WTYZ series deep water hydraulic pump

1. Product Introduction

​

​WTYZ Series Deepwater Hydraulic Power Station​
Designed specifically for water conservancy and hydropower projects150-meter-class underwater hydraulic power sourceIt is compatible with hydraulic automatic grab beams, cleaning machines and grabs. The oil tank, oil pump and valve group are integrated into the pressure-resistant tank body. The 7MPa water pressure protection is achieved through a 27SiMn alloy steel /A304 stainless steel (wall thickness 8-10mm) structure, providing stable power for 5t-600t lifting point equipment.

​2. Main functions​

​Precise power control in deep water environments

​

• ​Dual-mode hydraulic output​
  → ​Beam grab controlUnidirectional/bidirectional hydraulic pump output (flow rate ≤14L/min, pressure ≤2.5MPa)
  → ​Decontamination operationHigh-flow hydraulic drive (16L min, pressure adjustable to 12MPa)
• ​Dynamic sealing management​
  → Oil pipe joint +Aviation plugDouble-seal scheme
• ​Wide-area environment adaptation​
  Low-temperature hydraulic oil ranging from -30℃ to 60℃ ensures extremely cold start-up

3. Scope of application​

​Comprehensive coverage of harsh working conditions​

4. Core advantages​

​The four irreplaceable barriers of deepwater engineering​

​✅ high-pressure-resistant structure​

• 8-10mm thick alloy steel/stainless steel cabin (7MPa designed water pressure)
• The inner and outer anti-corrosion coating is stable and reliable

​✅ Component configuration​

• Rexroth/Parker solenoid valves and joint venture brand gear pumps (1.5-2.2KW motors)

​✅ intelligent seal verification​

• The first 30-minute deep dive insulation test

​✅ reliable operation throughout the full temperature range​

• 32 # low-temperature hydraulic oil is supportedIce-breaking start at 30℃​

​6. Option Guidance​

​
​Step 1: Confirm the type of equipment​

▶ ​Hydraulic grab beamSelection path:

• Pin shaft diameter < 200mm →Flow rate: 10L/min​
• Structural forms: can-shaped/circular/square/split type
• ​Type of hydraulic pumpA One-way (standard configuration) B Two-way (customization required)

▶ ​Hydraulic cleaning machine/grab bucketSelection path:

• Mandatory choiceFlow rate > 16L/minPressure: 3.5-12MPa
• Structural form: Circular/split type
• Control cableIt is mandatory to use waterproof socket type​

​Step 2: Selection of the sealing solution​

• ​Tubing pair jointEconomical solution
• ​Aviation plugPlease indicate the model of the aviation plug

​Step 3: Extreme environmental requirements​

• Areas with temperatures below -10℃ →Mandatory use of aviation hydraulic oil​
• Seawater conditionsSpecify A304 stainless steel material​

​Customized promptEquipment drawings, working water depth and pressure curve graphs need to be provided

​Appendix: Iron Rules for Safe Operation​

1. ​Sealing bolts must not be tightened a second timeThe failure risk increases by 300%
2. It must be executed before the first useA 30-minute pressure-holding test in 150-meter deep water​
3. Oil replacement cycleOr 2,000 hours per year(First come, first served)
