SGZ High Pressure Water Injection Flowmeter for Coal Mine

PRODUCT INTRODUCTION

Mine high pressure water injection meter is mainly used for coal seam water injection, water injection flow and water injection pressure measurement, can also be used to measure other high pressure conditions (such as high pressure, spray) water injection, flow and water pressure.

Structural composition

Mine high pressure water injection meter is mainly composed of upper shell, lower shell, impeller, impeller box, pressure plate, water quantity indicator and pressure indicator. Pressure gauge and high pressure water injection meter as one, easy to carry, easy to operate.

Working principle

The high pressure water injection meter for mine is installed in the water injection system pipeline. After the water flows into the water meter, the filter cover enters the impeller box along the tangential line of the lower cavity of the impeller box, pushing the impeller to rotate, the water rises in the impeller into the tangential line of the upper cavity of the impeller box and flows out. The impeller rotates through the permanent magnet above it to drive the center wheel above the pressure plate to rotate, and the center wheel drives the counting mechanism in the water quantity indicator to record the water quantity flowing through the water meter. The pressure of water injection in coal seam is indicated directly through the pressure measuring hole and through the pressure indicator.

Functional characteristics

 can measure the water quantity, flow rate and injection pressure of coal seam at the same time, light and easy to install and use;

 The water indicator adopts digital wheel type, which is intuitive and easy to read, and gets rid of the influence of the underground workers' not reading on the collection of water injection data of coal seam;

 The shell is made of diamagnetic impact anti-friction spark material;

 pressure indicator, designed and installed a special resistance bar to pulse the main pressure, so that the service life of the pressure indicator is greatly improved, and can be accurately read.

Main parameter

 Valley value range: 0.1m³/h to low pressure 0.06m³/h;

 Boundary flow: 0.25m³/h to low pressure 0.15m³/h;

 Common flow rate: 2.5m³/h to low pressure 1.5m³/h;

 Overload flow: 5.0m³/h to low pressure 3.0m³/h;

 Pressure measuring range: 0-25MPa;

 Measurement error: from including small flow rate to excluding demarcation flow rate of low range: ±5%;

From including the boundary flow to the high zone including the overload flow: ±2%;

The pressure measurement error is less than 1MPa;

Conditions of use

 Water temperature: -45-95℃;

 Water quality: non-corrosive industrial water or tap water for application;

 Water pressure: ≤25Mpa.
