How to use Shijiazhuang slurry pump correctly

Slurry pump is a commonly used equipment in mineral processing, which is mainly used for slurry transportation. Many people do not know how to operate the slurry pump, so that improper use of the slurry pump may affect the normal operation of the slurry pump and its production capacity. In severe cases, the equipment may not be used, affecting the work efficiency. What problems are easily caused by improper use of slurry pump, and how to solve them to make the slurry pump work normally? 1. Long-term use of slurry pump will cause scaling on the surface of cooler pipe and poor heat transfer; Less cooling water or no cooling water. Therefore, always check whether the pressure and flow rate of bearing cooling water are appropriate. General slurry pump cooling water pressure is 0.05 ~ 0.2 MPa, cooling water flow rate is 1 ~ 3 m3/h. Replace the fouling cooler in time and start cooling before the pump starts. Adjust the pressure to the specified value with water, and regularly check the bearing temperature rise (35℃), and the high temperature shall not exceed 75℃. 2. The packing wear during the use of slurry pump leads to seal failure. Slurry leaks along the shaft seal. The slurry instantly fills the curved surface of the semicircular positioning hole connecting the bracket and the rear pump shell, and the slurry discharged from the discharge port has no time to pass through the plug. . The seal at the water pan penetrates into the oil pan, resulting in bearing damage. In daily maintenance, attention should be paid to regularly checking the leakage of shaft seal. When the leakage increases, the packing gland bolts should be adjusted, and the packing and the failed O-ring seals should be replaced in time to prevent the slurry from leaking along the shaft from the water baffle. Infiltrate into the oil groove of the bracket. 3. Unclean lubricating oil causes problems such as bearing friction, wear, heat and vibration. Lubricating all parts of bearings can reduce friction and wear. The quality of lubricating oil should be checked regularly to avoid dust or deterioration of oil products. Lubricating oil should be adjusted in strict accordance with the operating instructions of the pump. It shouldn't be too much or too little. If there is too much oil, it will not take away most of the friction heat inside the bearing, nor provide effective heat dissipation, which will increase the temperature of the bearing; If the amount of oil is too small, it will lead to oil film rupture and dry friction of the bearing, which will burn the bearing. These minor problems of slurry pump will have a great impact with the passage of time, so it is necessary to check and repair them in time to ensure the normal use of slurry pump.
