The utility model discloses a composite ceramic piston rod hydro -cylinder is ground to intermediate speed, simple structure, reasonable in design, fail safe nature is high, and this piston rod has better anticorrosive wear resistance, lengthens the life of piston rod, reduces maintenance cost, has reduced environmental pollution when bringing bigger economic benefits, possesses fine practicality.
Description
Technical field
The utility model belongs to power plant's grinding production line technical field, is specifically related to medium speed grinding composite ceramics piston rod oil cylinder.
Background technique
At present, the roller ring mill that power plant's grinding system generally uses, all become load cylinder by medium speed grinding to pull grinding roller to carry out the grinding of coal cinder, due in grinding process, coal cinder not of uniform size, hardness differs, medium speed grinding is impelled to become acting frequently of load cylinder, this just requires very high to the wear resistance of piston rod, the manufacturing process of cylinder piston rod mainly adopts the mode of electrochromism in the market, but chromium plating meeting stopper rod is after long-term operation, still there will be corrosion, wear phenomenon, especially this acting frequently is run into, discontinuity, carry large situation, piston rod serious wear, working life is short, hydraulic pressure has leakage serious, annual each power plant all needs to spend huge financial resources, manpower is safeguarded.
Therefore electrochromism fundamentally can not solve anticorrosion, the wear-resisting problem of piston rod, and the material that electrochromism produces is a kind of carcinogen, serious environment pollution.
Model utility content
Goal of the invention: the purpose of this utility model is to provide medium speed grinding composite ceramics piston rod oil cylinder, solves the Fast Wearing problem that medium speed grinding becomes load cylinder piston rod, extends service life of equipment, is easy to maintenance and safeguards.
Technological scheme: for achieving the above object, the utility model adopts following technological scheme:
Medium speed grinding composite ceramics piston rod oil cylinder, comprises piston rod, oil cylinder guide sleeve, cylinder tube, oil cylinder bonnet, piston and Seal Kit; Described oil cylinder guide sleeve suit is arranged on the periphery of piston rod, and piston rod is screwed on piston, and piston sleeve is contained in cylinder tube; One end and the oil cylinder guide sleeve of described cylinder tube spin, and the other end and oil cylinder bonnet spin.
Described piston is provided with piston channel, Seal Kit is set in piston channel.
Described oil cylinder guide sleeve is provided with piston channel, Seal Kit is set in piston channel.
Described screw-on place is all sealed by Seal Kit.
Shown piston rod is the piston rod of 45# steel matter, and the hardness of piston rod is HRC55-60.
Ceramic layer is provided with in the periphery of described piston rod.
Beneficial effect: compared with prior art, medium speed grinding composite ceramics piston rod oil cylinder of the present utility model, structure is simple, reasonable in design, safety reliability is high, and this piston rod has better anticorrosion antiwear performance, extend the working life of piston rod, reduce maintenance cost, decrease environmental pollution while bringing larger economic benefits, possess good practicability.
Accompanying drawing explanation
Fig. 1 is the plan view of medium speed grinding composite ceramics piston rod oil cylinder;
Fig. 2 is the side view of medium speed grinding composite ceramics piston rod oil cylinder.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, medium speed grinding composite ceramics piston rod oil cylinder, comprises piston rod 1, oil cylinder guide sleeve 2, cylinder tube 3, oil cylinder bonnet 4, piston 5 and Seal Kit 6.
Piston rod 1 is screwed in one end of piston 5, and piston 5 is sleeved in cylinder tube 3, and piston 5 is provided with piston channel, arranges Seal Kit 6 in piston channel.
One end and the oil cylinder guide sleeve 2 of cylinder tube 3 spin, and the other end and oil cylinder bonnet 4 spin, and screw-on place is all sealed by Seal Kit 6.
Oil cylinder guide sleeve 2 suit is arranged on the periphery of piston rod 1, oil cylinder guide sleeve 2 is provided with piston channel, arranges Seal Kit 6 in piston channel.
As shown in Figure 2, piston rod 1 45# steel is done, and makes surface hardness reach HRC55-60, then by plasma spray technology, ceramic powder is sprayed at piston rod surface through quenching with Subsequent tempering and surface high frequency Quenching Treatment, ceramic layer, and reach piston rod required size and surface roughness by Hang grinding process.
Working procedure: in the working procedure of medium speed grinding composite ceramics piston rod oil cylinder, by piston 5 piston rod 1, sealing and guiding is realized by oil cylinder guide sleeve 2, cylinder tube 3, oil cylinder bonnet 4 fitted seal external member 6, by the piston rod 1 and the ceramic layer that adopt surface hardness to reach HRC55-60, improve wear-resisting property.
