centrifugal pump shaft material


(2) If the shaft is different from the stuffing box axis, it is mainly due to processing errors and incorrect installation. Then pay attention to check whether the installation is correct after installation. If the sealing water ring is badly worn, a new water ring needs to be replaced. If the sealing water pipe is blocked, the sealing water cannot enter the middle of the packing, resulting in rapid wear of the packing, resulting in material leakage, you should dredge the blocked water pipe and keep the sealing water clean.

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.

Second, the use and characteristics of the drilling rig:
1). Use:
Engineering anchoring drill can be used in urban construction, railway, highway, river, hydropower and other projects to drill rock anchor hole, anchor hole, blasting hole, grouting hole and other drilling construction.
2). Features:
1, the drill selects the motor through the high-performance reducer as the reverse power; Use cylinders for propulsion. The hydraulic system is eliminated, so the mechanical efficiency is high, the cost is low, and the performance is stable.2, with anti-card maintenance, when the drill is stuck, the motor is not easy to burn, the reducer is not easy to damage.
