Abstract

The invention relates to a water conservancy mechanical facility, in particular to a vertical hydraulic inner tube slurry pump. The vertical hydraulic inner tube slurry pump comprises a vertical mortar cylinder, a mortar inner tube is arranged in the mortar cylinder, one-way floating ball valves are arranged in an inlet and an outlet of the mortar cylinder respectively, the mortar cylinder is connected with a plunger type water cylinder, the plunger type water cylinder is connected with a hydraulic oil cylinder, and a heat dissipating position indicator is arranged on the plunger type water cylinder. A plunger in the water cylinder is pushed by the hydraulic oil cylinder to do reciprocating motion to squeeze water in the water cylinder so that mortar in the mortar inner tube can be discharged outwards. The vertical hydraulic inner tube slurry pump has the advantages of being simple in structure, convenient to operate, high in pressure and efficiency, large in lift, environmentally friendly and safe and reliable to operate and consuming little energy, and the mortar conveying flow is large.

Description

(1) Technical field

[0001] The invention relates to a hydraulic mechanical facility, in particular to a vertical hydraulic inner tube mud pump. (2) Background technology

[0002] While promoting economic development, the coal resource mining industry has also brought many negative impacts, causing relatively serious geological and ecological damage, some rivers have been cut off, roads, bridges and culverts have broken and sunk, and hydropower facilities have been damaged. In the subsidence area of ​​coal mining, where water accumulates all the year round, the area of ​​cultivated land is reduced, grain production is reduced or completely eliminated, and agricultural economic losses are huge. The houses in coal-pressing villages are cracked, tilted, and collapsed, which has seriously threatened the safety of people's lives and property in the subsidence area.

[0003] The number of land-lost peasants caused by coal mining subsidence is increasing year by year, and the l...
