Usually, the factory will encounter insufficient air pressure and need pressurization to meet the equipment requirements (such as gas assisted injection molding, valve detection, thimble hot runner, etc.), at this time, the gas pressurization equipment will be used. At present, domestic supercharging equipment is divided into electric supercharging equipment and pneumatic supercharging equipment, which have their own advantages and disadvantages. The following is an explanation for pneumatic supercharging equipment.
The principle of the gas booster pump is very simple. It is really difficult to achieve a good product. If you don't talk much, you will understand its principle by taking a look at the structure of the gas booster pump. The pneumatic booster pump is divided into two parts: the driving cylinder and the booster cylinder. The two cylinders are separated independently, which does not affect the purity of the gas. The pneumatic drive must have the piston moving back and forth, The low-pressure driving gas drives the large piston to move back and forth to generate power to drive the small piston of the booster cylinder to squeeze the gas in the booster cylinder. Check valves are connected at the inlet and outlet of the pressurized gas to prevent the backflow of the pressurized gas and complete the gas pressurization process.
After understanding the working principle of the gas booster pump, let's understand the reason why the gas booster pump is equipped with an air storage tank?
Because of the pneumatic gas booster pump itself, the pressurized gas is not output all the time, but output one by one like the piston air compressor, which will lead to the abnormal use of some equipment because of the pulse. At this time, an air storage tank is needed to alleviate the impact of the pulse and the large flow demand of instantaneous release.
So how to match the air tank is more appropriate? This involves how much flow and pressure the pneumatic booster pump pressurizes every minute. Generally, the pressure resistance of the air storage tank should exceed the high pressure generated by the booster pump. Second, it should be noted that the size of the air storage tank should correspond to the flow of the pneumatic booster pump. For example, if the flow of feinte ztv02 is 1200L / min, the 20L air storage tank will be small, resulting in frequent operation of the booster pump, Increasing the workload of the booster pump will affect the service life of the booster pump. Less 40L air tank is required to give him a buffer. Third, pay attention that the interface of the air tank should not affect the use flow because the interface is too small. For example, the flow of feiente ztv02-3 is 4000L / min, and you use a three-point inlet, then the instantaneous gas output from the booster pump to the air tank is less than 4000L / min, so it is meaningless for you to configure ztv02-3.
