DBY electric diaphragm pump is a new type of volumetric pump that uses an electric motor to drive and delivers liquids through the reciprocating motion of the diaphragm. Its core feature is to use a diaphragm to completely isolate the conveyed medium from the transmission components, thereby achieving leak free conveying. This pump has the advantages of strong self-priming ability, the ability to pass through media containing particles, compact structure, and easy maintenance. It is mainly used for transporting various corrosive, flammable, explosive, high viscosity or solid particle containing liquids, widely serving industries such as petrochemicals, ceramics, metallurgy, environmental protection and food The core mechanical structure of the pump mainly includes the pump body, diaphragm, central connecting rod connecting the left and right diaphragm, inlet/outlet one- way valve controlling the unidirectional flow of liquid, and an electric drive system composed of a motor, gearbox, and crankshaft slider mechanism. The pump body usually contains two symmetrical chambers, and the diaphragm acts as a flexible elastic sheet to separate the fluid from the drive source. The working principle is to drive the diaphragm to move back and forth through a driving source (motor), causing alternating changes in the working chamber volume, and to achieve continuous suction and discharge of liquid in conjunction with a one-way valve. The specific working process is that the motor drives the diaphragms at the left and right ends to move back and forth through the gearbox. There are four one-way ball valves installed in the left and right pump chambers, and the movement of the diaphragms causes a change in the volume of the working chamber, forcing the four one-way ball valves to alternately open and close, thereby continuously sucking in and discharging the liquid. The DBY type electric diaphragm pump is driven by a motor, which is reduced by a cycloidal pinwheel reducer and then drives the double diaphragm to perform synchronous reciprocating motion through a crankshaft slider mechanism. This design makes the pump body structure compact. Due to the diaphragm separating the conveyed medium from the transmission mechanical components, it achieves no leakage of the medium and no shaft seal in the pump body, extending its service life

deep well pump is a type of pump submerged in groundwater wells for water extraction and conveyance. It integrates the motor and pump into a single unit and is widely used in agricultural irrigation and drainage, industrial and mining enterprises, urban water supply and drainage, and sewage treatment. Since the motor is also submerged in water, its structural requirements are more specialized than those of general motors. The motor's structural forms include dry, semi-dry, oil- filled, and wet types. Before starting the pump, the suction pipe and the pump body must be filled with liquid. Once the pump is operational, the impeller rotates at high speed, causing the liquid inside to spin along with the blades. Under the action of centrifugal force, the liquid is flung away from the impeller and ejected outward. The ejected liquid gradually slows down in velocity and increases in pressure within the pump casing's diffuser chamber, then flows out through the pump outlet and discharge pipe. At this point, a low-pressure vacuum zone devoid of both air and liquid forms at the center of the blades as the liquid is thrown outward. The liquid from the reservoir is drawn into the pump via the suction pipe under the influence of atmospheric pressure on the reservoir surface. Thus, the liquid is continuously and repeatedly drawn from the reservoir and discharged through the discharge pipe. Submersible pump components: consists of a control cabinet, submersible cable, discharge pipe, submersible electric pump, and submersible motor. In terms of medium usage, submersible pumps can be broadly categorized into three types: clear water submersible pumps, sewage submersible pumps, and seawater submersible pumps (corrosive) The QJ type submersible pump is a water extraction device where the motor and pump are directly connected and submerged in water for operation. It is suitable for extracting groundwater from deep wells and can also be used in water extraction projects such as rivers, reservoirs, and canals.

No special requirements for the well pipe or water lifting pipe (i.e., steel pipes, concrete pipes, earthen wells, etc., are all acceptable: under pressure, steel pipes, rubber hoses, plastic pipes, and the like can all be used as water lifting pipes). 3. Easy and simple installation, operation, and maintenance, with a small footprint, eliminating the need for a dedicated pump house. 4. The results are simple and save raw materials.

