What are the driving methods of the asphalt pump on the asphalt distributor?
December 4th,2020

Hydraulic Transmission

A hydraulically driven asphalt pump is a hydraulic pump that is directly driven by a diesel engine or powered by a gearbox. The hydraulic pump transfers kinetic energy to the hydraulic motor through hydraulic oil, and then the hydraulic motor drives the asphalt spreader. This method is often used for the entire vehicle of the asphalt distributor truck.

Advantages of using this hydraulic system to drive asphalt pumps for asphalt distributor pumps:

1. Small size and light weight;

2. High rigidity, high precision and fast response;

3. Wide range of speed regulation, various speed regulation methods;

4. Easy to realize safety protection.

Electric

The diesel generator is installed on the asphalt distributor. After generating electricity, it drives the motor, and then the motor drives the asphalt pump.

This drive mode is mainly used in small maintenance equipment, and has the characteristics of simple operation, variable frequency speed regulation skills, and large-scale speed regulation. However, when using electricity on mobile devices, you should pay attention to the safety of electricity. Prevent the occurrence of electric shock.

Direct drive of internal combustion engine

Choose gasoline engine or diesel engine to directly drive asphalt pump.

The internal combustion engine directly drives the asphalt pump, thereby preventing energy conversion and improving mechanical efficiency. However, the internal combustion engine has an idling problem, and the speed adjustment scale of the asphalt pump is affected to a certain extent.
