Description
Technical Field
The utility model belongs to the technical field of the silt pump technique and specifically relates to a can clear up silt pump of jam automatically.
Background
A pump is a machine that delivers or pressurizes a fluid. It transfers the mechanical energy of prime mover or other external energy to liquid to increase the energy of liquid, mainly used to transfer liquid such as water, oil, acid-base liquid, emulsion, suspoemulsion and liquid metal, and also to transfer liquid, gas mixture and liquid containing suspended solid matter. Geological drilling rigs are drilling mechanical devices used for geological exploration and are commonly used in fields including coal fields, petroleum, metallurgy, mineral, geological, hydrological, nonferrous, and nuclear industrial exploration.
The general flow of drilling work is: before drilling, the position of the drilled well (i.e. the well position) is determined at the surface, and then the foundation for installing the drilling rig and the derrick and drilling rig are installed at the well position. During drilling operation, a drill rod and a drill bit are driven to rotate by the power of a drilling machine, and the drill bit gradually breaks down encountered rock strata to form a shaft (also called a borehole). The size of the borehole size to be drilled is determined by the size of the drill bit. While the drill bit is breaking up the rock formation, drilling fluid (commonly called drilling mud) is injected into the ground through the hollow drill pipe, and a large amount of rock debris generated by the drill bit breaking up the formation is carried to the surface by the circulating drilling fluid. After rock debris in the drilling fluid is removed, the drilling fluid is pumped into the well again through the drilling pump. The drilling fluid reaches the water hole of the drill bit through the inner hole of the drill rod and then returns to the ground from the annular space between the well wall and the drill string. The drilling process is that the drill bit breaks rock and the drilling fluid continuously carries out drill cuttings through circulation and forms a shaft.
In geological exploration, a drilling pump matched with a drilling machine is a sediment pump. The silt pump among the prior art is connected with inlet tube and outlet pipe, the silt pump during operation need add water in the pump body at first, the water that adds in the pump body this moment is called the diversion, when filling up the diversion in the pump body, start the silt pump, need earlier empty air in the inlet tube among the start-up process, then the silt pump gets into operating condition, at this moment the silt pump is through the inlet tube with water suction to the pump body in, water flows out from the delivery port, the outlet pipe of flowing through carries pit shaft depths, the water that is the medium is the water of no impurity best, but when outdoor operations, by environmental restriction, generally directly do the sediment once more with the water that has drill chip silt that overflows from the drill barrel and carry into the pump body once more, form a water circulation system.
The patent application number 201721321785.8 provides an automatic water injection device of a horizontal centrifugal pump, which utilizes the gravity action and the negative pressure principle to add water in a water storage tank into the water storage tank and then inject the water into the horizontal centrifugal pump, thereby solving the problem of automatic water injection. However, in geological exploration, the working site is frequently changed, and the device is not portable. The silt pump of prior art still has following problem when working: (1) after the water is used as a medium to bring the cuttings silt back to the ground, the cuttings silt is slightly precipitated in the water tank and enters the next circulation for recycling, and the water containing the silt is easy to block a water inlet pipe. (2) The upper cover of the pump body needs to be opened for water adding, and the water inlet pipe is frequently blocked and needs to be frequently restarted in combination with the water inlet pipe (1), so that the operation is troublesome. (3) Because the water inlet pipe is blocked, the integral pump body needs to be disassembled when silt is cleaned, the operation is troublesome, and the service life of the pump body is shortened
In view of this, this utility model is proposed.
