Gear pump reduces performance


The impact noise of the valve plate on the valve seat and the support part sucks a large amount of gas
The more circulating oil of the gear pump, the greater the valve noise, the higher the valve jump, the larger the valve area, the greater the noise of the valve, and the material of the valve has a certain influence. The noise of the rubber valve disc should be better than that of the steel sheet or laminate. For this reason, it is necessary to control the oil intake, and the valve flap must be closed in time and tightly. Pay attention to the selection and structure of the valve.
This noise will increase when the echo and bubble burst sound in the box increase.
Therefore, this noise will increase significantly when the gas ballast is turned on or when the atmosphere is vented. If the amount of gas ballast is adjustable, the amount of gas ballast can be adjusted reasonably.
The noise made when a large amount of gas and oil is discharged and hits the oil baffle and other parts
If the parts are not rigid enough or not fastened, vibration and collision will occur, which will increase the noise. Therefore, the oil baffle should not only have sufficient rigidity and be fastened, but also, when it needs to contact other parts (such as the fuel tank), the method of clamping rubber can avoid the collision noise caused by vibration and improve the oil blocking effect.
