Buying pumping equipment is based on taking into account the features of all parts of the system, their comparability, compliance with a particular source (well or well), also for choosing a location for the installation. Installation of the pumping station can be made for different steps: during the construction of the house, drilling a well or repair work.
For the installation, a closed flat level platform (1-1,5 m?) Located in the utility room, basement or for the street. If the best place you think is the corner in the house (bathroom, veranda, building), then you'll talk about good noise insulation, even if the environment is provided with the necessary certificates.
Nuance #1 - building equipment Membrane membranes equipped with an elastic hermetic membrane that divides the compartments with water and compressed air;
Membrane-free, in which water and short atmosphere are not broken, are in the same reservoir.
The membrane is a strong rubber pocket that does not contact the walls of the reservoir in which it is located. Hydrophores with a membrane device are small-sized, have the smallest dimensions and do not require a large area for installation - the best option for homes with a lack of free space. The size of the tank - an average of 30-50 liters. However, as necessary, you can find 80 and 100-liter models. The plan of the pump station with a membrane hydrophore, equipped with a self-priming pump and a water pressure sensor, through which the pump case depends.
The self-priming motor is attached from above (in small models, near large ones - installed close) and connects to tank elastic tube. In order to adjust the pressure of compressed air, a nipple is used. Due to its design features, the membrane structure produces less noise. In some models, it is possible to replace the worn out membrane. If you have to buy a spare variation, be sure of its certification, because the matter (usually rubber) is in contact with drinking water. The plan of the pumping station with membrane-free hydrophore, which has the appearance of a huge reservoir for supports: in the lower part of the tank there is water, in the upper part there is a brief atmosphere. The bezembrannny tank is a vertical cylinder of 100 liters. and more. For the supply of water, complete with a membrane-free hydrophore, a self-priming vortex pump must be obtained. The best pump load should not win 0.6 MPa, because this figure is the largest for a greater number of hydrophores.
Normative standards allow the introduction of pumps with a huge pressure, but be provided with a safety valve whose drain leads to the sewer pipe. For the best functioning of the hydrophore and its protection through pipe breakages, a filter of additional water purification is installed in front of the device.
The correct choice of the hydrophore equipment depends on stabilizing the pressure in the device and the entire water supply system, the best foray at each point (in the kitchen faucet, in the shower, for irrigation of the garden), defense through huge loads.
It should be remembered that the hydrophore case is based on two factors:
change in pressure characteristics
volume used th water.
In other words, the number of automatic on-offs due to a single hour can be different. The standard work plan for the hydrophore: water fills the storage tank, until the pressure switch is activated; the pump is cut again after the tank has been emptied and the pressure increases inside the reservoir.
We will see how the burden affects the start-up. Imagine that the house turned on the tap. The amount of water inside the device began to decrease, and the compressed air cushion, against, multiplies, which causes a decrease in pressure. As the burden has reached a small mark, the pump cuts in automatically and pumps the water before the amount of air is reduced, as it should, the burden will not rise. The pressure switch responds for this and disconnects the pump. The highest indicator of pressure inside the tank is determined by the culprit of the equipment, all the work of the relay is allowed to be regulated without the help of others.
Nuance #2 is the size and burden of the unit
The main reason for who should be on the choice of the volume of the accumulator is the average number of water consumed by the family. The productivity is calculated by focusing on the amount of water spent for 1 hour. There are averaged values, but they are usually taken because of a minimum. For example, a family of 4 persons living in a small private home needs a hydrophore with a capacity of 2-3 m³/h. A large family living in a two-story mansion with a garden plot should disassemble for a performance of more than 7-8 m?/H.
Apart from the dry counting of the number of inhabitants, one should take into account their lifestyle: some people wash one day a week, the other daily. The whole structure of household machines and devices also works for water - washing and dishwashing machines, hydromassage and shower systems, automatic watering of the lawn or garden. Tables offered by manufacturers are designed for installation of equipment by specialists. If you are not able to help others navigate in the schemes, consult specialists in the field of water supply systems installation
All should be taken into account and the greatest burden created by the pump. Usually, an unprecedented hydrophore is equipped with an annotation that serves as a clue: in the table the culprit shows a list of principal values for which the equipment should be identified. The working burden must meet all devices included in the water supply system. These include devices installed in most private homes - different future water heaters (cumulative or flowing), single or double boiler boilers, boiler furnishings.
The burden is exerted at the time of connecting the equipment manually, with the help of adjusting bolts, however strictly according to the annotation. For example, the pump's on-off load is 1.7 bar, the pump's shut-off time is 3.0 bar.
Nuance #3 - the key of the water intake
The selection of the hydrophore in almost everything depends also on the source of water intake, which is:
Well;
hole;
Water supply;
pond;
pool.
