Extend the life of the stainless steel gear pump

pump

1, Gear pump selection and installation Gear pump should be carried out in ss gear pump manufacturer specification of accordance with the liquid delivery by choice, performance, and check the need analysis of the suction and discharge conditions, is intermittent operation or continuous operation, etc.Usually should be in or near the manufacturer design rules of pressure and flow rate under the condition of operation.When the pump installation should undertake the following review: (1) basic size, location, elevation should meet the design requirements, the anchor bolts must be properly and correctly fixed in the concrete foundation, the machine should not be missing parts, damage or corrosion, and so on and so forth; (2) according to the properties of the pump is conveying medium, when necessary, should check the main parts, shaft seal and gasket material; (3) the leveling of the pump, is to get a job should comply with the provisions of the equipment technical documents, without rules, should be consistent with the current national standard “mechanical equipment installation engineering code for construction and acceptance of the general regulations; (4) all the pipe connected to the pump body, the installation of the pipe and oil pipeline cleaning requirements shall comply with the provisions of the relevant national standards. 2, the use of stainless steel gear pump The test run of electric gear oil pump shall meet the following requirements: (1) the steering should be the same as the pump to drive; (2) find out the pipes and coaxial pump to; (3) all the fixed connection parts should not loose, the lubrication parts filling specification and quantity of lubricant should comply with the provisions of the equipment technical documents;Botou city tai bang the products of the pump valve manufacturing co., LTD (4) there is a requirement for prelubricated prelubricated part should be in accordance with the provisions; (5) the indicating instrument, safety protection devices shall be sensitive, accurate, and reliable; 6. Barring should be flexible, no abnormal phenomenon; 7) should be done before the china hot oil pump in the test run the pump body preheating, temperature rise should be uniform, should not be greater than the temperature of 500 ℃ per hour;Pump body surface and has a working medium import process piping temperature difference should not be greater than 4090; Was set up to eliminate the influence of temperature rise of connection device, bypass connection device to provide cooling water. stainlessRead More…

ss gear pump start-up step

pump

kcb/2cy/ycb model ss gear pump mainly by gear, shaft, pump body and sealing, medium to strong adaptation, so more and more in industrial use it everywhere, but we use KCB stainless steel gear pump for the first time it is important to note a few points, correct operation and use can increase the service life of the gear pump. 1: check whether the turning of the gear pump with the same direction. 2: turn the coupling with the hand, check the rotation is recorded live. 3: used for the first time open the inlet valve filling liquid. 4: then there is read haina brand stainless steel gear pump operation instruction, according to the instruction to use Above hope can bring you some help, share, welcome all customers to our factory to order ss gear pump.

SS Gear Pump Manufacturer | SS Gear Pump Applications

pump

SS gear pump applications   Stainless steel gear pump widely used in chemical industry, food, etc.Vegetable oil can be transferred, chemical raw materials.Models have KCB gear pump, Ycb gear pump, gear pump can transfer of high viscosity liquids (such as asphalt, glue, etc.) At the same time the pump made of stainless steel can also magnetic drive pump, advantage is no seal leakage.Haina pump is ss gear pump manufacturer, has many years of manufacturing experience, we have any requirements, please contact us.

Hot oil pump impeller is introduced

pump

We often see on hot oil pump impeller balance hole, but I don’t know balance hole the size of the number is based on what to order?Impeller to distance to balance hole on the back of the role of the influential? Hot oil pump impeller balance hole is primarily balance of axial force, which is associated with sealing ring gap.We know that heat pump axial force is derived from the differential pressure of impeller front and back cover.Because the former carries oil inlet, botou haina is a complete plane, the area of different pressure is generated by the pressure differential.If the force is not big, the bearing can withstand, could be solved through bearing.When multi-stage pump, or impeller is too large, the axial force is not the bearing, we must take other corresponding axial force balancing mechanism.Such as the balance disc, balancing drum, balance hole, etc.Balance hole has simple structure, convenient processing is a commonly used equilibrium structure.We know that the pressure difference between before and after impeller cover plate, the main influence factor is the front cover for the oil inlet hole, the area is small a piece, so the HouGaiBan must have a sealed chamber, its area is roughly the same as the inlet area (in order to convenient manufacturing, before and after taking ring is the same, you can save a parts).Thus HouGaiBan the balance holes should be sealed room, from the hot oil pump impeller inlet direction, balance hole should be set in the hot oil pump impeller import parts (favorable) liquid.In order to make the machine to receive strength evenly in the impeller, balance hole should be in the same uniform in diameter.Balance hole size, because the flow is mainly the action of the balance holes static pressure, so the balance hole diameter is not big, usually 3 to 5 mm.

Multistage centrifugal pump operation & maintenance

pump,

operation: In the use of stainless steel multistage centrifugal pump, the first to determine the purpose and multistage pump performance parameters and choose the pump type.The principle of multistage pump and basis: 1, make the selected multistage pump type and performance in accordance with unit capacity and head, pressure, temperature, NPSH, the requirement of the process parameters such as suction. 2, multistage pump must meet the requirements of dielectric properties. (1) for conveying inflammable, explosive or toxic or valuable medium pump, require no leakage of pump shaft sealing is reliable or adopted, such as magnetic pump (without shaft seal, driven by magnetic isolation type indirect); (2) the multistage pump forhandling corrosive mediums, convection components with corrosion resistance materials, such as fluorine plastic corrosion pump; (3) for conveying multi-stage pump, containing solid particles medium for convection part adopts wear-resisting material, use clean liquid wash shaft seal when necessary. 3, mechanical aspects of multistage pump of high reliability, low noise, small vibration. 4, correct calculation of multistage pump procurement costs, including purchasing cost and maintenance cost. maintenance: (1), check whether there is any loose phenomenon on multistage pump pipe road and the junction.Turn the multistage pump with the hand, and proved the multi-stage pump is flexible. (2), the bearing body join bearing lubrication oil, should observe the oil level in oil mark the centerline, lubricating oil should be timely replacement or supplement. (3), unscrewed the multistage pump pump body of water diversion plug, water perfusion (or plasma). (4), close out of the water gate and export of pipeline pressure gauge and imported vacuum gauge. (5), the motor running, and proved the motor steering is correct. (6), multi-stage pump stopped for a long time, the pump must be opened entirely, dry the water, will turn the parts packed and junction coated with grease. (7), try to control the capacity and head of the multistage pump, within the scope of the specified on the sign to ensure that the multistage pump running at peak efficiency, to achieve maximum energy saving effect. (8), multi-stage pump in the process of operation, bearing temperature cannot exceed environment temperature to 35 c, the highest temperature should not exceed 80 c. (9), in case of abnormal sound of a multistage pump should immediately stop check. (10), multi-stage pump to stop using, first close the gate valve, pressure gauge, then stop the motor. (11), multi-stage pump in the first monthsRead More…
