Overview of YZR hot oil pump: YZR submerged thermal oil pump, heavy oil pump, tar pump, coal tar pump is a vertical single-stage, single-suction cantilever centrifugal pump structure, the impeller is a semi-open impeller, There are mixing blades. This series of pump is mainly used in environmental protection, municipal engineering, thermal power plants, gas coking plants, oil refineries, steel mills, mining, paper making, cement plants, food plants, printing and dyeing and other industries suction concentrate, heavy oil, oil Slag, contaminated liquid, mud, mortar, runoff and urban sewage channel flow of sludge, as well as containing sediment fluid and corrosive liquids. Can transport high temperature (480 ℃) of kerosene, crude oil, asphalt, oil residue and other conditions. Pump drive mode: The pump is connected to the motor via a flexible coupling. The pump rotates in a clockwise direction from the direction of the prime mover. Structure Description: YZR-type pump is single stage, single-suction cantilever structure, with the bearing seat, the connection pipe connected to the pump hydraulic components, liquid from the discharge pipe components, pump impeller half open impeller, impeller blade inlet extension There are mixing blades, the pump is characterized mainly in the liquid part of the pump shaft, there is sufficient rigidity, impeller, pump housing without bearings between, without the use of shaft seals, you can transport medium containing a greater depth of solid particles. The length of the pump inserted into the liquid between 800-2000, if necessary, can be equipped with suction pipe. Shaft seal liquid submerged pump into the liquid operation, no shaft seal, the drive motor mounted by the vertical motor support and bearing seat, with the coupling connected to the pump. YZR submerged slurry pump assembly sequence: 1. The bearings were mounted on the bearing box and bearing seat. 2. Felt ring mounted on the bearing cap A, C and bearing box. 3. Install the bearing caps B and C on the bearing housing and fasten them with bolts. 4. Put the bearing box bearing on the shaft, screw on the round nut, and fasten the bearing end cap A on the bearing box. 5. Install the shaft into the bearing housing, fasten it with bolts, screw in the adjusting screw, and install the bearing seat on the bearing seat. Place the retaining ring in place on the lower bearing. 6. Fix the coupling pipe to the bearing seat, install the pump cover under the coupling pipe, install the impeller on the lower part of the shaft and tighten it, install the front cover of the pump body in turn, and fix the bolts with the adjusting screws at the bearing box The gap between the impeller and the front cover, (controlled within 1 ~ 1.5mm) adjusted with a nut, bolt fastening. 7. Motor support installed in the bearing block bolted to the shaft at the top of the shaft coupling components, and the motor coupling fastening screws fastening the motor shaft, the motor mounted on the motor support, and use Bolt, nut fastening. 8. Install the asbestos pad, the elbow, and the liquid pipe assembly in the order of the pump outlet, and fasten the support base. Installation: 1. Installation work before installation a. Check whether the pump and motor are damaged b. Prepare tools and lifting equipment c. Check the foundations according to the drawings 2. Install the pump bearing seat on the container and tighten it with bolts Cement well tank to be set in advance anchor bolts) Start and stop: 1. Observe whether the pump has been installed on the basis of light and light friends, all the bolts are tightened. 2. Check whether the pump axial clearance has been adjusted (pull the coupling without friction sound). 3. Oil standard injection of calcium-based butter 4. Check the motor rotation direction is correct 5. Start the motor, open the pressure gauge cock, when the pump to work at full speed, adjust the valve opening to the desired range. 6. Stop the pump, you should stop the motor, and then close the pressure gauge cock. 7. Pumps to stop running for a long time, the pump should be disassembled, wipe clean, coated with anti-rust oil properly preserved. Maintenance: 1. Note that the temperature of the pump bearings, the outside temperature should not exceed 35 ℃ but the maximum should not exceed 75 ℃. 2. The cup should be filled with calcium-based butter to ensure that the bearing can be lubricated normally. 3. Pump in the first month of work, or after 100 hours of operation, should replace the motor support oil cup butter. After every 2000 hours of work to be replaced once. 4. Regularly check the flexible coupling, pay attention to motor bearing temperature rise. 5. During operation, if any noise or abnormal sound is found, stop inspection immediately. 6. The pump should be checked for a period of 2000 hours of operation. The clearance between the impeller and pump body (or pump cover) should not be too large. The maximum clearance should not exceed 1.5 mm, such as exceeding the replaceable impeller or cover.
