In the maintenance of the following three points to find the cause of the malfunction, and the system to improve: (1) check the boom cylinder leakage situation. The easiest way is to raise the boom to see if there is a clear free fall. If the whereabouts of obvious removal of fuel tank inspection, seals have been worn should be replaced. (2) check the control valve. First clean the safety valve, check whether the spool wear, such as wear and tear should be replaced. If there is still no change...
Due to the structure of the displacement limit, it is generally considered gear pump can only be used as a constant flow hydraulic source. However, the attachment and threaded coupling valve scheme is effective in increasing its functionality, reducing system costs and increasing system reliability, and as a result, gear pump performance can approach that of costly, complex piston pumps. For example, installing a control valve directly on the pump controls the cost by eliminating piping between...

The pump does not drain or drain. Caused most of this failure is due to the end of the valve stuck, part of the blockage of water filtration, suction height is too high or suction pipe leakage and so on. Should be checked one by one, respectively, to repair the end of the valve, remove the blockage, to correct the steering and other processing. 2, pipeline leakage or leakage. Mostly because the nut did not tighten. If the leak is not serious, you can smear grout, wet mud or soft soap at the...
Oil production plant three grams grams 00 wells after the hydraulic jet pump drainage measures, the outer exhaust gas flame 4 - 5 meters, Nissan 20,000 cubic meters of natural gas, which marks the first oil company in the third oil production plant hydraulic jet pump liquid production process Success. Well K 006 is located in Upper Wuerhe Formation of the South Permian in the five districts of Karamay Oilfield. After fracturing in September 2005, the well was shut down due to the failure of the...
Inlet pipe and pump body air (1) The pump is not filled with enough water before it starts, sometimes it appears that the water has been poured from the bleed hole, but the air is not completely discharged by rotating the pump shaft, causing a little air to remain in the intake pipe or Pump body. (2) The horizontal section of the inlet pipe in contact with the pump applies a descending gradient of 0.5% or more to the direction of the flow of water, and the one end connected to the inlet of the...

1 Hydraulic pump is a kind of hydraulic pump 2 hydraulic pump has a single circuit and double circuit. 3 The principle of hydraulic pump Its function is to convert the mechanical energy of the power machine (such as motor and internal combustion engine, etc.) into liquid pressure energy. Working principle: Cam driven by the motor rotation. As the cam pushes the plunger up, the seal formed by the plunger and the cylinder decreases in volume, the oil is squeezed out of the sealed volume and...

High Viscosity Pumps In fluid delivery systems, rapid changes in liquid flow rate, flow and pressure, rupture of bubbles, and alternating loads are common causes of noise. Gear pumps that deliver high viscosity liquids are the main source of system noise. High-viscosity pump delivery media is not only an energy transfer intermediary, but also lubrication, sealing and heat transfer medium. The transmission of high-viscosity liquid gear pump should be done at lower power consumption, less...
