详细介绍

FAT-GD系列气液增压泵驱动活塞直径为160mm， 为了保证气液增压泵的寿命，建议使用气压≤8bar。凡是接触液体部分材质根据介质不同选碳钢或不锈钢，泵的全套密封件均为产品，从而保证了泵的性能。

Detailed introduction

The diameter of driving piston of fat-gd series gas-liquid booster pump is 160mm. In order to ensure the service life of gas-liquid booster pump, it is recommended to use air pressure ≤ 8bar. Carbon steel or stainless steel shall be selected for the materials of the parts contacting the liquid according to the different media, and the complete set of seals of the pump are imported products, so as to ensure the performance of the pump.

其特性同FAT-G系列泵相同，但与同规格G系列泵相比，脉冲小且流量比G系列单作用泵提高50％。

Its characteristics are the same as those of fat-g series pumps, but compared with G series pumps of the same specification, the pulse is small and the flow is 50% higher than that of G series single acting pumps.

工作原理：气液增压泵工作时，利用单气控两位四通阀来实现柱塞或活塞的快速自动往复运动，随着输出压力的增高后，泵的往复减慢直至停止，此时，泵输出的压力恒定，能量消耗为零，各部件停止运动，泵体气驱部分全部采用铝合金制造并氧化处理成黑颜色保证了产品的外型美观，进出液部分材质均选用不锈钢，适用水、油、乳化液等介质，泵的全套密封件均为优良产品，从而保证了泵的性能，很大驱动气压10bar，为了保证泵的寿命，建议使用气压3-8bar。压缩空气很大消耗量1.0立方/分钟，压力平衡后不再消耗压缩空气。

working principle:

When the gas-liquid booster pump works, the single air control two position four-way valve is used to realize the rapid and automatic reciprocating motion of the plunger or piston. With the increase of the output pressure, the reciprocating motion of the pump slows down until it stops. At this time, the output pressure of the pump is constant, the energy consumption is zero, and all components stop moving, The gas drive part of the pump body is made of aluminum alloy and oxidized into black color to ensure the beautiful appearance of the product. The material of the inlet and outlet part is stainless steel, which is suitable for water, oil, emulsion and other media. The full set of seals of the pump are imported high-quality products, so as to ensure the performance of the pump. The maximum driving air pressure is 10bar. In order to ensure the service life of the pump, it is recommended to use air pressure of 3-8bar. The maximum consumption of compressed air is 1.0 m3 / min. compressed air will not be consumed after pressure balance.

增压比为驱动活塞面积/柱塞杆截面积

表中流量为驱动气压在6bar、出口压力为零、介质为水时泵的近似流量，介质粘度越大，流量越小。

The boost ratio is the drive piston area / plunger rod cross-sectional area

The flow in the table is the approximate flow of the pump when the driving air pressure is 6 bar, the outlet pressure is zero and the medium is water. The greater the medium viscosity, the smaller the flow.

产品特点如下：

输出压力高：液体输出压力可高达400Mpa。

适用：工作介质可为液压油、水及大部分化学腐蚀性液体，而且可靠性高，免维护和寿命长

输出：对所有型号泵仅需较小气压就能平稳工作,此时获得小的流量，调节进气量后可获得不同的流量。

应用灵活：选用不同型号的泵，可获得不同的压力区域。

易于调节：在泵的压力范围内，调节调节阀从而调节输入气压，输出液压相应得到无级调整

自动保压：无论何种原因造成保压回路压力下降，赛思特泵将自动启动，补充泄漏压力，保持回路压力恒定。

操作：采用气体驱动，无电弧及火花，可在危险场所使用。

维护简单：与其它的气驱泵比较，赛思特泵可完成同样的工作，但其零件及密封少，维护更简单。

The product features are as follows:

High output pressure: the liquid output pressure can be as high as 400MPa.

Applicable: the working medium can be hydraulic oil, water and most chemical corrosive liquids, with high reliability, maintenance free and long service life

Output: for all types of pumps, only a small air pressure can work smoothly. At this time, a small flow can be obtained. Different flows can be obtained after adjusting the air intake.

Flexible application: different types of pumps can obtain different pressure areas.

Easy to adjust: within the pressure range of the pump, adjust the regulating valve to adjust the input air pressure, and the output hydraulic pressure can be adjusted steplessly accordingly

Automatic pressure holding: no matter what causes the pressure drop in the pressure holding circuit, the cester pump will start automatically to supplement the leakage pressure and keep the circuit pressure constant.

Operation safety: gas driven, no arc and spark, can be used in dangerous places.

Simple maintenance: compared with other gas drive pumps, cester pump can complete the same work, but it has fewer parts and seals, making maintenance easier.
