Product model: houndreds types product as like GCK
Product features: has high and low voltage switch cabinet put oneself in another's position of equipment are all made of high quality cold-rolled steel plate compound and into, or use the standard assembly components, can absorb a certain amount of mechanical stress, the electric stress and thermal stress, can also withstand normal use may have been wet, the influence of processing flat with no burrs, welding smooth and beautiful, no welding wear and cracks.
Filled with handcart and drawer structure switch device, the handcart push-pull operation is flexible and drawer, no stuck phenomenon.
Cardiac surface treatment according to user requirements can be plastic spraying, spray, spray paint and other craft, surface treatment before to deal with the rust, decontamination and phosphating process.All equipment of front and side coated layer, no wrinkles, scratch, bubble, pinhole, defects such as color, colour and lustre is uniform.

- Q:Frequency constant pressure water supply control cabinet can not pressure switch
- Through the above analysis can be concluded: electrical contact pressure gauge can not achieve a true closed-loop constant pressure water supply. Only through the control circuit through the water pump in the set pressure limit and the upper limit between the repeated start to stop the water supply, while the pipe network pressure in the set upper limit pressure between the lower limit. Electric contact pressure gauge control damage: repeated start and stop the inverter pump water supply system instability, the equipment wear is relatively large, can not achieve constant pressure water supply energy saving effect.
- Q:Pressure switch on a pair of normally open point how to reach the alarm and direct Kai pump
- The current pressure switch directly open pump generally have the following two ways: 1, the project no alarm system, only the sprinkler system, then the pressure switch control line only need to take the spray control in the passive contact. 2, if the alarm system, the pressure switch must both alarm to the alarm host should also start the spray pump, specifically now two methods: A when the single-contact pressure switch, to add an intermediate relay , Then need 24V power supply, through the relay, a route to the spray pump control cabinet, another way to the alarm host.
- Q:1, the pressure switch and the flow indicator alarm with the control room through the host (automatic) to start the spray pump? If so, the three modules is not set in the host between the logical relationship? 2, the fire occurs, the general is waiting for the pressure switch action automatically start the spray pump, or the central control room to start manually, it is in the central control room between the straight panel is what is the relationship between?
- When a fire occurs, the shower head blasting, water flow indicator action, the pressure switch action, the feedback signal back to the host, the host linkage Kai spray pump. When the host is in the linkage state, the pressure switch is generally the action, but can not start the pump, the artificial hard to start the spray pump
- Q:Is the booster pump pressure switch available at the repair shop?
- Directly looking for aftermarket? Responsible for the sale of units are generally sales units.
- Q:Automatic self-priming pump pressure switch how to tune
- It should be automatic pressure control switch is broken, for a will be good, my family is the case! My home switch is very easy to bad, really headache, check and find out what the problem
- Q:Pressure switch and electromagnetic valve operating principle
- what! Upstairs that is too professional, it is necessary to design these devices to understand the talent. Popular pressure switch is quite a button switch is only the power of your original finger on the pressure we need to test to complete the need to complete. Electromagnetic commutation method, but in this it is provided by the external device to control the power to complete, and perhaps this control device is said before the pressure switch.
- Q:Wet alarm valve, pressure switch reported fire, the template lights red, display input action, pressure 0.8, spray pump pressure 0.7,
- And the water flow out of the valve after the flow to the bypass of the water pressure and flow larger, can make the pressure switch, alarm bell alarm. And the end of the water discharge device is 25 of the tube, when the water flow is relatively small, if the water time is short, wet alarm valve to open a short time, from the constant pressure pipe to add water into the sprinkler system before and after the pressure quickly balanced , So that the wet alarm valve closed, bypass the flow of water pressure and flow are very small, coupled with the role of the delay device, which can not reach the pressure switch and alarm action, alarm requirements, the greater the easier spray system This is the case because the capacity in the sprinkler system is large.
- Q:How to determine the car air conditioning pressure switch is good, or bad? What are the steps and methods of operation?
- Then take the table to see if there is no system pressure 0.5M, if any, directly with a multimeter Ohm file pressure switch off the situation, no resistance is good, there is bad ? The answer was
- Q:The master of the dry bottle next to the pressure switch plug in the two lines connected to what is the meaning?
- This maintenance method can be used, if the pressure switch is broken, short circuit is no problem. This can save freon, or else switch to have to re-fill.
- Q:How to switch the pressure switch
- You that is a contactor? Connect the map of the upper end of the power supply under the terminal device, you pay attention to see if the control circuit is 220 or 380
