Fig. 3 is a connection diagram of the utility model in practical use.
Wherein: 1. the pump body connecting section 2, the middle section 3, the separator connecting section 4, the pump body connecting threaded hole 5, the gasket groove 6, the chamfer 7, the separator connecting threaded hole 8, the negative pressure pump rotating body 9, the negative pressure pump rotating shaft 10, the water-gas separator 11, the separator rotating body 12 and the bolt.
Detailed Description
The present invention will be further described with reference to specific embodiments and drawings thereof, and it will be understood that the embodiments described are only some embodiments of the present invention and not all embodiments.
As shown in fig. 1 to 3, a rotary shaft detachable from a negative pressure pump includes: pump body linkage segment 1, middle section 2, separator linkage segment 3. The diameter of pump body linkage segment 1 is greater than 2 diameters in the middle section, sets up pump body connecting thread hole 4 in the pump body linkage segment 1, pump body connecting thread hole 4 is used for connecting the pump body pivot 9 that passes pump body rotator 8, replaces the fixing bolt of negative pressure pump pivot 9 in the negative pressure pump simultaneously. The pump body connecting section 1 is provided with a gasket groove 5, the gasket groove 5 is arranged at the outermost end of the pump body connecting section 1, and the pump body connecting section 1 is provided with a chamfer 6. The separator connecting section 3 is designed in a flat key shape, so that the connecting transmission between the rotating shaft which can be disassembled from the negative pressure pump and the separator 10 is facilitated. The separator connecting section 3 is internally provided with a separator connecting threaded hole 7, and the middle section 2 is arranged between the pump body connecting section 1 and the separator connecting section 3. The water-gas separator 10 further comprises a water-gas inlet, a gas outlet and a water outlet, and the water-gas separation is realized by adopting a centrifugal force principle.
It should be noted that, because the utility model discloses a main aim at embodies one kind can be dismantled in being connected of negative pressure pump's pivot and moisture separator and can play the effect of transmission shaft, as for the moisture separator's that utilizes centrifugal principle work concrete structure and its theory of operation belong to prior art, right technical field's technical personnel, as long as satisfy the moisture separator of above-mentioned requirement all can use, the user can directly purchase even on the market, consequently is in the utility model discloses do not do too much and describe repeatedly.
One kind can dismantle when being connected in the pivot of negative pressure pump and moisture separator, one kind can dismantle in the relative screwing up direction of negative pressure pump pivot 9 and negative pressure pump pivot 9 of the pivot of negative pressure pump opposite with the work direction of rotation of negative pressure pump pivot 9, that is to say can not make because of the work of negative pressure pump pivot 9 when negative pressure pump pivot 9 works one kind can dismantle in the pivot of negative pressure pump and drop with negative pressure pump pivot 9, on the contrary, in the work of negative pressure pump pivot 9, one kind can dismantle in the pivot of negative pressure pump and be connected more and more tightly between negative pressure pump pivot 9. Similarly, the screwing direction of the rotating shaft and the bolt 12 which can be disassembled from the negative pressure pump is opposite to the working rotating direction of the rotating shaft which can be disassembled from the negative pressure pump, namely, when the rotating shaft 9 of the negative pressure pump works, the rotating shaft which can be disassembled from the negative pressure pump and the rotating shaft 9 of the negative pressure pump rotate towards the same direction, and at the moment, the connection between the rotating shaft and the bolt 12 which can be disassembled from the negative pressure pump is more and more tight.
The specific working principle is as follows: the end cover bolt of the existing negative pressure pump is detached, the pump body connecting section 1 detachable from a rotating shaft of the negative pressure pump is used for replacing the end cover bolt of the negative pressure pump, the pump body connecting section 1 is connected to the rotating shaft 9 of the negative pressure pump through the pump body connecting threaded hole 4, meanwhile, the separator connecting section 3 penetrates through the separator rotating body 11 of the water-gas separator 10, the separator connecting section 3 is fixed in the separator connecting threaded hole 7 through the bolt 12, and connection between the separator connecting section 3 and the water-gas separator 10 is achieved.
When the length of the rotating shaft which can be disassembled from the negative pressure pump is changed due to the need of replacing the water-gas separator, the rotating shaft which can be disassembled from the negative pressure pump and the water separator can be replaced by only disassembling the water-gas separator 10 and then disassembling the rotating shaft which can be disassembled from the negative pressure pump rotating shaft 9. Simple operation and low cost.
To sum up, the utility model discloses reach anticipated purpose.
