Concentrate for Hydraulic Support15-3

Concentrated liquid for hydraulic support

1. The implementation of standards

MT76-2011 "Emulsified oil, concentrated liquid and high water cut Hydraulic fluid for Hydraulic support".

2. Product specifications and models

H———————— Specifies the concentration code used

FAS——————— Applicable water hardness rating code

XX———————— concentrated solution

-X ———————— Product type code

"Product Type code" with capital letter H for hydraulic fluid, FAS for concentrated fluid; "Applicable Water Hardness Level Code" shall use Arabic numerals to represent the water hardness level applicable to the product; The Concentration Code for Required Use indicates the mass percentage of the concentration for required use of the product in Arabic numerals.

Example: HFAS15-5 is a concentrate for hydraulic support, which can be used in a 5% (mass ratio) concentration of water with a maximum hardness of 750mg/L and a maximum sulfate ion content of 720 mg/L.

3. Product performance

This product is transparent and homogeneous, with good lubrication, cooling, cleaning, rust prevention, corrosion prevention, low foam and adaptability to industrial water. It is suitable for hydraulic transmission medium of coal mine hydraulic support and hydraulic transmission medium of various single pillar.

4. Product characteristics

This product fully meets the technical requirements of concentrated liquid for hydraulic support in MT76-2011. The product features are as follows:

1. This product does not produce oil and soap analysis in operation, and no floating matter is precipitated in the liquid dispensing tank.

2, the column is not attached to the difficult to clean sludge, such concentrated liquid itself is easily soluble in cold water, and has good cold water cleaning.

3, in the operation of no sediment, can fall to the end.

4, prolong the service life of rubber seals, no system leakage phenomenon during normal operation.

5, no bacteria, fungi breeding does not produce rot, does not produce abnormal odor.

5. Usage methods and precautions

1, the concentrated liquid and the mixture of water according to the stock liquid: water = 5:95 (weight ratio), dilute evenly can be applied. The water for mixing liquid should meet the following requirements: no mechanical impurities and suspended matter in the water.

2. Compressed air, liquid flow circulation or spiral stirring can be used in the liquid dispensing tank to make the concentrated liquid uniformly dispersed in the water, otherwise it will cause the solution thin and thick, affecting the anti-rust effect of the upper part of the liquid dispensing tank and the air contact.

3. When detecting refraction, it is necessary to adjust the liquid distribution water to zero point and take samples in the liquid return pipe on the working face for refraction detection. When the indicator number of refraction meter is less than 2.0, the concentrated liquid should be supplemented in time, so as not to reach the required concentration and affect the performance.

4, this product can not be used as daily washing supplies, if accidentally splashed into the eyes should be immediately washed with plenty of water.

5. In the cold season, when the support or pillar is lifting the well, the diluent in the cylinder should be drained and the antifreeze for the hydraulic support should be added to prevent the cylinder and other hydraulic components from freezing.

6. This product shall not be mixed with the products of other manufacturers without test.

6. Storage and routine maintenance of concentrated liquid

1, Hydraulic support with concentrated liquid should be stored indoors, to prevent the sun and rain, storage temperature is not less than -5℃, do not mix with other oil.

2. The shelf life of the concentrated liquid is six months (based on the delivery date). After the expiry date, the concentrated liquid can be used only after passing the inspection.

3. Special containers and dispensing tools must be used for the use of concentrated liquid, and the containers and tools should be kept clean to avoid mixing impurities and affecting the quality of concentrated liquid.
