As people say: "Motor is the heart of the car." If the machine is driven by a diesel engine, then one part can rightfully be considered its core. This fuel pump is a high pressure fuel pump. If it fails, the motorist expects significant financial expenses. However, so that they do not increase, at the service station where the car is driven, there should be a stand for checking the fuel injection pump.
Most often, this element fails due to the use of low-quality diesel fuel. Small parts become clogged, soot forms on the nozzles. All this leads to loss of power, uneven operation of the diesel engine, which leads to the destruction of other car systems.
Without equipment such as a test bench for fuel injection pumps, you can’t count on quality repairs. The principle of its operation is simple - the pump is removed from the car and installed on a fixed platform, connected to the working bodies of the equipment - to the shaft and various probes with all pump elements. The installed asynchronous electric motor drives the pump through the shaft and displays it at different speed modes. And various kinds of sensors through the probes collect information about the technical parameters of the injection pump, which is then processed by the computing unit of the stand with subsequent display.
Repair of diesel fuel injection pumps is a rather complicated operation. And with the market value of parts, it is better not to save on the services of good specialists. Structurally, the high-pressure fuel pump is a rather complex combination of a large number of precisely fitted parts to each other. Moreover, most of them have gaps of a fraction of millimeters. Therefore, any service station, where they really work for quality, needs a stand for checking fuel injection pumps.
What data can be obtained using the stand? Firstly, determine with what frequency and under what pressure the fuel is supplied to the cylinders. Secondly, how evenly this happens. Thirdly, determine the frequency and angles of rotation of the injection pump shaft. We are talking about quantities that are so small that they are measured in fractions of the units that are familiar to us. As noted above, the computing unit processes the information and provides it in a form convenient for humans. Thus, the quality of diagnostics and repair is improved.
To verify the quality of the work performed, use a test bench for injection pump testing. Often the same stand is of a universal type - it can be used for both diagnostics and testing. Such a device is an indispensable tool for service stations aimed at providing quality services.
What conclusions can be drawn? The number of diesel engines installed on new cars in relation to gasoline is constantly growing. This means that the demand for quality repair services will increase. Having spent once on a good stand for checking fuel injection pumps of a universal type, you can significantly expand the volume and geography of your business. And this means increasing the overall profitability of the business and attracting new regular customers.
