Centrifugal pump alignment method, pump alignment method The purpose of horizontal centrifugal pump alignment is to make the center line of the water inlet and outlet of the horizontal centrifugal pump and the pump axis line completely consistent with the corresponding center line planned during the concrete foundation pouring of the horizontal centrifugal pump, so as to be consistent with the motor or diesel engine. Take the horizontal double suction centrifugal pump as an example to align the centrifugal pump: take the vertical and horizontal center lines as the standard, draw a mutually vertical intersection center line in the air above the horizontal centrifugal pump equipment, hang two vertical lines on the two lines, and move the horizontal centrifugal pump so that the center line of its inlet and outlet coincides with the vertical line hanging on the axis. See the following diagram for the alignment method of centrifugal pump During the alignment of the horizontal centrifugal pump, if it is found that the position of the anchor bolt hole is incorrect, or the size of the anchor bolt hole of the horizontal centrifugal pump and the drawing in the attached instruction manual are not aligned, the bolt hole is not aligned with the bolt, or there is no room for movement after alignment, then appropriate measures must be taken, such as increasing the anchor bolt hole of the pump, knocking the bolt, etc., to make the alignment deviation of the horizontal centrifugal pump not exceed the specified value. The alignment method of single-stage single suction centrifugal pump is the same as the above method. It is OK to align the axis line. It should be noted that the outlet center of the single-stage centrifugal pump should meet the design outlet pipeline installation position stainless steel electric ball valve is plugged into feed hole when matters needing attention

Ceramic heat exchangers Ceramic heat exchangers have the following characteristics: a. High temperature resistance, corrosion resistance, good heat exchange effect and high energy saving rate. But the part where the metal heat exchanger is placed on the ceramic heat exchanger is quickly burned out.Vacuum heat treatment of aerospace materials b. The use method of the ceramic heat exchanger is direct, simple, fast, less one-time investment, low investment cost, stable heat exchange temperature, high efficiency, long life, no blockage, no air leakage, easy to replace, and there is no gas when switching waste away.Vacuum annealing process of automobile half shaft c. In terms of service life, the ceramic heat exchanger is several times or dozens of times that of the metal heat exchanger under the same conditions.Advantages of vacuum sintering of cemented carbide If the heat exchanger is not used, the temperature of the combustion-supporting air is normal temperature (-10℃-40℃), but the temperature of the combustion-supporting air heated by the ceramic heat exchanger can reach 300℃-800℃, which can not only achieve the purpose of energy saving, but also improve the environmental benefits.Linear Optical Axis Vacuum Quenching The waste heat recovery and utilization of the heating furnace can achieve an energy saving rate of 1% to 2%.

Heating furnaces, various industrial furnaces, and boilers are all high-energy-consuming kilns that consume a lot of resources. When the heating furnace heats the ingot, the temperature is high, and the flue gas takes away a large amount of high-temperature heat, resulting in wasted waste and low heat utilization rate. Measures to save energy and reduce consumption include: 1. Paint RLHY-2 black body radiation energy-saving paint on the inner wall of the heating furnace, increase the radiation rate of the refractory material of the heating furnace wall, and speed up the radiation heat transfer in the furnace. This product can achieve an energy saving rate of 10%~20%.Wave spring vacuum heat treatment 2. The high emissivity barrel-shaped device is installed on the inner wall of the heating furnace, which also plays the role of improving the emissivity of the refractory material of the furnace wall, accelerating the radiation heat transfer in the furnace, and the energy saving rate of the product is 3%~6%. The disadvantage of this method is that The investment is too large and the cost recovery period is relatively long.Vacuum Heat Treatment of Hand Hacksaw Blades
