1. Sewage pump is a pump and motor Siamese, and at the same time submerged work under the pump products, compared with the general horizontal pump or vertical sewage pump, the sewage pump clearly has the following advantages: 1. Structure Compact, small footprint. The sewage pump can be directly installed in the sewage tank due to its submerged operation. There is no need to build a dedicated pump house to install the pump and machine, which can save a lot of land and infrastructure costs. 2...
Turbine groove butterfly valve is a relatively new valve products. It combines the advantages of ordinary butterfly valve, supplemented by high technology, it has a lot of advantages, suitable for some demanding conditions. 1, easy to operate Turbine butterfly valve butterfly valve clamp connections with light weight, fewer bolts, easy to install the advantages of even the novice can easily use. 2, reliable quality Turbine butterfly valve technology level is very high, with a novel C-type...
Due to the small total amount of media to be controlled, small flow and minute flow rate adjustments have always been a challenge in industrial automation process control. Before we MFR patented small flow control is 100L / h, never done 10 L / h. Small flow control valve is the rated flow in the 10L / h regulation. At that time, an old customer used the fuel control condition, which required a flow of 10 L / h. (That is, we usually mention the home oil 2 mention so much.) 5L). Regulating valve...
Ultrasonic level meter installation precautions: When the probe reaches the liquid level, it will be reflected back to the probe. After receiving the probe, the probe will calculate the time from the wave to the receive wave to obtain the measurement distance. The installation height TH minus the measurement distance L will get the current level. Meter range refers to the instrument can measure the distance, the installation height TH should be less than the range. Instrument blind area refers...
Water treatment, the pipeline as an essential transport liquid, gas, or gas-liquid mixture of the device, the size of its diameter usually determines the delivery capacity, so today Xiaobian and we will understand the pipe diameter DN What is the difference with De? DN DN refers to the nominal diameter of the pipe, Note: This is neither the outer diameter nor the inner diameter; should be associated with the early development of pipeline engineering and English units; commonly used to describe...
Magnetic flap level gauge fault and troubleshooting High temperature magnetic flap level gauge magnetic float in the course of the magnetic float degaussing degaussing, degaussing and thus lead to failure of the magnetic flap level gauge. High temperature magnetic flap level gauge (especially the high temperature and high pressure magnetic flap level gauge) its use temperature is generally more than 180 degrees Celsius, the installation can be demounted with a certain degree of danger. Magnetic...
The effective sealing of high-pressured residue pumps and valves depends on the overall condition of the individual components. Special attention must be paid to the fact that Postel is convinced that the equipment needed to replace the packing has been effectively isolated on site and in the system prior to packing. The following is used to guide the maintenance staff, engineers and assemblers to properly install and adjust the packing. 1, the tools needed in the removal of the old packing...
In the industrial production process, the glass tube level gauge is mainly responsible for the on-site testing of the liquid position in the liquid storage equipment. It is a traditional on-site liquid level measuring tool. To ensure that there is no error in the measured data, you need to understand the precautions for the installation and use of the glass tube level gauge. Changzhou Chang Fa Instrument Co., Ltd. introduced below for reference. Glass tube level gauge installation and use of...
Residual oil pump vibration aging depends on the choice of vibration aging process. Vibration aging process is more complex, must be box-like parts of the pre-vibration process analysis, design and optimization of vibration parameters to improve the effect of vibration aging. According to the workpiece material, structure, the form and process of manufacturing rough, analysis of the distribution of residual stress field box, dimensional accuracy requirements, as well as the working load, the...
Product details First, the structural features Turn the handwheel clockwise to close the manual control valve, then valve stem driven valve flap down until the two conical sealing surface contact is strictly prohibited until the pipeline is closed. The manual valve factory production applies to the sound bar central heating and district heating the best energy-saving products to adjust the flow-based. Second, the use of the manual control valve for nominal pressure ≤1.6MPa and ≤2.5MPa medium...
YHB vertical gear pump seal leakage caused by a run, a sudden leak in normal operation. Sudden leakage in operation a few due to normal wear and tear or have reached the service life, and most are due to larger changes in operating conditions or improper maintenance. Botou City Taibang Valve Manufacturing Co., Ltd. 1, pump down, cavitation or longer pressure, resulting in seal damage; 2, the actual output of the pump is small, a large number of medium pump cycle, heat accumulation, causing the...
General requirements for valve installation: (1) The valve should be located in an accessible, easy to operate, maintain the place. Valves on a row of pipes (such as pipes leading to and from the installation) should be centrally located and considered to be equipped with operating platforms and ladders. Parallel arrangement of valves on the pipeline, the centerline should try to get together. The clearance between the handwheel should not be less than 100mm, in order to reduce the pipe...
The third edition of "Valve Selection Guide" introduces the basic knowledge (such as usage, classification, parameters, model numbering), the basic principles (such as sealing, material, flow, etc.) Valve selection (such as gate valve, butterfly valve, ball valve, globe valve, plug valve, diaphragm valve, nuclear valve), a variety of automatic valve selection (such as safety valves, steam traps, valves, check valves, Hydraulic control valve, oil and gas pipeline key valve), and related...
Pneumatic butterfly valve maintenance methods 1, pneumatic butterfly valve in the use of the process, should always be kept clean, the transmission thread must be regularly lubricated, found that failure, should immediately stop using, identify the cause clear the fault. 2, gland bolts should be evenly tightened, should not be pressed into a crooked state, so as not to hinder the stem stem movement or cause leakage. 3, the installation, the valve can be connected directly by the device...
Spring Festival is coming, air compressor has been used for 1 year. Air compressor in the use of up to one year, the internal formation of a lot of impurities, such as: grease, coke, sediment, rust, and even partially coking lubricant, therefore, the air compressor cleaning , Has become an important part of the air compressor New Year's work. However, the factory has no professional air compressor technicians, how cleaning became a big problem. Therefore, users too lazy to go for cleaning. Long...
1 Overview With the rapid development of the petroleum, chemical and gas industries, and especially the widespread use of liquefied natural gas (LNG) as an emerging energy source, the demand for cryogenic valves for LNG has greatly increased. According to the national energy strategy, China will actively participate in the development of the world oil and gas market. Currently, the NDRC has planned to build 11 natural gas receiving stations in Guangdong, Fujian, Shanghai, Shandong, Zhejiang,...
Effective control of high-speed rotation of the spindle bearing temperature rise is an important indicator of the spindle, the spindle temperature rise and bearing are closely related. Methods to reduce the bearing temperature rise are: (1) to reduce the dynamic friction bearing; (2) to adjust and improve the bearing cooling environment. Commonly used electric spindle lubrication in the following ways: 1. Grease lubrication Under normal circumstances, the bearing unit of time calorific value...
