Trochoid pumps have the functions of sucking in and discharging oil. There is a certain discharge volume. In fact, the discharge volume and pressure change linearly under a certain number of revolutions, and the discharge volume is the largest when there is no pressure. The driving force is proportional to the pressure, and the driving force is the largest when the pressure is the largest. Due to the simple structure and high durability of trochoid pumps, they are widely used in industrial equipment.

1. Reasons for trochoid pumps not to suck oil

1. The viscosity of the oil is too high: the viscosity of the oil is too high, the resistance increases, and the pump cannot suck the oil.

2. Improper installation: The installation position of the cycloidal gear pump is improper, or the inlet and outlet pipes are not connected correctly, resulting in difficulty in sucking the oil.

3. Gear wear: The internal gears of the cycloidal gear pump are worn or the bearings fail, making the pump unable to operate normally, resulting in the effect of sucking oil.

2. Solutions to solve the problem that the trochoid pump cannot suck oil

1. Replace the oil with suitable viscosity: According to the specifications of the pump and the use environment, select the oil with suitable viscosity to ensure the normal operation of the pump.

2. Check the installation position and connecting pipes: Check whether the inlet and outlet pipes of the trochoid pump are connected correctly, and ensure that the pump is installed in the correct position to avoid the inability to absorb oil due to inconsistent working surface height.

3. Maintain the internal structure of the pump: Replace gears and bearings in time to ensure that the gears inside the pump rotate flexibly and avoid the occurrence of oil absorption difficulties caused by wear.

3. How to prevent the trochoid pump from failing to absorb oil

1. Keep the pump clean: Clean the cycloid gear pump regularly to avoid oil accumulation inside the pump and affect the normal operation of the pump.

2. Check the internal structure of the pump regularly: Check and maintain the inside of the pump regularly, replace worn gears and bearings, and ensure the normal use of the pump.

3. Keep the working environment stable: During the use of the trochoid pump, try to keep the working environment as stable as possible to avoid the problem of the pump failing to absorb oil due to environmental variables.

In short, the problem of the trochoid pump failing to suck oil is very common; if you cannot solve these problems, or you want to change to a new pump. RicoCNC can bring a series of trochoid pumps, like ANSON PVF-30-35-11 Hydraulic Vane Pump, AMTP-216HAVD A-Ryung T-rotor pumps, AMTP-216HAVB A-Ryung Motor T-ROTOR Pump, and other trochoid pumps.
