Regular inspection of loos international boiler companys 1, external inspection, usually once a year, this test is in the operating state of the boiler, check the safety accessories, automatic control instruments, protection devices are sensitive, reliable; joints with or without compression component leakage phenomenon; also check the relevant rules and regulations in particular the management of water quality and the implementation of the rules and regulations established. Check the contents of the existing concrete visible external inspection requirements. External inspection has a direct role in preventing accidents. 2, the internal check: every two years a transfer. This test is to conduct a comprehensive internal and external boiler inspections to stop running in the boiler state. The main defect inspecting various boiler heating surface forming operation, such as wear, corrosion, fatigue, deformation or the like, but also to check the security status of the attachment. Specific requirements visible check the current national regulations. 3, hydrostatic test: general once every six years. That can not carry out internal inspection of boilers, pressure test every three years. 1) hydrostatic test pressure should meet the following: the name of the boiler working pressure P test pressure boiler 0.8MPa1.5P, but not less than 0.2MPa boiler 0.8-1.6MPaP + 0.4MPa boiler> 1.6MPa1.25P any pressure superheater the same test pressure boiler body and separable any working pressure economizer 1.25P + 0.5MPa2) and the hydrostatic test requirements of the basic steps: the boiler pressure test, pressure should slow down. First, the cabinet lead off the burner, it can not work. When the pressure rises to the pressure of work, should be suspended boost, check for leaks and other anomalies, and then boosted to the test pressure. Boiler should be maintained for 20 minutes at the test pressure, and then down to the working pressure checked. During the inspection the pressure should remain unchanged. Hydrostatic test shall be carried out when the ambient temperature is higher than 5 ℃, antifreeze measures must be less than 5 ℃. Water pressure test should be maintained above the dew point temperature of the surrounding surfaces to prevent condensation boiler, but it should not cause the high temperature vaporization and to prevent excessive temperature stress, is generally 20 ~ 70 ℃. 3) passing the test pressure condition: 1, there is no pressure on the walls and the weld metal element and the mist droplets; 2, when the working pressure drops mouth inflation does not drip; 3, hydrostatic testing, no residual deformation was found.
The partnership, fast loos international boiler company for the user responsible attitude to have left a deep impression on our fireman boiler operation is not very skilled, fast deliberately sent a party of professional and technical personnel for our on-site supervision of installation, commissioning and training to ensure that the latter can operate our good boiler fireman. --customer feedback
Boiler is a specific type of loos international boiler company, but also a website product and key words, therefore, it is necessary to carry out a comprehensive understanding and understanding, because only in this way, can the proper operation of the boiler and obtain a good use effect, and then, It has good economic benefits in its economic performance. 1. How to ensure the safety of boiler use? To ensure the safety of boiler use, we can proceed from the following aspects: (1) strictly control the operating pressure of the boiler, do not allow it to exceed the prescribed range, once there is a tendency to exceed the prescribed upper limit value, Immediate measures should be taken to address and eliminate. (2) strict control Good boiler temperature, because if the boiler temperature is too high, it will lead to the failure of the furnace tube, resulting in various problems, and affect the normal operation of the boiler. (3) regular boiler maintenance should be carried out. In order to ensure its service performance and service life, (4) in the boiler self-designed design and structure, we should also avoid problems, can not have design defects. Is the boiler oven simple? Boiler oven, from a professional point of view, the operation is not difficult and complex. The temperature of furnace water should be kept in the range of 70 ℃-80 ℃, and the furnace temperature should be raised. It should be carried out slowly to ensure the uniform expansion of all parts of the boiler. 3. Is there a requirement for the upper limit of the boiler's temperature? In boilers, at present, there is no mandatory requirement for the upper limit of temperature, but according to practical operating experience, do not exceed 300 degrees, because if the temperature exceeds 300 degrees, The boiler combustion will be unstable and prone to carbon deposition. In the temperature difference, it is about 10 degrees is better. 4. What is the pressure in the boiler? In this kind of boiler, there are two kinds of pressure, operation pressure and saturated steam pressure, but this is under the condition that the medium of boiler is liquid phase circulation. And, when When the operating pressure of the boiler is low and the temperature is 350 ℃, the operating pressure of the boiler is 0.0588 MPA and the saturated steam pressure of water is 16.43 MPA.
