Fire pumps are special pumps installed on fire engines, fixed fire-fighting systems or other fire-fighting facilities and used to transport liquid fire-fighting agents such as water or foam solutions. Fire pumps are also widely used in environmental protection, water treatment, fire fighting and other departments, is used to pump all kinds of liquids, is the ideal pump to create a leak-free, pollution-free civilized workshop, civilized factory with the fire fighting system. Fire pumps, whether in production or installation or use, maintenance, have a strong professionalism, zjbetter share with you the steps of fire pump installation for your reference.

1、First hang the foundation bolt assembly on the foundation plate, then put the foundation plate on the foundation, the foundation plate and the foundation between the addition of pairs of wedge pad, the foundation plate plane installed at the correct elevation, the level on the foundation plate, by adjusting the wedge pad, correct the level (≤ 0.075mm / m).
2、Fill the foundation slab and the foundation bolts with concrete.
3、After the concrete is dry and solid, check the level of the foundation plate and the ground bolts for looseness.
4. Lift the pump onto the foundation plate and connect it as a whole, and configure the cooling water pipe.
5, by adjusting the thrust bearing upper cargo pump coupling in the adjusting nut to lift the rotor, the rotor lifting amount for the total rotor tampering power 1/2.
6, adjust the motor coupling centre by adjusting the top wire on the electric motor seat.
7, check the coupling runout, for rigid couplings, pump coupling radial runout and end runout ≤ 0.1mm, for flexible couplings, water pump and motor coupling diameter, directional deviation is less than 0.1mm, end gap load table requirements, unevenness along the circumference is less than 0.1mm.
8, Between the pump and the discharge pipe, generally need to install the gate valve and check valve, the gate valve is installed between the pump and check valve.
Zjbetter was established in 2004, specialising in the production of fire fighting pump sets for 16 years. The company has a 20,000 square foot R&D and production base, which is a high-tech enterprise integrating design and development, production and sales. The company takes strict testing standards as a prerequisite to ensure that the products that leave the factory are perfect and that the service is constantly upgraded. With excellent technology and good service, the company operates with integrity and continues to break through and develop. Welcome your inquiry!
