Abstract
The present invention relates to engineering equipment field, and in particular to a kind of reciprocal pump liner pressing device, including bolt, discharge fluid cylinder, cylinder sleeve flange, nut, studs, cylinder sleeve gland, gland locking plate, it is characterised in that：Studs includes two external thread sections；The cylinder sleeve gland includes two arc parts and two plane parts, and the gland locking plate includes two arc parts and two plane parts；Cylinder sleeve is positioned by cylinder sleeve flange, is pressed to by cylinder sleeve gland and studs and nut above discharge fluid cylinder, is controlled the moment of torsion of nut to compress cylinder sleeve, after compressing cylinder sleeve, is connected by screw bolts gland locking plate.Since the plane of cylinder sleeve gland and gland locking plate part is adjacent, cylinder spacing is reduced；Nut includes two internal thread segments and an outer-hexagonal part, is conducive to connect moment of torsion control；In this way, the size with regard to that can reduce reciprocating pump, improves job stability, alleviate weight, extend service life, having reached reduces cost, puies forward efficient purpose.
Description
Technical field
The present invention relates to engineering equipment field, and in particular to a kind of reciprocal pump liner pressing device.
Background technology
In petroleum gas field, reciprocating pump is used to conveying liquid to carry out oil and gas development, such as conveys drilling fluid
To at drill bit, catalase is aided in, cools down drill bit, cutting carring goes out well；Or for conveying fracturing fluid to carry out pressure break work
It is dynamic, or conveying liquid progress well-flushing etc..There is no reciprocating pump, oil and gas development activity just can not carry out.
Since reciprocating pump uses 3 cylinders or 5 cylinders more, the centre-to-centre spacing between cylinder sleeve flange and cylinder sleeve gland determines that reciprocating pump is arranged
Go out the centre-to-centre spacing of fluid cylinder, and determine the length of reciprocating pump crankshaft.In general, cylinder sleeve flange and cylinder sleeve gland are all circle, cause
Fluid cylinder centre-to-centre spacing is larger, and crankshaft length is longer, so as to cause the volume of reciprocating pump big, weight weight is of high cost, and transport and maintenance are not
Just.
Simultaneously as cylinder sleeve gland is with the structure for tapping disk, when striking tight cylinder sleeve can not accurate control mode, Wear resistance disk and
Liner packing easily fails.
Therefore, reciprocating pump volume is big, weight weight, of high cost, transport and maintenance inconvenience, job insecurity, inefficiency.

The cylinder sleeve connects the discharge fluid cylinder；
The cylinder sleeve gland connects the cylinder sleeve flange；
The studs connects the discharge fluid cylinder；
The studs connects the cylinder sleeve flange；
The nut connects the studs；
The nut connects the cylinder sleeve gland；
The gland locking plate connects the nut；
It is described to be bolted the gland locking plate；
It is described to be bolted the nut.
The nut includes two sections of screw threads；
The nut thread is internal thread.
The nut outer-hexagonal part is not in the nut end.
By adopting the above-described technical solution, the beneficial effects of the invention are as follows：
Cylinder sleeve gland and gland locking plate are abutted using straight line portion, are reduced cylinder spacing, are reduced crankshaft length, are improved
Bent axle force-bearing situation, alleviates weight；Using the nut with outer six side, can be driven with torque wrench etc., accurately
Control mode, improves reciprocating pump job stability, extends service life, has reached raising efficiency, reduces the purpose of cost.
