燃油泵检测台 特征描述

此检测台是根据ATEX标准,为了研究汽车燃油泵的运作参数而建造的。检测件的环境条件:温度,压力和燃油量都能够被更改。

所有普遍的燃料类型和混合型都能够使用。电压,PWM(脉宽调制)信号频率,PWM信号振幅,PWM信号占空比这些参数都是可调节的。他们中的大多数也是可以通过参数编辑器进行控制。大量的传感信号被记录下来,并且存储在结果文件中。

也有一些信号以一个快速采样率记录下来。可检测的泵类型有,非控制DC泵,可控制DC泵,可控制EC泵,通过一个高精度功率测量器可实现电压,电流和功率的测量。

用于泵控制的PWM信号可由Sonplas公司研发的电子板而生成。检测流程的程序会在灵活性参数编辑器中制定。在制定检测流程时,此编辑器给操作者很大的自由操作空间。

Endurance GDI Pump Test Bench

This endurance test bench with two separate stations has been designed for different kinds of high-pressure gasoline injection pumps.
The test fuel and lubrication oil supply is fully integrated in the test bench. Temperatures and tank levels are continuously monitored. After editing the testplan in “SonDaSys-Flex Testplan”, it is possible to choose each station separately, as well as to start, stop and interrupt
each station. During the test, pressure, rotation speed, torque, temperature and flow are monitored and recorded.
The successful test is finished after a defined testing time. If an error occurs during the test, only the specific station will shut down and detailed information (analog values and information text) are stored. Thus, trouble shooting and diagnostics are easy to perform. For this reason a free configurable ring buffer is implemented, which stores the last minutes.
This information can be visualized.

GDI Pump Test Bench

The machine offers a fully automatic testing of cam-driven highpressure fuel pumps.
The mechanic drive and the low- and highpressure proof circuit are simulated by the test bench. The test devices are automatically supplied to the machine by a conveyor system. Inside the test bench a gripper handling is used for the transport of the pumps. There is also a camera for detection of the serial numbers of the pumps. The test is carried out in the
measurement station.
The automatic contacting of the test device inside the machine takes place on an easy changeable workpiece carrier. The changeover to a different pump type happens by changing this pump-specific workpiece carrier. Hereby, a high flexibility of the test bench to different geometries of the low-and high-pressure connector and to the electrical contacting of the test device is assured.
The test parameters are adjusted through a data based flexible test plan system.The individual test steps can be positioned in any order and number and with different set point limits.
By means of the central database on a separate server PC it is possible to easily connect several test benches of the same type. All results are automatically stored and archived on the server.
