Q:Bolus dosage of infusion pumpWhat is the purpose of the pill dose control in the special safety standard for infusion pumps? If the risk is not properly controlled, what is the degree of risk? And how can the open infusion pump be used in this regard?

(1) the pellet dose in the safety standard of the infusion pump refers to the amount of liquid that is transported to the patient in a short period of time(two) pill dose limit is mainly to control the risk of accidental pill dosage. Especially after the mandatory requirements of pipe blockage in the elastic pipe storage liquid limit amount of agglomeration and the limitation of these methods to release pill dose.

Q:What does electromechanical vector pump mean?

It is a close set of mechanical and microelectronic technology. It adopts dual control center mode to control, and has a new water pump with logic control center and IPC control center.

Q:How many kinds of pumps are available and the operating principles of various pumps?

There are many kinds of pumps. There are different classifications according to different standards. If classified according to the principle of work, can be broadly divided into the following four categories:1, vane pumps: centrifugal pumps, axial pumps, mixed flow pumps, vortex pumps, etc.;2, displacement pumps: piston pumps, piston pumps, diaphragm pumps and so on;3, power rotary pump: screw pump, gear pump, etc.;4 、 special function: jet pump, water hammer pump, magnetic drive pump, etc.;

Q:The water tank of the fish tank does not air out and only has the water outlet

The air inlet pipe is connected with the oxygen burst, the entrance also pulled out, we can see that it is the design of a miter, the oblique incision back to the direction of the water flow speed, this outflow, negative pressure is formed in the oblique incision, the air can be sucked in. As shown.

Q:What do you mean by the self coupling device on the pump?

Auto is an installation of the pump, which comprises a pedestal, self coupling frame, a guide rod and a guide rod support, the bottom fixed coupling frame, vertical installation of two guide rods can easily be brought down without installing the pump, the pump at the bottom of the pool, the outlet of the pump and the discharge tube can automatically lock, don't need to bolt connection, automatic coupling position, so as to achieve the effect of simple and convenient. When you need to repair, pump the pump up without jumping into the sink.

Q:What's the difference between non negative pressure and variable frequency water pump?

No negative pressure is superposed pressure intelligent frequency conversion equipment, pump frequency operation is no negative pressure difference, and the variable frequency pump, variable frequency pump is advanced municipal tap water tank or pool, pump from the tank or pond water pressure to set pressure to the pressure water supply, and no negative pressure directly from water the municipal pipeline, using the original municipal 2~3 kilograms of pressure

Q:What are the failures and causes of the replacement of the fuel pump assembly?

Common troubles of gasoline pump:Gasoline pump supply shortage of gasoline pump supply depends on the pump membrane stroke, stroke, pump oil should be more; however, the amount of gasoline pump oil pump will reduce the consumption of gasoline engine, and the fuel pump is inevitable, if the engine fuel consumption, but the actual amount of oil is less, this situation is the amount of oil in the petrol pump, there will be a float chamber of a carburetor oil level is reduced, the engine power shortage.

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.

Q:What are the problems that should be paid attention to when using vacuum pumps?

(1) check the vacuum pump line and the joint site regularly to see if there is any looseness. Turn the vacuum pump by hand and see if the vacuum pump is flexible.(2) add lubricating oil to the bearing body, observe the oil level at the center line of the oil mark, and the lubricant shall be replaced or supplemented in time.(3) plug screw vacuum pump of the water screw, filling water (or lead paste). (4) turn off the gate valve of the water outlet pipe and the outlet pressure gauge and the vacuum gauge. (5) point motor, and see if motor steering is correct.(6) start the motor. When the vacuum pump is in normal operation, open the outlet pressure gauge and the inlet vacuum pump. As soon as the proper pressure is shown, the gate valve is gradually opened, and the motor load is checked.

Q:How long does the fine stone pump need maintenance? What should I pay attention to?

Check the line from the relief valve to the cylinder inlet to ensure that there is no external drainage or deformation due to impact and wear and that the connections are complete and fully tightened. - replace any damaged pipe immediately. - change the original settings strictly: all adjustments and calibrations can only be done by professionals. - no fucks hydraulic components, otherwise manufacturers on product warranties and liability shall not be responsible for. A warning because the hydraulic oil can reach very high temperature, there is the danger of burns, so open pipe fittings should take appropriate protective measures. Any replacement parts must conform to the level specified by the manufacturer. 8.2 check lubrication grease pump in oil at any time to ensure adequate and clean the lubrication pipeline joints without overflow phenomenon. Check the lubrication of the running parts at any time, and find the parts which lack oil, and check them immediately to prevent accidents. - check that the centralized lubrication system is effective daily. When the grease pump is empty, the grease added is often not easy to pump out because of the bubble. In this case, open the outlet of the pump, run the grease pump until the grease is re flowing, and then connect the pipe
