Embodiment Construction
[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0022] Please also refer to figure 1 , the explosion-proof device for the slurry pump provided by the present invention will now be described. The explosion-proof device of the slurry pump includes a pressure relief chamber, a wear-resistant ring 11, an oil outlet pipe 2, and a pressure relief pipe 4. The pressure relief chamber is arranged in the slurry pump and communicates with the pump chamber of the slurry pump; the pressure relief chamber The inside is filled with oil 6; the wear-resistant ring 11 is used to block the oil 6 from entering the pump chamber, an...

The invention provides an explosion-proof device for a slurry pump, and belongs to the technical field of slurry pumps. The explosion-proof device comprises a pressure relief cavity, a wear-resistantring, an oil outlet pipe and a pressure relief pipe, wherein the pressure relief cavity is arranged in the slurry pump, communicates with a pump cavity of the slurry pump and is filled with oil; the wear-resistant ring is used for stopping the oil from entering the pump cavity, can move to two sides by means of the pressure difference between two sides, and is blocked at a preset position when moving to one side of the slurry pump; the oil outlet pipe is connected with the pressure relief cavity, and a switching valve is arranged on the oil outlet pipe; and the pressure relief pipe is connected with the oil outlet pipe, a pressure relief valve is arranged on the pressure relief pipe, and the communication position between the pressure relief pipe and the oil outlet pipe is located betweenthe switching valve and the slurry pump. According to the explosion-proof device for the slurry pump, when the slurry pump is blocked, pressure can be released smoothly and an alarm can be given, andslurry does not flow into the oil outlet pipe, so that blockage of the oil outlet pipe by the slurry is avoided, sensitivity of the device is ensured, and the service life of the device is prolonged.
Description
technical field [0001] The invention belongs to the technical field of slurry pumps, and more specifically relates to an explosion-proof device for slurry pumps. Background technique [0002] A slurry pump refers to a machine that increases the energy of a solid-liquid mixed medium through the action of centrifugal force (rotation of the impeller of the pump), and converts electrical energy into kinetic energy and potential energy of the medium. Mainly applicable to: mines, power plants, dredging, metallurgy, chemicals, building materials and petroleum industries. During the use of the slurry pump, the inlet and outlet may be blocked. If the pressure is not released in time, energy will accumulate in the pump chamber, which may easily cause damage to the pump, explosion, pipeline collapse and other accidents. Contents of the invention [0003] The purpose of the present invention is to provide an explosion-proof device for a slurry pump, which aims to solve the problem th...
