The surface of the base of the ISW single-stage single-suction horizontal centrifugal pump must be flat, clean and able to withstand the corresponding load;
ISW single-stage single-suction horizontal centrifugal pump installation precautions
1. The surface of the base of the ISW single-stage single-suction horizontal centrifugal pump must be flat, clean and can withstand the corresponding load;
2. Use anchor bolts where they need to be fixed;
3. For vertically installed pipeline centrifugal pumps, the anchor bolts must have sufficient strength;
4. If the pipeline centrifugal pump is installed vertically, the motor must be located above the water pump;
5, when fixed on the wall, pay attention to find the right alignment.
Start, run and stop of ISW single-stage single-suction horizontal centrifugal pump
1. Before the start of the ISW single-stage single-suction horizontal centrifugal pump, the pump should be filled with enough liquid to be transported, and no liquid-free start is allowed;
2. Close the outlet valve and check the steering of the pump immediately after turning on the power. The steering arrow of the pump must be consistent. Reverse operation is strictly prohibited.
3. When the pump reaches the normal speed after starting, gradually open the outlet valve and adjust to the required working conditions. The pump can work continuously for more than 3 minutes when the valve on the discharge line is closed.
4. When shutting down, first close the outlet valve and then cut off the power.
ISW single-stage single-suction horizontal centrifugal pump common troubleshooting
1. The installation of ISW single-stage single-suction horizontal centrifugal pump is reasonable, which has an extremely important impact on the normal operation and service life of the pump, so the installation and calibration must be carried out carefully;
2. Pre-bury the foot bolts according to the installation dimensions to do the concrete foundation work;
3. After the solidification of the base cement, the level of the pump and the motor shaft should be checked by applying the level on the pump installation;
4. Check whether the rotating parts of the pump are stuck or rubbed. The coaxiality of the pump shaft and the motor should be strictly checked. The sheet can be adjusted to be concentric. Finally, the coupling is rotated by hand, and the rotation is easy and uniform without rubbing. Be normal;
5, the pump suction and discharge pipelines should have their own brackets, the weight of the pipeline is not allowed to be directly received by the pump to avoid crushing the pump;
6. When the installation position of the pump is higher than the liquid level (within the allowable range of the suction stroke of the pump), the upper bottom valve should be installed at the end of the suction line, and the filling screw hole or valve should be set on the discharge line for the pump to start. For the purpose of pre-filling; when the installation position of the pump is lower than the liquid level, the control valve and the filtering device should be installed on the suction line to prevent the foreign matter from being sucked into the pump, and the filtering area should be 3-4 times larger than the pipe area;
7. The pump with high lift should also be equipped with a check valve on the outer end of the outlet flow control valve to prevent water hammer damage during sudden shutdown;
8, must ensure that the pump installation height meets the pump's NPSH, and consider the pipeline loss and medium temperature.
ISW single-stage single-suction horizontal centrifugal pump repair and maintenance
1. ISW single-stage single-suction horizontal centrifugal pump should regularly check the pump and motor to replace the vulnerable parts;
2, always pay attention to the bearing box with high-quality calcium-based grease to ensure a good lubrication of the bearing;
3. When the long-term shutdown is not used, in addition to the corrosive liquid in the pump, it is necessary to pay attention to the cleaning of each component and the inner flow passage of the pump and cut off the power supply;
4. The pump is strictly prohibited from running at no load;
5. If the medium contains solid particles, a filter should be added at the pump inlet.

Drag bits are economical tools when drilling softer geological formations and shallower depths. Step Drag Bit instal hard alloy bar .we supply both step drag bits and chevron drag bits. Step drag bits are usually used for drilling overdurdens with sands, clays or soft formations. Compared with chevron drag bits, step drag bits produce large cuttings and more aggressive, however, will be less durable.
drag bits features:
1, All drag bits blades originate from high quality alloy steel forgings.;2, Carbide inserts are individually brazed using 50% nickel silver alloy;
3, Use high grade carbide inserts only;
4, All drag bits are biult to the gauge tolerances
Step-type drag bits are very effective in drilling soft and unconsolidated material. They are available in a full range of sizes from 3-7/8" to 12-1/4".The design of step-type drag bits provides for fast drilling penetration and requires only moderate drilling weight for proper operation. A large center flushing hole is incorporated into our design for efficient removal of cuttings.
Connection threads: N-Rod, AW, 2 3/8"API Reg, 2 7/8" API Reg, 3 1/2" API Reg, 4 1/2" API Reg, 6 5/8" API Reg, 2 7/8" API IF, etc.Wings: Three wings, four wings or as your need .
