The invention relates to the technical field of fire safety, in particular to an emergency water suction pump for fire safety. The pump comprises a mounting frame, a water pump and a control box, thewater pump and the control box are sequentially and fixedly arranged on the mounting frame from left to right, a filter frame is arranged at a pipe orifice at the bottom of a water suction pipeline ofthe water pump, and a pressure sensor is arranged on the water suction pipeline of the water pump. A pressure transmitter is arranged on a water feeding pipeline of the water pump, and a PLC, a relayand a frequency converter are sequentially and fixedly arranged on the inner wall of the left side in the control box from top to bottom. The pressure sensor is arranged on the water suction pipelineof the water pump, when the pressure value in the water suction pipeline exceeds the set value, it is indicated that the water suction pipeline is blocked, the PLC automatically controls the relay tobe powered off, the water pump is prevented from being damaged, and the water pressure can be monitored in real time by arranging the pressure transmitter on the water supply pipeline of the water pump; and constant-pressure control over water supply of the water pump is achieved by adjusting the power of the frequency converter, and the water suction pump is suitable for being used and popularized.
Description
technical field [0001] The invention relates to the technical field of fire safety, in particular to an emergency water pump for fire safety. Background technique [0002] In a fire accident, if there is no clean water source on site, water needs to be pumped to the site water source. The existing water pump cannot achieve effective debris filtration and effective constant-pressure water supply. Therefore, a fire-fighting Use emergency sump pump for safety. Contents of the invention [0003] The purpose of the present invention is to provide an emergency water pump for fire safety. By setting a pressure sensor on the water pump pipe, when the pressure in the water pipe exceeds the set value, it means that the water pipe is blocked, and the PLC controller automatically controls the relay to turn off. Electricity, to avoid damage to the water pump, by installing a pressure transmitter on the water supply pipe of the water pump, the water pressure can be monitored in real ti...
