What is a non automatic hot and cold water booster pump

It is not an automatic water heater booster pump.

Booster pump: booster pump, as the name suggests, is a pump used for pressurization, and its main uses are water heater pressurization, low water pressure in high-rise buildings, sauna and bathing, pressurization of insufficient water pressure on the top floor of the apartment, solar automatic pressurization, reverse osmosis water purifier pressurization, etc.

How the booster pump works:

First, the booster pump is filled with liquid, and then the centrifugal pump is started, the impeller rotates rapidly, the blades of the impeller drive the liquid to rotate, and the liquid flows to the outer edge of the impeller by inertia when rotating, and the impeller sucks the liquid from the suction chamber at the same time, in this process, the liquid in the impeller flows around the blades, and the liquid acts on the blades in the flow movement, and in turn the blades act on the liquid with a force equal to the size of the lifting force and the opposite direction, and this force does work on the liquid, so that the liquid gets energy and flows out of the impeller. At this time, the kinetic energy and pressure energy of the liquid increase.

The gas-liquid booster pump works similarly to a pressure booster, exerting a very low pressure on a large diameter air-driven piston, and when this pressure is applied to a small area of piston, a high pressure is generated. With a two-position, five-way pneumatic directional valve, the booster pump is able to operate continuously. A high-pressure plunger controlled by a check valve continuously discharges the liquid, and the outlet pressure of the booster pump is related to the air drive pressure.

When the pressure between the drive section and the output liquid section reaches equilibrium, the booster pump stops running and no longer consumes air. When the output pressure drops or the air-driven pressure increases, the booster pump will automatically start running until the pressure equilibrium is reached again.

A single pneumatic unbalanced gas distribution valve is used to realize the automatic reciprocating motion of the pump, and the air drive part of the pump body is made of aluminum alloy. The wetted part is made of carbon steel or stainless steel according to the different mediums. Generally, the pump has two ports, inlet and exhaust, and the air inlet can produce air pressure lower than the atmospheric pressure (that is, atmospheric pressure) called "negative pressure"; The air pressure that can be generated at the exhaust port is higher than the normal pressure, which is called "positive pressure"; For example, the vacuum pump is a negative pressure pump, and the booster pump is a positive pressure pump.

A positive pressure pump is very different from a negative pressure pump. For example, in the direction of gas flow, the negative pressure pump is where the external gas is sucked into the suction nozzle; Positive pressure is ejected from the exhaust nozzle; For example, the level of air pressure, etc.

The fully automatic household booster pump does not need to be manually controlled by the power switch.

The fully automatic booster pump can work automatically under the set pressure, and start when the pressure is lower than the set pressure, and automatically increase the pressure.

Non-automatic booster pumps need to be manually activated to increase the pressure.

There are three ways to adjust the pressure switch of the automatic hot and cold water self-priming booster pump:

1. The inlet pipeline is not well sealed, resulting in air being sucked into the pumpCheck the fitting and seal the fitting.

2. The mechanical seal of the automatic self-priming pump for hot and cold water is broken, there is air sucked in from the seal, in which case a new mechanical seal needs to be replaced.

3. The inlet water level is too low to exceed the effective suction range of the hot and cold water self-priming pumpIt needs to be controlled within the effective suction range of the self-priming pump and try to control it within 6 meters.

Machinery purchase. To measure the performance of the pump, the power is not important, but the efficiency of the unit. In the case of the same head and the same flow, the efficiency of low power is high, that is to say, the performance is good.

The pump has the highest head flow and the rated head flow labeling method, most of the pumps on the market are marked with the highest head flow, some manufacturers of pumps are outrageous, such as ordinary 90w and 120w copper pump head booster pumps, the standard power is 80w (up to 10 meters) and 120w (up to 13 meters).

In order to achieve good sales, some merchants change to 100W (maximum head 12-15 meters) and 150W (maximum head 15-20 meters), and the flow rate is also high and scary. There is also a self-priming water pump, the theoretical suction lift is 10 meters, due to the existence of the pump NPSH (the phenomenon of water vaporization caused by roughness in the manufacture of the pump head), the effective suction lift of the self-priming water pump is meters.

There are three ways to adjust the pressure switch of the automatic hot and cold water self-priming booster pump:

The first is that the inlet pipeline is not well sealed, resulting in air being sucked into the pump, check the pipe joint and seal the joint well.

The second is that the mechanical seal of the automatic self-priming pump for hot and cold water is broken, and air is sucked in from the seal, in which case it is necessary to replace the new mechanical seal.

The third is that the inlet water level is too low to exceed the effective suction range of the hot and cold water self-priming pump, which needs to be controlled within the effective suction range of the self-priming pump and controlled within 6 meters as much as possible.

This is not the business of the booster pump, the fault is in the hot and cold mixing valve, it is through it to adjust the proportion of hot and cold water to achieve the required water temperature. It would be nice to change the hot and cold mixing valve.

You have to ask the seller of solar water heaters.

<><1. Is the tap water booster pump automatic?

There are usually two kinds of tap water booster pumps, one is manual, that is, the opening and closing of the booster pump are realized manually, and the other is that after automatic starting, the operation is terminated when the output pressure reaches a certain value, and it starts by itself when the pressure is reduced to a certain value, and the latter is mostly used nowadays. The tap water booster pump will also vary according to the power, head and flow rate.

It is worth noting that tap water booster pumps are usually not used alone, after all, it is impossible for a single pump to meet the function of automatic water supply. To meet the requirements of automatic water supply, it is necessary to combine the necessary spare parts combination such as check valves, sensors and pressure stabilizing tanks.

