YB series of ceramic hydraulic piston pump selection and use

High-pressure mud transfer and frame filter are the key processes in non-metal production. The mud flows under high pressure and the abrasion is very good. Ordinary pumps can not be used under such working conditions. In order to solve the problem of this process, YB series ceramic hydraulic piston pump produced by Xi'an Whirlpool Machinery Manufacturing Co., Ltd. has the advantages of high outlet pressure, good wear resistance and convenient maintenance. It is the only one that has passed TUV international certification ceramic column Plug pump manufacturers. YB series ceramic hydraulic piston pump was first used in ceramic production to the spray drying tower transmission of mud, and now the production of ceramic spray drying tower does not have a YB series ceramic hydraulic piston pump. At present, the pump is widely used in ceramics, porcelain, non-metallic, chemical and other fields. In order to make everybody choose and use YB series ceramic hydraulic plunger pump better, now the basic selection method is introduced as follows: First, the plunger pump model and classification: The pump is divided into high pressure pump, low pressure high flow pump and variable Pumps, the same specifications are also divided into ordinary pump and anti-corrosion acid pump. High-pressure pump for long-distance or high-altitude slurry delivery; low-pressure high-flow pump for a stable mass of slurry delivery; variable pump is suitable for use with a variety of filter press filter supporting the use of such pumps with the filter density Increasing automatically increases the pressure and reduces flow. Second, the selection of piston pump: YB series piston pump is mainly used for the transmission of ceramic slurry, coal water slurry, kaolin and non-metallic mineral suspension can also be used for mine slurry, food suspension chemical slurry, magnetic Material delivery, transport solids content greater than 70%, variable displacement pump equipped with a filter press with high work and energy efficiency. Selection should pay attention to the following points: 1, to determine the medium conditions, the plunger pump medium is not allowed to appear in large particulate matter, otherwise it will cause work failure, iron pollution requirements of the occasion should use stainless steel plunger pump, acid Or alkaline medium should be used anti-corrosion piston pump; 2, to determine a reasonable flow range, the nominal displacement of the plunger pump model, the selection should be considered appropriate margin range; 3, determine the applicable pressure level, plunger Pump rated pressure can reach 2.0-2.5MPa, with the filter should be used when the variable displacement pump, the slurry should be used low-pressure pump, reducing waste; 4, to determine the above parameters, according to the principle of rather big, according to the standard Model selection YB series ceramic plunger pump; 5, if in doubt, should call the professional manufacturer, professional engineering and technical people to help selection. Third, the use of YB series ceramic plunger pump 1, the installation: the pump on the basis of the correct level, with the ground screw can be fixed  may not need ground screw,, in order to facilitate the replacement of hydraulic oil and flushing mud pipeline, the pump The base should be 10 centimeters above the ground, with drainage ditches around the foundation. 2, the use of the pump: (A), before the start of preparation: Check the fastening of the various components; Check the fuel tank level, the level of the oil tank to the oil scribing shall prevail in summer with N46, winter with N32 Hydraulic oil. High-pressure pump and pump applications above 140 the same type of anti-wear hydraulic oil. Check the pressure gauge range, pressure gauge hydraulic station 0-16MPa, pressure gauge on the air tank should be 0-6MPa range, can not be installed anti. (B), start: open cooling water; closing, open the switch, jog start button, check the motor steering, should be clockwise, must not be reversed. After checking the correct, then start the motor and pump. (C), the operation of regulation: (1), adjust the relief valve can adjust the hydraulic pressure, you can adjust the mud pressure, adjust the pressure relief valve should be back on the lock nut, each open stop without moving relief valve, oil Pressure can not be higher than 12MPa. Note: The pump should be low-load start, if the two pumps alternately, you can stop after the start, without adjusting the relief valve; (2), adjust the position of the two bumper on the carriage, plunger stroke can be adjusted; (3), when the plunger and seal ring wear leakage occurs, the appropriate pressure ring, tightly grout is appropriate, when the pressure ring to the packing box is still contact with the leakage slurry can be sealed ring at the end plus Gasket. In order to ensure that the seal ring and the plunger concentric, the upper end of the pressure ring and the packing box strive to the upper end parallel to the unevenness of not more than 0.5mm; (4) variable pump and filter press with the use of regulation: adjustment method with the operation of regulation 1). When the pump is delivered from the factory, the pressure of sending slurry is set to 2.0MPa. If the pressure of the slurry to be sent is lower than 2.0MPa, adjust the overflow counterclockwise to make the pressure reach the required value when the plunger runs slowly. (D), downtime: (1), press the stop button, the pump stops. (2), stop cooling water. (3), flush with the valve box. 3, pump maintenance and wearing parts replacement: (a), in order to ensure the normal operation of the pump, should pay attention to the following: a, selection of clean high-quality hydraulic oil, the general filter once in January, three months to replace once, After the timely replacement; b, the pump can not start without coolant and work in case of porcelain plunger to prevent the rapid burst of heat and the rubber seal ring heat damage, the water also played the role of flushing the plunger to Extend the life of the plunger and the seal ring; c, the seal ring should not be pressed too tight, leaking slurry is not suitable; d, long-term cold pump to stop the pump, pumping the mud should be exhausted to prevent pump cracking; e, hydraulic system and mud pipeline seal wear should be promptly replaced; f, should make the plunger stroke as long as possible, the piston does not hit the cylinder end cover, commutation agile appropriate; g, when the pressure from the air tank When the mud pressure fluctuation value is more than 0.2MPa, stop the pump, open the following valve, drain the mud, fill the air, if necessary, remove the pressure gauge on the air tank and flush the valve box from the upper port; h, Regular (one week left ) Check and flushing valve casing; I, bladder-type accumulator to be charged after use half as nitrogen or argon, preferably pneumatic pressure 3.0MPa. (B), wearing parts replacement: (1), seal ring: remove the ring screw, manipulate relief valve, the system gradually increase the oil pressure to promote the piston, the use of mud pressure to loosen the seal ring, the column After the plug is lifted, the pump is stopped, the connecting rod of the piston rod and the plunger is removed, the sealing ring is dismounted, the plunger is carefully inserted into the pump body, the upper end of the plunger is surrounded by an extremely thin copper plate, and the sealing ring is mounted , One by one to fasten the screws. (2), the plunger: the method above, until the plunger referred to a higher position to stop the pump, remove the piston rod and plunger coupling screw. Then pull the plunger and packing together to replace the new plunger, one by one to tighten the screws. (3), the pump: remove the fuel tank cap screws, lifting the fuel tank cap  together with the motor , this action must be careful anti-crash oil filter and tubing, remove the suction pump, drain, and then remove the fixed pump Screw, you can remove the pump. Matters needing attention: 1, flush the valve box and replace each of the parts, do not be tight on the top of the rod is tight, no leakage can be; 2, removal of the right cylinder replacement piston striker, it should be noted that the striker must hide Open the lower end of the fuel tank gap (oil communication port), otherwise, can not fill the oil and the piston can not be commutated; 3, the fuel tank should always be kept clean and can not be washed with water lid and manifold; 4, the hydraulic oil to maintain absolute Clean, be sure to regularly check the quality of the oil; 5, after adjusting the pump pressure, generally do not go to adjust the relief valve, otherwise the original system disorder, prone to failure; 6, abnormal sound, Check the source of the problem, repair it.
