Slurry pumps can be widely used in mines, electric power, metallurgy, coal, environmental protection and other industries to transport slurry containing abrasive solid particles. It is one of the indispensable equipment in various processes of mineral processing and coal preparation plants. Its basic structure is composed of impeller, pump casing, pump shaft, bearing and bracket. The power also includes motor, counter wheel or belt pulley coupling, etc. The wear-resistant parts also include liner sleeves, etc. The seals include shaft seals, The auxiliary impeller, etc., and the supporting parts include brackets, etc.
Some little knowledge about the oil discharge of the slurry pump
1. If you want to drain all the oil in the slurry pump box, you can unscrew the oil drain plug at the bottom of the box to drain the oil.
2. When the pump discharges oil, the liquid level is not more than 30mm from the top plate of the oil tank to ensure the lubrication and cooling of the bearings in the pump. When the volume of the jack working chamber is too large, an additional oil tank is required. After draining the oil, please ensure that the liquid level is very low and the height is not less than 100mm to avoid oil absorption.
3. After the speed-regulating slurry pump starts to run for 500 hours, the oil should be changed, and the oil tank and filter should be cleaned. Oil quality should be tested by visual inspection and laboratory tests. When the quality of the oil decreases, the oil should be replaced in time. Make sure to clean the fuel tank and oil filter at the same time. If there is metal shavings or water in the oil, find out the cause and eliminate the fault.
4. In a short time when the liquid level drops, the bearing will be lubricated by the attached oil and splash oil of the plunger spring. The oil filter of the oil tank and the oil filter under the pump are made of 230 mesh/inch copper wire mesh and are filtered. The filter should be cleaned frequently to prevent clogging. During use, the oil temperature in the oil tank must not exceed 60°C, and appropriate cooling measures should be taken if necessary.
