operation of BRY hot oil pump.
Many customers believe that the lower the lift of the BRY hot oil pump, the smaller the motor load. Under the misunderstanding of this misunderstanding, when purchasing the BRY hot oil pump, the lift of the BRY hot oil pump is often selected very high. In fact, for the centrifugal hot oil pump, when the model of the BRY hot oil pump is determined, the power consumption is proportional to the actual flow rate of the BRY hot oil pump. The flow rate of the BRY hot oil pump will decrease with the increase of the lift, so the higher the lift, the smaller the flow rate and the smaller the power consumption. Conversely, the lower the lift, the greater the flow and the greater the power consumed. Therefore, in order to prevent motor overload, it is generally required that the actual pumping use of the BRY hot oil pump should not be less than 60% of the nominal head. Therefore, when the high lift is used for low lift pumping, the motor is easily overloaded and heated, and in severe cases, the motor can be burnt. If it is used in an emergency, a gate valve (or a small oil outlet plugged with wood or the like) for adjusting the oil output must be installed on the outlet pipe to reduce the flow and prevent the motor from being overloaded. Pay attention to the temperature rise of the motor. If Botaibang finds that the motor is overheated, it should close the flow rate of the oil outlet or shut down. This is also easy to misunderstand. Some operators think that blocking the oil outlet and forcibly reducing the flow will increase the motor load. In fact, on the contrary, the gate valve is installed on the outlet pipe of the regular high-power drainage and irrigation unit. In order to reduce the motor load when the unit is started, the gate valve should be closed first, and then the gate valve is gradually opened after the motor is started. I personally think that if this is used, the resistance will be smaller, the speed of the BRY hot oil pump will increase appropriately, so the flow will become larger, and the asynchronous motor will have less resistance, the speed will increase, the current will decrease, and the power will be less than the rated power. The motor will not burn at all, just a lighter load. Of course, this is not recommended, because its efficiency will be lower, because the design is used for high lift, the water output will be smaller under the same power conditions.
