Analysis of Micro Piston Pump Technology

1. Working principle

The working principle of the mini piston pump is based on the reciprocating motion of the piston in the cylinder to generate pressure and thereby deliver fluid. The reciprocating motion of the piston is achieved by a crankshaft connecting rod mechanism, which converts rotational motion into linear motion. When the piston is pushed forward in the cylinder, fluid is sucked into the pump; when the piston moves backward, fluid is discharged out of the pump.

2. Main components

The main components of the dc piston pump include:

1. Piston: The piston reciprocates in the cylinder and is the main component that generates pressure.

2. Cylinder: The cylinder is the component that holds the piston, and there is corresponding lubricating oil inside to reduce friction.

3. Crankshaft connecting rod mechanism: The crankshaft connecting rod mechanism converts the rotational motion of the motor into the reciprocating motion of the piston.

4. Pump head: The pump head is the channel for fluid to enter and exit, and is usually equipped with a filter to prevent impurities from entering.

5. Motor: The motor powers the miniature piston pump, usually a DC motor or a stepper motor.

3. Performance characteristics

Micro piston pumps have the following performance characteristics:

1. High pressure output: Due to the reciprocating motion of the piston, the reciprocating piston pump is able to generate high outlet pressure.

2. Adjustable flow rate: By changing the speed of the motor, the reciprocating speed of the piston can be adjusted, thereby adjusting the flow rate.

3. Good controllability: Due to the precise control of the motor, the micro piston pump has good flow control accuracy.

4. Compact and lightweight: The micro piston pump is small in size and light in weight, making it easy to carry and use.

5. Widely used in various fluids: suitable for transporting various fluids, such as gases, liquids, etc.

4. Application fields

Micro piston pumps have a wide range of applications. The following are some typical application areas:

1. Medical field: used to transport medicinal liquids, blood, etc.

2. Laboratory field: used to conduct various fluid experiments, such as fluid dynamics experiments, etc.

3. Industrial field: used in various situations where fluid needs to be transported, such as gas compression, liquid pressurization, etc.

4. Other fields: such as gas cylinder pressure testing, fuel delivery, etc.

5. Development Trend

With the advancement of science and technology and the expansion of applications, the development trends of micro piston pumps are as follows:

1. High precision: In order to meet more precise control needs, the flow and pressure control accuracy of micro piston pumps will continue to improve.

2. Long life: Increase the service life of the micro piston pump, reduce maintenance costs and the frequency of component replacement.

3. Intelligentization: By integrating sensors and microcontrollers, intelligent control and management of micro piston pumps are realized, improving their automation and intelligence levels.

4. Diversification: According to the needs of different application fields, develop micro piston pumps with special properties and uses, such as corrosion resistance, high temperature resistance, explosion-proof and other special types.

5. Environmental protection and energy saving: Pay attention to the environmental protection and energy saving design of micro piston pumps, such as using high-efficiency motors and optimizing the pump body structure to reduce energy consumption and noise pollution.
