Description
Technical field
It the utility model is related to a kind of pump, more particularly to a kind of slush pump.
Background technology
Slush pump refers in drilling process to the machinery of the conveying flushing liquor such as mud or water in drilling.Slush pump is probing
The important component of equipment.In conventional direct circulation probing Zhong ﹐, it is by earth's surface scouring media -- Qing Shui ﹑ mud or polymerization
Thing flushing liquor under pressure, the bottom through the soft pipe ﹑ taps of too high pressure and drill string central hole direct sending drill bit, to reach
Cooling drill bit, the landwaste cut is removed and is transported to the purpose of earth's surface.Conventional slush pump is piston type or plunger type
, the crank up of pump is driven by engine, band piston or plunger move reciprocatingly bent axle in pumping cylinder again by crosshead.
In the case where sucking the alternating action with dump valve, the purpose of force feed and circulating flushing washing lotion is realized.Regardless of whether it is the mud of which kind of form
Pump, without barrier, often occurs that mud, water pour into and hydraulic pressure is damaged in hydraulic cylinder between hydraulic cylinder and pump head during use
The problem of system.
Utility model content
The purpose of this utility model a kind of is preventing water and mud to the slush pump poured into hydraulic cylinder in providing.
The utility model provides a kind of slush pump, and it includes hydraulic cylinder and pump head, it also include be connected to hydraulic cylinder with
Water proof seat between pump head, the outer end of hydraulic cylinder piston rod are stretched into pump head through water proof seat, and the piston rod in pump head is provided with
Piston.
Preferably, the water proof seat is assembly parts, including be sequentially arranged from first flange from hydraulic cylinder to pump head, connection
Set and second flange, water proof seat are connected as a single entity with first flange and hydraulic cylinder, are connected with second flange with pump head.
Preferably, the cylinder body of the hydraulic cylinder is provided with the ring flange for being used for connecting the first flange.
For the ease of the replacing of piston, make the piston rod of the hydraulic cylinder include the section of foundation that is detachably connected as a whole and
Quick change section, the inner of section of foundation are located in hydraulic cylinder body, and the outer end of quick change section is stretched into the pump head.
The effect of reverse-filling in order to better improve, the opening position in the quick change section in connector are provided with gear mud
Plate.
As a kind of connected mode being detachably connected, the outer end for making the section of foundation is thread head, the quick change section
The inner is provided with screwed hole, and section of foundation is threadedly coupled with quick change section and is integrated.
As another connected mode being detachably connected, the connected mode that can also make the section of foundation and quick change section is
Pin connection.
For the ease of the replacing and maintenance of piston, the piston rod of hydraulic cylinder can also be made to be included in the water proof seat inner flange
The section of foundation and quick change section connected as one.
The utility model between hydraulic cylinder and pump head by setting water proof seat to avoid the mixture such as mud during use
Pour into hydraulic cylinder, avoiding foreign matter from pouring into hydraulic cylinder prevents hydraulic system contaminated or damage.

The present embodiment in use, can be avoided effectively by the water proof seat being arranged between hydraulic cylinder and pump head
The mixtures such as mud are poured into hydraulic cylinder, so as to protect hydraulic system not contaminated or damage.Pass through the setting of mud guard simultaneously
Further prevent mud from entering.And the piston rod of oil cylinder is arranged to assembly parts, including the section of foundation that threaded connection is integrated
With quick change section, because piston is consumable accessory during slush pump use, piston is connected in quick change section, facilitate maintenance and more
Change.
Preferred embodiment two, the difference of the present embodiment and preferred embodiment one with by the connection side of section of foundation and quick change section
Formula is designed as pin connection.
Preferred embodiment three, the difference of the present embodiment and preferred embodiment one with by the connection side of section of foundation and quick change section
Formula is designed as flange connection, and two adpting flanges is subrogated in water proof seat, and anti-mud is realized with adpting flange substitution mud guard
The effect poured in down a chimney.
In above-mentioned three kinds of embodiments, it can use a pair of connecting plates that first flange and second flange are connected as a single entity, as even
The alternative solution of female connector.
