The following is the introduction of Salami double gear pump summarized by LEXMUA
Features and application of Salami double gear pump
Features:
Salami double gear pump has the characteristics of simple structure, light weight, long-term maintenance of high volumetric efficiency, and reliable use;
The double gear pump has a floating bushing structure and an automatic compensation function for axial clearance. The unique wear-resistant formula of the sleeve provides a long service life;
Carefully machined gears ensure the use of Salami gear pump under low noise conditions;
The cold-drawn profile pump body can withstand the pressure above 30Mpa;
The high-strength cast iron front and rear covers make the Salami gear pump work more reliably.
Application:
Salami gear pump can be widely used in construction machinery, hoisting and transportation machinery, mining machinery and agricultural machinery, aerospace, shipbuilding, marine engineering and other hydraulic systems.
Salami double gear pump structure
Salami duplex gear pumps are mechanically linked in the middle and rotate simultaneously when activated. The double gear pump has 2 oil outlets, and an unloading valve, or an electromagnetic overflow valve, or a two-position two-way electromagnetic reversing valve, etc., can be added to each oil outlet to unload one of the oil pumps. , becomes the idling state.
Working principle of Salami double gear pump
Double gear pumps are suitable for transporting lubricating liquids that do not contain solid particles, are non-corrosive, and have a large viscosity range.
Salami double gear pump is a rotary pump that relies on the change and movement of the working volume formed between the pump cylinder and the meshing gear to deliver liquid or pressurize it. A pair of intermeshing gears and a pump cylinder separate the suction chamber from the discharge chamber. When the gear rotates, the volume between the teeth at the side of the suction chamber where the teeth disengage from each other gradually increases, the pressure decreases, and the liquid enters the space between the teeth under the action of the pressure difference. As the gear rotates, the liquid between the teeth is brought to the discharge chamber. At this time, the volume between the teeth at the side of the discharge chamber where the teeth mesh gradually decreases, and the liquid is discharged.
