It should be pointed out that the gap between the rotary vane and the groove is too large to reduce performance. Therefore, it is necessary to ensure reasonable tolerance matching and shape and position tolerance values, pay attention to the thermal expansion of the rotary vane, avoid the roughness of the rotary vane and the groove, pay attention to the cold oil viscosity of the oil, and design sufficient spring force of the rotary vane. When using circular arc separation , The additional eccentricity of the rotor center should not be too large. Otherwise, if the rotary vane passes through two circular arcs, it will tend to break away from the cylinder wall at the intersection point, which will cause impact noise. Generally, the size of the small gear pump is 0.20～0.25mm, and the large gear pump can be appropriately enlarged. Sound of pressure oil in the exhaust dead space and pressure oil in the residual volume. When the gear pump reaches the ultimate pressure, the two pressure oils will be injected into the vacuum chamber at high speed when connected with the vacuum chamber, colliding with the rotor and the cylinder wall to produce sound. The size and location of the two volumes are related to noise.The impact noise of the valve plate on the valve seat and the support part sucks a large amount of gasThe 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 partsIf 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.

Pinpointing Customer Addresses for Online Ordering in Wix Restaurants
What is address pinpointing?
When a customer orders delivery, we must locate their exact address to make sure it is covered by one of your delivery areas. Pinpointing requires your customers to enter a specific address that Google Maps recognizes.
When does pinpointing fail?
Unfortunately, some addresses are hard to pinpoint, and their location can only be approximated. This can happen for any of the following reasons:
A customer enters an incomplete address, e.g. a street address without a house number.
A customer has a non-standard address not recognized by Google Maps.
A customer requests delivery to a hotel or business and does not know the exact address.
What does my customer see if pinpointing fails?
If pinpointing is enabled and we can't locate an address on the map, your customer is asked to enter a different address.
Should I enable or disable pinpointing?
If you deliver mostly to areas with good map coverage, we advise you to leave pinpointing enabled. If you delivery to remote areas which are not fully covered by our map service providers, it is best to disable pinpointing to allow customers to enter approximate addresses.
To allow customers to enter an approximate address:
Click the Settings tab.
Click the Online Ordering tab.
Click the Pinpointing Addresses toggle.
Enabled: Customers who enter an approximate address are prompted to enter an exact address
Disabled: Customers will be allowed to enter an approximate address
During checkout, customers can add delivery instructions whether pinpointing is enabled or not.
