EQUIPMENT FOR RAILWAY TRANSPORT

UNZH type devices are designed for top filling of oil and petroleum products, as well as aggressive and non-aggressive iquids into railway tanks. The devices are used in the petroleum, petrochemical and chemical industries. UNZH type device is a pivotally connected pipeline with a filling tip for the release of the pumped product.

UNZH are manufactured in the "console" design. The console is attached to existing metal structures (overpass, pole, tower). Based on the requirements for installation of the UNZH, the supply of petroleum products can be both from above and from below. A counterweight system or a spring balancer can be used to balance the device. The system of counterweights for balancing the UNZH allows effortless control of the device. The setup of this system is simple in comparison with similar balancing devices.

The spring balancer for balancing the UNZH allows you to reduce the size of the filling device, while maintaining reliable and easy operation. The improved hinge system makes it easy to obtain a filling device with a design on the left or right side without any changes. The UNZH can be equipped with a filling tip for open or sealed filling, together with a steam removal hose. The tip for sealed filling can be made in the form of a cone or a lid, depending on the customer's request.

The telescopic filling tube allows you to reduce the size and facilitate the process of bringing the device into working position. For convenience, a one-piece shortened filling tube can be used when filling high-viscosity products. Easy movement of devices without distortion is provided by three-row hinges (two ball tracks and one roller track, which ensure easy movement of devices without distortion during the entire service life, take significant lateral forces, which greatly increases the service life of the hinge before it is replaced).

Design of the filling devices ensures complete getting out of the product from the filling pipe and eliminates the possibility of spilling onto the tank at the end of filling due to the use of an air valve. The devices have several levels of automation, depending on the requirements for the method of filling control:
• without control - the device has no shut-off or control valves;
• manual stop - the device is equipped with a manual disc valve directly on the filling device or a shut-off valve installed before the device;
• automatic stop of filling - the device is equipped with a shut-off filling valve DKP-80/1, which operates without electricity;
• control system based on a programmable logic controller and an electrically controlled shut-off valve. It is possible to implement remote control of the filling/draining process using the software of the workstation;
• system of commercial metering of shipped products by volume and/or weight using volumetric meters or weight flow meters.
