Description

A kind of drilling pump material splashproof protective equipment
Technical field
The present invention relates to oil and natural gas drilling-production equipment field.Relate in particular to a kind of drilling pump material anti-splash device.
Background technique
Along with the development of oil-gas exploration, drilling depth progressively increases.This just requires the drilling pump performance need that represents drilling equipment core to obtain corresponding lifting.For example, drilling pump requires to have that drilling well power is large, weight is light and service life is long.
The wearing and tearing of depending on moving element of the service life height of drilling pump.For example, the wearing and tearing that caused by friction may occur in upper/lower positions: between (1) crankshaft and crank box; (2) between crankshaft and connecting rod; (3) between connecting rod and crosshead pin; (4) between crosshead pin and slideway.
In order to reduce the friction between these parts, drilling pump just need to use lubrication system.The lubrication system type using in different drilling pumps comprises pressure lubrication, splash lubrication etc.These lubrication systems adopt fluid lubricant, for example lubricant oil conventionally.Contribute to reduce the friction between each parts at drilling pump run duration at the mobile lubricant oil in the surface between moving element.
But, if lubricant oil has impurity, may produce adverse influence to the performance of lubrication system, for example, be present in the impurity meeting unstable wear in lubricant oil with granular, because these particles can inlay bur well pump moving element surfaces.
In lubrication system, the source of impurity comprises following one or more: (1) is before dress lubricant oil, because of drilling pump and the thorough impurity that is not retained in drilling pump and fuel tank groove the inside of oil tank cleaning; (2) metal granule producing by friction between moving element; (3) and the external particle that enter lubricant oil improper by splashproof control measure in drilling pump.
Can and before pouring lubricant oil into, clean inspection and eliminate by thorough cleaning drilling pump groove because cleaning the impurity problem thoroughly not causing, as for by fricative metal granule between moving element, the problem causing is little, or because these parts scribble hard metallic material by hard metal making conventionally.
The disclosure has solved because of the improper problem that causes foreign matter to enter lubricant oil of splashproof control measure, foreign matter may derive from water (cooling liquid of cooling drilling pump), drilling fluid (being usually used in the working medium in drilling pump), for example, when piston moves in cylinder sleeve, high-pressure slurry leaks between piston and cylinder sleeve, mix with cooling liquid simultaneously, subsequently, water and mud mix may pollution lubricating oil, thereby damage drilling pump.
The zones of different that existing anti-splash device is included in drilling pump is used guard shield.For example, at cylinder sleeve end, an anti-splash device is installed, or is pacified a backplate that diameter is larger in the middle of connecting rod.
But because of the design problem of existing slurry pump, existing anti-splash device can not stop water and mud contamination lubricant oil effectively.For example, current anti-splash device usually departs from cylinder sleeve in the time that drilling pump is worked, and in addition, current anti-splash device can not provide suitable fluid discharge, the liquid of fluid end will flow out from cylinder sleeve, flows to drilling well pump power end and pollute the lubricant oil of power end from inside.
In view of this, the disclosure has been improved the problems referred to above, provides a kind of and can stop foreign matter to enter lubricant oil and anti-splash device in the drilling pump of pollution lubricating oil.
