When it comes to maintaining your hydraulic rockbreaker, absolutely the most important thing you can implement into your routine is lubricating the tool. This preventative maintenance routine can you save you time and money.

 

Manual greasing of your hydraulic hammer is often a real pain. However proper lubrication is critical to extending its life. It’s a painstaking but straightforward task to be repeated every two hours of continuous use, or when the tool becomes dry and shiny. Failure to grease regularly will significantly increase wear rates and reduce the lifespan of your tool, bushings, and front head components.

 

HOW TO GREASE YOUR HYDRAULIC ROCKBREAKER
 

Greasing Hydraulic Breaker Hammer

Firmly pressing the tool up inside the hydrualic rockbreaker prevents excessive grease from entering the impact chamber. Excessive grease in the impact chamber will cause a hydraulic lock, which depending on the amount, can cause a lack of power or immediate seal failure and ingression of grease into the hydraulic system when the rockbreaker is fired.

 

The hydraulic hammer must be in a vertical position to grease, with enough down-pressure to push the tool up inside the housing.

Grease until clean grease oozes out around the tool and retainer pins.

Grease hydraulic hammer after every two hours of continuous use, or when the tool appears shiny where it rides inside the front head.

Remember to use the manufacturer recommended grease. We recommend a the SLYM chisel paste or equivalent to lubricate all SLYM's hydraulic rock breakers. 

 

Don't want to grease your machine manually? SLYM offers a number of breaker mounted and carrier mounted auto-grease option for most of its rock breaker line, saving you time and effort.

All of steel chisel are subjected to wear and tear, become dull, so that even dull hammer to reduce their service life. A dull steel chisel will greatly reduce productivity, you must re-processing(sharpen).

 

The degree of wear and tear directly depends on the abrasion of the tool used inside of the minerals. Especially in the rock, quartz, or longevity stone calcium aluminum silicate content reaches 10% even under more circumstances it will cause a lot of wear and tear.

 

If the rock does not contain these substances, then the result of wear and tear is likely to be part of the steel chisel and liner contact.

 

There are three special steel chisel designs.
 

1. Cone steel chisel

 

This steel chisel shapes like a pencil tip, and is often used to pierce and object and penetrate the tool. In other words, even very hard objects can also be seprated by splitting power of point cone. Including, such as no reinforced or slightly reinforced concrete, sedimentary rock, and high hardness, seamy rock and so on.

 

Characteristics

 

1)The energy provided will have a very marvelous penetration when through point.

 

2)Split power being transmitted around.

 

3)No reverse
 

2. Flat Steel chisel 

 

These tools like stone mason’s chisel and are most widely used in the hydraulic hammer. Flat chisel works like cone chisel. Under the same working conditions, flat hammer is more wear-resistant. Because their shapes are more suitable for handing the reinforced materials, and thus flat chisel can smash the reinforced concrete better. So they are also recommended to break the heavy reinforced concrete, in addition, also widely used in sedimentary rocks, and the rock cracks of high hardness rocks.

1. Higher Density

 

In order to increase the wear-resistance of the steel chisel when in high strength operating condition, our experts choose top-quality alloy steel ingots for forging, so the density of the material is higher!

 

2. Better Toughness

 

In order to ensure the resilience of the steel chisel, our experts gain well-distributed and fine granular pearlite to make the steel chisel have good comprehensive functions by normalizing the raw material.

 

3. Stronger Wear-Resistance

 

In order to increase the wear-resistance, hardness strength of the steel chisel, our experts apply the techniques of segmentation quenching and tempering process, in addition they choose imported high-quality quenching medium.

 

4. Longer Service-life

 

In order to ensure longer service-life of steel chisel, our experts choose top-quality, refined alloy steel and improted quenching medium to do the heat treatment, so the hardness of our chisel core 50% higher than the average ones, seen from the point, our chisel have longer service-life.

 

5. Lower Breakage-Rate

 

The experts value the products quality very much, so raw materials before processing operations, heat treatment operations, production process and product testing are done on a fairly complete on order to keep the breakage-rate even lower.

 

 

Chisel production technology and manufacturing process

 

Forging----Turnery----Heat Treatment---Ultrasonic Flaw Detection---Hardness Test---Product Packing

 

 

1)The first kind of packing without exception:

 

1. In the low pressure oil pressure when not leak, causes assembly surface roughness is poor, - - - - - to improve the surface roughness of 3.2 ~ 6.3 umry with hardness lower seal

2. The piston rod of oil ring bigger, every stroke will drop a few drops of oil, causes shield of lip scrape oil film change dust ring type.

3. At low temperature heat leakage not leak, cause there are two one is eccentric too big a kind is packing material choose not appropriate, choose hardy of seal can solve the problem.  

