ST 300 Pneumatic Borewell Machine Advantages:
1. The rig adopts an automatic telescopic rig, supported by two high-strength oil cylinders, and a set of hydraulic valves control the pitch of the rig, which saves time and effort in operation, is safe and reliable, and maximizes the benefits for users.
2. The chassis adopts rubber crawler, which is lighter in weight, which can reduce the noise of the vehicle's running mechanism, reduce the vibration of the vehicle body, and greatly reduce the fuel consumption. It can walk on urban roads without hurting the road surface.
3. The chassis comes with hydraulic high outriggers, which can be used for drilling rig leveling, loading and unloading trucks, and can be used as an auxiliary support when working.
4. The 24V electric start diesel engine is used to reduce the labor intensity of the operator, especially in the cold season, when the diesel engine is difficult to start, it shows great advantages.
5. This machine is equipped with BW-160 mud pump, which has large flow and pressure, and is convenient for maintenance. Parts and accessories are easy to purchase all over the country.
6. A hydraulic pipe screwing machine (75-168mm) can be optionally installed to improve work efficiency and reduce labor costs.
ST 300 Pneumatic Borewell Machine Operating Instructions:
During the working process of water well drilling rig, the pump is used for reverse circulation operation. Under the action of atmospheric pressure, the circulating fluid flows from the sedimentation tank to the bottom of the well through the return ditch along the annular gap of the well. At this time, the rotary table drives the drill pipe to drive the drill bit to rotate for drilling. The negative pressure established by the suction of the mud pump sucks the debris mud into the inner cavity of the drill pipe and discharges it into the sedimentation tank through the mud pump. The circulating fluid after sedimentation continues to flow into the well, The reverse circulation drilling work is formed.