positive displacement pump A positive displacement pump is a type of positive displacement pump that delivers fluid through periodic changes in the volume of the internal chamber of the pump, with a relatively constant volume of liquid discharged per revolution or each reciprocating motion. Unlike centrifugal pumps, its flow rate mainly depends on the speed, and is less affected by changes in outlet pressure. The core principle of a positive displacement pump is "closed chamber delivery", where the fluid is enclosed in a specific space inside the pump and is "squeezed" from the suction end to the discharge end through mechanical motion. Volume change: When the internal structure of the pump (such as gears, screws, pistons) moves, the suction chamber volume increases to form negative pressure suction fluid, and the discharge chamber volume decreases to squeeze out the fluid. Single-way flow: Isolate the suction and discharge areas through one-way valves or engagement lines to ensure that the fluid does not flow back. Flow characteristics: In theory, the flow rate is proportional to the rotational speed, that is, the faster the rotation, the more fluid is discharged, and the flow rate remains relatively stable when the outlet resistance changes According to the different internal working parts, positive displacement pumps can be divided into various types, commonly used in the industrial, food, and pharmaceutical fields. Gear pump: using the rotation of two meshing gears to transport liquids, with a simple structure, suitable for low or medium viscosity media such as lubricating oil and fuel. Screw pump: Conveys fluid through the spiral cavity between the screw and the liner, with a stable flow rate, suitable for high viscosity liquids such as polymer melts. Piston/plunger pump: uses the reciprocating motion of the plunger in the cylinder to generate high pressure, commonly used for high-pressure cleaning and hydraulic systems. Diaphragm pump: changes the chamber volume through the reciprocating deformation of the diaphragm, suitable for conveying corrosive or particle containing media, with no risk of leakage. Rotary cam pump (rotary pump): Valve free design, conveying medium through a closed chamber formed by the rotor and pump casing, with strong self-priming ability. Pump advantages Positive displacement pumps have significant advantages under specific operating conditions Strong self-priming ability: No need to pump before starting, able to suck in liquid. Wide adaptability: capable of handling various complex media such as high viscosity, particle content, and corrosiveness. Pressure stability: When the outlet resistance increases, it can still maintain a constant flow rate until the mechanical limit. Precaution and pump protection: Overpressure risk: If the outlet valve is closed or the pipeline is blocked, the pump will continue to discharge fluid, causing a sharp increase in pressure, which may damage equipment or cause safety accidents. Safety measures: Pressure relief devices (such as safety valves) or interlocking systems must be installed to automatically release pressure when the pressure exceeds the set value, preventing overpressure. Maintenance requirements: When transporting high viscosity fluids, the speed should be limited to avoid inaccurate flow or cavitation caused by unfilled suction ports.

Centrifugal pump with self priming device The core principle of converting a conventional centrifugal pump into a self- priming pump is simply: It is to ensure the pump can retain water after shutdown and automatically expel air from the suction pipe upon startup.The key to modification liesThe not in altering the impeller, but in installing two essential systems—the "water storage" and "gas-liquid separation" mechanisms—into the pump body. 1. Maintain priming: For ordinary centrifugal pumps, water must be filled before each start-up as the water in the pump casing and suction pipe will drain out. During modification, install a check valve(non-return valve) at the inlet to allow water to flow in but not out. After shutdown, water can remain in the pump body and suction pipe, eliminating the need for refilling during the next startup 2. Air Removal: Simply retaining water is not enough—there is still air in the suction pipe. Self-priming pumps rely on an air-water separation chamber: the impeller mixes water and air into an air-water mixture and ejects it. When the mixture enters a cavity with suddenly increased volume, the flow velocity drops sharply, causing the air to rise and be discharged through the outlet while the water falls back to continue the cycle. After several repetitions, the air in the suction pipe is completely removed, and water rises The core method for converting a centrifugal pump into a self-priming pump involves installing a foot valve or check valve in the suction pipe, along with improvements to the pump body sealing and priming system Common modification methods Install a foot valve or check valve: Install a foot valve at the bottom of the suction pipe or inlet to prevent water backflow and ensure the suction pipe remains fully filled with water. Install an automatic suction device: Add a water collection pipe at the inlet and an air-water separator at the outlet to achieve automatic air venting. Set up the water suction tank: Install a negative pressure water tank or filling chamber, ensuring sufficient liquid is retained for next startup Key modification steps Improve the shaft seal: Replace the cast iron bushing with a brass bushing and use a mechanical seal kit (static ring, dynamic ring, spring, etc.) to ensure the sealing performance of the rotating shaft. Pump Body Modification: Install a stationary ring sleeve and rubber gasket in the packing chamber, machine threads at the impeller shaft end to match the spring seat, and sequentially install the sealing kit. Pipeline Connection: All components must be tightly sealed, with no air leakage in the suction and drainage pipelines Precautions Initial Water Filling: Before startup, fill the pump body with water, then close it after expelling air through the vent valve. Sealing Inspection: Regularly check the wear condition of the pump body and impeller, and promptly replace worn components. Installation Position: The pump should be installed as close as possible to the liquid source, with the inlet pipe kept as short as possible to minimize flow resistance

