pc200 hydraulic pump free sample

Hydraulic piston pumps are differently used and, according to their specifications. The piston pump is also called the hydraulic piston pump, but it has different functions compared to the other types of piston pumps. When it comes to the type of piston pump, the piston pump is usually operated by either two or three-stage.

A hydraulic piston pump is another type of hydraulic piston pump, which is a dual-stroke type and can be divided into two types. One of the different types of komatsu hydraulic piston pumps is another type of high-pressure pump. It is a secondary hydraulic piston pump, and it is also called s secondary hydraulic piston pumps, where the suction type isjected into the outlet of the button.

Hydraulic pumps are commonly used on construction sites, such as load-bearing and loading. There are a variety of komatsu hydraulic pumps, which are commonly used in construction plants, construction sites, and energy-saving industries. It is one of the most commonly used hydraulic pumps, such as komatsu PC200, and Komatsu PVC pumps are one of the most commonly used on construction sites.

Komatsu piston pump is a type of high-pressure pump, known as the komatsu piston pump, or a komatsu piston pump, it is a type of high-pressure pump, also known as the komatsu piston pump, a hydraulic piston pump is a type of high-pressure pump. It is a combination of the two types of pistons, one of them is the komatsu piston pump, also known as the komatsu piston pump, is a type of piston pump, it is a type of high-pressure pump, and one of them is the komatsu piston pump. It is a one of the most commonly used piston pumps, in the form of a komatsu piston pump, or a hydraulic piston pump, for example, is a type of high-pressure pump.

3) In addition to those listed in Table 1-5, have components such as an adapter and hose ready, which are required for configuring a test hydraulic circuit. ★ For information on manufacturing of jigs and components, see "Section 4 Names of Sections and Related Dimensions."

1-7) Preparatory Steps for Test Fig. 7-1 Installation Condition of PumpPerform the following steps prior to this test.1) Installing hydraulic test stand (see Fig. 7-1) Install the test stand so that the sample air bleeder (PDa) turns up. • Fig . 7-1 P Da: Air bleeder (used for air bleeding) P D1 : Pump case drain port on the F side

2) Installing universal joint Since the universal joint rotates rapidly, install it in a level position when connecting, and take action not to cause run-out. Protect the coupling from becoming detached from the shaft. Fig. 7-2 Pump Hydraulic Circuit Diagram3) Configuring test hydraulic circuit (see Appen- dix Figure 1) i) Configure as per test hydraulic circuit dia- gram in the Appendix Figure 1. ★ For the main pump hydraulic circuit dia- gram, see Fig. 7-2.ii) Set up circuits for bleeding air and force-feed lubrication on the rear pump. (See Fig. 7-3.) ★ Use drain port (P D2r) for air bleeding of the rear pump. (See Fig. 7-3.) • Set the drain discharge port higher than the pump discharge port (P1r), because the drain port tends to point downward. • Drain pressure: 0.98/MPa{1kg/cm2} or Fig. 7-3 R Pump Drain Hydraulic Circuit Diagram less ★ Use the plug (PT) for forced-feed lubrica- tion of therear pump. (See Fig. 7-4.) • Flow of forced-feed lubrication: 40 (l/ min) or lessiii) Install pressure gauges on hydraulic detec- tion ports. ★ For specifications of the pressure gauge to be installed, see Appendix Figure 1. ★ For details of port and adjustment sec- tions, see Appendix Table 1.

4) Filling the pump case with oil Pour oil into the pump case (PS port), bleed Fig. 7-4 Locations of R pump case drain plugs the air (P Da, P D1f, and P D2r ports), and fill the pump case with oil. ★ Be sure to perform this to prevent the possibility of damage inside the pump. ★ Be sure to release air from the rear pump. ★ Tightening torque for air bleeder: 7.8 – 9.8 Nm {0.8 – 1 kgm} ★ PT port plug tightening torque: 58.8 – 78.4 Nm {6 – 8 kgm}

5) Cleaning pump assembly Fig. 8-1 Maximum Flow Adjustment Section Clean the pump assembly to check for oil leakage and apply penetrant testing agent to each of valve, plug and input shaft oil seal.

1) Running-in Check for abnormality (pressure, vibration, Fig. 8-2 Detail of Maximum Flow Adjustment Section sound, etc) and oil leakage while the pump is running.

2) How to check and adjust maximum and min- imum pump flow (1) Check piston pumps P 1f and P 1r deliv- ery for the maximum and minimum flow under the predetermined conditions. ★ For the measurement of minimum flow, add the amount of drain at LS pressure port (amount of oil flowing when the stop valve S1 is open = Q3). • Q T = Q1 + Q3 (l/min)

(2) How to adjust pump flow ★ Before making adjustments, place alignment mark. i) Adjust the maximum flow using the adjustment screw (Ma). (See Fig. 8-1.) ★ The maximum flow adjustment sec- tion has been mounted to reference dimensions when the pump was assembled (see Fig. 8-2). [Reference] L1 = 19.6 ± 0.1 mm (Common) • 180° tighten of adjusting screw (Ma): -13.8 l/min
