Vacuum pump for everyone is not unfamiliar, we can say that we are inseparable from all the shackles of the day. Through the survey found that the rotary vane vacuum pump in the event of problems, many customers will self-repair, can not solve the find professionals, the customer self-repair process many people have misconduct, the following Asian Fluid Network Xiaobian for our specific rotation Vacuum pump repair defects key introduction. 1, first of all to understand the type of pump, characteristics, the current situation. Understand the use requirements, determine the repair guidelines. Before you fix it, be prepared to check it. 2, identify problems, diagnose problems. Discrepancies can save energy. Confirmed to verify. 3, eliminate problems, first simple and complex, easy after the first hard. Do not dismantle without demolition. In order to reduce the lack of special tools and improper operation lead to new damage, changes in orientation and running out of running time. Generally speaking, the splicing rotor is not open apart, otherwise the shape of the public service will not be guaranteed, the rotor will be scrapped. 4, toxic, harmful, corrosive rotary vane vacuum pump, users should be invited to clean, customs and the necessary protective measures to ensure the health of personnel.
Train Parts Casting is one branch of carbon steel precision casting, which is widely used in train markets. Precision Casting Of Train Parts adopts lost wax casting, also called investment casting. In wax pattern process,we mix stearic acid and paraffin wax.
In wax pattern making, as you know, it is better than polyethylene, and the wax deformation is small. In dipping slurry process,most of the suppliers adopt water glass technics in domestic area,but we adopt compound technics or silica sol technics. As you know, carbon steel castings will be much smoother with compound technics (compound of water glass and silica sol technics),this method is so popular with our customers, and the quality is higher than water glass technics, the cost is lower than silica sol technics.
In shell making,we adopt automatic sand-covering production line, which was invented under the guidance of our general manager.The indoor temperature was controlled by air-conditions,keeping the temperature at 24℃±1℃, which can make the castings much more stable,the internal tissues much more well-proportioned.
Our train parts as precision casting products have quality assurance in accordance with ISO9001: 2008, strict material inspection and exact dimension control, with 100% quality control. OEM order is welcome. The parts can be made completely based on your specifications such as drawing, design, sample etc.
