Metal Lined Slurry Pump Factories Trend Report

Common knowledge of disassembly and assembly and installation of slurry pumps is a common knowledge that users must know. In order to facilitate everyone to understand and use this type of product, today the editor has edited and summarized some common knowledge of disassembly and assembly and installation of slurry pumps.　　1. Common knowledge about slurry pump disassembly 1. Disassembly and assembly of the pump head part: The disassembly and assembly and clearance adjustment of the pump head part should be carried out in accordance with the diagram. The impeller, sheath, rear guard plate, and sealed box are all equipped with lifting tools for disassembly and assembly (lifting tools need to be ordered separately to purchase).2. Shaft seal part: The disassembly and assembly of the filler shaft should be carried out in accordance with the drawing. In order to ensure the sealing effect of the filler shaft seal, the shape of the filler opening should be cut as much as possible as possible as possible as possible as possible. When loading into the filler box, the openings of the adjacent filler should be staggered by 108 degrees.　　2. Maintenance is one of the very important things. Here is a very important matter. The maintenance of the slurry pump is introduced to you: 1. The bearing water pressure and water volume must meet the regulations. Adjust the tightness of the filler at any time and do not cause the shaft seal to leak slurry.And replace the sleeve in time.2. When replacing the bearing, be sure to ensure that the bearing assembly is free of dust and the lubricating oil is clean. The bearing temperature is generally not exceeding 60-650C when the pump is running, and the maximum is not exceeding 750C.3. Ensure the coaxiality between the motor and the pump, ensure that the elastic pad in the coupling is complete and correct, and should be replaced in time after damage.4. Ensure that the pump components and pipeline systems are installed correctly, firmly and reliably. 5. Some components are consumable parts. In daily use, pay attention to the loss of consumable parts and repair or replace them in a timely manner.During the repair or replacement of consumable parts, it is necessary to ensure that the assembly is correct, the clearance is adjusted reasonably, and to avoid the occurrence of tight friction.6. The suction pipeline system must be free of air leakage. At the same time, pay attention to whether the suction inlet is blocked during operation.The medium required for the slurry pump is mostly solid particles, so the barrier placed in the pump tank should meet the requirements of the particles that can pass through, reducing the possibility of excessively large particles or long fiber materials entering the pump body and causing clogging.3. Installation and use knowledge　Slurry pumps are widely used in chemical industries such as petrochemicals, coal chemicals, etc., transport liquids of different properties and provide the pressure and flow rate required for chemical reactions.There are many types, and according to the properties of the conveying medium, they can be divided into acid pumps, alkali pumps, clean water pumps, mud pumps, etc.The working temperature and working pressure of the conveying medium are different, so it effectively extends the service cycle and reduces the amount of maintenance, which plays a great role in improving the economic benefits of the factory.1. Selection and installation The slurry pump should be selected according to the liquid conveyed, and the required performance should be checked, the suction and discharge conditions should be analyzed, whether it is intermittent or continuous operation, etc.Usually operated under pressure and flow conditions close to the manufacturer's design.The following review should be conducted during installation: (1) The size, position and elevation of the foundation should meet the design requirements, the anchor bolts must be properly and correctly fixed in the concrete foundation, and the machine should not have any missing parts, damage or rust; (2) According to the characteristics of the conveyed medium, the materials of the main parts, shaft seals and gaskets should be checked if necessary; (3) The correcting work should comply with the provisions of the equipment technical documents. If there is no provision, it should comply with the provisions of the current national standard \"General Specifications for the Construction and Acceptance of Mechanical Equipment Installation Projects\"; (4) All pipelines connected to the slurry pump body, pipe fittings, and the cleaning requirements of lubricating oil pipelines should comply with the provisions of relevant national standards.2. Use The trial operation of the pump should meet the following requirements: (1) The steering of the drive machine should be the same as that of the pump; (2) Inspect the steering of the pipeline pump and the coaxial pump; (3) The fixed connection parts should not be loose, and the specifications and quantity of lubricant added to each lubricating part should comply with the provisions of the equipment technical documents; (4) Parts with prelubricating requirements should be prelubricated in accordance with the regulations; (5) Each indicator instrument should be installedThe full protection device should be sensitive, accurate and reliable; (6) The wheel should be flexible and no abnormal phenomena; (7) The pump body should be preheated before trial operation, the temperature should rise evenly, and the temperature rise should not be greater than 500℃ per hour; the temperature difference between the surface of the pump body and the process pipeline with the inlet of working medium should not be greater than 4090; (8) The slurry pump is equipped with a connecting device to eliminate the influence of temperature rise, and a bypass connection device should be set to provide cooling water source.

The main purpose of tailings slurry pump is to convey slurry in industrial production, chemical industry, electricity, coal, mining and other industries, and to apply slurry pumps.The slurry it processes mainly contains various solid particles, and we need to further understand its use precautions in daily operations.When dealing with mud with more impurities such as sludge, a filter can be installed at the water inlet to reduce the entry of impurities into the pump body, reduce the possibility of pumping, and extend the service life of the mud pump.The slurry pump should not be used for too long.If there is a backup pump, it should work in turn.　　The pump shaft of the tailings slurry pump adopts a large diameter short cantilever design, which is suitable for high power and harsh working conditions.Grease-lubricated cylindrical and conical bearings are placed in a closed cylindrical bracket, with maze-type seals at both ends to ensure the purity of grease, simple structure, reliable operation and easy maintenance.When using a slurry pump, please carefully observe the operation of the slurry pump after turning on the power supply.The slurry output should be continuous and uniform, without vibration, and a horizontal slurry pump can be used after no noise.If it stops suddenly during operation, disconnect the power immediately and check the cause.1. Use a multimeter to check whether the winding of the water pump motor is disconnected. Insulation can be used for measurement of a 500V megohmmeter.When the insulation resistance is below 0.5 megohm, the pump will not be used.2. Remove the filter and rotate the pump shaft to be flexible.If it is not flexible, it should be adjusted before use.3. Check whether the capacity of the slurry pump gate fuse for tailings is appropriate. Other wires cannot be used instead of the fuse.

We have already introduced a lot of slurry pumps before, such as: Can slurry pumps achieve the purpose of energy saving and consumption reduction?If the slurry pump sleeve is worn to this level, it should be replaced.I believe everyone has a certain understanding of it, but you may not know much about its oil drainage methods and steps.　　1. If you want to empty all the oil in the slurry pump box, you can unscrew the oil drain screw plug at the bottom of the box to discharge the oil.2. When the pump discharges oil, the liquid level height should not exceed 30 mm from the top plate of the oil tank to ensure lubrication and cooling of the bearings in the pump.When the volume of the jack working chamber is too large, an additional fuel tank is required.After draining the oil, please make sure 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 engine oil should be replaced, and the oil tank and filter should be cleaned. The oil quality should be tested through visual inspection and laboratory tests.When the quality of the engine oil decreases, the engine oil should be replaced in time.Make sure to clean the oil tank and oil filter at the same time, and if there is metal chips or water in the oil, find out the cause and troubleshoot the problem.4. In a short period of time when the liquid level drops, the bearing will be lubricated with attached oil and splash oil from the plunger spring.The oil filter in the tank and the oil filter under the pump are made of 230 mesh/inch copper wire mesh and are filtered, and the mesh should be cleaned regularly to prevent clogging.During use, the oil temperature in the fuel tank shall not exceed 60 C, and appropriate measures shall be taken to cool if necessary.
