Embodiment Construction

[0034] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but are not intended to limit the protection scope of the present invention.

[0035] This embodiment provides a specially designed grouting pump for snow-melting composite pipes on runways.

[0036] Due to the design requirement of the pump is small flow, high head, and the fluid has the physical characteristics of high viscosity and high density, it is selected as a positive displacement reciprocating pump. Positive displacement reciprocating pumps use the periodic volume changes in the working chamber to transport fluids. They are suitable for transporting various media with small flow rates and high lifts, such as high-viscosity, corrosive, flammable and explosive liquids. Conforms to the fluid (slurry) transport characteristics.

[0037] In order to adapt to the above characteristics, the axial plunger pump is selected, that is, the plunge...

Abstract

The invention provides a grouting pump for a runway snow-melting composite pipe and a working method of the grouting pump. The grouting pump is suitable for small flow and high lift, fluid has the characteristics of high viscosity and high density, the grouting pump for the runway snow-melting composite pipe is a positive displacement reciprocating pump, the fluid is conveyed through periodic changes of the volume in a working cavity, the grouting pump is suitable for conveying various media with small flow and high lift, and the various media conform to this fluid (slurry) transport characteristic. The grouting pump is an axial plunger pump, that is, a plunger is arranged parallel to the axis of a cylinder body, and particularly relates to a swash plate type axial plunger pump which comprises the plunger (1), the cylinder body (2), a valve plate (3), a transmission shaft (4), a swash plate (5), a sliding shoe (6), a return plate (7) and a central spring (8). The working method of thegrouting pump for the runway snow-melting composite pipe is characterized in that the plunger cavity is in communication with an oil discharging window of the valve plate, oil is discharged through the oil discharging window, and the oil discharging process is formed; every time the cylinder body rotates by one circle, each plunger has a half-cycle oil suction function and a half-cycle oil discharge function; and if the cylinder body continuously rotates, the pump continuously sucks and discharges oil.

Description

technical field [0001] The invention relates to the technical field of public buildings and industrial buildings, in particular to a grouting pump for snow-melting composite pipes on runways and a working method thereof. Background technique [0002] Fluid heating snow melting technology refers to laying heat exchange pipes under the road to transfer and distribute external heat in the form of fluid, so as to realize the heat exchange and melting between the fluid and the snow on the road to ensure the normal use of the road surface. The heat exchange tubes buried under the pavement can not only melt the snow on the pavement through heat exchange, but also must not affect the structural force of the pavement and withstand the huge impact force of the aircraft when it lands. [0003] The fluid heating snow melting system uses a circulation pump to circulate the heated liquid in the pipeline buried inside the pavement, and the heat is transferred from the circulating medium to...
