◊ Technical data

Q: Working principle and diagram of axial piston pump with pressure compensation variable: Working principleThe main part (see section structure) the transmission shaft drives the rotating cylinder, the plunger seven uniform distribution on the cylinder to rotate around the shaft center line through the center of the spring will be slippery boots column components in the variable pressure in the head (or swash plate). In this way, with the rotation of the plunger cylinder for reciprocating motion complete, oil absorption and oil pressure action.

Q: How about the depreciation of vacuum pumps?: (three) appliances, tools, furniture and so on related to the production and operation activities, for 5 years;(four) aircraft, trains, ships and other means of transport for 4 years;

Q: What are the important parameters of the pump?: Mass flow is expressed in Qm units: t/h, kg/s, etc.The relation between mass flow and volume flow is:Qm= P QIn the p - type liquid density (kg/m3, t/m3), room temperature water P =1000kg/m3.Lift H

Q: Variable flow pumps are variable pumps: Yes. The variable pump is designed to change the flow rate

Q: What is the pump, how to classify, mainly used in where?: 1. vane pumpThe impeller pump is driven by the impeller to rotate the liquid at high speed and transfer mechanical energy to the transported liquidAccording to the pump impeller and runner structure characteristics can be divided into different:1) centrifugal pump2) axial flow pump3) mixed flow pump4) vortex pumps3. jet pumpA high velocity jet produced by a working fluid is used to eject the fluid, and then the energy of the ejected fluid is increased by momentum exchange

Q: What kind of motor does the hydraulic pump need?: First count the flow: Q=dn L / minD displacement / revN RPM / minThen calculate the actual power: N=QP/ (60K) kwQ flow L / minP MPa MPaK total efficiency (usually 0.85)

Q: Difference between pump and compressor: In the spiral case, the liquid slows down due to the gradual enlargement of the flow passage, and the part of kinetic energy is converted to static pressure, and finally flows into the exhaust pipe at higher pressure and is sent to the required place. When the liquid flows from the center of the impeller to the outer edge, a vacuum is formed at the center of the impeller. As the pressure at the upper level of the tank is greater than the pressure at the pump inlet, the liquid is continuously pressed into the impeller. Visible, as long as the impeller continues to rotate, the liquid will continue to be inhaled and discharged.The working principle of the linear pump is different from that of any other pump. It adopts the principle of magnetic suspension and the hydraulic structure of the spiral ring to realize liquid propulsion, that is, to cancel the shaft, to cancel the shaft connection, and to cancel the sealing structure of the shaft. After starting, the electric current is transformed into a magnetic field, and the magnetic field force drives the spiral ring to move, namely, the spiral ring promotes the liquid advance.Compressor (compressor), a driven fluid machine that promotes low-pressure gas as a high pressure gas, is the heart of a refrigeration system. It is of low temperature and low pressure refrigerant gas suction pipe from the suction, through the operation of the motor drives the piston to compress it after high temperature and high pressure refrigerant gas discharge pipe to the exhaust, to provide power for the refrigeration cycle, so as to realize the compression and condensation (exothermic), expansion and evaporation (endothermic) refrigeration cycle.

Q: What is the difference between centrifugal pump and rotary vane pump? What are the distinctive characteristics or principles of rotary and centrifugal? O (a _ U) O thank you!: Directly said vane pump on the line, generally do not say rotary vane pump.The centrifugal pump is divided according to the direction of the liquid flow in the impeller

Q: What are the parts of a pump? How do you classify it?I just want to know: Before opening the pump suction pipes and pumps must be filled with water. Open the pump, the impeller rotating speed, which leaves the liquid together with the rotation under the action of centrifugal force, the left outside impeller injection, injection of the liquid in the pump shell gradually slow the spread of indoor speed, the pressure gradually increased, and then from the pump outlet. The outflow discharge tube. At this time, in the leaves at the center of the vacuum area of low pressure liquid was thrown to the surrounding formation there is no air and no liquid, liquid pool at the surface of the liquid under the action of atmospheric pressure, through the suction pipe into the pump, the liquid is continuously pumped up from the liquid pool is also continuous outflow from the discharge pipe.Mainly by the impeller, pump shell, pump shaft, bearings and packing sealing devices and other components

Q: Metering pumps related matters: 2) change the metering pump diaphragmTrouble is often encountered when the old diaphragm is removed. Provide some additional advice on how to remove the old diaphragm.After in the pump head loose, remove the pump head before the stroke length adjustment to the 10% position. To ensure that the electromagnetic axis has sufficient pressure to maintain its connection firmly, so that you can unscrew the diaphragm.The pull end torque from the Jack out of the screw. Seize the liquid counter clockwise rotation. There is a slight resistance that can unscrew the diaphragm.Chemical 3 measurement may end in fluid crystallization, resulting in a one-way valve ball and seat valve does not work.In the end inhalation metering pump may have a gas leak. Hydraulic end suction side connector may lack O ring or suction valve connection loose.3) flow monitoring and measurement of a high viscosity medium, in the process of liquid delivery received a flow failure signal, how can we solve this problem?Move the hydraulic end by loosening the 4 pump head screws. Rotating stroke length to 10%, and seize the hydraulic end, and then slide out of the screw hole, then the screws do not touch them, but still control the back and diaphragm. Then rotate the component counter clockwise, with a slight resistance, and the diaphragm will loosen from the electromagnetic axis. If the diaphragm is not loose, use some grease on the contact surfaces of the diaphragm and the electromagnetic shaft. After a few minutes, gently tap the diaphragm with a small plastic hammer. Then proceed again in accordance with the above description.
