Failure reasons: a, the opposite direction of rotation; b, suction or discharge valve is closed; c, no inlet or pressure is too low; d, viscosity is too high, the pump can not bite material
Countermeasures: a, confirm the direction of rotation; b, confirm whether the valve is closed; c, check the valve and pressure gauge; d, check the liquid viscosity to low-speed operation by the speed ratio of the flow rate is there,
(2) Symptom: Insufficient pump flow
Failure reasons: a, suction or discharge valve is closed; b, the inlet pressure is low; c, the outlet pipe plugging; d, packing box leakage; e, low speed
Countermeasures: a, confirm whether the valve is closed; b, check the valve is open; c, confirm the discharge volume is normal; d, tighten; a large number of leaks affect production, should stop running, disassembly inspection; ;
Second, the operation and maintenance (1) Check before starting all the flange pipe, joints tightness.
(2) Disc drive coupling, no friction and collision sound.
(3) The first start should be injected into the pump liquid.
(4) should be fully open before the start of inhalation and discharge of the valve in the pipeline, closed valve is strictly prohibited to start.
(5) After verifying the direction of motor rotation, start the motor.
Polymer leaf disc filter is also called disc filter element, used for high viscosity melt filtration. The disc filter design maximizes the effective filtration area per cubic meter, realizing the efficient utilization of space and miniaturization of filtration devices. The main material is stainless steel sintering felt or multilayer stainless steel sintered wire mesh.
Features: filter element bear the pressure equably, stable filtration performance, can be repeatedly cleaned, long service .
Polymer leaf disc filter is divided into two kinds, according to the material is divided into: stainless steel sintering felt, stainless steel sintered wire mesh; According to the structure: hard and soft. Among the above types, stainless steel sintered mesh filter material has the greatest advantages of high strength and impact resistance, and sintered felt has the advantages of long service cycle and good air permeability.
