Interior mechanical lubrication effect.
In above-mentioned slinger, the gear oil clot includes bending part one and bending part two, and the bending part one is relatively curved
Folding part two is obliquely installed, and the upper friction pair of the bending part two towards mechanical seal is arranged, and the bending part one inclines with link block
Tiltedly setting, the angle between the bending part one and link block is obtuse angle.
So that gear oil clot further realizes guiding role to the direction of lubricating oil, and bending is arranged in the setting of the structure
Portion one and bending part two have also buffered lubricating oil to the impact force of gear oil clot, have improved the stability that slinger uses.
In above-mentioned slinger, the end face of the end face of described two one end of bending part and bending part one in obtuse angle, the end face
It is arranged towards pump shaft.
The lubricating oil for flowing to bending part two can be oriented to towards pump shaft, enable lubricating oil further by the setting of the structure
Towards mechanical seal upper friction pair flow, improve the mechanical lubrication effect of the pump housing.
In above-mentioned slinger, the angle between the bending part one and bending part two is obtuse angle.
The setting of the structure has buffered lubricating oil to the impact force of bending part one and bending part two, while can to lubricate
Oil can be thrown away further up, and flow to the upper friction pair of mechanical seal, improve the mechanical lubrication effect of the pump housing.
In above-mentioned slinger, the bending part one is equipped with the resigning recess placed for mechanical sealing chamber cavity.
The setting of the structure, so that the setting of bending part one closer to pump shaft, is realized and made to the guiding of most of lubricating oil
With further improving the mechanical lubrication effect of the pump housing.
In above-mentioned slinger, there are two the oil baffle is set, two oil baffles are arranged radially along pump shaft.
The setting of the structure can carry out guiding role to lubricating oil radial, improve the mechanical lubrication effect of the pump housing
Fruit.
Compared with prior art, this slinger has the advantage that: the direction by keeping off oil clot, so that lubricating oil direction is mechanical
The upper friction pair of sealing flows, and then realizes the lubricating action to the upper friction pair of mechanical seal.
