The circulation loop comprises a screw pump, a fourth pressure sensor, a temperature sensor, an observation container, a fifth pressure sensor, a spiral pipe and a ninth valve which are sequentially connected. By the system, the dynamic sand suspending ability and static sand suspending ability of various types of fracturing fluid can be tested, and the viscosity of various fracturing fluid can be measured through a falling-ball method.

an injection mold
The invention relates to the technical field of injection molds, in particular to an injection mold, an upper mold, a bottom plate and a lower mold; the lower mold is installed on the bottom plate, and the upper end of the bottom plate is fixed with a beam through two symmetrically arranged brackets, and the upper mold Driven by the driving assembly installed on the crossbeam to move up and down, the lower mold is provided with a movable mold, and the movable mold forms an injection flow channel with the upper mold and the lower mold. The lower end of the movable mold is fixed with a ring block, and the ring block It is placed in the annular oil cavity provided on the lower mold, and the annular oil cavity communicates with the oil supply assembly. The invention is novel in design, and the oil supply assembly absorbs the hydraulic oil in the annular oil cavity, so that negative pressure is generated in the annular oil cavity, and the movable mold is fixed. When the mold needs to be removed, the oil supply assembly supplies The oil plays the role of pressurization, so that the product after injection molding and cooling is moved up together with the movable mold, which is convenient for taking out the molded product.

The invention discloses an amphibious vertical sand discharging pump. The amphibious vertical sand discharging pump comprises a barrel-shaped pump body, wherein a water inlet is formed in the bottom of the pump body, and a water outlet is formed in the top of the pump body. A top cover, an upper bearing pedestal, a middle bearing pedestal, a lower bearing pedestal and a base are sequentially arranged in the pump body. The amphibious vertical sand discharging pump is characterized in that an axial flow type impeller is arranged at the end of a rotary shaft of a water pump motor, and an overflowpipe connected with a water inlet section is arranged on the inner side of the water inlet. The amphibious vertical sand discharging pump has the advantages that a relatively closed environment is formed by a self-suction water supply chamber, then the self-suction capacity of the pump body is greatly improved, the amphibious function is achieved, and the lift of land use is greatly improved; through a multi-stage impeller arranged on the rotary shaft in a sleeving manner, the lift of the pump body is increased, the problem that the pump inner pressure is too high is effectively solved by theoverflow pipe, and therefore the problem that liquid is leaked out to pollute the environment is effectively solved; and the axial flow type impeller guarantees that the total lift of the motor is free of overloads.