Second, the characteristics of tap water booster pump

1. Simple maintenance:

Due to the small number of parts and seals in the tap water booster pump, it is easy to maintain and relatively inexpensive.

2. Cost-effective:

The tap water booster pump is characterized by high output and low cost.

3. Strong adjustability:

The output pressure and flow rate of the tap water booster pump are adjusted by the pressure adjustment valve of the drive air. Adjust the driving air pressure, so that the output pressure of the air pressure tube booster pump is accurately adjusted between the pre-increase air pressure and the maximum output pressure.

4. High output pressure

The operating pressure limit of the pneumatic liquid tube booster pump can reach 700 MPa, and the operating pressure limit of the pneumatic gas tube booster pump can reach 300 MPa.

5. Excellent material:

The high-pressure part of the booster pump is made of hard aluminum alloy, and the high-pressure plunger is made of stainless steel, and double-layer sealing is used, and the materials used in key parts can be selected according to the characteristics of the medium.

The difference between automatic and non-automatic household booster pumps is: different control, different starts, and different water shortage protection functions.

First, the control is different.

1. Household booster pump automatic: Household booster pump is automatically controlled by infrared light sensor, which is easily affected by external light and greatly affected by the environment.

2. Household booster pump is not automatic: Household booster pump is not automatically controlled by direct pressure sensing, which is correct and unbiased, and is less affected by the environment.

Second, the startup is different.

1. Household booster pump automatic: The household booster pump can not be started automatically under low pressure, and the pressure difference between the upper and lower limits needs to have an obvious pressure difference.

2. Non-automatic household booster pump: Non-automatic household booster pump can also be stably controlled and started under low pressure.

Third, the water shortage protection function is different.

1. Household booster pump automatic: Household booster pump automatically has water shortage protection function, and can automatically recover after water shortage.

2. Household booster pump is not automatic: Household booster pump is non-automatic and does not have water shortage protection function, and it needs to be manually restored after water shortage.

The difference between automatic and non-automatic household booster pump is that the automatic type has a switch to detect the water flow, start the pump when there is a water flow passing, turn off the pump power when there is no water passing, and the non-automatic one is, of course, turn on the power supply and keep running.

Generally, the automatic booster pump is two methods, one is controlled by a flow sensor, the flow sensor is a valve form, when the faucet is opened, the water in the water pipe has flow, flush open this valve, the valve is opened to a certain angle to start the booster pump, when the faucet is closed, the water in the water pipe does not flow, the valve will return to the closed state by the thrust of the spring (the attraction of the magnet), so that the pump is closed. The other is controlled by the pressure switch, when the faucet is opened, the pressure in the water pipe is less than a certain pressure, the water pump starts to start, when the faucet is closed, the water pump continues to work, and the water pump will stop working when the pressure reaches the set pressure.

There are three ways to adjust the pressure switch of the automatic hot and cold water self-priming booster pump:

First, the water inlet pipe is not well sealed, resulting in air being sucked into the pump, check the pipe joints, and seal the joints.

Second, the mechanical seal of the automatic self-priming pump for hot and cold water is broken, and air is sucked in from the seal. In this case, a new mechanical seal needs to be replaced.

Third, the water level is too low, which has exceeded the effective water absorption range of the hot and cold water self-priming pump, and the effective water absorption range of the self-priming pump needs to be controlled within 6 meters as much as possible. Note: The flow control switch is composed of a check valve stainless steel spring and a magnetic switch, which is used to detect the size of the inlet and outlet water flow of the pump, so as to achieve the purpose of controlling the start and stop of the pump.

It is forbidden to install the automatic hot and cold tap water self-priming pump in the reverse and vertical installation, the inlet level can not be installed, when the pump inlet and outlet pipes are connected to the power supply for a few seconds, the automatic hot and cold tap water is normal for a few seconds, but the idle time can not be too long, so as not to affect the sealing life of the dry turn.

The cold travel water is all tap water, which itself is the pressure of the atmosphere of Sihe Qingsheng, so there is no need to increase the pressure.

Summary. Before installing the automatic multi-purpose self-priming pump for hot and cold water, it should be checked that there is no slag in the pipeline, if there are impurities and dirt, etc., it will cause damage to the pump, and the installation of the automatic self-priming pump for hot and cold water should be installed in a place that is convenient for future maintenance and replacement.

When installing the automatic hot and cold water self-priming pump, pay attention to the direction of the water flow, with the inlet on the side and the outlet on the top.

The pressure switch of the automatic hot and cold water self-priming pump does not need to be adjusted under normal circumstances due to the special reasons of the installation occasion, if the automatic hot and cold water booster pump cannot be used normally due to special reasons in the installation occasion, the pressure switch must be adjusted, please let the company's after-sales personnel guide the commissioning. Due to the flow control, the automatic multi-purpose self-priming pump for hot and cold water can only adjust the starting pressure of the pump, and cannot control the switching pressure of the pump.

The failure of the self-priming booster pump for hot and cold water indicates the fault overpressure.

Due to the flow control, the pressure adjustment of the automatic hot and cold water sedan car multi-purpose self-training stool suction pump can only adjust the starting pressure of the pump, and cannot control the switching pressure of the pump.

The fault light indicates what is the cause of overpressure.

Overvoltage is overvoltage, and the general voltage regulator is in the range of 160-250.

What does overvoltage mean?

It's just over the voltage range.
