Based on the magnetic coupling principle, it consists of a driving magnetic yoke and a driven magnetic yoke. When the external motor drives the driving magnetic yoke to rotate, through the action of magnetic lines of force, the driven magnetic yoke rotates accordingly, thus achieving contact - less transmission.
Inside the magnetic gear pump, meshing gears are installed on the driving magnetic yoke and the driven magnetic yoke respectively. When the gears rotate, the liquid enters the gear clearance from the suction end of the pump and is pushed to the discharge end as the gears turn, realizing the continuous transportation of oyster sauce.
Usually, motors such as servo motors and brushless motors are used as the driving source. Through the transmission device, the rotational motion of the motor is transmitted to the magnetic gear pump, providing power for filling.
As the core component of the filling machine, it is responsible for extracting and quantitatively transporting oyster sauce. The pump body is generally made of 316 or 316L stainless steel, and the gears are made of PEEK, a high - strength engineering material, which has good corrosion resistance and wear resistance.
It is used to store the oyster sauce to be filled. Usually, it has a relatively large capacity to ensure the needs of continuous filling.
It is composed of pipelines and valves. It is the passage for oyster sauce to enter the target container from the liquid storage tank. Precise filling is achieved through the control of the valves.
Generally, a PLC control system and a touch - screen human - machine interface are adopted. Parameters such as filling volume, filling speed, and intermittent time can be easily set. At the same time, the operating status of the equipment can be monitored in real - time.
Through the accurate metering of the magnetic gear pump and the precise adjustment of the control system, high - precision filling can be achieved. The filling error can be controlled within a very small range, generally reaching ±1% or even higher precision.
The magnetic coupling design completely isolates the inside and outside of the pump. There is no need for mechanical seals, effectively preventing the leakage of oyster sauce. This not only ensures product quality but also avoids environmental pollution.
It can adapt to oyster sauces of different viscosities. Even for high - viscosity oyster sauce, stable and smooth filling can be achieved. At the same time, it can be compatible with various specifications and shapes of packaging containers, such as glass bottles and plastic bottles.
The filling speed is fast. Multiple filling heads can be equipped to work simultaneously, greatly improving production efficiency and meeting the needs of large - scale production.
Due to the relatively simple structure of the magnetic gear pump, with few components, and the contact - less transmission reducing friction and wear, the maintenance work of the equipment is relatively simple, reducing maintenance costs and downtime.
On large - scale oyster sauce production lines, the fully automatic magnetic gear pump oyster sauce filling machine can achieve efficient and accurate filling, ensuring product quality and production efficiency. It is an important equipment for enterprises to improve their market competitiveness.
In addition to oyster sauce, some food processing enterprises can also use this filling machine to fill other products such as sauces and oils during production, achieving multi - purpose use of one machine and improving the utilization rate of equipment.
