Drilling Water Well Drilling Rig

The water well drilling rig is a mechanical device that drills the water well and completes the operation of the downhole pipe and the well washing. Including power equipment and drill bits, drill pipes, core tubes, drill stands, etc. Generally divided into three categories: rotary transfer, impact drill and composite transfer.

In the 2nd century BC, China had used the original impact rig that used manpower and drilled the cone drill bit to impact the formation with bamboo bow elasticity. It was used in rural China for a long time. It was not until the 1950s that wire rope impact drills were introduced from abroad. In the early 1960s, simple water well drills such as large and small pot cones and punching cones were developed. Before and after 1966, the company began to develop positive-circulating rotary rigs. Before and after 1974, it successfully developed reverse-circulating rotary rigs and compound drilling rigs. In the late 1970s, it created a submerged-hole vibrating rotary drilling rig. In the 19th century, European and American countries mainly used wire rope impact drills. In the 1860s, France first used turntable rotary drills, which were later introduced to the United States and developed rapidly. In the 1950s, the development of a reverse-circulating rotary rig was started. Later, a rotary rig was used to replace the mud as a well-washing medium. In the 1970s, a hydraulic-powered rotary rig was developed.

Manual water well drilling rig accessories Flat valve thrust bearing adopts lithium-based grease. After each repair, check the consumption of grease. If it is found to be deteriorated, contaminated or missing, it should be replaced or replenished immediately. The valve cavity should be timely in every repair. Rinse and refill the sealant to lubricate the valve plate and seat. During the maintenance process, if there is a slight leakage at the seal seal of the valve stem seal, the sealant can be injected through the sealant injection valve on the bonnet to prevent leakage, but the seal should be replaced in time after the completion of construction. Before refilling the valve with the sealing grease, the internal pressure of the valve body must be considered first. The pressure of the high-pressure injection gun used must be greater than the internal pressure of the valve to successfully inject the sealing grease. Install the 7903 sealant in the injection gun and connect it to the injection valve on the valve bonnet through the hose. Operate the injection gun and inject the sealing grease.