Slurry pumps and sewage pumps are two distinct types of pumps, primarily differing in their application scenarios and structural design. Slurry pumps are mainly used for slurry transportation and treatment in industrial production, while sewage pumps are primarily employed for urban drainage and wastewater treatment. The usage scenarios of slurry pumps and sewage pumps differ. Slurry pumps are primarily used in industries such as mining, chemical processing, construction, and metallurgy for slurry transportation and treatment. Slurry is a liquid containing a high concentration of solid particles, and using ordinary water pumps for its conveyance can easily lead to pump clogging or damage. Therefore, slurry pumps feature specialized structural designs to effectively transport high-concentration, high-viscosity slurries. In contrast, sewage pumps are mainly employed for urban drainage and wastewater treatment. Urban sewage contains significant amounts of organic matter and microorganisms, which, if not promptly discharged and treated, pose substantial risks to the environment and human health. Sewage pumps can lift wastewater from low-lying areas to higher elevations or transport it away from urban zones for further processing and disposal. 2. The structural design of slurry pumps and sewage pumps also differs. Slurry pumps typically adopt a centrifugal or plunger pump structure, which ensures high efficiency and stability when transporting slurry. The impeller and pump body of slurry pumps are made of special materials resistant to wear and corrosion in slurry. In contrast, sewage pumps usually employ a centrifugal or submersible pump structure, maintaining high efficiency and durability when handling sewage. The impeller and pump body of sewage pumps are also constructed with special materials to resist corrosion and clogging in sewage.

The main types of pump impellers include channel type (single channel, double channel), blade type (closed, open), spiral centrifugal, and vortex type. The flow path impeller features a curved flow channel formed from the inlet to the outlet within the impeller. This design makes the flow path impeller particularly suitable for pumping liquids containing large particulate impurities or long fibers, demonstrating excellent anti-clogging capability. However, in comparison, its anti-cavitation performance is somewhat inferior, falling short of other types of impellers. Impeller with blades The casting process for semi-open and open impellers is relatively simple, and they are easy to maintain and clean to remove blocked impurities. However, their drawback is that during transportation, solid particles gradually increase wear on the inner walls of the volute chamber and the gaps between the blades, thereby reducing the pump's operational efficiency. Additionally, this wear can disrupt the flow stability of the liquid in the passage, causing pump vibration. Therefore, this type of impeller is not suitable for conveying media containing large particles or long fibers. In comparison, closed impellers offer higher operational efficiency and can run smoothly for extended periods, with relatively lower axial thrust. However, it should be noted that closed impellers are prone to clogging, making them unsuitable for pumping sewage media containing large particles or long fibers. Helical/ spiral centrifugal impeller The design feature lies in its twisted blades, which extend from the suction inlet toward the axial direction along the conical hub body. This design ensures that the transported liquid does not collide with any other components inside the pump when flowing through the blades, thereby avoiding potential damage to the pump while maintaining non-destructive handling of the liquid. Thanks to the helical propulsion effect, the impeller exhibits excellent particle suspension capability, making pumps equipped with this type of impeller particularly suitable for pumping media containing large particles and long fibers. Vortex impeller The design feature of the vortex impeller is that its blades are partially or entirely recessed from the flow passage of the volute, endowing it with excellent anti-clogging performance. During the pump's operation, particles are driven by the vortices generated by the impeller's rotation within the water pressure chamber. Notably, the movement of these suspended particles does not generate energy but instead exchanges energy with the liquid in the flow passage. This design ensures that suspended particles or long fibers do not directly contact the blades during flow, significantly reducing blade wear and eliminating issues of clearance enlargement caused by abrasion. Consequently, the vortex impeller is particularly suitable for pumping media containing large particles and long fibers.
