Description
Technical field
The utility model relates to shale gas drilling field, particularly one and is applicable to shale gas reciprocating type plunger fracturing pump housing.
Background technique
In shale gas fracturing work, all reciprocating pump will be used, such as fracturing pump.Pump case is to the bent axle in fracturing pump, and the first-class moving element of cross provides support the vitals with leading role.The fracturing pump that current oil field at home uses, having triplex pump also to have five cylinder pumps, is all that deceleration size is included, it is larger that this structure shines into pump case volume, and weld also more difficult, materials are also many, thus cause whole pump overweight, install on vehicle-mounted and cloth be set up neither be very convenient.Along with the exploitation of unconventional energy resource, corresponding fracturing technology also in raising, all need high pressure, huge discharge, reliable operation, and volume is little in supporting fracturing unit, is lightweightly convenient to vehicle-mounted reciprocating pump.So need to carry out innovative design to pump case.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of housing that can adapt to the Five-cylinder piston pump of the shale gas fracturing pump of shale gas fracturing work feature and exploitation feature.Make a kind of high-power, high pressure, huge discharge, small volume, the lightweight Five-cylinder piston pump design being convenient to the external shale gas pressure break of vehicle-mounted speed reducer become possibility, thus solve the some shortcomings of conventional five cylinder pump housings.
For solving the problems of the technologies described above, the utility model realizes as follows: a kind of novel shale gas fracturing pump pump case, comprise six blocks of side plates be arranged in parallel and do integrated support, six blocks of side plates are made up of four blocks of middle side plates and two pieces of outer panels being coated on side plate outsides in the middle of described four pieces, form an entirety with the vertically arranged end plate of side plate in one end of six blocks of side plates and plate-side plate welding; Five full circle steel bushings are welded with between six blocks of side plates; Described five full circle steel bushings and six blocks of side plates have the circular through hole of coaxial line with size in the Vertical direction of steel bushing axis; Every block side plate has crankshaft installed hole, each described crankshaft installed hole is welded with crankshaft bearing ring support, each described axis of crankshaft bearing ring support and the axes normal of steel bushing; Between two pieces of outer panels, be welded with upper and lower two pieces of circular arc plates, described upper and lower two pieces of circular arc plates rely on upper and lower eight pieces of stiffening plates and crankshaft bearing ring support to weld together; Be welded on the one end away from end plate with upper and lower two blocks of circular arc plate vertically arranged square flange plates and described two pieces of circular arc plates, described square flange plate has observation panel; At described two pieces of circular arc plates near end plate one end, the edge correspondence of upper and lower two pieces of circular arc plates is welded with upper and lower two cover plates, the other end and the two row tenons be up and down welded on end plate of described two cover plates weld together, described two cover plates is welded by ten pieces of middle stiffening plates with middle full circle steel bushing, and upper cover plate has a row peep hole.
Good effect of the present utility model is: applied widely, light being easy to of this device is installed; Also be beneficial to simultaneously and ensure machining accuracy and kinematic accuracy; Have employed concentrated swab case, be convenient to cycling and reutilization.
Accompanying drawing explanation
