Screw rod " stuck " phenomenon even occurs when serious, life-span and the efficiency of screw pump is greatly reduced, current most of bushings only exist
Connection sheet is provided with bushing import so that the situation for deforming, ftractureing occurs in use in bushing.
It is of the invention by the first connection sheet for described above, effectively increase the bonding pad of connection sheet and working chamber
Domain, by being provided with ring stiffener between the first connection sheet and the second connection sheet, and has additional at Bushing outlet the 3rd company
Contact pin so that bushing integrated stress more tends to be uniform, effectively reduces maximum stress and the strain of bushing, therefore, we carry
Go out a kind of three screw pump bushing.
The content of the invention
The technical problem to be solved in the present invention overcomes existing defect there is provided a kind of three screw pump bushing, connects by first
Contact pin, effectively increases the join domain of connection sheet and working chamber, by being provided between the first connection sheet and the second connection sheet
Ring stiffener, and have additional at Bushing outlet the 3rd connection sheet so that bushing integrated stress more tends to be uniform, effectively
Reduce maximum stress and the strain of bushing, the problem of effectively can solving in background technology.
In order to solve the above-mentioned technical problem, the invention provides following technical scheme：
The present invention provides a kind of three screw pump bushing, including housing, and the enclosure interior is provided with working chamber, the working chamber
One end goes out provided with bushing import and the first connection sheet being arranged on the outside of bushing import, the working chamber other end provided with bushing
Mouth and the 3rd connection sheet being arranged on the outside of Bushing outlet, connect between first connection sheet and the 3rd connection sheet provided with second
Contact pin, first connection sheet, the second connection sheet and the 3rd connection sheet are all fixedly connected with the casing, first connection sheet and the
Provided with a ring stiffener between two connection sheets and between the second connection sheet and the 3rd connection sheet, the ring stiffener with
Housing is fixedly connected.
As a preferred technical solution of the present invention, the working chamber is covered by a main circle and is respectively arranged on main circle and covers
The left bushing of both sides and right bushing are constituted, and the left bushing and right bushing intersect and left bushing, right bushing with main circle set respectively
It is interconnected with main circle set.
As a preferred technical solution of the present invention, the working chamber, bushing import, Bushing outlet, the first connection sheet,
Second connection sheet, the 3rd connection sheet and ring stiffener are integrally formed.
The beneficial effect that is reached of the present invention is：A kind of three screw pump bushing, by the first connection sheet, is effectively increased
The join domain of connection sheet and working chamber, by between the first connection sheet and the second connection sheet be provided with ring stiffener, and
The 3rd connection sheet is had additional at Bushing outlet so that bushing integrated stress more tends to be uniform, effectively reduces the maximum of bushing
Stress and strain, greatly improves operating efficiency.
