The invention relates to an earth working machine and to a method for wear-optimized operation of such an earth working machine. Provision is made in this context that machine parameters with which the earth working machine is operated are adapted, in consideration of material properties of the substrate to be worked, in such a way that favorable wear behavior exists for the earth working tools being used.

A component of a gas injection system (tuyere / tymp) removal apparatus comprising a pneumatic or hydraulic hammer reverse mounted into a hammer frame, the working end of the hammer fixedly attached a first end of a slidable frame. The slidable frame having a second end fixedly attached to an elongated lifting arm means with a component handling means, and two sides slidably attached to the hammer frame. The component handling means may be inserted into the rear of a component of a gas injection system. When activated, the hammer generates a pulling motion on the component handling means engaged with the component of a gas injection system, releasing the component of a gas injection system from the wall of the blast furnace.

The invention provides a pressure relief device. The pressure relief device comprises a sealing valve, a blasting needle, a valve rod mechanism, a power mechanism and a compression bar mechanism; thevalve rod mechanism bears the pressure of the inlet end of the sealing valve and axially extrudes the blasting needle; the power mechanism is connected to the sealing valve and has a tendency to openthe sealing valve; when the blasting needle is stable, the valve rod mechanism is not triggered, levers of the compression bar mechanism are limited, the levers limit baffles so as to lock the power mechanism in a state that the sealing valve is closed; when the pressure exceeds a set pressure value, the blasting needle is unstable, when the valve rod mechanism is triggered, the levers do not limit the baffles, so that the levers lose the limiting effect on the power mechanism, and the power mechanism drives the sealing valve to be opened for pressure relief. According to the pressure relief device, the pressure relief precision is high, debris is not generated in the pressure relief process, the maintenance cost is avoided, reset is simple, and the shutdown cost is low; and in addition, the levers and the baffles are coordinated with the action of a control lever, so that the influence of the friction force can be reduced, and therefore the pressure relief device can be more sensitivein response.

A sensor device having a first housing with a first semiconductor body and a plurality of metallic terminal contacts for electrical contacting of a first sensor, and a second housing with a second semiconductor body with a plurality of metallic terminal contacts for electrical contacting of a second sensor. A section of the plurality of terminal contacts penetrates the second housing on the face side and the second semiconductor body is arranged with a back surface on a front side of the second metal substrate. The two housings form a module, whereby the two housings are connected form-fittingly to one another in the shape of a stack by a fixing device in a way in which the bottom side of the first housing is joined to the bottom side of the second housing and the plurality of terminal contacts of the two housings point in the same direction.

An electrolytic bath sideliner on-line second line maintenance method relates to aluminium cell maintenance method. It includes 1, adjusting electrolyte aluminum liquid horizontal total height to 35-15cm; 2, adjusting bath voltage to 1.8-5.5 v; 3, keeping cell temperature at 850-1100 degree centigrade; 4, pressing one barrier layer between electrolyte and furnace side; 5, using pneumatic tools to clean electrolytic bath side covered material, electrolyte furnace side, residuary side liner material, depth reaching 20-45cm, whole side being cleaned; 6, laying single-layer carbonaceous paste on cleaned interface with thickness of 1-10cm; 7, using charcoal block or carborundum block laying side of carbonaceous paste; 8, recovering production according to managing method after starting up electrolytic bath. Said invented method can replace whole sideliner material without electrolytic bath stopping operation.

The invention discloses an automatic detecting oil cup and an automatic liquid level detecting method applying the automatic detecting oil cup. The automatic detecting oil cup comprises an oil storagetank body, a cover body, an oil guide device and an oil-fur separator, wherein a liquid level sensor is arranged on the cover body. According to the technical scheme adopted by the invention, the automatic detecting oil cup can realize real-time detection on a liquid level position in the oil cup, can emit an alarm signal while the liquid level is lower than a safe position, reminds a maintenancepersonnel to timely fill lubricating oil into the oil cup to achieve the purpose of grasping oil amount in the oil cup without stopping an elevator to maintain, reduces workload of the maintenance personnel and elevator stop cost of a user, and increases a work safety coefficient of the maintenance personnel.

The invention discloses a gear performance degradation evaluation method based on AR model and dictionary learning. First, use the autoregressive model (AR) to extract the characteristics of the non-faulty samples and the samples to be tested, and use the AR model coefficients of the non-faulty samples to construct an overcomplete dictionary model, and then input the AR model coefficients of the samples to be tested as feature vectors into the dictionary model Get the reconstructed AR model coefficients in . Finally, the autoregressive models are respectively constructed from the original AR model coefficients and the reconstructed AR model coefficients, and the time series modeling of the signal to be tested is completed respectively, and the root mean square error of the residual sequence obtained by the two autoregressive models is used as the performance degradation index The adaptive early warning threshold is set, and the experimental analysis shows that the evaluation index obtained by the performance degradation method proposed in this paper can monitor the performance degradation trend of the gear in real time and can detect the early failure of the gear in time.
