With the rapid development of society, all walks of life are increasingly demanding products. In the production of modern steel and other materials, up to 80% of the processes need to go through fine plastic processing. Therefore, many manufacturers have insight into the opportunities, have poured into the field of automotive tube processing equipment processing and production, trying to get a share of this huge market. However, there are still challenges in the production of automotive tube processing equipment.

In the production process of automotive tube processing equipment, the speed control circuit is very important. There are two main types commonly used by manufacturers: variable pressure throttle speed control circuit and positive displacement speed control circuit. Among them, the variable pressure throttling speed control loop realizes the accurate control of speed by adjusting the flow area of the flow control component in the loop. However, the working pressure in this way is not static, but fluctuates as the load changes. The throttle valve controls the inflow flow of the hydraulic cylinder by cleverly adjusting the flow of the tank.

However, the variable pressure throttling speed control circuit is not perfect. Due to the soft mechanical characteristics of automotive tube processing equipment, the piston may stop moving when the load increases to a certain extent. Therefore, this method is more suitable for use in the case of high speed and small load change.

The positive displacement speed control loop is to adjust the speed of movement by adjusting the displacement of the variable pump or motor in the loop. This method has high efficiency and low heat generation, because the oil output from the hydraulic pump will flow directly into the executive assembly, avoiding the loss of overflow and throttling.

In the production process of automotive tube processing equipment, it is very important to choose a suitable speed control circuit.
