Description

Power station water leads oil groove and goes up oil level measuring device

Technical Field

The utility model relates to a water leads oil groove oil level and measures technical field, especially relates to a power station water leads oil groove and goes up oil level measuring device.

Background

In the prior art, a pressure type liquid level meter 2 is always used for analog quantity measurement and display in the oil level measurement of a water guide oil tank, and a float switch 3 is used for alarm of high and low limit switching quantities of an oil level, as shown in figure 1. During use, there are two problems:

1. the oil level on the water guide oil tank is influenced by fluctuation, the pressure at the bottom of the oil tank changes, and the pressure type liquid level meter reflects liquid level change according to the pressure change, so that the measured and displayed data always have the phenomena of fluctuation and jump, the monitoring of the actual oil level of the water guide oil tank of the unit by operators is influenced, and the safe and stable operation of the unit is not facilitated.

2. The floating ball switch is slightly interfered by oil level fluctuation due to the fact that the floating ball is large, but the floating ball is large, and therefore the error is large when the alarm fixed value is set to be high and low. Because the setting constant value must be set in a shutdown state (the float switch cannot be detached for setting in the running of the unit), the actual constant value must be determined whether the setting condition is accurate or not only when the oil level reaches a high alarm oil level or a low alarm oil level in the running process, but also when the unit hardly reaches the high and low alarm oil levels in the normal running process, the float switch has the condition of false alarm or no alarm caused by the difficulty in setting in the use process.

Therefore, it is necessary to develop a device for measuring the oil level on the water-guiding oil tank of a hydropower station to solve the above problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that a hydropower station water guide oil groove oil level measuring device is designed.

The utility model discloses a following technical scheme realizes above-mentioned purpose:

a power station water leads oil groove oil level measuring device includes:

Furthermore, the wave-proof pipes are all perpendicular to the inner top wall of the water oil guide groove.

The beneficial effects of the utility model reside in that:

the floating ball liquid level meter is slightly influenced by the fluctuation of the oil level due to the larger floating ball, and is basically not influenced by the fluctuation of the oil level after the wave-proof tube is additionally arranged, so that the measurement and display numerical value is accurate, and the phenomena of fluctuation and jumping are avoided.

The digital display meter collects the analog quantity output of an added floating ball liquid level meter, and then sets the limit values of high and low switching values to send an alarm; the digital display meter can set the oil level switching value when the unit operates, and the setting fixed value is visual, convenient, accurate and reliable.

The added digital display has the function of on-site display, and field patrolmen can conveniently and intuitively master the actual oil level of the water guide oil tank.
