Qingdao Haitongda Special Instrument Co., Ltd. Qingdao Haitongyuanda Special Instrument Co., Ltd. Drilling Fluid Analytical Instruments Special Pressure Gas Source device The special pressure gas source device is a device for automatic pressure control and is used in multiple high-pressure instruments manufactured by our company. It can be used with HTD18984 Permeability Plugging Tester and provides more stable and reliable gas source instead of hand-operating pressure pump. It can provide a constant 4-way automatic pressure at most and apply pressure to four high pressure instruments simultaneously. It consists of two pneumatic pumps and four hydraulic self-adaptive regulators that can achieve automatic pressure regulation. Besides, there are gas-liquid booster, precision pressure regulator, precision liquid filter, safety protection system, etc. The wide-range precision pressure regulating valve can regulate the pressure automatically via the high-pressure duct system. Special Pressure Gas Source Device HTD17981 Primary pressure gauge--displaying the total pressure available for 1~4 regulators; Fluid reservoir opening valve--supplying nitrogen to the top reservoir; Hydraulic governor--providing pressure to the testing unit; Air governor--controlling the air pressure of the pump; Hydraulic pressure gauge--indicating the pressure inside the testing unit.
