4.1 rubber lined impeller maximum lift should not exceed 63m. Maximum allowed speed used should not exceed 30m / m.

4.2 Rolling bearings are generally used, and the use of thin oil or grease lubrication, its working temperature should not exceed 75 ° C.

4.3 slurry pumps manufacturer drive optional flexible coupling, belts or other fluid coupling. Couplings, V belt and pulley should be security guards.

4.4 For the rubber casing bivalve slurry pumps manufacturer, slurry the solid particles should not exceed the maximum size of 3mm, no sharp edges; slurry pumps manufacturer for a single shell, the metal inner shell bivalve slurry pumps manufacturers, slurry maximum particle size of the solid flow cross-section should not exceed 80% of the minimum size.

4.5 packing seal water pressure should be higher than the slurry pumps manufacturer discharge pressure of 35kPa.

Slurry various selection formula

Now the industry standard slurry pumps manufacturer selection formula lists, formulas, the symbols have carried out unity.

1) Typical slurry method

Line features:

Shimizu Hf = Δ H + (1 + ξ) (V ^ 2) / (2g)

Slurry Hmo = ΔΗ +0.72 Ko (Vl ^ 2) +0.5 8 Ko (V ^ 2)

Slurry pumps manufacturer features:

Slurry Hm = ΔΗ +0.72 Ko (Vl ^ 2) +0.58 Ko (V ^ 2)

Shimizu Hs = Hs * HR

2) Coal Act 1

Line features:

Shimizu Hf = Δ H + iL +2

Slurry Hmo = ΔΗ + imL +2

Slurry pumps manufacturer features:

Slurry Hm = ΔΗ + imL +2

Shimizu Hs = H / Km

3) Calculation ash

Line features:

Shimizu Hf = Δ H +1.05 iL

Slurry Hmo = ΔΗγ m +1.05 imL

Characteristics of the slurry pumps manufacturer

Slurry Hm = 1.1Hmo

Shimizu Hs = Hs * γ m * Km

4) Calculation of tailings

Line features:

Shimizu Hf = Δ H + iL + Σ hi

Slurry Hmo = ΔΗγ m + imL + Σ hi

Slurry pumps manufacturer features:

Slurry Hm = ΔΗγ m + imL + Σ hi

Shimizu Hs = Hs * γ m * Km * Kh

5) filling mining method

Line features:

Shimizu Hf = Δ H +1.05 iL + Σ hi

Slurry Hmo = ΔΗγ m + imL + Σ hi

Slurry pumps manufacturer features:

Slurry Hm = ΔΗγ m + imL + Σ hi

Shimizu Hs = Hs * Km * Kh

6) metallurgical and mining law

Line features:

Shimizu Hf = Δ H + iL + Σ hi

Slurry Hmo = ΔΗγ m + imL + Σ hi

Slurry pumps manufacturer features:

Slurry Hm = ΔΗγ m + imL + Σ hi

Shimizu Hs = Hs * γ m * Kh

And significance of symbols in the formula

Hf, Hmo, Hm, Hs piping water slurry head and head, head and water slurry pumps manufacturer head;

Δ H head loss;

L pipe length;

i, im clean water and slurry friction factor;

Kh = 1-0.25Cw

γ m slurry specific gravity;

Ko = H / (V ^ 2), water pipe head calculating the ratio of the velocity squared.

Vl critical settling velocity.

Km = Hm / (Vm ^ 2) slurry pipeline head calculating the ratio of the velocity squared.

Slurry parameters:

Flow: 50 to 1800 cubic meters per hour

Head: 24 ~ 94 meters

HEAD: 24 ~ 94  

Capacity: 17 ~ 1267 cubic meters per hour

Motor power: 11 ~ 710kw

Motor power: 11 ~ 710kw

Product Standard: JB/T809 6-1998

Lifting Matters

 

1, lifting without base or stand alone with only the horizontal slurry pumps manufacturers, lifting the focus should be on the bay side of the square hole near the head office, which passes through the wire rope should be straight up with the lifting hook connection. In order to maintain the balance of the slurry pumps manufacturer should be on the slurry pumps manufacturer housing screws and lifting hooks rings disposed between the auxiliary hoisting rope. Bracket cover and front eye bolts on the slurry pumps manufacturer casing is removable tray cover or around the slurry pumps manufacturer casing and set up, it may not be used for the whole slurry pumps manufacturer lifting, so as to avoid accidents.

2, from the common base of the motor and harness horizontal slurry pumps manufacturers, lifting the center of gravity close to the square hole in the bracket at the coupling, wire rope which passes through vertically upward with a lifting hook connection, in order to maintain balance, the slurry pumps manufacturer must shell above the eye bolts, eye bolts and lifting hooks motor is disposed between the auxiliary hoisting rope.

3, with coupling and other intermediate transmission slurry pumps manufacturer units shall be horizontal split lifting.

4, slurry pumps manufacturer parts in contact with the wire rope should be padded soft material protection to avoid damage to the slurry pumps manufacturer or cause rope cut appearance.

Maintain

 

EZJ series slurry machine have been adjusted at the factory, users within six months after purchase, without the use of slurry pumps manufacturers do not have to be overhauled. Only checks rotation is flexible, corrosion conditions and circumstances can refuel before use need to fill unfilled.

1. Keep the device clean, dry and free of oil, does not leak.

2. Daily behave within the oil level is appropriate bracket, the correct oil level is near the position of the oil level line shall not exceed ±2mm.

3. Often behave slurry pumps manufacturer operation is abnormal sound, vibration and leakage, identify problems and timely treatment.

4. Prohibited slurry pumps manufacturer evacuated state operation, because the slurry pumps manufacturer is not only taking the time to run under severe vibration, but also affect the life of the slurry pumps manufacturer, be sure to pay special attention.

5. Never enter a metallic object inside the slurry pumps manufacturer and the slurry pumps manufacturer is allowed to pass over the bulk solids, and allowed to enter the rubber, cotton, silk, plastic sheeting and the like flexible material, so as not to undermine the flow components and clogging impeller, the slurry pumps manufacturer does not work.

6. Always check the seal water and cooling water pressure and flow is appropriate, can be checked the valve opening degree water seal or stuffing box temperature detection method described high temperature water supply is insufficient. For lubricated with grease filler slurry pumps manufacturer, every day should be regularly refuel once or twice to ensure that the filler in a good state of lubrication.

7. Periodic testing seal water leakage, when leakage is increased, should be adjusted packing gland bolts, the need for filler should be conducted.

8. Recommended PTFE carbon fiber soaked cotton stuffing or butter to cook, working pressure of not more than 0.5MP a, we can use asbestos packing. Filler filling pressure method shall be strictly in accordance with the following requirements Filling:

(1) Expand the circle packing length sleeve length determined by each ring when filling pressure to cut staggered 120 °.

(2) After filling pressure, must be carried out through the water commissioning, operation detail when adjusting gland bolts, to leak into the status of the line point and is not the best. Filler filling pressure is very important, it is not only related to the sealed state is good or bad, but also affect the performance of the slurry pumps manufacturer, which should be sufficient attention.
