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:Operating procedures for measuring pumps
3, discharge pipeline unimpeded.4, the pipeline should meet the positive pressure head, that is, in high flow suction conditions work.5, check the direction of the pump, strictly prohibited reverse.6. Check the oil level in the crankcase compartment. For multi cylinder pumps, check that the oil level has reached the required level.7 、 pump motor static grounding is good, meet the requirements.
Q:The distance from the pump button to the ground
After confirming that the fire pump has started running, issue a command signal to the hydrant button to light the green answer light.
Q:Fire pump control cabinet There are 6 pumps, two indoor fire hydrant pumps, two spray pumps, and two outdoor pumps
Spray pump in addition to remote direct Kai, there are modules to start function, that is, on the cabinet to add control module, bus linkage pump, in addition to the pressure switch, directly pumping function, a total of three functions.
Q:Does vacuum pump oil belong to dangerous goods?
Of flammable substances, but not included in dangerous goods!Does not belong to dangerous goods,
Q:Significance of water pump model ISO50-160
A pump is a machine that transports liquids or pumps liquids. It will be the prime mover of the mechanical energy or other external energy transfer to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids. Pump performance parameters include flow, suction, lift, shaft power, water power, efficiency and so on;
Q:Water pump can not be pumped out, how to maintain water?
The pipe leaks or leaks:The nut may not pinch well when it is installed. If the leakage is not serious, it can be coated with cement or mixed with asphalt oil in the places where the gas leaks or leaks. Temporary repairs can be done with wet mud or soft soap. If the leakage at the joint, you can tighten the nut by hand. The leak is critical and must be re assembled.
Q:What is the pump delivery? What's the difference between years and years?
First of all, as a student majoring in insurance, I strongly condemn the first floor of ignoring practice and trampling on real knowledge!!The insurance industry criticized a lot, but it is required for many people, we should face and try to maintain the healthy development of the industry, the first floor of the insurance you have not done, have no contact with the insurance, insurance, not to dictate the nonsense, more should not be here misleading!
Q:Any center of the pump
Looking forAlignment means the position of the center of rotation of the pump and motor so that they are in the same line.At least three times after the initial installation or after installation:
Q:Because the water pressure of the booster pump is not enough, it can not work automatically. It can only be operated by hand. It is inconvenient to use.
The worst case is that the pump is not automatic when it leaves the factory, and no one can say whose product is 100%.But there may be automatic control of this piece, not debugging (this depends on the specific product manual or manufacturer)
