How to adjust the pressure switch of household towerless water supply

Use mechanical pressure switch: open the pressure switch plastic shell, there are two large and small spring columns and a large spring column inside, if you need to adjust the pressure, tighten the screws on the large spring column clockwise, and loosen the screws on the large spring column if you need to lower the pressure.

Electronic control cabinet supporting pressure gauge: The pressure gauge used with the control cabinet is an electronic contact pressure gauge, and the high-pressure pointer and low-pressure pointer can be adjusted respectively by pressing the adjusting spring up and down the gauge hand.

Determine the standard pressure value required?

The method is as follows: when adjusting, open the faucet that is the farthest and highest distance from the towerless water supply, and constantly check the water pressure of the faucet according to the progress of adjustment until the water outlet pressure meets the demand, and the towerless water supply device can automatically stop working, and before the next start, the faucet water can still meet the pressure requirements as the best.

The towerless water supply device is to detect the pressure tank pressure through the pressure sensor, and the pressure electrical signal is identified and amplified by the automatic control circuit to control the action of the contactor, so that the water pump can automatically run and stop according to the pressure change in the pressure tank, so as to achieve the purpose of automatic water supply. The working process of the towerless water supply device is that the pump starts, and the water is injected into the pressure tank through the check valve, so that the pressure in the tank increases, and when the pressure reaches the upper limit of the set pressure, the pressure automatic controller automatically closes the water pump and stops the water pump. When the pressure decreases to the lower limit of the set pressure, the pump is automatically controlled to start, and water is automatically injected into the water supply tank, so that the towerless water supply device does not stop supplying water and runs automatically.

Equipment definition] The towerless water supply device detects the tank pressure through the pressure sensor, and the pressure electrical signal identifies, amplifies and controls the contactor action through the automatic control circuit, so that the water pump can automatically run and stop according to the pressure change in the tank, so as to achieve the purpose of automatic water supply. Tower-free water supplyThe tower-free water supply device is to detect the pressure tank pressure through the pressure sensor, and the pressure electrical signal is identified and amplified by the automatic control circuit to control the contactor action, so that the water pump can automatically run and stop according to the pressure change in the pressure tank, so as to achieve the purpose of automatic water supply. The working process of the towerless water supply device is that the pump starts, and the water is injected into the pressure tank through the check valve, so that the pressure in the tank increases, and when the pressure reaches the upper limit of the set pressure, the pressure automatic controller automatically closes the water pump and stops the water pump.

When the pressure decreases to the lower limit of the set pressure, the pump is automatically controlled to start, and water is automatically injected into the water supply tank, so that the towerless water supply device does not stop supplying water and runs automatically.

There are adjusting screws on it, and it is screwed down when pressurized.

Regulate household automatic towerless water supplyPressure valves, unscrew the fixing screw of the pressure valve cover, and take off the cover of the pressure valve, the specific operation steps are as follows:

1. Unscrew the fixing screws of the pressure valve cover.

2. Take off the cover of the pressure valve.

3. The nut on the large spring is to adjust the pressure of the pressure valve.

4. Use a wrench.

Twisting the adjusting screw in the direction of the arrow increases the pressure of the towerless water supply.

5. Use a wrench to twist the adjusting screw in the direction of the arrow to reduce the pressure of the towerless water supply.

6. After the adjustment is completed, install the cover and the operation is completed.

The required pressure is the key to Woodson's judgment that the pressure switch is working properly or not, so how should we make a reasonable judgment in this situation? Is the pressure switch broken, or is the pressure not yet at the pressure value set by Chunyinda? 3. If the pump continues to supply water to the towerless water supply, the pressure gauge value should be carefully checked, assuming that after the pressure gauge arrives, the pump continues to work, and the pressure switch is still not power-off.

4. Judgment: Turn off the power supply, open the plastic cover of the pressure switch of the tower-free water supply equipment, tighten the adjusting spring screw clockwise, then restart the power supply, start the second round of testing, and still follow the above steps. Assuming that the pressure switch is de-energized when the pressure value is reached, then it is possible to determine the pressure of the pump and the pressure that can only be achieved by the head.

