4. Material Analysis Understanding the material being processed can aid in selecting the most appropriate jaw plate type. Utilizing the right jaw plates for specific applications not only boosts efficiency but also reduces wear.

Before each day's operation, refill the 29 grease points with grease.

The submersible drilling rig, available in both internal combustion and electric models, is a device for drilling holes in rocks. The characteristics of drill drilling is outstanding, according to different characteristics can be divided into many varieties, different varieties of drill drilling scope is not the same, facing the classification of drill drilling, the way is briefly introduced as follows:

- Improved Performance in Tough Conditions Their design facilitates effective drilling in hard and abrasive materials, providing superior performance compared to standard cutting tools.

- Construction For foundations, pilings, and site preparation, DTH techniques enable precise hole placement and stability in challenging geological conditions.

3. Versatility DTH drilling is adaptable to various terrains and rock formations. It excels in hard and abrasive materials, making it a preferred choice for mining operations. Additionally, it can be effectively used in water well drilling, trenchless technology, and foundation drilling in construction projects.

First, the classification of drilling RIGS:
1, according to the use of the address is not the same, the drill can be divided into underground and open air two categories. According to the presence or absence of traveling structure, the drilling rig can be divided into self-propelled type and non-self-propelled type. There are many open-pit drilling RIGS in China, most of which are self-propelled.
2, according to the aperture is not the same, the drill can be divided into light drilling rig, medium drilling rig, heavy drilling rig.

The reason:The suction pipe is not filled with water
Blocked suction line or inadequate valve opening
The inlet pipe of the pump, the meter or the stuffing box are serious
