When the laser sensor is working, the laser emitting diode is first aimed at the target to emit laser pulses. After being reflected by the target, the laser scatters in all directions. Part of the scattered light returns to the sensor receiver and is imaged onto the avalanche photodiode after being received by the optical system. Avalanche photodiode is an optical sensor with amplification function inside, so it can detect extremely weak light signals and convert them into corresponding electrical signals.
By utilizing the high directionality, monochromaticity, and brightness of lasers, non-contact long-distance measurement can be achieved. Laser sensors are commonly used for measuring physical quantities such as length (ZLS Px), distance (LDM4x), vibration (ZLDS10X), velocity (LDM30x), and orientation. They can also be used for non-destructive testing and monitoring of atmospheric pollutants.PARKER plunger pump PV046R1 factory stock in stock
During operation, the cam on the camshaft of the fuel injection pump and the plunger spring force the plunger to reciprocate up and down, thereby completing the pumping task. The pumping process can be divided into the following three stages. Conclusion: Based on the above discussion, the following conclusion can be drawn: ① The total stroke L of the reciprocating motion of the plunger is constant and determined by the lift of the cam. ② The fuel supply amount per cycle of the plunger depends on the fuel supply stroke, which is variable and not controlled by the camshaft. ③ The start time of fuel supply does not change with the variation of fuel supply stroke. ④ Rotating the plunger can change the end time of fuel supply, thereby altering the fuel supply amount. 3. Domestic series plunger fuel injection pumps. The domestic series plunger pumps mainly include A, B, P, Z, and I, II, III series. Serification is based on the different requirements for fuel supply in the single cylinder power range of diesel engines, using plunger stroke, pump cylinder center distance, and structural type as the basis, and then matching with different sizes of plunger diameters to form several types of fuel injection pumps with varying fuel supply in one working cycle, in order to meet the needs of various diesel engines. The working principle and structural type of domestic series fuel injection pumps are basically the same. Taking Type A pump as an example, this article introduces the structure and working principle of plunger fuel injection pumps. A plunger pump consists of four main parts: a sub pump, an oil quantity adjustment mechanism, a transmission mechanism, and a pump body
The plunger supplies oil upwards. When the inclined groove (stop supply edge) on the plunger is connected to the return hole on the sleeve, the low-pressure oil circuit in the pump chamber communicates with the middle hole, radial hole, and inclined groove of the plunger head. The oil pressure suddenly drops, and the oil outlet valve quickly closes under the action of the spring force, stopping the oil supply. Afterwards, the plunger will continue to move upwards. When the protruding part of the cam rotates past, under the action of the spring, the plunger will move downwards again. At this point, the next cycle begins. A plunger pump is introduced based on the principle of a plunger. There are two one-way valves on a plunger pump, and the directions are opposite. When the plunger moves in one direction, negative pressure appears in the cylinder. At this time, one one-way valve opens and the liquid is sucked into the cylinder. When the plunger moves in the other direction, the liquid is compressed and the other one-way valve is opened, and the liquid sucked into the cylinder is discharged. This working mode forms continuous fuel supply after continuous movement.
Usually, damage to high-temperature melt pressure sensors is caused by improper installation positions. If the sensor is forcibly installed in a small or irregularly shaped hole, it may cause damage to the sensor's diaphragm due to impact. Choosing a suitable tool to process the installation hole is beneficial for controlling the size of the installation hole. In addition, appropriate installation torque is beneficial for forming a good seal. However, if the installation torque is too high, it is easy to cause the high-temperature melt pressure sensor to slip off. To prevent this phenomenon, anti stripping compounds are usually applied to the threaded part of the sensor before installation.
