Description
Technical field
The utility model relates to oblique in pump crankcase technical field more particularly to a kind of burning into sand pressure break pump crankcase and crankshaft
Hole processing clamp.
Background technique
At home and abroad the fields such as each elephant, mine, chemical industry, electric power have and widely apply reciprocating pump.Reciprocal
The power end of pump, all movement vice division chiefs for having relative rotation and opposite sliding, is both needed to be lubricated, especially when transmitted plunger force
Greatly, when power is big, pump speed is high, force feed should also be used.Not only applying working condition is complicated for burning into sand fracturing pump, and changes in pump speed
Greatly, transmitting changed power is big.Therefore for crankshaft as the main part of burning into sand power end of fracturing pump, the lubrication of crank throw and bearing shell is necessary
Using force feed, power end friction lubricating just can guarantee in place, can be only achieved pump and normally, reliably run, this requires
Crankshaft oil hole not only wants unimpeded, moreover, cannot have the dead angle of easy deposited stains, more to reduce the hole number on crankshaft as far as possible,
To reduce the influence because boring oilhole to its intensity to greatest extent.
It in order to reduce friction, abrasion, and cools down kinematic pair working surface, take away frictional heat, keep kinematic pair working surface
Between gap, prevent working surface overheat and cause to kill or burn to death, extend the service life of reciprocating pump, in the power of reciprocating pump
In end, all movement vice division chiefs for having relative rotation and opposite sliding are both needed to be lubricated.And crankshaft is in the power of burning into sand fracturing pump
Rotary motion is made at end, crank throw combine with connecting rod bearing shell between form that friction is secondary, and lubricant passage way is necessary unblocked, therefore, crankshaft
The processing of upper each oilhole is just quite important.
Currently, the lubricant passage way oilhole on the widely used power end crankshaft of reciprocating pump hangs down on crank and crank throw both at home and abroad
Straight perforation, the processing of oilhole, the disadvantages are as follows: oilhole is more, are processed number using directly in the technique of radial drilling machine drilling
Tired, in a crisscross manner, machining deviation is larger, must again block in extra hole with silk plug after each machining of oil hole, and if oilhole processing
It is bad, easily stress is caused to be concentrated, to reduce crankshaft fatigue strength.Burning into sand fracturing pump bores oilhole pair to reduce to greatest extent
The influence of crankshaft strength, in design, each oil site oilhole of crankshaft is directly connected to, although this oil circuit is set by space inclined hole
Meter cleverly reduces the influence because boring oilhole to crankshaft strength very much, and oil circuit does not have dead zone, and oil excessively is more unimpeded, but with
Company's existing equipment and technique can not be drilled to the oilhole of design requirement, and processing technology is difficult.
