The mortar pump is a kind of pump that can adapt to various working conditions, such as conveying acid, alkaline clear liquid or slurry;
Smelting industry all kinds of corrosive pulp; sulfuric acid industry all kinds of dilute acid; environmental protection industry all kinds of sewage. The pump is resistant to corrosion and wear, the use of a wide range. But we must also understand the mortar pump in a variety of applications will often appear in the fault, mortar pump common fault and solutions.
1): Reasons for rapid pump wear: poor construction conditions (large particles), long walk intervals, and long water inlet pipes. Treatment methods: change the battlefield, add afterburner units, shorten the length of water inlet pipes and reduce cavitation
2): Reasons for fast wear of impeller journal: low lift of high-pressure water pump, misalignment of packing, and treatment of divergence between pump shaft and rear cover: replace high-pressure pump higher than the lift of mud pump, replace packing, and adjust the degree of unity.
3): Cause of water pump vibration: different hearts between pump shaft and diesel engine (or motor), impeller is not balanced, bearing damage treatment method: adjust the consistency, impeller for balance test, change bearing
4): Reasons for low outlet pressure and small flow rate: air in the pump, large gap between the impeller and the front lining plate, tight closing of the separator, abrasion of the impeller or lining plate: evacuate the gas in the pump, adjust the gap, adjust the friction plate gap of the separator, and replace the impeller or lining plate
5): The reason for the slow water supply of the pump: the gap between the front lining plate and the impeller is large, the water outlet pipe cannot seal the air, and the treatment method for emptying the water: conditioning the gap, conditioning the water outlet pipe, and vacuum installation of the device
6): The reason why the pump does not absorb water: the pouring water is not enough, the air in the pump cannot be discharged, the suction pipe leaks, and the gap between the front lining plate and the impeller is large. Treatment method: continuously infuse the water diversion, reflect on whether the pipeline can leak, and adjust the clearance between the impeller and the front lining plate.
