Why does the hydraulic rock hammer not carry out the blow job?

Good quality Heavy Duty Excavator Bucket for sales
We tried our first order in 2018, which was two years after I exchange my business card with Alice in 2016 Bauma conexpo India. Our supplier didn't finish our order on time, and it will cause around 100,000 USD lose to us. That's when we tried Huitong the first time. Huitong is good at dealing with rush orders, and the quality is very good.

—— Mr.Varun, Dealer, India

I work with Huitong the first time when I started my importing business. I've got tons of market insights from Jeremy. He is such a good friend being very tolerant to my bad temper. In 2017, Jeremy helped me handle a problem of bill of lading, which is caused by me. Huitong always emphasize that we should deal with the problem as soon as it occurs.

—— Mr.Stanislav Lilov, Bulgaria

We started cooperated with Huitong from 2017, they are honest, professional, always help us slove problems at the first step, we buy excavator attachments from Huitong in one stop, we share market insights like a good friend. Love Their Work.

Why does the hydraulic rock hammer not carry out the blow job?
Why does the hydraulic rock hammer not carry out the blow job?

The working principle of the hydraulic rock hammer is mainly through the hydraulic system to promote the piston to perform reciprocating work. Its output strikes can make the work go smoothly, but if you have the breaker not strike or strike intermittently, the frequency is low, and the strike is weak. What's the reason?

1. The hydraulic rock hammer does not have enough high-pressure oil to flow into the breaker without hitting it.

Reason: the pipeline is blocked or damaged; there is not enough hydraulic oil.

The treatment measures are: check and repair the supporting pipeline; check the oil supply system.

2. There is enough high-pressure oil, but the hydraulic rock hammer does not strike.

the reason:

1. Wrong connection of the inlet and return pipes;  

2. The working pressure is lower than the required value;  

3. The reversing valve core is stuck;  

4. The piston is stuck;  

5. The nitrogen pressure in the accumulator or nitrogen chamber is too high;  

6. The stop valve is not opened;  

7. The oil temperature is higher than 80 degrees.

The treatment measures are:

(1) Correct; (2) Adjust the system pressure; (3) Remove the valve core for cleaning and repair; (4) Whether the piston can be moved flexibly when pushing and pulling by hand. If the piston cannot move flexibly, the piston and guide sleeve have been scratched. The guide sleeve should be replaced, and the piston should be replaced if possible; (5) Adjust the nitrogen pressure of the accumulator or nitrogen chamber; (6) Open the shut-off valve; (7) Check the cooling system and reduce the oil temperature to working temperature.

 

3. The piston moves but does not strike.

In this case, the main reason is that the drill rod of the hydraulic rock hammer is stuck. You can remove the drill rod and check whether the drill rod pin and the drill rod are broken or damaged. At this time, just observe whether the piston in the inner jacket is broken and the falling block is stuck. If there is any drill rod, clean it up in time.
