The development trend of rubber diaphragm products – Chengdu’s high-tech can be divided into two categories according to the different working conditions and environmental protection of customers: one type of rubber, straight through type, U-type, flange type, and brand new type of diaphragm.
Ternary rubber: The best choice for extremely low temperature pumping, with a minimum temperature of minus 51 degrees Celsius. It can also be used for pumping dilute acids or low corrosive liquids.
Suitable for industries such as liquids, rubber, plastics, printing, coatings, inks, equipment, electroplating, plastics, aquaculture, etc. that are prone to corrosion, strong acids, strong alkalis, and contain suspended solids.
According to different diaphragm materials, choose different materials of diaphragms, which can also be divided into metal diaphragms, cast iron diaphragms, stainless steel diaphragms, cast iron diaphragms, plastic diaphragms, aluminum alloy diaphragms, hard diaphragms, O-rings, sealing rings, diaphragms, oil seals, high-pressure valves, three-way diaphragms, and special diaphragms.
The important principle of diaphragm pumps is that pneumatic diaphragm pumps are a new type of conveying machinery and are currently the most innovative pump type in China. Using compressed air as the power source, various corrosive liquids, liquids with particles, high viscosity, volatile, flammable, and highly toxic liquids can be pumped and absorbed completely; It has many advantages of conveying machinery such as self-priming pump, Submersible pump, canned motor pump, mud pump and impurity pump;
Diaphragm pumps can be divided into pneumatic diaphragm pumps, electric diaphragm pumps, pneumatic diaphragm pumps, cast iron diaphragm pumps, plastic diaphragm pumps, and normal operating media according to the power used by the actuator they are equipped with. For some solvents, liquids such as corrosion, abrasion, and casing produced by the diaphragm, they can be pumped and absorbed completely; It has many advantages of conveying machinery such as self-priming pump, Submersible pump, canned motor pump, mud pump and impurity pump; It can not only pump flowing liquid, but also transport some medium that is 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;
Pneumatic diaphragm pumps do not need to be lubricated with oil, and even if the air rotor pump is not large, regular inspection and replacement are required.
