高粘度齒輪計量泵在雙組份打膠機起到什么作用?
一 雙組份打膠機中打膠機出膠的穩(wěn)定與否決定了中空玻璃的生產(chǎn)質(zhì)量，下面就齒輪計量泵與其他型式泵的工作圖來分析。
The quality of hollow glass is determined by the stability of the glue discharging from the glue beater in a two-component glue beater. The working diagrams of the gear metering pump and other types of pumps are analyzed below.
齒輪計量泵：優(yōu)科齒輪計量泵采用漸開線齒形，經(jīng)變位修正，流量平緩均勻，無脈動。對于流量的調(diào)節(jié)只需調(diào)節(jié)泵的轉(zhuǎn)速即可，泵的流量于轉(zhuǎn)速成正比，調(diào)節(jié)簡單。
Gear metering pump: Youke gear metering pump adopts involute tooth shape, after modification, flow is gentle and uniform, no pulsation. For the flow regulation only need to adjust the speed of the pump can be, pump flow in direct proportion to the speed, simple regulation.
其他型式泵：（以柱塞泵為例）流量輸出是一股一股的，流量波動大，易造成出膠不均。
Other types of pumps: (take plunger pump as an example) flow output is one by one, flow fluctuations, easy to cause uneven glue.
二 泵對雙組份膠料的要求和密封方式
Two pump requirements for two component compound and sealing method.
齒輪計量泵：結(jié)構(gòu)簡單，并設(shè)有專門的清污槽，泵本身對大部分雜質(zhì)進行自清，泵亦可進行正反轉(zhuǎn)，進一步對雜質(zhì)進行自清，大程度上避免了顆粒雜質(zhì)對泵的影響。
Gear metering pump: simple structure, and has a special cleaning groove, the pump itself for most of the impurities self-cleaning, the pump can also be reversed, further impurities self-cleaning, to the greatest extent to avoid the impact of particle impurities on the pump.
其他型式泵：柱塞泵設(shè)有單向閥，單向閥對顆粒雜質(zhì)比較敏感，時間長易受污染，所以對密封膠料的清潔度要求很高。在密封方面柱塞泵多采用四氟材料，長時間工作，易磨損發(fā)生滲膠現(xiàn)象。
Other types of pumps: plunger pump with a one-way valve, one-way valve is more sensitive to particle impurities, long time vulnerable to pollution, so the cleanliness of sealant requirements are very high. In terms of sealing, the piston pump uses fluorine material more frequently, and works for a long time.

其他型式泵：使用其他型式泵時，當(dāng)A、B組份壓力不均時候，在調(diào)壓過程中，液壓站會升溫。
Other types of pumps: when using other types of pumps, when the pressure of components A and B is not uniform, in the process of pressure regulation, the hydraulic station will heat up.
齒輪計量泵：應(yīng)用齒輪計量泵時，由于獨特的設(shè)計使流量輸出無脈動，省去了液壓站及不必要的閥門和緩沖元件，使系統(tǒng)簡化，成本降低，性能提高。
Gear metering pump: When using gear metering pump, because of its unique design, the flow output does not pulsate, eliminating the hydraulic station and unnecessary valves and buffer components, so that the system is simplified, the cost is reduced, and the performance is improved.
