How to install small concrete pump pipe

Small concrete pump is a powerful small concrete mixer pump, it subverts the traditional pouring concrete pouring form, combined, greatly facilitate the majority of users. Like a large concrete pump, the mixing pipe is also sealed with a rubber ring and received by the pipe clamp. How to install a small concrete pump pipe mixing trailer pump machine used seamless steel pipe delivery pipe length of 1 m, 2 m, 3 m and other commonly used configuration, the deployment of elbow use, and the elbow and 15 degrees, 30 degrees, 45 Degrees, 90 degrees, etc., and according to elbow length is not the same as divided into large elbow, small elbow, Hui Long Machinery K5 can be satisfied with the delivery of concrete pipe placement request. Stirring the pump pipe device: convergence agitation drag pump pipe machine, usually 2 to 3 people with higher power devices. When installing the pipeline, it should first check if the pipeline is left with the concrete remaining from the previous construction and if it is not cleaned in place, or simply block the concrete during transportation. It is also important to have an accurate reception sequence, or the concrete mixer conveyor is simply pumping to cause the pipe to crack from the joint. Mixing conveyor to receive, must pick up from the pump outlet, that is, from the front to the back, must not be connected to both ends, then the center. After the pipe is connected, the outlet of the pump, the bend pipe and the vacant pipe should be fixed and strong so as to prevent the pipeline from moving and damaging the pipe. When installing the rubber sealing ring, ensure that the sealing ring is embedded in the flange groove of the pipe. When locking the pipe clamp, ensure that the inner wall of the pipe clamp and the sealing ring are well-matched and the seal is tight to ensure that the concrete will not leak when passing through the pipe.

SIC

Emery, also known as Silicon Carbide (SiC), is produced by high-temperature smelting of resistance furnaces using quartz sand, petroleum coke (or coal coke), and sawdust (need to add salt when green silicon carbide is produced). Silicon carbide also has a rare mineral, Moissanite, in nature. Silicon carbide is also called Carbon silica. Among the non-oxide high-tech refractory raw materials such as C, N, B, etc., silicon carbide is the most widely used and the most economical one, and it can be called gold grit or refractory sand. At present, China's industrial production of silicon carbide is divided into two types of Black Silicon Carbide and green silicon carbide, are hexagonal crystals, the specific gravity of 3.20 ~ 3.25, the microhardness of 2840 ~ 3320kg/mm2.

Silicon carbide has two common basic varieties of black silicon carbide and green silicon carbide, both of which are α-SiC. 1 Black silicon carbide contains about 95% of SiC. Its toughness is higher than that of green silicon carbide. It is mostly used for processing low tensile strength materials such as glass, ceramics, stone, refractory materials, cast iron and non-ferrous metals. 2 Green silicon carbide contains more than 97% SiC, self-sharpening, mostly used for processing hard alloys, titanium alloys and optical glass, also used for honing cylinder liners and grinding high-speed steel cutters. In addition, there is cubic silicon carbide, which is a yellow-green crystal made by a special process, used for the production of abrasives for bearing superfinishing, surface roughness can be processed from Ra32 ~ 0.16 microns to Ra0.04 ~ 0.02 micron.
