rolling diaphragm cylinder 归档 - GENERAL SEALTECH LIMITED

Insight into the future trend of the rolling diaphragm industry, inspire the picture of the innovative wisdom driven pneumatic diaphragm pump, and adopt the production and processing of NBR, Neoprene, fluorocarbon, EPDM rubber, fluororubber, polytetrafluoroethylene, food rubber and other industries.

The high-purity aluminum alloy pneumatic diaphragm pump adopts, absorbs, and improves the internationally advanced production process and technology of pneumatic diaphragm pumps. This product is specially designed for coal mines and has all the functions of traditional submersible electric pumps, mud pumps, impurity pumps, and flexible shaft pumps. It is a revolution of traditional mining water pumps. The key is to completely solve the safety problem of the traditional water pump. The product can provide a very high delivery speed under Low-pressure area, and is compatible with a wide range of materials. This water pump has a stall resistant design and modular Pneumatic motor fluid part.

The pneumatic diaphragm pump adopts a meter oil cylinder and a cut-off diaphragm, which has fast oil recovery speed, small pressure loss, easy operation, and simple opening and closing of gas valves. Even if there is no medium operation for a long time or sudden shutdown due to unexpected circumstances, the pump will not be damaged, which can ensure safety. And the pneumatic diaphragm pump is equipped with the original pump valve, gear pump, rotor pump, and pneumatic diaphragm pump. It has many advantages of conveying machinery such as self-priming pump, Submersible pump, canned motor pump, mud pump and impurity pump.

Vertical pneumatic diaphragm pump: Pneumatic diaphragm pump is a new type of conveying machinery that uses compressed air as the power source. For various corrosive liquids, liquids with particles, high viscosity, volatile, flammable, and highly toxic liquids, it can be pumped and absorbed completely; It has a reasonable structure.

The pneumatic diaphragm pump has six advantages: reliable quality, long service life, low noise, low vibration, never crash, and fine workmanship. It can not only pump flowing liquid, but also transport some media that are not easy to flow. It has many advantages of conveying machinery such as self-priming pump, Submersible pump, canned motor pump, mud pump, and impurity pump.

No need for irrigation and water diversion, with a suction head of up to 5m, a lift of 50m, and an outlet pressure of ≥ 6kgf/cm2;

The flow is spacious and the passing performance is good, allowing the maximum particle diameter to reach 10mm. When pumping mud and impurities, there is minimal wear on the pump;

The head and flow rate can be adjusted steplessly through the opening of the air valve (the air pressure can be adjusted between 1-7kg/cm2).

Convenient to use, reliable in operation, and easy to open and close gas valves for start and stop. Even if there is no medium for a long time or sudden shutdown due to unexpected circumstances, the pump will not be damaged. Once overloaded, the pump will automatically stop, with self-protection performance. When the load returns to normal, it can automatically start and run;

The pump has a simple structure and fewer vulnerable parts. It is easy to install and maintain, and the medium conveyed by the pump will not come into contact with moving parts such as the distribution valve and connecting rod. Unlike other types of pumps, the performance gradually decreases due to wear and tear of rotors, pistons, gears, blades, and other components;

This pump does not require oil lubrication, and even if the rotor is empty, the pump will not be damaged. Once overloaded, the pump will not automatically stop and has a self-protection function.

The hydraulic system of manned submersibles generally adopts an underwater pressure compensator to avoid the influence of water pressure． GENERAL SEALTECH LIMITED think as the key structural parameter，the inner diameter is the biggest factor influencing both peak values．The larger the inner diameter，the smaller the peak of the pressure difference inside and outside the Rolling diaphragm．

Rolling diaphragm

Based on the design principle that the peak of pressure difference should be less than the safe working pressure of Rolling diaphragm，the boundary constraint and valuing method of the inner diameter of a compensator was attained． Based on the key parameter，which is the inner diameter of a compensator，the compensator can be designed accurately and reliably． This method has been widely used in some deep－sea vehicles． Practical application shows that the method is feasible and effective．

The hydraulic system of manned submersibles generally adopts an underwater pressure compensator to avoid the influence of water pressure.

In the 1960s, the United States began to develop manned submersibles. The underwater hydraulic technology developed rapidly. The pressure compensation technology relied on a pressure compensator. The pressure compensators currently available have a bladder type, a bellows-type and a rubber diaphragm type. In the pressure compensator, the bladder, bellows and compressed air bottle are suitable for compensating the cavity whose volume does not change. It is called static compensation. Only the rubber diaphragm pressure compensator is suitable for compensating the volume change cavity. The rubber diaphragm is divided into a flat diaphragm, a corrugated diaphragm, and a rolling diaphragm, and the flat diaphragm has a small compensation amount; then, the underwater hydraulic system belongs to a volume change cavity, so a rubber diaphragm pressure compensator should be used. The wave diaphragm has a large amount of compensation, but it can be deformed and deformed into a serious nonlinearity; the rolling diaphragm is good, the stroke is large, and the deformation resistance is small.

Therefore, the rolling diaphragm pressure compensator is widely used in the current deep-sea equipment, China The hydraulic system of the “JiaoLong” manned submersible uses a rolling diaphragm pressure compensator for compensating the volume change chamber, so it is often integrated with the fuel tank design, and the compensator is used as a hydraulic system tank. The entire hydraulic system can also be pressure compensated. The designed rolling diaphragm provides reliable quality and technical support for the pressure compensator design.
