Latch, latch is provided with screwed hole and passes through the spacing of nearly two latch of bolt pressure with coordinating with screwed hole.Pass through arc
The cooperation of shape inner ring and compression outer ring enables screen pack to be locked on oil-out, while also facilitating the replacing to screen pack, simply
Attractive in appearance, strong applicability, solid and reliable, difficulty of processing is low and conveniently, and element precision is easy to control, and reliability is high, moderate cost,
Performance is stable, and long lifespan, filter area is relatively large, is not easily blocked, good filtration effect, installation position is set low, makes the profit of hydraulic oil
With maximization is reached, it is difficult to be emptied in low oil level.
Preferably, arc-like inner band, which is provided with inner opening, inner opening, is provided with silica gel sealing pad and by silica gel sealing pad
It is connected to form closed-loop.By the setting of silica gel sealing ring, while mounting bar sealing is ensured, moreover it is possible to by compressing outer ring
Compressing makes arc-like inner band have adjustable performance, even if pump housing oil-out caliber has deviation, can also be coordinated.
Preferably, inner opening and outward opening are separately positioned on the both sides of mounting bar.
Preferably, screen pack, arc-like inner band and silica gel sealing pad are formed by integrated injection molding.
Preferably, screen pack provided with magnetic circle and pass through magnetic circle absorption oil in metallic particles.Pass through magnetic
Adsorbing metal particle is enclosed, destruction of the metallic particles to the pump housing is prevented.
The utility model is as a result of above technical scheme, with significant technique effect：Pass through arc-like inner band and pressure
The cooperation of tight outer ring enables screen pack to be locked on oil-out, while also facilitating the replacing to screen pack, simple and beautiful, applicability
By force, solid and reliable, difficulty of processing is low and conveniently, and element precision is easy to control, and reliability is high, and moderate cost, performance are stable, the longevity
Life length, filter area is relatively large, is not easily blocked, good filtration effect, installation position is set low, the utilization of hydraulic oil is reached maximum
Change, be difficult to be emptied in low oil level.