If this pressure value is not enough for us to use normally, then the pump can only be replaced; If the pressure switch does not work properly after adjusting the pressure (below or more) several times, the pressure switch should be replaced in time.

The high spring is the starting pressure, and the low spring is the de-energizing pressure. Clockwise.

Upward adjustment is an increase in pressure and a decrease in downward pressure. In the process of adjustment, it must be adjusted in a small amount, and the range of positive and negative adjustment is: small grids). Large and non-standard adjustments can lead to pressure switches.

Malfunction. When the pressure reaches the specified limit, the contact pressure gauge.

Or the pressure switch stops the pump automatically via the control cabinet. The water pressure in the equipment is higher than the outside pressure and is automatically sent to the water supply network.

When the pressure in the tank drops, the water level drops to the specified limit, the electric contact pressure gauge or pressure switch restarts the pump through the slag control cabinet, and so on, so that the equipment does not stop supplying water, and when the tank energy gas drops, the pump starts.

Method: 1. Use a mechanical pressure switch: open the pressure switch plastic case, there are two large and small spring columns and a large spring column inside, if you need to increase the pressure, tighten the screws on the large spring column clockwise, and if you need to lower the pressure, the screws on the large spring column will be loosened.

2. Electronic control cabinet supporting pressure gauge: The pressure gauge used with the control cabinet is an electronic contact pressure gauge, and the adjusting spring is operated before pressing the gauge needle up and down, which can adjust the high-pressure pointer and low-pressure pointer respectively.

How do I determine the standard pressure value I need?

The method is as follows: when adjusting, open the faucet that is the farthest and highest distance from the towerless water supply, and constantly check the water pressure of the faucet according to the adjustment progress until the water outlet pressure meets the demand, and the towerless water supply device can automatically stop working, and the faucet can still meet the pressure requirements before the next start.

If the pressure switch of the water supply without a tower does not jump, the following situations may occur: 1The pump did not start:

Check whether the pump is connected to the power supply, whether the power supply is normal, and whether the fuse is damaged or blown out. 2.Insufficient water or clogged pump inlet:

Check that the water source is sufficient and that the pipes are not leaking or clogged. 3.Pump Damage:

Detect whether the motor rotor and impeller of the pump are stuck or worn, and replace them if necessary. If none of the above three conditions exist, the pressure switch itself needs to be checked. You can troubleshoot by following these steps:

1.Lift the red rod under the pressure switch with your hand and press the red button at the same time, observing the position of the rod and the spring behind the volute, the rod should return to its original position and trigger the spring to pop up. 2.

If the pressure switch fails, the part needs to be replaced. Before replacing, make sure to unplug the power cord from the socket and follow the instructions. 3.

Hello, the above questions will be answered by me. How to deal with the pressure switch of the towerless water supply that does not jump If you find that the pressure switch of the towerless water supply does not jump, you can try the following methods:1

Check whether the water source is unobstructed: First check whether the water source is unobstructed and whether there is any leakage in the water source pipeline to ensure that the operation of the water pump is not affected. 2.

Check the inlet and outlet of the pump: Check the inlet and outlet of the pump for blockages and blockages, and remove the blockage of the inlet and outlet of the pump. 3.

Check the pressure switch: check whether the pressure switch is working properly, whether there is a "stuck" or "top" phenomenon when turning the handle, and remove the foreign matter in the pressure switch. 4.

Adjust the pressure switch: adjust the lower pressure to the starting pressure of the pump, and the upper pressure to the parking pressure of the pump. 5.

Check for leaking water pipes: Check whether the pipes are leaking, whether the joints are tight, and if there is a need to repair them. If none of the above methods solve the problem, it is recommended that you ask the pump maintenance personnel to troubleshoot and repair.

At the same time, it is necessary to comply with the operation specifications in the manual of the production sail next to the sail, maintain the pump equipment, and avoid the damage of the pump and the unnecessary economic damage caused by the loss. Hope it helps!
