Description

Technical Field

[0001] The utility model relates to the technical field of emulsion pumps, in particular to a pneumatic double-liquid emulsion pump for mining. Background Art

[0002] The emulsion pump is used in the coal mining face to provide emulsion for the hydraulic support. The working principle is that the rotation of the crankshaft drives the piston to do reciprocating motion to achieve liquid suction and discharge. The hydraulic support is used to support the roof and provide a certain space for the coal mining machine to prevent the roof from collapsing. The emulsion is composed of 95% water and 5% oil. The hydraulic support is supported by the hydraulic cylinder to extend and retract. The emulsion pump is used in the coal mining face to provide emulsion for the hydraulic support. The working principle is that the rotation of the crankshaft drives the piston to do reciprocating motion to achieve liquid suction and discharge.

[0003] When using the existing emulsion pump, it is necessary to connect an external pipe to the suction pipe and the discharge pipe. Since the connection between the external pipe and the suction pipe and the discharge pipe is in a suspended state, the connection between the external pipe and the suction pipe and the discharge pipe is prone to loosening during use, thereby affecting the normal use of the emulsion pump.
