Effieiency Portable Submersible Water Dredging Sand Pump

Pneumatic sewerage pump

QYF series intelligent mine pneumatic desilting sewage pump efficiency, is my company independent innovation, independent research and development, with independent intellectual property rights of drainage equipment series, product technology at the international leading level.

QYF series pneumatic desilting mine sewage pump powered by compressed air, suitable for methane coal dust explosion hazard of coal mine underground mining face roadway, bottom hole water nest, and sewage pit (well), such as water sump drainage drainage operation.

We developed QYF series pneumatic desilting mine sewage pump has realized the coal mine water warehouse of coal slime and water mixture good efficient processing, thoroughly remove the artificial dig water storehouse of heavy labor, at the same time, reduced the number of newly built underground water warehouse, not only improve the comprehensive economic benefits of the mine water CangQing dig, and implement the environment management and protection, save time and effort, has extensive practicability.

The technical characteristics of QYF series mining pneumatic dredging pump

1. This QYF series of dredging pump is advanced in structure, convenient in movement and stable in work. The working cycle is controlled by pneumatic timer, and the pump body has no moving parts.

Can adjust the timer according to the experience to improve the pumping efficiency.

2. The control system adopts the advanced air control valve to control and switch the actuator, and the safety performance is high and the action is sensitive and reliable.

The structure and working principle of QYF series mining pneumatic dredging pump

The main components of QYF series are main parts, control system and vacuum suction components.

1. Main body part: consists of pump body, feed pipe and discharge pipe, and its work is to absorb material and discharge.

2, control system, control system mainly using pneumatic directional control valve, shuttle valve, ball valve, and time is the combination of logical reversing valve body, realizes the control of the actuator and switch, reaches the unit work orderly transformation of absorb and layout.

3. Vacuum suction component: it is designed according to the principle of venturi effect, including air supply, vent and vacuum.

When the supply of gas supply pressure is higher than a certain value, the injection of supersonic jet nozzle, due to the viscosity of the gas, high-speed jet gas entrainment go negative pressure cavity, this cavity to form high vacuum degree.

The performance of the vacuum generator is related to the minimum diameter of the nozzle, the shape of the contraction and diffusion tube, the diameter of the nozzle and its relative position and the pressure of the gas source.

The vacuum suction component can be connected with the feed through the pump body, and the suction and discharge process of the unit can be completed when the control system is switched to control the cylinder