In order to fly water from a well or well, you need a strong pump. It works in a continuous mode, including during the time of water sampling and turning off, if the house is closed all the time with taps. To adjust it helps the pressure switch - a very suitable adjustable gun, which allows you to control the supply of water due to the growth or decrease in pressure.
It is possible to remove two versions of the pump. One of them, the pump accumulator, makes the burden and because of this sucks in water, it all has limitations. In addition to the depth (before 7-8 meters), horizontal sections should also be taken into account: 10 meters of a horizontally located pipe=one and a half meters of a vertical pipe lowered into the well. A plan for withdrawing water from a well or well with the help of a self-priming pump. This method has limitations - the largest abyss is less than 8 meters. If the water height is extremely low, the hydrophore is installed steadily in the well, equipping the site for the required altitude. Excessive humidity, even to be a good waterproofing is therefore capable of destroying the advance of time, hence the known method is used slightly in a hopeless situation. The best option for installation is a dispassionate, hot, deliberately equipped cellar. The work plan of the pumping station that carries out the city of water with a submersible pump. A large proportion of wells has a depth of 20-40 meters, which says the relative relevance of this method
It's not surprising, in small houses pumps fail more often. This happens for one reason: the number of on-offs is greater, because water is often recruited, however in small quantities. Each pump model should have a control indicator of the greatest inclusion in the course of the first hour, for example, 25-30 inclusions per hour. If tenants of the house use water more often, first the engine will fail - due to overheating. In order to avoid breakage, it should increase the gap between the inclusions - this is one of the important functions of the hydrophore.
Personal houses located within the city or village are usually connected to a centralized water supply system. All because of the small head often water does not come to the 2nd floor, therefore for the forced supply, a pumping station is also needed. The hydrophore complete with the vortex pump should be connected unswervingly to the water supply. In order to keep the burden unchanged, it is better to choose an engine with inverter control. An approximate plan for the location of pumping equipment is to take water from the water pipe. The importance of this method is to stabilize the water supply to be the missing pressure in a centralized system.
So, the hydrophores are optimal for use in private homes and for cottages with such sources of water, such as shallow wells and wells, unstable water pipes or ponds for the sake of watering the garden.
Nuance #4 - conditions and room installations
The small size of modern equipment allows you to place it in virtually any suitable corner - in the bathroom, for the terrace, in the utility room, in the hallway and even near the sink for the kitchen. The height of the noise can exist different, and its huge performance, of course, will need additional sound insulation.
<
When installing a pumping station , one should keep in mind the standards and requirements for installing electrical equipment and water supply systems in private homes. Some of the rules concern the premises for the installation of equipment:
the room's location is more than 2 mx 2.5 m
the height of the room is more than 2.2 m
a small gap through the hydrophore in front of the walls - 60 cm;
a small gap through the pump in front of the walls - 50 cm.
The requirements are not only for pump equipment, but also for all related systems. All electronic cables, occasions, lighting devices, lamps must have a high level of protection through water. The temperature in the room should not exist minus, the balanced version - through +5? C before +25? C. In a large house there are no problems with the placement of hydrophore: it is often installed together with other pumping equipment in a deliberately allocated room, ensuring suitable access for maintenance and repair
Certainly the presence of ventilation, which ensures a constant cooling of the motor. Insurance through emergency accidents - floor roll and sewer holes with a capacity equal to the pump's capacity. Even the door unit is forced to respond to the installed equipment so that it is possible to make or take out a larger element of the pumping station without difficulty if necessary. The only best option for placing pumping equipment is in the basement of the house, which can also be occupied by a building or a basement
If the vibration and height of the hydrophore noise exceed the standards, or, more simply, interfere with living, it is taken out of the boundaries of the structure and placed in a concrete well - a small insulated and sealed pit in the ground. For the protection of walls through shattering use concreting with a reinforced network, reinforced with waterproofing film. For the sake of insulation, sheets of expanded polystyrene are laid, laid in layers not thinner than 5-8 cm. The ceiling is occupied by a reinforced concrete board, and the door is a hatch closed tightly to the palace. Rainwater can be understood in the slot, hence the top cover is covered with sheets of roofing material or plastic waterproof cover. On sale there are design options that mask sewer and technical hatches, they are made in the form of pebbles or thickets of grass. If the hydrophore is installed unswervingly in a well or well, it must provide a very secure environment through the penetration of water, perform open access to the engine and pump, warm the place.
Descent into the well is carried out according to the ladder fixed to the wall. All conditions are similar to the requirements of placing in a utility room - you will need an explanation, ventilation, sewage drainage and insulation (mainly in the northern regions). It should be kept in mind that the engine of the pumping station is not protected through flooding, hence unsafe for the sake of users. All of the above listed aspects should be considered again for the step of purchasing and selecting the equipment.
