Devices of the ASN type are designed for top loading and bottom loading/unloading of oil and oil products, as well as aggressive and non-aggressive liquids into road tanks. The devices are used in the oil, petrochemical and chemical industries.
Devices of the ASN type are easy to operate and are suitable for necks of any diameter, locking systems and lid opening angles. Are made in two design executions - the console and a strut.
The riser version implies a loading device with its own support post and a foundation plate for fixing the proposed loading station to the foundation.
The console version is used in cases of attaching the device to existing metal structures (trestle, mast, column). Based on installation requirements, the product inlet can be either from above or from below.
To balance devices of the ASN type, the following can be used: a system of counterweights (weight) or a spring balancer (shock absorber). The system of counterweights for balancing the ASN allows you to effortlessly control the device. Setting up this system is simple in comparison with similar balancing devices.
The spring balancer for balancing the ASN allows you to reduce the size of the loading device while maintaining reliable and easy control and facilitate the process of bringing the device into working position.
The devices are equipped with a locking mechanism in the working position; when performing operations, they exclude spontaneous movement of mechanisms.
The devices can be equipped with both a solid filling pipe and a telescopic one. The retractable telescopic tip provides the length necessary for safe contact with the bottom of any tanker or the distance from the end of the filling device to the lower generatrix of the tank did not exceed 200 mm. The tip is made of non-sparking material and its design prevents the product jet from falling and splashing at the beginning of the pouring operation.
Also in the set of devices it is possible to use a transitional cone, which takes into account the variety of diameters of the tanker necks. The safety of the product filling process is ensured by the sensor of the limit (emergency) filling level of the truck tank, which ensures that the working medium does not overflow over the edge of the tank neck.
Easy movement of devices without distortions is provided by three-row hinges. Two ball tracks and one roller, providing easy movement of devices without distortions during the entire service life, the roller track perceives significant lateral forces, which can significantly increase the life of the hinge before replacing it.
The design of the filling devices ensures the complete release of the filling pipe from the product and excludes the possibility of its spillage onto the tank at the end of the filling. The collection of drops and possible residues of oil products from the filling device, which is in the garage position, is carried out in a drip collector.
ASN-N type bottom loading/unloading devices are designed for sealed bottom loading/unloading of oil and oil products into road tanks. ASN-N is connected with API 1004, CamLock, KAMVALOK, PVA and other types to the valve of the tank truck, the steam outlet sleeve is connected to the vapor outlet valve. Bottom discharge/filling devices are completely hermetic, which eliminates the loss of product due to volatilization of the vapor-air mixture. They also allow filling simultaneously into several tank compartments, which significantly saves the downtime of the tank truck under loading.
The devices have several levels of automation depending on the requirements put forward to the filling control method:
- Without control - the device does not have any shut-off or control valves.
- Manual termination - the device is completed with a butterfly valve directly on the loading device or shut-off valves installed in front of the device;
- Automatic loading stop - the device is equipped with a shut-off filling valve DKP-80/1, which works without the use of electricity;
- Control system based on a programmable logic controller and electrically controlled shut-off valves;
- Commercial accounting of shipped products by volume and (or) weight.
