What are the important advantages of mechanical diaphragm metering pumps before mechanical diaphragm metering pumps? What are the characteristics of mechanical diaphragm metering pumps?

1 The purchase price is relatively low.

2 and no driving force tightness, it is not easy to cause the metering pump to leak liquid components.

3 And the mechanical diaphragm metering pump can also transmit a variety of chemicals with very high viscosity, which can transmit a variety of chemicals with corrosion and wear risk sources for chemical enterprises.

4 Mechanical diaphragm metering pump diaphragm bearing capacity is very high, diaphragm use period is not long, be sure to disassemble on time.

5 The inlet and outlet pressure of the mechanical diaphragm metering pump can exceed 2mpa or more, but the flow rate is relatively small compared with the standard, and the accurate measurement accuracy of the mechanical diaphragm metering pump can be guaranteed to be about 5%. When the pressure is from at least to a large process, the change in flow rate can be guaranteed by about 10%.

6 Mechanical diaphragm metering pump is the motor according to the direct transmission device to drive the rack for variable speed movement, under the action of the crank connecting rod mechanism, the rotating operation is transformed into a uniform linear fitness movement.

The guide rail is connected with the pulse damper immediately, and the arterial punch damper is pushed (pulled) and flaps back and forth when the guide rail is constantly exercising in the work. The purpose of suction and discharge is completed according to the opening and closing action of the unidirectional throttle valve on the pump to ensure the efficacy of delivering the liquid medicine.

7 is the machine that can measure and detect the delivery of liquid medicine, also called variable plunger pump, occupancy pump. Generally described as: mechanical diaphragm metering pump is a type of pump that can take into account a variety of demanding production processes, and the flow rate can be stepless adjusted in the range of 0-100% to transport liquids (especially etched liquids).

The electromagnetic drive metering pump has only one prefabricated component for exercise and fitness - an electric parallel spool. In general, the lower the prefabricated components for sports and fitness, the more reliable the metering pump is in operation. Metering pump is especially suitable for low flow, low pressure work site, and in the power supply and distribution system flow change has excellent filling role.

What are the characteristics of a metering pump with a fixed four-stroke length and changing frequency compared with a metering pump with a fixed four-stroke length and changing frequency? According to the correction, the dosage of each four-stroke is known. Therefore, the total dosage can be calculated (dosage = dosage per four strokes * frequency).

The total dosage is linearly dependent on the frequency (50% frequency =50% dosage). Depending on the external pulse or analog input input control, the dosage can be adjusted from low to high in less than one second. In addition, it is much lower than the four-stroke length adjustment cost of DC servo motors.
