Introduction to the oil pressure gauge commonly used in diesel generator sets
July 05, 2022
Oil pressure is an important indicator of diesel generator lubrication system, its size marks the strength of lubrication, generally use the oil pressure gauge to show the oil pressure situation situation, the oil pressure gauge is used to monitor the oil pressure in the main oil channel of diesel generators, diesel generator oil pressure is usually in the range of 0.15~0.3MPa.
Oil pressure is an important indicator of the diesel generator set lubrication system, its size marks the strength of lubrication, generally use the oil pressure gauge to show the oil pressure situation, the oil pressure gauge is used to monitor the oil pressure in the main oil passage of diesel generators, diesel generator oil pressure is usually in the range of 0.15 ~ 0.3MPa, this top Bo power to introduce you to the diesel generator set commonly used Oil pressure gauge.
1. Elastic tube type oil pressure gauge
Elastic tube type oil pressure gauge is mainly composed of a bent, oval cross-sectional brass elastic tube and gauge head. One end of the elastic flat tube (also called expansion tube) is connected to the lubricating oil channel through the oil pipe, and the other end is closed and connected to the sector gear through the connecting rod. The shaft is equipped with a pointer and gear, and the gear engages with the sector gear.
After the diesel generator starts, when the oil pressure in the oil channel gradually rises, the oil will enter the elastic flat tube, so that the elastic flat tube to the direction of straight deformation, then the fan gear is driven by the connecting rod to turn in the counterclockwise direction, so the gear will drive the pointer to turn in the clockwise direction, so that the pointer points to the higher oil pressure scale; when the oil pressure in the oil channel decreases, the elastic flat tube inward, through the connecting rod, fan gear, so that the gear and the pointer in the counterclockwise direction. Make the gear and the pointer turn in the counterclockwise direction, so the pointer points to the scale of lower oil pressure. When the internal combustion engine stops working, the pressure in the elastic tube disappears and the pointer returns to zero.
2. Electric heating type oil pressure gauge
Electric heating oil pressure gauge is the use of oil pressure changes to control the size of the current, and then use the thermal effect of the current, so that the bimetal deformation, push the pointer swing, so as to measure the value of the sleeve pressure. Electrothermal oil pressure gauge consists of two parts: sensor and indicator gauge, the sensor is connected to the main oil channel of diesel engine, and the indicator gauge is installed on the instrument panel, and they are connected by wires in the middle.
The elastic tube type oil pressure gauge is direct acting type, its pressure measurement sensitivity is high, but monitoring is not convenient, while the electric heating type oil pressure gauge is a non-electricity testing, power transmission and mechanical display instrument, it consists of oil pressure sensor, oil pressure gauge and information transmission wire, at present the electric heating type oil pressure gauge is widely used in power machinery.
