What is the reason why the rocker arm of the shearer rises and falls

Summary. Dear, hello, I am glad to answer for you what is the reason why the shearer rocker arm does not move or lifts slowly? Answer: There are many possible reasons for this, and we need to check them one by one.

1. Check if the pressure of the high-pressure gauge of the pumping station is enough? 2. Then look at the interface between the pump station and the high-pressure pipe of the hydraulic cylinder to see if there is oil leakage. 3. If there is no problem with the above, then maybe your height adjustment cylinder is broken.

I work as a shearer.

What is the reason why the shearer rocker arm does not move or lifts slowly?

What is the reason why the oil level of the coal engine is normal, but the rocker arm cannot be lifted by the manual remote control?

Dear, hello, I am glad to answer for you what is the reason why the shearer rocker arm lifting does not move or lifts or is slow? Answer: There are many possible reasons for this, and we need to check them one by one. 1. Is the pressure of the high pressure gauge of the pumping station enough?

2. Then see if there is oil leakage at the interface between the pump station and the high-pressure pipe of the hydraulic cylinder. 3. If there is no problem with the above, then maybe your height adjustment cylinder is broken. I work as a shearer.

Summary. First of all, consider whether the pipeline is clogged or the pipeline is leaking, which is a good way to check whether the oil outlet is blocked to see if the pressure changes. Secondly, check whether the gear pump is seriously worn, and the gear pump with serious wear is not able to supply oil to the oil cylinder, or the oil supply pressure is not enough.

Again, check whether the hydraulic lock of the cylinder can not seal the oil. Neither the left nor right can be a problem with the first two, or a problem with the multi-way directional valve.

Neither the left and right sides can be a problem with the first two, and there may be a problem with the multi-way reversing valve.

Dear, I hope mine is helpful to you, thank you for the praise.

What is the shearer left swingarm lifting, descending control process.

1. Electric traction shearer, high pressure is used to raise the rocker arm, low pressure is used to open the brake of the shearer, when the remote control is used to adjust the high, the solenoid valve first controls the low pressure, the low pressure and then moves the hand hydraulic reversing valve, and then the high pressure is raised. 2. Hydraulic traction shearer, high pressure is used to adjust the traction of each mining machine of the rocker arm, low pressure is used to open the brake and control the hand hydraulic reversing valve to adjust the height, as well as to make oil and heat exchange for the traction closed circuit. 3. The function of the hydraulic system is to increase the force by changing the pressure.

A complete hydraulic system consists of five parts, namely power components, actuators, control components, auxiliary components (accessories) and hydraulic oil. Hydraulic systems can be divided into two categories: hydraulic transmission systems and hydraulic control systems.

The hydraulic transmission system takes power transmission and movement as its main function, and I hope it can help you. If my answer is helpful to your friends, please give a thumbs up (comment in the lower left corner), look forward to your like, your efforts are very important to me, and your support is also the driving force for my progress. Finally, I wish you good health and a good mood!

Summary. Hello, the main reasons for the rocker arm to descend are: 1. The hydraulic control check valve is not tightly sealed. 2. The piston seal in the height adjustment jack is damaged, and the oil is channeled in the two chambers. 3. There is oil leakage in the joint in the tubing.

You can see if these three reasons are responsible!

What is the matter with the rocker arm of the coal machine rising up and lowering itself.

Hello, the main reason for the rocker arm decline is: 1. The hydraulic control check valve is not tightly sealed. 2. The piston seal in the jack is damaged, and the oil is channeled in the two chambers. 3. There is oil leakage in the joint in the tubing. You can see that it is not blind to socks because of these three reasons!

Hope it can help you solve the problem as soon as possible!
