On The Domestic Development Trend Of Fuel Injection Pump Test Bench (figure)

Table shows, by way of power transmission speed control method and the classification of domestic production factories are common test bed, mainly of drive slip clutch transmission and exchange of Frequency Control of two types of products. The production machinery, hydraulic speed test rig have a DC speed control of the two, and its yield is quite low, more than the total combined annual output of three types of products less than 1 million units.

2, Pump Test Control System Power Status

(1) mechanical rotation speed Test Mechanical rotation speed can be adjustable test rig is used to achieve the fuel pump drive pulley rotational speed of the CVT to persuade the. The type of test stand started in the late fifties in domestic production, because of its simple structure, easy production, maintenance in the industry account for a large fuel pump Market However, the low transmission efficiency of the type of product, speed narrow, difficult to meet the high-speed, high-power diesel engine fuel injection pump debugging, currently only a small amount of this type of test bed, mainly for tractors, construction machinery, diesel fuel injection pump of small and medium power debugging, these products are already out of product.

(2) Hydraulic Test Bench Hydraulic Transmission Test Bed, the transmission efficiency and speed stability, generally able to satisfy the requirements of various types of fuel injection pump debugging. Since the domestic production since the sixties, is a mechanical test bed replacements. Currently, fuel pump repair industry has a larger market.

As the product is driven hydraulic pump motor to make the drive shaft speed, and its processing of high precision hydraulic components, the structure is relatively complex, making manufacture more difficult to use in maintenance more difficult, the operation is not very convenient, voice loud. Therefore, the species present in the pump test rig manufacturers oil Tsui has been basically eliminated.

(3) slip-type test bench Slip differential test rig is the end of the seventies began mass production of products, manufacturers and maintenance of pumps Tsui industry has large holdings.

Base slip clutch test rig is normally provided by manufacturers to design products and matching with the ordinary three-phase asynchronous motor, there are some manufacturers directly with the professional manufacturers of electrical slip speed motor assembly on the test stand .

Main features of such a test stand is simple in structure, easy maintenance, use and convenient operation, high reliability, its performance can meet the pump oil Tsui production debugging and maintenance industries. But there are also unstable speed control performance, likely to cause defects such as speed control, the failure of the equipment maintenance and operations personnel have a certain degree of risk, for which individual manufacturers of the products in the measurement and control instrument part of the pre-installation of the speed Purchase protection, which effectively ensure the safety of equipment operation.

(4) variable frequency test sets VVVF is eighties was able to quickly Developing Electromechanical Automation. It is the application of microprocessor technology and high-power electronic components constitute the motor speed control system, the output drive shaft by the motor drive shaft directly to the general output, smooth operation, its torque characteristics such as fuel injection pump provides precise speed debugging, operation more convenient, and feature more perfect. Therefore, domestic fuel injection pump test stand manufacturer or patented production technology through the introduction of the product, or self-development and design, quickly develop a variety of specifications of variable frequency type fuel injection pump test bench, fuel injection pump test bench to the localization to be more technically greatly improved.

Order to improve the function, the kind of test bed is also generally added to improve power supply, gas supply, flow meters and other additional features.

3, Fuel Injection Pump Test Bench Measurement System Status

(1) speed computing, control instruments Pump fuel pump test bench debug speed measurement is the basic guarantee. Currently, almost all types of products are accompanied by digital display tachometer, tachometer pointer early period has already eliminated. Amount of oil also is the use of electronic counting counting device placed in counting, control the fuel pump debugging. In addition, manufacturers are also many other monitoring and control of product configuration features such as automatic digital control of oil temperature and oil pressure, air pressure (vacuum) of digital measurements. In short, the conditions necessary for fuel injection pump test parameters can be measured by the digital meter, so that test conditions, the control accuracy is improved greatly.

(2) fuel injection pump test debug parameters

Debugging parameters of fuel injection pump is the main fuel tank, the current test primarily to measure the main glass cylinder, but the biggest drawback of this measurement is the measurement process is slow, particularly in the oil pump is not suitable Tsui professional manufacturer of high-volume production, therefore, the new products developed in foreign countries, the use of computer monitoring and control technology and design Sensor The amount of the fuel injection pump for rapid, continuous measurement, is the urgent problem, which is made with advanced fuel injection pump test bench products where the gap between the real.

4, fuel injection pump test bench development trends and recommendations

(1) As the test rig is mainly used in oil Tsui pump manufacturers and maintenance debugging, and production volume of manufacturers, production is, therefore, it requires test bed is higher degree of automation, such as the fuel pump and fast fixture Rapid measurement of digital fuel injection quantity, etc.; and maintenance industry are required to be able to adapt to a variety of test bench debug fuel injection pump, with a more complete accessories.

(2) fuel injection pump test bench for future technology development should be focused on the full use of computer monitoring and control technologies, so that the conditions in the fuel injection pump commissioning and technical parameters in the completely automatic digitally measured to meet the fuel pump products increasing technology and quality needs.

Where is the ignition coil on my 98 ford contour?

It is the 2.0 zetec engine and i need to know where the ignition coil is so i can hook up a tachometer i'm about to buy. i don't have a manual and i'm only familiar with tractors and diesel engines. links to pics or videos would be great.

Jeez, those 2 must be really bored to post to questions where they don't have a clue as to the answer, huh?

Since your car has a distributor-less ignition, the spark plug wires connect directly to the coil pack. Basically 2 coils combined in one unit, that operate 2 cylinders each. Center terminal provides feed to both, and side terminals control each coil. My guess would be you would want to tie into the wire to the center terminal for the Tach, but you should check with the manufacturer for that and whether it's compatible with this type of coil first, just to be on the safe side. Try their website for installation instructions maybe.
