Why do gas dispensers make noise and vibrationWhy do gas dispensers make noise and vibrationWhy do gas dispensers make noise and vibration

The noise and vibration of the fuel dispenser during operation may be caused by various factors. Here are some main reasons and their detailed explanations:

1、 Internal factors of equipment

The filter screen of the oil and gas separator is blocked

Reason: Blockage of the filter screen can cause poor oil flow, increase the load on the vane pump, and thus generate noise and vibration.

Solution: Regularly clean or replace the oil and gas separator filter to ensure smooth oil flow.

Blade pump issue

The overflow valve of the vane pump is stuck or improperly adjusted: If the overflow valve is stuck and cannot be opened or the adjustment screw is too tight, it will cause abnormal pressure inside the pump, resulting in noise and vibration.

Blade jamming of vane pump: Blade jamming can increase the pulsation of output oil, causing noise and vibration in the machine.

Damage to blades or springs: Damage to blades or springs can also affect the normal operation of the pump, leading to increased noise and vibration.

Solution: Check and repair the vane pump, including cleaning or replacing components such as relief valves, blades, and springs, to ensure the normal operation of the pump.

electrical noise

Reason: The motor itself may have faults or wear, resulting in increased noise.

Solution: Check the working status of the motor and replace it with a new one if necessary.

2、 External factors

Oil pipeline issues

Long and thin pipelines: Long pipelines can increase the resistance to oil flow, while thin pipelines can cause excessive flow velocity, both of which can increase the load on the vane pump and generate noise and vibration.

Improper bending or installation of pipelines: Improper bending or installation of pipelines may result in poor oil flow, vortex and impact, leading to noise and vibration.

Solution: Optimize the layout and size of oil pipelines to ensure smooth oil flow and reduce eddies and impacts.

Fixed problem

Loose corner bolt: If the fuel dispenser is not securely fixed, loose corner bolts can also cause noise and vibration during machine operation.

Solution: Regularly check and tighten the corner bolts to ensure that the fuel dispenser is securely fixed.

3、 Resonance phenomenon

The pulsation frequency of the output oil is close to the natural frequency of the fuel dispenser: when the pulsation frequency of the output oil is close to the natural frequency of the fuel dispenser, resonance occurs, resulting in increased noise and vibration of the fuel dispenser.

Solution: Adjust the overflow valve of the vane pump or replace the damping pad between the oil and gas separator and the frame to change the natural frequency of the system and avoid resonance phenomenon.

In summary, the generation of noise and vibration in fuel dispensers may involve multiple aspects, including internal and external factors of the equipment, as well as resonance phenomena. In order to reduce noise and vibration, it is necessary to regularly inspect and maintain the fuel dispenser to ensure the normal operation and reasonable layout of all components. At the same time, attention should also be paid to the influence of external environment, such as the layout and fixation of oil pipelines.
