4. Lower Noise and Vibration Operational noise and vibration levels are generally lower with DTH hammers, contributing to a more environmentally friendly drilling process and improving working conditions for operators.

Conclusion

The reason:
Inlet valve is not open or has silted
Suction line resistance is too high or blocked
Suction height is too high

Moreover, the ZJ pump is designed for easy maintenance. Its modular construction allows for quick access to critical components, reducing downtime during servicing. This feature is crucial in industries where every minute of operation counts, and any delay can result in substantial financial losses.

Drilling rig is a tool used to directly mine stone. It drills through rock layers to extract stone or other stone works.

CFM, or Cubic Feet per Minute, is a crucial metric in assessing the performance of air compressors. It indicates the volume of air that the compressor can deliver at a specific pressure level. The CFM 185 air compressor typically delivers an impressive 185 CFM, making it suitable for a wide range of applications that require substantial air supply. This high CFM rating enables the compressor to power multiple tools simultaneously, effectively enhancing productivity on job sites.

Progressive cavity pump slurry is a critical component in various industrial applications, particularly in the pump and vacuum equipment sector. This type of pump is designed to handle viscous fluids, slurries, and liquids with high solid content. Here are some key points to keep in mind about progressive cavity pump slurry:

(1) When using the drilling rig to drill, the driver should be placed in the drilling position, so that the front end is against the rock, and the distribution should be careful to let the drilling rig move forward, so that the drill bit touches the rock; When opening the hole, first quietly let the drilling rig drive, when the drill rod is in place in the rock, it is allocated to the full open position.
(2) Before starting the drilling rig, check whether the charging pressure of the accumulator is normal; Check whether the scouring water pressure and the lubricating air pressure can be; Check whether there is sufficient lubricating oil in the lubricator, and whether the oil supply is appropriate; Check the reverse tendency of the oil pump motor. (3) If the drilling rig cannot open the hole smoothly, it should first assign the rock drill to retreat, and then let the rock drill move forward to open the hole from the beginning.
(4) When replacing the drill bit, the drill bit should be gently pressed against the rock, so that the motor of the drill can be reversed to complete the sensitive unloading head.
(5) The inspection of hydraulic components can only be prevented under the condition of pole cleaning, and after the connecting tissue is removed, it must be quickly plugged with the cleaning tightly matched plug. Before the repaired rock drill is used from scratch, it is necessary to circulate the hydraulic oil into the oil circuit to wash the components of the hydraulic system.
(6) The oil level and oil supply of the lubricator should be checked regularly; The gear with reverse structure is regularly filled with high-temperature grease; Check the oil level in the lubricating oil tank regularly and remove the dirt in the oil tank
