Vertical hydraulic inner tube slurry pump

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...

AI Technical Summary

Problems solved by technology

There are various problems in the current mud pumps, such as large wear and short life of the slurry pump, high maintenance costs, and low head, which cannot be used for long-distance slurry transportation; diaphragm pumps are technically difficult and complex in structure , the pump is bulky, with a mechanical efficiency of about 85%. Under the same flow and pressure (head) conditions, the price of the entire diaphragm pump is the highest, which is several times to dozens of times the price of other pumps. At the same time, due to the high frequency of operation, it is easy to wear The components and their annual operating costs are also high. Diaphragm pumps require that the particle size of the transported materials be less than 1 mm; oil isolation pumps have environmental pollution problems, and have low intelligence and low mechanical efficiency; water isolation pumps have two problems of clean water consumption and slurry mixing. Big problem; the pipeline of the water diaphragm pump does not have the function of automatic adjustment of pressure and flow rate; the high-pressure water spray pump has the problem of wasting water resources

The above pumps are not suitable for use in the pipeline sand transportation system
