A novel dynamic seal structure for a drill rod driving assembly comprises a washing pipe, an upper packing pressing cap and a washing pipe lower seal pressing cap. A packing box is sleeved on the outer portion of one end of the washing pipe, a plurality of groups of alternately arranged spacer bushes and packing are arranged between the packing box and the washing pipe, the packing is V-shaped, the recessed direction of the V-shaped packing is the same as the direction of high-pressure water flow in the washing pipe, the upper packing pressing cap is installed on the outer portion of the packing box, a washing pipe lower seal ring is sleeved on the outer portion of the other end of the washing pipe, an O-shaped rubber seal ring and a steel wire baffle ring for shafts are arranged between the washing pipe lower seal ring and the washing pipe, and the washing pipe lower seal pressing cap is arranged on the outer portion of the washing pipe lower seal ring. By improving the shape and a setting mode of the dynamic seal structure, the service life of the dynamic seal structure is prolonged, so that usage time is prolonged, enterprise revenues are improved, and the novel dynamic seal structure simultaneously further has the advantage of being easy to dismantle and install.
Description
Technical field
The utility model belongs to petroleum refining industry delayed coking unit waterpower and cuts burnt technical field, specifically a kind of novel drilling rod driven unit movable sealing structure.
Background technique
Delayed coking is a kind of Petroleum Processing Technology, is to be raw material with the heavy oil, is warmed up to the pyrogenetic reaction temperature rapidly through oven, enters coke drum and carries out pyrogenetic reaction.Heavy oil carries out thermal cracking and the condensation reaction of the degree of depth, and the gas of producing, gasoline, diesel oil, wax oil are handled to downstream unit by pipeline, and the hundreds of ton coke of producing is stayed in the coke drum.Coke in the coke drum progressively is cooled to below 120 ℃ with steam, water, open the upper and lower end socket lid of coke drum then, coke in the coke drum is removed clean with hydraulic decoking equipment, close the upper and lower end socket lid of coke drum again, enter next step production cycle again: oil-feed, reaction, cooling, decoking etc.
Hydraulic decoking equipment generally includes: equipment such as decoking water pump, valve, sebific duct, drilling rod driven unit, drilling rod, decoking device, boring winch, sheave block.The high pressure decoking water that the decoking water pump produces, by the high pressure water passage that valve, sebific duct, drilling rod driven unit, drilling rod, decoking device are formed, the nozzle from decoking device sprays at last.
The washing pipe assembly is the critical component that connects the quiet end of high pressure water passage and moved end in the drilling rod driven unit, is made up of packing box, spacer, packing, last packing pressure cap, washing pipe, washing pipe lower sealing ring, washing pipe lower seal pressure cap etc.
At present, hydraulic decoking is similar to material filling type with water tap motive sealing form class, main pressured lid compresses the packing material increase power of holding tightly and plays the motive sealing effect, the length that increases filler is also favourable to the motive sealing effect, will certainly increase the surface friction drag of motive sealing like this, the consumption of power source power wastes energy.The heat of frictional force generation simultaneously has a strong impact on the filler life-span, needs the frequent filler of changing.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of novel drilling rod driven unit movable sealing structure, this structure is by improving sealing configuration shape and set-up mode, improved the life-span of movable sealing structure, therefore prolonged service time, improve the performance of enterprises, this structure also has easy-to-dismount advantage simultaneously.
The technological scheme that the utility model adopts is: a kind of novel drilling rod driven unit movable sealing structure, comprise washing pipe, last packing pressure cap and washing pipe lower seal pressure cap, end outer cover at washing pipe is provided with packing box, between packing box and washing pipe, be provided with spacer and packing that many groups are arranged alternately, described packing is the V-type packing, the depression direction of V-type packing is identical with washing pipe inner high voltage water (flow) direction, be equiped with the packing pressure cap in the outside of packing box, the other end outer cover at washing pipe is provided with the washing pipe lower sealing ring, be provided with O type rubber seal and axle-steel silk back-up ring between washing pipe lower sealing ring and washing pipe, washing pipe lower seal pressure cap is arranged on the outside of washing pipe lower sealing ring.
Also be provided with lubricating cup on the described packing box.
Also be provided with removal hole on packing pressure cap and the washing pipe lower seal pressure cap on described.
The beneficial effects of the utility model are: utilize the pressure of high pressure decoking water to be pressed on the V-type packing that improves the back packing, make packing V-type packing hold the washing pipe external diameter tightly, needn't apply excessive impacting force, reduced the area of contact between packing and the washing pipe, reduced heating value and improved sealing effect and life-span; The assembling of each part of washing pipe assembly forms an integral body, and two ends are threaded with pipeline, in case motive sealing has problem, can change by quick integral, keeps in repair shortening decoking system dead time under the line.
