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, the basic selection method is introduced as follows: First, the type and classification of plunger pump The pump is divided into high pressure pump, low pressure high flow pump and variable pump , 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 Of the delivery, delivery of solid 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 anti-corrosion piston pump should be used; 2, to determine a reasonable flow range, the nominal displacement of the plunger pump model is the flow rate, 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 will be placed on the basis of the pump, the level of calibration, with the ground screw can be fixed î—¤ may not have ground screws, to facilitate the replacement of hydraulic oil and flushing mud lines, the basis of the pump Should be 10 centimeters above the ground, there should be drains 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 window engraving shall prevail in summer with N46, N32 in winter with 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) operation adjustment: (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 the relief valve, hydraulic pressure may not Higher than 12MPa. Note: The dosing pump should be started at a low load. If the two pumps are alternately used, they can be stopped after starting without adjusting the relief valve. (2) The position of the two bumpers on the carriage can be adjusted to adjust the plunger stroke. 3) When the plunger and seal ring wear leakage occurs when the squeeze ring properly adjusted, tight to no leakage is appropriate, when the pressure ring to the packing box is still leakage slurry contact, the seal ring can be added to the top of the gasket . In order to ensure that the seal ring is concentric with the plunger, the upper end of the water pressure ring should be parallel with the upper end of the packing box, and the roughness should not be more than 0.5mm. (4) Adjustment when the variable displacement pump and filter press are used: ). 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) down (1) Press the stop button, the pump stops. (2) stop cooling water. (3) Wash the valve box with water. $$ Div $$ 3, pump maintenance and replacement of wearing parts: (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 Replace once, metamorphism and timely replacement; b, the pump can not start without coolant and work, to prevent the porcelain plunger chill and heat burst and the rubber seal ring heat damage, the water also serves to flush the plunger Of the role to extend the life of the plunger and seal ring; c, the seal ring should not be pressed too tight, leaking slurry is not appropriate; d, long-term cold pump stop the pump, the pump should be drained to prevent F, the piston stroke should be as long as possible to piston does not hit the cylinder end cover, commutation agile appropriate; g, when from Air tank pressure gauge to see the mud pressure fluctuations greater than 0.2MPa, you must stop the pump, open the following valve, drain the mud, fill the air, if necessary, remove the pressure gauge on the air tank, flushing valve from the upper port box ; H, regularly (about a week) check and flush the valve box; i bladder accumulator should be filled with nitrogen or argon six months after the use of inflation pressure of 3.0MPa is appropriate. (B) replacement of wearing parts: (1) seal ring: remove the clamp ring screw, manipulate the relief valve, the system gradually increased oil pressure to promote the piston, the use of mud pressure to loosen the seal ring, the plunger lift After the pump is stopped, the connecting screw of the piston rod and the plunger is removed, the sealing ring is removed, the plunger is carefully placed in 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 Tighten the screws. (2) Plunger: Same as above, stop the pump when the plunger refers to a higher position, and remove the connecting rod of the piston rod and the plunger. Then pull the plunger and packing together to replace the new plunger, one by one to tighten the screws. (3) Oil pump: Remove the cap of the fuel tank cap and lift the cap of the fuel tank together with the motor. This action must be careful to prevent the oil filter and tubing from being damaged. Remove the suction and discharge pipes on the pump, and then remove the screw that fixes the pump , You can remove the pump. [Note]: Flushing the valve box and replace each of the parts, do not be too tight on the top of the rod, no leakage can be; remove the right cylinder replacement piston on the pin, you should note that the pin must escape the cylinder The lower cover of the gap (oil communication port), otherwise, can not fill the oil and the piston can not be commutated; part of the fuel tank should always be kept clean, can not be washed with water lid and manifold; hydraulic oil to be absolutely clean, be sure to regularly check The quality of the oil; After adjusting the pressure of the pump, generally do not go to adjust the relief valve, otherwise the original system disorder, prone to failure; abnormal sound, should immediately shut down, check the source of the fault, repair it.
