1, Vertical fire pump, multi-stage sectional structure. The pump inlet and outlet flanges are in the same straight line, the impeller is hydrodynamically balanced, axial force, a guide bearing at the lower end of the pump. The shaft is fixed to the motor shaft by means of a clamping coupling. The outer cylinder is a stainless steel cylinder.
2, The shaft seal is mechanically sealed.
3, The pump is driven by the motor and rotates in a clockwise direction when viewed from the motor end.
4, The pump outlet is equipped with an exhaust valve (air nozzle), which can ensure that the gas in the pump can be completely exhausted.
5, The impeller can be made of bronze. Avoid rusting between the impeller and the guide vane after long-term shutdown.
I. Installation instructions
1. The weight of the pipeline should not be borne on the pump, otherwise the pump will be easily damaged.
2. The pump and motor are of integral structure. The pump and the motor are an integral structure. It is calibrated by the manufacturer at the time of shipment, so there is no need to adjust the contract when installing it. This makes installation very easy.
3. The foot bolt must be tightened during installation. The pump should be inspected at regular intervals to prevent it from loosening. To prevent the pump from vibrating violently when starting up and affecting the performance of the pump.
4. Before installing the pump, check carefully whether there are any hard objects (such as stones, iron sand, etc.) in the flow channel of the pump that may affect the operation of the pump, so as to avoid damaging the overflow parts when the pump is in operation.
5. For easy maintenance and safety in use. Install a regulating valve on the pump's throttle and a pressure gauge near the pump's throttle, and for high head pumps. To prevent water hammer. A check valve should also be installed in front of the outlet gate valve to cope with sudden power failure and other loss of power accidents, thus ensuring that the pump operates under suitable working conditions and increasing the service life of the pump.
6. The pump is used in suction range situations. It should be equipped with a bottom valve, and the pipeline should not have too many bends in the mouth of the flume, and there should be no water leakage or air leakage in the same inch. To avoid affecting the suction performance of the pump.
7, in order not to make impurities burst into the pump and block the flow channel to affect the performance. A filter should be installed in front of the pump's flume.
8, the installation of pipeline bary for the rotation of the pump rotor parts, should be no grinding sound or jamming phenomenon, otherwise the pump should be disassembled to check the reasons.
