Why should be equipped with stainless steel submersible electrical control cabinet?

A automatic control needs: General requirements of the pump unattended circumstances, according to user requirements (such as liquid level, pressure level, etc.) automatically run, if there is no control cabinet can not be achieved.

B, the need for safe operation: through the control components, such as with the button to open, close the pump, on the one hand the operator is relatively safe, on the other hand due to the rapid action of contactors, three- Meet the electrical characteristics of the motor requirements.

C, the need for control functions: Some users do not interrupt the water supply needs of production, often with a spare pump, which is a prepared a picture of the control, and some even have to prepare a second, three with a prepared control, Work pump failure standby pump automatically put into operation, and some also need to automatically switch from time to time, if there is no control cabinet, it is difficult to send to do. Another example is the more high-power pumps need to start more than 15kw pressure, which must also have electric control cabinet to achieve.

D, the protection function needs: We already know that the motor can not be overloaded for a long time. Also need to run, which requires overload, short circuit, phase protection, submersible sewage pump but also have water leakage protection, these protection functions are controlled by the electronic control cabinet to achieve.

2. Control the characteristics of the pump number of words

1, single control;

2, one with a prepared;

3, two with a preparation;

4, three with a preparation; before the manual choice of main and standby pump, the main starting method is not marked as a direct start character;

Y: Y-Δ Step-down start:

Z: auto-step-down start;

R: soft start control type characteristic word is not marked as liquid level control;

P: pressure control;

T: temperature control;

S: time control;

K: air-conditioning water pump control;

L: special sewage pump;

X: fire special

3 What pump with electrical control cabinet? The basic requirement is five matches:

A, control the number of pumps in line;

B, match the starting mode;

C, the control type match;

D, the main pump switch match;

E, control power match;

On the number of control pump problems:

There is a single control type (one control one), one with a prepared type (one control two), two with a prepared type (one control three), three with a prepared type (a control four), etc. Manual switching and automatic switching time automatic switching of the points. One with more than one should have the main pump failure, standby pump automatically put into the function. In addition, some users need special use, according to the special needs of the design on the way of starting the problem: General 15KW the following pumps can take a direct start mode, the rest of the pump, generally can be used Y-Δ starting mode. A variety of pumps can be used soft-start mode.

On the type of control issues:

High water tank life and low water tank drainage is usually used liquid control, including submersible sewage pump control cabinet are equipped with leakage protection, if the user has special requirements, but also with leakage protection. Fire pump is generally used pressure control. Air conditioning pumps (refrigeration pumps, cooling pumps, hot water pumps, etc.) General requirements and air conditioning host linkage Press the cooling tower fan, cooling water circulation pump (summer) or hot water circulation pump (winter) transfer unit sequence, Air conditioning pump control cabinet are not a host for air conditioning control interface.

 On the standby switch mode problem:

General use of common type, that is, before the boot manually select the main pump, the main pump failure standby pump automatically put into operation. According to the special requirements of users choose to switch to switch automatically set type.

On the control power problem: usually refers to a single pump power, do not misunderstand the control of the pump power of the sum.

Business staff to accept the user orders, you can press the above points to determine the type of cabinet specifications.

4 CFK pump electrical control cabinet Features:

 (1) widely used, for a variety of occasions, such as the life of water supply, fire, spray, cooling cycle, industrial control pumps, sewage discharge ......, there are corresponding special model specifications, control motor power range 0.18-250kw.

 (2) excellent quality, selection of international and domestic brand-name electrical components and high-quality standard cabinet, well-designed, well-produced.

(3) Various functions, from one control to one control Four, main and standby pump optional combination, a variety of starting methods, various types of control, automatic fault switching, any selection, but also designed for users, or by users For drawing production.

(4) service satisfaction, ready to provide pre-sale technical advice and timely provision of after-sales service, so that users worry-free.

2.1.5

Electrical control cabinet installation and commissioning points:

 A, check the power level, pump, cabinet to match;

B, check whether the components inside the cabinet off, wiring is not strong, bad signs, be excluded;
