This invention discloses a low-level protection device for a turbine lubricating oil tank, comprising a vent pipe, an oil suction pipe, and an oil outlet pipe. The vent pipe and the oil suction pipe are connected by an intermediate pipe. The upper opening of the vent pipe is higher than the maximum shutdown level, and the lower opening of the oil suction pipe is lower than the low-low level. The oil outlet pipe connects to the intermediate pipe and the oil suction pipe at the junction via a horizontal pipe with a perforated plate, forming a low-suction oil path. The oil outlet pipe extends horizontally out of the tank side plate. A horizontal pipe is connected at the junction of the vent pipe and the intermediate pipe, and the other end of the horizontal pipe connects to the oil outlet pipe via a downcomer, forming a high-suction oil path. The horizontal pipe is parallel to the horizontal pipe with a perforated plate. The highest point of the inner wall of the horizontal pipe is flush with the low level. The lowest point of the perforation in the horizontal pipe with a perforated plate is flush with the low-low level. This invention has a simple structure and effectively avoids rapid leakage of lubricating oil from the oil suction interface of the lubricating oil tank side plate, thus protecting the lubricating oil tank from low levels.

This invention discloses an automatically adjustable height mud pump support, relating to the field of mud pump technology. It includes a support base, a floating assembly, and a suction assembly. The floating assembly is located on the outer bottom of the support base and comprises a floating bucket, a partition layer, a connecting plate, a connecting pipe, and a water valve. The partition layer is connected to the inner middle of the floating bucket. This invention enables the mud pump to extract mud and wastewater. After extraction, the liquid level decreases. Because the equipment floats on the mud surface of the mud tank, it can lower along with the liquid level. During mud preparation and circulation, the equipment rises and falls with the liquid level. This ensures that the suction pipe remains below the mud surface during operation, eliminating the need for frequent height adjustments based on the wastewater level, greatly improving ease of use.

The present application relates to the technical field of water heaters, and discloses a control method of a gas water heater and the gas water heater. The gas water heater comprises a main heat exchanger, a condensing heat exchanger, a water inlet main pipe and an atomizer. The condensing heat exchanger has a water collecting cavity for collecting condensed water. The atomizer is used for atomizing the condensed water. The water inlet main pipe, the condensing heat exchanger and the main heat exchanger are sequentially communicated to form a water inlet waterway. When the real-time liquid level of the condensed water is greater than a preset liquid level threshold, the output load of the burner in the main heat exchanger is reduced. In this way, the gas water heater can reduce the generation amount of the condensed water when the condensing heat exchanger keeps working, reduce the situation that the condensed water liquid level reaches a dangerous liquid level, reduce the risk that the condensed water liquid level reaches the dangerous liquid level and triggers the shutdown of the gas water heater. Compared with stopping the work of the condensing heat exchanger to prevent the condensed water liquid level from rising, the condensing heat exchanger does not need to stop working and can continuously recover the heat in the high-temperature flue gas, so that the decline range of the thermal efficiency of the gas water heater can be reduced.
