Description
Technical field
the utility model relates to slurry pump, particularly the side cover of slurry pump.
Background technique
slurry pump is to the machinery of the washing solution such as slurry conveyed or water in boring in drilling process, is the important component part of drilling equipment.Conventional slurry pump is piston type or plunger type, and driven the crank up of pump by power engine, bent axle drives piston or plunger to move reciprocatingly in pumping cylinder by crosshead again; Suck and expulsion valve alternating action under, realize the object of force feed and circulating flushing washing lotion.
in use, easily there is burnout phenomenon in its centering guide and crosshead with slurry pump.Because of the restriction in time and place, the inspection method using working platform scene to accomplish is difficult to the body reason finding to produce fault usually, and often need slurry pump to carry out large repairs inspection comprehensively.Will cause comprehensive stopping production like this, this is obviously that work unit institute is unacceptable.Therefore, need platform operations personnel to strengthen observation to slurry pump runnability and detection at ordinary times, Accident prevention is magnified, by accident control in bud.
for above-mentioned problem, people have appreciated and have not known, and in addition improvement, a kind of slurry pump side cover with visor [application number: 201020283340.7 disclosed in Chinese patent storehouse; Authorization Notice No.: CN 201779008 U], side cover is provided with visor, and visor and slurry pump side cover are by flange or be threaded.Slurry pump side cover is provided with visor hole, and visor comprises visor seat, endoscopy glass, sealing gasket and flange plate; Visor seat is positioned at slurry pump side cover outer surface and welds with the edge in visor hole; The end face of visor seat is provided with bolt hole, and visor seat is provided with sealing gasket, endoscopy glass, sealing gasket and flange plate successively, and flange plate is connected with visor seat by bolt.
the above-mentioned slurry pump side cover with visor observes the runnability of slurry pump inside in use by endoscopy glass; But there is following problem in this slurry pump side cover: endoscopy glass is offseted with visor seat and flange plate respectively by its both sides and is fixed, but this means of fixation easily causes sealing gasket or endoscopy glass displacement when assembling, make the position readjusting sealing gasket and endoscopy glass again, cause assembling comparatively loaded down with trivial details, simultaneously also comparatively strict to the size requirement of each component.
Summary of the invention
the purpose of this utility model there are the problems referred to above for existing technology, proposes a kind of side cover of slurry pump easy to assembly.
the purpose of this utility model realizes by following technical proposal: the side cover of slurry pump, comprise side cover body, it is characterized in that, described side cover body outer side wall has protrusion and tubular connecting cylinder, described connecting cylinder and side cover body are made of one piece by same material, inside described connecting cylinder, there is ring-shaped step, the access panel be made up of clear glass is provided with in described ring-shaped step, sealing gasket is in the form of a ring provided with between described access panel and ring-shaped step diapire, tubular location cylinder is plugged with and the inner and described access panel of this location cylinder offsets in described ring-shaped step, ring-shaped step is stretched out in described location cylinder outer end, described location cylinder outer end has annular shoulder block, and described annular shoulder block is connected mutually by some screws and described connecting cylinder.
