Thick pump common troubleshooting methods

Failure reasons 1. Start difficult 1. Liquid is not filled pump chamber. Frictional resistance larger: 2. Gland packing pressed too tight. Between the shaft and the filler friction torque is too large. 1. Use a pipe clamp to move the spindle pump spindle 3 ~ 6 turn: 2. Adjust the packing gland. 2. No liquid after starting 1. There is a lot of air inhaled: 2. The motor is not steering: 3. Fluid viscosity is too large. 1. Check the suction port liquid level is too low. Whether the suction tube leaks 2. Tune the motor any two-phase into the line: 3 dilute feed solution. 3. The pump has a lot of vibration or noise 1. The motor is not the same as the pump shaft: 2. The pump sucked into the air or liquid mixed with a lot of air - 1. To re-adjust the coaxiality: 2. Check the material level. Remove air from inhalation liquid. 4. During operation, a significant drop in flow 1. Bushing wear. Clearance increases: 2. Speed ​​reduced: 3. Wan shaft section or shaft damage transmission failure: 4. Suction pipe into the liquid depth is not enough. Air into the pump ^ 1. Replace the bushing. If necessary, for the screw: 2. Check the power and motor: 3. Shutdown maintenance. Replace shaft 朕 shaft section or around the axis: 4. Off a small inhalation height. Once immersed into the depth of the inhalation of liquid in the feed fluid to exclude 5. Motor overload 1. Head over the pump stroke too much: 2. Fluid viscosity is too high: 3. Voltage is too low 1. Minimize the pipe head Loss or replacement of high-lift pump. 2. Dilute the feed solution: 3. Check the cause. Increase the voltage to the specified value. 6. A large number of shaft seal packing leakage 1. Gland is too loose: 2. Packing wear: 3. Import and export position in the opposite. 1. Adjust the gland: 2. Replace the packing: 3. Take the middle flange port as suction port.

Our key products are hexabromocyclododecane using as fire retardant. As the pioneer of the fire retardant of hexabromocyclododecane, our technicians not only own independent intellectual property, we also accumulated years of management , manufacturing and market expansion experience. This product is a white crystalline powder, theory of bromine content is 74.71% , the density  of 2.36g / cm3, it has excellent thermal stability, good dispersion. The product is a alicyclic Flame Retardant with high bormine content.The Hexabromocyclododecane(HBCD) is a kind of high bromine content of alicyclic adivitive flame retardant, its characteristics is low dosage, good flame retardant effect, low impact on the physical properties of material and so on. Mainly used for EPS (expandable polystyrene), polypropylene fibers and as flame retardant for styrene resin . It also can be as a flame retardant adivitive of  polyethylene, polycarbonate, unsaturated polyester plastics. Also can be do retardant treatment for knitting material, styrene-butadiene rubber, adhesives and coatings, and unsaturated polyester resin. Packed in net weight 25kg kraft paper bags or 1000kg jumbo bag. You also can contact us for other flame retardant such as Melamine Cyanurate MCA, Ammonium polyphosphate APP, zinc phosphate
melamine polyphosphate, magnesium hydroxide, decabromodiphenyl ethane, decabromodiphenyl oxide, melamine phosphate, Flame Retardant Masterbatch, aluminum hydroxide, Melamine and so on.
