Submersible electric sludge pump, also known as submersible sand pump. The submersible electric sludge pump is a coaxial integration of the motor and the sand pump. There is a stirring impeller at the bottom of the pump body, which can stir the deposited sludge to form a turbulent flow and realize high-concentration transportation. The submersible electric sludge pump submerge directly into the water, eliminating the steps of filling in water, and the operation is relatively simple. TAI’AN OCEAN PUMP brand ZJQ series submersible electric sludge pump is made of high-quality and high-wear-resistant alloy material by precision casting. It is also used in the river sand pumping industry.

Before the customer operate the submersible electric sludge pump, the sales engineer of Taian Ocean Pump will definitely tell the customer to test the motor steering first. It is strictly forbidden to reverse the submersible sand pump. Be sure to turn on the motor to try the steering.After confirming that the steering is consistent with the marked steering, continue to work.

The normal rotation of the submersible electric sludge pump – when the pump is working vertically, looking from top to bottom, the impeller rotates clockwise. When the wiring is wrong, it will cause the submersible electric sludge pump to reverse, and the following hazards will occur when reversed:

  1. The maximum head of the submersibleelectric sludge pump is greatly reduced, and the flow rate will become smaller at the same head;
  1. The efficiency of the submersibleelectric sludge pump will decrease, the maximum power of the pump will increase significantly, and the motor will be burned due to overload in severe cases;
  1. The vibration and noise of the submersibleelectric sludge pump will increase, the oil leakage will increase, and in severe cases, the mechanical seal will fail and be scrapped;
  1. The sediment in the pump casing is difficult to discharge, and it will accumulate more and more, the impeller will be quickly worn out and scrapped, and in severe cases, the submersibleelectric sludge pump will be blocked and the motor will be burned.
  1. When the submersibleelectric sludge pump is reversed, the impeller, the front and rear guard plates are worn out, and the wear starts from the inner concave surface (back surface) of the impeller of the blade, which is faster than normal use.
  1. If the bottom sand suction plate of the submersibleelectric sludge pump (mesh filter plate, used to intercept particles and impurities such as stones) is damaged, large particles of solids will be sucked into the pump casing, and the reverse impeller will be stuck, which will cause damage to the impeller and pump casing.

Therefore, it is strictly forbidden to use the submersible electric sludge pump in reverse. So how to judge whether the submersible electric sludge pump is reversed? The way to judge the inversion is:

  1. Install a gate valve and a pressure gauge on the outlet pipe of the submersibleelectric sludge pump. When the submersibleelectric sludge pump is tested, the gate valve is closed, and forward start and reverse start respectively. The larger value of the pressure gauge is the forward rotation start. and record the pressure value for later judgment of reversal.
  1. If it is not convenient to install the pressure gauge on site, judge whether it is reversed by observing the outlet flow rate and testing the outlet pressure by hand.

Slurry pump is designed and engineered for complex heavy-duty pumping applications to handle high mixture densities such as sand, slurry, sludge, wastewater and gravels, etc. Submersible slurry pump is the kind of widely used slurry pumping equipment that is submerged into the fluid for slurry pumping applications, the submersible slurry pump can be directly powered by either a hydraulic or an electric motor assembled within a protective case which features combat structure, high efficient and flexible operation, etc. TAIAN OCEAN Pump Co., Ltd (OCEAN Pump) is the professional submersible pump manufacturer and supplier who has been dedicated to designing and manufacturing a complete range of heavy duty submersible pumps for over 20 years.
