Any pumping station is capable of independently pumping water from a source and delivering it to any point of water intake. In addition, the device can become an intermediary that increases pressure in the system. If the power of the main pump (deep or surface) is not enough, then a station can be connected to it through a hose
The article will talk about liquid level indicators that are used in various industries - from automotive to household and industrial. To automate various processes, it is necessary to control the level of the liquid. This can be done using special sensors. They send a signal to the control unit about the level at which the liquid is in the tank. Next, the main types of sensors and the features of their functioning will be described
The article is devoted to centrifugal surface pumps. The characteristics of such models, as well as operational nuances and methods of application are considered
Semi-submersible pumps are widely used not only in everyday life, but also in industrial areas. This is especially true for vertical models. Their main advantage is the vertical arrangement of the shaft, which makes it possible to place such equipment in narrow and small wells
Sewerage is one of the most important engineering communications of a modern country house. But many owners of such housing are sometimes deprived of the opportunity to call professional vacuum cleaners to clean it, so they have to cope with this task on their own. As a rule, a fecal pump is purchased for this. This article is devoted to a brief overview of these devices and an indication of the most optimal type of this equipment
The article is devoted to household pumping stations for water supply. Considered the design of the unit, the principle of operation, types, operation, etc
Quite often, pumps are used to ensure the normal functioning of the heating system. With their help, you can increase the speed of movement of the coolant. On sale you can find various models presented by the best world manufacturers. However, recently in the ranking of the most popular you can find the Grundfos pump
At first glance, it may seem that a hammer is the simplest of all existing types of hand tools. But actually it is not. What types of hammers exist and how to choose a quality tool?
Distribution comb (collector) can be made by you yourself. First you need to plan everything, and first of all, you should decide on the components of the heating network. It is important to know the number of circuits, the number of heating equipment, as well as the number of additional equipment
Foundation beams are used in the construction of frame structures. The main purpose of their installation is the installation of external walls, which are placed on this base. In this case, the beams are laid on the edge of the foundation, on the concrete solution. On the top of the products it is necessary to perform waterproofing. For this, solutions of sand with cement are usually used
Every experienced home master at least once faced with the need to work with a facade mesh. This material can be divided into two subgroups, namely plaster and facade meshes. Each of them performs its functions, and is also made of different materials, which is why it is necessary to consider its characteristics and features before using the material
Fire-fighting foam is sometimes required during construction work. It has a lot of advantages. For some time, the material is able to withstand an open flame, as well as retain its quality characteristics. If you do not protect some objects with such a composition, then their integrity may be violated, which is sometimes completely unacceptable
