What Are Water Well Drillers?

Machinery and equipment for drilling water wells and completing downhole pipes and well washing operations. Including power equipment and drill bits, drill rods, core pipes, drill stands, etc. Generally divided into three categories of rotary machine, impact drill and compound machine.

Water well rig

Drilling

In the 2nd century BC, China already had the original percussion drill rig that drilled the cone with the help of a bamboo bow and struck the ground with the help of a bamboo bow. It has been used in rural China for a long time. It was not until the 1950s that wire rope impact rigs were introduced from abroad. In the early 1960s, simple water well drilling rigs, such as large and small pot cones, punching and grasping cones, were developed. Around 1966, the development of a positive circulation rotary rig was started. Around 1974, a reverse circulation rotary rig and a compound rig were successfully developed. In the late 1970s, a down-the-hole vibrating rotary rig was created. European and American countries mainly used wire rope impact rigs in the 19th century. In the 1960s, France first used rotary disc rotary rigs, which were later introduced to the United States and developed rapidly. In the 1950s, the development of reverse-circulation rotary rigs was started. Later, rotary rigs using compressed air instead of mud as well-washing medium appeared. By the 1970s, hydraulic powered rotary rigs were developed. ^[1]

1.Hydraulic oil pump: dual type, large displacement pump provides power for the power head, small displacement pump is four outrigger cylinders, lifting mast cylinders, afterburner / lifting

1. Power system, equipment that provides energy for the entire rig;

2. Working system, equipment that works according to the requirements of the process;

3. Transmission system, equipment for transmitting, transmitting and distributing energy for working units;

4. Control system, control various systems and equipment, coordinate and work accurately according to the requirements of the process;

5. Auxiliary system, equipment to assist the work of the main system.

Sealing lubrication of plate valve for water well rig accessories

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