Performance parameters of DBY electric diaphragm pumps

Electric diaphragm pump is a new type of pump, in recent years, due to the breakthrough progress made in the diaphragm material, to be used in petrochemical, ceramic, metallurgical and other industries, characterized by no irrigation and diversion, strong self-priming ability. The conveying medium and the transmission machinery are directly separated, so the medium will never leak outward. And the pump itself has no shaft liquid seal, and the service life is greatly extended.

Application field: Diaphragm pump in painting and ceramic industry has occupied an absolute dominant position; Environmental protection, wastewater treatment, construction, sewage, fine chemical industry is expanding its market share, and has an irreplaceable position with other pumps.

The DBY-10 electric diaphragm pump is driven by a cycloidal pinwheel reducer, and the double diaphragm is driven to reciprocate through the crankshaft slider mechanism, so that the volume of the working cavity of the bridge potato changes alternately, so as to achieve continuous inuckation and discharge of liquid. DBY-10 electric diaphragm pump can be used to absorb all kinds of corrosive liquids, liquids with particles, and liquids with high viscosity, volatile, flammable and highly toxic.

DBY-10 Electric Diaphragm Pump Applications:

1: Compact structure, small size, light weight, easy to assemble and disassemble.

2: High transmission efficiency.

3: Smooth operation and low noise.

4: Long service life.

5: It can be transported without leakage.

6: It can withstand no-load operation.

7: No need to irrigate water, can self-prime.

8: It has good performance through cracking, and large particles of impurities, mud, etc. can pass effortlessly.

9: According to different media, the coal in the diaphragm is neoprene, fluorine rubber, nitrile rubber, and tetrafluoroethylene, which can fully meet the needs of different users. The overflow parts can also be divided into stainless steel, rubber lining, aluminum alloy electrical, and the machine can be divided into ordinary type and explosion-proof type according to user requirements.

The selection and determination of the diaphragm pump caliber is mainly based on the flow capacity of the valve, i.e. CV. In the instrument design and selection of various projects, the CV calculation of the diaphragm pump should be carried out, and the design specification of the diaphragm pump should be provided. From the calculation of the CV of the diaphragm pump to the determination of the caliber of the valve, the following steps are generally required:

1. Determination of the calculated flow rate. The existing production capacity, the load of the equipment and the condition of the medium determine the calculation of the flow rate Qmax and Qmin

2. Determination of the pressure difference between the front and rear of the valve. According to the selected valve flow characteristics and system characteristics, the S (resistance coefficient) is selected, and then the differential pressure is determined and calculated.

3. Calculate CV. According to the adjusted medium, select the appropriate calculation formula and chart, and obtain cmax and cmin

4. Choose CV. According to Cmax, select Cmax and the closest level C. in the standard series of selected products

5. Diaphragm pump opening calculation. In general, an opening of 90% for the maximum calculated flow rate and 10% for the minimum calculated flow rate is required.

6. Verification of the actual adjustable ratio of the diaphragm pump. Generally requires a practical adjustable ratio of 10.

7. Determination of valve seat diameter and nominal diameter. After verifying the suitability, determine according to C.

The flow characteristics of the electric diaphragm pump refer to the relationship between the relative flow rate of the medium flowing through the valve and the displacement (the relative opening of the valve). There are only three commonly used ideal flow characteristics: straight line, equal percentage (logarithmic), and fast opening. The parabolic flow characteristics are between straight lines and equal percentages, which can generally be replaced by equal percentage characteristics, while the quick opening characteristics are mainly used in two-position adjustment and program control, so the selection of diaphragm pump characteristics is actually the choice of straight line and equal percentage flow characteristics.

The selection of the flow characteristics of an electric diaphragm pump can be calculated theoretically, but the methods and equations used are complex. Empirical guidelines should be adopted more and considered from the following aspects:

1. Analyze and select the adjustment quality from the adjustment system;

2. Consider the process piping;

3. Analyze the load change.
