DBY electric diaphragm pump

Diaphragm pump is separated from the live column and pump cylinder by a thin film, so as to protect the live column and pump cylinder. The part on the left side of the diaphragm in contact with the liquid is made of corrosion-resistant material or coated with a layer of corrosion-resistant material; The right side of the diaphragm is filled with water or oil.

Suitable for all kinds of highly toxic, flammable, volatile liquid, all kinds of strong acid, strong alkali, strong corrosive media, etc. It can transport particles up to 10mm in diameter, and has little wear to the pump when pumping mud and impurities. No need for irrigation, suction up to 7m, lift up to 50m. Through good performance, it can transport some medium that is not easy to flow, and has many advantages of self-priming pump, submersible pump, shield pump, mud pump and impurity pump. There are no rotating parts and no shaft seal diaphragm to completely separate the pumping medium from the moving parts of the pump and the working medium, and the conveyed medium will not leak outwards.

 

Electric diaphragm pump is a new type of pump, due to the breakthrough progress in the diaphragm material, to apply to petrochemical, ceramics, metallurgy and other industries, is characterized by no need for irrigation water, self-priming ability.

The motor drives the diaphragm on the left and right ends of the plunger through the reducer box to reciprocate. In the left and right two pump chambers, the movement of the upper and lower four one-way ball valve diaphragms causes a change in the volume of the working chamber, forcing the four one-way ball valves to open and close alternately, so that the liquid is constantly inhaled and discharged.

When choosing an electric diaphragm pump, the following aspects need to be considered:
The properties of the conveying medium: It is necessary to consider the corrosiveness, viscosity, density and other properties of the medium in order to choose the appropriate material and model.
Flow rate and head: It is necessary to select appropriate flow rate and head according to actual needs to ensure that the pump can meet production needs.
Power supply and voltage: It is necessary to consider whether the power supply and voltage meet the requirements to ensure that the pump can operate normally.
Model and brand: It is necessary to choose the appropriate model and brand based on actual needs to ensure the quality and service life of the pump.
Installation environment: It is necessary to consider whether the installation environment meets the requirements, such as temperature, humidity, explosion-proof level, etc.

1. Diaphragm pump device system:
The diaphragm pump equipment system is composed of one or more double-sided pumps, such as pneumatic double diaphragm pumps. The collection pipes on the water pump are separate, so that each side of the pump has a multi-component substance component. This device is connected to the outputs on both sides, so that the pump’s out of phase output is in phase. At each outlet of the pump, diaphragm isolation valves can be selected to prevent backflow of mixed materials. If a non 1:1 mixing ratio is required, an additional pump can be selected to achieve multiple mixing ratios.
Diaphragm failure monitoring system, used to detect leakage of diaphragm in diaphragm pumps. The system includes a pump and a diaphragm to isolate the studio from the pumping room. A first optical fiber is connected to the working chamber, and a pneumatic diaphragm pump is used to transmit an optical signal through the working fluid. A second optical fiber is connected to the studio to receive optical signals transmitted from the first optical fiber. The pump has a studio that contains working fluid; A pumping chamber, pneumatic diaphragm pump for pumping materials into and out of the pump; An electrical signal establishment device establishes the first electrical signal when the optical signal is transmitted from the first optical fiber and passes through the unpolluted working fluid to reach the second optical fiber. This electrical signal is set up by a device, which generates a second electrical signal when the optical signal is transmitted from the first optical fiber and the pneumatic diaphragm pump passes through the contaminated working fluid to reach the second optical fiber. When the second electrical signal is established, the leakage problem of contaminated materials entering the studio through the diaphragm can be detected.
2. Installation method for diaphragm pump inner membrane plate:
Under the condition of not affecting the volume change requirements of the pump, fully utilize the excellent compressive performance of the diaphragm, and install it on the geometric size of the diaphragm. It not only does not increase cost, but also greatly improves the service life of the diaphragm, ensuring normal production and improving product quality. It is suitable for the installation of diaphragms in various types of diaphragm pumps.