 

 

2)The second type seal is not normal:

 

1. The main oil seal surface hardening, sliding surface have burst; Reason - - - - - abnormal high pressure is too high.

 

2. The main oil seal surface hardening, the seal oil seal rupture, broken to pieces; Reasons - hydraulic oil metamorphic oil temperature anomaly rise produce ozone damaged seal and produce oil leakage.

 

3. The main oil seal surface wear like mirror as smooth; Reasons - micro time pressure is too high stroke tiny.

 

4. The main oil seal surface mirror wear uniform packing have dissolved rise now like; Reasons - lateral pressure big eccentric is too large, with the bad oil and cleaning fluid.

 

5. The main oil seal sliding surface has damage and grinding crack; Reasons - plating is poor, have rust point matching surface roughness piston rod choose unsuitable material, containing impurities.

 

6. The main oil seal lip top have broken scar indentation; Reasons - assembly chamfering undeserved, installation, stored in a wrong way.

 

7. The main oil seal sliding surface pressure mark; Reasons - has foreign sundry.Eight. The main oil seal lip have crack fracture; Reasons - oil is undeserved, working temperature on the high side or low back pressure on the high side speed is too high, too much pressure pulse frequency.

 

9. The main oil seal has burned carbide metamorphism; Reasons - residual air produce adiabatic compression.

 

10. The main oil seal heel extrusion have crack; Reasons - pressure is too great, extrusion clearance is too large, bearing ring used for when, installation groove design is not reasonable.

Understand hydraulic hammer type of Numbers in meaning, the excavator user selection supporting hydraulic hammer are of great help.

 

1) According to the model direct matching hydraulic hammer

 

According to the mining 3.1 shrinking heavy matching hydraulic hammer

If hydraulic hammer model of digital representation for excavator machine weight (machine quality), can according to the mining of shrinking weight and hydraulic hammer type direct matching.

 

2) According to shovel bucket capacity matching hydraulic hammer

 

If hydraulic hammer model of digital representation for excavator bucket capacity, can according to shovel bucket capacity and hydraulic hammer type direct matching.

Aulic pipe is easy to pollution, according to the following method should be removed and installation.

 

1. Move the excavator to a piece of plain no mud, dust and debris field, shut off the engine, release the pressure of the hydraulic line and the gases of the email.

 

2. Put the the globe valve installed in at the end of the big arm rotate 90 degrees to the OFF position, in order to prevent the hydraulic oil flow out.  

 

3. Loosen the hose plug of hammer big arm first, then put the outing of a small amount of hydraulic oil access a container.  

 

4. To prevent dirt and dust into the pipeline, with plug will hose plugging with internal thread plug the pipeline plugging, to prevent dust pollution, should be high pressure pipe and low pressure pipe wire bundle good.  

 

- Hose plug

Equipment for bucket homework, plug is to prevent from the hammer of the dust of the world and the dust into the hose.

 

- Internal thread plug

Internal thread plug is to prevent adhesion in equipment host mud dust or dirt into the tubing.  

 

 

5. If you want to demount the broken hammer, must be arm connecting pin shaft removed; The outdoor storage broken hammer, should be put in the sleepers and BoPeng cloth cover it good.

 

6. broken hammer is not used for a long period, please click the method custody

1) clean up the broken hammer external;

2) Be removed from the steel on the shell, painted anticorrosive oil;

3) the piston to the nitrogen chamber after nitrogen chamber nitrogen be sent;

4) to assembly shall be broken hammer on all parts with oil, and then carry on assembly.  

 

7. such as the need to install broken hammer, the process and the aforementioned disassembly sequence instead. If for bucket operation, will be very easy to make hose and pipe end is pollution, polluted parts immediately clean up (please use the hydraulic oil or diesel oil to clean up)....

Selection of hammer in general to consider the following aspects:

 

1.  Fully consider the excavators weight can prevent large arm fully extended when the hammer weight caused the excavator tilting. Hammer may cause excessive large excavator tilting, too small and can not give full play to the efficacy of the excavator, damage will also accelerate the breaking hammer. Only the excavator and hammer weight match in order to give full play to the best performance of excavator and crusher hammer. In general, the excavator bucket capacity reflects the standard weight of the machine. A better method is currently according to the excavator bucket capacity to calculate the range can be selected and the breaking hammer.

 

Bucket capacity and hydraulic hammer weight have the following relationship: Wh= (0.6~0.8) (W4+ρ)

 

Type: Wh= W1+ W2+ W3 

 

W1-- hydraulic hammer body weight 

W2-- chisel weight 

W3-- hydraulic hammer frame weight 

W4-- excavator bucket self weight 

ρ - sand density, the general ρ =l600N/m3 

V-- excavator bucket capacity...
