Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings and examples.
Please refer to fig. 1, the utility model provides a condensate pump with a split mechanical seal, which comprises a pump housing 12, a water inlet and outlet housing 1, a shaft seal chamber 2, a split mechanical seal 3, a fixing bolt 4, a split water retaining ring 5, a shaft sheath 6, a motor base 9, a thrust bearing 10 and a shaft 11.
When the pump set is installed, the shaft seal chamber 2 is installed on the water inlet and outlet shell 1, the shaft sheath 6 is installed on the shaft 11 through the screw 7, and then the thrust bearing 10, the motor base 9 and the like can be installed above the water inlet and outlet shell 1, so that the whole pump set is installed in place. Then the half-split mechanical seal 3 is arranged on a shaft 11 through a window 8 on the water inlet and outlet shell 1, the mechanical seal is fixed on the shaft seal chamber 2 by 4 fixing bolts 4, and finally the half-split water retaining ring 5 is arranged. When the mechanical seal is disassembled, the half water retaining ring 5 is firstly separated through the window 8, then the bolt 4 is screwed off, and the half mechanical seal 3 can be disassembled without disassembling other parts above the mechanical seal. The whole mechanical seal is disassembled and assembled only by operating through the window 8, and the operation is convenient.
As shown in fig. 2 to 4, the half-split mechanical seal 3 is composed of two mechanical seal bodies 17 and 18 which are completely mirror-symmetrical, and the two mechanical seal bodies 17 and 18 are respectively fixed together by eight screws 19, 20 and 21 at two sides after being respectively arranged on the shaft 11, so as to form an integral half-split mechanical seal 3. And then secured to the shaft seal chamber 2 by four bolts 4. In the same method during disassembly, only four bolts 4 are required to be unscrewed from the shaft seal chamber 2, and then eight screws 19, 20 and 21 are unscrewed, so that the whole half machine seal 3 is divided into two halves and is respectively taken out from the window 8.
As shown in fig. 5 to 6, the half-divided water retaining ring 5 includes two half-divided semi-circular rings 14 and 16 that are completely mirror-symmetrical, two bosses 13 are respectively provided at two ends of the upper surfaces of the two half- circular rings 14 and 16, and threaded holes 15 are drilled in the bosses 13 for fastening the two half- circular rings 14 and 16 with screws. When the two semicircular rings 14 and 16 are installed, the two semicircular rings are installed on the shaft 11, and then screws on two sides are screwed.
