Screw compressor with explosion-proof liquid level controller

Abstract

The invention discloses a screw compressor with an explosion-proof liquid level controller. The screw compressor comprises a screw compressor body and a master controller thereof, a leaching-filtration type explosion-proof liquid level control mechanism is arranged in the screw compressor body, and the leaching-filtration type explosion-proof liquid level control mechanism comprises an electric control seat. According to the provided screw compressor with the explosion-proof liquid level controller, during work, the liquid level in the screw compressor body is monitored through cooperation among a floating ball, a magnetic block and a reed sensor, the liquid level of an oil storage barrel in the screw compressor is controlled through the liquid level controller, the master controller is triggered to stop under the explosion-proof requirement, and the explosion-proof effect is achieved; further, the outer side of a sliding rod is provided with a filter barrel, the filter barrel is uniformly provided with vertical filter grooves, the floating ball is sleeved with the filter barrel, through the arrangement of the filter barrel and the filter grooves, the hydraulic oil entering the filter barrel is filtered, and then the situation that impurities enter the sliding rod, so that the cooperation between the floating ball and the sliding rod is not smooth, the sensitivity is influenced, and then monitoring of the liquid level is not facilitated is avoided.

Description

technical field [0001] The invention relates to the technical field of screw compressors, in particular to a screw compressor with an explosion-proof liquid level controller. Background technique [0002] The screw air compressor adopts a pre-configured screw air compressor, which only needs a single power connection and its compressed air connection, and a built-in cooling system, which greatly simplifies the installation work. The screw air compressor is characterized by its high performance and high efficiency. , easy maintenance and high reliability and other advantages consistently provide high-quality compressed air for all walks of life; [0003] At present, the liquid level of the screw compressor is not directly controlled, and it is easy to cause the oil to be discharged from the system with the compressed air due to hydraulic pressure increase, oil failure or even damage, affecting or even polluting the external environment and hidden dangers of use. In addition, ...

Problems solved by technology

[0003] At present, the liquid level of the screw compressor is not directly controlled, and it is easy to cause the oil to be discharged from the system with the compressed air due to hydraulic pressure increase, oil failure or even damage, affecting or even polluting the external environment and hidden dangers of use. In addition, the traditional liquid level mirror is in the oil liquid. It only plays a role of liquid level observation. When the liquid level drops or the oil level leaks in a large area, it cannot play the role of warning or shutdown. However, the inventor proposed this screw compressor with an explosion-proof liquid level controller based on various factors. When the liquid level drops or the oil level leaks in a large area, the circuit can be cut off immediately to realize the shutdown alarm and avoid the increase of losses
