seven 、 Configurable man-machine interface products --- Touch programmable terminal;
eight 、 High power water pump can adopt frequency converter or soft starter to realize smooth soft start;
nine 、 Multiple circulating operation modes of multiple pumps to balance the operation time of each pump and avoid corrosion of one pump due to idle;
ten The water supply pressure of the equipment can be adjusted as required to meet the water pressure requirements of the top floor of the building during peak water consumption.
Layout and installation of control cabinet:
one The external dimensions of the control cabinet can be customized according to the user's requirements. Generally, it is delivered with the fixed dimensions of our company.
two If the control cabinet is installed in the water pump room, it should be as far away from the pump body as possible, and installed in a place with less dust and convenient for commissioning and maintenance.
three The control cabinet shall be arranged on the reliable wall, but the concrete abutment (or steel structure support) shall be built below the cabinet, and the abutment height is generally 20-50CM ； The pier area is slightly larger than the chassis size of the control cabinet.
four In order to facilitate the laying of control cables and main cables of the control cabinet, a cable trench can be built, and the control cabinet can be placed on the cable trench. The height of the cable trench and the laying direction of the wire embedded pipes depend on the site conditions of the pump room.
After the product is installed and before it is put into operation, the following inspections and tests shall be carried out ：
one Check whether the paint on the surface falls off and whether the cabinet is dry and clean.
two Check whether the fixing screws and wire connectors of electrical components are loose, and whether the operating mechanism is flexible, without clamping stagnation or excessive operation force.
three . Whether the main electrical appliances are reliable and accurate, and whether the auxiliary contacts are reliable and accurate.
four Whether the connection between the cabinet body and the external wires meets the requirements of the electrical schematic diagram.
five The grounding wire and electrical control cabinet shall be well and safely grounded, and the grounding resistance shall not be greater than ten Ohms.
