Abstract
The utility model provides an oil outlet pipe assembly for a dry oil pump, belonging to the mechanical field. The oil outlet pipe assembly consists of an oil outlet pipe, a sealing and fastening joint and a sealing and fastening nut. One end of the oil outlet pipe is equipped with a conical joint having threads, and the other end of the oil outlet pipe is equipped with a spherical joint, which is connected and fixed with the sealing and fastening joint via the nut. The oil outlet pipe assembly of the utility model eliminates the phenomenon of oil leakage of oil outlet pipes of dry oil pumps, and thereby reduces oil loss.
Description
Technical field
The utility model belongs to mechanical field, is specifically related to a kind of dry oil pump oil outlet tube assembly.
Background technique
The operation of dry oil pump mainly is to drive the fuel feed pump plunger bar through motor by bent axle in cylinder sleeve, to move reciprocatingly; Drier oil is got from the cylinder sleeve oil outlet; Be connected fixing selector valve through oil outlet tube and with it, drier oil under high pressure is transported to each fuel feeding point of equipment then.In the dry oil pump working procedure, owing to bear the high pressure about 10MPa, and moved the influence of vibrations; Leakage of oil often takes place in sealing tightening nut place; Copper sheathing in the process of nut screwing clamping very easily is out of shape again and weares and teares, thereby increase the weight of leakage of oil, influence the normal fuel injection of equipment; Cause oil consumption to increase, the plant maintenance workload increases.
Summary of the invention
The utility model provides a kind of dry oil pump oil outlet tube black box, in order to the elimination oil leakage phenomenon, and dismounting, easy for installation, reach reduction oil consumption loss, reduce labor intensity.
The utility model is made up of oil outlet tube, sealing fastening and sealing tightening nut; One end of oil outlet tube is the taper connection head; The taper connection head is provided with screw thread, and the other end of oil outlet tube is the convex spherical joint, and the convex spherical joint is connected with the sealing fastening; The sealing fastening is the spill spherical joint supporting with the convex spherical joint, and the convex spherical joint is connected fastening with the sealing fastening through nut.
Described oil outlet tube is that diameter phi is that 18mm, length are the pipeline of 110mm;
The tapering of the taper connection head of one end of oil outlet tube is 1:15, and the screw thread on the taper connection head is M18 * 1.5; The other end is the convex spherical joint, spherical radius R=9mm.
Described sealing fastening length is 30mm; One is the spill spherical joint, and spherical radius R=9mm, connecting thread are M24 * 1.5; The other end is tapered thread M18 * 1.5, and its tapering is 1:15.
Described sealing tightening nut length is 15mm, and connecting thread is M24 * 1.5.
The utility model has been eliminated dry oil pump oil outlet tube oil leakage phenomenon, thereby reduces the oil consumption loss.
