Abstract
Provided is a high-pressure pump rear cover capable of improving the heat dissipation performance. The high-pressure pump rear cover capable of improving the heat dissipation performance comprises a cover body and a liquid flowing path, wherein the middle of the cover body is formed by protruding outwards, a water inlet is formed in one side of the upper end face of the protrusive portion, a water outlet is formed in the other side of the upper end face of the protrusive portion, and a water drain hole is formed in the lower end face of the protrusive portion; the liquid flowing path is a hollow pipeline of a grid-shaped structure and is installed inside the middle of the cover body, a water inlet is formed in one side of the upper end, a water outlet is formed in the other side of the upper end, and a water drain hole is formed in the lower end. According to the high-pressure pump rear cover capable of improving the heat dissipation performance, the hollow pipeline of the grid-shaped structure is arranged inside the cover body to serve as the liquid flowing path, and meanwhile high-temperature lubricating oil inside a crankcase is forcibly cooled through multi-path cooling water, the contact area between the water and the hot oil is increased, and heat exchange efficiency is improved. Due to the large heat dissipation area, the cooling capacity is improved greatly, the service life of each component inside the crankcase can be prolonged, and production cost is lowered.
Description
Technical field
The utility model belongs to hydraulic machinery technical field, particularly relates to a kind of high-pressure service pump bonnet that can improve heat dispersion.
Background technique
High-pressure service pump is that a kind of high-pressure rotary-spray cement slurry that is used to provides high voltage power, for New Buildings, expressway, high-speed railway, the soft foundation strengthening reinforcement and strengthenings such as subterranean railway, old differential settlement of buildings regulation, reservoir dam and subsurface building works seepage proof curtain, gear earth cofferdam, mine leak stopping, well bucket retaining wall, the aspects such as slope anchorage, high-pressure service pump also can be used in high pressure water and take the photograph stream auxiliary rock coal breakage, underground hydraulic pressure pillar feed flow, underground large-scale pipeline dredging desilting is cleaned, high pressure water jet perforation or other fields that need to be power with highly pressurised liquid, mainly by power end and fluid end two-part, formed, power end is for passing to fluid end by the energy of prime mover, fluid end is for being converted to fluid pressure energy by mechanical energy, wherein power end mainly comprises crankcase and the high speed shaft, bent axle, gear ring, connecting rod and the crosshead that are arranged on crankcase inside, crankcase is comprised of casing and the bonnet that is arranged on casing upper shed place conventionally, and crankcase inside fills lubricant oil.But, there is following point in the high-pressure service pump of this structure: in high-pressure service pump running, high speed shaft, bent axle all need ceaselessly high speed rotating, therefore the contacting point of the parts such as itself and gear ring, bearing shell will produce a large amount of heats because of friction, this heat will pass to lubricant oil, makes thus the temperature of lubricant oil raise.As everyone knows, once oil temperature is too high, must affect the life-span of each parts in crankcase, thereby cause cost of production to raise, therefore need to lower the temperature in time to these parts.Because current conventional high-pressure service pump bonnet is the square iron plate of a block length, although that this bonnet has is simple in structure, easy processing, low cost and other advantages, shortcoming is that heat dispersion is bad.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of high-pressure service pump bonnet that can improve heat dispersion of reasonable in design.
In order to achieve the above object, the high-pressure service pump bonnet that can improve heat dispersion that the utility model provides comprises main body and liquid flow passageway; Wherein outside outstanding formation the in the middle part of main body, and upper-end surface one side at outstanding position is formed with a plurality of water inlets, and opposite side is formed with a plurality of osculums, is formed with a weep hole on lower end surface; Liquid flow passageway is the hollow pipeline that is fenestral fabric, the middle part that is arranged on main body is inner, upper end one side be provided with a plurality of respectively with water intake that in aforementioned body, a plurality of water inlets are connected, opposite side be provided with a plurality of respectively with the water outlet that in aforementioned body, a plurality of osculums are connected, lower end is provided with the drain opening that in an aforementioned body, weep hole is connected.
The cross section of described liquid flow passageway is square, rectangular or circle.
Described liquid flow passageway is to inner outstanding formation of crankcase, to increase contact deep fat area.
The high-pressure service pump bonnet that can improve heat dispersion that the utility model provides be in its body interior setting, be fenestral fabric hollow pipeline as liquid flow passageway, utilize multichannel cooling water to force to carry out cooling to the high temperature grease in crankcase simultaneously, area of contact with increase with deep fat, improves exchange heat rate.Because heat diffusion area is large, therefore can greatly improve cooling capacity, so can extend the working life of each parts in crankcase, reduce production costs.
