JYWQ automatic mixing sewage pump Note: (1) before the operation of megger to check JYWQ automatic mixing sewage pump motor stator winding insulation resistance to the ground, the minimum shall not be less than 50 megohms. (2) check the cable for damage, broken and so on. If damaged, it must be replaced in time to avoid leakage; cable cross-section should be matched with current. (3) Do not start the pump when the voltage exceeds ± 10% of the rated voltage. (4) In order to ensure the safe use, the ground wire in the four-core cable must be grounded reliably to prevent electric shock accident. (5) Electric pump dive into the water, should be lifted vertically, does not allow horizontal placement, but can not sink into the sludge. Stop using the pump should be lifted clean, placed in a dry place, and pay attention to antifreeze. (6) It is forbidden to use the cable as a lifting rope. (7) Check the direction of rotor operation, from top to bottom should be clockwise rotation. (8) Outdoor switches or terminals should be protected against rain and moisture. Do not touch the switch when wet or barefoot to prevent electric shock. (9) When moving the pump, it is necessary to cut off the power supply. When the pump is in operation, the person shall not touch the water, so as to prevent the personal accident of leakage. (10) It is forbidden to run the motor out of phase. If the fuse is found to be blown, check the cause before using it, and do not arbitrarily bold the fuse. (11) pump operation, there should be someone management, if there is an abnormal phenomenon should be immediately shut down to check and troubleshoot. (Referring to the end with automatic protection cabinet situation). (12) After six months of normal operation of the pump under the conditions of the specified working medium, the condition of the oil chamber should be checked. For example, if the oil in the oil chamber is milky or precipitated, mechanical oil and mechanical seals 10 to 20 should be promptly replaced. For the use of poor working conditions in the pump, it should be more regular maintenance. (13) The user should select the appropriate flow head according to the actual working conditions in order to achieve the best results. The parameters shown on the nameplate or manual of the pump are the best working condition points, and the user can choose between (0.7-1.2) Double the best use within the flow, prohibit the use of ultra-flow, otherwise the flow is too large, easy to overload the motor too low lift.
Custom Stainless Steel Open End Blind Rivets, made of stainless steel and aluminum, also rivets can be manufactured with standard steel, copper and brass. We can also add various surface treatments and customize sizing to suit clients' specific applications. These rivets utilize a built-in plastic cap to provide waterproof fastening. They also help to prevent corrosion during the working.
Open end blind rivets, also known as pop rivets, are a type of fastener used to join two or more materials together. They consist of a rivet body and a mandrel, which is a thin rod that extends through the center of the rivet.
The rivet body has a hollow cylindrical shape with a slightly larger diameter than the mandrel. The mandrel is inserted into the rivet body and protrudes from one end.
To install an open end blind rivet, a rivet gun is used. The rivet is placed through pre-drilled holes in the materials to be joined, and the gun is used to pull the mandrel through the rivet body. As the mandrel is pulled, it deforms the rivet body, creating a bulge on the blind side of the materials. This bulge creates a secure joint between the materials.
Open end blind rivets are commonly used in applications where access to the blind side of the materials is limited or impossible. They are widely used in industries such as automotive, aerospace, construction, and manufacturing. They offer a fast and efficient method of joining materials, and can be easily installed with basic hand tools.
