Abstract
The utility model relates to a special device, which can debug and detect the various performances of a fuel-injection pump. The utility model comprises a working bench, a measuring tank and fuel tank. The inner of the measuring tank is provided with a fuel injector and a fuel gathering drum. A motor which is controlled by a frequency converter is connected with a main shaft. The utility model uses the frequency converter to change the frequency of a power supply source to drive the motor, which makes the rotating speed of the motor have stepless adjustment in a large range, omits a rotation difference clutch, a leather belt and the driving mechanism of a gear, reduces driving power consumption and increases the control precision of therotating speed, so the measuring precision of fuel quality is enhanced, the low speed characteristic of the experimental bench is improved and the motor isn't idled. The utility model saves energy 40% compared with the existing products.
Description
The utility model relates to a kind of debugging, detects the special device of every performance of Injection Pump, i.e. diesel fuel injection pump tester.
The spindle speed precision of diesel fuel injection pump tester and count number olein degree are most important technical orders.In the existing product, 12PSD55/75 type fuel injection pump tester (structure as shown in Figure 1) as the manufacturing of smart peak, Hubei testing installation Co., Ltd, link by machine driven system and main shaft by Slipper motor, Slipper motor is controlled by a silicon controlled rectifier, regulates motor speed by the size of current of regulating field coil.The shortcoming of this mode is: 1, need speed differential clutch, belt and gear drive, make the device structure complexity, power consumption is big, and noise is big.2, the rotating speed control accuracy is not high, influences the oil measurement precision.3, low-speed characteristic is poor.
The purpose of this utility model provides a kind of driving mechanism, rotating speed control accuracy height and good diesel fuel injection pump tester of low-speed characteristic of reducing.
Scheme of the present utility model is: comprise worktable, masuring tank and fuel tank, establish oil sprayer and oil pooling cylinder in the masuring tank, linked by the motor and the main shaft of Frequency Converter Control.
Press such scheme, the oil pooling cylinder bottom is provided with weighing transducer, this weighing transducer links by transmitter and interface circuit and computer, temperature transducer that oil spout number of times input circlult is warm with surveying oil and interface circuit thereof and computer input end link, this computer is provided with output unit, and other has the may command oil baffle to open and close and the controller and the fanout of motor power link.
The utility model utilizes frequency variator change power supply frequency to come drive motor, make motor speed stepless adjustable on a large scale, the effect that produces is: 1, saved speed differential clutch, belt and gear drive, reduced the transmission power consumption, improved output power, reduce voice, improved reliability.2, improve the rotating speed control accuracy, thereby improved the oil measurement precision.3, greatly improved the low-speed characteristic of this test stand, made stability of rotation under the low speed, output torque increases.4, do not have the situation of motor idle running to take place, make this test stand than existing product energy-conservation 40%.
The computer that has the masuring tank of weighing transducer and link with it constitutes oil-measuring apparatus.Utilize weighing transducer as calculated machine handle to obtain measurement result, can improve measuring accuracy greatly, by Computer Processing, eliminate the error that temperature variation is brought by the oil temperature that records.Simultaneously, can measure automatically, its oiling, rush down oil, show that measurement result all can finish automatically, and can carry out single measurement a certain rotating speed that presets.This shows that this mode has improved manufacturing efficiency, has reduced labor strength.
