Problems solved by technology
The problem brought about by the above situation is: since every second counts for disaster relief, otherwise it will delay the opportunity and cause the loss caused by the fire to expand. Before the fire pump is activated and the water is discharged, in order to drive the air in the pump, connect the vacuum pump to it. It takes time, and the work schedule of firefighters is tight and the work intensity is high

Embodiment Construction
[0020] please see figure 1 , the first pump body 1 as a vacuum pump is given, and one end of the first pump body 1 is currently represented by figure 1 The right end of the shown position forms a lubricating oil chamber 12, and the other end of the first pump body 1, that is, the left end shown in the figure, extends to form a connecting pump body 11, which uses a set of forcing members 112 (bolts) and The first sealing ring 113 is fixedly connected with the second pump body 6 as the fire pump, so that the vacuum pump and the fire pump form an integral body. The right end of the main drive shaft 2 as the vacuum pump (shown as an example, the same below) is rotatably supported on the first bearing seat 211 through the first bearing 21 , and the first bearing seat 211 is arranged on the pump cover 22 . The main drive shaft 2 is extended to the outer shaft end of the pump cover 22 with a flat key to fix the flange connection plate 23, and the flange connection plate 23 is used...

A coordination structure of a vacuum pump and a fire pump belongs to the technical field of the fire fighting device. The vacuum pump comprises a first pump body with a lubricating oil cavity, a main driving axle, an eccentric sleeve which is arranged on the main driving axle and positioned in the lubricating oil cavity of the first pump body, at least a pair of evacuation mechanisms and a self-lubricating sealing mechanism. The fire pump comprises a second pump body, a pump cover and a water pump impeller. The coordination structure is characterized in that one side of the first pump body which faces a pressure chamber of the second pump body extends and forms a connection pump body which is fixedly connected with the second pump body. The main driving axle stretches out of the connection pump body, enters into the pressure room and is connected with the water pump impeller. The self-lubricating sealing mechanism is arranged on the main driving axle and positioned in the connection pump body. The second pump body forms a first air passage which is communicated with the pressure room which is communicated with a second air passage which is arranged on the connection pump body and communicated with the evacuation mechanisms. The coordination structure has the advantages of saving time and lightening the field working strength of firefighters.
Description
technical field [0001] The invention belongs to the technical field of fire-fighting facilities, and in particular relates to a matching structure of a vacuum pump and a fire-fighting pump. Background technique [0002] The fire fighting vehicles are usually equipped with vacuum pumps and fire pumps. Since the vacuum pumps and fire pumps in the prior art are independent, when the fire trucks dispatch the police and arrive at the disaster relief site, the firefighters need to manually connect the vacuum pumps to the fire pumps. , so that the fire pump is evacuated by the vacuum pump until the fire pump discharges water smoothly. The problem brought about by the above situation is: since every second counts for disaster relief, otherwise it will delay the opportunity and cause the loss caused by the fire to expand. Before the fire pump is activated and the water is discharged, in order to drive the air in the pump, connect the vacuum pump to it. It takes time, and the work s...
