B side will not build pressure at the pump

1 comments:

Mr. Anderson

The B side may not be building pressure at the pump for the JHPK H30 due to a restriction in the B side hose or issues with the booster pump. A restriction can block material flow, and if the booster pump shaft is not properly lubricated or if crystallization occurs, it can damage seals and affect pressure build-up.

IV. System installation 4.1. The installation of raw material pipe system Lead Isocyanate (black) and polyhydric alcohol (white, POLY) to the pump body inlet of the host from material barrels by the feed pump, and connect the raw materials and air pipes to the polyurethane spray gun as following steps.
Page 8 Figure 2 Step 2 , connect the feed pump conveying hose to the discharge hole filtered by the feed pump and the inlet of pump body of the host respectively. See Figure 3. (2) Installation of the discharging system: Firstly, remove the plastic insulation sleeve that outside of the temperature sensor wholly, feed the temperature sensor (armored extra-long thermocouple) at the exit of the main machine exit slowly into the black material pipe through the black material joint of the heat preservation hose group (the hose end is protruding).

Operation steps: When the equipment is fed with air source, put the Run/Retract switch to operation position, then the booster pump begins to work normally. If short-period stop of booster pump is desirable, put the Run/Retract switch to the reset position. For long-period shut down, first turn the Run/Retract switch to the reset position, then pull the lock bolt to release material (pressure release) while keeping the booster pump working.

Figure(8) Figure(9) Temperature setting for temperature controller: JHPK-H30 version equipment control instrument has three temperature controllers, used to set and control temperature for the black material (component A) heater, the white material (component B) heater, and pipeline heater. The black and the white materials are controlled by C16H controller, the control panel of which is shown in Figure (9).

Note: The electrical cabinet shall be operated by an electrician or a trained person. 4.11 Over-temperature protection: The main machine heater, JHPK-H30 equipment, and the heated pipeline are equipped with over- temperature protection circuit. When the actual temperature exceeds 55℃, the heating power will be switched off automatically.

4.14 About large volume and portability of the equipment heat preservation pipe set Figure (12) shows the winding up of heat preservation hose set by JHPK-H30 main machine. On the left part, the protruding part of the horizontal booster pump and the protruding tube of the main machine stand form a spatial support, on which the heat preservation hose set may be wound.
Page 17 The general layout of the equipment has given due consideration to spatial usage. Even if more sets of heat preservation hose are received, the designed space for movement and maneuverability can be guaranteed and one operator is able to move the equipment alone. The large volume and the portability of the heat preservation hose sets increase the suitability of the equipment, provide great convenience to the operator, and save labor force while improve the efficiency.

V.System operation 5.1. Pre-operational inspection: 5.1.1 If the anti-solidification lubricant reservoir contains DOP (dioctyl o-phthalate) of no less than 4/5 of the reservoir volume. 5.1.2 .Check that all joints are securely tight 5.1.3. Check that power line is connected correctly. And the protective grounding wire is connected safely and reliably.

Note: Due to expansion of the combined polyhydric alcohol when heated, the main air source pressure of the JHPK-H30 spray system can’t be set at working pressure before operating to avoid damage of the pressure gauge even pipe burst caused by the heating of the raw materials in the pipeline.

Shutdown steps: Step1, Push the main temperature controller knob and make it on a high status. Then the heating system will stop heating. Step 2, check the sprinkler gun. Take the next step after be sure that the sprinkler gun is trouble-free and can operate properly next time.

Page 22 Step 4: Shut down the machine as if in a routine shut-down operation. Note: If performed once every 15 days, this procedure is effective in preventing black material (isocyanate) crystallization in the hose. 5.5.2 Method II: This method is for an excessive period of nonuse of the equipment; for example, shut-down for winter or for an indefinite period of time.

VI. Inspections of flow system and equipment problems As a qualified operator you need to know the following: 1. What is the normal material? 2. How to operate the equipment? 3. What is the normal operation situation of the equipment? 4.

(E) Check the filter of the feed pump. (F) It is best to determine the problems of main body of the feed pump after all other parts have been determined don’t have any problem, and pay particular attention to item (B) of subsection (2) to B in step 3. 4.
Page 25 always submerged in the lubricant, completely isolated from the air. This prevents the feed material from crystallizing on the pump shaft and avoids damage or destruction of the sealing parts caused by crystals. The in-series layout of the functional parts of booster pump, the proper structure of shafting couplers, and the utilization of anti-solidification lubricant assembly at the black material end improve effectively the working condition of seal parts, reduce their wearing and replacement frequency, and reduce significantly the feed material pressure fluctuation when the booster pump reverses the direction.
Page 26 6.3.1 Disassembling the black and the white material booster pumps The power between the black and the white booster pumps and the cylinder shaft is transmitted by coupler assembly, which has a construction as shown in Figure (16). Figure (16) Two half-cylinders with internal recess may engage tightly with the shaft end boss.
Page 27 6.3.2 Tightening the seal clamping cap A seal clamping cap is installed on the delivery end block of both the black and the white material booster pumps. It is provided to fix and secure the seal cup (part No. JAPS-305Y) installed on the delivery end block. The clamping cap force is adjustable.
