Basic Introduction to DBY Electric Diaphragm Pump

DBY electric diaphragm pump is a type of pump that has made breakthrough progress in diaphragm materials in recent years and has been applied in industries such as petrochemicals, ceramics, metallurgy, etc. Its characteristics are that it does not require water injection and has strong self-priming ability. The diameter of the Shanghai edge will be separated by the conveying medium and transmission mechanical components, so the medium will never leak outward. And the pump itself has no shaft seal, greatly extending its service life. Application areas: Diaphragm pumps have taken an absolute dominant position in the painting and ceramic industries; It is expanding its market share in environmental protection, wastewater treatment, construction, sewage, and fine chemicals, and has an irreplaceable position compared to other pumps.

The main purpose of DBY electric diaphragm pump

1. Various highly toxic, flammable, and volatile liquids.

2. Various strong acids, strong alkalis, and highly corrosive liquids.

3. Can transport media with higher temperatures up to 150 ℃.

4. As a front-end pressure feeding device for various filter presses.

5. Hot water recovery and circulation.

6. Oil tanker trucks, oil depots, and oil loading and unloading.

7. Pump kimchi jam, mashed potatoes, chocolate, etc.

8. Pump paint, gum, pigment adhesive.

9. Various porcelain glazes, cement grout, mortar slurry.

10. Various rubber pastes, latex, organic solvents, and fillers.

11. Use a pump to clean and extract sewage and residual oil from the oil tanker barge.

12. Hops and fermented powder slurry, syrup, and molasses.

13. Pump sewage and sediment from mines, tunnels, tunnels, and sewers.

14. Suction and delivery of various special media.

The working mode of an electric diaphragm pump is only available when selecting a pneumatic actuator, and its working mode is formed by the combination of the positive and negative actions of the actuator and the valve. There are four types of combinations, namely positive positive (gas closing type), positive negative (gas opening type), reverse positive (gas opening type), and reverse negative (gas closing type). The diaphragm pump formed by these four combinations has two modes of action: gas opening and gas closing. The selection of the operating mode of diaphragm pumps mainly considers three aspects: process production safety; Characteristics of the medium; Ensure product quality and minimize economic losses.

DBY Electric Diaphragm Pump Product Features

9. According to different media, the diaphragm is divided into chloroprene rubber, fluororubber, nitrile rubber, and tetrafluoroethylene, which can fully meet the needs of different users. The overcurrent components can also be divided into iron, stainless steel, and aluminum alloy according to user requirements, and the motor is divided into ordinary diaphragm pumps and explosion-proof diaphragm pumps.

Working principle of DBY electric diaphragm pump

Working principle diagram

The motor "4" drives the diaphragm "2" on the left and right plungers to move back and forth one by one through the gearbox "3". Inside the left and right pump chambers, there are upper and lower one-way ball valves "1" installed. The movement of the diaphragm causes a change in the volume of the working chamber, forcing the four one-way ball valves to open and close alternately, thereby continuously inhaling and discharging liquid.

Installation dimensions and external dimensions

DBY electricdiaphragm pumpPerformance specifications

1. Before installation, carefully check whether there are any hard objects inside the pump body to avoid damaging the impeller and pump body during operation.

2. During installation, pipeline management should not be added to the pump to prevent deformation and affect normal operation.

3. Tighten the anchor bolts to prevent vibration during start-up from affecting the performance of the pump.

4. Install regulating valves on the inlet and outlet pipelines of the pump, and install pressure gauges near the pump outlet to control the pump's operation within rated conditions and ensure its normal use.
