The use performance of the straight breaker is inseparable from the specification and reasonable installation of various components, especially for the tools that use the hydraulic system as the power system. Generally speaking, because the excavator parts breaker is working, the hydraulic oil pump needs to be frequent The impact provides sufficient power for the bucket and the hammer of the hammer to carry out production work. Therefore, the connection requirements of the pipeline are higher. Next, I will give you a detailed explanation about the principle and requirements of the straight broken hammer tubing connection. I hope it will be helpful to everyone.
Before installation, the relevant accessories need to be protected. For example, to prevent mud and dust from entering the oil pipeline, plug the hose with a plug, and plug the pipeline with an internal thread plug. To prevent contamination by dust, the high pressure pipe and low pressure The tube is tied with wire.
The control valve (that is, the distribution valve) is generally reserved with a selection spool (there is a spool, the outside is a plug, and the one that is not connected to the pipe). Check the setting of the breaker for the oil return and judgment. The straight crusher has only 2 ports, one by one, one by one, one by one, and one by one, from high to low. Looking at the crusher manual, different brands may be different.
The oil inlet pipe is connected to the selection spool, and the oil return pipe is connected to the oil tank or any oil return point. One end of the pilot is connected with a handle or a foot pedal breaker switch corresponding to the solenoid valve interface, and the other end is connected with the selection valve core to the first conduit interface of the oil inlet of the connected breaker.
Pilot and then control the valve to connect another return oil. In short, one principle: there are in and out. Otherwise, the breaker will not sound. Note: The overflow valve of the breaker is connected to the oil inlet pipe, that is, the high pressure pipe.
It must be noted that the pressure should be relieved when replacing the straight type hammer, and the pressure relief valve is mostly set at the hydraulic oil tank, otherwise the hydraulic pressure will be ejected due to the pressure, which is dangerous to personal safety. Subsequently, the oil pipe can be blocked with toilet paper or other materials, and the leaked hydraulic oil can be collected in a container under conditions to avoid waste and environmental pollution.
