Pneumatic Dredging Sewage Pump

Introduction to pneumatic dredging sewage pump

The pneumatic dredging sewage pump uses the principle of vacuum negative pressure to suck the coal slurry into the material tank and discharges the material by using compressed air. Its advanced aerodynamic vacuum concept makes the mine pneumatic dredging sewage pump reach the international level. Specially designed for the pumping of high-solid-content materials, it has a good treatment effect on mud and coal slurry containing solid particles such as coal rock, slag, wood chips, metal objects, etc. and is very suitable for coal mine mud, oil-based mud, concrete waste, municipal sewage, aluminum sludge, river dredging, and other fields.

Technical characteristics of the pneumatic dredging sewage pump

1. This series of dredging pumps has an advanced structure, is easy to move, and has stable work. The working cycle is controlled by a pneumatic timer, and the pump body has no moving parts. The timer can be adjusted empirically to improve pumping efficiency.

2. The control system adopts an advanced pneumatic control valve to realize the control and switching of the actuator with high safety performance and sensitive and reliable action.

Advantages and characteristics of the mine pneumatic dredging sewage pump

1. Strong pollution ability can pump materials with high solid content with fluidity.

2. Pure pneumatic products, without any electronic devices, are safe and reliable.

3. The unit has a compact structure and an ingenious design that can realize automatic operation.

4. The moving parts are not in contact with the material, resulting in no wear, stable operation, and a long service life.

5. No damage to the equipment due to no load or overload, and simple maintenance.

6. Small size, light weight, flexible movement, easy operation, wide range of applications.

7. Low energy consumption, energy savings, and environmental protection.

QYF Series Mine Pneumatic Dredging Sewage Pump

Product structures and working principles of the QYF series mine pneumatic dredging sewage pump accessories

The main components of QYF series mine pneumatic dredging sewage pump accessories include the main part, control system, and vacuum suction components.

1. The main part is composed of a pump body, a feeding pipeline, and a discharging pipeline, and its work is to suction and discharge.

2. Control system: The control system mainly uses the organic combination of pneumatic reversing valve, shuttle valve, ball valve, and time logic reversing valve to realize the control and switching of the actuator, so as to achieve the orderly conversion of suction and discharge when the unit is working.

3. Vacuum suction assembly: It is designed according to the principle of the Venturi effect, including an air supply port, an exhaust port, and a vacuum port. When the air supply pressure of the air supply port is higher than a certain value, the nozzle shoots out a supersonic jet, and due to the viscosity of the gas, the high-speed jet sucks away the gas in the negative pressure chamber, so that the chamber forms a higher vacuum. The performance of the vacuum generator is related to many factors, such as the minimum diameter of the nozzle, the shape and diameter of the shrinkage and diffusion tubes, their relative positions, and the amount of air pressure. The vacuum suction assembly communicates with the suction port through the pump body, and when the control system switches to control the cylinder in cycle, the suction and discharging processes of the unit can be completed.

Using conditions of the QYF series mine pneumatic dredging sewage pump

a) The dredging pump is submerged by the suction pipe inlet.

b) The temperature of the conveying medium shall not exceed 40°C.

c) Working environment temperature (5~40) °C.

d) The PH of the conveying medium is in the range of 4~10.

e) The maximum diameter of the particles containing solids does not exceed 20 mm.

Applicable air pressure range: 0.60MPa~0.70Mpa

Main features of the pneumatic dredging sewage pump

The pneumatic dredging sewage pump is driven by compressed air, and the main components include the main part, control system, and vacuum suction assembly. The QYF series mine pneumatic dredging sewage pump is suitable for the cleaning of a large amount of slime precipitated in the underground water tank of the coal mine. Because there is no reliable equipment to clean the slime, it not only brings a lot of inconvenience to the normal production of the coal mine but also causes a great waste of resources. The sewage pump we developed realizes the efficient and fast treatment of the sludge water mixture in the underground water tank of the coal mine, completely relieves the heavy labor of manual excavation of the water tank, and reduces the number of new underground water silos, which not only improves the comprehensive economic benefits of the mine water bin excavation but also realizes the governance and protection of the environment, saves time and effort, and has a wide range of practicability.

Maintenance of the pneumatic dredging sewage pump

Sewage pumps require less maintenance and are easy to do. Please follow the procedures below for maintenance.

1. Daily: Check whether the pump is damaged and whether the cover plate and safety card lock are fixed.

Check that the discharge line is securely fastened and not loose.

Inspect all hoses for damage or wear and, if necessary, replace them.

2. Monthly: Check the lubricating oil level, add if necessary, and ensure the basic amount of lubricating oil required for operation.

Check that the discharge line is securely fastened and not loose.

Inspect all hoses for damage or wear, and replace them if necessary.

Transportation and storage of the pneumatic dredging sewage pump

The pneumatic dredging sewage pump can be used by conventional means of transportation, and there should be reliable positioning and waterproof measures during transportation to prevent vibration and impact. It is strictly forbidden to be barbaric loading and unloading, and it shall not be mixed with corrosive substances for transportation. The product shall be stored in a ventilated and dry warehouse in an upright position and shall not be stored in the same warehouse with corrosive substances.
