Abstract
The invention refers to an oil well pump and particularly relates to a reciprocating piston pump for drilling. The technical solution is as follows: the reciprocating piston pump for drilling comprises a hydraulic cylinder, a piston, a discharge valve, a valve box, a suction valve, a crank, a connecting rod and a piston rod, wherein the suction valve comprises a valve rod, a valve disk and a spring; the upside of the valve disk is connected with a pressing cap through a bolt, a vibration damping block is arranged between the pressing cap and the valve disk; the downside of the valve disk is connected with the valve rod; a valve base is arranged between outer edges of the vibration damping block and the valve disk and the valve box; the place where the outside of the valve rod is located at the valve disk is sleeved with a guide sleeve; a spring is sleeved on the valve rod outside the guide sleeve; the outer end of the valve rod is connected with a spring base; and the spring is fixed on the spring base. The reciprocating piston pump for drilling has the following beneficial effects that clearance volume of the original pump is greatly reduced through improvement of the reciprocating drilling pump, because the volume efficiency of the original pump is low and even the medium cannot be conveyed, and the pump after being improved can satisfy the requirements of pumping, thus the gas-containing drilling liquid is conveyed efficiently and the drilling work is finished; and furthermore, the improving method is simple and reliable.
Description
Technical field
The present invention relates to a kind of oil pump, particularly a kind of drilling well reciprocating piston pump.
Background technique
Existing drilling well is generally bigger with the cylinder inside clearance volume of reciprocating piston pump, if carry the drilling fluid that does not contain gas, because of the medium of carrying belongs to incompressible medium basically, so the clearance volume of pump is little to the proper functioning influence of pump.But when conveying drilling fluid with gas, because of the medium of carrying has very strong compressibility, after discharge process finished, the part drilling fluid with gas still remained in the cylinder inside clearance volume and can not discharge; After next circuit suction process begins; Remain in that high pressure drilling fluid with gas volume in the clearance volume expands thereupon, pressure decreases; Be lower than the pressure of suction line up to in-cylinder pressure; The low pressure drilling fluid with gas could get in the cylinder, thereby has reduced the actual liquid that sucks of each circulation significantly, and reciprocating pump efficient is low.
Summary of the invention
The object of the invention is exactly the above-mentioned defective that exists to existing technology, and a kind of drilling well reciprocating piston pump is provided.
Its technological scheme is: comprise oil hydraulic cylinder, piston, suction pipe, expulsion valve, clack box, suction valve, discharge tube, crank, connecting rod, piston rod; Described suction valve comprises valve rod, valve disc and spring, and the valve disc upside connects pressure cap through bolt, is provided with damping block between pressure cap and the valve disc; The valve disc downside connects valve rod; Be provided with valve seat between the outer of damping block and valve disc and the clack box, the valve rod outside is positioned at the valve disc place and is with guide sleeve, and spring housing is on the valve rod in the guide sleeve outside; The valve rod outer end is connected with spring seat, and spring is fixed on the spring seat.
The invention has the beneficial effects as follows: through transformation reciprocating drilling pump; Reduced the clearance volume of former pump greatly; Make the low even medium that can not carry of original pump volumetric efficiency also can satisfy the requirement of pumping through improved pump; Realized efficient conveying drilling fluid with gas, accomplished drillng operation, and it is simple, reliable to improve one's methods.
