Abstract
The utility model relates to a high-pressure scale removal pump plunger, which comprises a plunger body, a screw arranged in the plunger body and a nut connected with the screw, wherein steel sleeves are arranged at two ends of the plunger body; and screw holes are formed in the centers of the steel sleeve. By the high-pressure scale removal pump plunger, the cavitation of the top of the plunger can be prevented effectively, and the stable running of a scale removal pump is ensured, so that the service life of the plunger is prolonged, and the work efficiency of the high-pressure scale removal pump is improved obviously.
Description
Technical field
The utility model relates to descaling pump, specifically belongs to the high pressure descaling pump plunger.
Background technique
For guaranteeing the steel slab surface quality according with process requirements, the oxidation scale of steel slab surface must adopt pressure to hit up to the water injection of 380Bar and remove, and is qualified fully to satisfy the strip surface quality that is shut out behind the slab entering milling train.And hydraulic pressure is raised to the process of 380bar from 5bar in the piston high-pressure pump unit, mainly is to realize through the to-and-fro motion of plunger in cylinder sleeve.
Plunger is most important, the most flimsy mechanical component of high pressure descaling pump.Because plunger is in the hyperbaric environment for a long time, be prone to extrusion and damage, receive the erosion of various harmful matters in the water simultaneously, plunger surface and plunger seal performance can be affected.When the stupalith grade is low excessively, casting technique is selected the unreasonable of improper and plunger composite structure and is caused the long-time bearing operation, has just quickened the wearing and tearing of plunger, causes the plunger operational failure, and its main cause is that the top cavitation erosion causes due to the surfacial spalling.
The model utility content
The plunger head that the purpose of the utility model is to solve existing technology is cavitated to be influenced and causes the deficiency of surfacial spalling, and a kind of steel bushing that connects through the two ends at plunger is provided, thereby effectively opposing cavitation erosion influence improves the high pressure descaling pump plunger of life cycle.
Realize the technical measures of above-mentioned purpose:
Novel high-pressure descaling pump plunger, main by plunger body, be contained in the screw rod in the plunger body, the nut that links to each other with screw rod is formed, it is characterized in that: the two ends in plunger body are provided with steel bushing, are provided with screw hole at the center of steel bushing.
It is characterized in that: plunger body is a cylindrical body, or is respectively equipped with boss at its two ends, and steel bushing is sleeved on the boss.
The characteristics of the utility model: it can effectively prevent the plunger head cavitation erosion, guarantees the stable operation of descaling pump, and the life cycle of plunger obtains prolonging, and has significantly improved high pressure descaling pump work efficient.

Among the figure: 1-plunger body, 2-screw rod, 3-nut, 4-steel bushing, 5-screw hole, 6-boss.
Embodiment
Do below in conjunction with accompanying drawing and to further describe:
Novel high-pressure descaling pump plunger, mainly by plunger body 1, be contained in the nut 3 that the screw rod 2 in the plunger body 1 links to each other with screw rod 2 and form.Its two ends in plunger body 1 adopt docking mode to be bonded with steel bushing 4, at the center of steel bushing 4 processing screw hole 5.Also can also boss 6 be processed at plunger body 1 two ends, with steel bushing 4 be sleeved on the boss 6 back carry out bonding.
Above embodiment is merely example.
Claims (2)
