Abstract
The utility model pertains to parts of petroleum drilling machinery, more particularly relates to a petroleum drilling mud pump assembling piston which comprises a T-shaped shaft; a rubber ring is sheathed on the centre shaft of the T-shaped shaft; and a round steel pressure-bearing baffle plate is arranged on the T-shaped shaft close to the end. The petroleum drilling mud pump assembling piston is characterized in that 3 to 8 triangular support plates are symmetrically arranged on the periphery of the end part of the T-shaped shaft; the two square edges of the triangular support plate are respectively connected with the centre shaft of the T-shaped shaft and the round steel pressure-bearing baffle plate; and a nylon pad is arranged between the rubber ring and the steel pressure-bearing baffle plate. The petroleum drilling mud pump assembling piston has the advantages that as the radiating efficiency of the round steel pressure-bearing baffle plate is improved, the service life of the rubber ring is prolonged by more than two times, the time for stopping work to replace the rubber ring for two times during drilling is saved, the drilling efficiency is greatly improved, the drilling cost is reduced, the economic benefit is remarkable, and the cost of round steel pressure-bearing column materials can be saved by about one third.
Description
Technical field
The utility model belongs to the oil drilling machine parts, particularly relates to the mud pump for petroleum drilling built-up piston.
Background technique
The termination of existing mud pump for petroleum drilling built-up piston is a very thick circular steel body pressure-bearing cylinder, and thickness reaches 30mm, so that can bear high pressure.But thickness reaches not only waste material very of 30mm, and it is few with the surface of contact of cooling water, also make cooling water have only seldom water space, poor from producing the built-up piston radiating effect, be unfavorable for the heat radiation of piston rubber ring, because the life-span and the temperature of piston rubber ring are inversely proportional to, too thick steel body pressure-bearing cylinder descends to the piston rubber ring operating life that makes built-up piston, and the piston rubber ring operating life of general this built-up piston had only about 100 hours.
Summary of the invention
The purpose of this utility model provides a kind of bearing strength that had both guaranteed the steel body pressure-bearing plate washer of built-up piston, can improve the mud pump for petroleum drilling built-up piston of the radiating efficiency of piston again.
Structure of the present utility model is:
The mud pump for petroleum drilling built-up piston of band heat radiation dunnage, comprise " T " font axle, be with rubber ring on the axis of " T " font axle, rubber ring is very thick also can be into rubber cup, " T " font proximal head that is coupling is provided with circular steel body pressure-bearing plate washer, circular steel body pressure-bearing plate washer is equivalent to the pressure-bearing function of existing circular steel body pressure-bearing cylinder, it is characterized in that: " T " font axle head head position periphery symmetry be provided with 3-8 piece triangular support plate, two right angle sides of triangular support plate respectively with the axis of " T " font axle with link to each other with circular steel body pressure-bearing plate washer, be provided with nylon pad between rubber ring and the circular steel body pressure-bearing plate washer.The purpose of triangular support plate is the pressure-bearing function that keeps the energy pressure-bearing uniform pressure of existing circular steel body pressure-bearing cylinder, but between each triangular support plate, produce the space of storage cooling water again, make the temperature of circular steel body pressure-bearing plate washer that better cooling effect be arranged, thereby prolong the operating life of the rubber ring at the circular steel body pressure-bearing plate washer back side, reducing stops work in the drilling well work changes the number of times of rubber ring, drilling well work is longer continuously, reduces drilling cost.
Preferably " T " font axle head head position periphery symmetry is provided with 4 blocks of triangular support plates.
The thickness of circular steel body pressure-bearing plate washer is 10-15mm.
Most preferably the thickness of circular steel body pressure-bearing plate washer is 12mm.Reduce and 18mm than existing circular steel body pressure-bearing cylinder thickness 30mm, Master Cost is saved one times, and radiating efficiency improves increases more than two times the rubber ring life-span, has lacked the time that rubber ring is changed in 2 shut-downs in drilling well work, and drilling efficiency improves greatly.
Advantage of the present utility model: because of the radiating efficiency raising of circular steel body pressure-bearing plate washer, the rubber ring life-span can be crossed about 200 hours, life-span increases more than two times, in drilling well work, lacked the time that rubber ring is changed in 2 shut-downs, drilling efficiency improves greatly, reduce drilling cost, economic benefit is fairly obvious.But but also the circular steel body pressure-bearing cylinder material cost about 1/3 of conserve expensive.
