Servo valve components are: valve body, valve cover, the main valve and vice valve spool, feedback lever, feedback spring and fork, the median adjustment lever, lock nut and so on. Servo valve on the common fault, Tianjin, heat-conducting oil pump manufacturers as follows: A: The main cylinder offset cylinder. Symptom: Two cylinders are synchronized one after the other until the hold-up cylinder processing methods: Loosen the lock nut adjust the rod to observe the movement of the piston rod in the tank slows down, slow down, continue to screw clockwise until the piston Rod stopped. If it becomes faster, tighten the bolt counterclockwise until the piston rod stops. Two: spring break. Symptoms: pumping speed can not be adjusted to the fastest speed of pumping. When the pumping pressure is high, the engine may be decelerated. Approach: replace the spring. Three: spool stuck. Symptoms: There is no pumping or both sides of the cylinder speed is different, may also hold the cylinder. Treatment: cleaning spool or grinding. Four: the lever broken or bent Fault phenomenon: the pumping speed can not be adjusted to the fastest speed of pumping. Pumping pressure is high, the engine may be out of speed, or on both sides of the cylinder speed is different. Remedy: Replace the feedback lever. An oil pump is a lightweight and compact pump, and proposes an oil pump having a housing made of an aluminum-containing material and a movable mold member provided in the housing, wherein the movable mold member Made at least partially of a sinterable iron-based alloy comprising at least one austenite, and wherein the molded article made of a sinterable material has a coefficient of thermal expansion 60% of the thermal expansion coefficient.
Different with Stainless Steel Shot or Steel Shot, Magnetic Polishing Needles is not used for shot blasting and it is used for grind which could help parts have a mirror surface. For some irregular shape parts, it also have a great effects. It is widely used for precision die casting parts for deburring, removing oxide film, rust removal treatment.
Longlived Magnetic Polishing Needles is made from high quality Stainless Steel.
