XBD vertical single-stage fire pump set is based on our IS type pump, combined with the characteristics of foreign pipeline pump, optimization design and manufacture of a new generation of products by itself. Use of fire hydrants in the water, feeding sprinkler system water supply in other occasions cleaning liquid.
Conditions of use:
1. XBD vertical single-stage fire pump set is used for transporting ambient water.
2. The water does not contain corrosive substances and solid particles.
3 Minimum working pressure 0.3Mpa, the maximum working pressure of 1.6 Mpa.
Characteristics of XBD vertical single-stage fire pump products
4, the pump is a vertical structure, import and export of the same caliber, and are in the same center line, as the valve can be installed in the pipeline, compact appearance, small occupation area, low construction inputs, such as protective cover can be placed outdoors
5, the impeller mounted directly on the motor lengthened shaft, short axial dimensions, compact structure, pump and motor bearings reasonable configuration, can effectively balance the pump running the radial and axial load, so as to ensure the operating balance vibration noise of the pump is very low.
6, seal mechanical seal mechanical seal or a combination, the use of imported titanium alloy seal ring, medium and high temperature mechanical seal with cemented carbide materials, wear-resistant, can effectively increase the service life of mechanical seal.
Performance requirements of fire pump is:
1. Maximum flow fire pump shall be 150% of the value of the design, the head is not less than the selected operating point of 65% lift, lift off the pump when not greater than the selected operating point of 140% lift, pump flow 1 2LS, head 1.1 - 1.2 times the fire pump lift.
2. At the same time in the fire pump outlet pipe should be located on measurement flowmeter, flow meter should be able to test 175% of the pump flow rate selected, fire pump pressure gauge set should be greater than 89mm in diameter at the outlet pipe.
