How to properly use a high-temperature fire tube boiler for fabric dyeings, heat one of the special equipment of high pressure. Agencies, utility companies and the use of a wide range of industries, is dangerous and special equipment. Once an accident involving public safety, it will cause huge losses to life and property of the people and the country. For public safety, people's lives and property safety, according to the State Department's "Special Equipment Safety Supervision Regulations", should be used with boiler note the following: 1, should be accompanied by "technical safety specifications of the design documents boiler factory, product quality certification , safety and use and maintenance instructions, supervision and inspection certificate (safety supervision and inspection certificate performance). " 2, boiler installation, maintenance, alteration. Engaged in the installation of the boiler, maintenance, renovation of the unit shall obtain special equipment installation and maintenance certificates issued by the Provincial Quality and Technical Supervision, before engaging in the boiler installation, maintenance, alteration. Construction unit before construction will be prepared for installation, maintenance, alteration in writing inform the special equipment safety supervision and management department of the municipality or district, and will start informing sent to the local county level Quality and Technical Supervision for the record, told immediately after construction. 3, inspection of boiler installation, maintenance, transformation. After construction, the construction unit To State Quality and Technical Supervision of Special Equipment Inspection and hydrostatic testing of the boiler installation supervisory inspection declaration. After passing by the State Quality and Technical Supervision, State Special Equipment Inspection, County of Quality and Technical Supervision involved in overall acceptance. 4, registration boiler. After the boiler inspection, the use of units must be in accordance with the "special equipment registration and use of management rules", fill "boiler (census) Registration Form", the State Quality and Technical Supervision to register and obtain a "registration certificate to use special equipment safety . " 5, operation of the boiler. Boiler operation must be performed by trained and qualified to obtain "special equipment operator certificate" certified personnel to operate, must strictly abide by the rules and eight systems, six record. 6, check the boiler. Periodic inspection of boiler once a year, not be used without safety periodic inspection of boilers. Safety accessories safety valve of the boiler regular inspection once a year, pressure gauge biannually verified, may not be used without the periodic inspection of the safety accessories. 7, non-pressure boilers will be installed for the boiler pressure. Do not use water level gauge, safety valve, pressure gauge three safety accessories insufficiency boiler.

Thrust working pressure and hydraulic cylinder Xiao Bian told you about steam fire tube boiler for fabric dyeing pressure test working pressure and thrust hydraulic cylinder Henan enough fast boiler's steam boiler pressure test is not enough when the steam boiler pressure test time, how does it work pressure of the limited scope of security is how much, how the steam boiler was not out of danger? We know, whether the newly installed steam boiler or steam boiler in service, the purpose of the hydrostatic test, validate one steam boiler with a capacity for elastic deformation of a metal material in the structure, i.e., the maximum extent of recovery after deformation; Second check tightness and structural strength, but in the "steam boiler provisions" article 207 in table 10-1, the calculation of operating pressure hydrostatic test pressure, no clear that P is a rated working pressure steam boiler, steam or finger the actual operating pressure of the boiler, while there is a difference between the two is essential, such as a table rated working pressure of the steam boiler 1.25MPa when: P = P amount (P actual operating pressure) which hydrostatic test pressure is: P sample = 1.25P + 0.4 = 1.65MPa overpressure test to test. When: PP test = P × 1.5 = 0.7 × 1.5 = 1.05MPa not only than the test pressure above (1.65 MPa), but also smaller than the rated working pressure, if done in this pressure hydrostatic test can only check the steam boiler sealing structure, not the whole purpose of the hydrostatic test. I think that this new installation, repair, every six years running steam boiler hydrostatic test should be clearly steam boilers operating pressure is the rated working pressure steam boiler, except in special circumstances, such as: the use of steam boilers Buck , the pressure should be calculated down after test pressure; actual working pressure is much smaller than the rated working pressure steam boiler, can only tightness test, pressure test is not over. Insufficient thrust of the hydraulic cylinder of the hydraulic cylinder may cause abnormal action or not reasons: 1, causing the movement speed of less than a predetermined value can cause a variety of reasons not the thrust: too low a pressure regulating relief valve, relief valve or regulator ineffective, Remedy: increase pressure relief valve: Troubleshooting relief valve 2, the reverse return starts, since the effective working area is too small not move, Remedy: increase the effective working area

3. Reduce furnace loss, reduce exhaust gas temperature, and improve fire tube boiler for fabric dyeing thermal efficiency

Due to the stable combustion in the furnace, the strengthening of the radiant heat exchange can reduce the chemical incomplete combustion loss; on the other hand, the air preheater utilizes the waste heat of the flue gas to further reduce the smoke exhaust loss, thereby improving the boiler thermal efficiency.

Recently, the party's fast Heli De H2800 fire tube boiler for fabric dyeing successful Jingdong headquarters procurement project. He Lide H2800 party fast adoption of new environmental protection industry leading combustion technology - premix combustion, fuel and air through precise regulation and control to achieve precise ratio, can ensure complete mixing of gas and air, burning more fully. The new technique Ultraten heat exchange elements - wings pipe, is a unique fast side. A unique built-tearing groove design, compared with ordinary heat transfer tubes, the heat transfer area can be increased 5-fold, greatly enhance the heat transfer rate, to strengthen the central flue of the disturbance, so that heat transfer efficiency is better, more energy efficiency .
