Among the many equipment in the hydraulic station oil station, the gear pump CB-B200 plays a vital role. It is like a hard-working “energy messenger”, ensuring the efficient and stable operation of the entire system. The following is a detailed introduction to its working principle and how to help the oil station operate efficiently and stably.

1. Working principle

The gear pump CB-B200 mainly relies on the mutual meshing of internal gears to achieve fluid transportation. It has a pair of meshing gears inside, usually consisting of a driving gear and a driven gear.

When the motor drives the driving gear to rotate, the driving gear drives the meshing driven gear to rotate together. In the meshing area of ​​the gear, due to the effect of the gear profile, a local low-pressure area will be formed on the suction side. When the pressure on the suction side is less than the oil pressure in the tank, the oil in the oil station is sucked into the suction chamber of the gear pump under the action of the atmospheric pressure and the pressure difference in the tank. At this time, as the gear continues to rotate, the oil is gradually occupied by the tooth groove of the gear and is brought to the discharge side as the gear rotates.

On the discharge side, the meshing of the gears gradually turns the suction chamber into a closed space. As the gears rotate continuously and bring the oil from the suction chamber to the discharge chamber, the volume of the discharge chamber gradually decreases. According to the principles of fluid mechanics, when the volume decreases and the oil cannot easily flow into the area, the pressure of the oil will gradually increase. When the pressure reaches a level sufficient to overcome the resistance of the pipes and components in the oil station, the oil will be delivered to various parts that need lubrication or pressure through the oil outlet.

2. Ways to achieve efficient and stable operation of the oil station

Accurate flow control

The gear pump CB-B200 has good flow stability. The meshing accuracy of its internal gears is high and the structure is compact, so that under different working conditions, as long as the motor speed remains relatively stable, the flow of the gear pump can also remain relatively stable. This is crucial for the stable operation of the hydraulic station oil station. For example, in the lubrication system of the oil station, a stable lubricating oil flow can ensure uniform lubrication of each device, avoid insufficient or excessive lubrication of certain parts due to flow fluctuations, thereby extending the service life of the equipment and reducing wear and failure.

Efficient energy conversion

In the process of the motor driving the gear to rotate, energy can be efficiently transferred from the motor to the oil. The gear design and manufacturing process of the gear pump CB-B200 are optimized to reduce internal friction loss and leakage loss. For example, the high-precision gear surface finish treatment reduces the sliding friction of the gear during the meshing process; the reasonable gear structure design can effectively reduce the leakage of oil, so that more energy is used to promote the flow of oil, thereby improving the energy utilization efficiency of the entire thin oil station and reducing operating costs.

Reliable sealing performance

Good sealing performance is the key to the stable operation of the gear pump CB-B200 in the hydraulic station thin oil station. High-quality seals are used at all connection parts and inlets and outlets of the gear pump to prevent oil leakage. For example, the combination of mechanical seals and packing seals can not only ensure reliable sealing effect in high-pressure and high-viscosity thin oil environments, but also adapt to certain shaft movement and vibration working conditions. Effective sealing performance not only avoids oil waste and environmental pollution, but also ensures the stability of pressure in the thin oil station, providing stable lubrication and power support for the normal operation of various equipment.

Automatic pressure relief and overload protection function

When the pipeline or equipment of the hydraulic station oil station is blocked, the pressure is too high or other abnormal conditions occur, the gear pump CB-B200 has automatic pressure relief and overload protection functions. For example, when the outlet pressure exceeds the design rated pressure of the pump by a certain value, the pressure relief device in the pump will automatically open and return part of the oil to the suction chamber, thereby reducing the outlet pressure and preventing the pump body from being damaged by excessive pressure. At the same time, the motor overload protection device will also detect the abnormal increase of the motor current in time. When it exceeds the set value, it will automatically cut off the circuit to protect the motor and the entire pump body from damage, ensuring the safe operation of the oil station.

Good adaptability

The design of the gear pump CB-B200 fully considers the diversified working conditions of the hydraulic station oil station. It can operate stably in a wide temperature range and viscosity range. In a cold working environment, the viscosity of the lubricating oil in the oil station may increase, and the gear pump CB-B200 can still work normally. By reasonably designing the meshing curve of the gear and the internal channel size, the influence of viscosity on fluidity is reduced to ensure the smooth delivery of oil. In high temperature environment, the selection of materials and the design of sealing structure can also ensure the normal operation of the pump, avoiding problems such as material deformation and sealing failure caused by high temperature.

Gear pump CB-B200 provides a strong guarantee for the stable and efficient operation of the entire system in the hydraulic station oil station with its unique working principle and a series of performance advantages. Only by fully understanding its working principle and characteristics and carrying out reasonable maintenance and management can it better serve the operation of the oil station and ensure the safe and reliable operation of equipment in power plants and other places.
