Dezhou City, Shandong Province, located in northern China, the winter heating livelihood security is the top priority. According to statistics, the main city such as the German city of existing heating boiler 63 units, for the protection of the safe operation of the winter heating boiler, the past few days, the German city Bureau of Quality Supervision special equipment inspectors to carry out a comprehensive examination of special law enforcement actions against these heating boilers.
Check the main content around the registration and inspection of boilers, operator's safety if the holder case posts, etc to focus your heating boiler operating conditions, in particular the various safety accessories and safety devices especially by the attention of inspectors. By the inspection activities, it may be within the control range as much as possible, to ensure the safe use of heating boilers.
The oil and gas boiler produced by ZG boiler are generally composed of two series, wns series oil and gas boiler series, which can be produced from 1 to 20 t/h, and szs series oil and gas boilers, which can be produced from 6 to 35 t/h. Both series can produce energy saving fired steam boiler for sales and hot water boilers in a wide range.
The energy saving fired steam boiler for sale can be divided into three kinds according to the fuel (electricity, oil, gas), such as electric steam boiler, oil steam boiler, gas steam boiler, etc. According to the structure can be divided into vertical steam boilers, horizontal steam boilers, small steam boilers are single, double-return vertical structure, large-scale steam boilers are mostly three-way horizontal structure. If according to the classification criteria above, there are a lot of steam boilers, take an ordinary fast-packed 4-ton steam boiler. Water is heated into steam in the drum and heat is emitted by fire in the furnace, which is the principle of the steam boiler. Steam The combustion part of a steam boiler consists of a chain grate and a drive device, together with a combustion chamber composed of a boiler rack on the grate frame. Surrounded by refractories. Coal from coal hopper, there are coal gate to control the thickness of coal seam while sealing the front of the air. The lower part of the combustion chamber is the place where the blast enters. This steam boiler has great resistance and needs forced blast. The cinder of a steam boiler, discharged from the back of the grate through Eagle's mouth iron and sent out of the furnace by a slag extractor. Steam boiler flue gas from the back of the boiler, by the steam boiler drum one-way smoke pipe forward, from the two-way smoke pipe back to the rear, then into the dust collector to separate ash, and then through the induced fan from the chimney exhaust Out. The above is the working principle of steam boiler, of course, the operation of steam boiler without other equipment, such as the induced fan not only undertake the task of exhaust flue gas, but also the steam boiler negative pressure operation necessary. There are also pressure vessels, thermometers, safety valves, pressure gauges, pumps, steam pumps, etc. All are essential for steam boiler work. Pump leak problem. The actual output flow rate of gear pump is smaller than that of theoretical flow due to the leakage of gear pump in the process of operation. The main leakage channel of gear pump is through the gap between the two sides of gear and the cover plate on both sides of the gear, which is 75% / 85% of the total leakage of the pump. Radial clearance leakage between gear top circle and inner hole of pump; clearance leakage through gear meshing. Because of the leakage of gear pump, the output pressure does not go, which affects the range of use of gear pump. In order to solve the problem of low output pressure of gear pump, the way of adding floating sleeve or elastic baffle on both sides of gear pump is adopted to reduce the leakage of gear pump and improve the output pressure of gear pump. Radial force imbalance problem. In the working process of the gear pump, the pressure on the outer circle of the gear is not equal, which results in the radial unbalance force at the shaft and bearing of the gear. This radial imbalance will accelerate the wear and tear of the bearing, reducing the bearing The service life also may cause the gear shaft to deform, causes the tooth top and the pump body inner hole friction, damages the pump body, causes the pump not to work normally. The common solution is as follows: (4) opening pressure balance slot on pump, leading high pressure oil to low pressure area, but it will increase pump leakage and affect pump volume efficiency; (2) reducing the size of the pressure chamber, reducing the pressure area acting on the gear teeth, and thus reducing the radial unbalanced force.
Vertical projection which features good energy saving fired steam boiler for sale boiler having a vertical steam energy conversion device, the input of thermal energy by chemical, electrical, and high temperature flue gas to the furnace, thereby converted into electrical energy, and to provide the desired life for people heat, on the safety and convenience of all with excellent product qualities, then what good salient features vertical steam boiler has it? 1, reliable safety performance vertical steam boiler in terms of product safety has a lot of protection, by ground fault protection, overvoltage protection and power protection and other measures to make operation of the boiler can always be in a safe state, when the pressure is too low or there is leakage, the boiler will cut off its own power button, so to ensure the life and personal safety of the boiler. 2, the portable vertical steam boiler operation which is preferably used, which have to see ease of operation and convenient operation of the boiler does not require user intervention excessive production process, just to the introduction of the electric power source control box start button to enter the automatic operation state, and when the job if the amount of water in the furnace suddenly reduced, the vertical steam boiler control system is also used to automatically replenish the water in the water tank to fill the pump through the apparatus in order to achieve high efficiency of production operations process. 3, small size and yield stability compared with the conventional boiler products, the type and volume of the vertical steam boilers are an advantage, not only a wide range, and the volume of the boiler is very small, but it has a large steam room to make product productivity and quality are the most significant upgrade in order to obtain a more stable production company that won the biggest profits. The above is a brief introduction which has a prominent characteristic of a good vertical steam boiler, not difficult to find, the boiler reliability in terms of safety and convenience of operation have notable features, but also in the volume and yield stability also has a prominent feature , production efficiency and product quality to make the most significant upgrade, but also to ensure personal safety as well as the effect of the use of the boiler.

2020-5-23 · Heating accounts for about 55 per cent of what you spend in a year on energy bills, so an efficient boiler makes a big difference.
