Trade Assurance HPP-VD3V Series Toyooki Oil Pump HPP-VD3V-L40A5-A HPP-VB2V

The HPP-VD3V-L40A5-A plunger pump uses a makeup pump to supply oil. After 3000 hours of operation, the operator needs to inspect the plunger pump 1-2 times a day to check whether the hydraulic pump operates with a normal sound. If it is found that the speed of the hydraulic cylinder decreases or the vehicle is stuck, the make-up oil pump should be disassembled and inspected to check whether there are scratches on the edge of the impeller and whether the clearance of the internal gear pump is too large. For self priming plunger pumps, the oil in the hydraulic tank should not be lower than the lower limit of the oil gauge, and a sufficient amount of hydraulic oil should be maintained. The higher the cleanliness of the hydraulic oil, the longer the service life of the hydraulic pump.

The components must pass the inspection, the material code meets the drawing requirements, the surface is cleaned, and the mating surface is coated with engine oil. The bearing box should be cleaned and coated with oil resistant enamel, and naturally dried for 24 hours. After passing the inspection, it can be assembled. 2. Assembly of bearing and shaft: The bearing is heated to 90 ℃ - 110 ℃ in a heating furnace and installed on the shaft for cooling. Install the bearing gland on the left side of the bearing box, then install the bearing and shaft components into the bearing box, lean against the left bearing gland, and measure the clearance between the drive end bearing gland and the bearing outer ring. The clearance for the za centrifugal pump is 0-0.42mm. If the bearings of the za centrifugal pump are used in pairs, install and use a locknut to lock the bearings until the outer rings of the two bearings can rotate relatively slightly to obtain an ideal clearance. 3. Assembly of mouth ring and impeller, centrifugal pump body When assembling mouth ring and impeller, centrifugal pump body, it is necessary to ensure that the periphery of mouth ring is evenly installed into the impeller or centrifugal pump body
